3.1 The Sun

The Sun is a star. It is a huge, spinning, glowing sphere of hot gas. It appears so much larger and brighter than the other stars because we are so close to it. The Sun is the center of our Solar System and contains most of the mass in the Solar System. All of the planets in our Solar System, including Earth, orbit around the Sun. In sun the energy generation is a multi-step process of thermo-nuclear fusion reactions. In the thermo nuclear fusion hydrogen (four protons) combines to form helium (one helium nucleus). The mass of the helium nucleus is less than that of four hydrogen protons and mass having been lost in the reaction is converted to energy. The reaction is represented as

2.1 Introduction

The name thermodynamics stems from the Greek words therme (heat) and dynamis (power), which is most descriptive of the early efforts to convert heat into power. It may be defined as the science that deals with the relations among heat, work and properties of a system. Today, thermodynamics is broadly interpreted to include all aspects of energy and energy transformations, including power generation, refrigeration, and relationships among the properties of matter. It is viewed as the science of energy, and thermal engineering is concerned with making the best use of available energy resources.

Thermodynamics basically entails four laws or axioms known as Zeroth, First, Second and Third law of thermodynamics.

The zeroth law deals with thermal equilibrium and establishes a concept of temperature.

The first law pertains to the conservation of energy and introduces the concept of internal energy.

The second law indicates the limit of converting heat into work and introduces the concept of entropy.

The third law defines the absolute zero of entropy.

The concept of energy was introduced by Newton in the field of mechanics during generalizing the hypothesis of kinetic and potential energies. Energy may be defined as the capacity to do work and it is a scalar quantity. It cannot be seen or observed. Its presence can, however, be felt by the properties of the system. There occurs a change in one or more properties of the system in case of energy transfer. The absolute value of energy of a system is difficult to measure, whereas the energy change is rather easy to calculate. Energy follows the conservation law, one of the most fundamental laws of nature, which simply states that during an interaction, energy can change its form from one form to another but the total amount of energy remains constant, that is, energy cannot be created or destroyed only form can be changed.

1.1 General

Renewable technologies are considered to be clean sources of energy. The optimal use of these resources minimize environmental impacts, produce minimum secondary wastes, and are sustainable based on current and future economic and social needs. Sustainable development requires methods and tools to measure and compare human activities’ and its environmental impacts for various products. Renewable energy sources (RES), which include biomass, hydropower, geothermal, solar, wind, and marine energies, supply 14% of the world’s total energy demand. Renewable resources refer to primary, domestic, and clean or inexhaustible energy resources. Large-scale hydropower energy supplies 20 % of the global electricity need. Wind power in coastal and other windy regions is a promising source of energy.

Renewable energy resources can make a decisive contribution to the economic, social and sustainable development of rural regions in developing countries, yet the consumption of fossil fuels is dramatically increasing along with improvements in the quality of life, the industrialization of developing nations, and the increase of the world’s population. It has long been recognized that excessive consumption of fossil fuel leads not only to a diminishing fossil fuel reserves more quickly, but also has a significant adverse impact on the environment. Such impacts result in increased health risks and the threat of global climate change. Changes to improve environmental conditions are becoming more politically acceptable globally, especially in developed countries. Society is slowly moving towards seeking more sustainable production methods, minimizing waste, reducing air pollution from vehicles, generating distributed energy, conserving of native forests, and reducing greenhouse gas emissions. Increasing consumption of fossil fuel to meet out current energy demands, however, has sounded alarms over regarding potential energy crisis. This has generated a resurgence of interest in promoting renewable alternatives to meet the developing world’s growing energy needs. Excessive use of fossil fuels has caused global warming from carbon dioxide emissions, therefore, promoting renewable forms of clean energy is eagerly required. To monitor the level of these greenhouse gas emissions, an agreement that has fulfills the objectives of the Kyoto Protocol was create with overall pollution prevention targets.

8.1. Vegetables

8.1.1. Tomato (Lycopsarsicon Esculentum)

Temperature: A warm climate crop can tolerate high temperature but cannot withstand frost. Minimum temperature for germination of seed is 8 to 10°C. Night temperature for fruit setting is 12 to 22°C. Critical night temperature for fruit setting is below 12°C. Critical day temperature for fruit setting is above 32°C. If the greenhouse can maintain the temperature as mentioned above then the non-terminal or indeterminate tomato crop can be grown for 10 to 12 month duration.

Variety: Indeterminate (producing flowers and fruits continuously along the stem as it grows) hybrid varieties resistant to nematodes or fusarium or verticilium wilt disease may be selected.

7.1. Introduction

Cultivation of crop is one of the most important aspects on which the success of a greenhouse depends. Principally it is similar to that of open field cultivation; but it is a completely different proposition in comparison. In greenhouse it needs (1) high precision technology, (2) special management, and (3) high qualityinputs. A special crop husbandry is extremely necessary, integrating all these three aspects, for successful greenhouse cultivation.

Why special crop husbandry? – Ancestors of each and every crop of modern time once grew out of its own in wild, without any human intervention. Gradually it has been domesticated or brought under cultivation by progressive alteration of its natural growing and reproduction process. Even the genetic nature also altered gradually. Till recent past these development of domestication process has been restricted principally on reproduction, planting, nutrient supply, water supply, and plant protection aspects. Interestingly most of these aspects are still very much supplementary in nature, as a good percent of it is still dependent on nature and its growing system.Actually, we cannot confer any significant change, physically or genetically, in their adaptation against the natural elements like rain, sunlight, temperature, humidity, gas supply, etc. However, we try our level best with a compromising note on local climate.

Hence there is ample scope to go for complete alteration of their growing habit/ practices in relation to each and every aspect of the climatic elements. It is a very difficult job, because, for a small change in any individual aspect of plant growth, all the other aspects are affected. Thus, one has to make a proper and holistic balance of alteration of all the growth aspects for each and every individual domesticated plant, we call as crop.

The greenhouse technology is all about the controlling of ambient climatic factors to create a favourable ‘micro-climate’ for the crop growth. The magnitude of such control may differ from minimal to maximum. It may control single (like rain) to multiple aspects (like rain, temperature, humidity, sun-light, wind, carbon-di-oxide, etc in combination). It can simply be done by manipulating natural factors using the suitable/appropriate design of the greenhouse or can be done in complex form by using/installing different devices and packages (may be software) with necessary automation in a specifically designed greenhouse.

It is a vast subject and very difficult to have a thumb-rule for such climate control mechanism due to seasonal climatic variations and most importantly due to the inter-relation effect between each and every climatic factors. Thus, it should be given sufficient space to maneuver the mechanism designed for a specific greenhouse targeting a specific crop.

Ways to control these climatic factors in a greenhouse

There are two basic ways to control the climate inside greenhouse.

Primarily, through a suitable design of the greenhouse itself, the inside microclimate can be controlled, obviously up to a certain level. Through manipulation of the design, particularly the naturally ventilated system, the rain water, temperature, humidity, CO_2, wind, etc can be controlled up to a certain level in favour of the crop.

Secondarily, by introducing equipments, tools, devices, etc we can control the micro-climate of a greenhouse. In most cases, it can take care of a number of climatic factors, like temperature and humidity, sun-light and temperature, etc simultaneously to provide a crop-wise micro-climate inside.

Frequently we use both the basic controlling methods, in combination, to achieve the required climate control system in a particular greenhouse.

We have already discussed about the different climatic factors that affect the crop micro-climate. Now we will discuss the basic control mechanism of each and every climatic factors and the related technology that can be utilized for greenhouse.

5.1. Introduction

Back drop: Since the concept of greenhouse technology was introduced, metal and wooden structures were tried in different parts of the world. When greenhouse was brought in the tropical and sub-tropical areas, people tried bamboo as construction material for greenhouse instead of iron or wood. However, due to the non-standard character of bamboo, the standardization of design of bamboo greenhouse, as a model, was not possible. Actually all such designs were very much clumsy and not at all comparable to the well established models of greenhouse having metal or wood frame.

Hence it is an urgent call to establish a standard design of bamboo greenhouse that can efficiently compete with the other common & commercial greenhouses made-up of GI-pipes.

Innovation: This greenhouse is structured by matured, cured & treated bamboo instead of usual structural elements (GI/MS/wood). For that matter (1) innovated design and construction methods and (2) a new curing method has been generated. It is very tough to standardize the design of bamboo greenhouses, specifically due to the non-standardized nature of bamboo. Unlike GI/MS pipe etc, bamboos do not have the same dimensions and uniformity in size & shape (diameter/ width/thickness etc). Thus, in general, bamboo greenhouses are low in height and are of naturally ventilated type. However, there is still huge scope to work on design of bamboo greenhouse for different climatic situation to avail the benefits of its natural advantages and low cost.

Design and Construction of a greenhouse involves five distinctly different aspects viz. (a) Basic form or type, (b) structure/designs, (c) covering materials and its fixing, (d) foundation and constructional detail, and (e) crop-support, irrigation and drainage planning.

All the above aspects are interlinked. To have a clear idea, these individual aspects are discussed separately.

4.1. Basic Forms of Greenhouse

Before considering anything about construction, one should finalize the form of construction. There are different forms of greenhouses for different climatic and crop situations. These types of structures are planned according to the requirement of farmer/promoter and obviously according to the purpose. Now we will describe, in brief, some of the important form or type of greenhouses.

4.1.1. Greenhouse covered with transparent and impervious material

These structures are covered with water/rain impermeable transparent materials which allow necessary solar radiation for optimal growth of plants. Simultaneously it protects crops from temperature-fluctuation, rain, wind, and creates a favourable situation in respect of CO₂ and humidity. This covering is also used to prevent the re-radiation of heat energy and conserve the heat generated in daytime to raise night temperature inside.

3.1. Non-Climatic Factors

Apart from climate several other non-climatic factors has to be considered before selection of proper greenhouse technology, which are listed in the following text.

1. Location and selection of site: The ideal location for greenhouse cultivation is an area having moderate climate with high sunlight, low humidity and good natural drainage. It is better to avoid storm prone areas or it is a must to take necessary protection, like wind-break and shelter belt, in such areas. However, selection of site, where the greenhouse will be constructed, is the first consideration to select the proper greenhouse technology. The proper selection of site will also depend upon various non-technical factors, which are listed below.

2.1. What is Greenhouse Technology?

Greenhouse technology involves primarily the structural design that can take care of climate control mechanisms to create proper micro-crop-climate and secondarily it involves the technology needed for optimum growth and production of crop grown under this structure. Combination of these two aspects may be expressed as ‘greenhouse technology’.

So the ‘greenhouse technology’ may be defined as “The technology required to built a structure, covered fully, partly or porously for manipulating the inside climatic conditions, under which crops/plants can be grown with special measures”.

1.1. History of Cultivation

Prehistoric people lived as hunters and gatherers. About ten thousand years since now they unveiled the mystery of germination and engaged themselves in production of plant from seed. Since then it was practiced in the open field fully exposed to sun, rainfall, ambient temperature & humidity, etc. Gradually, with the development of society, they improved the package of practice and became accustomed to produce better crop in accordance with these natural conditions.

Backdrop of modern agriculture technology: Since the late 19^th century, population all over the world increased rapidly, which demanded more food production. This situation prompted crop production as a profitable business. New scientific inventions were incorporated in farming practices to increase the production per unit area (yield). On the other hand, repeated cultivation of same or similar crops in the same land, year after years, gradually reduced the productivity of soil. Hence, need arose for increase of crop yield through further improvement in farming technology.

First-phase development: The incorporation of ‘chemicals’ into the soil as plant nutrients(fertilizers) coupled with the use of ‘high-yielding varieties’ changed the scenario of crop production in the sixties of last century. This, along with ‘mechanization’, increased crop yield many-fold and helped to bring large areas under the plough. Countries, which developed these technologies, made good amount of money/profit from this development. Gradually, the rest of the world adopted or purchased these technologies particularly to meet up the rising demand of food in their respective country.

Subsequent problem: This systemof cultivation solvedthe food scarcity problem initially but use of chemicals, cultivation of similar crop over a large area etc. destroyed the agro- ecological balance. These technological developments, coupled with adoption of labour saving technologies, gradually created problems like gradual loss of soil health, lowering of nutrient-use-efficiency and subsequent yield. This invited severe attack of pests like insect, disease, weed and related social problem like unemployment.

8.1 INTRODUCTION

To implement a good GIS project, a well structured project design and management are essential. Well planned project will give fruitful result within the stipulated time. Project not completed in time will not incur more cost and also the time delay will add negative value to the project. Hence all the elements in project planning and implementation should be considered to have a desired result. Some of the issues are also present in GIS and they will be rectified in the next decade.

8.2 PROBLEM IDENTIFICATION

Any project is coming into reality due to necessity. If water scarcity is more in a hard rock region with sufficient rainfall, it is important to augment groundwater resource using rain water harvesting structures. It is important to build water harvesting structures like check dam, percolation pond in suitable locations so that groundwater recharge will be more. Hence a problem is identified and the project work may be carried out by a government or private organisation and the result is given to the government to implement the project. Likewise many area may require a project in GIS environment for planning. Once a project is created any development taking place can be added and GIS database is updated.

7.1 INTRODUCTION

Web technology revolutionised information technology and GIS of no exception. Analysis of maps available in internet through remote personal computer is called as web GIS. The term web is GIS synonymous with the term internet GIS. Most of the software vendors in the field of GIS have developed their GIS compatible to internet. The advantage of internet GIS is no need to own a GIS software in the personal computer. Maps available in a web site can be analysed for GIS functions as one could do with GIS in standalone personal computer. Applications of web GIS is not limited. Most of the governmental agencies, business people and others put their data in their server and the data could be analysed spatially for the users requirement. Internet mapping is simple, cost effective and reach vast audience.

Internet GIS is useful in field like civil engineering, government organisations, forestry, environment, goescience, utility planning etc.

6.1 INTRODUCTION

Besides simple analysis, GIS is useful to do advanced analysis like network analysis, spatial analysis, 3D analysis and modeling. Different softwares are available to perform such analysis and the above mentioned analysis is done in separate modules of the softwares.

6.2 NETWORK ANALYSIS

Network consists of well connected linear features. Roads, railway line, water distribution system, sewer line, streams are some of the examples of networks. These networks consists of nodes and arcs with designated directions and connection with other linear features. Networks are topology based with attributes for the flow of objects like traffic. Road network will be considered for explaining network analysis.

Road map is digitised with nodes and arcs. Signals, accidents are represented as points. Road is represented as line and two or more roads intersect at nodes. Attributes are added to the nodes and lines. Dynamic segmentation model is used for network analysis. It is built on lines of network. In road network analysis, attributes for travel time, one way street, two way street, right turn, impedance are added to the nodes and arcs. A link is the line running between two nodes. Link impedance is the cost of passing through the link. Travel time is different in links in cities due to varying traffic at different locations. Time taken to pass through a known length of link may give the cost but the travel time in a link is not uniform because of varying speed designated in the link as 20 km per hour and 30 km per hour. Hence it is important to consider the length of link and also the travel time. If the speed limit is 20 miles per hour for a length of 2 miles, then the travel time is 6 minutes (2/20x60 minutes). Also tuning in the network is considered. A road may have a maximum of 12 possible turns excluding U turns. There are right turn, left turn, straight way for each road. Also U turn is possible. This turning takes different time depending on the signal. Straight way takes less time but left and right turn may require some more time. If signals is available then signal time should also be taken into account. Fig 6.1 show the possible turns in a road.

5.1 INTRODUCTION

A GIS database without single error is reliable for decision making. There are various possible sources of errors in GIS. If an error is not removed during scanning, the final output will also have that error. Besides whatever the work has been carried on wrongly scanned map it will add to errors because the source map itself's erroneous. This is like garbage in garbage out proverb. If wrong data is taken for analysis it will only result in wrong output. Hence it is important to remove error at every stage of GIS work. It is important to locate the sources of errors so that due care may be taken while handling a project.

5.2 ORIGINAL SOURCES OF ERRORS

All the equipments which give attributed data and spatial data will give errors. Before going to field or before collecting data all the related instruments should be calibrated properly. Also the instrument should not cross the permissible error. Besides these while using data from diversified sources errors pertaining to those instruments are mixed to give a different result. When very good accuracy is desired data should be collected from high end equipments. Even if one adds the data from a comparbly less accurate instrument to the data of many accurate instrument is then the result obtained finally will not reliable enough. Global Positioning System (GPS) is available with mm accuracy to meters accuracy. Also surveying with suitable map projection and datum is important; otherwise the result will be wrong. Survey instruments posses some inaccuracy and when a person is using it he should have the accuracy over the instrumental like rain gauge, water level recorders which give attributed data which should be checked for instrumental inaccuracies and method of data collection before using it. Likewise satellite and aerial sensors miss some data and some error are inherent. Such errors should be removed before moving ahead. Errors are resulted due to map reduction, enlargement, data editing and computation method adopted. At the same mapping instruments also possess inaccuracies. When after certain interval a person is going for survey, the registered object may have been changed. Many new features might have come up. Hence the established control points are changed and if the wrongly placed control points are taken for survey then the result itself will be wrong. If proper resolution is not available in the instruments, then the instruments may not capture the minute details which are required.

4.1 INTRODUCTION

Database management system is a computer program to store, search, manipulate retrieve and give the result. Vast amount of spatial data are available and it is necessary to arrange them, store them for retrieval and analysis. Attribute data adds intelligent to GIS. Without database, a GIS will be just a Cad software. Cad softwares do not have database. GIS softwares have their own databases besides it has the potential to link with external database like Oracle, MS Access, MS Excel, Informix, INGRESS, Sybase and dbase. The data available in paper has to be digitally stored in a proper order. Previously the data were stored in a a flat file format where the data was stored without any structure. But to search and retrieve and analyse the database, database structures were developed. There are of 4 types of database structures namely Hierarchical, Network, Relational database and Object orientation.

Tables are made of rows and columns. Rows represent a map feature. Columns represents characteristic of map feature. Row is called a record or a tupule column is a field or an item. Table 4.1 is a table where rows 1, 2 and 3 represent the locations with the soil types. A column soil type represents various soil types.

3.1 INTRODUCTION

Geographic Information System handles large volumes of data. It is important to know the nature of data, instruments from which the data is collected and represented in computers. GIS data is either spatial or aspatial. Data is an important component in GIS. Digital data are available for some projects. but for many projects, input data may not be available. Now-a-days, data is supplied by many government, private organizations and also available on internet. If data for a particular project is not available, then the user has to collect the data from satellite imageries, GPS and other instruments and maps from various sources.

Spatial Data

All locations in the earth surface are spatial data. Location of a city, location of a river, location of a lake are represented in earth by their latitude or longitude in global coordinate system or as x,y coordinate in Cartesian coordinate system. Spatial data consists of location, shape and size in earth. A village boundary is represented as a polygon in map. The village is having certain shape of irregular polygon with definite area. As all these are mappable , they are called as spatial data. But name of the village, revenue of a village and description about a village and called as non-spatial or aspatial data.

2.1 INTRODUCTION

GIS is a tool that can be used in varied disciplines ranging from civil engineering to business. Remote sensing data is often brought into GIS to have a complete data set in many natural resource application areas. Full capability of GIS is not used widely. Many a times people use GIS only for digitising maps and to do simple query on maps. But it can also be used in modeling, simulation and forecasting, only then one may regard GIS technology is utilised to its full potential. Some GIS softwares handle simple problems for location based services while other complex softwares posses advanced modules to do all types of spatial, network and 3D analysis. Integration of softwares used in natural resources study are being interfaced with GIS to create scenarios.

Remote sensing and GIS technology is useful in the following fields:

1.1 INTRODUCTION

Geographic Information System (GIS) is the new emerging field and grows at very rapid pace. Now GIS is a billion dollar industry with applications in varied disciplines. At present, GIS is being used by professionals from various disciplines. In this decade, GIS is being used by experts who are good in GIS technology for various applications. The development trend indicates that GIS will be used by common man in near future and at the same time, advanced GIS analysis will be carried out by GIS experts.

Any technology is developed out of necessity and GIS is of no exception. When a large amount of data were available for water distribution systems, road network, sewer lines, telecom lines, electricity lines, gas pipe lines, state wise population, natural resources etc, it is important to store, maintain and retrieve the data for applications. It is not possible to manually browse through the large amount of paper records. Also even if the data is available in an unorganized way in the computerized environment, it is not useful. Hence if the data are referred to locations in earth surface and the data are stored in an organized way, it is possible to retrieve and analyse the data for applications. Hence the solution is GIS and developed today into reality. Developed countries are using GIS widely in many areas but developing countries are moving towards the development of GIS database for their resources.

Remote sensing, aerial photography, cartography, surveying and other field instruments for attribute data collection contributes to the data acquisition. Cartography, surveying, geography, geodesy contributes for mapping process. Disciplines like computer science and statistics, mathematics involved in processing and analysing data . Computer science and mathematics involved in storing the data structure.

GIS maps are intelligent. It has many advantages compared with paper map in this digital age.

Spatial data means data which are referenced to earth. Maps, satellite imageries, aerial photographs are example of spatial data. Attribute data which are attached to spatial data are called as aspatial data or non-spatial data.

If these data are brought into GIS then it is stored in a standard format, it is possible to update, share, retrieve, manipulate and analyse quickly. Much of the time and money is saved in case of reproduction and better decisions could be made

Abstract

The use of plants for treating diseases is as old as the human species. Popular observations on theuseandefficacyof medicinal plants significantly contribute to the disclosure of their therapeutic properties, so that they are frequently prescribed, even if their chemical constituents are not always completely known. Medicinal plants have therapeutic potential due to the presence of natural antioxidants functioning as reducing agents, free radical scavengers and quenchers of singlet oxygen. Majority of their antioxidant activity is due to bioactive compounds viz. flavones, isoflavones, flavonoids, anthocyanins, coumarins, lignans, catechins and isocatechins. They have been recognized to possess several medicinal properties (diuretic, expectorant, laxative, anti- bacterial, anti-pyretic etc.) and have been effectively used in the indigenous systems of medicine in India and other countries. Apart from the traditional use, a number of beneficial physiological effects have been identified by extensive studies. Among these are their beneficial effects on lipid metabolism, efficiency as antidiabetics, ability to stimulate digestion and to inhibit platelet aggregation, antioxidant, antilithogenic and anti-inflammatory potential.In this chapter an attempt has made to elucidate and understand the chemical and medicinal properties of Stavar and Safed musli those are using as medicine. These may also use as ingredients for preparation of herbal food products.

Abstract

Fats and oils are one of the five essential ingredients of human diet and the others are protein, carbohydrates, minerals and vitamins. The oil seeds are major source of edible in world. Oils and fat form an important constituent of human food. Lipid metabolism generates many bioactive lipid molecules, which are fundamental mediators of multiple signaling pathways and they are also indispensable compounds of cell membranes. Many people in developing countries, especially children under five years of age suffer from acute or chronic protein and energy shortages. There is definitely a need for food production to keep pace with the increase in the number of the world’s population. Oilseed and nut should be properly dried before storage, and cleaned to remove sand, dust, leaves and other contaminants. All raw materials should be sorted to remove stones and moudly nuts. Some moulds, especially in the case of groundnuts, can cause aflatoxin poisoning.

Introduction

Oil has been a vital part of people’s regular dietary consumption all over the world and its usage has been found to increase several folds over the decades. The importance of using the appropriate oil for cooking goes a long way in affecting the consumer’s health. Improper methods of oil-aided cooking can lead to cardiovascular diseases and increased cholesterol in the blood (Kumar et al., 2018). There is definitely a need for food production to keep pace with the increase in the number of the world’s population. In order to achieve these national development strategies in many based economy tropical countries on agriculture and biased now towards increasing diversity of food products and consumer in order to alleviate malnutrition and pressure to strengthen and expand based industries on agriculture to ensure that their products are both healthy and safe. Oils and fats for food have used a variety of other applications since prehistoric times, and were easily isolate the source of the fats and oils found useful because of its unique properties.

Abstract

Herbal Burfi was development with various types of milk viz., Buffalo (6% Fat), Cow (4% Fat) and mixed milk (5% Fat) and different levels of sugar i.e. 20, 25, 30 and 35 per cent (weight basis of khoa). Each sample was fortified with 5g satavar and safed musli powder. Other minor ingredients like Almonds, Cardamoms, Cashew nuts, Pistachio nuts, etc were mixed thoroughly and after preparation herbal burfi was allowed to set at room temperature (20- 25_oC) for two hours. Physico-chemical (acidity, pH, fat, protein, lactose, sugar, ash and total solids), microbial (total plate count, coliform count, yeast and mould count) quality and sensory attributes of the herbal burfi were evaluated. The data of experiments were statistically analyzed to compare significance effects of various factors by applying factorial Randomized Block Design (fRBD) with the help of OPSTAT software and ANOVA.

Abstract

Food texture is one of the most widely measured quality attributes during postharvest handling, processing, and consumption. Given the subjectivity in human perception of food texture, texture measurement remains a complex exercise and thus presents both a charm and challenge for researchers and industry practitioners. For fresh foods such as fruit and vegetable, textural properties such as firmness are widely used as indices of readiness to harvest (maturity) to meet requirements for long term handling, storage and acceptability by the consumer. For processed foods, understanding texture properties is important for the control of processing operations suchasheating, frying and drying to attain desired quality attributes of the end product. Texture and viscosity measurement is one of the most common techniques and procedures in food and postharvest research and industrial practice. Foods are complex systems exhibiting various degrees of elasticity, viscosity, and plasticity. Because of its complex structure and mechanical behavior, objective measurements of food texture may be influenced by a variety of test conditions, including rate of loading, the magnitude of deformations imposed upon the material, geometry of the loading surface, and localized yielding within the product tested. Various approaches have been used to evaluate the sensory attributes of texture in foods. However, the high cost and time consumption of organizing panelists and preparing food limit their use, and often, sensory texture evaluation is applied in combination with instrumental measurement.

Humankind has always been a perceptive feel for rheological testing, e.g. in physical and visual evaluations of material properties such as hardness, stiffness, flexibility, and viscosity, and their relation to end-use quality characteristics. People often naturally measure the quality of solid foods by gently squeezing them, or liquid viscosity is measured by gently rotating the liquid in its container. These intuitive measurements gradually became formalized into quantitative descriptions of material properties.

Rheology can be defined as the study of how materials deform, flow or fail when force is applied. The name is derivated from Greek word: rheos, meaning the river, flowing, streaming. Therefore rheology means “flow science”. Rheological investigations not only include flow behaviour of liquids, but also deformation behaviour of solids. Normally, to measure rheological properties, the material is subjected to a controlled, précised and quantifiable distortion or strain over a given time and the material parameters such as stiffness, modulus, viscosity, hardness, strength or toughness are determined by considering the subsequent forces or stresses (Dobraszczyk and Morgenstern, 2003). The term rheology was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, from a suggestion by a colleague, Markus Reiner (Steffe, 1996)

Abstract

Physical properties of food are aspects such as colour, structure, texture, rheology and interfacial properties, and composition. We have a range of instrumental methods for objectively characterising and measuring food structure and physical properties. These are useful for applications such as new product development, benchmarking, reformulation and specification.

Colour

Consistent and accurate measurements of the colour and visual appearance of food products is extremely important. Various methods are available for colour measurement, allowing a wide variety of sample types to be measured. Colour measurement results are typically provided on the CIELAB scale. Others are available on request.

Abstract

In India, the allium groups (onion and garlic) are important bulb crops for home consumption as well as sources of income to many peasant farmers in many parts of the country. The garlic bulbs are valued for their flavor and have wide applications in food and their antimicrobial, antifungal, insecticidal and antioxidative properties. The engineering properties of garlic bulb, clove and skin plays important role in the planning of various post-harvest operations like drying, sorting, grading, bulb breaking, peeling and designing the process equipments like bulb breaker, clove separator and peeler. The aim of this chapter was to study the engineering properties viz., physical, mechanical, aerodynamic and frictional properties of garlic bulbs, and cloves in both peeled and unpeeled form.

Introduction

India is rightly the spice bowl of the world. India has the largest domestic market for spices in the world. Indian spices are the most sought-after globally, given their exquisite aroma, texture and taste. Garlic (Allium sativum L.) is a world’s favourite, versatile horticultural commodity consumed for culinary, medicinal and antimicrobial purposes and is being cultivated for over 5000 years. The most important part of the garlic plant is the compound bulb. Each bulb is made of 6-26 cloves and is wrapped in a white papery sheath. Some varieties have a radish or purplish sheath. The bulbs are valued for their flavour, command extensive commercial importance because of their wide application in food and pharmaceutical preparations. Garlic is still probably nature’s most powerful medicinal plant to us today. It is recognized to have remarkable preventive and curative abilities. Garlic is mainly used aromatic spices and pickles as it has digestive, carminative and anti-rheumatic properties. It is being used in ayurvedic formulation since a long for curing lungs, healing the intestinal ulcer and checking muscular pain and giddiness.

Abstract

During present investigation a comparative study was done to see the effect of storage on physical properties of tomatoes (Lycopersicon esculentum Mill) packed in HDPE and stored under ambient temperature. Four varieties of tomatoes taken for current investigation were Badshah, Himshikhar, NS-524 and Raja. From the studies it was clear that TSS increased gradually during storage duration for entire tomato varieties due to loss of some moisture from tomatoes. Variety NS-524 shows maximum shrinkage among all during observation period.

Abstract

The chapter aims at introducing selected physical properties of food and biological materials in food process and application in the field of food technology. These physical properties of food are not only used for designing of food equipments but can also maintain the nutritive value of food to a greater extent during processing in these equipments.

Introduction

The investigation of food engineering is spotlighted on the inspection of equipments and system used to process food materials on a commercial scale. Building of system for food materials can be efficient if two factors are known, the nature of the food product and what happen to the food during its processing. Food materials are organic in nature and it has a certain kind of qualities which recognize them from other processed food product. Since food materials are organic in nature, they have (a) shapes usually found in normally non regular; (b) properties which differ from other food products; (c) heterogeneous arrangement; (d) properties are varied due to climatic conditions, ripening conditions, etc. and (e) several other factors such as (e) influenced by chemical changes, moisture content variation and enzymatic movement. Managing food materials with these remarkable attributes requires extra thought, for the most part by implication and extra sources or reasons for different varieties. The attributes of a food material that are autonomous of the on looker, quantifiable, can be measured, and characterize the condition of the material (yet not how it accomplished that state) are considered as its physical properties.

Introduction

Sem (Dolichos) bean, Hyacinth bean or Field bean is one of the most ancient crops among cultivated plants. It is a bushy, semi-erect, perennial herb, showing no tendency to climb. It is mainly cultivated either as a pure crop or mixed with finger millet, groundnut, castor, corn, bajra or sorghum in Asia and Africa (Maass et al., 2010). It is a multipurpose crop grown for pulse, vegetable and forage. The crop is grown for its green pods, while dry as well as fresh green matured seeds are used in various vegetable food preparations, as most of the nutritive value is concentrated in the seeds. FAO website reports that Dolichos lablab (field bean) is a dual purpose legume. It is traditionally grown as a pulse crop for human consumption in south and south-east Asia and eastern Africa. Flowers and immature pods also used as a vegetable. It is also used as a fodder legume sown for grazing and conservation in broad acre agricultural systems in tropical environments with a summer rainfall. Also used as green manure, cover crop and in cut and carry systems and as a concentrate feed.

Abstract

Quality assessment of fruits and vegetable before marketing and processing is an essential task. Various destructive and non-destructive methods have been investigated to achieve this goal. Among the several prevalent noninvasive methods, optical properties measurement methods also promotes for nondestructive quality inspection of fruits and vegetables. The optical properties of biological tissue are, therefore, very importance important for getting sample information and data quantification of the inside of the material. The main goal of this chapter is, thus, to introduce fundamental concept of optical properties, its principle and application in fruits and vegetables. The discussion of electromagnetic radiation for better understanding of the nature of light has also been explored.

Abstract

Thermal properties of food are its ability to conduct, store and lose heat. These properties are inherent in food processing and preservation practices. Thermal properties are important for modelling processes, engineering design of processing equipment, sterilization and aseptic processing. Important thermal properties are thermal conductivity, specific heat and thermal diffusivity. These properties depend on chemical composition, water fraction and temperature.

Introduction

Thermal properties are involved in almost every food processing operation. It is essential to have knowledge of thermal properties of foods which is important in analysis and design of various food processes and food process equipment involved in heat transport. Thermal properties of food are greatly depending on composition, temperature and density of food. Thermal properties required for heat transfer calculation include specific heat, enthalpy, thermal conductivity and thermal diffusivity. Thermal properties of foods are related to heat transfer control in specified foods and can be classified as thermodynamic properties (enthalpy and entropy) and heat transport properties (thermal conductivity and thermal diffusivity). Thermo physical properties not only include thermodynamic and heat transport properties, but also other physical properties involved in the transfer of heat, such as freeze and boiling point, mass, density, porosity, and viscosity. These properties play an important role in the design and prediction of heat transfer operations during the handling, processing, canning, storing, and distribution of foods.

Abstract

The electromagnetic processing instruments such as microwave is very commonly used at house hold level, hence understanding the behavior of food as well as factors affecting its dielectric properties becomes important. Dielectric properties (DEP) play an important in electromagnetic processing of food products and mainly depend upon the moisture content, physical properties, composition, temperature and power applied. Different methods have been used to determine the DEP of food material including parallel plate, coaxial probe, resonance cavity, transmission line and free space method. The selection of these methods is again based on several factors such as type of materials, accuracy of measurement, the scope of the research, frequency range, availability of equipments and resources. Present study thus summarizes the importance of DEP of food, influencing factors and the different measurement techniques.

Abstract

Rheological properties of dough from different flours are very important to know about the kneading and modeling process especially for development of bakery products. Rheological testing is helpful to examine the structural and fundamental properties of dough. The basic principle underlying evaluation of rheological properties are mechanical behavior of the dough, in conjunction with the physical structure of the dough, the molecular structure of the protein continuous phase in the dough and with chemical reactions of functional groups. This chapter presents some of the methods currently used in bakery industry for determining the rheological characteristics of the flour and the dough. The instruments such as Farinograph, Mixograph, Extensigraph, Alveograph and Amylograph, which are used for the measurement of dough rheological properties (due to visco-elastic behavior of dough) were described.

Abstract

The frictional properties such as coefficient of friction and angle of repose are very important in designing of storage bins, hoppers, chutes, conveyors, harvesters and threshers etc. Angle of repose is the angle made with the horizontal at which the material will stand when piled. The angle of repose is also important in designing the equipment for mass flow and structures for storage. The static angle of repose (b) was determined using an open-ended cylinder of 150 mm diameter and 250 mm height. The higher the moisture content, the higher the cohesion between the seeds. In terms of flow ability, the seeds are heavier and the inertia to move is increased. Coefficient of internal friction is the frictional resistance of seeds with each other. Coefficient of external friction is the frictional resistance between the seeds and the surface. The rolling resistance is directly proportional to the weight of the rolling object and to the coefficient of rolling resistance which is dependent on the rigidity of the supporting surface and indirectly proportional to the effective radius of the rolling object. The air velocity at which an object remains in a suspended state in a vertical pipe under the action of the air current is called terminal velocity of the object.

Abstract

The research work was conducted on the moisture dependent physical properties of kidney bean (White speckled kidney beans) were analyzed. Length, width, thickness varied between 1.53-1.90, 0.79-0.94, 0.58-0.76 cm for kidney beans, respectively. Arithmetic mean diameter and geometric mean diameter were 0.96-1.19 and 0.88-1.11 cm₂, respectively. Volume, Sphericity and surface area ranged between 0.44 -0.87 cm₃, 0.57-0.60 and 2.91-4.68 cm₂ for white speckled kidney beans, respectively. The kidney bean was soaked in normal water with initial moisture content 14.22 % (db) upto 270 min and attained the final moisture upto 83.23 % (ab).

Abstract

Mean values of mass of 1000 pea seeds, volume, bulk density and true density were found 329.501 g, 0.2 ml, 0.275 g/cm₃ and 0.304 g/cm₃ respectively. Average values of angle of repose, sphericity, porosity and moisture content were found 24.7, 0.926 %, 9.528 and 80.96%, respectively.

Abstract

Food processing involves the transformation of raw animal or plant materials into consumer-ready products, with the objective of stabilizing food products by preventing or reducing negative changes in quality. Without these processes, we would neither be able to store food from time of plenty to time of need nor to transport food over long distances. Food processing has also gained its importance in the wide variety of diet among people throughout the globe and availability of exotic food items at various places. Processing of food items enhance the taste, flavor and aroma of the food thereby increasing the overall chances of its acceptability among the masses. So, it is essential to determine and recognize the database of physical and engineering (aerodynamic and mechanical) properties of these agricultural products because these properties play an important role in designing and developing of specific machines and their operations such as sorting, separating and cleaning, also to determine the optimum in seed metering device in pneumatic planter and precision sowing machine to suite every size of these grains.

Abstract

Multi-commodity flours were prepared by blending rice flour, mung flour and potato flour with wheat flour in ratios of 0:0:0:100, 5:5:5:85, 10:10:10:70 and 15:15:15:55, respectively and packaged in glass jar, high density polyethylene and aluminium flexible packaging for biscuits development. The standardized formulations for biscuit had ingredients as 100 g flour/multi-commodity flour, 45 g sugar, 45 g hydrogenated fat, 1.25 g sodium bicarbonate, 1.25 g baking powder and 1.0 g curry leave powder. The biscuits were baked in convective baking oven at 180 > C for 10-15 min till baked. The well baked biscuits were removed from the oven, cooled to room temperature, packaged and stored under ambient condition. The physical quality (Mass, thickness, diameter, spread ration percent spread and bulk density), of biscuits were analyzed just after preparation under ambient condition. Results were also reported that the spread ratio of multi-commodity flour biscuits increased with decrease in the incorporation of wheat flour in multi-commodity flours. It is clear that spread ratio is mostly influenced by the diameter and thickness of biscuits.

In 1920, a 30-year-old Czech writer Karel Èapek, wrote a play called “R.U.R.” (Rossumovi Univerzální Roboti or Rossum’s Universal Robots). For this dystopian work about a bad day at a factory populated with sentient androids, Èapek called the androids “roboti”, as suggested byhis brother Josef, a painter and writer. It was premiered in Prague on 25^th January, 1921.

Èapek was admired for his opinions:

My dear Miss Glory, Robots are not people. They are mechanically more perfect than we are, they have an astounding intellectual capacity, but they have no soul.

But surprisingly he was keen on gardening!

EAAMs (Electric Agricultural Aerial Machines) have emerged from drones used for both aerial filming, as toys and even as racing units. A Price water house Coopers’ study revealed that the global market for drone-powered business solutions was valued at $127.3 billion in 2016. For agriculture, prospective drone applications in global projects were valued at $32.4 billion. Stelios Kotakis and colleagues at market research firm IHS Markit projected that there would be around 400,000 shipments of drones to firms in the agriculture and forestry sectors in 2017. The Food and Agriculture Organization (FAO) of the United Nations projects that by 2050 humanity’s ranks will likely have grown to nearly 10 billion people. Farmers will need to produce more with less, while preserving our environment for future generations. And society has a duty to help them achieve this. Although agriculture is perceived as a traditional economic sector, precision agriculture technologies have already boosted crop yields significantly in the last decades. The same study forecast that agricultural consumption would increase by 69% from 2010 to 2050.

This chapter traces the history of the electric quadcopter commonly known as the drone, prior to its use in agriculture.

As long ago as 1493, the versatile Italian Leonardo de Vinci, painter, sculptor, machine designer often inspired by his observations of Nature, made a sketch in one of his little notebooks of a screw-like machine next to which he wrote in his mirror-handwriting:

If this instrument made with a screw be well made – that is to say, made of linen of which the pores are stopped up with starch and be turned swiftly, the said screw will make its spiral in the air and it will rise high.¹

Four centuries later, in 1863, the Viscount Gustave du Ponton d’Amécourt, President of The Society for the Encouragement of Aerial Locomotion by Means of Heavier than Air Machines, published a forty-page monograph in Paris, entitled “The Conquest of the air by propeller. Account of a new system of aviation.” In this he took the Greek words helico and pteron, meaning “spiral” and “wing”, and combined them into the word hélicoptère (helicopter). D’Amécourt and his friends were among those very few who were passionately convinced that the future of flying was with heavier-than-air machines. To prove their point, having built a fragile flying machine model driven by clockwork springs, they watched it ascend vertically for a few seconds to a height of less than 3 metres (10 feet), only to crash back to the ground.

The 21^st century dawned with interest in the potential of electric agricultural machines. Beginning in 2000, a concept study, MELA Mobile Elektrische Leistungsund Antriebstechnik Mobile (electric power train technology)supported by universities and organizations in Germany as well as Fendt Agricutural Company (AGCO) showed a possible solution on tractor electrification with electric driven auxiliaries as well as electric CVTs and implement electrification. In 2003 the University of Hohenheim developed an electric combine harvester called Magda. With the introduction of a 42 VDC power supply system, the range of small rotational drives and servo motors could be covered. They showed that if more power had to be transmitted, threephase alternating current should be used since threephase machines had a large speed range and a large range of constant power.

During the first years of the century, longestablished transport manufacturers have been quick to see the environmental advantage of electric propulsion, be it with batteries, hybridelectric or fuel cell. With airliners, Boeing, Airbus and Tupolev quickly saw the advantage. With motorcycles, names such as HarleyDavidson, Curtiss, Ducati, Saroléa and Royal Enfield have positioned battery packs between two wheels. With trucks, Daimler, Toyota, Cummins, Peterbilt, DAF, Volvo, Leyland, Kenworth, and Isuzi, among others have taken the electric route. With buses, Alexander Dennis, Scania, Volvo, New Flyer, Van Hool, DAFVDL, Blue Bird, Heuliez, Rampinican carry their passengers more silently. It therefore seemed only logical that traditional agricultural machinery builders should make the same transition. The first to do this was John Deere, established in Moline, Illinois in 1837.

In 1920, although electric vehicles were not used on the American farms about 5,000 electric industrial trucks were produced by 12 American manufacturers, while estimates of the total fleet ranged from 6,000 to 15,000, most of them built during the war. Most used an exchange charging system. Among the manufacturers seen in and around cities and towns were the Commercial Truck Company, the Lansden Company, the Walker Vehicle Company (now owned by Commonwealth Edison), the Ward Motor Vehicle Company, the Steinmetz Electric Motor Corporation, Walter Motor Truck Company, and the Baker R L Corporation.One step away from agriculture, Charles A. Ward of New York City, was head of his family’s baking company, made up of the Mackey Company, the Ward Corby Company, the Ward Bread Companyand the Ohio Baking Company of Cleveland. In 1911, Ward had decided to replace his horse-drawn delivery vehicles with electric trucks, thus doing away with the unsanitary stable hitherto part of or adjacent to bakery.¹

Alongside this, the challenge of using stationary electric agricultural machines continued to be met. Two innovations which entered into dairy farming were the milk cream electric centrifugal separator and the surge milker. The Babson brothers (Henry, Fred and Gus) of Chicago were friends of and dealers for electrical battery inventor and entrepreneur Thomas Edison, and importers of Belgian-made Méllote separators. In 1916, the Babsonsproduced their own Pine Tree milking machine. While the overall design was similar to others, the electrically powered Pine Tree Pulsator outperformed any other pulsator made. These machines were powered by a 32-volt Delco system with 12 batteries near the barn. Pine Tree Pulsators were simple enough that the farmer could maintain them himself. The Pine Tree Pulsator was patented in 1921. The problem with this unit was that it was difficult to keep clean.

The domestication of oxen in Mesopotamia and the Indus Valley Civilization, perhaps as early as the 6th millennium B.C. provided mankind with the draft power necessary to develop the early plough into the larger, animal-drawn true ard (or scratch plough). Some of the earliest evidence of ploughing from around 2800 B.C.was found at the Indus Valley site of Kalibangan. Subsequent archaeological finds in Prague, Czech Republic, push the oldest known ploughed field even further back to 3500-3800 B.C. All food produce was planted and harvested by hand: seeds were scattered by hand and planted grains were brought from the field to be threshed on the dooryard. Milking a small herd of cows or goats was also done by hand. This continued for centuries. Then man discovered electricity.

In 1746, just a few years before Benjamin Franklin of Philadelphia sent a kite to catch lightning in a storm, a Doctor von Maimbray gave talk to the Royal Society of London where he described his experiment of electrifying the myrtle bush (Morella cerifera) which then put forth new branches in October, something which had never happened before. This news inspired others in Europe to carry out similar experiments. In 1749, Abbot Jean Antoine Nollet of the Royal Academy of Sciences in Paris France, inventor of the electroscope, published a pamphlet on “The Harmful Effects or Advantageous of Electrical Phenomena on Plants.”¹Isolated experiments continued until in 1783 Father Pierre Bertholon de Saint-Lazare of Montpellier published “About the Electricity of Plants”, a work in which he dealt with the effect of atmospheric electricity on plants, taking in their medicinal and nutritive-electrical virtues and but in particular the practical means of applying it usefully to agriculture.²He even built an electro-vegetometer, a device for collecting atmospheric electricity to distribute it in the soil and then to the plants, but he met with little success. Bertholon also conceived of subjecting plants to “electric rain” by connecting a large syringe to an electric source. A gardener, standing on a slab of insulating material in a wagon, carried a sprinkling can electrified by means of a wire leading to a static machine. “By means of this process, strange for the times, the good Abbé Bertholon, who was considered something of a sorcerer, obtained lettuces of an extraordinary size.”3

In this Chapter the precision farming/ Agriculture is discussed along with its steps of implementation. It also includes how artificial Intelligence plays role to perform precision farming/ agriculture in various way along with its scope, limitation and challenges.

Introduction

The primary source of livelihood is agriculture in India, where two thirds of India’s population, services and the private sector account for the remainder. Agricultural land accounts for about 43 percent of the geographical area of India. In earlier days, India was largely dependent in terms of food imports, but over the years, the country’s production of grain and seeds was self-sufficient, and this effort led to the formation of the Green Revolution. In fact, there was strong effort to achieve food self-sufficiency. This trend has continued up to now and continuous improvements have occurred. Precision agriculture or precision farming means the right thing to do, in the right way, on the right place and at the right time. Precision agriculture is expected to suit the agro-climate activities to improve application precision. Farming land has declined a bit in the last 40 years but the number of farmers has increased. According to the 2010–11 Agriculture Census, a total of 138.35 million operating holdings were estimated (single farmers) and 159,59 million hectares were covered by operations.

Precision agriculture is a management technique that collects, processes and analyzes temporary, spatial and individual data and integrates this with other information in order to support management decisions based on an estimated variability to enhance efficiency of use of agricultural production resources, productivity, quality, profitability and sustainability. Precision Agriculture manages every input of crop production (fertilizer, specifically found calestone, herbicide, seeds, insecticide, etc. Reduce waste, boost income and maintain efficiency Place. Precision Agriculture adapts soil and crop management carefully to suit the different field conditions.

Introduction

The conventional approach of the human person for plant classification is comparing the color and shape of the leaves, but by using Artificial Intelligence analysis can provide quicker and more detailed results by analyzing the morphology of the leaves and provides more details about the leaf properties. Species Recognition has been a very important part of agriculture and there are thousands of species in plants which can be identified by a single person and even if it does so It will take a huge lot of time to do it.

In this chapter we will discuss and built a project related to identify species in flower with an image. In this project we will be using Artificial Intelligence different branches like machine learning, deep learning and computer vision to build such an amazing project. So, let’s begin

Introduction

In agriculture, plant diseases have always been a major problem, as they cause crop quality to decrease, resulting in yield. Plant disease has a range of effects from minor symptoms to serious damages in whole crop areas, which lead to high financial costs and significantly impact the agricultural economy, particularly in developing countries dependent on a single crop or on a few crops.

Various approaches have been developed to detect disease in order to avoid significant losses. Causal agents have been precisely defined by methods developed in molecular biology and immunology. However, for many farmers these techniques are inaccessible and require detailed knowledge of the field or substantial time and energy to be used. According to the United Nations Food and Agriculture Organization, most farms in the world are small and family-owned in developed countries. Such families provide food for a significant proportion of the population of the planet. However, hunger and food insecurity are not rare and there is restricted access to markets and services. For the above reasons, a great deal of work has been undertaken in order to establish methods that are sufficiently reliable and available to most farmers. Where Plant disease is an essential factor contributing to a major decline in plant production quality and quantity. Plant disease identification and classification are a significant role in improving plant production and economic development.

In this chapter of machine learning algorithms we will cover the basic algorithms of machine learning with their implementation using dataset and discuss their pro’s and cons of algorithms for better understanding and how to use them in any project or with any dataset to get an correct result which can useful for research or study.

Key Component

We defined a data set composed of audio, images and binary labels that provided an understanding of how we could train a model from snippets to classifications. This sort of problem is one of many kinds of machine learning problems when we try and predict a specified unknown label given known inputs, provided that a dataset of examples for which labels are known is called supervised learning. Let’s discus what are the major key components we have to get there

In this chapter we will cover all the basics libraries and some frameworks of machine learning, deep learning and computer vision. We will discuss all about their use with an example and instruction which will states the commands to install to those libraries for building any project in our system. So let’s begin

What is a Library?

Library is an aggregate of features and methods that allow you to take many actions without getting your own code written.

For instance, the libraries that you have to know are if you work with data, numpy, scipy, pandas, etc. They have very simple data processing functions that save you time for small tricks.

In this chapter we will talk about the tools which are required to make project in artificial intelligence. All this bellow discussed tools are uses python programming language for making any project in any respective field. We have discussed about how anyone can install and use the tools to built a real time project in artificial Intelligence.

Using Python IDE

To download and install Python visit the official website of Python https://www.python.org/downloads/and choose your version. We have chosen Python version as per requirement all the codes in this book were on python version 3.6 as you can see in the Fig. 7.1.
