1. Arithmetic operators

2. Comparison/relational operators

3. Assignment operators

4. Logical operators

5. Identity operators

6. Membership operators

7. Bitwise operator

12.1 Introduction Basic Functionality

By now, we learnt about the three Pandas DataStructures and how to create them. We will majorly focus on the DataFrame objects because of its importance in the real time data processing and also discuss a few other DataStructures.

12.2 Series Basic Functionality

Let us now create a Series and see all the above tabulated attributes operation

Example

import pandas as pd

import numpy as np

#Create a series with 100 random numbers

s = pd.Series(np.random.randn(4))

print(s)

Its output is as follows:

0 0.967853

1 -0.148368

2 -1.395906

3 -1.758394 dtype: float64

13.1 Statistical Functions

Statistical methods help in the understanding and analyzing the behavior of data. We will now learn a few statistical functions, which we can apply on Pandas objects.

Percent_change

Series, DatFrames and Panel, all have the function pct_change(). This function compares every element with its prior element and computes the change percentage.

Example

import pandas as pd

import numpy as np

s = pd.Series([1,2,3,4,5,4])

print s.pct_change()

df = pd.DataFrame(np.random.randn(5, 2))

print(df.pct_change())

14.1 Basic Plotting: plot

This functionality on Series and DataFrame is just a simple wrapper around the matplotlib libraries plot() method.

Example

import pandas as pd

import numpy as np

df = pd.DataFrame(np.random.randn(10,4),index=pd.date_range(‘1/1/2000’, periods=10), columns=list(‘ABCD’))

df.plot()

Its output is as follows:

If the index consists of dates, it calls gct().autofmt_xdate() to format the x-axis as shown in the above illustration.

Python has emerged as one of the most popular and versatile programming languages in the contemporary world of computing. Developed by Guido van Rossum and first released in 1991, Python was designed with a clear emphasis on simplicity, readability, and ease of use. Its syntax closely resembles natural language, making it an ideal choice for beginners as well as experienced programmers. Over the years, Python has evolved into a powerful, high-level language that supports multiple programming paradigms, including procedural, object-oriented, and functional programming. One of the defining features of Python is its readability and clean structure, which allows developers to write clear and concise code. Unlike many other programming languages that rely heavily on complex syntax and punctuation, Python uses indentation to define code blocks, promoting better organization and reducing the likelihood of errors. This design philosophy not only enhances code clarity but also encourages good programming practices,

R packages include functions, codes and sample data. The functions used in R are contained in packages. A package in R contains several functions which are related to some particular type of job. A package conatins at least one function and there is no maximum limit to the no. of functions in a package. The set of packages in R which are set by default in the software is called base package. It contains a lot of commonly used functions. The packages in R are stored under a directory called “library” in the R environment. The packages get installed by default while installing R in the computer. Also more packages can be added later on after installation, when required for some specific purposes. The base packages are available by default when we start using R. But the other packages which are already installed while installing R have to be loaded while using R. These packages can be viewed in the package window by clicking on package. To install the package we have to click on install menu in the package window and then write the name of the package.

The packages can also be installed by using the function install.packages(“abc”) where abc is the name of the package to be installed.

Once a package is installed, it remains in the hard disk of the PC/laptop. But the package will have to be called for use in the current R session. The package once installed can be loaded for use in the current R session by checking the box near the name of the package displayed after clicking on the install menu in the Files/ Plots/Packages/Help window. The package can also be loaded by using library() function. The command will be library(“abc”) where abc is the name of the package. The loaded package remains in the memory for the current R session. Once we quit the R session, the installed package has to loaded again if needed.

Rabies is an ancient, dreadful disease known to mankind from the vedic ages. It is a zoonotic disease caused by Rabies virus, genus Lyssavirus family Rhabdoviridae, affecting all mammals including man. The WHO categorizes rabies as a neglected zoonotic disease that causes around 59,000 human deaths globally annually after onset of symptoms. It is a vaccine preventable disease reported from over 150 countries and territories barring the island nations like Australia, Brunei, Japan, Maldives, New Zealand, Papua New Guinea, Singapore, Timor Leste and the Pacific Island Countries. The Indian islands of Andaman Nicobar and Lakshadweep are rabies free so far.

On the other hand, Africa and Asia has the highest burden of human rabies including South-East Asia: Bangladesh, Bhutan, DPRK, India, Indonesia, Myanmar, Nepal, Sri Lanka, and Thailand. The Asia Pacific region having 60% of the world’s population includes the world’s most populous countries – India and China. Asia alone shares almost half of the global rabies deaths annually.

Introduction

One of the remarkable advancements in veterinary medicine recently is the application of interventional cardiology techniques to treat various congenital heart diseases. In dogs and cats, congenital heart diseases can be treated much more easily and with fewer complications using minimally invasive interventional approaches, rather than through traditional open-heart surgery. Among congenital heart diseases, treatment options are available for conditions such as PDA (Patent Ductus Arteriosus), AS (Aortic Stenosis), PS (Pulmonic Stenosis), VSD (Ventricular Septal Defect), ASD (Atrial Septal Defect), extrahepatic shunt, and stem cell applications. These diseases often cannot be significantly improved by medical treatment alone, making the use of the aforementioned interventional techniques essential for effective management.

I. CHALLENGES TO CYBERSPACE

The problems and prospects of copyright and information technology need to be deliberated in the context of present day jurisprudence. The subject is referable to the extensive use of information technology all over the world which has resulted in enhanced efficiency, effectiveness and optimum use of resources. The copyright law is concerned with the negative right of preventing copying of the physical material in the field of literature and arts. Trade and Merchandise Marks Act protects the patent, trade mark and design giving the registered proprietor an exclusive right to the registered material. The prohibition contained in rights in patent and copyright extend to the unauthorised manufacture or reproduction, so long as the exclusive right rests. Copyright has been held to be not the mere creature of the statute but a natural and civil right. The moral basis of the copyright is that the man is entitled to the fruits of its mental faculties as much as he is entitled to the fruits of his mechanical labour. The law rests on the English Commandment - thou shall not steal. It does not permit one man to make a profit and appropriate himself what has been produced by the labour, skill and capital of another. Blackstone in his commentaries Vol.II at page p.406 has stated:

There is still another aspect of property and this is the right which an author may be supposed to have in his own original literary compositions: so that no other person without his leave may publish or make profit of the copies. When a man by the exertion of his rational powers has produced an original work, he seems to have clearly a right to dispose of that identical work as he pleases and any attempt to vary the disposition he has made to it appears to be an invasion of that right.

I. INTRODUCTION

Procedural remedies for the infringement of one’s right are not enough by themselves unless they result in some reliefs of substantive nature whereby it can reasonably be said that these reliefs, temporary or permanent, as the case may be, are enough in the circumstance to make good or, say, compensate the genuine loss of the aggrieved party to an infringement suit. The substantive remedies available to a successful plaintiff at any stage in any suit for patent infringement could, however, be derived from the express as well as by necessary implication of the provisions of the Patents Act, 1970 dealing with the “Reliefs in suit for infringement”. Its Sec. 108 declares in terms quoted below:

Remote sensing provides large-scale information about crops and agricultural environments through satellite, aerial and other sensing technologies. This chapter examines the integration of remote sensing and artificial intelligence for crop monitoring and yield prediction. It introduces the fundamentals of agricultural remote sensing, important sensors and data types, vegetation indices and crop health assessment. Data acquisition and preprocessing are followed by applications of AI models for monitoring crop conditions and predicting yields. Remote sensing datasets can be combined with machine learning and other AI techniques to identify patterns associated with crop performance. The chapter also discusses case studies, limitations, emerging technologies and future research opportunities in intelligent crop monitoring and yield forecasting

Remote sensing and Geographic Information Systems provide spatial information for monitoring crops, land, soil and water resources. This chapter introduces their fundamental principles and explains developments involving satellites, UAVs, hyperspectral sensors, thermal imaging and cloud-based geospatial platforms. Analytical techniques include vegetation indices, time-series analysis, spatial modelling and artificial intelligence. Applications cover crop-health monitoring, yield forecasting, irrigation planning, drought assessment, pest and disease identification and soil-resource management. Integration with IoT, automation and other digital technologies improves the timeliness and resolution of agricultural information. These tools support evidence-based decisions responding to food-security, climate-change and natural-resource sustainability challenges.

4.1 Introduction
Having explored the direct, “hands-on” approach of in situ observations in the previous chapter, we now turn our attention to remote sensing. In contrast to in situ methods, remote sensing allows us to gather information about the atmosphere without physically touching it. Instead, it relies on the detection of electromagnetic radiation (or acoustic waves) that has been emitted, reflected, or scattered by the atmosphere or its constituents.
This chapter will focus specifically on ground-based remote sensing platforms. Positioned on or near the Earth’s surface, these instruments offer unique advantages for continuous monitoring of the atmosphere above a fixed location, providing valuable insights into vertical profiles, temporal evolution, and localized phenomena. From radars that peer into storms to lidars that probe aerosols and winds, and radiometers that measure emitted radiation, ground-based remote sensing provides a vital link between highly localized in situ measurements and the broader spatial coverage offered by satellite and
airborne systems.
We will delve into the fundamental principles behind several key groundbased remote sensing instruments used in meteorology. This will include an examination of how they interact with the atmosphere, the types of atmospheric parameters they can measure (such as precipitation, wind, temperature, humidity, aerosols, and trace gases), and the strengths and limitations of each technique. By understanding the capabilities of these ground-based “eyes” on the sky, we can better appreciate their contribution to weather forecasting, atmospheric research, and environmental monitoring.

Remotely gathered data are available from a range of sources and data collection techniques is often one type of tool that is not always found within the public domain easily. This is larger due to the fact that most of the data are acquired by equipment is expensive to build and maintain. However, there are many types of basic imagery, high-quality imageries are readily available widely at subsidized costs, particularly the purpose intented.

In beginning of aerial photography, the photos were taken to evaluate existing topography, plan observation and sampling incursion. After World War II, the assessments of aerial photographic data were much more difficult, and real geological data started to be extracted. The use of stereoscopic pairs enabled geologist to explain height structural features. But, the basic use of remote sensing data were collected was in explanation. These trends of comparative photography until development took place into the satellite age when satellite imagery began popular and commercially available. The availability of various imageries in several combinations opened a option to analyze regions in much more detail. Apart from this, the multiple flying allowed a prospect to be viewed in various light during differnt seasons. The development drastically decreased the cost of regional exploration by minimizing repeated trips to a place for reassessing. This permitted data to be gathered from the tropics and arid regions that was previously difficult task in wide regional field exploration. As computer age progressed being developed and enhanced the value of data that allows imagery as digitally highlighted specific features. Ground features like differential cropping, drainage patterns, and folds/faults may be identified.

Research and development plays a central role in innovation, product improvement, cost optimization, and competitiveness in the ice cream industry. This chapter explains the distinction between research, development, and new product development and examines the responsibilities of an R&D department. It covers formulation development, pilot and plant trials, ingredient evaluation, shelf-life studies, regulatory considerations, supplier collaboration, product costing, and commercialization. The chapter also highlights the importance of cooperation between R&D, QA, production, procurement, marketing, and finance. Key performance indicators and common mistakes are discussed to strengthen the effectiveness of R&D programmes. The chapter ultimately connects scientific innovation with manufacturing feasibility, consumer expectations, regulatory compliance, and commercial success

5.1. Research methodology

Research methodology is a thorough investigation plan and the manual for conducting the research. This chapter’s examination of methodology aims to help readers comprehend the ideas, strategies, and tactics used to plan a study, gather data, analyse it, and interpret it in order to reveal reality and develop theories. This chapter has been classified under various sub headings for clear understanding:

(i) Locale of research.

 (ii) Pilot study.

 (iii) Methods of sampling.

 (iv) Variables and their empirical measurement.

 (v) Preparation of the interview schedule.

 (vi) Tools and techniques of data collection.

 (vii) Statistical analysis and interpretation of data.

2.1. Concept of review of literature

Research is a continuous process. For any scientific investigation, previous f indings provide basis to the research. It also helps to know the previous research work done in that area and acts as a torch for the new researchers. The review of literature is one of the important aspects in the research process. It helps the researcher to keep his work going in right and appropriate direction. To point out prior research in the area of interest and how our findings connect to past studies, a review of the literature is conducted. The proposed study is new in its subject treatment. However, an attempt is made here to put together some of the closely related research findings in the area.

ABSTRACT

This paper provides an overview on existing IP protection and registration systems of India and adds information culled from publicly available sources pertaining to modernization efforts of Government of India towards establishment of foolproof IP protection in accordance with international treaties, conventions and bilateral and multilateral agreements.

The field is ploughed once and harrowed twice or thrice until the soil becomes well puddle. Beds are made slightly raised of 1 – 1.5 m in width and conveniently large in size and drainage channels in between the beds. The total area of nursery required to plant one hectare of land is 20 cents (800 m2 ). This method is suited where assured irrigation facilities are available. The beds should not be allowed to dry because they develop cracks and the seedlings will get spoiled. This method keeps down the weeds in the nursery. Seedlings are transplanted at 21-25 and 25-30 days age for SDV and MDV, respectively. Sparse sowing is recommended in case of hybrid rice. One kg of hybrid seed is sown in one cent area of nursery. This helps in good tillering and robust seedlings and makes it possible to transplant single seedling per hill. Seedlings are planted at 20-25 days.
