Raspberry pi Part 23
The Raspberry Pi is a series of credit card–sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.
The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier Farnell), RS Components and Egoman. These companies sell the Raspberry Pi online. Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red colouring and lack of FCC/CE marks. The hardware is the same across all manufacturers.
The original Raspberry Pi is based on the Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and was originally shipped with 256 megabytes of RAM, later upgraded (models B and B+) to 512 MB. The system has Secure Digital (SD) (models A and B) or MicroSD (models A+ and B+) sockets for boot media and persistent storage.

Lecture 1
The Socket API
For Chapter 4 of your second textbook
You need to read your book and practice the exercises. This is just an extra note for the chapter.
Read this lecture after you have read chapter 4 of your second textbook.
Note: I included extra file for those students who do not have SSH on their Windows.
Introduction
For the first part of the semester we study distributed programming. The programs are in Java. You can either use windows (XP, Vista, 7), and/or Linux. I assume you have a good knowledge in Java. However if you need tutorial in this language I can post or email my tutorial. But this tutorial is rather sizeable and may take a lot of your time. We use eclipse. I have a small tutorial about installing Java, eclipse, a couple of simple java programs to help you to trace a Java program using the debugging facilities of eclipse.
As always I try to clarify the subject by small programs rather than the big programs in the book to make it easier to follow.
Note: A good website on sockets is: http://docs.oracle.com/javase/tutorial/networking/TOC.html
4.1 Background
Through this part we like to have access to 2-3 computers. Let us assume a client program would like to request implementation of a task via a number server programs. I suggest having one server program in your Windows operating system and one in your account in our school server. Below are a couple of simple examples. I explain the APIs later. Just run those to make sure things are under control.
Example 1: In the following program the client asks a server to add numbers 5 and 7.
The server program:
import java.io.*;
import java.net.*;
publicclass MyServer {
publicstaticvoid main(String[] args) throws IOException {
ServerSocket serverSocket = null;
try {//Keep this number. For the pace server this is the number we must use.
serverSocket = new ServerSocket(16790);
Socket clientSocket = null;
clientSocket = serverSocket.accept();
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
out.println("5 + 7 is: 12");
out.close();
clientSocket.close();
serverSocket.close();
} catch (IOException e) {
System.out.println("Error: " + e);
System.exit(0);
}
}
}
The client program:
import java.io.*;
import java.net.*;
publicclass MyClient {
publicstaticvoid main(String[] args) throws IOException {
Socket clientSocket = null;
BufferedReader in = null;
int ip;
try {//Keep this number. For the pace server this is the number we must use.
ip = 16790;
InetAddress host = InetAddress.getByName("localhost");//("vulcan.seidenberg.pace.edu");
clientSocket = new Socket(host, ip);
in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
String s = in.readLine();
while(s != null){
System.out.println(s);
s = in.readLine();
}
i.
Python networking
This document provides an overview of network programming in Python. It discusses how Python allows both low-level socket access for building clients and servers as well as higher-level access to application protocols like FTP and HTTP. It then describes socket programming concepts like domains, types, protocols and functions for binding, listening, accepting, connecting, sending and receiving data. Simple client and server code examples are provided to demonstrate creating a basic socket connection between two programs. Finally, commonly used Python network modules for protocols like HTTP, FTP, SMTP and more are listed.

1. Objective Getting Started: Familiarize yourself with socket programming. Implement:
Develop a simple chat application for message exchange among remote peers. 2. Getting Started
Socket Programming: Beej Socket Guide: http://beej.us/guide/bgnet 3. Implement 3.1
Programming environment You will write code with any programming language you feel
comfortable. NOTE: You should (1) use TCP Sockets in your peer connection implementation;
(2) handle multiple socket connections; (3) integrate both client-side and server-side code into
one program and run on each peer. 3.2 Running your program Your process (your program when
it is running in memory) will take one command line parameters. The parameter indicates the
port on which your process will listen for the incoming connections. For example, if your
program is called chat, then you can run it like this: ./chat 4322 , where 4322 is the listening port.
Run your program on three computers and perform message exchange. 3.3 Functionality of your
program When launched, your process should work like a UNIX shell. It should accept incoming
connections and at the same time provide a user interface that will offer the following command
options: (Note that specific examples are.

This document discusses network programming in Python using sockets. It explains that sockets allow communication across networks and the Python socket module provides an interface to work with sockets. It then describes how to create server and client sockets, including binding, listening, accepting connections, and sending/receiving data. It also covers different socket address families like AF_INET for IPv4 and provides code examples for a basic echo server and handling multiple clients using threads or processes.
Socket Programming it-slideshares.blogspot.com
Socket programming allows applications on networked computers to communicate reliably using TCP or unreliably using UDP. A socket represents an open connection between two endpoints and has methods to get input/output streams, the remote host/port, and local port. A client socket connects to a server, while a server socket listens on a port and accepts connections from clients.

Socket programming
The document discusses sockets and the client-server model for interprocess communication. It describes what sockets are, the different types of sockets (STREAM, DATAGRAM, RAW), and how they are used for reliable and unreliable communication between processes. It provides code examples for creating, connecting, sending, receiving and closing sockets in both client and server applications using TCP and UDP. Key system calls for sockets like socket(), bind(), listen(), accept(), connect(), send(), recv(), close() are also explained.
Socket.io (part 1)
An unconventional tutorial to basic socket.io features. Socket.io basic features are explained first of all taking a look directly at the browser (hacker approach) and then taking a look at the documentation (and some code examples).

The document outlines the course outcomes of an Advanced Java Programming course (C603). The 5 outcomes are:
1. Design GUI using AWT and Swing.
2. Develop programs using event handling.
3. Use network concepts like client/server and sockets in programs.
4. Develop programs using JDBC to connect to databases and execute queries.
5. Develop web programs using servlets and JSP.
Sockets
Sockets provide an abstraction for network communication between processes. They define endpoints for connections that are identified by IP addresses and port numbers. There are two main types - stream sockets which provide reliable connected service using TCP, and datagram sockets which provide unreliable datagram service using UDP. To use sockets, an application creates a socket, binds it to an address, listens/accepts for incoming connections, and sends/receives data. Key functions include socket(), bind(), listen(), accept(), connect(), send(), and recv(). Select() allows monitoring multiple sockets to avoid blocking. Proper use requires consideration of addressing, port numbers, error handling, and blocking behavior.

16network Programming Servers
The document discusses how to create network servers in Java. It describes the key steps to implement a server as: 1) creating a ServerSocket to listen for connections on a port, 2) using accept to get a Socket for communicating with each client, and 3) reading/writing to the Socket's input/output streams. It provides an example generic network server and explains how to create an HTTP server by reading the client request and sending an HTTP response. The document also covers adding multithreading by processing each client connection in a separate thread to improve performance.

Lecture 1
The Socket API
For Chapter 4 of your second textbook
You need to read your book and practice the exercises. This is just an extra note for the chapter.
Read this lecture after you have read chapter 4 of your second textbook.
Note: I included extra file for those students who do not have SSH on their Windows.
Introduction
For the first part of the semester we study distributed programming. The programs are in Java. You can either use windows (XP, Vista, 7), and/or Linux. I assume you have a good knowledge in Java. However if you need tutorial in this language I can post or email my tutorial. But this tutorial is rather sizeable and may take a lot of your time. We use eclipse. I have a small tutorial about installing Java, eclipse, a couple of simple java programs to help you to trace a Java program using the debugging facilities of eclipse.
As always I try to clarify the subject by small programs rather than the big programs in the book to make it easier to follow.
Note: A good website on sockets is: http://docs.oracle.com/javase/tutorial/networking/TOC.html
4.1 Background
Through this part we like to have access to 2-3 computers. Let us assume a client program would like to request implementation of a task via a number server programs. I suggest having one server program in your Windows operating system and one in your account in our school server. Below are a couple of simple examples. I explain the APIs later. Just run those to make sure things are under control.
Example 1: In the following program the client asks a server to add numbers 5 and 7.
The server program:
import java.io.*;
import java.net.*;
publicclass MyServer {
publicstaticvoid main(String[] args) throws IOException {
ServerSocket serverSocket = null;
try {//Keep this number. For the pace server this is the number we must use.
serverSocket = new ServerSocket(16790);
Socket clientSocket = null;
clientSocket = serverSocket.accept();
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
out.println("5 + 7 is: 12");
out.close();
clientSocket.close();
serverSocket.close();
} catch (IOException e) {
System.out.println("Error: " + e);
System.exit(0);
}
}
}
The client program:
import java.io.*;
import java.net.*;
publicclass MyClient {
publicstaticvoid main(String[] args) throws IOException {
Socket clientSocket = null;
BufferedReader in = null;
int ip;
try {//Keep this number. For the pace server this is the number we must use.
ip = 16790;
InetAddress host = InetAddress.getByName("localhost");//("vulcan.seidenberg.pace.edu");
clientSocket = new Socket(host, ip);
in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
String s = in.readLine();
while(s != null){
System.out.println(s);
s = in.readLine();
}
i.
Python networking
This document provides an overview of network programming in Python. It discusses how Python allows both low-level socket access for building clients and servers as well as higher-level access to application protocols like FTP and HTTP. It then describes socket programming concepts like domains, types, protocols and functions for binding, listening, accepting, connecting, sending and receiving data. Simple client and server code examples are provided to demonstrate creating a basic socket connection between two programs. Finally, commonly used Python network modules for protocols like HTTP, FTP, SMTP and more are listed.

Develop a simple chat application for message exchange among remote peers. 2. Getting Started
Socket Programming: Beej Socket Guide: http://beej.us/guide/bgnet 3. Implement 3.1
Programming environment You will write code with any programming language you feel
comfortable. NOTE: You should (1) use TCP Sockets in your peer connection implementation;
(2) handle multiple socket connections; (3) integrate both client-side and server-side code into
one program and run on each peer. 3.2 Running your program Your process (your program when
it is running in memory) will take one command line parameters. The parameter indicates the
port on which your process will listen for the incoming connections. For example, if your
program is called chat, then you can run it like this: ./chat 4322 , where 4322 is the listening port.
Run your program on three computers and perform message exchange. 3.3 Functionality of your
program When launched, your process should work like a UNIX shell. It should accept incoming
connections and at the same time provide a user interface that will offer the following command
options: (Note that specific examples are.

This document discusses network programming in Python using sockets. It explains that sockets allow communication across networks and the Python socket module provides an interface to work with sockets. It then describes how to create server and client sockets, including binding, listening, accepting connections, and sending/receiving data. It also covers different socket address families like AF_INET for IPv4 and provides code examples for a basic echo server and handling multiple clients using threads or processes.
Socket Programming it-slideshares.blogspot.com
Socket programming allows applications on networked computers to communicate reliably using TCP or unreliably using UDP. A socket represents an open connection between two endpoints and has methods to get input/output streams, the remote host/port, and local port. A client socket connects to a server, while a server socket listens on a port and accepts connections from clients.

Socket programming
The document discusses sockets and the client-server model for interprocess communication. It describes what sockets are, the different types of sockets (STREAM, DATAGRAM, RAW), and how they are used for reliable and unreliable communication between processes. It provides code examples for creating, connecting, sending, receiving and closing sockets in both client and server applications using TCP and UDP. Key system calls for sockets like socket(), bind(), listen(), accept(), connect(), send(), recv(), close() are also explained.

The document outlines the course outcomes of an Advanced Java Programming course (C603). The 5 outcomes are:
1. Design GUI using AWT and Swing.
2. Develop programs using event handling.
3. Use network concepts like client/server and sockets in programs.
4. Develop programs using JDBC to connect to databases and execute queries.
5. Develop web programs using servlets and JSP.
Sockets
Sockets provide an abstraction for network communication between processes. They define endpoints for connections that are identified by IP addresses and port numbers. There are two main types - stream sockets which provide reliable connected service using TCP, and datagram sockets which provide unreliable datagram service using UDP. To use sockets, an application creates a socket, binds it to an address, listens/accepts for incoming connections, and sends/receives data. Key functions include socket(), bind(), listen(), accept(), connect(), send(), and recv(). Select() allows monitoring multiple sockets to avoid blocking. Proper use requires consideration of addressing, port numbers, error handling, and blocking behavior.

When acting as a neurotransmitter NO binds to the iron atom in vario.pdf
When acting as a neurotransmitter NO binds to the iron atom in various heme containing
proteins. Is the N or the O atom more likely to be directly attached to the Fe? Explain.
Solution
Most iron enzymes engage iron either as heme or as a special arrangement of iron with sulphur
groups referred to as iron–sulfur centers (FeS) .Iron in heme bears a striking resemblance to
magnesium ion in chlorophyll. Heme basically is a porphyrin ring system with iron positioned in
the center, is the most common form of iron in biological proteins. In cytochrome c, a common
heme protein in the mitochondria, the axial ligands to the iron are occupied by histidine and
methionine from the protein. Heme enzymes include calalase and peroxidase. As components of
iron–sulphur centers, iron enters into multiple cluster arrangements with cysteine residues on
enzymes that offer a more direct contact with the protein. These centers differ in their complexity
from the simple 2Fe–2S to the more elaborate 4Fe–4S . Iron in these centers binds substrates as
well as transfer electrons and takes part in reactions involving dehydrations and rearrangements.
Enzymes with iron–sulphur centers include xanthine oxidase, succinate dehydrogenase,
aconitase, and nitrogenase
As a neuromodulator or neurotransmitter, NO is released from the synthesis place
diffuses through the plasma membranes due to its concentration gradients. NO can
directly interact with the cysteinyl side chains of peptides and proteins, iron-
containing heme groups, superoxide anion and oxygen. Since the life-span of NO‚
is Only few seconds it is easily inactivated. It has been suggested that some intermediate
compounds, for example S-nitrosothiols may act as a carrier system to stabilize, target
and to preserve its biological activity. S-nitrosothiols are readily formed from
glutathione and NO. Since neurons and glial cells contain GSH at high concentrations,
there is a good chance for the reaction to occur. There is indeed evidence that GSNO
is synthetized in the CNS.
S-nitrosothiols have a wide range of effects: e. g., antimicrobial effect, inhibition of
platelet aggregation, bronchodilation and vasodilation..

What is the difference between a HTML element’s id attribute and nam.pdf
What is the difference between a HTML element’s id attribute and name attribute?
Solution
The form input element id has nothing to do with the data contained within the element. Input
element ids are for hooking the element with JavaScript and CSS. The name attribute is used in
the HTTP request sent by your browser to the server as a variable name associated with the data
contained in the value attribute.
In other words, By using id attribute we can validate and manipulate the value of an element at
client side. By using name attribut, we can validate and manipulate the value of an element at
server side.
In java script, by using id attribute we can get the value of input element.
document.getElementById(\"id\").value;
In server side, by using name attribute we can get the value of input element.
request.getParameter(\"name\");.

TrueFalse A virtual private network is a way to use the Internet to.pdf
True/False A virtual private network is a way to use the Internet to create a connection between
a remote user and a central location. IPsec encrypts the packet data but not the header
information. L2TP uses IPsec for its encryption. Kerberos is an authentication protocol used for
logging into Windows and uses a ticket granting system that sends an encrypted ticket to the
user\'s machine. A digital signature is used to guarantee who sent a message. This is referred to
as authenticity. Public key encryption is fast becoming the most widely used type of encryption
because there are no issues to deal with concerning distribution of keys. PGP involves private
key encryption. The most widely used symmetric key algorithm is Advanced Encryption
Standard. Cipher text is encrypted text. Binary numbers are made up of 0s and 1s.
Solution
Answer:
1) True
explanation:
=> A VPN, or Virtual Private Network, allows you to create a secure connection to another
network over the Internet.
2)true
explanation:
=>IPsec includes Encapsulating Security Payload (ESP) to encrypt the data and provide
confidentiality
3) TRUE
explanation:
=> L2TP does not encrypt the tunnel itself but often uses IPsec for encryption.
5) True
explanation:
=> Digital signatures are the public-key primitives of message authentication.
=> A valid digital signature gives a recipient reason to believe that the message was created by a
known sender.
6) True
explanation:
=> Public key encryption in turn provides a solution to key distribution and data transmission
issues. Used together, performance and key distribution are improved without any sacrifice in
security.
7) False.
8) True
explanation:
=> Encryption algorithms that use the same key for encrypting and for decrypting information
are called symmetric- key algorithms.
=>The symmetric key is also called a secret key because it is kept as a shared secret between the
sender and receiver of information.
9) true
explanation:
=>An encryption function takes cleartext and a key as input and returns ciphertext.
10) TRUE
explanation:
=>A binary code represents text or computer processor instructions using the binary number
system\'s two binary digits, 0 and 1..

So above statement that the total physical units accounted for is the sum of the units completed
and transferred out during the period plus the units in beginning wip inventory is False
So above statement is False.
The probability that a teacher will give an unannounced test duri.pdf
The probability that a teacher will give an unannounced test during any class is 1/5. If a student
is absent twice ,then probability that misses atleast one test is ?
Solution
Given the probability of teacher will give an unannounced test during any class is 1/5.
The probability of not missing test 1-1/5=4/5
probability of missing test in only one day 2(4/25)=8/25
probability of missing test on both the day (1/5)*(1/5)=1/25
probability that misses atleast one test is (8/25)+(1/25)=9/25
probability that misses atleast one test is 9/25.

The IP network is a virtual network and must rely on a link layer ne.pdf
The IP network is a virtual network and must rely on a link layer network to transport a frame.
What elements support getting an IP frame over an Ethernet LAN?
Solution
The data link layer (L2) is the second layer of the seven-layer OSI model of computer
networking. This layer is the protocol layer that transfers data between adjacent network nodes in
a wide area network (WAN) or between nodes on the same local area network (LAN) segment.
The data link layer, also sometimes termed as the link layer, is where many wired and wireless
local area networking (LAN) technologies primarily function.
Ethernet is the most widely used local area network (LAN) in metropolitan area networks
(MAN). Ethernet is a link layer protocol in the TCP/IP stack. It describes how networked devices
can format data for transmission to other network devices on the same network segment, and
how to put that data out on the network connection. It was commercially introduced in 1980 and
first standardized in 1983 as IEEE 802.3, and has since been refined to support higher bit rates
and longer link distances.
The data link layer is divided into two sublayers: logical link control (LLC) and media access
control (MAC).By separating LLC and MAC functions, interoperability of different network
technologies is made easier.
Data Link Layer Functions: Given below are the key tasks performed at the data link layer:
Logical Link Control (LLC): Logical link control refers to the functions required for the
establishment and control of logical links between local devices on a network. It provides
services to the network layer above it and hides the rest of the details of the data link layer to
allow different technologies to work seamlessly with the higher layers. Most local area
networking technologies use the IEEE 802.2 LLC protocol.
Media Access Control (MAC): This refers to the procedures used by devices to control access to
the network medium. Since many networks use a shared medium, it is necessary to have rules for
managing the medium to avoid conflicts. Ethernet uses the CSMA/CD method of media access
control, while Token Ring uses token passing.
Data Framing: The data link layer is responsible for the final encapsulation of higher-level
messages into frames that are sent over the network at the physical layer.
Addressing: The data link layer is the lowest layer in the OSI model that is concerned with
addressing: labeling information with a particular destination location. Each device on a network
has a unique hardware address or MAC address imbined with the hardware i.e present in network
interface card (NIC) to uniquely identify the device.
Error Detection and Handling: The data link layer handles errors that occur at the lower levels of
the network stack. For example, a cyclic redundancy check (CRC) field is often employed to
allow the station receiving data to detect if it was received correctly.
The hardware address is used for the MAC sublayer addressing. Ethernet uses the.

Table 1 Endowment of Labor and Capital US 100 20 Canada 10 Workers Machines 1. Based on
Table 1, according to the Heckscher-Ohlin Theorem, Canada exports should be goods that A)
intensively use labor input. B) intensively use capital input. C) use capital and labor in about
equal proportions D) use either labor or capital input, depending on the good. 2. Suppose that
Brazil is capital abundant and Chile is natural resource abundant. If timber is natural resource
intensive and computers are capital intensive, then according to the Stolper Samuelson Theorem,
the incomes of the owners of trade with Brazil begins A) capital B) labor C) natural resources D)
It is impossible to determine which will be favored. are likely to rise in Chile after
Solution
1) According to Heckscher Ohlin Theorem, A country will export the commodity in which it
uses its intensively endowed factor. Since Canada has more machine per worker compared to
US. Thus Canada is more capital intensive and will export the good that intensively uses capital
input. ans is B.
2) Since Brazil is capital abundant, and computer are capital intensive then Brazil will export
computer and Chile will export Timber. Thus income of natural resources are likely to rise in
Chile
Thus ans is C.

Lesson #1 - Discussion Forum – Linkage between Public Administration and Information
Technology
The article “Computing and Public Organizations” by Kraemer and King is an interesting look
back at the prevailing questions and concerns thirty years ago about the potential impact of the
use of computers in public organizations. The main point of the authors\' discussion is whether a
wide-spread organizational use of computers would affect the centralized or decentralized nature
of an organization. While the authors conclude that any move, either way, would involve more
factors than just the use of computers, they do seem to come down on the side of computer use
increasing the centralization of organizational decision making. When considering the impact of
computer use on the centralization of decision making in public organizations as it stands today,
thirty years after the article was written, it is still difficult to make a definitive statement on
whether organizations have become more or less centralized due to the use of information
technology. In some cases, data gathering both with and without IT is so decentralized
throughout an agency that a desired level of centralization is never achieved. A case in point is
the Veterans Administration, where data from field offices were either inefficiently or never sent
to regional offices that could make service-related decisions, an outcome of decentralization that
had very negative consequences for the veterans that are supposed to be the focus of the agency.
Other government agencies also suffer from having so many points of entry to a centralized
system that the public is uncertain how to access the information they need. An example would
be the military’s health insurance program, which has three or four portals that each accomplish
a different task within the overall program.
A strong and well-organized linkage between public agencies and information technology is
a deciding factor in how beneficial the use of technology is to public organizations.
Solution
I disagree with the fact the IT helps in the centralization of decision making as well as with the
point that it is difficult to determine whether IT helps in decentralization or centralization. I
believe IT has helped in the decentralization of decision making especially in public
administration. The banking sector is a very good example.
Centralization is where the distance- between where the problems arise and where the solution is
decided- is greater. In decentralization, this distance is smaller and decisions are solved closer to
the place where the problems arise.
Decision making depends upon many factors- like access to information, knowledge, experience,
skills, abilities, talent etc. With the inflow of technology into the hands of everyone, data
collection, gathering, assortment and analysis has become easier. Data is converted into
meaningful information and then into.

subject.....project management.
Tools and Processes Based on the progressive case study (PCS) project, you will need to develop
a list of tools and processes that you would use as the contractor of record for opening the new
division office.
•Will you use subcontractors for different parts of the project?
•How will you maintain contact communication? •How will you track progress, milestones, and
setbacks?
•How will you monitor resources and budget?
•What reporting systems will you use?
You are not expected to address all of these areas, though this is not an exhaustive list. Choose
one or two components and describe the tools and processes you will use, then explain the
rationale for using these tools. You may choose to use a certain tool as that is where your
experience is, or it is more cost effective for example.
not less than 150 words
A project team requires individuals from the cross-functional area who can come and work
together on different aspects of the project. In this regard, a project based organizational structure
will be developed that will be flat in nature. The first parameter of the selection of the team
member is the ability to work in the respective areas of the project and or the past experience of
working on similar projects. The second parameter is the ability to manage a dual line of
command (line and project) while working on the project. The third parameter is the propensity
to work in a team and complement each other so that project work runs smoothly. The fourth
parameter is the ability to take decisions with the given authority so that project work is not
delayed due to the decision-making process. Besides, there should be guidelines related to the
scope, objectives, time-based milestones as well as closure of the project. It should be based on
the ethical principles.
Regarding the challenges, the first challenge is the procurement of resources to build capacity as
no any department or function wants to release the best employees. The second challenge is the
building of the clarity in command so that any ambiguity is eliminated. The third challenge is the
timely availability of resources and funds other than HR to start the project. The next challenge
is to build the cooperation based team culture in the project team
Solution
TRACKING PROGRESS, MILESTONES, AND SETBACKS:
A contractor needs to keep a close check on the progress of the project on which he is working.
Project management is a difficult and very important task and requires skills and expertise of the
contractor so as to make sure that the project is working as planned for.
Keeping a track on the progress of the project is must from time to time and making sure that the
milestones are achieved properly and if in case of any setbacks, recording why it happened.
Following are the list of the tools that can be used to track the progress, milestones and setback
of the project:

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
