A futuristic approach for towerless mobile networks wheezy piIJLT EMAS
It is an attempt to develop the mobile networks to
have a wireless voice call happening without the help of the
towers. Our main aim is to remove the towers in the
communication process. The towers have been hazardous to
Living Organism. This project mainly consists of Raspberry pi
and Wi-Fi router. We used two raspberry pi kits of version 3
with Wi-Fi inbuilt on it which can access till the distance of 30
meters,which is used to develop a voice call application to
transfer the voice through the Wi-Fi communication. It would be
possible to expand this communication by the use of WIMAX
which would be able to communicate in the range of kilometers.
For live transmission of audio and video, we have used VOIP
(voice over internet protocol) with the help of gstreamer and gstlaunch
libraries, IEEE standard 802.11 for wireless network,
LCD screen for GUI interface ,programmed in Python language
as it is recommended by Raspberry pi foundation and is freely
available for LINUX, Windows operating system. A hardware
implementation is developed and the results were analyzed for
performance.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Raspberry Pi was built to be used, but not abused.
Every P.C.B. should be handled with care.
Handle the Pi only by the edges of the board itself. Avoid
touching or holding any of the components on the board.
Rough Handling can cause solder points to fail and may
result in short circuits, but be careful with the GPIO pins as
well.
While connecting Hardware, double check the connections
and then power it up. Raspberry Pi GPIO’s are not 5V
tolerant.
27. Preparing a SD Card
Format a SD card that is 4GB or larger as FAT.
Use the Tool – SDFormatter (How ?)
Download and extract the files from the NOOBS zip file.
Copy the extracted files onto the SD card that you just
formatted so that this file is at the root directory of the SD
card.
When this process has finished, safely remove the SD
card and insert it into your Raspberry Pi and Power it up.
Raspberry Pi will boot, and a window will appear with a list
of different operating systems that you can install. We
recommend that you use Raspbian – tick the box next to
Raspbian and click on Install.
Wait for it to finish. (15 – 20 mins)

36. Linux Shell
To interact with the Operating System or Hardware we
need to enter some commands in the “Shell”.
Simply put, the shell is a program that takes your
commands from the keyboard and gives them to the
operating system to perform.
In the old days, it was the only user interface available
on a Unix computer.
Nowadays, we have graphical user interfaces
(GUIs) in addition to command line interfaces
(CLIs) such as the shell.
In GUI, we have "terminal emulators” or “consoles”
which are programs that put a window up and let us
interact with the shell.
37. Important Commands
1) ls
“ls” command displays the list of files present in a
given directory.
2) cd
“cd” or change directory command allows the user to
traverse through the directories and file paths.
3) cp
“cp” command is used to copy file(s) from a source to
a destination.
4) mv
Move files from source to destination.
38. Important Commands
5) rm
“rm” command is used to remove file/files.
6) mkdir
“mkdir” command is used to make a new directory or
folder in the current path.
7) rmdir
“rmdir” command is used to remove a directory or
folder in the current path.
8) clear
“clear” command is used to clear the contents on the
terminal window.
39. Important Commands
9) cat
“cat” command is used to concatenate and output the
contents of the given files.
10) pwd
“pwd” command is used to check the present working
directory.
11) sudo
“sudo” allows users to run programs with the security
privileges of super user or root or administrator.
12) chmod
“chmod” allows users to change access modes on
files.
40. Remote Login (ssh)
Secure Shell (ssh) is a network protocol which allows
remote control of Raspberry Pi from another computer
over the network.
Provides access to the Command Line and not to the
Full Desktop Environment.
You can enable or disable the SSH server on your
Raspberry Pi (it is enabled by default).
To Enable SSH, in the Terminal, enter sudo raspi-
config, enable the ssh, finish and exit the menu.
Use a third-party SSH client software on your
Windows System (like puTTy or TeraTerm) and access
Raspberry Pi by entering it’s I.P. Address, user (pi) and
password (raspberry).
To check Raspberry Pi’s I.P. Address, enter ifconfig in
the terminal.
