• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.

project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Properties of Fluids, Fluid Statics, Pressure MeasurementIndrajeet sahu
Properties of Fluids: Density, viscosity, surface tension, compressibility, and specific gravity define fluid behavior.
Fluid Statics: Studies pressure, hydrostatic pressure, buoyancy, and fluid forces on surfaces.
Pressure at a Point: In a static fluid, the pressure at any point is the same in all directions. This is known as Pascal's principle. The pressure increases with depth due to the weight of the fluid above.
Hydrostatic Pressure: The pressure exerted by a fluid at rest due to the force of gravity. It can be calculated using the formula P=ρghP=ρgh, where PP is the pressure, ρρ is the fluid density, gg is the acceleration due to gravity, and hh is the height of the fluid column above the point in question.
Buoyancy: The upward force exerted by a fluid on a submerged or partially submerged object. This force is equal to the weight of the fluid displaced by the object, as described by Archimedes' principle. Buoyancy explains why objects float or sink in fluids.
Fluid Pressure on Surfaces: The analysis of pressure forces on surfaces submerged in fluids. This includes calculating the total force and the center of pressure, which is the point where the resultant pressure force acts.
Pressure Measurement: Manometers, barometers, pressure gauges, and differential pressure transducers measure fluid pressure.
2. USING SERIAL COMMUNICATION, YOU’LL USE YOUR
ARDUINO TO CONTROL A PROGRAM ON YOUR COMPUTER
You’ve done a lot of cool stuff with the physical world, now it’s time to control
your computer with your Arduino. When you program your Arduino, you’re
opening a connection between the computer and the microcontroller. You can
use this connection to send data back and forth to other applications.
The Arduino has a chip that converts the computer’s USB-based communication
to the serial communication the Arduino uses.Serial communication means that
the two computers, your Arduino and PC, are exchanging bits of information
serially,or one after another in time.
When communicating serially, computers need to agree on the speed at which
they talk to one another. You’ve probably noticed when using the serial monitor
there’s a number at the bottom right corner of the window. That number, 9600
bits per second, or baud, is the same as the value you’ve declared using Serial.
begin(). That’s the speed at which the Arduino and computer exchange data.
A bit is the smallest amount of information a computer can understand.
You’ve used the serial monitor to look at values from the analog inputs; you’ll
use a similar method to get values into a program you’re going to write in a
programming environment called Processing. Processing is based on Java, and
Arduino’s programming environment is based on Processing’s. They look pretty
similar,so you should feel right at home there.
Before getting started with the project, download the latest version of Processing
from processing.org. It may be helpful to look at the “Getting started” and
“Overview” tutorials at processing.org/learning. These will help you to familiarize
yourself with Processing before you start writing software to communicate with
your Arduino.

3. The most efficient way to send data between the Arduino and Processing is by
using the Serial.write() function in Arduino. It’s similar to the Serial.
print() function you’ve been using in that it sends information to an attached
computer, but instead of sending human readable information like numbers and
letters, it sends values between 0-255 as raw bytes. This limits the values that the
Arduino can send, but allows for quick transmission of information.
On both your computer and Arduino, there’s something called the serial buffer
which holds onto information until it is read by a program. You’ll be sending bytes
from the Arduino to Processing’s serial buffer. Processing will then read the bytes
out of the buffer.As the program reads information from the buffer,it clears space
for more.
When using serial communication between devices and programs, it’s important
that both sides not only know how fast they will be communicating, but also
what they should be expecting. When you meet someone, you probably expect a
“Hello!”;if instead they say something like “Thecat is fuzzy”,chances are you will be
caught off guard. With software, you will need to get both sides to agree on what
is sent and received.

5. First, program your Arduino. In setup(), you’ll start serial
communication, just as you did earlier when looking at the values
from an attached sensor. The Processing program you write will
have the same serial baud rate as your Arduino.
In the loop(), you’re going to use the Serial.write()
command to send information over the serial connection.
Serial.write() can only send a value between 0 and 255. To
make sure you’re sending values that fit within that range, divide
the analog reading by 4.
After sending the byte, wait for one millisecond to let the ADC
settle down. Upload the program to the Arduino then set it aside
while you write your Processing sketch.

CODE
THE PROCESSING
CODE
The Processing language is similar to Arduino, but there are
enough differences that you should look at some of their
tutorials and the “Getting Started” guide mentioned before to
familiarize yourself with the language.
Open a new Processing sketch. Processing, unlike the Arduino,
doesn’t know about serial ports without including an external
library.Import the serial library.
You need to create an instance of the serial object,just likeyou’ve
done in Arduino with the Servo library. You’ll use this uniquely
named object whenever you want to use the serial connection.
To use images in Processing, you need to create an object that
will hold the image and give it a name.

7. Createavariablethat willhold the background hue of the Arduino
logo. The logo is a .png file,and it has built-in transparency, so it’s
possible to see the background color change.
Processing has a setup() function, just like Arduino. Here’s
where you’ll open the serial connection and give the program a
couple of parameters that will be used while it runs.
You can change the way Processing works with color information.
Typically, it works with colors in a Red Green Blue (RGB) fashion.
This is similar to the color mixing you did in Project 4, when you
used values between 0 and 255 to change the color of an RGB
LED. In this program, you’re going to use a color mode called
HSB, which stands for Hue, Saturation, and Brightness. You’ll
change the hue when you turn the potentiometer.
colorMode() takes two arguments: the type of mode, and the
maximum value it can expect.
To load the Arduino image into the sketch, read it into the logo
object you created earlier.When you supply the URL of an image,
Processing will download it when you run the program.
With the size() function, you tell Processing how large the
display window will be. If you use logo.width and logo.
height as the arguments, the sketch will automatically scale to
the size of the image you’re using.
Processing has the ability to print out status messages using the
println() command. If you use this in conjunction with the
Serial.list() function, you’ll get a list of all the serial ports
your computerhas when the program firststarts.You’lluse thisonce
you’refinished programmingto seewhat port your Arduino ison.
You need to tell Processing information about the serial
connection. To populate your named serial object myPort with
the necessary information, the program needs to know it is a
new instance of the serial object. The parameters it expects are
which application it will be speaking to, which serial port it will
communicate over,and at what speed.

9. The attribute this tells Processing you’re going to use the serial
connection in this specific application. The Serial.list()
[0] argument specifies which serial port you’re using. Serial.
list() contains an array of all the attached serial devices. The
argument 9600 should look familiar, it defines the speed at
which the program will communicate.
The draw() function is analogous to Arduino’s loop() in that
it happens over and over again forever. This is where things are
drawn to the program’swindow.
Check if there is information from the Arduino. The myPort.
available() command will tell you if there is something in
the serial buffer. If there are bytes there, read the value into the
bgcolor variable and print it to the debug window.
The function background() sets the color of the window. It
takes three arguments. The first argument is the hue, the next
is brightness, and the last is saturation. Use the variable bgcolor
as the hue value, and set the brightness and saturation to the
maximum value, 255.
You’ll draw the logo with the command image(). You need
to tell image() what to draw, and what coordinates to start
drawing it in the window. 0,0 is the top left, so start there.
USE IT Connect your Arduino and open the serial monitor. Turn the
pot on your breadboard. You should see a number of charac-
ters as you twist the knob. The serial monitor expects ASCII
characters, not raw bytes. ASCII is information encoded to
represent text in computers. What you see in the window is
the serial monitor trying to interpret the bytes as ASCII.
When you use Serial.println(), you send information
formatted for the serial monitor. When you use Serial.
write(), like in this application you are running now, you’re
sending raw information. Programs like Processing can
understand these raw bytes.

11. Close the serial monitor. Run the Processing sketch by press-
ing the arrow button in the Processing IDE. Look at the Pro-
cessing output window. You should see a list similar to the
figure below.
This is a list of all the serial ports on your computer. If you’re
using OSX, look for a string that says something like “/dev/
tty.usbmodem411”, it will most likely be the first element in
the list. On Linux, it may appear as “/dev/ttyUSB0”, or simi-
lar. For Windows, it will appear as a COM port, the same one
you would use when programming the board. The number in
front of it is the Serial.list()[] array index. Change the
number in your Processing sketch to match the correct port
on your computer.
Restart the Processing sketch. When the program starts run-
ning, turn the potentiometer attached to the Arduino. You
should see the color behind the Arduino logo change as you
turn the potentiometer. You should also see values printing
out in the Processing window. Those numbers correspond to
the raw bytes you are sending from the Arduino.
154 Project 14
Tweak the Arduino Logo
12. Once you have twisted and turned to your heart’s desire, try replacing the pot
with an analog sensor. Find something you find interesting to control the color.
What does the interaction feel like? It’s probably different than using a mouse or
keyboard, does it feel natural to you?
When using serial communication, only one application can talk to the Arduino at a
time. So if you’re running a Processing sketch that is connected to your Arduino, you
won’t be able to upload a new Arduino sketch or use the serial monitor until you’ve
closed the active application.
With Processing and other programming environments, you can control media on
your computer in some remarkable and novel ways. If you’re excited about the pos-
sibilities of controlling content on your computer, take some time to experiment
with Processing. There are several serial communication examples in both the Pro-
cessing and Arduino IDEs that will help you explore further.
Serial communication enables the Arduino to talk with
programs on a computer. Processing is an open source
programming environment that the Arduino IDE is based
upon. It’s possible to control a Processing sketch with the
Arduino via serial
communication.
