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.

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.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to

depending on the design and installation requirements.
By integrating these components and technologies, the SMART-KEY device provides users with a versatile and secure means of
controlling their motorcycles through multiple interfaces, offering enhanced convenience and control options.
4. WORKING
This SMART-KEY device working principle is quit similar to the remote control of car keys . To operate this
marquee smart key we are using firebase database add mit app inventor application to make customise api for
Smart Key . In this my key ESP8226 add two channel relay model is used to operate scooty . For this smart key
we have separate application that application name is called Smartkey in that application two buttons are available
one button for turn on Scooty add one more button for finding a scooty . First button Toggle button on and off
when we press on the data will go to firebase database from there it will come to nodemcu . In Nodemcu having
GPI0 pins D0 and D1. D0 pin is to turn on Scooty . D1 pin is to find scooty it means that if we lost Scotty it will
indicate . When data come from firebase database it goes to nodemcu . In nodemcu D0 pin will become high .
Later the data go back for firebase database cloud . This is the working principle of Smart Key . By the same way
using Whatsapp Smartkey is operated . Like when we send message key on in Whatsapp it goes to ThingESP .
From there it goes to nodeMCU D0 will be high . Again from nodemcu to ThingESP Cloud from cloud to
Whatsapp reply like “key turn on” . when D0 will be high the relay will pass the current in the circuit so it can be
used like a switch then scooty will turn on by this way. When it become active low the scooty will turn off and the
relay stop flowing current .
5. EVALAUTION AND RESULT :
CUSTOMIZED APPLICATION FOR SMART-KEY SCOOTY WHEN IT IS IN “ON” and “OFF” state .
10. ESP8266 12-E NodeMCU Kit
The ESP8266 12-E NodeMCU kit pinout diagram is shown below.
11. Best Pins to Use – ESP8266
One important thing to notice about ESP8266 is that the GPIO number doesn’t match the label on the board silkscreen. For example, D0 corresponds to GPIO16 and D1
corresponds to GPIO5.
The following table shows the correspondence between the labels on the silkscreen and the GPIO number as well as what pins are the best to use in your projects, and which
ones you need to be cautious.
The pins highlighted in green are OK to use. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have unexpected behavior mainly at
boot. The pins highlighted in red are not recommended to use as inputs or outputs.
Continue reading for a more detailled and in-depth analysis of the ESP8266 GPIOs and its functions.
Label GPIO Input Output Notes
D0 GPIO16 no interrupt no PWM or I2C support
HIGH at boot
used to wake up from deep
sleep
D1 GPIO5 OK OK often used as SCL (I2C)
D2 GPIO4 OK OK often used as SDA (I2C)
D3 GPIO0 pulled up OK
connected to FLASH button,
boot fails if pulled LOW
D4 GPIO2 pulled up OK
HIGH at boot
connected to on-board LED,
boot fails if pulled LOW
D5 GPIO14 OK OK SPI (SCLK)
D6 GPIO12 OK OK SPI (MISO)
D7 GPIO13 OK OK SPI (MOSI)
D8 GPIO15 pulled to GND OK
SPI (CS)
Boot fails if pulled HIGH
RX GPIO3 OK RX pin HIGH at boot
TX GPIO1 TX pin OK
HIGH at boot
debug output at boot, boot
fails if pulled LOW
A0 ADC0 Analog Input X
12. GPIOs connected to the Flash Chip
GPIO6 to GPIO11 are usually connected to the flash chip in ESP8266 boards. So,
these pins are not recommended to use.
Pins used during Boot
The ESP8266 can be prevented from booting if some pins are pulled LOW or HIGH.
The following list shows the state of the following pins on BOOT:
GPIO16: pin is high at BOOT
GPIO0: boot failure if pulled LOW
GPIO2: pin is high on BOOT, boot failure if pulled LOW
GPIO15: boot failure if pulled HIGH
GPIO3: pin is high at BOOT
GPIO1: pin is high at BOOT, boot failure if pulled LOW
GPIO10: pin is high at BOOT
GPIO9: pin is high at BOOT
13. Pins HIGH at Boot
There are certain pins that output a 3.3V signal when the
ESP8266 boots. This may be problematic if you have relays
or other peripherals connected to those GPIOs. The
following GPIOs output a HIGH signal on boot:
GPIO16
GPIO3
GPIO1
GPIO10
GPIO9
Additionally, the other GPIOs, except GPIO5 and GPIO4, can
output a low-voltage signal at boot, which can be
problematic if these are connected to transistors or relays.
You can read this article that investigates the state and
behavior of each GPIO on boot.
14. Interface Two Channel Relay Module with
ESP8266
Two-Channel Relay Module Pinout
Let’s take a look at the pinout.
15. Control Pins:
VCC pin provides power to the built-in optocouplers and, optionally, the relay’s electromagnet (if you keep the jumper
in place). Connect it to the 5V pin on the ESP8266.
GND is the common ground pin.
IN1 & IN2 pins control the relay. These are active low pins, which means that pulling them LOW activates the relay
and pulling them HIGH deactivates it.
Power Supply Selection Pins:
JD-VCC provides power to the relay’s electromagnet. When the jumper is in place, JD-VCC is shorted to VCC,
allowing the electromagnets to be powered by the ESP8266 Vin line. Without the jumper cap, you’d have to connect it
to a separate 5V power source.
VCC pin is shorted to the JD-VCC pin with the jumper cap on. Keep this pin disconnected if you remove the jumper.
GND is the common ground pin.
Output Terminals:
COM terminal connects to the device you intend to control.
NC terminal is normally connected to the COM terminal, unless you activate the relay, which breaks the connection.
NO terminal is normally open, unless you activate the relay that connects it to the COM terminal.
