Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
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.
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
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

microcomputer.
It contains an Arithmetic and Logic Unit(ALU), a Program
Counter(PC),a Stack Pointer(SP), a few working registers,
a clock timing circuit and interrupt circuits.
It doesn’t contain RAM, ROM,I/O ports, Timers etc on the
chip and hence called General Purpose CPU’s.
3. CONTD..
A system designer using a general purpose microprocessor
must add the RAM, ROM, I/O ports, and timers externally
to make them functional.
Although the external RAM, ROM, I/O ports makes these
systems bulkier and much more expensive, they have the
advantage of versatility such that the designer can decide
on the amount of RAM, ROM, and I/O ports needed to fit
the task at hand.
5. MICROCONTROLLER
A microcontroller has a CPU (microprocessor) in
addition to a fixed amount of ROM,RAM,I/O ports
and timer all are embedded together on single chip.
Therefore the designer cannot add any external

The fixed amount of on-chip RAM, ROM, and the
number of I/O ports makes them ideal for many
applications in which the cost and space are critical.
10. CONTD..
Central Processor Unit (CPU)

● Internal Ram (data memory)
○ 128 bytes of internal RAM is organised into 3 distinct areas:
■ 32 bytes ranging from addresses 00H to 1FH that make up
32 working registers(each of 8 bits) organised as 4 banks
(bank0, bank1, bank2 & bank3) of 8 registers namely R0, R1,
R2…. R7
● Bits RS0, RS1 of PSW register determine which
registers are currently in use.
● By default, register bank 0 is used.
●
29. ● Internal Ram (data memory)
○ 128 bytes of internal RAM is organised into 3
distinct areas:
■ A bit addressable area of 16 bytes occupies RAM
addresses ranging from 20 to 2Fh, forming a total of 128
addressable bits.
● Individual bits of a memory location can be manipulated
■ 80 bytes of general purpose area ranging from 30h to 7FH
used for read/write storage and is normally called as
SCRATCHPAD

31. SFRs
○ 8051 has a group of specific internal registers
(21nos) each called Special Function Registers
(SFR) and occupy another 128 bytes of memory
(80 to FF) .
○ All operations that do not use 128 bytes (00h to 7Fh) of
internal RAM are done by SFRs.
○ SFR include A-register, B-register, DPH, DPL, IE, IP, P0,P1,P2,P3,
PCON, PSW, SCON, SBUF, SP, TMOD, TCON, TL0, TL1, TH0,

33. ● Stack & Stack
Pointer
○ Stack is an area of internal RAM that is used in conjunction with
certain
opcodes to store and retrieve data quickly.
○ 8 bit Stack Pointer (SP) is used by 8051 to hold an internal
RAM address which is called the top of the Stack and is the
address where last byte of data is stored.
○ When data is to be placed on the stack SP is incremented
just before the data is stored on stack, so that the stack grows
upwards.
○ As the data is retrieved from the stack, SP
decrements after the retrieval of data.

● Internal ROM (program memory)
○ 8051 has 4KB of on-chip ROM
(22x210bytes)
○ This is used for storing system program and has addresses ranging from
000h to FFFh (0 to 4095).
○ Program addresses higher than 0FFFh, that is those exceeding internal ROM capacity
will cause 8051 to automatically fetch code bytes from external program memory.
○ Fetching from external memory is enabled by keeping EA pin External Access pin) of
8051 to ground.
35. I/O PORTS :
There are totally four 8-bit I/O Ports namely PORT 0 , PORT 1 ,
PORT 2 , PORT 3.
Three out of four ports namely PORT 0 , 2 and 3 are
multifunctional PORTS
37. PROGRAM MEMORY (ROM) OF 8051
MICROCONTROLLER
In 8051 Microcontroller, the code or instructions to be executed
are stored in the Program Memory, which is also called as the
ROM of the Microcontroller.
The original 8051 Microcontroller by Intel has 4KB of internal
ROM.
In case of 4KB of Internal ROM, the address space is 0000H to
0FFFH. If the address space i.e. the program addresses exceed this
value, then the CPU will automatically fetch the code from the
external Program Memory.
39. CONTD..
when the EA Pin is high, the CPU first fetches instructions from
the Internal Program Memory in the address range of 0000H to
0FFFFH and if the memory addresses exceed the limit, then the
instructions are fetched from the external ROM in the address
range of 1000H to FFFFH.
40. CONTD..
There is another way to fetch the instructions: ignore the Internal
ROM and fetch all the instructions only from the External
Program Memory (External ROM).
For this, the EA Pin must be connected to GND. In this case, the
memory addresses of the external ROM will be from 0000H to
FFFFH.
43. CONTD..
The Data Memory or RAM of the 8051 Microcontroller stores
temporary data and intermediate results that are generated and
used during the normal operation of the microcontroller.
Original Intel’s 8051 Microcontroller had 128B of internal RAM.
But almost all modern variants of 8051 Microcontroller have 256B
of RAM.
44. CONTD..
In this 256B, the first 128B i.e. memory addresses from 00H to 7FH is divided
in to Working Registers (organized as Register Banks), Bit – Addressable Area
and General Purpose RAM (also known as Scratchpad area).
In the first 128B of RAM (from 00H to 7FH), the first 32B i.e. memory from
addresses 00H to 1FH consists of 32 Working Registers that are organized as
four banks with 8 Registers in each Bank.
45. CONTD..
The 4 banks are named as Bank0, Bank1, Bank2 and Bank3.
Each Bank consists of 8 registers named as R0 – R7.
Each Register can be addressed in two ways: either by name or by address.
To address the register by name, first the corresponding Bank must be selected.
In order to select the bank, we have to use the RS0 and RS1 bits of the Program
Status Word (PSW) Register (RS0 and RS1 are 3rd and 4th bits in the PSW
Register).
46. CONTD..
The next 16B of the RAM i.e. from 20H to 2FH are Bit – Addressable memory
locations.
There are totally 128 bits that can be addressed individually using 00H to 7FH
or the entire byte can be addressed as 20H to 2FH.
The final 80B of the internal RAM i.e. addresses from 30H to 7FH, is the
general purpose RAM area which are byte addressable.
These lower 128B of RAM can be addressed directly or indirectly.
47. CONTD..
The upper 128B of the RAM i.e. memory addresses from 80H to FFH is
allocated for Special Function Registers (SFRs). SFRs control specific functions
of the 8051 Microcontroller. Some of the SFRs are I/O Port Registers (P0, P1,
P2 and P3), PSW (Program Status Word), A (Accumulator), IE (Interrupt
Enable), PCON (Power Control), etc.
SRFs Memory addresses are only direct addressable.
49. ● Pins 1 – 8 (PORT 1): Pins 1 to 8 are the
PORT 1 Pins of 8051. PORT 1 Pins consists
of 8 – bit bidirectional Input / Output Port with
internal pull – up resistors
● Pin 9 (RST): Pin 9 is the Reset Input Pin. It is
an active HIGH Pin i.e. if the RST Pin is HIGH
for a minimum of two machine cycles, the
microcontroller will be reset. It will reset PC
register to 0000h.
● Pins 10 – 17 (PORT 3): Pins 10 to 17 form
the PORT 3 pins of the 8051 Microcontroller.
PORT 3 also acts as a bidirectional Input /
Output PORT with internal pull-ups.
Additionally, all the PORT 3 Pins have
special functions
49
50. ● Pins 18 & 19: Pins 18 and 19 i.e. XTAL 2
and XTAL 1 are the pins for connecting
external oscillator. Generally, a Quartz
Crystal Oscillator is connected here
● Pin 20 (GND): Pin 20 is the Ground Pin of
the 8051 Microcontroller. It represents 0V
and is connected to the negative terminal
(0V) of the Power Supply.
● Pins 21 – 28 (PORT 2): These are the
PORT 2 Pins of the 8051 Microcontroller.
PORT 2 is also a Bidirectional Port i.e. all
the PORT 2 pins act as Input or Output.
Additionally, when external memory is
interfaced, PORT 2 pins act as the higher
order address byte
50
51. ● Pin 29 (PSEN): Pin 29 is the Program Store
Enable Pin (PSEN). Using this pins,
external Program Memory can be read.
● Pin 30 (ALE/PROG): Pin 30 is the Address
Latch Enable Pin. It is an active high pin.
ALE indicates if port0 provides address or
data. ALE=0 indicates port0 provides data
and if 1 port0 provides address.
● Pin 31 (EA/VPP): Pin 31 is the External
Access Enable Pin i.e. allows external
Program Memory. Code from external
program memory can be fetched only if this
pin is LOW. For normal operations, this pins
is pulled HIGH.
51
52. ● Pins 32 – 39 (PORT 0): Pins 32 to 39 are
PORT 0 Pins. They are also bidirectional
Input / Output Pins but without any internal
pull-ups. Hence, we need external pull-ups
in order to use PORT 0 pins as I/O PORT. In
addition to acting as I/O PORT, PORT 0 also
acts as lower order address/data bus when
external memory is accessed.
● Pin 40 (VCC): Pin 40 is the power supply
pin to which the supply voltage is given
(+5V).
