Tracking police man using rf proximity cardAlbert Jose
Security is the important cause in the modern world. Now a day so many schemes have
announced by the banks which very attractive and the people are saving money in banks. At this
point protecting the banks is the main duty of police. Hence police are appointed securities to the
banks and make them to patrol during nights. . They have to go to every banks and streets and
sign the books kept in their places .But some police people forgot their duty and will sleep in a
vacant place and in the morning they get up and in a hurry go to these banks and put a fake time
and date and the signature .To avoid this and to provide more security our proposed system is
giving solution for tracking police man using RF proximity card. A RF proximity card reader with a
microcontroller will be designed and will be placed in every bank. During the patrol time, when a
police man swipe the card it will read the card number and will store it with date and time. The
data can be retrieved by connecting the machine to PC and giving appropriate commands.
Tracking police man using RF proximity card embedded system project explains about
new method for bank officials for checking their security of the bank by implementing accurate
method to control police officials. In present scenario banks are playing important role in providing
security for people for saving their money, gold..Etc. So banks are taking serious steps to
maintain security like hiring police officials at night time for patrolling banks, but there are chances
in irregularity of police officials so this method will provide card system for every police official
who should scratch his card. Data and time is stored inside system which can connect to
computer and analyze details of his attendance

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

• In ARM7 family, LPC2148 is widely used IC.ARM
processor is based on reduced instruction set
computing (RISC) architecture.
• The instruction set of ARM is uniform and fixed
in length. 32-bit ARM processor has two
instruction set: general 32 bit ARM instruction
set and 16-bit Thumb instruction set.
• It supports multiple stage pipelining in a simple
three stage pipeline, the instructions follow
three stages: Fetch, Decode and Execute.
7. TEMPERATURE SENSOR:(LM75):
• The LM75 temperature sensor includes a delta-
sigma analog-digital converter, and a digital over
temperature detector. The host can query the
LM75 through its I2C interface to read
temperature at any time. The OS output
operates in either of two modes, comparator or
interrupt.
8. BELT SENSOR:
• Belt sensor indicates whether seat belts are
fastened. In our prototype we have used Audio
Jack as a Belt sensor. One push button is used to
detect place of the seat belt during the drive.
The push button is placed on the seat belt and
gives logic ’zero’ when the belt is used and logic
‘one’ when the belt is not placed by the driver.
9. DOOR SENSOR (leaf switch)
• In our prototype we use leaf switch as a door
sensor to ensure that whether the door is closed
or open. As this leaf switch is connected, it gives
the logic ‘one’ that means door is closed and if it
gives the logic ‘zero’ it means leaf switch is
separated from each other and door is open.
10. RTC (REAL TIME CLOCK)
• Real time clock (RTC) as the name recommends
our clock module. The DS1307 real time clock IC
is an eight pin device using an I2C interface. The

the microcontroller using MAX232.
13. DATA RETRIEVING FROM EEPROM:
• EEPROM is a computer memory chip that
maintains stored information without requiring a
power source.
• As the accident occur, every detail of the sensor
is calculated and stored in memory. These values
are very useful to know how the accident
occurred.
• This stored data of the accident is useful for
police to investigate the case and to the
Insurance company. As we get the values or data
from black box which is connected to personal
computer by using RS232 cable.
14. • These I2C-compatible electrically erasable
programmable memory (EEPROM) devices are
organized as 8192 x 8 bits (M24C64) and 4096 x 8
bits (M24C32).
• I2C uses a two-wire serial interface, comprising a bi-
directional data line and a clock line.
• The devices carry a built-in 4-bit Device Type
Identifier code (1010) in accordance with the I2C bus
definition.
15. INFRARED SENSOR
• The infrared sensor is to measure the minimum
distance from the vehicle. IR sensor generate
high frequency sound wave and evaluate the
heat being emitted by an object and detecting
motion which is received back by the sensor. Its
distance sensing range is 2cm to 3cm.
16. GAS SENSOR (Smoke Detector)
• A gas detector is a device that detects the
presence of gases in an area, often as part of a
safety system. This type of equipment is used to
detect a gas leak and interface with a control
system so a process can be automatically shut
down.
17. EDR
• An Events Data Recorder (EDR) is a device which
is used to record the movement parameter of a
vehicle mainly used for accident analyzes
purposes and for safety measures. There are
many EDR has designed for automobiles,
however they have to be physically connected to
sensors integrated with the car's engine and
system.
• First, the EDR needs to know when to start
recording and save crash data. EDRs are
triggered by the sensors that detect crash-like
events.
18. • Just like a computer, the EDR has some basic
elements needed for storing data: memory hardware
to hold the data, file system software to save the
data in a standardized format, and an operating
system (OS).
• The primary memory hardware inside EDRs is
typically a flash memory chip, such as eMMC
(embedded multi-media controller) or UFS (universal
flash storage), or sometimes an SD card. The
operating systems used in EDRs are typically real
time operating systems(RTOS) or Linux.
