This document describes an automatic braking system for vehicles that uses ultrasonic sensors to detect obstacles and apply the brakes autonomously. The system consists of an ultrasonic sensor with transmitter and receiver, a microprocessor, DC gear motor, servomotor, and braking components. It works by transmitting ultrasonic waves from the sensor transmitter and detecting reflections from obstacles with the receiver. The microprocessor analyzes the sensor data and controls the servomotor, which applies the brakes through the braking system if an obstacle is detected within a certain distance from the vehicle. This automatic braking system is intended to prevent accidents by braking the vehicle automatically if the driver is unable to brake manually in time upon detecting an obstacle.
This document summarizes a technical seminar on Automatic Emergency Braking (AEB) systems for vehicles. It begins with background on road accidents globally and in India. It then covers the need for AEB to help avoid collisions. The presentation explains how AEB works using sensors like radar and cameras to detect obstacles and apply the brakes autonomously if a collision is detected. It discusses different AEB types and their applications in vehicles. Advantages are around reducing crashes, though disadvantages include cost and limiting driver control. The conclusion is that AEB can help avoid accidents and reduce road deaths and injuries.
An autonomous emergency braking system can help reduce accidents by intervening to brake independently of the driver when critical situations are detected. The system uses ultrasonic sensors and a camera to measure the speed of vehicles ahead and activate the brakes if a collision is likely to occur due to the driver braking too late or unexpectedly. While this can help avoid accidents and reduce injury, some disadvantages are the increased cost and loss of total vehicle control. The system works by sensors detecting obstacles, a microprocessor calculating braking needs, and activating the brakes if needed to avoid a collision.
Advanced driver assistance systems are designed to increase car safety and road safety overall. They help the driver in the driving process to enable safe and relaxed driving. Some examples of driver assistance systems that maximize safety include antilock braking systems, adaptive cruise control, blind spot detection, driver drowsiness detection, electronic stability control, emergency braking systems, hill descent control, intelligent speed assistance, lane departure warning systems, pedestrian detection, rear cross traffic alert, and traffic sign recognition. These systems alert drivers to hazards, help maintain safe distances and speeds, and in some cases automatically apply brakes to avoid collisions.

Blind spot detection with automatic steeringeSAT Journals
Abstract Present days, the automotive industry is mainly focusing on the road safety measures. The automobiles have been constantly updating with new sensing technologies to detect blind spots, which can prevent road accidents. Almost 1.32 million people die in road accidents each year. Blind spot of an automobile is the region of the vehicle which cannot be observed properly while looking either through side or rear mirror view. To meet the above requirements, this paper describes detecting blind spot by using ultrasonic sensor and controlling the direction of car by automatic steering. The technology embedded in the system is capable of automatically steer the vehicle away from an obstacle if the system determines that a collision is impending or if the vehicle is in the vicinity of our car.

Accident Alert System using Advance Microcontrollerijtsrd
In India most of the accidents are happening due to vehicles over speeding. Sometimes if obstacle is close to the vehicle then they won't be able to judge the distance to apply instant brakes and accident is occurred. To avoid accident due to over speeding, obstacle detection using ultrasonic sensors is used. In this project ultrasonic sensor is used for 360degree detection of obstacle. If obstacle is in front of the vehicle less than safety distance, automatically brakes will be applied or if vehicle comes from backside of the vehicle and is at less than safety distance then the warning light is shown to vehicle. Sometimes if vehicle is coming very close to our vehicle just before hit the vehicle the airbags are open.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
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.
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.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
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%.
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.

3. Overview:
Automatic braking is a technology for automobiles to sense and
avoid an imminent collision with another vehicle, person or
obstacle by braking without any driver input. Sensors to detect
other vehicles or obstacles can include radar, video, infrared,
ultrasonic or other technologies. Automatic braking technologies
combine sensors and brake controls to help prevent high speed
collisions. Some automatic braking systems can prevent
collisions altogether, but most of them are designed to simply
reduce the speed of a vehicle before before it hits something.
Since high speed crashes are more likely to be fatal than low
speed collisions, automatic braking systems can save lives and
reduce the amount of property damage that occurs during an
accident. Some of these systems provide braking assistance to
the driver, and others are actually capable of activating the
brakes with no driver input.
4. Methodology:
A transceiver placed at the front of the car first emits ultrasonic
waves which propagate and reflect back after colliding with the
obstacle in the way, this signal is sensed and processed by
receiver, microprocessor placed in respectively that is
programmed to signal or apply the breaks by the help of
mechanical mechanism provided in the car.
The safe distance will be programmed into the commands of
microprocessor that will only apply breaks if the body lies
within the specified range
Breaks are applied by the help of electric motors provided in OR
by Blocking the commands in the car to move towards the
obstacle without turning the car. There will be first stop of the
electric current to the motors in the car than application of
retarding break bushes.
5. Components Used
Ultrasonic Sensor ( transmitter and receiver )
Microprocessor ( ARDINO 69 )
Electric Wirings
Electric motor
Bread board
Transducer
Electrical resistor
Prototype Car (Toy Car)
7. Extension of the system:
When this system is to be applied in roadsters it should work
more than what it’s operation was in prototype. Like in roadsters
the breaks are to be applied by the help of hydraulic breaks that
should be stressed as done by the help of paddle. Also the sensors
are not to be activated all the time cause it may cause
inconvenience while moving through parking lots , etc.
There will be addition of wheel speed sensor that will activate the
remaining ABS (Auto break System).
There can also be a notification to the driver about the presence of
obstacle in front of the vehicle.
9. Significance of the System
The importance of this system can be figured out by the help of
following statistics that
Only 40% of the drivers applied breaks in an accidental
situation.
There were casualties about 2.6 millions last year due to front
end vehicle collision.
Laboratory test results has proved that about 47% of the
collision impact can be reduced by automatically application
of the break forces.
