Four Stroke Engine
The document describes the four stroke engine cycle. A four stroke engine uses intake, compression, power, and exhaust strokes to complete one cycle. During the intake stroke, the intake valve opens and the piston moves down to draw air-fuel mixture into the cylinder. In the compression stroke, both valves are closed and the piston moves up to compress the mixture. The power stroke occurs when the compressed mixture is ignited, pushing the piston down. Finally, in the exhaust stroke, the exhaust valve opens and the piston pushes out the exhaust gases. The four stroke cycle is more efficient but more complex than a two stroke engine.

Two stroke cycle engine
- Two-stroke engines complete the combustion cycle in two strokes of the piston rather than four strokes, as in four-stroke engines. They rely on crankcase compression or a blower to induct fresh air and remove exhaust gases, rather than separate intake and exhaust strokes.
- There are different types of two-stroke engines based on the scavenging method (crankcase or separately scavenged), scavenging process (cross flow, loop, uni-flow), and port timing (symmetrical or unsymmetrical).
- In a crankcase-scavenged engine, the piston helps induct fresh air into the crankcase and transfers it into the cylinder, where it scavenges out exhaust gases

Working of four stroke petrol engine and comparison between petrol and diesel...
This document summarizes the key differences between a 4-stroke petrol engine and diesel engine. It describes the 4 strokes - suction, compression, power, and exhaust. The Otto cycle used in petrol engines involves constant volume combustion, while the Diesel cycle uses constant pressure combustion. The main differences are that petrol engines use a spark plug for ignition, have a lower compression ratio of 7:1-12:1, and admit fuel and air during the suction stroke, while diesel engines auto-ignite due to high compression of 16:1-22:1 and admit only air during suction. Diesel engines are generally more efficient but heavier than petrol engines.

IC ENGINES
I.C engines are heat engines where combustion of fuel occurs inside the engine. There are two main types - spark ignition engines which use a spark plug to ignite an air-fuel mixture, and compression ignition engines where high compression ignites the fuel, such as diesel engines. The basic components of an I.C. engine include the cylinder, piston, combustion chamber, valves, and crankshaft which converts reciprocating motion to rotational motion. Spark ignition engines have a lower compression ratio compared to compression ignition engines and use petrol as fuel.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
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%.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Low power architecture of logic gates using adiabatic techniques
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.

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.
