The document describes the four strokes of a diesel engine: 1) Intake stroke where only air enters the cylinder, 2) Compression stroke where the air is compressed to a high ratio above 1000 degrees F, 3) Power stroke where diesel fuel is injected and explodes to push the piston, and 4) Exhaust stroke where exhaust gases escape and the cycle repeats. The key differences from a gasoline engine are that diesels do not use spark plugs and have a much higher compression ratio, leading to better fuel efficiency.

Petrol engine vs diesel engine
Diesel engines differ from petrol/gasoline engines in that diesel engines ignite fuel via compression rather than with a spark plug. Diesel engines have higher compression ratios than petrol engines, ranging from 14:1 to 25:1. This makes diesel engines more efficient but also more expensive than petrol engines. While diesel engines have advantages like better fuel efficiency and reliability, they also have disadvantages like being noisier, producing more emissions, and being harder to start in cold weather. Both engine types are commonly used in vehicles, though diesel sees more use in larger transport like trucks and buses.

Stratified-charge-engine-ppt
A stratified charge engine provides a rich air-fuel mixture close to the spark plug to promote ignition, while using a lean mixture for the remainder of the cylinder. This allows for higher compression ratios and leaner mixtures than conventional engines, improving fuel efficiency. The overall air-fuel ratio can reach 40:1 to 50:1. While injectors increase costs, fuel efficiency gains are offsetting this. At high loads efficiency matches conventional engines due to a stoichiometric mixture. High variability can disrupt stratified mixture formation and reduce combustion if the rich area is not near the spark.
Development of Stratified Charge Engine
This document summarizes research on developing a stratified charge engine from a conventional spark ignition engine. A stratified charge engine creates a rich fuel-air mixture near the spark plug for ignition, while using a leaner mixture elsewhere in the combustion chamber. This improves fuel efficiency over traditional engines. The document discusses options for implementing charge stratification through fuel injection or carburetion methods. It also outlines modifications needed and results showing improved efficiency and reduced emissions compared to conventional engines. Barriers to implementation include potential power loss, increased weight and cost, and unproven reliability.

Distance Vector Routing
Distance vector routing is a routing protocol that determines the best route for data packets based on distance. Each router maintains a routing table with the minimum distances to every other node and periodically shares its table with neighbors. When a router receives an update indicating a change, it will recalculate its own routing table and propagate changes. While simple to implement, distance vector routing is prone to counting to infinity problems and slow convergence.

Applications of artificial Intelligence in Mechanical Engineering.pdf
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.
Redefining brain tumor segmentation: a cutting-edge convolutional neural netw...
Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

This document serves as a comprehensive step-by-step guide on how to effectively use PyCharm for remote debugging of the Windows Subsystem for Linux (WSL) on a local Windows machine. It meticulously outlines several critical steps in the process, starting with the crucial task of enabling permissions, followed by the installation and configuration of WSL.
The guide then proceeds to explain how to set up the SSH service within the WSL environment, an integral part of the process. Alongside this, it also provides detailed instructions on how to modify the inbound rules of the Windows firewall to facilitate the process, ensuring that there are no connectivity issues that could potentially hinder the debugging process.
The document further emphasizes on the importance of checking the connection between the Windows and WSL environments, providing instructions on how to ensure that the connection is optimal and ready for remote debugging.
It also offers an in-depth guide on how to configure the WSL interpreter and files within the PyCharm environment. This is essential for ensuring that the debugging process is set up correctly and that the program can be run effectively within the WSL terminal.
Additionally, the document provides guidance on how to set up breakpoints for debugging, a fundamental aspect of the debugging process which allows the developer to stop the execution of their code at certain points and inspect their program at those stages.
Finally, the document concludes by providing a link to a reference blog. This blog offers additional information and guidance on configuring the remote Python interpreter in PyCharm, providing the reader with a well-rounded understanding of the process.

Diesel engine-1 md.-shahidul-islam
- 1. Diesel Engine The only difference between diesel engine and a four-stroke gasoline engine is: •No sparkplug on Diesel engine. •Has a higher compression ratio. (14:1 to 25:1) •Better fuel mileage.
- 2. Diesel Engine Intake Stroke: •Piston moves from TDC to BDC creating vacuum in the cylinder •Intake valve opens allowing only air to enter the cylinder and exhaust valve remains closed
- 3. Diesel Engine Compression Stroke •Both valves stay closed •Piston moves from BDC to TDC, compressing air to 22:1 •Compressing the air to this extent increases the temperature inside the cylinder to above 1000 degree F.
- 4. Diesel Engine Power Stroke •Both valves stay closed •When the piston is at the end of compression stroke(TDC) the injector sprays a mist of diesel fuel into the cylinder. •When hot air mixes with diesel fuel an explosion takes place in the cylinder. •Expanding gases push the piston from TDC to BDC
- 5. Diesel Engine Exhaust Stroke •Piston moves from BDC to TDC •Exhaust valve opens and the exhaust gases escape •Intake valve remains closed
- 6. Diesel Engine Four Strokes of Diesel Engine
