An active suspension system uses sensors, an electronic control unit, actuators, and adjustable shocks and springs to improve ride control, height control, roll control, dive control, and squat control compared to a conventional passive suspension system. The active suspension system mimics the functions of the human body to reduce sway and rolling, improve handling, and provide a more comfortable ride compared to adding extra springs. While complex control algorithms and increased costs present drawbacks, active suspension systems are expected to become more common as technology advances.

Electronic controlled Automotive chassis and drive train.pptxMulualem Yimer
The term "chassis" is used to designate the complete car minus the body.
The chassis therefore consists of the engine, power-transmission system, and suspension system all suitably attached to, or suspended from, a structurally independent frame.
The drivetrain includes the transmission, the driveshaft, the axles, and the wheels.
The main function of the drivetrain is basically to convey power from the vehicle’s engine, through the transmission to the drive wheels on the vehicle to control the amount of torque.
An overview of embedded systems in automobilesLouise Antonio
This presentation on the applications of embedded systems in automobiles focusses on the two most prevalent and sought about technologies- ABS and ACC with collison avoidance, the biggest motivation being that these technologies save lives.This discusses the doppler shift in detail.
Traction control basically reduces the slip of the tires on icy surfaces when the car begins to accelerate and prevents wheels to spin. It uses a part of anti-lock braking system (ABS). There are certain indications which warn you to activate and deactivate traction control. While on snow, you should follow some warning signs and drive accordingly.
Saudi Arabia stands as a titan in the global energy landscape, renowned for its abundant oil and gas resources. It's the largest exporter of petroleum and holds some of the world's most significant reserves. Let's delve into the top 10 oil and gas projects shaping Saudi Arabia's energy future in 2024.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
7. Functions of Active Suspension
Improves driver control, safety and stability, with or
without a load .
Eliminates sway and reduces roll on corners
Reduces axle wrap
Maximum safety
Absorbs load, rather than resisting it, thereby
ensuring a much more comfortable ride
Eliminates the need for fitting extra blades which
harden the ride
Better handling and control in windy and rough road
conditions
Minimize wear on tires, shocks, shackles and leaf
springs
11. Active suspension mimics the
functions of the human body
The sensors are nerve ends
The Electronic Control Unit represents our
mind
Wires connecting the whole thing are the
central nervous system
The servos and actuators resemble the muso-
skelatel portion .
14. Draw-backs
Need for a large external power source
Complex control algorithms
Complex closed-loop control systems.
Requirement of fast-acting devices
Increased cost
15. Conclusion
In the case of active suspension
system, as in any other innovations of
automotive technology, today's innovation is
tomorrow's standard feature. Inspite of its high
initial cost, let us expect to see them in the
Indian roads soon. The trickle-down effect
will take some time, but it'll happen and when
such a time comes we can expect much lesser
accidents, less fatalities and more comfort in
driving the roads.
