This project is studying a double lane change maneuver according to ISO 3888 standard using a rigid vehicle model and non-predictive driver model. The vehicle speed is 80 km/h and the lane change should be followed without touching the lanes. Furthermore, the width of the lanes are given as a function of the vehicle width. A driver model is adopted which is represented by servomechanism having the yaw angle Ψ as input and the steering angle δ as output which is proportional to the error between the effective Ψ and the angle of the trajectory. The transfer function between the output δ and the input Ψ in the Laplace domain is given by the driver gain, the delay of the driver and the Laplace variable. Hence, the stability of the vehicle can be analysed plotting Root loci for different values of driver gain and driver delay. Side slip angle of the vehicle β, steering angle δ and yaw rate as a function of the time will be derived while the trajectory is plotted in XY plane.

In daily life we can observe the difficulties of carrying the patients, old people, physically handicapped in public places like airports, railway stations, bus stands, hospitals, college campuses etc. To aid such people we prepared an electric tri-car to ease the task of carrying them. Moreover, it is a multipurpose vehicle to carry pilgrims in pilgrim places, to carry inspection teams in industries, estates or campuses etc. The seating arrangement of this tri-car is such a way that the disabled can easily get into the vehicle and also get down. This tri-car is designed and analyzed with the help of the soft ware called PROE. Then analysis is done in Statistical and Modal Analysis. We modeled and fabricated a tri-car into a three wheeled electric powered vehicle with three seats and can accommodate two pillions and a driver. We designed the vehicle to be propelled by an electric hub motor mounted in the front wheel and powered by 48V Lithium-ion battery.

Calculations were done to select these components based on the vehicle's specifications and performance requirements. These include calculating the required tractive force based on rolling resistance, aerodynamic drag, and other factors. The motor was then sized to provide this force. The battery capacity was selected to provide sufficient power for the motor. Testing showed a gear ratio of 1.54 provided optimum balance of torque and speed. Converting the scooter to electric reduces air pollution and operating costs compared
The document describes a hardware project to design a speed breaker power generation model using a rack and pinion arrangement. It includes 6 team members and their guides. The project aims to convert the kinetic energy of passing vehicles into electrical energy. It works by using the rack and pinion mechanism to convert vehicle movement into rotational motion that turns a generator to produce electricity stored in a battery. The major components, design specifications, theoretical power calculations, experimental results and advantages are provided.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

2. Introduction to Project
I begin this section with the statement of my project topic, the
project I have embarked upon is called ‘The Development and
Performance Evaluation a DC Electrical Powered Shopping Cart’
The DC electrically powered shopping cart that will be used in
holding the items of shopper in a shopping mall not require
excessive amount of push (Human Effort) to move items from
one point to another in a shopping mall by having a motor
attached beneath it and at the push of a button on the handle,
the motor spins causing forward movement, eliminating the need
of actually pushing the cart with much physical strength.
The Target audience for usage is shoppers and shopping malls
3. Aim and Objectives
Aim
The aim is to develop and carry out performance evaluations
(test) of a dc powered electrical shopping cart
Objectives
The objectives of this project are the goals of the project and
these include.
1. Develop and Fabricate an effectively working D.C. Electrical
shopping Cart
2. The shopping cart should be effective enough to carry the
maximum load requirements with minimum or no lag.
3. The shopping cart should be aesthetical pleasing to sight
4. To push the boundaries of technological achievement in
Nigeria
4. Scope/Areas of Coverage
To achieve the aims and objectives of the project the following
areas of action will be carried out
a. Drawing of the DC electrically powered shopping cart using
both hand sketches and final design with computer software
b. Suitable material selections for the DC electrically powered
shopping cart
c. Load carrying ability of the shopping cart calculations and
possible re-selection of material and dimension re-scaling
d. Fabrication of the DC electrically powered shopping cart
e. Electrical motor design and construction for the DC electrical
shopping cart
f. Actual physical testing of the DC electrical shopping cart i.e.
performance evaluation
5. Methodology
In this section I list the sequential steps that are intended to be
followed for the successful development of the DC electrically powered
shopping cart
Design of the structural
layout of the DC powered
shopping cart
The frame of the cart is
fabricated by welding the
different metallic parts
together
The batteries, motor and
wheel, chainlink
assembly are attached to
the bottom of the cart
Wires are passed through
the handles of the cart to
connect to the switch
The project is spray
painted upon
completion.
The project is covered in
ply-wood and then the
wood is spray painted to
give aesthetical finish
6. Progress Made So-Far
The activities I have carried out so far towards the completion of the DC electrically powered shopping
cart are represented with the chart below
The results of the activities are discussed in the next slides.

10. Results (3)
From the table aluminium is the selected material, depending on
stress strain calculations to ensure the fidelity of aluminium as a
viable material for the component it will be used as
The entire mass of the DC electrically powered shopping cart is
30kg.
The fully loaded mass of the cart is 80kg. Hence an electrical
motor that can carry a mass 80kg effectively without slipping is
going to be used
11. Results 4
