Curvilinear motion occurs when a particle moves along a curved path.
Since this path is often described in three dimensions, vector analysis will
be used to formulate the particle's position, velocity, and acceleration

"Pavement condition measurement at high speed using a TSD" presented at ESREL...TRUSS ITN
Abstract: The aim of this paper is to present the latest developments in the use of an instrumented vehicle called the Traffic Speed Deflectometer (TSD). A large axle load is applied to the pavement under the TSD. The deflection caused by this axle load is measured using several Doppler lasers. In the first step, the velocity of the deflection of the pavement is measured which can be shown to be proportional to the slope of the deformed profile. The pavement deflection is calculated in the second step using an integration model. A Winkler model is used to simulate the pavement behaviour under the axle load and the TSD is represented as a half-car model. The TSD is shown to be an effective tool for pavement damage detection.
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.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Particle Motion and Choice of
Coordinates:
Assume P is a particle moving along some
general path in space.
Position P at any time, t can be describe
through:
Rectangular coordinates x,y,z
Cylindrical coordinates r,θ,z
Spherical coordinates R,θ,ϕ
Tangent, t and normal, n to the curve

RECTILINEAR KINEMATICS: CONTINUOUS MOTION
A particle travels along a straight-line path
defined by the coordinate axis s.
The total distance traveled by the particle, sT, is a positive scalar that
represents the total length of the path over which the particle travels.
The position of the particle at any instant,
relative to the origin, O, is defined by the
position vector r, or the scalar s. Scalar s can
be positive or negative. Typical units for r
and s are meters (m).
The displacement of the particle is defined
as its change in position.
Vector form: r = r’ - r Scalar form: s = s’ - s

VELOCITY
Velocity is a measure of the rate of change in the position of a particle.
It is a vector quantity (it has both magnitude and direction). The
magnitude of the velocity is called speed, with units of m/s.
The average velocity of a particle during a
time interval t is
vavg = r / t
The instantaneous velocity is the time-derivative of position.
v = dr / dt
Speed is the magnitude of velocity: v = ds / dt
Average speed is the total distance traveled divided by elapsed time:
(vsp)avg = sT / t

ACCELERATION
Acceleration is the rate of change in the velocity of a particle. It is a vector
quantity. Typical units are m/s2.
As the book indicates, the derivative equations for velocity and acceleration
can be manipulated to get a ds = v dv
The instantaneous acceleration is the time
derivative of velocity.
Vector form: a = dv / dt
Scalar form: a = dv / dt = d2s / dt2
Acceleration can be positive (speed increasing)
or negative (speed decreasing) or zero (constant
speed)

SUMMARY OF KINEMATIC RELATIONS:
RECTILINEAR MOTION
• Differentiate position to get velocity and acceleration.
v = ds/dt ; a = dv/dt or a = v dv/ds
• Integrate acceleration for velocity and position.
• Note that so and vo represent the initial position and velocity of
the particle at t = 0.

Graphical Interpretations:
From (a), any slope of the line is v = (ds/dt)
From the slope data, can plot the v versus t graph.
From (b), any slope of the line is a = (dv/dt)
From the slope data, can plot the a versus t graph.
Area under the curve (b), during dt time is v dt. Which is
the displacement of ds.
Area under the curve (c), during dt time is a dt. It is the
net change in velocity.

Graphical Interpretations:
Area under the curve during ds displacement is
a ds. Since a ds = v dv = d (v2/2). So, area
under the curve from s1 to s2 is:
When v is plotted against s, slope of the curve at
any point A is dv/ds. Having AB normal to the
curve result in CB/v = dv/ds. So, CB = v(dv/ds)
= a.
All graph should have similar numerical scale.

CONSTANT ACCELERATION
The three kinematic equations can be integrated for the special case when
acceleration is constant (a = ac) to obtain very useful equations. A common
example of constant acceleration is gravity; i.e., a body freely falling toward
earth. In this case, ac = g = 9.81 m/s2 downward. These equations are:

EXAMPLE
Plan:Establish the positive coordinate, s, in the direction the
particle is traveling. Since the velocity is given as a function
of time, take a derivative of it to calculate the acceleration.
Conversely, integrate the velocity function to calculate the
position.
Given: A particle travels along a straight line to the right
with a velocity of v = ( 4 t – 3 t2 ) m/s where t is
in seconds. Also, s = 0 when t = 0.
Find: The position and acceleration of the particle
when t = 4 s.
