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.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

3. Introduction
What is Photo Electric Effect ?
During his experiment on EM waves, Hertz
noticed that sparks occurred more readily in
the gap of his transmitter when ultraviolet
light was
Directed on one of the light balls. He didn't
follow up this observation, but others did.
They soon discovered that the cause was
electrons emitted when the frequency of light
was sufficient high.
When a beam of light of sufficiently high
frequency onto a clean metal surface then the
light will cause electrons to leave the surface.
4. Definition:
The phenomenon of emission of electrons by the
metals when they are exposed to light of suitable
frequency is called as the photo electric effect and
emitted electrons is called as photoelectrons.
Photon Absorption: Light, made of photons, hits a
material, and electrons in the material absorb individual
photons.
Emission of Electrons: If absorbed photon energy is
sufficient, electrons overcome the material's binding
energy and are ejected, emitting photoelectrons.
Threshold Frequency: Electrons are emitted only if light
exceeds a specific frequency (threshold), related to the
minimum energy needed to free an electron.
Instantaneous Emission: Photoelectrons are emitted
instantly when the material is exposed to light of the
right frequency, with no delay. The emitted electrons'
number is proportional to light intensity.
Photo Electric Effect
5. Photon
In 1905, Einstein proposed the idea that light is
composed of discrete energy packets called photons.
This concept challenged the classical view of
continuous light waves.
Einstein's theory suggested that light energy is
emitted not continuously but in distinct amounts
known as quanta or quantum of energy.
Each photon carries a specific amount of energy,
marking a departure from the smooth and
continuous energy transfer associated with classical
wave theory.
The quantum nature of light explained phenomena
such as the photoelectric effect.
Einstein's work laid the foundation for quantum
mechanics, transforming our understanding of the
dual nature of light.
6. Energy of Photon
According to Einstein, each photon
of a light wave of frequency has the
energy E is given by,
E = h ⋅ ν (1)
Where,
E = energy of photon (joule)
h = planks constant - 6.626 x 10 - 34 J.s
v = frequency of photon(Hz)
7. Properties of Photon
A photon does not have any mass.
A photon does not have any charge
and are not deflected in electric field
or magnetic field.
All the quantum numbers are zero
for a photon.
n empty space, the photon moves at
speed of light.
In the interaction of radiation with
matter, radiation behaves as if it is
made up of particles called photons.
8. Construction and Working
The Hertz experimental set up used
for studying the photoelectric effect
is shown in above fig.
The set up consist of an evacuated
glass tube that has a photosensitive
metal plate C and another metal plate
A as shown. A monochromatic light
source emerging from the source S of
sufficiently short wavelength enters
the glass window W and fall on
photosensitive plate C, is called
emitter.
9. Photoelectric effect-working
when a beam of light fall on photosensitive metal plate c
which is called emitter.
The plate c emits photoelectrons due to photoelectric
effect. The photo electrons emitted by plate will be
attracted towards the positive plate.
these electron flows in the eternal circuit to cause an
electric current in the circuit.
Such a current is known as the photoelectric current and
measured by the micrometer connected in the circuits
10. Mathematical Description
Maximum K.E of ejected electron is given by,
Kmax = hν – φ
Where,
H = planks constant
V = frequency of incident photon
φ = work functionWhere
Vo= frequency for metal
So,
Kmax = h (v - vo )
K.E is +ve so we must have v > vo foe the photoelectric effect
to occur.
