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.

6. AGENDA
1. Overview - Segmental Plate Products for Buried Bridges
2. Buried Bridge Structural Design – Section 7 CSA S-6 CHBDC
3. Design Life - Designing for Durability
4. Projects and Applications
15. STRUCTURAL DESIGN
Buried structures
• two distinctly different materials that interact to
create a complex composite geo-structural
system to support the overburden and surface
live loads
1. Soils encasing the buried shell
2. Corrugated Steel Shell
16. BURIED STRUCTURE COMPONENTS
16
• Soil Component:
– engineered granular
backfill envelope
– materials of known
geotechnical properties
• Steel Component:
– Corrugated steel shell
– Corrugated shell is highly
efficient member to
support axial
compressive loads
• Net Result:
– economical buried
structure capable of
supporting large gravity
loads
17. STRUCTURAL DESIGN
Load resistance of the composite system
• highly influenced upon the geotechnical
properties of the backfill materials encasing the
buried structure
Strength of the structure is dependent upon
• Geometry of the buried steel shell
• Stiffness /thickness of the selected plate
corrugation .
18. STRUCTURAL DESIGN
Force Analysis
• Determine thrusts, moments and deflections
during and post construction
Strength Analysis
• Determine resistance of the structure to
support the calculated load effects
Successful Design ensures:
Resistance > Demand
19. STRUCTURAL DESIGN
Load Definitions
Dead Loads
• Weight of the soil column directly above the
footprint of the structure
• Weight of the shell is included in FEA
• Accurate soil densities are critical
• Deep bury applications DL account for 100%
of applied loads
20. STRUCTURAL DESIGN
Live Loads (Surface Pressure)
• Position as many axles of the design
vehicle at the road surface above the
conduit span
• Distribute rectangular surface pressure
through the overburden @ 1:1 in
transverse direction, 2:1 in longitudinal
direction
24. 250 TONNE HAUL TRUCK LIVE LOAD
12.4 M SPAN X 5.6 M RISE BRIDGE-PLATE ARCH
25. STRUCTURAL DESIGN
Earthquake Loads
– Earthquake loads are limited to determining an
additional thrust component known as TE
– TE is equal to a percentage of the Dead Load Thrust
(TD)
– The percentage multiplier (AV) equals 2/3 of the
horizontal ground acceleration ratio AH
– Earthquake thrust is then summed with Dead Load
Thrust (TD) x load factor
– TE does not have to be considered with any other
load combinations
