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.

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. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

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.

4. INTRODUCTION
Zigbee is an emerging worldwide standard for
Wireless Personal Area Networks (WPAN).
Defined rate of 250 kbit/s on 2.4 Ghz frequency,
best suited for a single signal transmission from a
sensor or input device.
Network based on IEEE 802.15.4 standard.
low cost, low power, wireless mesh network
standard.
Applications include wireless light switches,
electrical meters with in-home-displays, traffic
management systems, and other consumer and
industrial equipment.
5. WHY WE NEED ZIGBEE!
There are many standards that address mid to high
data rates for voice, PC LANs, video, etc.
However, up till now there hasn’t been a wireless
network standard that meets the unique needs of
sensors and control devices.
6. USES
Home automation
Wireless sensor networks
Industrial control
Embedded sensing
Medical data collection
Smoke and intruder warning
Building automation
7. ZIGBEE DIVICES
Zigbee devices are of three types:
1) ZigBee coordinator (ZC)
The main device, the coordinator forms the network tree
and is a bridge to other networks. There is exactly one
ZigBee coordinator in each network it stores information
about the network, including acting as the Trust Center
& repository for security keys.
2) ZigBee Router (ZR)
As well as running an application function, a router can
act as an intermediate router, passing on data from
other devices.
3)ZigBee End Device (ZED)
Contains just enough functionality to talk to the parent
node (either the coordinator or a router); it cannot relay
data from other devices.
8. HOW ZIGBEE WORKS
It works in the unlicensed 2.4 GHz (worldwide), 915 MHz
(Americas and Australia) and 868 MHz (Europe) ISM bands.
Sixteen channels are allocated in the 2.4 GHz band, with each
channel requiring 5 MHz of bandwidth.
It is built on a single chip which reduces its cost and power
consumption.
It has few analog stages and uses digital circuits wherever
possible.
The radios use direct-sequence spread spectrum coding,
which is managed by the digital stream into the modulator.
Binary phase-shift keying (BPSK) is used in the 868 and 915
MHz bands, and offset quadrature phase-shift keying
(OQPSK) that transmits two bits per symbol is used in the 2.4
GHz band.
The current ZigBee protocols support beacon and non-beacon
enabled networks.
9. DATA RATE
Frequency Data Rate Indoor Outdoor
2.4Ghz 250kb/s 10 to 20m 1500m
915Mhz 40kb/s - 1000m
868Mhz 20kb/s - 800m
12. ZIGBEE NETWORK &SECURITY
ARCHITECTURE
ZigBee uses 128-bit keys to implement its security
mechanisms.
Initial master key must be obtained through a secure
medium (transport or pre-installation), as the security of
the whole network depends on it.
A secure network will designate one special device
which other devices trust for the distribution of security
keys: the trust center.
The MAC sub layer is capable of single-hop reliable
communications.
The network layer manages routing, processing
received messages and being capable of broadcasting
requests.
The application layer offers key establishment and
transport services to both ZDO and applications.
13. ADVANTAGES OF ZIGBEE
Low power consumption.
They are more ecological saving megawatts at its
full deployment.
Low cost (device, installation, maintenance).
High density of nodes per network(using IEEE
802.15.4 PHY and MAC).
14. SIMULATION OF ZIGBEE NETWORKS
NS2, OPNET, and NetSim can be used using C++.
Simulation on Opnet
