Conclusion
NFC is wireless technology which provides communication between two mobile phones which
contain NFC tags, using short range radio waves. It uses the magnetic field induction for this purpose. Both devices can communicate with each other using NFC technology when they touch each other or brought very close to each other. It requires short range of approximately ten centimeters to perform the exchange of information between two devices.
We can do payment using our NFC enabled phone by swiping it out in front of the phone reader and then the purchase price will automatically paid from credit card or debit card. Our mobile phone can be used in place of wallet, credit cards, debit cards etc. We don’t need to carry our credit card or debit card with us. But with these advantages, we will have to face disadvantages too. There are some security threats to NFC technology, which should be prevented.
NFC technology uses RFID (Radio Frequency Identification) for data/information exchange between two devices over a short distance like Bluetooth and Wi-Fi technology. NFC enabled smartphone users can make transactions and access information with only a simple touch. NFC devices can send and receive data simultaneously. So this technology has a very bright future scope. Since it is a new technology, so NFC enabled mobile users need to be educated on how it will work for them to make payment or exchange any information. But there is a requirement of a protected infrastructure for NFC technology so that it could be widely adopted all over the world. This technology has several advantages over other wireless technology because it provides bidirectional communication for exchanging information.
For example if someone have a laptop and cell phone equipped with NFC, then he/she can easily download data from Internet into the cell phone by simply touching
the cell phone with laptop. Like that you may take pictures by the cell phone and if you want to show those pictures to your friends on big screen then you may just touch your phone with TV and show them. Or if you want to print those pictures then by touching the cell phone with NFC equipped printer will give you the prints of those pictures. This principle works with any kind of
devices equipped with NFC to communicate with each other.
It’s operating frequency is 13.56MHz. Working distance with compact standard antennas is up to 10 cm. The rate of transfer of data is around 106 to 424 Kbit/s. For two devices to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag.

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.

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.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

15. NFC SPECIFICATION
NFC operates at 13.56 MHz and at rates ranging from 106
kbit/s to 424 kbit/s.

20. ADVANTAGES OF NFC
Not restricted to 1-to-1 communication, it is 2-way
communication.
Multiple devices in a small area can communicate with each
other using the same frequency.
No special software is required.
Secure level is high due to encoding system.
High recognition speed and low recognition error.
No manual configuration and settings.
No search and pair procedure.
21. LIMITATIONS OF NFC
The system has the limitation that it can be operated only
with devices under a short range i.e around 10 cm.
The data transfer rate is very less at about 106kbps, 212
kbps and 424kbps.
22. CONCLUSION
Mobile handsets are the primary target for NFC and soon
NFC will be implemented in most handheld devices. Even
though NFC have the shortest range among radio frequency
technologies, combining them with existing technologies
like Bluetooth or Infrared can increase its range of
applications.
