This document summarizes wireless power transmission using inductive coupling for different applications. It discusses how an alternating current in a transmitter coil generates a magnetic field which induces a voltage in a receiver coil. This induced voltage can be used to power mobile devices or charge batteries wirelessly. The document then reviews inductive coupling technology and compares various wireless power transfer methods. It presents practical results of a wireless mobile phone charger, LED lighting, and a DC fan operating without wires by using inductive coupling to transmit power. The document concludes that wireless power transmission through inductive coupling is an efficient means of transferring power without wires and has many potential applications.
Today large number of new technologies depends on electrical supply system, so complexity of
wires is very high. In this project, as requirement of wireless electrical power system, project
team present an analysis the concept of cable less transmission i.e. Power without the usage of
any kind of the electrical conductor or wires. Transmission or distribution of 50 or 60 Hz
electrical energy from the generation point to the consumers end without any physical wire has
yet to mature as a familiar and viable technology.
Our team chose to project the feasibility of wireless power transmission through
inductive coupling. This consists of using a transmission and receiving coils as the coupling
antennas. Although the coils do not have to be solenoid they must be in the form of closed loops
to both transmit and receive power. To transmit power an alternating current must be passed
through a closed loop coil. The alternating current will create a time varying magnetic field. The
flux generated by the time varying magnetic field will then induce a voltage on a receiving coil
closed loop system. This seemingly simple system outlines the major principle that our research
investigated. The primary benefits to using inductive coupling are the simplicity of the
transmission and receiving antennas, additionally for small power transmission this is a much
safer means of conveyance. To demonstrate the success of our the teams we created a receiving
circuit to maximize the amount of received power and light an LED at a distance up to two feet.
We were able to create both transmission and receiving circuits capable of transmitting the
necessary power to light an LED in a pulsed mode. On average with transmitting one watt of
power the receiving circuit was able to receive 100 micro-watts of power. While the efficiency of
the system is extremely low, approximately 0.01% with some improvements we feel certain the
efficiency could be greatly improved. Furthermore, as the transmission distance is decreased the
efficiency of any system using inductive coupling improves exponentially.
Wireless power transmission project is used to transfer the power from the power source to electrical loads using high frequency resonating air core transformers.

PROJECT DESCRIPTION
DOWNLOAD
The main objective of this project is to develop a device for wireless power transfer. The concept of wireless power transfer was realized by Nikolas tesla. Wireless power transfer can make a remarkable change in the field of the electrical engineering which eliminates the use conventional copper cables and current carrying wires.
Based on this concept, the project is developed to transfer power within a small range. This project can be used for charging batteries those are physically not possible to be connected electrically such as pace makers (An electronic device that works in place of a defective heart valve) implanted in the body that runs on a battery.
The patient is required to be operated every year to replace the battery. This project is designed to charge a rechargeable battery wirelessly for the purpose. Since charging of the battery is not possible to be demonstrated, we are providing a DC fan that runs through wireless power.
This project is built upon using an electronic circuit which converts AC 230V 50Hz to AC 12V, High frequency. The output is fed to a tuned coil forming as primary of an air core transformer. The secondary coil develops a voltage of HF 12volt.
Thus the transfer of power is done by the primary(transmitter) to the secondary that is separated with a considerable distance(say 3cm). Therefore the transfer could be seen as the primary transmits and the secondary receives the power to run load.
Moreover this technique can be used in number of applications, like to charge a mobile phone, iPod, laptop battery, propeller clock wirelessly. And also this kind of charging provides a far lower risk of electrical shock as it would be galvanically isolated.
It systems allow power to be transferred from one electrical network to another electrical network without need for wires or exposed contacts. There has been rapid expansion of WPT in mobile phone chargers and electric bulb and charging electric vehicles and dynamic charging electric vehicles, also called road powered electric vehicles. It is expected that WPT industry will grow persistently in coming decaded, commonly wireless power transfers are conducted using an inductive coupling and followed by magnetic induction , we use magnetic induction using copper wire with a diameter., The wireless power transfer field would be in high demand for electric power to be supplied in the future.

Development of a Wireless Power Transfer Circuit Based on Inductive CouplingTELKOMNIKA JOURNAL
Wireless electrical energy transfer has many advantages over the same through conducting
cables. This research focusses on developing wireless power transfer circuitusing inductive coupling. The
experiment has been done by changing the number of turns and the diameter of the wire of a coil with the
aim of finding the maximum power and the longest distancethat the energy can be transferred through
wireless means. The power source is connected to a series of electronics components and a copper coil
which form the primary source for the transmitter the power receiver consists of a copper coil, a rectifier
and the load. In a system with the diameter of the wires of the two coils is0.5 mm, and the number of turns
is 26 at the frequency of 470KHz the efficiency of power transfer about 1.51% at a distance of 1 cm.
The transferred energy by wireless means could operate a 1 Watt LED at 1 cm.
Project Power Shoe: Piezoelectric Wireless Power Transfer - A Mobile Chargin...Shayan Pervez
When a person walks, pressure is exerted on the
ground and this pressure can be converted into electrical energy
and it can be used to power electronic devices. In this paper a
Mobile charging system is designed. A piezo electric generator is
placed in the shoe. The power that is generated by piezo electric
generator when a person walks is transferred to the device by
using a mid-range wireless power transfer (WPT) which is a
Resonance coupling technique.
One of the major issue in power system is the losses occurs during the transmission and distribution of electrical power. As the demand increases day by day, the power generation increases and the power loss is also increased. The major amount of power loss occurs during transmission and distribution. The percentage of loss of power during transmission and distribution is approximated as 26%. The main reason for power loss during transmission and distribution is the resistance of wires used for grid. The efficiency of power transmission can be improved to certain level by using high strength composite overhead conductors and underground cables that use high temperature super conductor. But, the transmission is still inefficient. According to the World Resources Institute (WRI), India’s electricity grid has the highest transmission and distribution losses in the world – a whopping 27%. Numbers published by various Indian government agencies put that number at 30%,40% and greater than 40%. This is attributed to technical losses (grid’s inefficiencies) and theft. Any problem can be solved by state of the art technology. The above discussed problem can be solvedby choose an alternative option for power transmission which could provide much higher efficiency, low transmission cost and avoid power theft. Microwave Power Transmission is one of the promising technologies and may be the righteous alternative for efficient power transmission.

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.

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.

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.
