In conclusion, the document argues that wireless charging is a reality that can help address energy and environmental issues.
Now a days world is shifting towards electrified mobility to reduce the pollutant emissions caused by nonrenewable fossil fueled vehicles and to provide the alternative to pricey fuel for transportation. But for electric vehicles, traveling range and charging process are the two major issues affecting it’s adoption over conventional vehicles.
With the introduction of Wire charging technology, no more waiting at charging stations for hours, now get your vehicle charged by just parking it on parking spot or by parking at your garage or even while driving you can charge your electric vehicle. As of now, we are very much familiar with wireless transmission of data, audio and video signals so why can’t we transfer power over the Air.
Wireless charging using electromagnetic induction, and resonance magnetic coupling. Effects and limitations, cheallenges faced and meathods to overcome. Success Case study. References included.

Railway Electrification -
Electricity is used to eliminate smoke and take advantage of the high efficiency of electric motors; however, the cost of railway electrification means that usually only heavily-used lines can be electrified.
the power for electric locomotives can come from clean and/or renewable sources, including geothermalpower, hydroelectric power, nuclear power, solar power and wind turbines.
Electric locomotives benefit from the high efficiency of electric motors, often above 90%. Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put some power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking.
Thank you.

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.

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.

2. INTRODUCTION
The eco-friendly vehicle is the global trend in the automobile industry.
The electrical vehicle (EV) is the most suitable alternative of petroleum
vehicles.
The large capacity, weight, expensive price, short life time, and charging time
of battery obstruct the commercialization of EV.
To solve these problems, wireless charging of electric vehicle is
introduceded.
3. WHAT ARE EVS (ELECTRIC VEHICLES) ?
An electric vehicle (EV) uses one or more electric motors for propulsion.
An electric vehicle may be powered through a collector system by electricity from off-
vehicle sources, or may be self-contained with a battery or generator to convert fuel to
electricity.
EVs include road and rail vehicles, surface and underwater vessels, electric aircraft and
electric spacecraft.
4. NEED FOR EVS
Global Warming / Climate Change.
Rising Prices.
Acid Rain.
Effect on Human Health.
Impact on Aquatic Life by Oil Spills.
5. TYPES OF CHARGING SYSTEMS
Conductive Charging
It utilizes connector between
the Electric power source and
vehicle battery.
This type of charging is utilized
in Residential areas.
Inductive Charging
Wireless charging coupled with
magnetic resonance to transfer
power from a transmitting pad to
a receiving pad.
Battery Switching
Depleted EV battery pack
is switched with a fully
charged battery pack in
the switching station.
6. WHAT IS WIRELESS CHARGING ?
Wireless charging uses an electromagnetic field to transfer energy between two objects
through electromagnetic induction.
Energy is sent through an inductive coupling to an electrical device, which can then use that
energy to charge batteries or run the device.
7. i. As per studies, most electrical energy transfer is
through wires.
ii. Most of the energy loss is during transmission
iii. On an average, more than 30%
iv. In India, it exceeds 40%
8. HISTORY OF WIRELESS POWER TRANSMISSION
• In 1901, Nikola Tesla was able to transfer energy
from one coil to another coil wirelessly.
• 187 feet tall tower to broadcast energy
• He managed to light 200 lamps from a distance
of 40km.
• Due to shortage of funds, tower did not operate.
• The idea of Tesla is taken in to research after
100 years by a team led by Marin Soljačić from
MIT. The project is named as ‘WiTricity’.
9. HOW IT WORKS:
Specifically, the technology works by generating 20kHz frequencies into an electromagnetic
field by a power inverter which are embedded.
Wireless charging Electric Vehicles are built with an on-board pick up device that allows an
electric vehicle to be powered by an underground power line while driving.
This allows the vehicle to carry 4/5 less battery capacity or weight, because it only requires a
small battery for minimal operations off the power grid.
10. CONSTRUCTION OF A ROAD FOR OLEV
Electric power strips are buried 30 cm deep under the
road surface and connected to the power grid.
11.
12. ADVANTAGES:
80 % reduced operating cost than equivalent gas powered vehicles.
Lower maintenance costs than gas powered vehicles .
Pollution free.
Zero recharging time and unlimited range (when operating on an grid road).
Light weight vehicles.
A number of EVs can be charged at a time.
Electrically safe.
Charging is convenient.
13. DISADVANTAGES:
Initial installation cost is very high.
Working area is limited.
Currently the speed is limited to 40 miles per hour.
power outage might cause the EVs to run out of charge.
Heat generation is more than traditional charging.
Complex design.
Construction of wireless charging road is required
14. CONCLUSION:
Charging electric vehicles wirelessly- a reality.
Low maintenance cost but high initial cost.
Better then conventional wired system.
Energy crisis can be decreased.
Low power loss
In the future world will be completely wireless.
