The electricity supply industry is undergoing a profound transformation worldwide. Market forces, scarcer natural resources, and an ever-increasing demand for electricity are some of the drivers responsible for such unprecedented change. Against this background of rapid evolution, the expansion programs of many utilities are being thwarted by a variety of well-founded, environment, land-use, and regulatory pressures that prevent the licensing and building of new transmission lines and electricity generating plants.

Wireless power transmission technology is not a new technology. In 1980, it was demonstrated by Nikola Telsa. ... The name wireless power transmission states the transfer of electrical power from a source to an electrical device without the help of wires. Basically, it involves two coils: a transmitter and a receiver coil.
Wireless transmission of electricity development & possibilitychandan kumar
One of the major issue in power system is the losses occurs during the transmission and distribution of electrical power.
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.
Any problem can be solved by state–of-the-art technology.
Microwave Power Transmission is one of the promising technologies and may be the righteous alternative for efficient power transmission.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

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.

Advantages And Disadvantages Of WPT
Conclusion
4. INTRODUCTION
Wireless power transfer (WPT) or electromagnetic power transfer is the
transmission of electrical energy without wires.
Nicole Tesla was the first one to introduce the wireless power transfer In
1891, he began his work on wireless power transmission a this laboratory
in Colorado, USA.
Tesla’s successful experiment was the first demonstration of wireless
power transfer concept The Wardenclyffe tower.
5. BASIC PRINCIPAL OF WPT
By converting the AC Power to DC Power Using Rectifiers And Filters and then
again converting it back to AC at high frequency using inverters.
This low voltage high frequency Ac Power then passes from the transformer
primary to its secondary and is converted to DC Power Using rectifier, filter and
regulator arrangement.
6. MOTIVATION FOR WPT
Increase the device mobility
Avoid the wiring Hazards , Cost & isolation
Improve electric vehicles reliability
Enhance the research of biomedical Maintenance free and no
electrical plugs
7. TYPES OF WIRELESS POWER TRANSFER
Inductive Coupling WPT
Magnetic Resonance Inductive Coupling
Wireless Power Transfer Using Microwaves
Power Transfer by Laser
Wireless power techniques mainly fall into four categories
9. In inductive coupling (electromagnetic induction) or inductive power transfer,
IPT), power is transferred between coils of wire by a magnetic field
It is used in near field power transmission such as electric toothbrushes .
INDUCTIVE COUPLING
11. Stands for rectifying antenna
Consists of mesh of dipoles and diodes
Converts microwave to its DC equivalent
Usually multi-element phased array
RECTENNA
12. SOLAR POWER SETELLITE (SPS)
To provide energy to earth’s increasing energy need
SPS are placed in geostationary orbits
Each SPS may have 400 million photocells
Efficiency exceeds 95% if microwave is used
mMicrowave emitter
Satellite
earth
Solar panel
Receiver
13. POWER TRANSFER BY LASER
The power is beamed at a receiver that can convert it to electrical
energy known as 'power beaming‘
The visible region of the spectrum (tens of micrometers to tens
of nanometers).
High efficiency photo voltaic cells are used to convert the received laser
beam back into electricity.
14. TYPES OF WPT Distance between
transmitter and receiver
circuits
EFFICIENCY
Inductive Coupling a few millimeters Low
Magnetic Resonance a few meters High
Microwaves up to 100 kilometers High
Laser a few meters but could
be used for longer
distances by using high
intensity beam
Low
COMPARISON OF DIFFERENT WPT METHODS
15. REZENCE STANDARD
Rezence is a newly-developed wireless power transfer
standard introduced by Alliance for Wireless Power.
on magnetic resonance technology to transfer power
between a power transmitter and a power receiver.
This standard is developed to provide more features than
the Qi Standard.
17. No Wires
No E-waste
Efficient Energy Transfer
Unaffected By Day-night Cycle, Weather Or Season
ADVANTAGE
18. Initial Cost Is High.
High- Frequency Signal Must Be The Supply.
Maintenance Is Complicated
DISADVANTAGE
19. FUTURE APPLICATION
Charging portable devices (Qi), biomedical implants, electric vehicles,
powering buses, trains, smartcards.
Solar power satellite, powering drone aircraft, charging wireless devices.
Powering drone aircraft, powering space elevator climbers
Wireless parking charger.
20. Based on this study, we can say that the magnetic resonance WPT is the
most promising technique for powering devices wirelessly with high
efficiency over up to few meters. Being safe A for humans and environment,
magnetic resonance WPT can spread to be the standard charging method for
most portable devices in the next few years
