The document presents information on Gigabit Fidelity (Gi-Fi), a next generation wireless technology that allows data transfer rates up to 5 gigabits per second over short ranges of around 10 meters. Gi-Fi operates at 60 GHz frequencies using time-division duplex to transmit and receive data. It was developed by Professor Stan Skafidis as an improvement over existing wireless technologies like Bluetooth and Wi-Fi that have lower data rates and power consumption. The document discusses Gi-Fi's architecture, working mechanism, advantages, applications and future scope. It is expected to become the dominant wireless networking technology within five years.
what is gifi?
GIFI stands for General Index of Financial Information.
The GIFI is a system that assigns a unique code to a list of items commonly found on income statements, balance sheets, and statements of earnings.
The purpose of the GIFI is to allow the CRA (Canada Revenue Agency) to collect and process financial information more efficiently. For instance, the GIFI lets the CRA validate tax table information electronically rather than manually.
GI-FI (Gigabit Fidelity) or Giga bit wireless refers to wireless communication at a data rate of more than one billion bits (gigabits) per second. GI-FI offers some advantages over WI-FI, a similar wireless technology. In that it offers faster information rate in GBPS, less power consumption and low cost for short range transmission as compare to current technology. GI-FI consists of a chip which has facility to deliver short-range multi gigabit data transfer in a local environment and compared to other technologies in the market it is ten times faster. GI-FI has the data transfer speed up to 5 GBPS within a short-range of 10 metres. It operates in 60 GHZ frequency band. GI-FI is developed on an integrated wireless transceiver chip. It has both transmitter and receiver, integrated on a single chip which is fabricated using the CMOS (complementary metal oxide semiconductor) process and it also consists of a small antenna. GI-FI allows transferring large videos, audio files, data files etc. within few seconds.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

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.

• Optical fibers played a dominant role for its
higher bit rates and faster transmission.
• But the installation of cables caused a
greater difficulty and thus led to wireless
access.

11. Architecture of Gi-Fi
The core component of a Gi-Fi system is
the subscriber station.
It supports standard of IEEE 802.15.3C Wireless
PAN.
An 802.15.3C based system often uses small
antenna at the subscriber station.
It supports line of sight operation.

13. Working of Gi-Fi
Use Time Division Duplex for both transmission and receiving.
Data files are up converted from IF range to RF60 Ghz range
by using 2 mixers.
• Fed this to a power amplifier, which feeds millimeter wave
antenna.

14. Working of Gi-Fi (Cont.)
The incoming RF signal is first down converted to an IF signal
centered at 5 GHz and then to normal data ranges.

15. Time-division Duplex
Time-Division Duplex (TDD) is the application
of time-division multiplexing to separate
outward and return signals.

17. Ultra Wide Band Frequency Usage
Technology with high bit rate, high security and
faster data transmission.
Ultra-Wideband (UWB) is a technology for
transmitting information spread over a large
bandwidth (>500 MHz) that should, be able to share
spectrum with other users.

18. Advantages of Gi-Fi
• High speed of data transfer
• Low power consumption
• High security
• Cost effective
• Small size
• Highly portable

22. Conclusion
The Gi-Fi integrated transceiver chip will be launched by
starting of next year by NICTA, Australia.
Due to less cost of chip so many companies like Intel, LG,
Matsushita (Panasonic), NEC, Samsung, Si-BEAM, Sony
and Toshiba etc. are looking forward to launch with lower
cost.
Within five years, we expect GiFi to be the dominant
technology for wireless networking.
