4G is a conceptual framework proposed in 2002 that aims to provide broadband Internet access to mobile devices at speeds up to 1Gbps. It utilizes an all-IP network architecture with packet-switched wireless connections. 4G supports interactive multimedia services through high-speed, high-capacity networks and seamless switching between network protocols. While 4G promises faster speeds and new applications, its implementation also faces challenges of high costs, increased battery usage, and requiring complicated new hardware.

5G wireless technology overview
شرح اساسيات الجيل الخامس من اجيال الاتصالات اللاسلكية ومقارنة بينه وبين الاجيال السابقة وكذلك متطلبات العمل على هذا الجيل الجديد
TeliaSonera was the first operator in the world to commercially launch 4G. It was in late 2009, in the city centres of Stockholm and Oslo. 4G is the short term for fourth-generation wireless. It is still a research lab standard , the stage of broadband mobile communications that will supersede the third generation (3G). It is expected that end-to-end IP and high-quality streaming video will be among 4G's distinguishing features.
A 4G system will be able to provide a comprehensive IP solution where voice , data and streamed multimedia can be given to the users on “ Anytime Anywhere ” basis and higher data rates than the previous generations.
It will be a fully IP based integrated system capable of providing between 100 Mbps to 1 Gbps in both indoor and outdoor with premium quality and high security.
It is going to be launched in the year 2010.

In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

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.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
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.

3. The first generation, 1G wireless mobile
communication systems, was introduced in the early
1980s. 1G wireless was analog and supported the
first generation of analog cell phones with the
speeds up to 2.4kbps.
The second generation, 2G system, fielded in the
late 1980s.It was planned mainly for voice
transmission with digital signal and the speeds up to
64kbps.
The third generation, 3G wireless system, also
called UMTS (Universal Mobile Telecommunications
Standard), was developed in the late 1990s .3G is
not only provided the transmission speeds from
125kbps to 2Mbps, but also included many
services, such as global roaming, superior voice and
4. To vanish the disadvantages of 3G, 4G came to the
communication world.
The fourth generation, 4G is a conceptual
framework just raised in 2002. The speeds of 4G
can theoretically be promised up to 1Gbps. The
beyond will be 5G with incredible transmission
speed with no limitation for access and zone size.
5. The process began with the designs in the 1970s that
have become known as 1G. The earliest systems
were implemented based on analog technology.
The 2G (second generation) systems designed in the
1980s were still used mainly for voice applications but
were based on digital technology, including digital
signal processing techniques.
The 2.5G it is basically an enhancement of the two
major 2G technologies to provide increased capacity
on the 2G RF (radio frequency) channels and to
introduce higher throughput for data service.
