Performance Analysis of WiMAX and LTE Using NS-2IJERA Editor
The increasing use of wireless devices and in particular smart phones has resulted the need for greater capacity
and higher speed than the existing network technologies. Hence, LTE (Long Term Evolution) and WiMAX
(Worldwide Interoper- ability for Microwave Access) became the two leading technologies. Services are
increasingly shifting from voice to data and from circuit-switched to packet-switched ones. Battle between LTE
and WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards
through IEEE 802.16 and is up and running but lacks in substantial roll out plans due to cost. The targets for
LTE indicate bandwidth increases as high as 100 Mbps on the downlink, and up to 50 Mbps on the uplink.
However, this potential increase in bandwidth is just a small part of the overall improvement LTE aims to
provide. This study illustrates the model and representation of LTE links and traffics using NS-2 network
simulator and observation of TCP performance investigated. The Evaluation of the network performance with
TCP is mainly based on congestion window behavior, throughput, average delay and lost packet.
What is “Last Mile Access”
It is the final leg of delivering connectivity from a communications provider to a customer. Usually referred to by the telecommunications and cable television industries. It is typically scene as an expensive challenge because “fanning out” wires and cables is a considerable physical undertaking.” (from Wikipedia)

Telecommunication Systems: How is Technology Change Creating New Opportunitie...Jeffrey Funk
These slides discuss how improvements in the data rates of wireline and wireless systems have and continue to occur. For wireline systems, these improvements are driven by the use of better glass fiber, lasers, amplifiers, and wavelength division multiplexing and there appears to be few limits to these improvements. For wireless systems, these improvements are primarily driven by the use of better ICs. As long as these improvements in ICs continue to occur, improvements in data rates along with improvements in the use of the frequency spectrum continue to be possible. Improvements in both wireless and wireline systems will also make new forms of Internet content possible. Furthermore, these improvements in ICs along with the improvements in MEMS that are discussed in a related set of slides are gradually making cognitive radio economically feasible. All of these improvements are creating various kinds of entrepreneurial opportunities. These slides are based on a forthcoming book entitled “Technology Change and the Rise of New Industries and they are the sixth session in a course entitled “Analyzing Hi-Tech Opportunities.”

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.
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.
