An implementation of a reliable broadcast scheme for 802.11 using network coding

Creator:: Edgecombe, Richard
Abstract:: Forward Error Correction and retransmission are two approaches used to reliably broadcast data in a network with poor quality of service. Taking some assumptions, it has been suggested that a retransmission based reliable broadcasting scheme using network coding should in theory provide an increase in bandwidth efficiency by combining packets...

Multimedia streaming using multiple TCP connections

Creator:: Tullimalli, Sunand
Abstract:: Packet loss, delay and time-varying bandwidth are three main problems facing multimedia streaming applications over the Internet. Existing techniques such as Media-aware network protocol, network adaptive source and channel coding, etc. have been proposed to either overcome or alleviate these drawbacks of the Internet. But these techniques either need specialized...

Node and topology management for content distribution in source constraint networks

Creator:: Kolazhi, Krishnan
Abstract:: As broadband Internet becomes widely available, Peer-to-Peer (P2P) applications over the Internet are becoming increasingly popular. Such an example is a video multicast application in which, one source streams a video to a large number of destination nodes through an overlay multicast tree consisting of peers. These overlay multicast-based applications,...

Development of Hot-melt Pan-coating, Application to Sustained-release Capsules and Tamper Resistant-coating. 2) Formulation of Verapamil HCl and Diltiazem HCl Semisolid Matrix Capsules. 3) Novel Sustained Release Tablet of Glipizide: Compression of Coated Drug Beads, Formulation, Dissolution, and Convolution. 4) Verapamil Sustained Release: New Formulation and Convolution

Creator:: Nguyen, Chien Ngoc
Abstract:: Hot-melt pan-coating, which is a novel coating method and takes 2-3 hours for 300 mg coating weight gain per capsule and tamper-resistant coating, which takes 30 minutes, is much faster than tedious sugar coating and allows greater coating weight gains in shorter times than spray-melt coating. Although hot-melt pan coating...

Autonomous helicopter systems: design and implementation solutions

Creator:: Nguyen, John
Abstract:: Creating intelligent robotics is at the cutting edge of technology. Unmanned aerial vehicles (UAV) are of particular interest for surveillance applications. UAVs have the potential to provide quick and cheap aerial data that would be difficult to obtain by conventional means. UAVs also have the ability to navigate without being...

Development of benthic habitat maps and GIS (Geographic Information System) modelling to support coastal zone management in Phu Quoc, Vietnam

Creator:: Nguyen, Vinh X.
Abstract:: Situated off the west coast of Vietnam in the Gulf of Thailand, Phu Quoc archipelago and its waters are well-known for their rich natural resources, especially the bounty of fishery resources. Under increasing pressure from the growing population, fishing, and tourism development, there is a strong need to formulate an...

A channelized digital receiver design for UWB sytems in a multipath indoor environment

Creator:: Chang, Yuhao
Abstract:: This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...

Data processing for anomaly detection in web-based applications

Creator:: Gaarudapuram Sriraghavan, Rajagopal
Abstract:: Web applications are popular attack targets. Misuse detection systems use signature databases to detect known attacks. However, it is difficult to keep the database up to date with the rate of discovery of vulnerabilities. They also cannot detect zero-day attacks. By contrast, anomaly detection systems learn the normal behavior of...

Gray codes and their applications

Creator:: Anantha, Madhusudhanan
Abstract:: An n-bit Gray code is an ordered set of all 2n binary strings of length n. The special property of this listing is that Hamming distance between consecutive vectors is exactly 1. If the last and first codeword also have a Hamming distance 1 then the code is said to...

Network coding in relay networks

Creator:: Alban, Eduardo
Abstract:: Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...
