Low Correlation Sequences Over AM-PSK And QAM Constellations
(2009-08-13)
Direct-Sequence Code Division Multiple Access (DS-CDMA), over the last few years, has become a popular technique and finds a place in many modern communication systems. The performance of this technique is closely linked ...
Robust Techniques Of Language Modeling For Spoken Language Identification
(2009-07-23)
Language Identification (LID) is the task of automatically identifying the language of speech signal uttered by an unknown speaker. An N language LID task is to classify an input speech utterance, spoken by an unknown ...
Energy Efficient Scheduling Of Sensing Activity In Wireless Sensor Networks Using Information Coverage
(2009-08-19)
Network lifetime is a key issue in wireless sensor networks where sensor nodes, distributed typically in remote/hostile sensing areas, are powered by finite energy batteries which are not easily replaced/recharged. Depletion ...
Cooperative Communication Protocols : Diversity-Multiplexing Gain Tradeoff And Code Constructions
(2009-05-19)
Cooperative relay communication is a promising means of wireless communication in which cooperation is used to create a virtual transmit array between the source and the destination, thereby providing spatial diversity for ...
Procurement Network Formation : A Cooperative Game Theoretic Approach
(2009-04-16)
Complex economic activity often involves inter-relationships at several levels of production, often referred to as supply chains or procurement networks. In this thesis we address the problem of forming procurement networks ...
Efficient Online Path Profiling
(2009-06-05)
Most dynamic program analysis techniques such as profile-driven compiler optimizations, software testing and runtime property checking infer program properties by profiling one or more executions of a program. Unfortunately, ...
Caching Techniques For Dynamic Web Servers
(2009-03-20)
Websites are shifting from static model to dynamic model, in order to deliver their users with dynamic, interactive, and personalized experiences. However, dynamic content generation comes at a cost – each request ...
Discovering Roles In The Evolution Of Collaboration Networks
(2009-04-02)
Searching the Web involves more than sifting through a huge graph of pages and hyperlinks. Specific collaboration networks have emerged that serve domain-specific queries better by exploiting the principles and patterns ...
A Mechanism Design Approach To Resource Procurement In Computational Grids With Rational Resource Providers
(2009-07-08)
A computational grid is a hardware and software infrastructure that provides dependable, consistent, pervasive, and inexpensive access to high-end computational capabilities. In the presence of grid users who are autonomous, ...
Spill Code Minimization And Buffer And Code Size Aware Instruction Scheduling Techniques
(2009-05-19)
Instruction scheduling and Software pipelining are important compilation techniques which reorder instructions in a program to exploit instruction level parallelism. They are essential for enhancing instruction level ...
