DYNAMICS OF RANDOM EARLY DETECTION GATEWAY UNDER A LARGE NUMBER OF TCP FLOWS
(2004-03-11)
While active queue management (AQM) mechanisms such as Random Early Detection (RED) are widely deployed in the Internet, they are rarely utilized or otherwise poorly configured. The problem stems from a lack of a tractable ...
Network flow optimization and distributed control algorithms
(2006-11-21)
This thesis concerns the problem of designing distributed algorithms for achieving efficient and fair bandwidth allocations in a resource constrained network. This problem is fundamental to the design of transmission ...
The study and development of automatic data acquisition system for spin-stand imaging and drive independent recovery of hard disk data
(2007-04-25)
In this thesis, an automatic data acquisition system for spin-stand imaging and drive independent data recovery is developed. This system enables a user to perform data acquisition of on-track hard disk data by using a ...
Beamforming Algorithms for Information Relaying in Dense Wireless Networks
(2006-04-19)
In this dissertation we develop a class of bandwidth-efficient algorithms for information relaying in large-scale wireless ad-hoc networks. The settings we consider involve a single source communicating its data to a ...
Low Power Smartdust Receiver with Novel Applications and Improvements of an RF Power Harvesting Circuit
(2009)
Smartdust is the evolution of wireless sensor networks to cubic centimeter dimensions or less. Smartdust systems have advantages in cost, flexibility, and rapid deployment that make them ideal for many military, medical, ...
Hearing VS. Listening: Attention Changes the Neural Representations of Auditory Percepts
(2008-05-01)
Making sense of acoustic environments is a challenging task. At any moment, the signals from distinct auditory sources arrive in the ear simultaneously, forming an acoustic mixture. The brain must represent distinct auditory ...
Exploiting Soft Computing for Real time performance
(2006-08-15)
The classic approach to the design of real time systems is to determine worst-case scenarios for the system statically and manually and then build the system with sufficient resources to meet deadlines and goals. This ...
Jointly Optimal Placement and Power Allocation of Wireless Networks
(2008-04-28)
In this thesis, we investigate the optimal design of wireless networks. We consider wireless networks that have fixed and movable nodes, and we assume that all nodes feature adjustable transmission power. Hence, we aim at ...
High-Performance 3D Image Processing Architectures for Image-Guided Interventions
(2008-04-21)
Minimally invasive image-guided interventions (IGIs) are time and cost efficient, minimize unintended damage to healthy tissues, and lead to faster patient recovery. Advanced three-dimensional (3D) image processing is a ...
Fabrication of Bragg Gratings Using Interferometric Lithography
(2007-04-30)
A setup has been designed and realized for the fabrication of Bragg Gratings in edge emitting semiconductor laser. In this setup a HeCd laser, at 325nm, is used in a Lloyd's mirror configuration, to interferometrically ...
