Boxicity, Cubicity And Vertex Cover
(2010-09-28)The boxicity of a graph G, denoted as box(G), is the minimum dimension d for which each vertex of G can be mapped to a d-dimensional axis-parallel box in Rd such that two boxes intersect if and only if the corresponding ... -
Comparative Evaluation Of Space Vector Based Pulse Width Modulation Techniques In Terms Of Harmonic Distortion And Switching Loss
(2010-09-14)Voltage source inverters (VSI) are popular in variable speed induction motor drive applications. Pulse width modulation (PWM) is employed to achieve variable voltage variable frequency output from a fixed DC bus voltage. ... -
Compiler Assisted Energy Management For Sensor Network Nodes
(2010-08-16)Emerging low power, embedded, wireless sensor devices are useful for wide range of applications, yet have very limited processing storage and especially energy resources. Sensor networks have a wide variety of applications ... -
Compiler-Assisted Energy Optimization For Clustered VLIW Processors
(2010-04-13)Clustered architecture processors are preferred for embedded systems because centralized register file architectures scale poorly in terms of clock rate, chip area, and power consumption. Although clustering helps by ... -

Diversity-Multiplexing Gain Tradeoff Of Cooperative Multi-hop Networks
(2010-08-23)We consider single-source single-sink (ss-ss) multi-hop relay networks, with slow-fading links and single-antenna half-duplex relay nodes. While two-hop cooperative relay networks have been studied in great detail in terms ... -
Diversity-Mutiplexing Tradeoff Of Asynchronous Cooperative Relay Networks And Diversity Embedded Coding Schemes
(2010-08-23)This thesis consists of two parts addressing two different problems in fading channels. The first part deals with asynchronous cooperative relay communication. The assumption of nodes in a cooperative communication relay ... -
Efficient Frequent Closed Itemset Algorithms With Applications To Stream Mining And Classification
(2010-08-24)Data mining is an area to find valid, novel, potentially useful, and ultimately understandable abstractions in a data. Frequent itemset mining is one of the important data mining approaches to find those abstractions in ... -
Experiential Sampling For Object Detection In Video
(2010-08-26)The problem of object detection deals with determining whether an instance of a given class of object is present or not. There are robust, supervised learning based algorithms available for object detection in an image. ... -
Explicit Segmentation Of Speech For Indian Languages
(2010-07-02)Speech segmentation is the process of identifying the boundaries between words, syllables or phones in the recorded waveforms of spoken natural languages. The lowest level of speech segmentation is the breakup and ... -
