Video over Cognitive Radio Networks: A Cross-Layer Optimization Approach
(2012-05-01)
Cognitive radios (CR) are intelligent radio devices that can sense the radio environment and adapt to changes in the radio environment. CR represents a new paradigm of wireless communications and networking by efficiently ...
Controlled Transition Density Based Power Constrained Scan-BIST with Reduced Test Time
(2012-03-08)
Controlling power dissipation in large circuits during test sessions is one of the major concerns in VLSI testing. The reason behind the high power dissipation during test is because unlike normal mode operation of the ...
Surface Flashover Studies of Dielectric Polymer Nanocomposites under KHz Unipolar Pulsed Fields in Partial Vacuum Environment
(2012-03-21)
Insulating materials play a significant role in high voltage power systems. In general, the high performance electrical insulation materials and structures must be free from unwanted and unpredictable dielectric breakdown ...
Design of 3.33GHz CML Processor Datapath
(2012-04-17)
Almost a decade processor speed has been stuck at operating frequency 2-3GHz due to excessive power consumption of CMOS logic gate at higher frequency whereas predicted speed at present was 10-15GHz. This leads the idea ...
UAV Collision Avoidance using A* Algorithm
(2012-04-13)
Collision avoidance is the essential requirement for unmanned aerial vehicles (UAVs) to become fully autonomous. Several algorithms have been proposed to do the path planning in a simulated environment, but only few can ...
Non-collocated Control of an Autonomous Robot-Trailer System Using State Estimation
(2012-04-09)
In this work, the author develops an observer and non-collocated controller for a robot-trailer system in which only the position of the trailer is measured. A linearized state-space model of the system is derived using ...
RLCH: Reliable Link lifetime based Cluster Head election in MANET
(2012-07-16)
Clustering has been widely considered in wireless ad hoc networks as a useful mechanism for solving the scalability problems, improving the stability, increasing the network’s energy efficiency, etc. The idea behind ...
Resource Allocation and Precoding in Cognitive Radio and Relay Networks
(2012-11-16)
In this dissertation, two promising technologies which improve the spectrum efficiency
in wireless networks are investigated: cognitive radio (CR) and relay technology. Cognitive
radio, as a promising technology to ...
Low Noise, Low Power Capacitive-Coupling Quadrature Voltage-Controlled Oscillator for Phase-Locked Loops
(2012-11-06)
This dissertation presents the analytical results and design details of two quadrature voltage-controlled oscillators (QVCO). It uses capacitive quadrature-coupling technique to couple two voltage-controlled oscillator ...
Biventricular Active Mesh Model of the Heart and Analysis of Morphologic Changes Toward Physiology and Pathologies
(2012-08-15)
Cardiovascular disease (CVD) has been reported as the number one cause of death in the world. It is estimated that by 2030, about 23.6 million people will die from a type of CVD. It is a problem that crosses both gender ...
