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 ...
Radiated Emissions Extrapolation Issues
(2010-03-24)
In this thesis, the complicated problem of extrapolating radiated emissions from one range to another is tackled. A model employing a Method of Moments (MoM) formulation is presented to compare alongside measurements which ...
Handover Management in Femtocell Networks
(2014-04-25)
Radio communication has come a long way from 1G Advanced Mobile Phone Systems
(Amps) voice to Evolved 3G Enhanced Voice Data Optimized (EVDO), High Speed Packet
Access plus (HSPA+) and 4G Long Term Evolution (LTE) now. ...
Finding Optimum Clock Frequencies for Aperiodic Test
(2014-04-29)
With scale down in technology, size and complexity of integrated circuits increase. The
scan method is the most popular technique of testing sequential circuits today. In this
method,
ip-
ops functionally form one or ...
Multi-Robot Frontier Based Map Coverage Using the ROS Environment
(2014-04-25)
Cooperative robotics deals with multiple robot platforms working to accomplish a common
goal and has a multitude of applications including security, surveying, search and rescue,
and many more. The use of multiple robots ...
