Single-stage boost integrated asymmetrical half-bridge AC-DC power converter with dual modulation for indoor led lighting
(2015-04-01)
Light emitting diodes (LEDs) for indoor lighting is a promising technology which can lead to major energy saving and cost reductions. The major concerns of improving power factor and regulating the output current ripple ...
Design and development of an automated pellet inspection system for nuclear fuel pellets
(2015-04-01)
A prototype for inline, non-destructive inspection of uranium dioxide (UO2) fuel pellets
at production speeds of two pellets per second is presented. The system tests
the surface of each cylindrical ceramic pellet using ...
Experimental investigation of scroll based organic Rankine systems
(2011-04-01)
In this thesis, an experimental research is conducted on scroll-based Organic Rankine Cycle (ORC) focusing on the expansion process. An important feature of the ORC is the ability to utilize low or moderate temperature ...
Novel opposition-based sampling methods for efficiently solving challenging optimization problems
(2011-04-01)
In solving noise-free and noisy optimization problems, candidate initialization and sampling
play a key role, but are not deeply investigated. It is of interest to know if the entire
search space has the same quality for ...
Model predictive control of wheeled mobile robots
(2010-12-01)
The control of nonholonomic wheeled mobile robots (WMRs) has gained a lot of attention
in the field of robotics over the past few decades as WMRs provide an increased range of
motion resulting in a larger workspace. This ...
Test platform design and control of a bicycle-type two-wheeled autonomous vehicle
(2011-03-01)
Bicycle dynamics and behaviors have been vastly studied through modeling and
simulation. Due to the complexity, software models are often assumed subjecting
to di erent nonholonomic constraints in order to simplify the ...
Motion planning for multi-link robots with artificial potential fields and modified simulated annealing
(2010-12-01)
In this thesis we present a hybrid control methodology using Artificial Potential Fields (APF) integrated with a modified Simulated Annealing (SA) optimization algorithm for motion planning of a multi-link robots team. The ...
Analysis and processing issues of plastic color mismatch
(2011-05-01)
Color is a visual characteristic which imparts the ability to categorize different
objects. When light strikes an object, there are three possibilities as to what can happen.
The light may be reflected, refracted or ...
Secure and compromise-resilient architecture for advanced metering infrastructure
(2011-03-01)
In recent years, the Smart Grid has grown to be the solution for future electrical energy that promises to avoid blackouts as well as to be energy efficient, environmentally and customer-friendly. In Smart Grid, the ...
Optimal power minimization in two-way relay network with imperfect channel state information
(2010-08-01)
We study a two-way amplify and forward relay network with two transceivers which
communicate through a network of nr relays while there is no direct link between the two
transceivers. Each relay is equipped with a single ...
