Risk-informed maintenance for non-coherent systems
(2010-12-01)
Probabilistic Safety Assessment (PSA) is a systematic and comprehensive methodology to evaluate risks associated with a complex engineered technological entity. The information provided by PSA has been increasingly implemented ...
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 ...
Integration of component-based frameworks with sensor modeling languages for the sensor web
(2010-08-01)
The goal of this thesis is to develop an easily modifiable sensor system. To achieve this goal SensorML (an XML based sensor language) is combined with Java Beans (a component model language). An important part of SensorML ...
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 ...
Piezoelectric flexing and output voltage of a microchannel heat engine
(2010-08-01)
In this thesis, a new model is formulated for a piezoelectric membrane and fluid motion in a microchannel heat engine. A new slug flow model is developed for droplet motion in a circular cross-section channel. The model ...
Optomal three-time slot distributed beamforming for two-way relaying
(2010-08-01)
In this study, we consider a relay network, with two transceivers and r relay nodes. We
assume that each of relays and the two transceivers have a single antenna. For establishing
the connection between these two transceivers, ...
A Hybrid LCC-VSC HVDC Transmission System Supplying a Passive Load
(2010-12-01)
High Voltage Direct Current (HVDC) transmission systems continue to be an excellent
asset in modern power systems, mainly for their ability to overcome the problems of AC
transmission, such as the interconnection of ...
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 ...
Powertrain technology and cost assessment of battery electric vehicles
(2010-04-01)
This thesis takes EV from the late 90’s as a baseline, assess the capability of today’s EV technology, and establishes its near-term and long-term prospects. Simulations are performed to evaluate EVs with different ...
Cooperative localization based on received signal strength in wireless sensor network
(2010-01-01)
Localization accuracy based on RSS (Received Signal Strength) is notoriously inaccurate
in the application of wireless sensor networks. RSS is subject to shadowing effects, which is signal attenuation caused by stationary ...
