Experimental study of applying grooves on semi-tubular blank sheet metal using incremental sheet forming.
(2013-08-01)
Incremental sheet forming (ISF) was a flexible sheet metal forming process which utilized a variety of forming tools, materials, and dies. ISF was implemented to develop a series of column covers which visually replicated ...
Time-frequency analysis techniques for non-intrusive load monitoring
(2016-10-01)
The work
in this thesis examines time-frequency analysis techniques and in particular the wavelet
transform to extract the features contained within the electrical load signals. A novel approach
that is based on wavelet ...
User-centric analytics for expert crowds
(2015-09-01)
Pervasiveness and permissiveness of social media made content verification an integral part of any analysis involving online generated data. The most natural and convenient way to assess content trustworthiness and validity ...
Design and Optimization of Intelligent PI Controllers (Fuzzy and Neuro-Fuzzy) for HVDC Transmission System
(2010-08-01)
This thesis deals with enhancing the performance of Fuzzy Logic (FL) based PI controllers for High Voltage Direct Current Transmission Systems (HVDC) by optimizing the key parameters i.e. membership functions (MFs) and ...
Simulation of voltage source converter based shunt active filter in EMTP‐RV
(2010-08-01)
The deterioration in power quality due to the increase in non linear loads has sparked a new interest
in the filtering techniques used in transmission and distribution systems. Unlike passive filters, active
filters are ...
Achieving high efficiency thermoelectric heating and cooling with metal foam heat exchangers
(2014-04-01)
This thesis examines the development of a high efficiency heat pump system using
thermoelectric (TE) and reticulated metal foam (RMF) technologies to power a vehicle`s
battery thermal management system. The focus is split ...
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 ...
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 ...
