A temporal topic model for social trend prediction
(2017-08-01)
Social media provides increasing opportunities for users to voluntarily share their thoughts and concerns in a large volume of data. While user-generated data from each individual may not provide considerable information, ...
Design, analysis and experimental investigation of Cu-Cl based integrated systems
(2013-01-01)
Burning fossil fuels for power generation results in emissions of greenhouse gases such as carbon dioxide (CO2) and air pollutants such as nitrogen oxides (NOx) and sulfur oxides (SOx), which are harmful to living creatures ...
A framework of image processing for image-guided procedures
(2016-07-01)
Contrary to the cases of open surgery, during minimally invasive procedures,
surgeons have no direct access or very limited access to the operative site and
can only visualize the site and the focal region with the aid of ...
Sparse signal representation based algorithms with application to ultrasonic array imaging
(2016-06-01)
We address one- and two-layer ultrasonic array imaging. We use an array of transducers to inspect the internal structure of a given specimen. In the case of one-layer imaging we also address the problem of mode conversion. ...
Leadership based multi-objective optimization with applications in energy systems.
(2013-12-01)
Multi-objective optimization metaheuristics (MOMs) are powerful methods for solving complex optimization problems but can require a large number of function evaluations to find optimal solutions. Thus, an efficient ...
Experimental and theoretical investigations of magnesium-chlorine cycle and its integrated systems
(2015-01-01)
This study aims to investigate the feasibility of the Mg-Cl hybrid thermochemical cycle and to develop a more cost and energy effective cycle. There are five key elements of this study: (i) modeling and simulation of the ...
Modeling, analysis and optimization of integrated energy systems for multigeneration purposes
(2013-08-01)
Energy use is directly linked to well-being and prosperity across the world. Meeting the growing demand for energy in a safe and environmentally responsible manner is an important challenge. There are around seven billion ...
Intelligent fault diagnosis of gearboxes and its applications on wind turbines
(2013-02-01)
The development of condition monitoring and fault diagnosis systems for wind turbines has received considerable attention in recent years. With wind playing an increasing part in Canada’s electricity demand from renewable ...
Investigation of factors that influence coloration in polycarbonate based compounded plastics
(2015-08-01)
Consistently producing compounded plastics in the correct colour without making
adjustments of the colour formulation or the processing conditions is very challenging for
coloured plastics manufacturers. Conversely, the ...
User behavior pattern based security provisioning for distributed systems
(2016-01-01)
Behaviors of authorized users must be monitored and controlled due to the rise
of insider threats. Security analysts in large distributed systems are overwhelmed
by the number of system users, the complexity and changing ...
