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. ...
Analysis, assessment and optimization of integrated solar energy systems for multigeneration
(2014-12-01)
The extensive usage of fossil fuel in most of human activities has led to the undesirable effects on the environment starting from global warming and greenhouse effects to the climate changes, acid rain and others. Renewable ...
Colour mismatch in compounding of plastics: processing issues and rheological effects
(2015-01-01)
Demand for plastic products is continuously growing with population increase and higher living standards. Imparting colours to plastics is a combination of art and science and plays a key role in production of attractive ...
Thermal sustainability of low-temperature geothermal energy systems: System interactions and environmental impacts.
(2013-10-01)
In storing heat during summer for use in winter, the ground provides a better source/sink
of heat than the outside air in regards to heat pump efficiency, being cooler than the outside air in the summer and warmer in the ...
Advances in parallel robotics for flexible and reconfigurable manufacturing
(2014-04-01)
Parallel robotic manipulators are a specific type of robot that has multiple
limbs which are ultimately connected to a moving body. Within
this regime, there are several sub-classes of robots characterized by
certain ...
An advanced electrospinning method of fabricating nanofibrous patterned architectures with controlled deposition and desired alignment
(2015-11-18)
We introduce a versatile advanced method of electrospinning for fabricating various kinds of nanofibrous patterns along with desired alignment, controlled amount of deposition and locally variable density into the ...
Experimental and theoretical investigation of novel phase change materials for thermal applications
(2015-08-01)
An experimental investigation is conducted to test the thermal properties, behaviour and characteristics of R134a clathrates with additives, as phase change materials (PCMs). PCMs’ charging characteristics are analysed and ...
Asynchronous bi-directional relay-assisted communication networks
(2014-02-01)
We consider an asynchronous bi-directional relay network, consisting of two singleantenna
transceivers and multiple single-antenna relays, where the transceiver-relay
paths are subject to different relaying and/or ...
Mass transfer and particle dissolution in liquid-gas and solid-liquid flows: Application to hydrogen production processes.
(2013-10-01)
Many environmental problems are related to the production, transformation and use
of energy. Some of the concerns include, but are not limited to, acid rain, ozone depletion
and climate change. Therefore, “greener” ...
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 ...
