Development and analysis of solar energy based multigeneration systems
(2015-05-01)
In this thesis three novel multigeneration energy systems are introduced based on renewable resources such as solar and wind energy. The results of the analyses show that, System 1 has a maximum energy efficiency of 43% ...
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 ...
Optimal resource sharing and spectrum leasing in energy efficient relay-assisted networks
(2015-07-01)
Assuming a bidirectional relay assisted network, we first study the problem of optimal resource sharing between two transceiver pairs. One of the pairs, referred to as the primary pair, owns the spectral resources while ...
Mechanics of machining metal matrix composites: analytical modeling and finite element simulation
(2015-01-01)
Metal matrix composites (MMCs) are commonly utilized materials in various industries, including applications in aerospace and automotive industries, due to their outstanding strength-to-weight ratio and wear resistance. ...
Robotic radiation mapping using modelling and probabilistic analysis of sparse data
(2015-07-01)
An approach for generating radiation intensity maps, comprised of a mobile robotic platform and an integrated radiation model, is presented, and its ability to generate accurate radiation maps in simulation studies as well ...
Development, optimization and simulation of hybrid electric heavy duty truck with self-propelled trailer.
(2014-11-01)
The hybrid electric drivetrain has significant ability to reduce fuel consumption and
increase the efficiency. The application of this type of drivetrain has been investigated for
different vehicle models. The hybridization ...
Torque control strategy for off-road vehicle mobility.
(2014-11-01)
Multi-wheeled off-road vehicles behavior depend not only on the total provided power by the engine but also on the power distribution among the drive axles/wheels. In turn, this distribution is primarily regulated by the ...
Multiphase flow and chemical reactor thermodynamics for hydrolysis and thermochemical production
(2012-08-01)
Current techniques of hydrogen production (primarily reformation of fossil fuels) are
unsustainable, releasing CO2 into the atmosphere, as well as consuming limited reserves
of fossil fuels. The copper-chlorine cycle is a ...
Ultrasonic array imaging for multi-layer materials in non-destructive testing applications.
(2014-12-01)
Ultrasonic imaging for a multi-layer medium is a common challenge in seismology,
medical diagnosis, and non-destructive testing. One application for multi-layer imaging
is ultrasonic immersion test where the material ...
Design and characterization of next-generation tissue equivalent proportional counters for use in low energy neutron fields
(2014-04-01)
Tissue Equivalent Proportional Counters (TEPCs) are devices that can measure the radiation dose levels for the mixed neutron and gamma ray fields that are encountered in nuclear facilities. TEPC designs typically consist ...
