Diffusion in inhomogenous media
(2009-10-30)This project considers the diffusion of water molecules through a cellular medium in which the cells are modeled by square compartments placed symmetrically in a square domain. We assume the diffusion process is governed ... -
Joint uplink-downlink beamforming in multi-antenna relaying schemes
(2009-11-01)The thesis examines the problem of joint receive and transmit beamforming for a wireless network which consists of one relay node equipped with multiple antennas. The transmitter and the receiver are single antenna ... -
Decentralized state-space controller design of a large PHWR
(2009-11-01)The behaviour of a large nuclear reactor can be described with sufficient accuracy using a nodal model, like the spatial model of a 540 MWe large Pressurized Heavy Water Reactor (PHWR). This model divides the reactor into ... -
Dynamic flowgraph methodology for reliability modelling of networked control systems: with application to a nuclear-based hydrogen production plant
(2009-12-01)The use of communication networks in digital control systems introduces stability and reliability concerns. Standard reliability and safety assessment methods need further modification to accommodate the issue in the ... -
Transient heat transfer analysis of heat exchangers in a Marnoch Heat Engine

Development of a heat-transfer correlation for supercritical water in supercritical water-cooled reactor applications
(2009-12-01)A large set of experimental data, obtained in Russia, was analyzed and a new heat-transfer correlation for supercritical water was developed. This experimental dataset was obtained within conditions similar to those for ... -
On the integration of Computational Fluid Dynamics (CFD) simulations with Monte Carlo (MC) radiation transport analysis
(2009-12-01)Numerous scenarios exist whereby radioactive particulates are transported between spatially separated points of interest. An example of this phenomenon is, in the aftermath of a Radiological Dispersal Device (RDD) ... -
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 ... -
Stability of heroin metabolites and oxycodone in rat hair and liver during decomposition
(2010-01-01)The aim of this study was to investigate the influence of soft tissue decomposition on the stability of drugs incorporated in hair antemortem. Two burial trials were conducted: in the first trial, rats were administered ... -
Reliability evaluation of the two bus interface controllers in the Darlington simulator
(2010-01-01)The Darlington simulator is now two decades old and, in common with any nuclear simulator of a similar age, suffers the problem of parts aging and obsolescence. In the past, replacement parts were available from the original ... -
The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
(2010-04-01)Tissue equivalent proportional counters (TEPCs) are commonly used for radiation monitoring in areas where a mixture of neutron and photon radiations may be present, such as those commonly encountered in nuclear power plants. ... -
