Development and characterization of a high resolution portable gamma spectrometer
(2012-04-01)
The recent disaster of Fukushima in Japan combined with the high demand to enhance nuclear safety and to minimize personal exposure to radioactive materials has a significant impact on research and development of radiation ...
Teachers' views of their technology-focused preservice education program
(2012-04-01)
This study explores the effectiveness of a technology-focused preservice education program by interviewing practicing teachers who have graduated from the program. The views of the teachers are examined with reference to ...
Assessment of FLUENT CFD code as an analysis tool for SCW applications
(2012-08-01)
Chosen as one of six Generation‒IV nuclear-reactor concepts, SuperCritical Water-cooled Reactors (SCWRs) are expected to have high thermal efficiencies within the range of 45 ‒ 50% owing to the reactor‟s high pressures and ...
The application of experimental microdosimetry to mixed-field neutron-gamma dosimetry
(2012-12-01)
Absorbed dose distributions in lineal energy for neutrons and gamma rays were measured by using both a tissue-equivalent walled counter (TEPC) and a graphite-walled low pressure proportional counter (GPC) in the Am-Be ...
The motivational effects of using mobile devices in mathematics classrooms by students with exceptionalities
(2012-04-01)
Low motivation levels experienced by students with exceptionalities in the area of mathematics are often cited as a major factor negatively affecting their potential for success (Baird & Scott, 2009; Reichrath, de Witte, ...
Interactive visualization of the collaborative research network
(2012-01-01)
Social networks have been evolving over the past few years, leading to a rapid increase in the number and complexity of relationships among their entities. In this research, we focus on a large scale dataset known as the ...
OLSR-based network discovery in situational awareness system for tactical MANETs
(2012-01-01)
In this thesis, we propose a high level design for connectivity visualization of OLSRbased
MANET topology based on local topology databases available in an OLSR node.
Two different scenarios are considered: a central ...
Islanding detection in distribution system embedded with renewable-based distributed generation
(2012-12-01)
Classical view of power system is characterized by a unidirectional power flow from
centralized generation to consumers. Power system deregulation gave impetus to a
modern view by introducing distributed generations (DGs) ...
Conceptual design of a thermal hydraulic loop for multiple test geometries at supercritical conditions named supercritical phenomena experimental test apparatus (SPETA)
(2012-04-01)
The efficiency of nuclear reactors can be improved by increasing the operating pressure of current nuclear reactors. Current CANDU-type nuclear reactors use heavy water as coolant at an outlet pressure of up to 11.5 MPa. ...
Simulation, design and construction of a gas electron multiplier for particle tracking
(2012-12-01)
The biological effects of charged particles is of interest in particle therapy, radiation protection and space radiation science and known to be dependent on both absorbed dose and radiation quality or LET. Microdosimetry ...
