Morphology analysis of vertebral trabecular bone under dynamic loading based on multi-scale theory
(Springer-Verlag, 2012-10)Trabecular bone has a complicated porous microstructure and consists of interconnected plates and rods known as trabeculae. The microarchitecture of the trabeculae contributes to load distribution capacity and, particularly, ... -
The use of dielectric mixture equations to analyze the dielectric properties of a mixture of rubber tire dust and rice husks in a microwave absorber
(Progress in Electromagnetics Research (PIER), 2012)A change in the relative proportions of a mixture of rubber tire dust and rice husks will cause a change in the mixture's electrical permittivity and its ability to absorb electromagnetic energy. An openended coaxial probe ... -
Effectiveness–NTU correlation for low temperature PCM encapsulated in spheres
(Elsevier Ltd., 2012-05)The applicability of the effectiveness–NTU method for characterising a PCM thermal energy storage system was experimentally investigated. The system consisted of PCM encapsulated in spheres with a liquid heat transfer ... -
Hypovigilance detection using energy of electrocardiogram signals
(NISCAIR PUBLICATIONS, 2012-12)Driver drowsiness and driver inattention are the major causes for road accidents leading to severe traumas such as physical injuries, deaths, and economic losses. This necessitates the need for a system that can alert the ... -
Optimising PCM thermal storage systems for maximum energy storage effectiveness
(Elsevier Ltd., 2012-09)A new performance parameter for PCM thermal storage systems, the energy storage effectiveness, is defined. This parameter can be used to optimise the design of any PCM thermal storage system to maximise the use of the ... -
