There is urgent need to monitor dental and oral diseases, such as tooth decay, gum diseases, and teeth grinding. Such monitoring can be achieved by embedding sensors in the mouth. This technique faces some difficulties. The first is how the power needed for the operation of the sensors and the associated electronic chips can be generated. This power can be generated using the pressure exerted by ...

Simulation models for steady state thermal hydraulics analyses of ORNL’s HFIR have been developed using COMSOL. A single fuel plate and coolant channel of each type of HFIR fuel element was modeled in three dimensions. The standard k-? turbulence model was used in simulating turbulent flow with conjugate heat transfer. The COMSOL models were developed to be fully parameterized to allow ...

Green house gases emission associated with natural hazard of underground coal seam fire has been recognized as a worldwide problem leading to global warming threat. Therefore, in this paper a model to study underground coal fire is presented and the results will be devoted to strategic development of coal fire extinction technology within the framework of Sino-German Coal Fire Research ...

Pressure sensors operating at the temperature higher that 500 °C are absent in the world market. Our goal is to develop a pressure sensor that can operate at the high temperature up to 700 °C. Our sensor will be made up of a ceramic sensible element and a metallic case. The sensible element will be a ceramic beam with a Weathstone bridge on its surface. A structural analysis on the case has been ...

The majority of elderly patients are subjected to hip bone replacement due to dislocation of bone, mechanical failure and infection. The life time of the implant varies from patient to patient depending on their daily physical activity. Once the implant fails, re-operation of hip bone replacement is performed. In United States, there are approximately 18 revision hip replacements performed for ...

Simulation of criticality accident transients offers the ability to confirm understanding of critical configurations, bound accident scenarios and aid comprehensive emergency planning. Computational ability to recreate excursion power histories in fissile solution is sought due to the predominance of solutions in process criticality accidents. Applicable solution transient physics methodologies ...

Two finite element models have been developed to investigate the acoustic radiation from a Pratt truss train bridge. The first model was a time dependent structural model that determined the vibration response of the structure due to two wheels, representing a single axle, moving across the bridge at constant speed. This model was expanded to include multiple axles to represent a locomotive. The ...

Introduction: The sectoral plan that defines the procedure and criteria of site selection for deep geological repositories for all categories of waste (high-level and low- and intermediate-level waste) in Switzerland started in 2008 and will last for about ten years. ENSI (Swiss Nuclear Safety Inspectorate) is in charge of reviewing the proposals and safety assessments for geological ...
