Uncertainties such as measurement noise are unavoidable in inverse problems and often lead to unstable solutions due to the ill-posed nature of such problems. However, there is a rich statistical information contained in the actual data that is often not used. In this paper, we explore the solution of stochastic inverse heat conduction problems where the unknowns (e.g. boundary heat flux or dis...

A new method for measuring the heating rate (defined as the time rate of change of temperature) and estimating heat flux from the heating rate is proposed. The example problem involves analytic heat conduction in a one-dimensional slab, where the measurement location of temperature or heating rate coincides with the location of the estimated heat flux. The new method involves the solution to a ...

The heat produced when an animal is fasted in an environment which is neither too hot nor too cold to cause increases in metabolism is a measure of the energy needed to maintain that animal. When man is the subject, muscular repose can invariably be assured and the measurement of heat production is termed the basal metabolism. Most animals do not co-operate in the way that man does and their he...

Analysis of multiple analytes from biological samples can be challenging as different analytes require different preservation measures. Heat induced enzymatic inactivation is an efficient way to preserve proteins and their modifications in biological samples but RNA quality, as measured by RIN value, has been a concern in such samples. Here, we investigate the effect of heat stabilization compa...

Heat exchangers are some of the most important parts in thermoacoustic devices. In an oscillatory flow condition, the flow and temperature fields around the heat exchangers can be quite complex and it may significantly affect their heat transfer behaviour. As a result, one cannot directly apply the heat transfer correlations for a steady flow to the design of heat exchangers operating in oscill...

ABSTRACT State estimation procedures using the extended Kalman filter are investigated for a transient heat transfer problem in which a heat source is applied on one side of a thin plate and ultrasonic time of flight or temperature is measured on the other side of the plate. A forward conduction solution is developed using finite element methods and verified using closed-form analytic solutions...

Global warming will unquestionably increase the impact of heat on individuals who work in already hot workplaces in hot climate areas. The increasing prevalence of this environmental health risk requires the improvement of assessment methods linked to meteorological data. Such new methods will help to reveal the size of the problem and design appropriate interventions at individual, workplace a...
