The physiology and behaviour of ectotherms are strongly influenced by environmental temperature. A general hypothesis is that for performance traits, such as those related to growth, metabolism or locomotion, species face a trade-off between being a thermal specialist or a thermal generalist, implying a negative correlation between peak performance and performance breadth across a range of temp...

Determining organismal responses to climate change is one of biology's greatest challenges. Recent forecasts for future climates emphasize altered temperature variation and precipitation, but most studies of animals have largely focused on forecasting the outcome of changes in mean temperature. Theory suggests that extreme thermal variation and precipitation will influence species performance a...

In this paper we present a technique for fusion of optical and thermal face images based on image pixel fusion approach. Out of several factors, which affect face recognition performance in case of visual images, illumination changes are a significant factor that needs to be addressed. Thermal images are better in handling illumination conditions but not very consistent in capturing texture det...

The use of physiological data from human tests in modelling should consider background data, such as activity, environmental factors and clothing insulation on the whole body. The present paper focuses on local thermal comfort of feet with special attention on the effects of physical changes of footwear thermal properties. An alternative test method is available for footwear thermal testing bes...

simultaneous thermal analysis (sta) method has been applied to study decomposition reactions of ap under a flowing nitrogen atmosphere and static air. results obtained indicate that a phase transformation occurs prior to the decomposition reaction. decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. addition...

This paper illustrates an application of a technique for predicting the thermal characteristics of a bidirectional thermocycling device for polymerase chain reaction (PCR). The micromilling chamber is oscillated by a servo motor and contacted with different isothermal heating blocks to successfully amplify the DNA templates. Because a comprehensive database of contact resistance factors does no...

Conductive asphalt concrete with high thermal conductivity has been proposed to improve the solar energy collection and snow melting efficiencies of asphalt solar collector (ASC). This paper aims to provide some insight into choosing the basic materials for preparation of conductive asphalt concrete, as well as determining the evolution of thermal characteristics affected by environmental facto...

Thermal dose has been identified as one of the most important factors which influence the efficacy of hyperthermia. Adequate temperature must be delivered for an appropriate period of time to the entire tumor volume in order to achieve optimal therapeutic results. Present clinical thermometry systems provide coarse temperature readings, since only selected tumor or normal tissue temperatures ar...

he increasing amount of heat generated by electronic devices is making devices thermal design and ways to combat heat more and more important issues to deal with. Therefore, we have developed a system able to evaluate thermally conductive materials such as conductive adhesives. The measurement technology is based on the steady-state method, and can evaluate heat transfer characteristics of moun...
