Detecting sources of heat loss in residential buildings from infrared imaging
… was conducted to determine the most common sources of heat loss during the winter in residential buildings. 135 houses in the greater Boston and Cambridge area were photographed, stitched, and tallied to characterize nine major causes of heat loss: window frames, window surfaces, window …

Modeling Arthropod Traits in a Bayesian Framework
… body temperature, they are dependent on external sources of heat. Because of this, temperature has a large influence on many of their physiological traits that affect fitness, such as development time or lifespan, which in turn, alters their ability to transmit disease-causing pathogens. The …

Implications of the Dense City Centre to Surface-Atmosphere Exchanges
… entangled with human activities. This study of the central business district (CBD) analyses an extended (3.5 years) dataset of surface-atmosphere energy exchanges in London. The focus is on the controls on radiation, anthropogenic heat and the turbulent latent and sensible heat fluxes. The …

Sodium chlorate oxygen generation for fuel cell power systems
… thesis we experimentally investigated the use of sodium chlorate as an oxygen storage medium for use in underwater fuel cell power systems. Research into improving hydrogen storage systems is the primary concern when designing fuel cell systems with access to atmospheric oxygen. However, in an …

Analysis of a space experimental design for high-Tc superconductive thermal bridges
… bridges and, consequently, the mission lifetimes of the satellites are limited due to cryogenic evaporation. High-temperature superconductor (HTS) materials have been proposed by researchers at the National Aeronautics and Space Administration Langley's Research Center (NASA-LaRC) as an …

Experimental design, analysis and improvement of a Marnoch Heat Engine with heat recovery.
This research examines the prototyping of a Marnoch Heat Engine (MHE) and conducts thermodynamic and heat transfer analyses of this heat engine with a waste heat recovery system. The heat source for the MHE can be low grade heat (about 365 K). During cold seasons an ambient temperature can be …

A Dynamic Model Of The Human/cooling System/clothing/environment System
… body compensates well for moderate climatic heat stress, but artificial environments often block or overwhelm physiological defense mechanism. Personal protective equipment (PPE) is one of sources of heat stress. It protects individual from chemical, physical, or biological hazards, but the …

Projected sea level rise and the conservation ecology of the Micronesian Megapode (Megapodius laperouse senex) in Palau, Micronesia
Climate change has been a subject of numerous studies. While findings suggest that most biological taxa will be affected by its manifestations, aspects of a species life history may increase its susceptibility to climate change. Given their reliance on environmental sources of heat to incubate …

Malleefowl and anthropogenic change: an integrated analysis of population trends, landscape genetics and movement ecology
… mounds to incubate their eggs using external sources of heat. Malleefowl numbers have drastically decreased since European settlement and they are now a nationally threatened species. Their decline is caused by habitat loss and fragmentation; predation by introduced species; inappropriate fire …
