Assessing Mesoscale-Equivalent Temperature in Kentucky
… of this research is to investigate mesoscale-equivalent temperatures (TE) in Kentucky and potential land cover influences. Kentucky presents a unique opportunity to perform a study of this kind because of the observational infrastructure provided by the Kentucky Mesonet (www.kymesonet.org). …

Alternative metrics for measuring heating trends, with possible connections between the surface and troposphere
… has been used to describe the observed surface temperature increases during the last century. The proper use of this term, however, requires using surface heat content to monitor this aspect of the climate system. Surface observation site microclimates highlight the influence of land surface …

Efeitos térmicos em estruturas maciças de concreto
… dams, caused, mainly, by high increases of temperature and following gradual cooling, during the inicial phasis of hardening of concrete, dued the quantity of heat generated by the reactions of cement hidration. The temperature distribution is evaluated by transient linear analysis of heat …

Annealing studies of detector materials for uncooled thermal imaging
… thermal detectors which respond to changes in temperature resulting from absorption of infrared radiation, generally in the 8-14µm waveband. In the UK these have been principally based on the pyroelectric effect in ferroelectric materials which have been incorporated into hybrid detectors where …

Gated multi-cycle integration (GMCI) for focal plane array (FPA) applications
… the sensitivity of the detection and the noise equivalent temperature are greatly improved. For a storage well of 106 electrons, the sensitivity of the FPA operated at PSI mode could be improved by 3 orders. In addition, the transmission windows of PSI peak at odd harmonics of the modulation …

Thermal stability of nano-structured selective emitters for thermophotovoltaic systems
… of materials and devices at high operational temperatures. This study focuses on the thermal stability of tungsten selective emitters for thermophotovoltaic (TPV) systems which are anticipated to enhance the conversion efficiency. Selective emitters, 2-D photonic crystals, are periodic …

Workflow design for the analysis of transitional space microclimates application to the analysis of strategies for the improvement of the energy performance and comfort of courtyard buildings in the mediterranean climate
… shading devices had the largest influence on air temperature (monitored up to 13ºC of thermal delta). Albedo, in contrast, had less effect on the air temperature (around 0.2ºC of thermal delta) but had an important influence on user comfort (lowering up to 5ºC in Psychological Equivalent …

Controlling solar radiation through urban form manipulation to improve thermal performance of outdoor spaces in Upper Egypt
… in their building heights) on Physiological Equivalent Temperature (PET) at pedestrian level. This aims to assess possible densification scenarios for the existing part of New Aswan. The results show that the densification has lowered average PET values by 1 °C throughout the entire quarter …

Mitigating urban heat island effects : An analysis of precinct ventilation performance and its impact on urban heat islands and outdoor thermal comfort
… effects. Wind is a critical factor for urban temperature regulation. However, the potential of utilising natural wind for UHI mitigation is significantly constrained by the limited knowledge on urban ventilation at the precinct scale. Many existing studies have focused on the building, city …

Graphene Based Chemical and IR Sensors and Correlated Carrier Transport
… particular gas. Measurements conducted at higher temperature showed significantly higher changes in conductivity and shorter response times. From a device perspective, charge transport properties and type of carrier in 2DEG (Two dimensional electron gas) is required to gain an understanding of the …
