Evaluating Overheating Preventative Measures in Residential Buildings and Passive Survivability
… the probability of heat-related illness and overheating. Assessments within this research are within a two-story residential building. The outdoor weather data selected for the assessments is from New York, NY during an extreme hot week. Assessments made within this research are intended to …

INDOOR OVERHEATING RISK: A FRAMEWORK FOR TEMPORAL BUILDING ADAPTATION DECISION-MAKING
Overheating in buildings is predicted to increase as a result of a warming climate and urbanisation in most cities. With regards to responding to this challenge, decision makers ranging from_ design teams, local authorities, building users, national programs and market innovators; and during the …

Aircraft noise, overheating and poor air quality in London primary schools' classrooms
… noisy areas (e.g. Heathrow airport) suffer from overheating and poor air quality as well as a high level of background noise during summer periods, due to the lack of ventilation. The main means of ventilation in majority of the UK schools is window. In noisy areas, the classrooms' occupants …

Studying water-wedging as a cause for short term overheating in the boiler of a coal-fired power plant
… boiler systems is referred to as short term overheating (STO). This phenomenon occurs when the tube is heated to higher than its design temperature in a short period of time, causing a ductile failure of the tube material. The superheaters are particularly susceptible to STO. Such a failure …

Viability of naturally ventilated buildings in the UK under predicted future summer climates
… This has potentially serious implications for overheating of naturally ventilated office buildings, many of which already fail to perform under current heatwave conditions. This thesis addresses the summer performance of such buildings under current and future climates by means of building …

Towards Nearly Zero Energy Buildings in Lebanon: Bioclimatic Design and Experimental Strategies
… and materiality that will minimise internal overheating, and thus reduce or eliminate cooling energy loads for summer comfort in apartment buildings in Lebanon. To reach this aim, the research starts by monitoring existing apartment buildings, followed by calibrated software-based temperature …

Low Density 2D-Electron Sheets on Liquid 3He Surfaces
… ("boundary"). Another explanation could be overheating effect or sliding mode of Surface State Electrons, when electron layer was near decoupled from helium surface. In our opinion, it is most probable explanation. We also did measurements below temperature of the superfluid point …

Stability and quench protection of high-temperature superconductors
… that can occur in large-scale "real" devices: 1) overheating; 2) high voltage; and, 3) overstressing. In this thesis, we have investigated the first two issues as well acoustic emission (AE) technique as a possible mean for an early detection of a quench. For most of the experimental work reported …

Vibrational energy transfer in condensed high explosives: Nitromethane
… vibrational cooling, substantial transient overheating is observed in the high energy vibrations in the 900-1400 cm$\sp{-1}$ range. Overheating refers to instantaneous vibrational quasitemperatures which are temporally greater than the final temperature of the bulk liquid. The overheating …

Price Level of Non-tradable Goods in Iceland: Explanations by Economic Fundamentals
… financial sector expansion had led to economic overheating which contributed to pushing up non-tradable price against tradable goods. This, in turn, caused nontradable goods in Iceland to appreciate against those in countries that were not experiencing a comparable overheating. This is a classic …

Monte Carlo Methods for Reliability Analysis and Power Estimation
… Since excessive power dissipation causes overheating and can lead to soft errors and permanent damage, attempts to achieve first-pass reliability require accurate and efficient power estimation. With today's closer customer interaction, many circuits are being designed for already existing …

Transport mechanisms and wetting dynamics in molecularly thin films of long-chain alkanes at solid/vapour interface : relation to the solid-liquid phase transition
… paths from were the material was collected. Both overheating and droplet movement can be explained by the fact that the alkane melt wets only partially its own solid. For the first time, these results explicitly confirm the supposed connection between the absence of overheating in solid and …

An Investigation of Heat Transfer to the Implant-Bone Interface and Marginal Gingiva During Preparation of Implant Abutments in the Mouth: in vitro study
… were prepared without air-water cooling, extreme overheating was provoked, reaching the critical temperature that would lead to irreversible bone damage within only a few seconds. But ZirAceTM Abutment was not the same. Especially, in the middle and apex area, extreme overheating was not found …

Accounting for carbon impacts in buildings: a rating procedure
… by thermal mass, air velocity and shading. Overheating makes active cooling necessary in a dwelling, resulting in an increase in operational GHG. Therefore, future quantities of GHG are highly dependent on future climate and the need for air conditioning. Room function also impacts …

Energy Efficient Passenger Comfort in Underground Subway Environments
… However, deep and old subway systems suffer from overheating problems, because they were built before the invention of modern mechanical ventilation and air conditioning, resulting in passenger discomfort and health issues during summer conditions (Gilbey et al., 2011). These systems were not …

The characteristic of frequency response on winding faults and configurations of transformer
… are inter-turn short circuit (SC) fault, local overheating and radial deformation. The results show that the SC causes the starting magnitude to increase and the resonance at the low frequency region to shift towards higher frequencies. Meanwhile, during local overheating fault, the winding …
