A pronounced effect of overheating is observed on the crystallization behavior for the three zirconium-based bulk metallic glasses: Zr41.2Ti13.8Cu12.5Ni10Be22.5 , Zr57Cu15.4Ni12.6Al10Nb5 , and Zr52.5Cu17.9Ni14.6Al10Ti5 . A threshold overheating temperature is found for each of the three alloys, above which there is a drastic increase in the undercooling level and the crystallization times. Time...

Previously we identified the receding flow, where two fluid streams recede from each other, as an open numerical problem,1 because all well-known numerical fluxes give an anomalous temperature rise, thus called the overheating problem. This phenomenon, although presented in several textbooks,2,3 and many previous publications, has scarcely been satisfactorily addressed and the root cause of the...

Climate heat waves occurring in urban centers are a serious threat to public health and wellbeing. Historically, most heat-related mortalities have arisen from excessive overheating of building interiors housing older occupants. This paper developed an approach that combines the results simulation bioheat models generate health-based limit criteria for long-term care homes (LTCHs) by which body...

There is growing concern in Western Europe that higher insulation and air tightness of residential buildings leads to increased overheating risk. This paper discusses temperature monitoring from identical houses in the Southwest of the UK that were built to low energy standards (Code for Sustainable Homes Level 5). The temperature data were analysed using both established static overheating cri...

Recent climate change projections estimate that the average summertime temperature in the southern part of Great Britain may increase by up to 5.4°C by the end of the century. The general consensus is that projected increases in temperature will render British dwellings vulnerable to summer overheating and by the middle of this century it may become difficult to maintain a comfortable indoor en...

Heatwaves have well described impacts on human health and wellbeing. Heatwaves also have impacts on hospitals; patients, visitors, equipment, medication and information technology systems have all been affected or compromised during episodes of extreme heat. High indoor temperatures are also of concern for the comfort, efficiency, and occupational health of staff. The Heatwave Plan for England ...

Indeed, a nominal appreciation may help reduce reserve inflows and allow for a more autonomous monetary policy in the case of overheating. A plausible strategy would be a small one-step revaluation, which would bring the renminbi to parity with the Hong Kong dollar. However, such an adjustment may provoke additional speculative capital inflows and is not even necessary to bring about the real a...

The estimation of harmonic components of power voltage signals is one of the measurements prescribed by the power quality (PQ) standards (IEC 61000-4-30, 2008). In general, the harmonic components originate from non-linear elements connected to the power system such as non-linear loads (e.g., switched-mode power supplies) or transformers. An example of a distorted voltage measured in an office ...

In this study, we combined different physico-chemical methods to show the effect of overheating on the quality of golden fry cooking oil. Those methods include spectroscopic methods such us 1H-NMR, 13C-NMR and FTIR. Results showed that both overheating and excessive reuse of golden fry cooking oil seriously affected its quality by increasing its density, viscosity and different indexes like ref...

designing an efficient skin for the building can minimize winter heat loss and summer heat gain. double skin façade (dsf) is a good device for achieving such a goal; but its summer overheating is a problem for using it, especially in hot-dry climates such as iran plateau. in this study, after reviewing state of the art strategies for cooling façade cavity, the effect of using some of them (such...
