Transformer hot spot temperature prediction based on basic operator information
International Journal of Electrical Power & Energy Systems, 2021 A power transformer is an important component in power trains and electrical distribution networks. Predicting its life time is desirable, especially, if a zero downtime policy is applied.

Temperature Relaxation in Hot Dense Hydrogen [PDF]
Physical Review Letters, 2008 Temperature equilibration of hydrogen is studied for conditions relevant to inertial confinement fusion. New molecular-dynamics simulations and results from quantum many-body theory are compared with Landau-Spitzer (LS) predictions for temperatures T from 50 eV to 5000 eV, and densities with Wigner-Seitz radii r_s = 1.0 and 0.5.

Hot tearing behavior of NZ30K Mg alloy under progressive solidification [PDF]
China Foundry, 2021 Progressive solidification is usually considered an effective strategy to reduce the hot tearing susceptibility of a cast component. In this study, special constrained plate castings with progressive changes in cross-section were designed, which enabled ...

Managing Exertional Heat Stroke Among the Combatants [PDF]
Journal of Clinical and Diagnostic Research, 2017 Exertional Heat Stroke (EHS) is a medical emergency which when not addressed timely can lead to high mortality and morbidity. Armed forces are vulnerable to heat stroke because of their involvement in strenuous physical exercises in extremes of climatic

Skin Temperature in Hot Environment
Nippon Eiseigaku Zasshi (Japanese Journal of Hygiene), 1971 It has been suggested that the immersion of subjects into a hot water bath (Bath Method) may be useful and simple method for testing human heat tolerance. It is probable that the bath method may fail to evaluate valid heat tolerance because of the forced uniformization of skin temperature.

Evaluation of hot temperature extremes and heat waves in the Mississippi River Basin
, 2020 The Intergovernmental Panel on Climate Change (IPCC) reports that the changes in extreme events are expected to be detected earlier than changes in climate averages.

Contribution of mean climate to hot temperature extremes for present and future climates
, 2020 The occurrence of very high temperatures (hot extremes) is often linked with negative impacts in human health, natural ecosystems and the economy (e.g., energy, water supply and agriculture). Studies have invariably shown that the intensity and frequency

mSystems, 2022 Geographic isolation can be a main driver of microbial evolution in hot springs while temperature plays a role on local scales. For example, cyanobacteria, particularly high-temperature Synechococcus spp., have undergone ecological diversification along ...

Hot One‐Temperature Accretion Flows Revisited
The Astrophysical Journal, 2006 The effectiveness of the thermal coupling of ions and electrons in the context of optically thin, hot accretion flows is investigated. In the limit of complete coupling, we focus on the one-temperature accretion flows. Based on a global analysis, the results are compared with two-temperature accretion flow models and with the observations of black hole

Optimizing production efficiencies of hot water units using building energy simulations : trade-off between Legionella pneumophila contamination risk and energy efficiency [PDF]
, 2019 The energy needed for domestic hot water represents an important share in the total energy use of well-insulated and airtight buildings. One of the main reasons for this high energy demand is that hot water is produced at temperatures above 60°C to ...
