A Model of Heat Conduction

open access: yes, 2008
We define a deterministic ``scattering'' model for heat conduction which is continuous in space, and which has a Boltzmann type flavor, obtained by a closure based on memory loss between collisions.

Heat Transfer Modeling of Hydrogen-Fueled Spark Ignition Engine

open access: yesEnergies
Currently, green hydrogen, generated through renewable energy sources, stands out as one of the best substitutes for fossil fuels in mitigating pollutant emissions and consequent global warming. Particularly, the utilization of hydrogen in spark ignition

Performance of a building integrated collector for solar heating and radiant cooling [PDF]

open access: yes, 2011
Due to their limited temperature range, unglazed solar collectors have long been relegated to providing low cost heating in applications such as swimming pool heating systems.

A role for glyceraldehyde-3-phosphate dehydrogenase in the development of thermotolerance in Xenopus laevis embryos [PDF]

open access: yes, 1988
During heat shock, Xenopus laevis embryos exhibit an increase in the rate of accumulation of lactate and a loss of ATP relative to non-heat- shocked control embryos.

Assessing the Relationship between Measurement Length and Accuracy within Steady State Co-Heating Tests

open access: yesBuildings, 2017
Evidence of a fabric performance gap has underlined the need for measurements of in situ building performance. Steady state co-heating tests have been used since the 1980s to measure whole building heat transfer coefficients, but are often cited as ...

Smooth bumps, a Borel theorem and partitions of smooth functions on p.c.f. fractals

open access: yes, 2009
We provide two methods for constructing smooth bump functions and for smoothly cutting off smooth functions on fractals, one using a probabilistic approach and sub-Gaussian estimates for the heat operator, and the other using the analytic theory for p.c ...

Heat loss through the window frames of buildings

open access: yesИнженерно-строительный журнал, 2019
The object of investigation is window frames of buildings since they are critical zones in terms of thermal insulation. It was studied how the properties of window frame affect the change in heat flow and temperature fields. It was analyzed the heat loss

Analytical approach to ground heat losses for high temperature thermal storage systems [PDF]

open access: yes, 2019
A new approach to estimate the heat loss from thermal energy storage tank foundations is presented. Results are presented through analytical correlations based on numerical solutions for the steady-state heat conduction problem for thermal energy slab-on-

Performance of natural, exhaust, demand controlled exhaust and heat recovery residential ventilation systems as prescribed by the standards in 5 European countries [PDF]

open access: yes, 2013
Over the last decades, residential ventilation standards have been integrated in most of the buildings codes of European countries. Contrarily to the consolidation effort in the development of the nonresidential ventilation standard EN 13779, most of the
