Heating patterns in English homes: national survey vs common model assumptions
Hightlights of this open access article published in Building and Environment:
• Building stock models need to revise some of their assumptions on space heating.
• Weekends and weekdays are similar in their heating pattern and duration.
• Estimated heating demand temperature is slightly lower than the assumed 21 °C.
• Homes differ widely in their hours of heating and their demand temperature.

Dear all
i have question that i woud like to know about principle of putting monetary value on human to rduce risk and the principle of weighting the importance of risk , moreover is there any conflic between these principle

Crack length measurement
I am trying to measure J - integral from experiment. " Let my initial fatigue crack length is 6mm, then i did single specimen unloading compliance test on it. The crack legth increased to 8mm" If i want to model the same geometry in FEA. Now my doubt is that "what carck length should i take 1) Initial fatigue crack = 6mm 2) final crack length = 8 mm.................... Note: I need to model my CT specimen in FEA to correct my experiments :-)

Eighty Years of Dislocation Theory and Work Hardening
On February 7, 1934, two consecutive papers by Sir Geoffrey Ingram Taylor were received and so the dislocation theory was born and the first attempt at describing work hardening was made. Before that date, it was known that there was a big gap between the ideal and the experimentally observed shear strength. While according to the calculations, the shear strength had to be of the order of one tenth (or with finer models one thirtieth) of the shear modulus, the measured shear strength was several orders of magnitude smaller. This large discrepancy brought about Geoffrey I.Taylor, Egon Orowan and Michael Polyani to independently postulate the existence of dislocations. Papers by Orowan and Polyani were published consecutively in one volume of Zeitschrift für Physik.
Caltech: secrets of the world’s number one university
Good International news on Caltech and engineering. Ares Rosakis, chair of the Division of Engineering and Applied Science,describes Caltech as “a unique species among universities…a very interesting phenomenon”.More can be found in the attachment or at the link below
