What do you call someone who doesn't believe in Father Christmas? A rebel without a Claus. Right, that's that out of the way. This week Facebook announced that it plans to build a 3x 300,000 ft^2 data centers in Lulea, Sweden. The Lulea business agency who helped attract Facebook to their city are dutifully excited as should Facebook be as they look set to capitalise on 10 … [Read more...]
All Detailed Thermal IC Package Models are Wrong… Probably
'Rubbish In -> Rubbish Out' is a well accepted fact in the world of simulation. Regardless of the technical capabilities of your thermal simulation tool, the accuracy of prediction will always be tightly coupled to the accuracy of the input data. The most accurate thermal IC package model is a so called 'detailed' model where all the internal construction is represented … [Read more...]
Underfloor Electric Heating. Part III – Penny wise, pound foolish.
It would only have cost me an extra £170, a small extra compared to the cost of the rest of the build, but I decided against laying thermal insulation boards directly under the underfloor electric heating mats. Surely better to leak some of the heat down to heat the 100mm thick concrete screed which would maintain its heat through those cold winter weeks, giving thermal support … [Read more...]
Are You Profiting From the Global Growth of Mobile Buyers?
If you target buyers outside North America, you may find recent Forrester research and forecasts regarding worldwide mobile Internet access interesting. Forrester forecasts that by 2014, 65% of the world’s population will own at least one active mobile phone. And, earlier this year, Mary Meeker of venture capital firm Kleiner, Perkins, Caufield & Byers stated that we have … [Read more...]
Engineers Create Polymer Light-Emitting Stretchable Devices
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have demonstrated an intrinsically stretchable polymer light-emitting device. They developed a simple process to fabricate the transparent devices using single-walled carbon nanotube polymer composite electrodes. The interpenetrating networks of nanotubes and the polymer matrix in the surface layer … [Read more...]
