Robin Bornoff FloVENT, FloTHERM’s sister product aimed at 3D CFD simulation of the built environment, has for many years been able to simulate the thermal behaviour of a data center. After all a data center is a built environment, albeit more for servers and the like than humans. We’ve not changed this capability of FloVENT but we have copied the relevant data centric features over to FloTHERM, extending … Read More

Patrick Carrier Power integrity (PI) is an analysis discipline that has been around for years.  Signal integrity (SI) has been around for a few more years.  Basically, they both deal with the proper analog operation of digital circuits.  So why these specific realms of analysis?  The main issue is that there is no such thing as “digital” – what we call “digital” data transmission is really … Read More

John McMillan You sent in the questions – Now lets get the answers ! Join me September 9, 2014 for our first Video Roundtable Q&A Event. I’ll be asking  the PADS Product Marketing Manager Jim Martens and Product Line Director Mike Griesbach the PADS VX questions YOU have submitted. Perhaps you’re already started using VX. Perhaps you’ve downloaded VX but have not started a new project … Read More

John Parry Come and join us for THERMINIC 2014 in (hopefully) sunny London! The 20th IEEE Workshop on THERMAL INVESTIGATIONS OF IC’s AND SYSTEMS (THERMINIC 2014) to be held at the magnificent World Heritage Site in Greenwich, London, is on 24-26 September. This year, as part of the 20th Anniversary celebrations, there will be a boat trip up the river Thames, followed by a trip around the London Eye! It’s a great … Read More

Michael Ford As humans, it is said that we consume between 2,000 and 2,500 calories per day of energy, 1,300 of which are used just to keep the body alive, including about 300 calories for the brain. The numbers vary from difference sources and of course are averages. Calorie consumption for the brain is said to range from 0.1 of a calorie per minute, up to around 1.5, probably the difference between watching the … Read More

Colin Walls As I mentioned on a previous occasion, I always welcome questions whenever I make a presentation, do a web seminar, write an article or blog post or whatever. Even very simple queries give me ideas for topics to discuss. I always take the view that, if one engineer poses a question, there are probably a bunch of guys who would also like the answer. Once again, I am turning my attention to C++ … What … Read More

John Day This probably shouldn’t be a surprise, but it’s an observation supported by research: younger people are a lot more interested in automotive connectivity than older people are, and they are even more interested in mobile connectivity – smartphones and the like. Lochbridge, formerly the Professional Services Division of Compuware, surveyed consumers ranging in age from 18 to 65 to assess their opinions … Read More

J VanDomelen On 22 Aug. 2014, Arianespace in France launched two satellites into orbit onboard a Russian Soyuz launch vehicle under contract with the European Space Agency (ESA) for its Galileo program. News that the launch vehicle failed to inject Galileo satellites 5 and 6 into the correct orbit rocked the military and aerospace (mil/aero) community this month. “Observations taken after the separation of … Read More

J VanDomelen Arianespace in France launched two satellites on the Russian Soyuz ST rocket. Telemetry data soon revealed that the spacecraft were placed in elliptical (rather than circular) orbit and in a lower orbit than anticipated; as a result, the satellites are operationally redundant, aerospace engineers indicate. Arianespace officials found that an anomaly occurred during “the flight phase involving the [Russian] … Read More

Robin Bornoff Electronics thermal simulation historically focussed on steady state conditions, worse case scenarios where for example a power dissipation is assumed at a maximum and unchanging. Not a direct reflection of reality but the conservative (over)temperature simulation results enabled design margins to be implicitly factored in. Over the years, as margins reduced and the need for ever more accurate simulations … Read More

J VanDomelen Europe is in the process of assembling a civilian-operated satellite navigation system, designed to deliver greater precision than the U.S.’s Global Positioning System (GPS) satellite constellation, to the tune of 5.4 billion Euro. The full project calls for 30 modern satellites to be positioned precisely into orbit over the next few years. This week, however, the European Space Agency (ESA) hit a snag … Read More

J VanDomelen European Space Agency (ESA) officials in Paris reported this week an error—specifically, an orbital injection anomaly—in the launch of its two latest satellites under the Galileo program. Galileo, Europe’s global navigation satellite system, is intended to provide accurate, guaranteed global positioning that is under civilian control. It is interoperable with the United States’ Global Positioning System … Read More

It's Electrifying!

Posted by Shelly Stalnaker

Shelly Stalnaker I have one opinion about electricity…if it’s invisible and it can kill you, it’s probably a good idea to avoid it. Now, some of my attitude is shaped by spending most of my childhood along the US Gulf Coast, where massive thunderstorms are an almost-daily occurrence during summer, and every little kid is taught to run for cover at the first rumble or flash. But that healthy fear means … Read More

J VanDomelen SpaceX has been making a big splash recently with the release of the revolutionary Dragon Version 2. Never before has this military and aerospace (mil/aero) geek seen such a futuristic design that is fully functional. The new Dragon v2 is a major leap forward in manned spaceflight. It features many new, advanced, and life-saving features that this geek will highlight as we explore the Dragon v2 in this … Read More

Hot Days of Summer

Posted by Nazita Saye

Nazita Saye I moved to England 10 years ago – actually it’ll be 10 years come September 1st. During this time I have seen rain, rain and even more rain. I’ve even lived through some tepid winters and downright cold summers.  In fact, I’ve adopted an endearing habit of the English and have become obsessed with the weather. Take last year for example. We had some nice weather in April (chilly but with warm sun so … Read More
