Bottlenecks and Interface Materials; Part 2 - When TIMs Go Bad

Posted Jan 30, 2012, by Robin Bornoff

‘Bits stuck onto other bits’, a succinct definition of an electronic product, if not a product that contains electronics. Soldering is the method of choice for getting the components to attach to the pcb, the layered board that contains the metallic traces connecting component pins to other component pins. Rivets, welds, screws or bolts for the chassis, some form of gluing or sticky adhesion … Read More

Is Pipe Insulation Effective?

Posted Jan 17, 2012, by Travis Mikjaniec

It’s that time of the year, when the weather turns cold and people start to think about winterizing their home to reduce heating costs.  Usually it takes the first winter heating bill to provide the motivation to undertake this task.  With this in mind, I would like to talk about pipe insulation.  Specifically, the foam wrap insulation you can find at any hardware store (http://www.homedepot.com/h_d1/N-5yc1v/R-202318552/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053)   In … Read More

Not a Good Day

Posted Nov 22, 2011, by Nazita Saye

Have you ever had one of those days where it would have been better to have stayed in bed with the duvet pulled up firmly above your head? I’m sure most of us have had those kinds of days. Last week I was suffering from this malaise. I curbed the front wheel of our new car on the way to work, I dropped my breakfast bagel after taking the first bite (and yes a dropped bagel exhibits the same behavior … Read More

What! All that just for that? The bonkers world of CPU cooling.

Posted Nov 17, 2011, by Robin Bornoff

My colleague Ed and I were marvelling the other day at the CPU cooling unit from one of our training desktop PCs undergoing a repair. “What, all that just for that!?”. The CPU itself was but a small square wafer compared to the behemoth that was the ducted fan and heatsink with integral heatpipes mounted on top of it. Whereas transistor sizes are measured in nanometres cooling systems can … Read More

The ROI of Concurrent Design with CFD

Posted Sep 16, 2011, by Nazita Saye

For the past few months I’ve been working behind the scenes on a very exciting project. I’ve been working with the good folks at the Aberdeen Group, a leading Product Lifecycle Management (PLM) industry consulting and research organization, to better understand the ROI of using simulation -- specifically CFD. Of course as a leading developer of CFD software we inherently understand the value of simulation … Read More

Back to School

Posted Sep 5, 2011, by Nazita Saye

Today is the first day of school in England. How do I know that? My first clue was the morning drive to work went back to 60 minutes. The second clue was the diversion/roadworks signs that popped up overnight as the city started tearing up roads in earnest again. The third and final clue was seeing lots of bleary-eyed kids in new school uniforms waiting to catch buses to school. Image courtesy of Microsoft … Read More

This Old CFD House: Part V

Posted Aug 9, 2011, by John Wilson

Welcome to Part V of a multi-part series, where in this installment Travis takes a look at his lawn mower. One of my first jobs as a new home owner was to mow the lawn.  As it happens, we had a friend with a lawn mower that was no longer using it, so he gave it to us.  When I went to pick it up, he was using words like, 1992, and “never maintained”, so I knew it wasn’t going to be a super awesome lawn … Read More

Smart Phones and Gadgets - the New Nemesis of Avionics

Posted Jul 4, 2011, by Nazita Saye

I don’t particularly care for airports. You rush to get to them. You rush thru check-in and push your way thru never-ending queues to go thru security and get the prerequisite pre-boarding massage (I seem to get pat downs as I go thru security a lot and even though I gladly submit to them I’m starting to think that they are a new service that the airlines provide and thus deserve a proper marketing … Read More

This Old CFD House: Part IV

Posted May 26, 2011, by John Wilson

Welcome to Part IV of a multi-part series, where in this installment Travis continues the “virtual” look at his crawlspace. In the previous installment of “this old CFD house”, we started to peel back the veil on my crawlspace and its moisture issue.  I analyzed the problem as it is, and we made some enlightening findings.  First, really the only way air is getting into the crawlspace is … Read More

This Old CFD House: Part III

Posted May 19, 2011, by John Wilson

Welcome to Part III of a multi-part series, where in this installment Travis takes a “virtual” look at his crawlspace. For this next installment of “this old CFD house”, and really the entire reason I started this blog series, I’d like to take a look in my crawlspace. Now, from what I understand, Feng Shui says running water is good for wealth. Well the opposite is true when you have … Read More
