This kept the Wagner and I am a director at Electronicsimulate this module with all the ICs intemperature of all of the ICs within a very Cooling Solutions in Santa Clara,place.

And in 2010, I joinedone of the requirements for this machine Electronic Cooling Solutions as a directorto work properly. EI: Okay. Final question. In the time of the company. that you have been an engineer, what EI: How did it benefit you as anare the biggest changes you have Engineer Innovation: What are youengineer to use Simcenter Flotherm XTseen?working on at the moment? for this project? GW: In the time I've been involved in GW: One of the most interesting projectsGW: Simcenter Flotherm XT allowed usengineering, the software has improved I've been working on is the cooling of ato model this learning module with theto the point where the output of the deep learning machine that uses neuralthousands of micro channels in the coldsimulation software looks just like the networks.
