April 2021 214 Emirates Aviation University (EAU), a leading educational institution for aeronautical and aviation studies in the Middle East, has introduced a wind tunnel to its facilities with a grant from Boeing Middle East.    The new wind tunnel will give students practical and experimental learning opportunities to examine flow physics around aircraft and other vehicles and machines.   Over 400 undergraduate and postgraduate students at EAU’s School of Engineering will benefit from the new wind tunnel. As a teaching tool, it will enable them to conduct experiments under diff...

April 2, 2021 The most obvious way to verify compliance of fenestration products with code requirements for structural strength under wind pressure loading, often based on commercial-grade requirements of the North American Fenestration Standard, is laboratory testing. However, when a specific project calls for non-standard configurations such as larger or smaller sizes, variations in framing configuration or higher wind pressure levels than those of the tested baseline assembly, it can be prohibitively expensive and time-consuming to test all such variations. Accordingly, the Fenestration &...

What you do. >> people heard explosions. do we know what that was -- >> so i can't speak to the explosions that they may have heard. when you have incidents like this, large circuit breakers, which are the high-voltage equipment of circuit breakers in a panel in your house, operate. and they are very loud when they operate. that could have been what they heard, but i can't know for sure because there were restoration attempts made. >> were there fires in the manholes at any point. >> i did hear a report of a fire in a manhole. we'll investigate. very unlikely that fire in a manhole was the cau...

Those. she joins us now. any word yet on what exactly cause of all of this? good morning. >> reporter: good morning, martin. well, we heard from mayor de mr blas yoe of what they thought was a preliminary car. let's listen to what the mayor said. >> it's something within the normal electrical grid, obviously something didn't work, but no other kind of external influence here. this appears to be something that just went wrong in the way that they transmit power from one part of the city to another to address demand. >> reporter: and so there you heard what they think is the initial cause. k con...

>> oh, yeah, those are the cheers across the city the moment the lights started coming back on. . the outage knocked out power in some of manhattan's most popular tourist districts including times square and broadway. >> according to the city's utility district, con edison, 72,000 customers, many more people, were without power at one point. >> cnn's athena jones is with us now. any word on what caused it yet? >> reporter: good morning. con ed will be investigating this. their ceo said they're going to do a full engineering analysis to get to the bottom of what caused this outage that lasted a...
