TechAndComputer (Oct. 4, 2012) — Printed circuit boards (PCBs) are core components in every mobile phone, television and computer. PCBs can be thought of as acting like a nervous system, forming a network that links the microchips mounted on the board and supplies them with power. One of the most important methods of fabricating large PCBs involves the precision electroplating of copper onto the PCB panel immersed in an acidic electrolyte bath. However, some of the titanium parts used in the electroplating...

Smartphone application to allow instant polling for presidential debate Wednesday

  • PDF
TechAndComputer (Oct. 2, 2012) — When President Obama and Republican challenger Mitt Romney square off in their first debate October 3, college students across the country will pilot test a new smartphone application that promises to make live polling possible for the first time on a large scale.

So far more than 175 political science professors nationwide have registered some 12,000 students to field test the real-time polling app, developed by researchers at the University of...

Hotter might be better at energy-intensive data centers

  • PDF
TechAndComputer (Sep. 25, 2012) — As data centres continue to come under scrutiny for the amount of energy they use, researchers at University of Toronto Scarborough (UTSC) have a suggestion: turn the air conditioning down.

"We see our results as strong evidence that most organizations could run their data centers hotter than they currently are without making significant sacrifices in system reliability," says Bianca Schroeder, a UTSC assistant professor of computer...

TechAndComputer (Sep. 19, 2012) — An international team of scientists is rewriting a page from the quantum physics rulebook using a University of Florida laboratory once dubbed the coldest spot in the universe.

Much of what we know about quantum mechanics is theoretical and tested via computer...
