ECE graduate student Farah Fargo (center) received the Best Research Poster award at the 2014 IEEE International Cloud and Autonomic Computing Conference in London for her research in cloud computing and load-balancing systems. As more and more organizations realize the benefits of cloud computing -- reduced hardware costs, increased bandwidth, and anywhere, anytime access to data, for example -- engineers are tasked with developing technology to more effectively manage resources in the cloud.

One hurdle in cloud computing involves balancing power consumption and performance. As such, UA electrical and computer engineering graduate student Farah Fargo, in collaboration with ECE professor Salim Hariri and other graduate students, has introduced a real-time monitoring system that enables server hosts to dramatically reduce power consumption while maintaining quality of service....

As computers and telecommunications devices become more and more powerful, scientists and engineers around the world are constantly working to improve coding techniques that ensure reliable data transmission. University of Arizona electrical and computer engineering professor Bane Vasić, who recently received a Fulbright U.S. Scholar grant, is one of those researchers.

Vasić will join experts in Serbia at the University of Nis Faculty of Electronic Engineering, or ELEF, and in France at École Nationale Supérieure de l'Électronique et de ses Applications, or ENSEA, in spring 2015 to advance error correction code techniques. 

It is one thing to be able to transmit a multitude of different types of data over many kinds of devices. It is quite another matter to ensure that all the data arrives at its destination intact. Error correction techniques do just that -- make sure digital data sent over sometimes unreliable communication channels is received intact, despite any disturbances encountered along the way.

"The error correction codes that we as engineers build in communications or memory chips are a kind of grammar... Read Complete Article

ECE professor Linda Powers spoke to dozens of Engineering 102 freshmen and high school students during an October presentation about the vital role engineers play in cases of epidemic or pandemic outbreak.

As Ebola continues to pose national and international risks, engineers are being called on to design devices and processes that protect against the virus.  Linda Powers, electrical and computer engineering professor, is among the University of Arizona researchers contributing to preventative methods while also training the next generation of engineers to be prepared for global biomedical issues.

Powers spoke to dozens of Engineering 102 freshmen and high school students during an October presentation about the vital role engineers play in cases of epidemic or pandemic outbreak. ECE professor and Engineering 102 instructor Kathleen Melde said Powers, who is developing methods to advance the detection of... Read Complete Article

From left, ECE Professor Marwan Krunz and doctoral students Wessam Afifi and Hanif Rahbari (seated) analyze wireless transmission signals in the lab. Each day brings new revelations of risks to security and privacy on the Internet. News reports describe hackers stealing information from corporate networks, government agencies gathering metadata from personal cell phones, and smartphone manufacturers installing encryption software that law enforcement cannot crack.

You’d think everyone using a wireless device would be on high alert.

Yet many people still feel secure using their laptops or cell phones for, say, banking, sending email, playing video games or accessing medical records. After all, they’ve taken precautions to keep these activities private.

“People working on their laptops think ‘I am safe. I established a VPN. I have a password. I’m using encryption,’” said Marwan Krunz, UA College of... Read Complete Article
