A boost to your mobile signal

  • PDF
Jan. 25, 2013 — When using your mobile phone, it doesn't take much to lose that precious signal -- just turning a corner or riding on a train can be enough. EU-funded research is developing new technologies to eradicate those annoying 'black holes' in wireless coverage, while freeing up some mobile network capacity at the same time.

We live in a 24/7, always-on, mobile and wireless world. Wherever we go we are connected -- to each other, to the web, to all our favourite apps, to whatever data we need, exactly when we need it.

Or so we like to think. The reality is quite different. There are corners of our homes where the web won't work. There are black spots in towns and huge holes in the wireless network in more...

Common data determinants of recurrent cancer are broken, mislead researchers

  • PDF
Jan. 2, 2013 — In order to study the effectiveness or cost effectiveness of treatments for recurrent cancer, you first have to discover the patients in medical databases who have recurrent cancer. Generally studies do this with billing or treatment codes -- certain codes should identify who does and does not have recurrent cancer. A recent study published in the journal Medical Care shows that the commonly used data determinants of recurrent cancer may be misidentifying patients and...

Information overload in the era of 'big data'

  • PDF
TechAndComputer (Aug. 20, 2012) — Botany is plagued by the same problem as the rest of science and society: our ability to generate data quickly and cheaply is surpassing our ability to access and analyze it. In this age of big data, scientists facing too much information rely on computers to search large data sets for patterns that are beyond the capability of humans to recognize -- but computers can only interpret data based on the strict set of rules in their...

Cyber security risk to smart grids and intelligent buildings

  • PDF
TechAndComputer (Aug. 13, 2012) — Building owners and designers, and particularly members of the building services industry, are racing to implement intelligent buildings and smart grids, which are widely heralded as a boon in terms of both energy efficiency and facilities management. But many are overlooking the potential risk of malicious attacks on these highly networked control systems. Share This: See Also: Matter & EnergyConstructionEnergy TechnologyCivil...

Autonomous robotic plane dodges obstacles when flying indoors

  • PDF
TechAndComputer (Aug. 10, 2012) — For decades, academic and industry researchers have been working on control algorithms for autonomous helicopters -- robotic helicopters that pilot themselves, rather than requiring remote human guidance. Dozens of research teams have competed in a series of autonomous-helicopter challenges posed by the Association for Unmanned Vehicle Systems International (AUVSI); progress has been so rapid that the last two challenges have involved indoor navigation...
