A simple way to help cities monitor traffic more accurately

  • PDF
TechAndComputer (Aug. 7, 2012) — Cities count the number of cars on the road in order to plan everything from the timing of stoplights to road repairs. But the in-road metal detectors that do the counting can make errors -- most often by registering that a car is present when one isn't.

One common error is called "splashover" because it usually involves an over-sensitive detector picking up the presence a vehicle in...

Paving the way to a scalable device for quantum information processing

  • PDF
TechAndComputer (July 24, 2012) — Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits (qubits). The research, published in Nature Nanotechnology, shows how it is possible to realise this device embedded in a semiconductor chip, and demonstrates the device's ability to confine individual ions at the nanoscale.

As the UK's National Measurement Institute, NPL is...

Math formula leads researchers to source of pollution

  • PDF
TechAndComputer (June 25, 2012) — The leaking of environmentally damaging pollutants into our waters and atmosphere could soon be counteracted by a simple mathematical algorithm, according to researchers.

Presenting their research June 26, in IOP Publishing's journal Inverse Problems, the researchers, from Université de Technologie de Compiègne, believe their work could aid efforts to avoid environmental catastrophes by identifying the exact location where pollutants have been...

Android vulnerability debugged

  • PDF
TechAndComputer (Apr. 12, 2012) — A group of Italian researchers have discovered and neutralized a serious vulnerability present in all versions of Android, the popular operating system developed by Google specifically for smartphones and tablet computers. The vulnerability could have been easily exploited by malicious software applications, with the effect of making devices based on Google's operating system currently on the market completely unusable. The solution proved to be...

Smart way of saving lives in natural disasters

  • PDF
TechAndComputer (Jan. 4, 2012) — Smartphones could help save hundreds of thousands of lives in the aftermath of a disaster or humanitarian crisis, research from University of Manchester academics has found.

Software developed by computer scientists could help to quickly and accurately locate missing people, rapidly identify those suffering from malnutrition and effectively point people towards safe zones simply by checking their phones.

It is...
