TechAndComputer (Oct. 11, 2012) — Researchers from the University of Seville (Spain) have used mathematical tools to assess what has been known for centuries: the temperature inside the typical Mediterranean courtyard is cooler than that of the street. Though seemingly common sense, understanding such information in detail helps to save energy and money, which is the objective of eco-efficient buildings.

The inhabitants of Mediterranean regions have known for centuries that during the summer their courtyards are cooler than the street. "Why then put air conditioning...

TechAndComputer (Oct. 9, 2012) — Arizona State University researchers have developed a new software system capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to roads and individual...

Multi-photon approach in quantum cryptography implemented

  • PDF
TechAndComputer (Oct. 3, 2012) — Move over money, a new currency is helping make the world go round. As increasing volumes of data become accessible, transferable and, therefore, actionable, information is the treasure companies want to amass. To protect this wealth, organizations use cryptography, or coded messages, to secure information from "technology robbers." This group of hackers and malware creators increasingly is becoming more sophisticated at breaking encrypted information...

Mathematics of leaf decay: A mathematical model reveals commonality within the diversity of leaf decay

  • PDF
The colorful leaves piling up in your backyard this fall can be thought of as natural stores of carbon. In the springtime, leaves soak up carbon dioxide from the atmosphere, converting the gas into organic carbon compounds. Come autumn, trees shed their leaves, leaving them to decompose in the soil as they are eaten by microbes. Over time, decaying leaves release carbon back into the atmosphere as carbon dioxide.

Researchers developing 'BIGDATA' toolbox to help genome researchers

  • PDF
TechAndComputer (Oct. 3, 2012) — Today's life scientists are producing genomes galore. But there's a problem: The latest DNA sequencing instruments are burying researchers in trillions of bytes of data and overwhelming existing tools in biological computing. It doesn't help that there's a variety of sequencing instruments feeding a diverse set of applications.

Iowa State University's Srinivas Aluru is leading a research team that's developing a set of solutions using high...
