Feeling organs via a display screen

Computerized image analysis is used to extract information from images. It can be used in medical applications to determine the size of organs or to build 3-D models of organs before surgery. For example, a PhD candidate at Uppsala University, Sweden, has developed new technology to make easier to diagnose...

Stochastic Equilibrium Modeling of the TCP Dynamics in Various AQM Environments

This paper proposes stochastic packet level models for the NewReno and Tahoe versions of TCP during persistent data transmission. It is shown how throughput and the risk of experiencing time-out depend on the packet error probability. The paper shows how this error rate could be interpreted under different variants of...

Spatial Multiplexing for Outdoor MIMO-OFDM Systems With Limited Feedback Constraint

This paper proposes a spatial multiplexing technique for the downlink of a Multiple-Input-Multiple-Output MIMO Orthogonal-Frequency-Division-Multiplexing OFDM system. For outdoor environments with a limited angular spread at the base station, the proposed technique is able to separate the users' streams through a joint spatial processing at both the transmitter and the...

LHC scientists get death threats

So it's come to this: Death threats against physicists. About what? The earth-destroying Large Hadron Collider, of course. Such is the angst that the American Nobel prize winning physicist Frank Wilczek of the Massachusetts Institute of Technology has even had death threats, said Prof Brian Cox of Manchester University,...

Enterprise password management really isn't a good idea

Being at a university and working for a government department allows me to understand this concept well. There are shared resources here, there and everywhere, provided by different people and providers, all open to a "certain type" of person - employees or students.

From Chapter Two: The appliance computing culture

The appliance computing culture earned its successes by focusing on the revenue generation side - and that, in turn, drove its own evolution to database technology, the "application as interfaces to data" view, and tight evolutionary links between University research groups and companies like DEC and DG. by Paul Murphy

A virus in our genes, think about that....

Really fascinating news: Virus is passed from parent to child in the DNA. Researchers found that roseola, an infection that everyone apparently gets but only 20 percent of children develop the characteristic rash that gives it its name, is actually in our DNA. It co-evolved into us, which raises some...
