Chemical Pulse detonation engines

Pulse detonation engines (PDE) can achieve a maximum of 50% efficiency verus 30% for conventional jet engines Pratt & Whitney and General Electric now have active PDE research programs in an attempt to commercialize the designs with high pulse rates of 50-100 times per second to allow for less vibration. Some of the top scientists …

Microsoft concedes greater access to software required by the EU

Under Monday’s settlement, Microsoft said it would allow open-source software developers access to inter-operability information for work-group servers used by businesses and other large organisations. Other technology companies using this information will only have to pay a €10,000 ($14,300) one-off fee rather than a percentage of revenues from any software developed as a result. Also, …

FPGAs can accelerate repetitive computer operations up to 1000 times

FPGA processing accelerators have been developed. Warp processing” gives a computer chip the ability to improve its performance over time. Here’s how Warp processing works: When a program first runs on a microprocessor chip (such as a Pentium), the chip monitors the program to detect its most frequently-executed parts. The microprocessor then automatically tries to …

Samsung Develops New, Highly Efficient Stacking Process for DRAM

Samsung Electronics today announced that it has developed the first all-DRAM stacked memory package using ‘through silicon via’ (TSV) technology, which will soon result in memory packages that are faster, smaller and consume less power. The new wafer-level-processed stacked package (WSP) consists of four 512 megabit (Mb) DDR2 (second generation, double data rate) DRAM (dynamic …

Cluster State Quantum Computers

There has been a proof of concept using lasers to enable the first use of Deutsch’s Algorithm in a cluster state quantum computer. Cluster state quantum computers or one-way quantum computer are a scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states. (“A One-Way …

Scanning tunneling microscopes could get 500 times faster

A new nanoscale apparatus developed at JILA—a tiny gold beam whose 40 million vibrations per second are measured by hopping electrons—offers the potential for a 500-fold increase in the speed of scanning tunneling microscopes (STM), perhaps paving the way for scientists to watch atoms vibrate in high definition in real time. The new device measures …
