Defkalion will stay quiet until product is certified and a review of energy projects that have failed to deliver

Defkalion is shutting down its forum. Defkalion claims that their next announcment in a few months (presumably with a press release and press conference) will be that of a successful and certified product. Defkalion may or may not deliver in a few months or later this year or next. We will see. Blacklight Power is …

Challenges of Exascale Computing by Nvidia Chief Scientist

Challenges of Exascale Computing by Nvidia Chief Scientist (45 pages) Instruction level parallelism (ILP) was mined out in 2000. Historic scaling is at an end! To continue performance scaling of all sizes of computer systems requires addressing two challenges:Power and Programmability. Much of the economy depends on this. Now voltage is held nearly constant Halve …

Watch a lot less TV and exercise for a substantially longer life

Watching TV for an average of six hours a day could shorten the viewer’s life expectancy by almost five years, indicates research published online in the British Journal of Sports Medicine. The impact rivals that of other well known behavioural risk factors, such as smoking and lack of exercise. Other research has shown that lifelong …

Dramatic simplification paves the way for building a quantum computer

Controlling arbitrary quantum operations using additional degrees of freedom. (a) Logic circuit in which quantum operation O is implemented on a register of qubits (target register), conditional on the logical state of a single control qubit. (b) Our approach to implementing the circuit in (a). The target information carriers are four dimensional systems with logical …

Replacing time with numerical order of material change resolves Zeno problems of motion

With clocks, we measure the numerical order of a material change, i.e., motion running in space. There is no experimental evidence that clocks measure time. It is convenient to replace the concept of time with the numerical order of material change. This view corresponds more adequately to the physical world and resolves Zeno problems of …

Next-generation LTE base stations speed mobile connectivity with SDRs, hard-coded accelerators, and multicore CPUs and smartphones will use integrated processors

DSP chips are powering the race to 4G in next generation base stations Next-generation base stations speed mobile connectivity with SDRs, hard-coded accelerators, and multicore CPUs. EDN covers the DSP, FPGA technology that is going into the new base stations. To build a 4G modem, you must start with the PHY (physical) layer, Layer 1 …
