If gravitons are super-strong interacting particles and the lowtemperature graviton background exists, the basic cosmological conjecture about the Dopplerian nature of redshifts may be false. In this case, a full magnitude of cosmological redshift would be caused by interactions of photons with gravitons. Non-forehead collisions with gravitons will lead to a very specific additional relaxation ...

We introduce the concept of energy per operation as a measure of performance of an asynchronous circuit. We show how to model energy consumption based on the high-level language speciication. This model is independent of voltage and timing considerations. We apply this model to memory design. We show rst how to dimension a memory array, and how to break up this memory array into smaller arrays ...

Low-energy supersymmetry is a theoretical extension of the Standard Model of particle physics in which supersymmetry is invoked to explain the origin of the electroweak scale. In this approach, the energy scale of supersymmetry breaking can be no larger than about 1 TeV. In these lectures, a pedagogical account of softly broken supersymmetric gauge theories is presented. The minimal supersymmet...

Sustainability and the UK cement industry Traditional Portland cement-based concrete provides the foundation for the built environment. Buildings constructed appropriately and imaginatively from this material can and do exhibit an impressive array of properties [1] especially those that have been designed to optimise the thermal mass of concrete [2]. This type of concrete building is expected t...

We discuss our tools and techniques to monitor and inject packets in Bluetooth Low Energy. Also known as BTLE or Bluetooth Smart, it is found in recent high-end smartphones, sports devices, sensors, and will soon appear in many medical devices. We show that we can effectively render useless the encryption of any Bluetooth Low Energy link.

energy conservation in buildings plays a vital role for sustainable development of societies and nations. although, newer buildings in developing nations are being constructed using energy conservation approach, existing buildings have higher energy demand to meet the desired comfort. excessive energy demand for cooling the built environment is a major problem over most of the arid climatic zon...

Ask a group of particle theorists about low energy hadron physics and they will say that this is a subject that belongs to the age of the dinosaurs. However, it is GeV physics that controls the outcome of every hadronic interaction at almost every energy. Confinement of quarks and gluons (and any other super-constituents) means that it is the femto-universe that determines what experiments dete...

Character and Role of Theory Storms’ view of where and how low energy nuclear reactions (LENR) occur has been called a theory, so we begin with an examination of the character of a scientific theory. A compact summary about theory in any science is available in Wikipedia: “A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that ...
