  • Power management is, literally and metaphorically, the hottest area in computing and computing appliances. In 1965, while working at Fairchild Semiconductor, Gordon Moore predicted that the number of transistors in an integrated circuit would double approximately every two years. Moore’s law, as his observation has been dubbed, has so far been the foundation of the business of per- sonal computing and its derivative applications.

  • Power electronics is the technology of processing and controlling the flow of electric energy by supplying voltages and currents in a form that is optimally suited to the end-user’s requirements [1].Atypical block diagram is given in Figure 1.1 [2]. The input power can be either AC and DC sources. A general example is one in which the AC input power is from the electric utility. The output power to the load can be either AC and DC voltages. The power processor in the block diagram is usually called a converter. Conversion technologies are used to construct converters.

  • The newest waste management technology is bioconversion using fly larvae converting organic waste to insect larval biomass and organic residue. Bioconversion is a practice of recovering resources while simultaneously limiting the amount of organic material affecting landfill behaviour. Several organisms have been used in this treatment process. Several studies have been done using the black soldier fly larvae to degrade organic material.

  • Without a consistent focus on simple, fundamental prospecting and sales activities, any program or cultural change initiative is bound to fail. More than any program workbook, seminar or delivery method, it is the ongoing follow-up, the personal coaching and the manager’s ongoing support that will largely determine the ultimate success of any sales culture transformation and sales training initiative. This has proven to be the winning formula for achieving sustainable results for banks. Now let me explain how we deliver this proven formula. ...

  • To solve these problems, the SEQ and PREDATOR systems introduce a spe- cial sublanguage, called SEQUINfor queries on sequences [Seshadri et al. 1994, 1995; Seshadri 1998]. SEQUIN works on sequences in combination with SQL working on standard relations; query blocks from the two languages can be nested inside each other, with the help of directives for converting data be- tween the blocks.

  • Wall-thinned defects caused by accelerated corrosion due to fluid flow in the inner pipe appear in many structures of the secondary systems in nuclear power plants (NPPs) and are a major factor in degrading the integrity of pipes. Wall-thinned defects need to be managed not only when the NPP is under maintenance but also when the NPP is in normal operation. To this end, a test technique was developed in this study to detect such wall-thinned defects based on the temperature difference on the surface of a hot pipe using infrared (IR) thermography and a cooling device.

  • The notion of Task/Technology Fit (TTF) posits that as the degree of overlap increases between the task domain, and the ways in which the capabilities of an information system (IS) are suited to activities within that domain, performance gains experienced via use of the IS should also increase. This research proposes an expanded TTF model that is applicable to the context of Knowledge Management (KM) and Knowledge Management Systems (KMS).
