Small and micro enterprises have a decreasing participation in vocational education and training. There is a real need to engage them in developing a positive attitude towards training. The BOOST (Business perfOrmance imprOvement through individual employee Skills Training) project will integrate outcomes from two previous projects (BECOME and ROLE), in order to develop associated methodologies...

This paper deals with mainly the profoundly deaf people who are beginning to learn the British Sign Language (BSL) as their first language for communication. These beginners could be children, teenagers or even adults who have hearing problems. There are already quite a few BSL learning websites and Lip Reading software available on the market. However, there is no such software that associates...

in this paper the maximum power point tracking (mppt) algorithms for wind energy systems arereviewed. as the amounts of power produced in wind power plants is changing due to theinstantaneous changing nature of the wind, it is desirable to determine the one optimal generatorspeed that ensures maximum energy yield. thus, it is important to include a controller that cantrack the maximum peak rega...

This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...

We report our results on the influence of the dipole moment of small molecules anchored to the surface of CdSe nanocrystals, over the interfacial charge recombination dynamics in CdSe/P3HT (P3HT : poly-3-hexylthiophene). The polarizability of the CdSe/P3HT interface is key to achieving efficient charge separation and slow back electron transfer, two of the most important processes to boost the ...

AlN passivation layers grown by atomic layer epitaxy have been implemented to passivate the surface of AlGaN/GaN high electron mobility transistors (HEMTs). These layers suppress surface charge trapping effects, such as current collapse, reduction of maximum drain current, and increase of dynamic on resistance. Each passivation scheme is characterized using pulsed I-V measurements, a novel on-w...

BACKGROUND For breast cancer patients who require electron boost energies between 6 and 9 MeV, an energy degraders (ED) in the 9 MeV beamline was specially designed and manufactured to increase the skin dose of 6 MeV and to reduce the penetration depth of 9 MeV beams. METHODS We used Monte Carlo (MC) techniques as a guide in the design of ED for use with linear accelerators. In order to satis...

the field of vaccinology provides excellent promises to control different infectious and non-infectious diseases. genetic immunization as a new tool in this area by using naked dna has been shown to induce humoral as well as cellular immune responses with high efficiency. this demonstrates the enormous potential of this strategy for vaccination purposes. dna vaccines have been widely used to de...
