    Abstract: This paper explores further the capability and versatility of Barlase in establishing deeper understanding of the behaviour of an emitter in a laser bar. The interactions between an emitter and the substrate upon which it is mounted are important in learning more about the degradation process that occurs in lasers. It is well known that various fac...

    Abstract: Total complaints related to voltage sags are about 80 % of all the complaints due to power quality transients. AC Contactors are designed to disconnect the load or circuit they control when the main power supply is intentionally interrupted. The sensitivity of AC coil contactors to the applied voltage is thus a potentially weak link in industrial p... Show More

    Abstract: This paper presents some conclusions of a larger review article which regards possibilities for speed adjustment at synchronous reluctance motors. In the first part there are detailed the command variants by modifying the supply voltage and frequency (open loop control and vectorial control). There are reviewed the variants with and without positio... Show More

    Abstract: This study aimed at identifying design features that can be incorporated in buildings to make them energy efficient. Energy audit and analysis is necessary to increase building energy efficiency. Three methods to increase energy efficiency were selected based on installation cost: the first method of low cost is replacing T-8 fluorescent lamps (FL... Show More
  • Objective Image Quality Evaluation Model for JPEG2000 Coded Images Based on Edge Information Measures

    Abstract: In this paper, a no-reference objective quality assessment model is proposed for JPEG2000 coded images. It is well established that human visual system is very sensitive to edge information; consequently we believe that perceptual artifacts of any image are strongly dependent on local features such as edge and non-edge areas. Therefore edge and non... Show More
