Because the electrical installations are nowadays a lot of options and variants, it is necessary to evaluate these complex installation process from several perspectives and objectively. Due to the complexity of evaluation of electrical installation is design a methodology that uses multi-criteria analysis MCA.

We introduce a method to enhance the luminescence of GaN-based LEDs by combining the direct heteroepitaxy laterally overgrowth (DHELO) technique with selective wet etching process. The epitaxial overgrowth of GaN layers on sapphire substrate with SiO2 micro-rods array exhibited a reduced dislocation density and improved the crystal quality. The EL intensity of LEDs with SiO2 micro-rods array wa...

Microgrids have become increasingly popular in recent years due to technological improvements, growing recognition of their benefits, and diminishing costs. By clustering distributed energy resources, microgrids can effectively integrate renewable resources distribution networks satisfy end-user demands, thus playing a critical role transforming the existing power grid future smart grid. There ...

The chance to influence the lives of a million children comes once in a generation. With the partnership between the BBC and several technology companies, a small device, the BBC micro:bit will be given to a million children in the UK in 2016. Moreover, using the micro:bit will be part of the curriculum. This demo describes the BBC micro:bit together with its software platform, based on Microso...

The trend to miniaturization cannot be overseen. The use of very small electronic and electro-optical components in a variety of consumer and investment goods is leading to an increasing demand for small-scale servo actuators for micro assembly applications in production equipment. The previous generation of micro gears and micro actuators was not suited to this type of application, because of ...

background: l-menthol [(1r,3r,4s)-(-)-menthol] is a flavoring that is the main component of mint herb essential oils, especially of the mentha piperita and mentha arvensis species. its low solubility in aqueous systems makes precise formulation necessary in the final products. of the methods available for fabrication of nanoparticles for use in pharmaceuticals, electrospraying is easy and requi...

To improve the comprehensive benefits of CCHP system, this paper proposes a bi-level optimal configuration model system based on improved FCM clustering algorithm. Firstly, traditional algorithm, entropy method is used to introduce PFS index and Vp in weighted form achieve evaluation effect. The effectiveness algorithm verified by analyzing process load meteorological data using Then best clust...
