An efficient light trapping scheme is a key to enhancing the power conversion efficiency (PCE) of thin-film photovoltaic (PV) cells by compensating for the insufficient light absorption. To handle optical components from nano-scale to micro-scale seamlessly, a multi-scale optical simulation is carefully designed in this study and is used to qualitatively analyze the light trapping performances ...

peanuts, an oilseed crop, contain about 46% oil. the peanut shell can be used as fuel or pallets and its dry matter as feedstuff. the whole pods consist of 1-6 kernels. shelling is done at harvest time when the pod moisture content is 5-10%. in this research, a peanut sheller was designed and developed to separate the shell from the pod. the sheller included a hopper, sheller cylinder, concave,...

SYNOPSIS This paper describes some of the latest developments in the use of Emergency Shut Down Systems in process installations both onshore and offshore. The safety implications of these developments are discussed. The effects of common cause failures and human factors with examples of accidents are described. The assessment of systems against HSE Guidelines, industry standards and future int...

Feature analysis, which provides commonality and variability information of a product line, is essential for product line asset development. Moreover, feature binding information (i.e., when and how product features are included to products and delivered to customers) also drives product line component design. Feature binding can be examined from three perspectives: what features are bound (fea...

The nature of CMS construction is heavily constrained by time and budget, evolves with time and is highly distributed. Changes in CMS component design need to be tracked and quickly reflected in the production process. In industry, engineers employ Product Data Management (PDM) systems to control access to documented versions of designs. Workflow management systems (WfMS) [1] are employed to co...
