Due to advantages such as high energy density, high power density, rapid charge and discharge, high cyclic-life, and environmentally friendly, flywheel energy storage systems (FESs) are widely used in various fields. However, the performance of FES systems depends on the performance of a high...

Technology innovation or new product development (NPD) is composed of various process elements that require specialized knowledge/know-how needed for the application of fundamental technologies on actual product development. With the widespread use of techniques such as PERT/CPM, a major part of...

This paper presents the work carried out on the chemical reaction, mechanism, role of materials, applications and microstructure of fly ash geopolymer cement. Geopolymeris a type of amorphous alumino-silicate cementitious material. Geopolymer can besynthesized by polycondensation reaction of...

This study proposes a novel parameter optimization method, capable of integrating the neural network and the Taguchi method for parametric analysis of proton exchange membrane fuel cell (PEMFC) performance. Numerous parameters affecting the PEMFC performance are analyzed, such as fuel cell...

This study applies the L9 orthogonal array of the Taguchi method to find out the best hydrogen injection timing, hydrogen-energy-share ratio, and the percentage of exhaust gas circulation (EGR) in a single DI diesel engine. The injection timing is controlled by an electronic control unit (ECU)...

This study designed the processing parameters of the flat-plate collector based on the orthogonal arrays. Processing parameters of a flat-plate collector are the key factors affecting its performance. These parameters include the collector tube material, endothermic plate material, number of...

Castor beans are one of the world's top ten oil crops, with approximately 50% castor oil and 50% castor meal being obtained after a two-stage pressing process (cold and hot pressing). Nevertheless, castor meal still contains a significant amount of residual oil, due to the mechanical limitations...
