In this paper, a new ultrahigh step-up converter composed of two stages boost converter, a switched capacitor unit and coupled inductor is proposed.Secondary winding of the coupled inductor has been merged with the switched capacitor and leakage energy of the coupled inductor recycles through the output side.The structure contains two power switche
The article presents the results of analytical numerical calculations of the cruciform foun- dations under the uniformly distributed load.The distributions of the stresses and displace- ments in active zone of the cross-shaped foundations are featured.The comparison of De-Puffing Wand experi- mental and analytical settlements of complex form founda
The purpose of this study is to Swabs evaluate the acoustic performance of lightweight concrete with ethylene vinyl acetate copolymer (EVA) residues to reduce impact noise on floors.Three types of concrete with three different mix proportions were evaluated.The method adopted includes the characterization of water absorption, voids and density of t
Conducting evaluation and research with community coalitions involved in health equity initiatives is inherently complex.In this paper we provide a review and synthesis of the empirical literature on the evaluation of equity-focused community coalitions.We explore issues, challenges, and barriers experienced by evaluators, as well as techniques and
