This paper describes the design, evaluation, and implementation of a compensation scheme for a measurement voltage transformer (VT) using the hysteresis characteristics of the core. The error of a VT is caused by the primary winding voltage and secondary winding voltage. The latter depends on the secondary current, whereas the former depends on the primary current, which is an aggregate of the ...

 Primary and secondary malignant central nervous system (CNS) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. Glioblastoma multiform (GBM), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced DNA damage repair program that also induces recurrence and resists current chemo- and radi...

background: design of school furniture is one of the contributing factors to back pain among pupils. research has implicated that mismatch between school furniture and body size may be regarded as a causative factor for muculoskeletal disorders amongst pupils. to investigate the fitness between school furniture and pupils this study was designed and implemented in hamadan city, west of iran. me...

Current-fed half bridge converter with bidirectional switches on ac side and a full dc of high frequency transformer is an optimal topology for single stage galvanically isolated ac-dc onboard vehicle charging application. AC are actively commutated to achieve zero current switching (ZCS) using phase shift modulation (SPSM) discontinuous (DCPSM). Furthermore, voltage turn-on (ZVS) achieved swit...

let r be a commutative ring with non-zero identity and m be a unital r-module. then the concept of quasi-secondary submodules of m is introduced and some results concerning this class of submodules is obtained
