For islanded microgrids, droop-based control concepts have been developed both in single and three-phase variants. The three-phase controllers often assume a balanced network; hence, unbalance sharing and/or mitigation remains a challenging issue. Therefore, in this paper, unbalance is considered in a three-phase islanded microgrid in which the distributed generation (DG) units are operated by ...
BACKGROUND AND PURPOSE Pretreatment prediction of patients with nasopharyngeal carcinoma who will fail conventional treatment would potentially allow these patients to undergo more intensive treatment or closer posttreatment monitoring. The aim of the study was to determine the ability of pretreatment DWI to predict local failure in patients with nasopharyngeal carcinoma based on long-term clin...
This letter proposes a general decentralized control of single phase cascaded inverters-power factor angle droop control. Compared to the existing strategies, it has following attractive benefits: 1) is suitable for both grid-connected and islanded modes; 2) Seamless transition between different modes can be obtained; 3) stability condition in mode independent transmission line impedance; 4) su...
This paper presents a resilient cache memory for dynamic variation tolerance in a 40-nm CMOS. The cache can perform sustained operations under a large-amplitude voltage droop. To realize sustained operation, the resilient cache exploit 7T/14T bit-enhancing SRAM and on-chip voltage/temperature monitoring circuit. 7T/14T bitenhancing SRAM can reconfigure itself dynamically to a reliable bit-enhan...
BACKGROUND AND PURPOSE The role of advanced MR imaging techniques in demonstrating the microarchitectural changes in osteoporosis has been recently investigated. Our aim was to determine the role of quantitative and diffusion MR imaging in the diagnosis of osteoporosis compared with dual-energy x-ray absorptiometry (DEXA). MATERIALS AND METHODS Fifty-one subjects underwent both DEXA and conve...
