The asymmetric unit of the title complex, [Mn(C(12)H(6)O(4))(H(2)O)](n), contains one Mn(II) ion, one 1,8-naphthalene-dicarboxyl-ate (1,8-NDC) ligand and one water mol-ecule. The Mn(II) ion is six-coordinated within a distorted octa-hedral coordination geometry, in which the equatorial sites are occupied by four carboxyl-ate O atoms from four different 1,8-NDC ligands, while the axial positions...
Addressing the Legacy Costs in an NDC Reform: Conceptualization, Measurement, Financing The paper provides a framework for the conceptualization, definition and estimation of legacy costs that need to be addressed in a reform that transforms an unfunded defined contribution (NDB) scheme into a notional (or non-financial) defined contribution (NDC) scheme. As the new contribution rate is fixed a...
Microgrids are small scale power systems with local resources for generation; consumption and storage, that can operate connected to the main grid or islanded. For the islanding operation of microgrids, two important tasks are to share the load demand and maintain the voltage and frequency stabilities. In order to achieve this goal, a hierarchical control structure can be employed. This researc...
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 exploits 7T/14T bit-enhancing SRAM and onchip voltage/temperature monitoring circuit. 7T/14T bit-enhancing SRAM can reconfigure itself dynamically to a reliable bit-enha...
This work proposes a novel primary frequency control technique with electric vehicles (EV), the combination of inertial emulation and droop control, for isolated systems. Being EV dispersed along the grids, the impacts of possible delayed actions are assessed. Islanded systems have reduced inertia and so load/generation imbalance situations may lead to large frequency deviations. Therefore, thi...
This paper deals with the problem of voltage security in microgrids. In general, voltage security is an issue for power systems, where the lack of reactive power is a concern. For microgrids a complexity is imposed, since frequency and voltage level deviations may take place by the operation of droop-controlled inverters. This paper incorporates the load margin calculation into a microgrid stru...
We demonstrate that the efficiency droop phenomenon in multiple quantum well InGaN/GaN light-emitting diodes (LEDs) may be connected to the current crowding effect. A numerical model of internal quantum efficiency calculation is presented that takes into account nonuniform lateral carrier injection in the active region. Based on this model, we examine the effect of current crowding on the effic...
