constant leading power factor operationvoltage riseaggregated modeltrunk power systemSUMMARY A voltage rise problem in distribution networks has been discussed as the foremost concern with respect to the spread of large numbers of photovoltaic systems. We focus on the latent ability of the present ...
Although the proposed lead–lag strategy can beat a naïve buy-and-sell strategy, its leading edge is too limited to be satisfied. To this end, enhancement strategies are also designed by integrating the lead–lag strategy in the selected basic alpha-factor strategies. Then, a series of ...
2012; Velu,2015), there is as yet little empirical research on the relationship between innovativeness and firm survival. In general, the existing literature finds that innovation positively affects it (Ugur & Vivarelli
Another serious problem of power electronic converters is drawing reactive power from the source, leading to underutilization of source capacity due to: 1. increased losses in the transmission and distribution, 2. overrated equipment within the AC system, due to larger current drawn for a given rea...
Shenzhen plays a leading role in the national LEE improvement, and the development status of eastern region is better than the central and western regions. Second, the robustness results yield that ETS has significantly aided China to mitigate CO2 emissions and boosted LEE at the national level. ...
Where the coil is the magnetic reluctance is larger leading to a smaller amount of flux. However, since the flux through the total air gap remains approximately constant, the flux at the remainder of the gap increases. The increased flux causes a larger induced voltage when the coil is moved...
leading edge and the horizontal roof area where the airstream speed is at its highest has a negative pressure (negative pressure coefficientCp). When considering the air movement underneath the car body, the restricted airstream flow tends to speed up the air movement thereby producing a slight ...
Effective thermoelectric heat pumping entails high heat pumping power, which is largely reduced to a high power factor (PF = Sα = S2σ) of the material used. TheSis the Seebeck coefficient,αis the Seebeck conductivity, andσis the electrical conductivity (Fig.2a). Developing high ...
(GM), regarding their innovation efforts to develop autonomous delivery vehicles, released in February and October 2018, respectively. Ford’s stock price dropped by 4.7%; GM’s announcement led investors to bump its stock prices by 4.6%. That is, two announcements, both from leading automobile...
Preeclampsia and eclampsia are two of the most common hypertensive disorders of pregnancy (HDPs)1. It is the second leading cause of direct maternal death and is directly responsible for 70,000 maternal deaths annually at the global level2. In low-and middle-income countries (LMICs), 10–15%...
