The recent developments in electric vehicles (EVs) causes several issues that have not been satisfactorily addressed. One of the foremost problems is charging–discharging processes EV batteries with diverse characteristics. Although a charging station first choice this regard, battery swap (BSS) also suitable alternative solution as it eliminates long waiting periods and degradation due to fast...

To examine the type and effectiveness of various strategies used by Royal Australian Air Force (RAAF) fast jet (FJ) aircrew in self-referral and management of flight-related neck pain, a 6-section, 18-question survey tool was distributed to 86 eligible RAAF aircrew. Selective results from the sections evaluating aircrew demographics, incidence of flight-related neck pain, and the self-referral ...

Ancillary services on the interconnected grid are necessary support for power transmission while maintaining reliable operation and to ensure exact level of quality safety. So many activities operator classified under preview ancillary correct meaning explanation some these distinctions given enough clarity. The basic three with importance that provided by independent producers in a deregulated...

Abstract While ancillary services were initially provided by legacy carriers on short- and medium-haul flights, the emergence of long-haul low-cost has contributed to adoption flights as well. Nevertheless, limited attention been paid specifics how much passengers are willing pay for such services. In this research, we aim assess willingness various show these values differ depending passenger ...

The ground handling operations are used in airports for activities and processing passengers with the help of specially designed vehicles known as support equipment. equipment (GSE) is being parked after serving a flight until next flight. GSE idle duration between flights depending on schedule can be turned into profit source. This paper presenting methodology electrified (EGSE) providing freq...

Wind energy is producing a larger share of power on many utility grids as more wind turbines are installed, providing motivation for wind turbines to provide ancillary services that are necessary for power grid reliability. The ancillary services considered in this paper consist of actively controlling the power output of the wind turbines to track power set-point commands, participate in frequ...

Doubly-fed induction generators (DFIG) constitute some of the larger units met in distributed generation (DG) with significant power control capabilities. These capabilities clearly become more important in modern grids where the aggregation of the individual DG units into larger structures, known as virtual power plant (VPP) concept, is utilized. A special role of DFIGs in the VPP frame is to ...

This article provides an overview of neonatal intensive care unit (NICU) treatment costs. It discusses data sources as well as the methods for measuring costs, contrasting the strengths and weaknesses of alternate approaches. In addition, detailed information on NICU treatment costs is presented from a nationally representative sample of 25 hospitals with NICUs. The sample consists of 3288 very...
