INTRODUCTION Emergency medical technician (EMT) or paramedic (EMTP) certification requirements for flight nurses (FNs) providing on-scene patient care vary. We surveyed those requirements and evaluated the relationships between flight team composition or program location and FN EMS certification. METHODS Telephone survey of all 184 rotor-wing programs responding with a nurse to scenes RESUL...

OBJECTIVE To investigate in a military setting the potential role of intrinsic biomechanical and anthropometric risk factors for, and the incidence of, exertional medial tibial pain (EMTP). METHODS A prospective clinical outcome study in a cohort of 122 men and 36 women at the Australian Defence Force Academy. Each cadet underwent measurements of seven intrinsic variables: hip range of motion...

This paper presents a frequency monitoring system for Korean wide-area power protection based on virtual FDR. The virtual FDR is introduced to enhance the simulation capability of frequency monitoring systems and consists of three parts: modeling, estimation, and simulation. Once a power grid model is obtained in the virtual FDR based on EMTP-RV, the frequency is estimated by DFT filtering and ...

This paper presents a unified approach for efficient modeling and simulation in a multi-tool environment. The motivations are clearly defined and the approach is explained. While this method is applicable to a wide range of tools and applications, it is illustrated with Matlab/Simulink, for control system development, and two EMT simulation tools, EMTP-RV and Hypersim. The sample application is...

With a higher wind power penetration level, the system is facing more challenges in aspects of active balance and frequency regulation. The reserve control enables farm (WF) to retain certain available as reserves, for participating regulation similarly synchronous generators. In this paper, coordinated method WF proposed. By using linear programming approach, proposed allocates each turbine ge...

Energy management in modular type converters constitutes a key aspect of their operational stability. This paper introduces full energy structure for the Extended Overlap-Alternate Arm Converter (EO-AAC) ensuring both equal distribution across all six stacks and maintaining ripple-free DC current during steady state. The performance control against active power step events is validated by detai...

Abstract This paper presents a study on the performance of fourth rail direct current (DC) urban transit affected by an indirect lightning strike. The strike was replicated and represented lightning-induced overvoltage means Rusck model, with sum two Heidler functions as its channel base input, perfect conducting ground. aims to determine whether has any influence regard LRT Kelana Jaya line, D...
