Molybdenum cofactor deficiency (MOCOD) is a rare inherited metabolic disorder resulting in the combined deficiency of aldehyde oxidase (AO, EC 1.2.3.1), xanthine dehydrogenase (XDH, EC 1.1.1.204), and sulfite oxidase (SUOX, EC 1.8.3.1). The majority of patients typically present soon after birth with intractable seizures, developmental delay and lens(More)
BACKGROUND Decision analysis in hospital-based settings is becoming more common place. The application of modeling and simulation approaches has likewise become more prevalent in order to support decision analytics. With respect to clinical decision making at the level of the patient, modeling and simulation approaches have been used to study and forecast(More)
Switched reluctance machines have emerged as an important technology in industrial automation; they represent a real alternative to conventional variable speed drives in many applications. This paper reviews the technology status and trends in switched reluctance machines. It covers the various aspects of modeling, design, simulation, analysis, and control.(More)
Drug utilization in the inpatient setting can provide a mechanism to assess drug prescribing trends, efficiency, and cost-effectiveness of hospital formularies and examine subpopulations for which prescribing habits may be different. Such data can be used to correlate trends with time-dependent or seasonal changes in clinical event rates or the introduction(More)
In aircraft electric motor driven fuel delivery system, the motor must be characterized by high power density, reliability, less size, less weight and high speed. The high speed operation, fault tolerance, high power density makes switched reluctance motor an ideal candidate for high speed aerospace applications. This paper investigates the application(More)
This paper presents some aspects of soft magnetic composite (SMC) material application in switched reluctance motor (SRM). The presented stator core of the SRM is made of two types of material, the classical laminated silicon steel sheet and the soft magnetic composite material. First, the stator core made of laminated steel has been analyzed. The next step(More)
Soft Magnetic Composite (SMC) material is formed by surface-insulated iron powder particles, generating unique properties like magnetic and thermal isotropy, and very low eddy current loss. This paper delineates the key aspects of soft magnetic composite (SMC) material application in Switched Reluctance Motor(SRM), through dynamic magnetic characterization(More)
In aircraft electric motor drive fuel delivery system, the motor must be characterized by high power density, reliability, less size, less weight and high speed [1]. The high speed operation, fault tolerance, high power density makes switched reluctance motor an ideal candidate for high speed aerospace applications. This paper investigates the application(More)
This Paper presents the function of Single Phase Matrix converter as a Dual Converter (Bi-directional speed control of DC drive), Rectifier and also as Inverter. Sinusoidal Pulse Width Modulation (SPWM) technique is used to generate control pulses for the Matrix Converter switches to produce output. The switching sequences for the Matrix Converter to(More)
This paper addresses the need for the exploration of utilization of maintenance free electric machines in non-conventional energy conversion systems. In stand alone wind energy conversion system meant for rural areas, cost effective and maintenance free electric machine as generator is envisaged to be an integral part of the system. The suitability of(More)
