Background: Hot lab is a specially designed room in a nuclear medicine hospital where the radiopharmaceuticals are delivered, stored and prepared for dispensing. 99Mo/99mTc-generator is the major source in the hot lab used for various medical imaging. It is important to maintain a standard for hot lab procedures to optimize the patient care and minimize radiation exposure to all nuclear medicin...

In this paper, the theoretical and experimental performance of the ejector refrigeration cycle is investigated. Making use of EES software, laws of mass and energy conservation as well as the exergy balance equations for a one-dimensional thermodynamic model has been developed and validated using experimental data obtained in the laboratory. It is assumed that mixing takes place at a constant p...

Parameters estimation of dynamic model of synchronous generators is an essential prerequisite for viable and reliable power system operation and offline studies. Advent of phasor measurement units (PMU) and its growing applications in power systems have led to an evolution in the electric power network wide-area monitoring, protection, and control. Alongside, these devices have revealed unprece...

A reliable and accurate diagnosis of inter-turn short circuit faults is a challenging problem in the area of fault diagnosis of electrical machines. The purpose of this challenge is to be more efficient in fault detection and to provide a reliable method with low-cost sensors and simple numerical algorithms which not only detect the occurrence of the fault, but also locate its position in the w...

In recent years, microturbines as one the distributed generation sources have widly used. This paper investigates the control structure of the microturbine and analyzes its performance in grid-connected mode. In this way, first, the mechanical model of the microturbine is presented. Then, the electrical structure of the microturbine, consisting  of permanent magnet synchronous generator (PMSG) ...

In this paper we present an approach to the conversion of the power generated by a seawave power generator integrated in an offshore wind power farm. The article is focused on low power generators that could be used in offshore installations. The generator is a Permanent Magnet (PM) linear generator that generates highly distorted emfs. We propose and compare two possible ways to connect the ge...
