This investigation deals with a mathematical model for a distribution transformer including saturation effect. To this end, the equations related to a three phase transformer are specified and the effect of an inter-turn fault is included. Naturally by applying an inter-turn fault the inductance and resistance matrix will change. Thus, unknown quantities of inductances and resistances for compl...
Prostate cancer (PCa) is the most common non-skin cancer among men. Currently available diagnostic tests for PCa are inadequate in terms of low specificity and poor sensitivity. microRNAs offer a hope to overcome these drawbacks by virtue of their cancer specific expression and high stability. They can readily be detected and quantified in frozen and as well as formalin-fixed paraffin-embedded ...
Circulating microRNAs (miRNAs) have been detected in various types of cancer and have been proposed as novel biomarkers for diagnosis and treatment. Until recently, however, no studies had comprehensively examined circulating miRNAs in oral cancer. The current study used an ultra-sensitive genome-wide miRNA array to investigate changes in circulating miRNAs in plasma from five patients with ora...
This paper describes a novel analytical methodology for modelling winding copper losses as result of circulating currents (CC) in permanent magnet synchronous machines (PMSM). CCs are important to be considered at an early design stage especially high frequency and performance where sub-optimal choices can lead significant alternating current (AC) losses. Nowadays mainly FEM method is used prec...
