Alzheimer's disease (AD) is a neurodegenerative disease leading to a progressive and irreversible loss of mental functions. It is characterized by 3 stages according to the evolution and the severity of the symptoms. This disease is associated with an immune disorder, which appears with significant rise in the inflammatory cytokines and increased production(More)
Peritoneal carcinomatosis is common in advanced pancreatic cancer. Despite current standard treatment, patients with this disease until recently were considered incurable. Cancer gene therapy using oncolytic viruses have generated much interest over the past few years. Here, we investigated a new gene directed enzyme prodrug therapy (GDEPT) approach for an(More)
This paper proposes a novel direct torque control (DTC) strategy for induction motor (IM) drives fed by a fourswitch three-phase inverter (FSTPI). The introduced strategy is based on the emulation of the operation of the conventional sixswitch three-phase inverter (SSTPI). This has been achieved thanks to a suitable combination of the four unbalanced(More)
Currently, road vehicles are more equipped with permanent magnet synchronous motors. Particularly interesting are brushless dc (BLDC) motors, which, due to their inherently sensorless operation, are considered as viable candidates in large-scale production industries such as the automotive one. Within this trend, this paper deals with the synthesis and(More)

Linear machines are currently considered as viable candidates for direct-drive wave and free-piston energy converters. This paper is devoted to an approach based on a magnetic equivalent circuit (MEC), which is also called lumped circuit, dedicated to the modeling and sizing of a tubular linear permanent-magnet synchronous machine (T-LPMSM). The proposed(More)
Pulsewidth modulation (PWM) variable speed drives are increasingly applied in many industrial applications that require superior performance. The carrier-based PWM strategy can be improved by adding different zero sequence signals to the reference sinusoidal phase voltages. This paper presents a comparative evaluation of five carrier-based PWM techniques(More)
