Abstract Particle swarm optimization algorithm (PSO) is suggested to discover fractional order PID (FOPID) controller optimal variables for a better performance of induction motor. This PSO designed handle multiple issues, due its ease application. A Closed Loop Quadratic Boost Converter Multilevel Inverter Fed Induction Motor (QBCMLIIM) system simulated earn reduced switching losses and THD by...

Pressure-gain combustion has gained attention for airbreathing ramjet engine applications owing to its better thermodynamic efficiency and fuel consumption rate. In contrast with traditional detonation induced by a single wedge, the present study considers oblique shock interactions attached double wedges in hypersonic combustible flow. The temperature/pressure increases sharply across interact...

considering great medicinal value of hyssopus officinalis l. and possibility of its mass production through in vitro culture, two individual experiments was conducted. effect of various concentrations (0, 2.2, 4.4 and 11 µmol) of tdz and bap in combination with 1 µmol of iaa on direct regeneration from nodal explants were assessed. significant difference between treatments was observed (p≤ 0.01...

Design and Methods. In a multicenter trial 33 patients aged 61-65 years with de novo or secondary AML were treated with double induction therapy including high dose mitoxantrone, etoposide and ara-C (MAV) in the first course and m-amsacrine together with high dose ara-C (MAMAC) in the second course. Treatment results were compared to those in 39 AML patients older than 65 years receiving conven...

We have generated mice lacking synaptogyrin I and synaptophysin I to explore the functions of these abundant tyrosine-phosphorylated proteins of synaptic vesicles. Single and double knockout mice were alive and fertile without significant morphological or biochemical changes. Electrophysiological recordings in the hippocampal CA1 region revealed that short-term and long-term synaptic plasticity...

-In this paper we present a new control structure to extract the maximum power of a wind energy conversion system based on the double fed induction generator (DFIG). The proposed algorithm combines the nonlinear Backstepping approach and the field orientation scheme applied to control the rotor side converter (RSC) and the grid side converter (GSC) of the DFIG. The proposed strategy is asymptot...

Pulsed field gel electrophoresis was used to examine the influence of chromatin structure on the induction of DNA double strand breaks by gamma-irradiation in CHO-WBL cells, nuclei, and a series of protein-depleted chromatin substrates. We developed a method to isolate intact nuclei in agarose plugs that avoids DNA shearing and nucleolytic degradation during sample preparation, and facilitates ...

The observed induction time from an infection to event of interest is often double-interval-censored and moreover, prevented being by the clearance (a competing risk). Double-interval-censoring presence risks complicate statistical analysis extremely are therefore usually ignored in infectious disease studies. Often, times at which events detected used as a proxy for exact interpretation has be...

Between 1990 and 1996, we conducted a randomized trial in adults with newly diagnosed acute myeloid leukemia (AML) in order to compare relapse-free interval (RFI) after double induction (arm B), timed-sequential induction (arm C), or control "3 + 7" induction (arm A). Patients achieving complete remission (CR) after induction +/- salvage received the same consolidation chemotherapy, which inclu...
