 Traditional 2-level high-frequency pulse width modulation (PWM) inverters for motor drives have several problems associated with their high frequency switching which produces common-mode voltage and high voltage change (dV/dt) rates to the motor windings. Multilevel inverters solve these problems because their devices can switch at a much lower frequency. Two different multilevel topologies a...

In this paper, the acoustic analysis of noise has been done in automotive cabin at high speed. High-frequency noise sources are applied separately to the roof and floor panels as well as to the windshield of the vehicle, which has been investigated at both the driver's and rear passenger's head. The most important panels that have the most noise emission are specified. In order to analyze high ...

We analyzed the rapid aperiodic X-ray variability of different types of X-ray binaries (black hole candidates, atoll sources, the recently discovered millisecond X-ray pulsar, and Z sources) at their lowest inferred mass accretion rates. At these accretion rates, the power spectra of all sources are dominated by a strong band-limited noise component, which follows a power law with an index roug...

Salmonellais a foodborne zoonotic enteric bacterium able to infect both humans and animals. This study aimed to identify the antimicrobial resistance of Salmonella serovars isolated from human, cattle, and poultry. Moreover, we investigated the probable transmission trends of antibiotic-resistant Salmonella isolates from food animals to human. A total of 242 Salmonella isolates collected from v...

This paper proposes a strategy of a frequency separation-based coordinating power sources within offgrid applications. One of the application is an electric vehicle equipped with two power sources that is ultracapacitor (UC) and a battery, the interaction problem between can be formulated and solved as a linear quadratic Gaussian (LQG) optimal control problem. The two power sources that is batt...
