Railways as a dimension of transportation infrastructure has been widely welcomed in developed and developing industrial countries because of the ability to carry heavy loads over long distances, more safety, less depreciation, less cost, less pollution, etc. Therefore, knowledge of the dynamic behavior of the railway is essential for designers and builders. It is very important to study the vi...

This paper investigates for transformation of the distorted current low order higher harmonic self-generation phenomenon tested inductive transformers. The influence main component and 3rd primary on RMS values 5th, 7th 9th self-generated harmonics is analyzed. research indicate that change value causes variation lower generated in to secondary current. Therefore, this a challenging which have ...

We develop a model of ̄rm size in which ̄rms are unable to access as many consumers as they want. Newly arrived consumers match randomly with ̄rms. Subsequently, consumers must pay search costs to be able to switch ̄rms. This cost promotes an inertial tendency for consumers to remain with the ̄rm they currently buy from. Consequently, established ̄rms enjoy a proprietary relationship with respe...

Rhabdomyosarcoma (RMS) is an aggressive family of soft tissue tumors that most commonly manifests in children. RMS variants express several skeletal muscle markers, suggesting myogenic stem or progenitor cell origin of RMS. In this review, the roles of both recently identified and well-established microRNAs in RMS are discussed and summarized in a succinct, tabulated format. Additionally, the s...

Several input-output gains of linear periodic systems are deened, in particular, G(` 2 ; ` 2)| the worst-casè 2 norm of the output over all inputs of unit`2 norm|and G(RMS; RMS)|the worst-case RMS value of the output over all inputs of unit RMS value. It is proved for linear periodically time-varying (LPTV) systems that these two gains are equal, a known fact for LTI systems. In addition, the r...

Electromyography is a commonly used method to determine relative effort and neuromuscular drive to skeletal muscle. A limitation of the interpretation of EMG within the literature is the many methods used to determine the intensity of muscle activation. In the current study, ten healthy young adults performed a level walking task while EMG was recorded from the tibialis anterior, medial gastroc...

This letter proposes a control strategy for reducing ripple current in DC-link capacitor of single-phase uninterruptible power supplies (UPS). The proposed method aims to reduce the by difference between input and output instantaneous power. waveform should satisfy harmonic regulation be as close possible load current. Therefore, an auxiliary buck chopper was added compensate capacitor. Experim...
