Objectives: The existence of a valid scale fear childbirth (FOC) has an effective role in identifying women at risk, so this study was conducted to determine the validation Slade FOC for pregnancy sample Iranian women. Materials and Methods: In cross-sectional study, initially, translated based on forward-backward approach. For sampling among pregnant Anbarabad city, 820 were selected by multis...

Field-oriented control (FOC) has achieved great success in permanent magnet synchronous motor (PMSM) control. For the PMSM drive, FOC allows torque and flux to be controlled separately, which means are decoupled from each other. Since is by speed controller, it can considered that of also other separately. In this paper, we propose a vector using controllers based on proportional-resonant (PR) ...

در این پژوهش ابتدا درباره مشخصات دینامیکی توربین بادی مجهز به ژنراتور القایی دو‏ سو تغذیه بحث می‏شود. dfig نسبت به کمبود ولتاژ پایانه ژنراتور بسیار حساس است. زیرا افت ولتاژ عمیق باعث القای ولتاژ‏های ضد محرکه‏ی بزرگ در روتور می‏شود که این امر منجر به عبور جریان گذرای شدید از روتور و افزایش ولتاژ لینک dc در مبدل قدرت و در نتیجه آسیب دیدن مبدل الکترونیک قدرت می‏گردد. ولتاژهای نیروی ضد محرکه‏ی القا...

Abstract Bachground and objectives: The ability of adherence to the surface of host cell is very critical in the colonization of microbial pathogens. It has been revealed that E. coli strains that infect urinary tracts have different fimbrea such as I, S, FIC, Dr, and fimbrial adhesions. Material and Methods: In this study, 363 urine samples were obtained from patients with urinary tract infect...

This study introduces a field oriented controlled (FOC) induction machine based flywheel energy storage (FES) system fed from a 20kHz ac link and Pulse Density Modulated (PDM) Converter. The feasibilty of FES system is investigated both in software and hardware and is demonstrated succesfully in both cases. The investigated system offers a good potential as a temporary energy storage system for...

We describe the Fiber-on-Chip (FoC) approach to verification of digital signal processing (DSP) circuits, where models a fiber-optic communication system are implemented in same hardware as DSP under test. The can enable cost-effective long-term evaluations without need for complex optical-electronic testbeds with high-speed interfaces, shortening time and enabling deep bit-error rate evaluatio...

Fusarium oxysporium f. sp. cubense (Foc) race is an archetypally soil-born fungus causing chief fiscal damage to farmers growing banana plants. Supervising Foc attained by the habit of chemical fungicides which undesirably harm soil fertility. Our investigations intended activate aptitude Trichoderma strains for activation PGPR and IIR. The accretion defence enzymes such as Polyphenol Oxidase (...

The aim of this paper is to investigate the impact of the upcoming Galileo system on GNSS tomography. The area covered by our tomography model is limited to the Austrian territory. The GPS and GLONASS data of 12 sites in different environments are analysed with respect to its quality and impact on the atmospheric tomography approach. We show how additional Galileo observations help to close the...
