surge is one of the two destructive factors in compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressingsurge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. according to moore-greitzer compressor model, this paper designs an act...
in this paper, photovoltaic (pv) grid-connected inverter which is the core device in pv grid-connected system has been in depth research.an improved predictive current controller has been developed by the authors for single-phase grid-connected voltage source inverters (vsi).based on dsp tms320lf2407a, a 10 kw single-phase grid-connected inverter has been built in this paper.thus is aimed at us...
Introduction: Bleeding disorders are a common problem in daily practice, especially in premenopausal women. In our investigation, we compared the sensitivity and specificity of three different diagnostic methods Trans-vaginal sonography(TVS), saline infusion sonohystrography(SIS) and Hysteroscopy. Methods: It was a cross- sectional study with a study population of ninety-nine women suffering ...
A nonlinear model predictive control (NMPC) algorithm based on neural network is designed for boiler- turbine system. The boiler–turbine system presents a challenging control problem owing to its severe nonlinearity over a wide operation range, tight operating constraints on control move and strong coupling among variables. The nonlinear system is identified by MLP neural network and neur...
Objectives: This research was conducted with the aim of explaining the dysfunctional attitudes of hospitalized cardiovascular patients through dysfunctional metacognitive beliefs. Methods & Materials: This cross-sectional study was conducted in Shariati Hospital in Isfahan, Iran, in 2012. The statistical population was the hospitalized cardiovascular patients of Shariati Hospital in ...
Introduction: Early diagnosis of biliary atresia is very important for better outcome of treatment. Ultrasonography is one of the diagnostic tools for early differentiation of biliary atresia from other causes of neonatal cholestasis. It has been reported that triangular cord sign (TACS) in sonography is a reliable sign for diagnosis of biliary atresia. The aim of this study was to re-assess ...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
In this paper we aim to develop a predictive combustion model for a turbocharged engine in GT-Power software to better simulate engine characteristics and study its behavior under variety of conditions. Experimental data from combustion was initially being used for modelling combustion in software and these data were used for model calibration and result validation. EF7-TC engine was chosen for...
Introduction: This study aimed to compare the cytology results obtained by the conventional smear method with those obtained by the liquid-based method for the diagnosis of palpable breast masses in women referred to the clinic of Shahid Mohammadi Hospital in Bandar Abbas city. Methods: The research method was descriptive–cross-sectional. The research sample was selected based on purposive and ...
