The background of this research is to understand the operation process, which main goal developing process model. This model often used for operator training, design, safety system analysis, or control design. dynamic milk cooling from 36˚C 4˚C using chilled water available at 2˚C was performed. Chilled maintained a constant temperature by refrigerant unit. being investigated Packo brand tank b...
With the growing impact of power regulators, machines, and other electronic devices on quality utility electric service, harmonics has recently emerged as a major research topic in area energy consumption. In this work, fuzzy intelligent inductor–capacitor–inductor hybrid filter is designed to reduce distribution line. The shunt active passive design consideration have been improved. Since natu...
The paper deals with the development of an experimental benchmark mechatronic system that was employed in control courses taught at our university. first part introduces its mechanical design, installed instrumentation and software environment. Methodology use terms curriculum follows, highlighting particular problems students can solve during their classes. last section summarises observations...
Two controls of the phosphate (PHO) regulon require sensor proteins that are protein kinases that phosphorylate the regulator, PhoB, which in turn activates transcription only when phosphorylated. Pi control requires the Pi sensor PhoR; the other control is Pi independent and requires the sensor CreC (formerly called PhoM). Here we describe an additional control of the PHO regulon which is Pi i...
BACKGROUND Irritable bowel syndrome (IBS) is a common functional bowel disorder. The post-infectious IBS (PI-IBS) occurs in IBS patients with a history of intestinal infection preceding the onset of symptoms. However, the underlying cause of PI-IBS is not fully understood, and the purpose of this study was to investigate the immune regulatory mechanism of PI-IBS. METHODS Participants enrolled...
OBJECTIVES The aim of this study is to investigate the role of platelet-derived growth factor (PDGF) in the pathogenesis of sinonasal polyps. METHODS Study group (groups 1-3) consisted of nasal polyp samples of patients with sinonasal polyps and the control group consisted of inferior turbinate samples of patients without nasal polyp. In group 1, 14 specimens from ethmoid sinus; in group 2, 1...
This paper addresses the design procedure of a fuzzy logic-based adaptive approach for DFIGs to enhance automatic generation control (AGC) capabilities and provide better dynamic responses in multi-area power systems. In doing so, a proportional-integral (PI) controller is employed in DFIG structure to control the governor speed of wind turbine. At the first stage, the adjustable parameters of ...
This study presents the real time hybrid controller implementation for a Switched Reluctance motor Drive. The developed hybrid control law consists of Proportional Integral (PI) controller at steady state, PI-type fuzzy logic controller (FLC) at transient state and a simple logic controller between steady and transient states to achieve desired performance at various operating conditions under ...
This paper proposed a new voltage control strategy for an islanded Microgrid (MG). A MG is consists of several Distributed Generation (DG) and local loads and controllers which it should be capable to operates in both connected and disconnected mode from main grid. Often there are some uncertainties in load and system parameters in isolated mode hence, robust control of electrical quantities is...
OBJECTIVE To demonstrate the effect of hypokinesia (HK) and post-HK on phosphate (Pi) imbalance and use of Pi with different Pi imbalance and different Pi consumption: were measured Pi balance, plasma Pi level and Pi loss during HK. METHODS Experiments were conducted during the pre-experimental period of 30 days, and the HK period of 364-days and post-HK period of 30-days. Forty healthy male ...
