The hierarchical control structure was introduced to allow the integration of power electronics based distributed generation into microgrid in a smart and flexible manner. main aim primary controller such is achieve accurate active reactive sharing whereas secondary aims ensure voltage frequency (V/f) stability. Generally, converter level controllers utilize classical nested loop that suffer fr...

Model predictive controller is widely used in industrial plants. Uncertainty is one of the critical issues in real systems. In this paper, the direct adaptive Simplified Model Predictive Control (SMPC) is proposed for unknown or time varying plants with uncertainties. By estimating the plant step response in each sample, the controller is designed and the controller coefficients are directly ca...

OBJECTIVES This study aimed to characterize the clinical profile of familial dilated cardiomyopathy (FDC) in the families of four index patients initially diagnosed with idiopathic dilated cardiomyopathy (IDC) and to provide clinical practice recommendations for physicians dealing with these diseases. BACKGROUND Recent evidence indicates that approximately one-half of patients diagnosed with ...

PURPOSE The aim of this study was to investigate the biological and clinical significance of epidermal growth factor receptor (EGFR) signaling pathway in follicular dendritic cell sarcoma (FDC-S). EXPERIMENTAL DESIGN Expression of EGFR and cognate ligands as well as activation of EGFR signaling components was assessed in clinical samples and in a primary FDC-S short-term culture (referred as ...

Follicular dendritic cell secreted protein (FDC‐SP), has been found to inhibit osteogenic differentiation of human periodontal ligament cells (hPDLCs) in recent studies. Based on these findings, we further investigate its effect on phenotype expression of hPDLCs in the present study, aiming to contribute to a better understanding of the biological functions governing FDC‐SP‐induced hPDLC differ...

NF-kappa B, a 50 kDa/65 kDa (p50/p65) heterodimer, is a ubiquitous transcription factor involved in the positive regulation of various immune genes. The aim of this study was to determine whether NF-kappa B is related to a particular cell type and/or differentiation step during immunopoiesis. Using in situ hybridization on sections from non HIV hyperplastic lymph nodes, we found that the gene o...

in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...

nuclear power reactors are, in nature nonlinear and time varying. these characteristics must be considered, if large power variations occur in their working regime. in this paper a robust optimal gain scheduling controller for regulating the power of a nuclear reactor has been designed and simulated. the proposed controller is capable of regulating power levels in a wide power range (10% to 100...

BACKGROUND In 2009, Brazil was the sole high-burden country to use three drugs [rifampin (R), isoniazid (H) and pyrazinamide (Z)] as the standard treatment for sensitive tuberculosis, with RH in fixed-dose combination (FDC). In December 2009, the country has adopted the FDC four-drug regimen including ethambutol (E). The rationale was the expectation to reduce default and resistance rates, by i...

A widely embraced approach to mitigate the dynamic degradation in low-inertia power systems is mimic generation response using grid-connected inverters restore stiffness of grid. In this article, we seek challenge and advocate for a principled design based on systematic analysis performance trade-offs inverter-based frequency control. With aim, perform qualitative quantitative study comparing e...
