Title of dissertation: Dynamic Reconfiguration of Network Topology in Optical Networks Pedram J. Fard Doctor of Philosophy, 2007 Dissertation directed by: Professor Steven I. Marcus Department of Electrical and Computer Engineering Dynamic reconfiguration of the logical topology of a network is generally used to adjust the shape of the network to adhere to changes in traffic. In this thesis the...

The obese spontaneously hypertensive rat (SHROB) is a model of metabolic syndrome in which, to our knowledge, vascular function has never been studied. The actions of insulin sensitizers (glitazones) on vascular function have not been analyzed either. Our purpose was to characterize microvascular and macrovascular responses of the SHROB and to study the effects of glitazones on these responses....

Background-—There has been an increasing interest in use of mineralocorticoid receptor antagonists (MRAs) in patients with heart failure with preserved ejection fraction (HFPEF). However, a comprehensive evaluation of MRA effects on left ventricular (LV) structure and function in these patients is lacking. In this meta-analysis, we evaluated the effects of MRAs on LV structure and function amon...

BACKGROUND Mineralocorticoid receptor antagonists (MRAs) are the most underutilized pharmacotherapy for heart failure. Minimal data are available on the barriers to MRA adoption from the perspective of prescribing clinicians. METHODS AND RESULTS A mixed-methods study consisting of a survey (n=50), focus groups (n=39), interviews (n=6) with clinicians at a single US Department of Veterans Affa...

The differential diagnosis between malignancy-related ascites (MRAs) and nonmalignant ascites (NMAs) has remained an essential problem in clinical practice. Our purpose was to determine the diagnostic value of ascitic fluid telomerase activity in discriminating these two categories compared with that of cytological examination. Twenty-five MRAs and 47 NMAs as the control group were enrolled in ...

BACKGROUND There is little data regarding use of mineralocorticoid antagonists (MRAs) for patients reduced LV ejection fraction (LVEF) following acute myocardial infarction (MI). We determined the frequency and temporal trends of MRA use in these patients. METHODS We performed a retrospective review of all cases of acute MI between June 1, 2010 and April 1, 2012. Patients were considered elig...

this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...

this paper presents fuzzy and conventional performance of model reference adaptive control(mrac) to control a dc drive. the aims of this work are achieving better match of motor speed with reference speed, decrease of noises under load changes and disturbances, and increase of system stability. the operation of nonadaptive control and the model reference of fuzzy and conventional adaptive contr...

BACKGROUND Mineralocorticoid receptor antagonists (MRAs) have been shown to be effective in patients with heart failure or myocardial infarction complicated by a reduced ejection fraction. However, the role of MRAs in patients with preserved ejection fraction (PEF) remains to be clarified. We aimed to summarize the evidence for the efficacy of MRAs in patients with either heart failure with PEF...
