BACKGROUND Increased inactivation of nitric oxide by oxygen free radicals contributes to endothelial dysfunction in patients with coronary artery disease (CAD). We therefore determined the activity of extracellular superoxide dismutase (EC-SOD), the major antioxidant enzyme system of the vessel wall, and its relation to flow-dependent, endothelium-mediated dilation (FDD) in patients with CAD. ...

A robotized manufacturing cell of pre-fabricated GRC (Glass Reinforced Cement) panels for construction industry has been developed by DISAM for the Spanish construction company Dragados, S.A.The main contribution of the developed system is the automatic program~ ming and control of the whole plan. The architect's 3D-drawing of the building facade done on a CAD system serves as input. From the C...

Running a large and complex virtual environment may require certain computational services to be implemented in a distributed manner, especially those that are relatively less time-critical, considering the network delay. An important question, therefore, is the criteria for migrating computational processes oo the main graphics rendering workstation to optimize the performance per cost in the ...

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...

Angiotensin II is the major effector molecule of renin-angiotensin system; its production can be conveniently interrupted by angiotensin-converting enzyme (ACE). Typical plasma levels of ACE accompany the I/D polymorphism; however, a controversy exists as to whether the DD genotype of the ACE polymorphism affects the risk for the development of coronary artery disease (CAD) and to what extent t...

background: the existing evidence suggests that plasma adiponectin concentrations can be indicative of the presence and severity of coronary artery disease (cad). however, the results of the studies conducted hitherto on this subject are inconsistent. we sought to investigate the possible correlation between plasma adiponectin levels and the presence and severity of cad in patients undergoing n...

OBJECTIVES Inflammation and activation of immune system cells play an important role in the pathogenesis of atherosclerosis. This study analyzes the white blood count, including neutrophils, eosinophils, lymphocytes, monocytes and basophils, of patients with chronic coronary artery disease (CAD) and acute myocardial infarction (AMI). METHODS The white blood cell count was analyzed in 232 pati...

Reverse Engineering is concerned with the problem of creating CAD models of real objects by measuring point data from their surfaces. Current solutions either require manual interaction or expect the nature of the objects to be known. We believe that in order to create a fully automatic system for RE of unknown objects the software that creates the CAD-model should be able to control the operat...

this paper presents a cooperative control which is applied to the secondary control of a microgrid controlled via a multi-agent scheme. balancing power that leads to voltage and frequency stability in a microgrid is essential. the voltage and frequency regulations are limiting within the specified limits and conveying them to their nominal values. limiting and conveying the voltage and frequenc...
