The gain of SVC depends upon the type of reactive power load for optimum performance. As the load and input wind power conditions are variable, the gain setting of SVC needs to be adjusted or tuned. In this paper, an ANN based approach has been used to tune the gained parameters of the SVC controller over a wide range of load characteristics. The multi-layer feedforward ANN tool with the error ...

Case Report A 30-year-old woman was admitted with symptomatic bradycardia 2 weeks after undergoing a third ablation procedure for inappropriate sinus tachycardia (IST) in another centre. A permanent pacemaker was implanted. She re-presented 3 days later with swelling of both arms, neck, and head consistent with superior vena cava (SVC) syndrome. Venography showed bilateral brachiocephalic vein ...

To assess the effectiveness of endovascular stenting for the palliation of superior vena cava (SVC) syndrome, endovascular stent insertion was attempted in 10 patients with symptomatic occlusion of the SVC. All the patients had known malignant disease of the thorax. Eight patients had been treated previously with chemotherapy and radiotherapy (n=5), chemotherapy alone (n=2), or pneumonectomy an...

Single ventricle physiology offers limited options with significant morbidity and mortality. The Glenn shunt is a mid-stage procedure for the Fontan circulation. With persistent left Superior Vena Cava (SVC) and Azygos continuation of the Inferior Vena Cava (IVC) to the SVC, needs the development of bilateral bidirectional Glenn shunts. Fifteen patients underwent Bidirectional Glen shunt proced...

Dynamic reactive power compensation is used to a n increasing extent to improve voltage and reactive power conditions in ac s stems. Additional tasks can also be performed by the i ta t ic Var Compensators (SVC) to increase the transmission capacity as result of employment of SVCs for power oscillation damping. This is of particular importance in the case of weakly coupled power systems. A new ...

Some parasympathetic ganglionic cells are located in the epicardial fat pad between the medial superior vena cava and the aortic root (SVC-Ao fat pad) of the dog. We investigated whether the ganglionic cells in the SVC-Ao fat pad control the right atrial contractile force, sinus cycle length (SCL), and atrioventricular (AV) conduction in the autonomically decentralized heart of the anesthetized...

Due to the continuous increment of the load demand, identification of weaker buses, improvement of voltage profile and power losses in the context of the voltage stability problems has become one of the major concerns for the larger, complex, interconnected power systems. If the voltage profile of the weaker buses is improved, the voltage stability can be improved significantly. Because of the ...

We developed an R toolkit to manage data described by attributes, able to make clusters with a support vector clustering method (SVC). We have implemented an original 2D-grid labeling approach to extract clusters to optimize time processing. In this sense, svc can be seen as an efficient cluster extraction if clusters are separable in a 2-D map. Secondly we showed that this SVC approach using a...
