Original scientific paper This paper presents a heuristic algorithm PSO based simultaneous coordinated tuning of the SVC damping controller and power system stabilizer (PSS) in a two machine three bus power system. The coordinated tuning of PSS and SVC damping controller is converted to an optimization problem which is solved by particle swarm optimization (PSO) technique. The parameters like r...

We present an asymptomatic patient with a history of prolonged hemodialysis through a right internal jugular vein catheter who was diagnosed with superior vena cava (SVC) obstruction on 99mTechnetium-diethylenetriaminepentaacetic acid renal transplant scintigraphy. During the angiographic phase, an unusual vascular filling pattern was detected on the anterior view of the abdomen. Angioscintigra...

In this paper, we propose a new approach to detect activated time series in functional MRI using support vector clustering (SVC). We extract Fourier coefficients as the features of fMRI time series and cluster these features by SVC. In SVC, these features are mapped from their original feature space to a very high dimensional kernel space. By finding a compact sphere that encloses the mapped fe...

This paper discusses a new technique for controlling SVCs (Fixed Capacitor–Thyristor Controlled Reactor) in power systems with the aim of canceling the reactive current component of the load. A complete model of the SVC with its control circuit is set up and simulated in the EMTDC program. The generated harmonics from the proposed SVC controller are considered to design simple tuned filters to ...

The scalable extension to the H.264/AVC has been established as a Scalable Video Coding (SVC) standard, and JPEG2000 is a state of the act still image coding standard. SVC is based on the Discrete Cosine Transform (DCT) and JPEG2000 is based on Discrete Wavelet Transform (DWT). Despite the DWT has been successfully employed in still image coding, the latest video coding standard keeps on ultili...

Myxomas are the most common benign cardiac tumors. Myxomas are more common in the left heart chamber than the right side chamber. An extracardiac origin presenting as a right atrial mass is very rare. We present a case of myxoma originating in the superior vena cava (SVC) in a 24-year-old man, who underwent surgical resection. Preoperative two-dimensional echocardiography demonstrated a mass in...

A 41-year-old man was brought to the ED after a motor vehicle crash. On presentation, he demonstrated symptoms compatible with superior vena cava (SVC) syndrome, including extreme dyspnea, face and neck cyanosis and facial swelling. A chest tube was inserted and drained large amounts of sanguineous fluid. An exploratory thoracotomy revealed an extensive tumour encasing the SVC and the hilum. Bi...

INTRODUCTION The superior vena cava (SVC) can act as an origin of atrial fibrillation (AF). The complex structure and special conductive properties of the SVC can result in complicated atrial tachycardia (AT), atrial flutter, or AF. SYMPTOMS AND CLINICAL FINDINGS We report a case of the clinical observation of various kinds of AT and AF in 1 patient. Electrophysiological (EP) studies confirme...

The paper presents some considerations regarding the structure and behaviour of the static var compensator (SVC). Thus, starting from a structure of the compensator it determinates the fundamental impedance of the SVC and it analyses the dependence of the impedance v.s. the components elements (C, R, Lc). Also, it has been realised and the analyses regarding the overvoltages which can appears o...

Measurements of dynamic force-length behavior of maximally activated strips of smooth muscle during oscillatory length changes show that force decreases well below the isometric force during the shortening phase of the oscillation. The magnitude of the decrease depends on the rate of shortening; for slower shortening, the decrease is smaller and force is larger. Modeling of expiratory flow, bas...
