We present novel schemes for optimal OFDMA bitrate allocation towards video quality maximization in H.264 scalable video coding (SVC)-based 4G wireless systems. We use the rate and quality models for video characterization of the SVC extension of the H.264/AVC and develop the framework for optimal scalable video transmission. Subsequently, we derive the closed form solution of the optimal H.264...

We propose piecewise linear kernel-based support vector clustering (SVC) as a new approach tailored to data-driven robust optimization. By solving a quadratic program, the distributional geometry of massive uncertain data can be effectively captured as a compact convex uncertainty set, which considerably reduces conservatism of robust optimization problems. The induced robust counterpart proble...

This study aimed to develop an automated technique, which is rapid, non-destructive and inexpensive, test for rancidity of nuts. A visible near infrared benchtop hyperspectral camera was used capture images from blanched canarium, unblanched canarium macadamia samples. Support vector machine classification (SVC) PLSR models were developed segregate the pooled spectra nuts predict their peroxide...

Spatially varying coefficient (SVC) models are a type of regression model for spatial data where covariate effects vary over space. If there several covariates, natural question is which covariates have spatially effect and not. We present new variable selection approach Gaussian process-based SVC models. It relies on penalized maximum likelihood estimation (PMLE) allows both with respect to fi...

This paper proposes a reinforcement learning based SVC controller to improve the damping of power systems in the presence of load model parameters uncertainty. The proposed method is trained over a wide range of typical load parameters in order to adapt the gains of the SVC stabilizer. The simulation results show that the tuned gains of the SVC stabilizer using Reinforcement Learning can provid...

The static var compensators SVC are FACTS devices in shunt connection which can be used for power system enhancement. The paper investigates a modern approach for SVC control using fuzzy logic based controller. The simulations and effects of shunt compensation on power system transmission stability are also presented. The SVC modeled in the paper is a TCR-FC type with two components: the thyris...

Oesophageal varices usually develop in the setting of portal hypertension secondary to chronic liver disease. However, superior vena cava (SVC) obstruction can result in 'downhill' varices forming in the upper oesophagus. A case of torrential upper gastrointestinal bleeding from SVC obstruction due to chronic central venous access for home total parenteral nutrition is described. It is suggeste...

Superior vena cava (SVC) aneurysms are a rare entity. The majority of the literature is in the form of case reports. SVC aneurysms are often an incidental finding with iatrogenic, congenital, or idiopathic etiologies. Treatment goals focus on preventing theoretical rupture or thrombus formation. Management options include observation, conservative medical management, surgical excision, and thro...

Superior vena cava (SVC) and inferior vena cava (IVC) pressures were measured serially during laparoscopic cholecystectomy in which the intra-abdominal pressure was maintained at 12 mmHg. The influences of alteration of position from 15 degrees head-down to 15 degrees head-up and of the operative procedure of holding the gallbladder up to the right subphrenic space on SVC and IVC pressures were...
