Microgrids are becoming increasingly attractive to consumers and as such in the future, a great number of them will be installed at consumer's sites. In this situation, conventional distribution networks that accept distributed generation connections may face serious difficulty when its control and protection functions become more complicated. This incurs a(More)
We present an approach for accurate localization of the neck of intracranial aneurysms and quantification of their geometry that is useful for their treatment through endovascular embolization. In particular, we first obtain a vessel segmenta-tion using a topology-preserving level set method and extract the surface of the segmented vessel. We then separate(More)
The objective of this study is to minimize the classification cost using Support Vector Machines (SVMs) Classifier with a double hinge loss. Such binary classifiers have the option to reject observations when the cost of rejection is lower than that of misclassification. To train this classifier, the standard SVM optimization problem was modified by(More)
This paper presents an efficient maximum power point tracking (MPPT) controller for a standalone photovoltaic (PV) generation system. To achieve an efficient MPPT controller, a new boost converter design and an improved MPPT algorithm are incorporated. In the proposed boost converter design, a passive regenerative snubber circuit is included to absorb the(More)
This paper presents a new intelligent control scheme which utilizes particle swarm optimization (PSO) for off-line tuning of proportional-integral-derivative (PID) controller for the twin rotor multi-input multi-output system (TRMS). The control objective is to make the beam of the TRMS move quickly and accurately to the desired attitudes. The TRMS exhibits(More)
