—A protective relay performance analysis is only feasible when the hypothesis of expected relay operation characteristics as decision rules is established as the knowledge base. This has been meticulously accomplished by soliciting the relay knowledge domain from protection experts who are usually constrained by their experience and expertise. Manually(More)
In modern life, interactions between human beings frequently occur in meetings, where topics are discussed. Semantic knowledge of meetings can be revealed by discovering interaction patterns from these meetings. An existing method mines interaction patterns from meetings using tree structures. However, such a tree-based method may not capture all kinds of(More)
This paper presents a new LiDAR segmentation technique for automatic extraction of building roofs. First, it uses a height threshold, based on the digital elevation model to divide the LiDAR point cloud into 'ground' and 'non-ground' points. Then starting from the maximum LiDAR height, and decreasing the height at each iteration, it looks for coplanar(More)
This paper presents a hierarchical image segmentation algorithm based on the principle of mutual nearest neighbours. Image segmentation remains a great challenge in the computer vision community. To solve this problem, various algorithms have been proposed in the literature. However, most of these algorithms depend heavily on thresholds or parameter(More)
This paper explores the application of the Particle Swarm Optimization (PSO) algorithm for parameter estimation of a Nonlinear Auto-Regressive with Exogeneous Model (NARX) of a Direct Current (DC) motor. The two-step identification step consists of structure selection and parameter estimation. The structure selection process was based on methods from our(More)
Drive systems are prevalent in industrial application of induction motors; while shunt FACTS devices are important to compensate disturbances and increase motor speeding up. In this paper an assessment study between Space Vector PWM (SVM) induction motor drive system and shunt FACTS (such as SVC) installed on terminals of motor is done. It is shown that(More)
