DBSCAN is a well-known algorithm for density-based clustering because it can identify the groups of arbitrary shapes and deal with noisy datasets. However, with the increasing amount of data, DBSCAN algorithm running on a single machine has to face the scalability problem. In this paper, we propose a Map/Reduce-based DBSCAN algorithm called DBSCAN-MR to(More)
To enable a mobile robot to perform intervention or service tasks in a remote environment, the robot should be able to learn the unknown world and execute high level task commands from the operator. In this paper an interactive modeling of man-made environment from a single camera is presented. In this model the geometrical, topological and semantic(More)
A 36-year-old male patient was scheduled to undergo ureteroscopic lithotomy because of left ureteral stone under spinal anesthesia. After receiving a renewed spinal anesthesia with 8 mg tetracaine to compensate for the first attempt (with 10 mg tetracaine), which proved to be a failure, he was soon seized with episodic seizure attacks. Central nervous(More)
BACKGROUND AND AIM The role of computed tomography angiography (CTA) on the management of acute overt obscure gastrointestinal bleeding (OGIB) remains unclear. We designed a study to evaluate the impact of CTA before enteroscopy for acute overt OGIB. METHODS All patients undergoing CTA followed by enteroscopy for acute overt OGIB were enrolled in this(More)
Spinal anesthesia (SA) is frequently used in parturients undergoing Cesarean sections (C/S). The body height (BH) is commonly believed to be one of the factors influencing the spread of SA, especially in patients with extremes of the BH. Recent studies, however, show that the spread of SA is not related to the BH but to the vertebral column length (VL).(More)
