Collaborative recommender systems allow personalization for e-commerce by exploiting similarities and dissimilarities among customers' preferences. We investigate the use of association rule mining as an underlying technology for collaborative recommender systems. Association rules have been used with success in other domains. However, most currently(More)
—In this paper, we propose a novel design of compliant safe joint, which has flexibility when the work load exceeds a pre-defined threshold. The compliance is generated by a spring. We design a special transmission mechanism to convert axial motion into circumferential motion such that the linear compliance can be converted into circular one. When the(More)
— Nowadays, robotic systems make use of compliant joint actuation to provide safe human-robot physical interactions, and in general, to improve the friendliness of the mechanism. However, note that with the introduction of these passive flexible elements, the actuators (which input the control actions) can not explicitly set the driving torque of the(More)
Acquired nonmalignant tracheoesophageal fistula (TEF) is a rare clinical condition with multiple etiologies, although post-intubation injury is the most common cause. TEFs can be fatal if left untreated due to devastating pulmonary complications caused by tracheobronchial contamination and poor nutrition. Herein, we present a case of complete healing of a(More)
