Since the introduction of transesophageal echocar-diography (TEE) to the operating room in the early 1980s, 1-4 its effectiveness as a clinical monitor to assist in the hemodynamic management of patients during general anesthesia and its reliability to make intraoperative diagnoses during cardiac operations has been well established. 5-26 In recognition of(More)
This paper discusses how to generate mobile robots' behaviors using genetic algorithms, GA. The behaviors are built using state machines implemented in a programmable logic device, an FPGA, and they are encoded in such a way that a state machine architecture executes them, controlling the overall operation of a small mobile robot. The behaviors generated by(More)
Research in peer-to-peer file sharing systems has focused on tackling the design constraints encountered in distributed systems, while little attention has been devoted to the user experience: these systems always assume the user knows the public key of the file they are searching. Yet average users rarely even apprehend that file public keys exist. File(More)
This paper discusses an interview-based study conducted to explore why people like particular pages on Facebook. We analyze how the different relationships that people have with their Facebook likes could affect the design of intelligent interactive systems. Specifically, we examine how the likes of a user's friends can be used to gather information from(More)
The friend list of many social network users can be very large. This creates challenges when users seek to direct their social interactions to friends that share a particular interest. We present a self-organizing online tool that by incorporating ideas from user modeling and data visualization allows a person to quickly identify which friends best match a(More)
— Disc Jokeys (DJs) generally mix music in a confined isolated space. This can make the DJ have depression sentiments and it can also difficult the DJ's understanding of his public. We present Enchantment Under The Sea: a new intelligent environment that allows the disc jokey to roam freely, interact directly with his audience, receive informative feedback(More)
A lthough both disciplines have cooperated for many years, cardiovascular anesthesiology and echocardiography have recently grown and merged in part. Intraoperative echocardiography has demonstrated its usefulness in many aspects of cardiovascular surgery, including valvular repair and replacement, myocardial function, aortic aneurysm repair , congenital(More)
