This paper demonstrates magnetic three-degree-of-freedom (3-DOF) closed-loop position and 2-DOF open-loop orientation control of a mockup magnetic capsule endoscope in fluid with a single permanent magnet positioned by a commercial 6-DOF robotic manipulator, using feedback of only the 3-DOF capsule position measured by a localization system, with application in capsule endoscopy of a fluid-dist...

We characterize stochastically stable states in noisy asynchronous repeated games. Players repeatedly play a 2 × 2 coordination game with random pairwise matching. The games are noisy because the players may make mistakes when choosing their actions and are asynchronous because only one player can move in each period. We show that if there is a sufficiently patient player, the efficient state c...

The project Hé(和, harmony) is a sound installation that enables a user to play music by writing calligraphy. We developed a system where calligraphic symbols can be detected and converted to a sound composed of pitch, pitch length, and volume though MIDI and serial communication. The Hé sound installation involves a micro-controller, photocells, and multiplexers. A DC motor controls the speed o...

Introduction The increasing speed of serial data transmission systems places greater importance on measuring jitter with higher accuracy. Serial data standards normally require operation at an expected error rate of 10. While this represents only one bit error every 2.3 hours at 100 Mb/s, it translates to one error every 4 minutes at 3Gb/s. It is, therefore, important to understand the characte...

Research about Group Support Systems and the design of these group support technologies is mainly based on western culture and takes little explicit account of other cultures. While the research reveals promising results on the effectiveness of these technologies, the research results and the technologies themselves may be less effective when applied directly to different cultures or cross-cult...

In this paper we present a portable, battery operated 3D magnetic microsystem (magnetodosimeter), intended for monitoring the workers’ exposure to magnetic fields in particular working environments, such as hospitals or physics laboratories. The proposed microsystem is based on a multi-chip module containing three equal channels for the three components of the magnetic field measurement, a micr...

Communication structure is a way of improving the effectiveness of group communications by coordinating group members’ individual efforts. This study investigates the use of Delphi, a communication structure which has been widely used to collect ideas and opinions from geographically dispersed experts. A new approach in Delphi implementation using asynchronous ComputerMediated Communication (CM...

The SLACTM device connects to the host processor through a 3-pin serial interface. While this interface is used primarily to initialize the SLAC device, several critical functions of the SLICTM device can be monitored through the serial interface; therefore, it may be necessary to make the interface as fast as possible. Using the SSI port of the Am188EM microcontroller reduces software overhead...

One of the most important parameters to consider when designing a manipulator is the number of degrees-of-freedom (DOFs). This article focuses on the question: How many DOFs are necessary and sufficient for fault tolerance and how should these DOFs be distributed along the length of the manipulator? A manipulator is fault tolerant if it can complete its task even when one of its joints fails an...

The development of technologies of multimedia, linked to that of Internet and democratization of high speed, has made henceforth E-learning possible for learners being in virtual classes and geographically distributed. One benefit to taking course online is that the online course structure is typically more student focused than teacher centered and encouraging more active participation by stude...
