We have already proposed a bilateral control scheme with energy balance monitoring under time-varying communication delay. In this paper, experimental results using the proposed control scheme over the computer network are shown. In the previous work, we dealt with a situation when the communication is in breakdown. However, we did not discuss how to recover the system after the communication l...

Back-pressure is a logical mechanism to control the flow of information on a communication channel of a latency-insensitive system (LIS) while guaranteeing that no packet is lost. Back-pressure is necessary for building open LISs and it represents an interesting design alternative also for closed LISs because it makes possible to realize highly modular implementations with more predictable feat...

We will demonstrate a setup involving a communication board (for manual sign communication) and a drawing robot, which can communicate with each other via spoken language. The purpose is to help children with severe communication disabilities to learn language, language use and cooperation, in a playful and inspiring way. The communication board speaks and the robot is able to understand and ta...

The curse of the Revelation Principle is that it leads us to focus on unrealistic mechanisms in which agents report all private information to the principal, who then makes all decisions centrally. This is not true when communication costs are introduced. Then partial communication of information, sequential back-and-forth conversations, and decentralization of decisions become part of optimal ...

Recent research suggests that surface electromyography (SEMG) abnormalities during flexion are highly associated with low back pain, and specific treatments that target these abnormalities are beginning to emerge in the literature. This article describes one such treatment that uses a device called the MyoRackTM to decrease muscle tension in the low back and improve strength and flexibility in ...

Machine-to-Machine (M2M) Communication is one of the most attractive technology used in both industrial and education sectors and that is predicted to grow within the next few years. It provides a way of communication between connected devices. Very important obstacles which will cut down M2M Communication growth and even hold back the large roll-out of sure applications are security and privac...

In this paper, we propose a novel self-healing approach for a computer system based on Back-Doors (BD), a system architecture that allows monitoring and repair actions to be performed on a remote operating system or application image without using remote CPU cycles. The key ingredient of the Back-Door architecture is the Remote Memory Communication (RMC) technology provided by standards like Vi...

An optical receiver for 40 Gbit=s communication systems with 8274 V=W conversion gain and 950 mVp–p limiting differential output is reported. A back-to-back sensitivity of 9.4 dBm at a bit error rate of 10 12 was observed for a 2 1 pseudorandom binary sequence. The receiver incorporates an InP based pin diode, a transimpedance amplifier and a limiting amplifier. This is the largest conversion g...

We present the fabrication and characterization of monolithically integrated transceiver chips with vertical-cavity surface-emitting lasers (VCSELs) and PIN photodetectors for bidirectional optical data communication at 850 nm wavelength over a single butt-coupled standard multimode fiber. With such a low-cost transmission configuration, data rates of 9Gbit/s in back-to-back mode and 7Gbit/s ov...
