We present the newly emerging research field of Computer Supported Collaborative Sports (CSCS). By applying innovative input and output technologies, it enables players to experience sportive activities in a shared computerized environment. Important dimensions in the design space of CSCS applications are discussed. Finally we present the FlyGuy, a prototypical realization of a CSCS device.

We consider discrete memoryless channels with input alphabet size n and output alphabet size m, where m = ⌈γn⌉ for some constant γ > 0. The channel transition matrix consists of entries that, before being normalized, are independent and identically distributed nonnegative random variables V and such that E [ (V logV ) ] < ∞. We prove that in the limit as n → ∞ the capacity of such a channel con...

We consider the problem of characterizing possible supply functions for a given dissipative nonlinear system, and provide a result that allows some freedom in the modification of such functions. Keywords— nonlinear stability, ISS, dissipation, input/output stability

The main objective of this article is to give a survey on elementary functions in the context of quaternionic analysis. We define some of their more common properties, which as in the real and complex cases, will be familiar to the reader. This leads to the consideration of quaternion-valued functions depending on a quaternion variable, that is, functions whose input and output are quaternions....

The HERA-B application software modules are house by the frame program Arte. To use Arte in the online environment of the farm, input and output streams have to be buffered and interfaced. This note describes a concept for implementation of the frame program Arte and the I/O modules in the multi-process environment of the farm.

We analyze the operational performance of 202 Turkish rural general hospitals. To help improve performance on both input and output space, we adopt a directional distance approach. We treat a mortality based measure as a “needs indicator”. We derive pure technical, scale and output congestion inefficiency measures and show how they vary across size classes. We show that “reducing mortality” inv...

This paper presents an algebraic method to design a dynamic gain unknown input observer for linear systems with commensurate delays in state, input and output variables. Necessary and sufficient conditions for the existence of such an observer are provided as well as a constructive procedure. An example is given in order to illustrate the proposed method.

We present a model for the ontogenesis of information routing architectures in the brain based on chemical markers guiding axon growth. The model produces all-to-all connectivity between given populations of input and output nodes using a minimum of cortical resources (links and intermediate nodes). The resulting structures are similar to architectures proposed in the literature, but with inter...
