This paper presents a Functional Electro-Stimulation distributed architecture based on a wireless network, for therapeutic training of disabled patients. On this distributed architecture, the movement (of disabled members) is artificially controlled by means of a global controller which pilots a set of stimulation units. The closed loop control system we developed for controlling muscle is base...

Our goal is to answer the question: compared with experimental structures, how useful are predicted models for functional annotation? We assessed the functional utility of predicted models by comparing the performances of a suite of methods for functional characterization on the predictions and the experimental structures. We identified 28 sites in 25 protein targets to perform functional asses...

Measurement error occurs in many biomedical fields. The challenges arise when errors are heteroscedastic since we literally have only one observation for each error distribution. This paper concerns the estimation of smooth distribution function when data are contaminated with heteroscedastic errors. We study two types of methods to recover the unknown distribution function: a Fourier-type deco...

Grid computing aims at offering standardized access to heterogeneous and distributed resources for scientific communities. In order to ensure certain quality of service requirements, the interconnecting networks have also be considered as Grid resources and must be taken into account for the co-scheduling process. However, most current systems do not support co-allocation of heterogeneous netwo...

We consider an integrated service system, where real-time (RT) calls of multiple rate requirements and non-realtime (NRT) calls share the total system capacity. Typically, RT calls are given strict priority over NRT calls, therefore, NRT performance is dependent on the RT process. When RT call arrival processes are not Poisson processes, the effect of the RT traffic burstiness on the NRT perfor...

Due to increased complexity and extreme quality of service requirements, traditional means for performance evaluation of telecom networks do not always suffice. The most flexible approach has been, and still is, simulation, which is the main focus of this paper. However, severe problems regarding efficiency exist, e.g. evaluation of ATM cell loss rate in range of <10-9 which is very computer in...

Attention is a crucial brain function for human beings. Using neuropsychological paradigms and task-based functional brain imaging, previous studies have indicated that widely distributed brain regions are engaged in three distinct attention subsystems: alerting, orienting and executive control (EC). Here, we explored the potential contribution of spontaneous brain activity to attention by exam...

According to the Complexity Theory, there is complexity in the system when the functional requirement is not be satisfied. There are several study performances for Complexity Theory based on Axiomatic Design. However, they focus on reducing the complexity in their study and no one focus on method of analyzing the complexity in the system. Therefore, this paper put forth a method of analyzing th...

Testing of multi-user applications under realistic and stress loads remains the only way to ensure appropriate performance and reliability in production. The author outlines some issues to consider for performance testing of distributed business applications and presents the typical pitfalls from the practical point of view. While the original objective was to contrast load testing with functio...

In this paper we show guidelines for performance testing through BRAIN Candidate Mobility Management Protocol (BCMP). At first, we investigate the main issues of our tests, then we describe briefly the applied TTCN-3 based distributed parallel test environment. We present the structure of the network to be tested and the Mobile Node Emulator, the main functional element of the performance test....
