Grid computing systems are emerging as a consequence of the growing Internet connectivity in combination with the need of shared resources to deploy large-scale scientific applications. In such a context, heterogeneity, decentralization, location, access and availability of resources need to be dealt with suitable simulation tools. In particular, overloading conditions may be critical and difficult to analyse when the grid is requested to guarantee affordable high performances. To deal with such a challenging task, a virtual simulation environment provided with a suitable graphical interface has been developed as the means for comparative analysis with real test bed activities

We propose a multimedia framework built on a flexible architecture designed for collaborative interaction of people and robots through the Web. Users can communicate to each other exchanging text, audio and video messages. Besides, it provides a flexible interface for people to interact with robots, for robots with people, and among robots themselves, for example, allowing a robot to communicate to another one. One or several users can communicate with one or more robots and also receive information from them. Robots can be remotely controlled through the use of keyboard, joysticks, data glove, and voice commands. A user can perceive other users through a virtual environment and receive the video from an environment, in which the robot is

The interest in tactile sensors is increasing as their use in complex unstructured environments is demanded, like in telepresence, minimal invasive surgery, robotics etc. The array of pressure data provided by these devices can be treated with different image processing algorithms to extract the required information. However, as in the case of vision chips or artificial retinas, problems arise when the array size and the computation complexity increase. Having a look at the skin, the information collected by every mechanoreceptor is not sent to the brain for its processing, but some complex pre-processing is performed to fit the limited throughput of the nervous system. This is specially important for high bandwidth demanding tasks. Experimental works report that neural response of skin mechanoreceptors encodes the change in local shape from an offset level rather than the absolute force or pressure distributions. Something similar happens in the retina, which implements a spatio-temporal averaging. We propose the same strategy in tactile preprocessing, and we show preliminary results illustrated for the case of slip detection, which is certainly demanding in computing requirements

We conducted experiments on 26 elementary school pupils to measure the movements of their gaze while they were watching a news TV program for children and analyzed the relationship between the measurements and the pupil's comprehension of the program's contents. The comprehension data were acquired with a quiz-style examination after the experimental TV program. We evaluated the variances of their gaze directions by calculating entropy of the estimated gaze direction probability distributions that were represented as a mixture of two-dimensional normal distributions. The results indicate the variances of the gaze direction for scenes that gave better comprehension tended to be lower. The tendency was noticeable after a keyword utterance related to the answer to the corresponding question

This project uses an IDAC-1 board to sample and control the pH level in a tank. The whole control is performed through the Internet. The experimental arrangement is placed on the task location and the controlling computer is located in a different one. Internet is the transport media. The protocol used in this project is UDP/IP. The pH level is measured by a pH meter and its output is sampled by an A/D converter integrated on the IDAC-1. To change the pH level ON-OFF valves control the free flow of light solutions acid and alkaline. The controlling computer through the Internet acting as client asks for the pH level, the IDAC-1 responds as server with the 10-bit resolution sampling pH meter. If pH is away from the set point the corresponding valve opens, neutralizing this way the solution. The whole procedure is logged in a file on the controlling computer. This application can give the ability to the Internet user to monitor and control the pH of a solution anywhere in the Word Wide Web (WWW)

Reusable learning objects (RLO) are used in different contexts and are accompanied by their associated metadata for searching, managing, etc. This paper presents an application framework for metadata sharing, searching and visualizing techniques in a peer-to-peer network. The framework considers the semantic meaning of the query and applies context based peer address mapping to search metadata. We have also presented an algorithm for grouping metadata. By using a car metaphor, the grouped information is visualized in a 3D virtual environment for intuitive navigation and browsing that intends to show the context and relationship among the displayed results

The subject of this paper concerns the electro-physiological examination of the visual organ, the acquisition and statistical evaluation of the multifocal visual evoked potentials (M-VEP), in particular. The results presented are related to the real multifocal VEP waveforms, obtained during the examination of numerous patients in clinical conditions. The statistical evaluation of the results obtained during the examination of numerous healthy eyes enables the determination of electrical potential tolerance intervals and latency in the scope of the entire visual path of a healthy eye. Due to the lack of standardized values of the M-VEP test, the intervals may represent reference data in the valuation of various visual tract diseases. The data included therein, upon being exported to Microsoft Excel, enable the calculation of the average and standard deviation, and the tolerance intervals based on them

The system is based on a stereo vision system and provides a series of mechanisms for an efficient segmentation of the arm-hand structure over the screen and its description in terms of moments that can be used by a neural network based structure in order to provide position and gesture classification results. These can be adapted to the user's desires through an interaction and feedback mechanism permitting a natural mutual learning process between the system and the human

This paper deals with the implementation of a new approach that aims to improve the performance of high performance computing (HPC) centers through an agent based virtual interface that models the user behaviour and satisfaction. This interface translates user requests and satisfaction criteria into what is really necessary and, thus, permits the optimization of the HPC center's scheduler taking into account predicted user satisfaction together with the objectives of the management in terms of resource usage and cost. The system is based on an evolutionary profiling agent based architecture where the different agents are evolved in real time to adapt to the different users. These agents cooperate with the scheduling mechanism providing resource usage estimations for the different tasks, as well as predicting the effect of possible strategies on user satisfaction. Some experiments are presented where this system interacts with a real job management system (SGE) and we show that modelling the user and taking user satisfaction into account helps to improve system performance

In recent years the declaration of uncertainties according to the ISO GUM (1995) has pushed the development of the so called Virtual Coordinate Measuring Machines - VCMMs as a software tool to generate uncertainty estimates for industrial applications. That is, a tool to calculate measurement uncertainty estimates based on real metrology information to be used in the context of quality systems. Recent tests on commercial VCMMs have shown that the fidelity of the simulation process to the real world is as important as the numerical correctness of uncertainty calculations. In this paper a VCMM interface design is proposed, focusing on techniques to increase the software fidelity and usability in industrial metrology applications. Results show that the quality of the simulation can be improved by proper user guidance as much as the software usability by the application of basic principles of software prototyping using the MVC model
