Introduction: AIDA v4 is an interactive educational diabetes simulator that has been made available, for over a decade, without charge via the Internet. The software is currently freely accessible at http://***. This report sets out a collaborative development plan to enhance the program with a new model of subcutaneous insulin absorption, which permits the simulation of rapidly acting and very long-acting insulin analogues, as well as insulin injection doses larger than 40 ***: A novel, generic, physiological subcutaneous insulin absorption model is overviewed and a methodology is proposed by which this can be substituted in place of the previously adopted insulin absorption model utilized within AIDA v4.3a. Apart from this substitution it is proposed to retain the existing model of the glucoregulatory system currently used in AIDA v4.3a. Results: Initial simulation results based on bench testing of this approach using MATLAB are presented for the exogenous insulin flow profile (Iex) following subcutaneous injections of a rapidly acting insulin analogue, a short-acting (regular) insulin preparation, intermediate-acting insulins (both Semilente and neutral protamine Hagedorn types), and a very long-acting insulin analogue. Discussion: It is proposed to implement this collaborative development plan - first by bench testing the approach in MATLAB and then by integrating the generic subcutaneous insulin absorption Iex model into the AIDA simulator in Pascal. The aim is to provide enhanced functionality and educational simulations of regimens utilizing novel insulin analogues, as well as injections larger than 40 units of insulin. © Diabetes Technology Society.

In this article there are described applications of embedded systems for diagnostic and maintenance planning in healthcare applications. During the recent years, there was a rapid growth in the development of maintenance telemedicine systems and monitoring devices for patients with chronic diseases and those requiring continuous telemonitoring treatments. However most of these systems only provide telemonitoring services or basic information about the health condition of the patients. For this reason an intelligent home health care embedded system that can provide to the patients with diagnosis their health status at home is developed. As a result different types of pluggable medical transducers for patients with different illnesses can be flexibly connected to the interface of the embedded system. The home care systems are possible to use as predictive diagnostic systems.

This paper presents a trajectory tracking control scheme for the human arm moving in sagittal plane. The arm is described by a musculoskeletal model with two degrees of freedom and six muscles, and the control signal is applied directly in muscle space. To design the intelligent controller, an evolutionary diagonal recurrent neural network (EDRNN) is integrated with proper performance indices, which a genetic algorithm (GA) and evolutionary program (EP) strategy are effectively combined with the diagonal neural network (DRNN). The hybrid GA with EP strategy is applied to optimize the DRNN structure and a dynamic back-propagation algorithm (DBP) is used for training the network weights. The effectiveness of the control scheme is demonstrated through a simulated case study.

Robots are complex systems that require multidisciplinary approach to development. Hence, both research and production of a robotic system require a tool that would provide means for coordination between teams with different areas of expertise as well as the ability to integrate, simulate and debug the system in a comprehensive way. Also, with the growing popularity of service robotics, research and modeling of human-machine interaction gains the attention. From a simulation tool, it is expected to support the means for describing this interaction. For that purpose we are investigating the ML Designer TM , not just as a possible simulation tool, but also as a modeling and design paradigm. For verification purposes we will compare it against MATLAB Simulink TM . A pneumatic system will be modeled with both tools and a comparison will be performed.

Most current Intrusion Detection Systems (IDS) examine all data features to detect intrusion. Also existing intrusion detection approaches have some limitations, namely impossibility to process a large number of audit data for realtime operation, low detection and recognition accuracy. To overcome these limitations, we apply modular neural network models to detect and recognize attacks in computer networks. They are based on the combination of principal component analysis (PCA) neural networks and multilayer perceptrons (MLP). PCA networks are employed for important data extraction and to reduce high dimensional data vectors. We present two PCA neural networks for feature extraction: linear PCA (LPCA) and nonlinear PCA (NPCA). MLP is employed to detect and recognize attacks using feature-extracted data instead of original data. The proposed approaches are tested with the help of KDD-99 dataset. The experimental results demonstrate that the designed models are promising in terms of accuracy and computational time for real world intrusion detection.

In this work we present a comparative study, testing selected methods for clustering and classification of holter electrocardiogram (ECG). More specifically we focus on the task of discriminating between normal 'N' beats and premature ventricular 'V' beats. Some of the tested methods represent the state of the art in pattern analysis, while others are novel algorithms developed by us. All the algorithms were tested on the same datasets, namely the MIT-BIH and the AHA databases. The results for all the employed methods are compared and evaluated using the measures of sensitivity and specificity.

The application of mobile robot control using multi-agents is executed in a game form within the mechatronic task of robot soccer. The game dynamic nature and the infinite number of possible strategic variations underlie the parameters and execution structure of communications systems between the main control computer and a group of mobile robots. A CCD camera monitors the action on the field. The database of possible strategic formations and movements is the first source of information for control module of programming equipment within the control computer. An advanced communication system becomes a second source of information for influence of the decision processes, allowing distribution of part information on the level of mobile robots.

This paper presents the design of an embedded control and monitoring system for small sport and ultra-light airplanes. The focus is on the system's structure and a description of module architecture. The project is aimed at reducing the number of accidents. There are a lot of ultra-light airplanes with no measurement units in the Czech Republic. A low cost flight control and monitoring system is the best solution. Ultra-light airplane is a very nice example of a mechatronic design and its realization. Copyright © 2006 IFAC.

This paper deals with method of representing robotic soccer game in a simulated and/or real form. This representation is used for controlling robots playing soccer. Our approach to robot soccer is to view it as a local interaction game. We describe our concept of virtual grid and implementation of robot soccer simulator in this paper, as tools for building the strategy and tactical movement database for real game. This strategy we will use as strategy model for 11th FIRA RoboWorld Cup. Strategy learning from game observation is important for discovering strategies of the opponent team and searching of tactical movements groups replaying, simulation and synthesis of anti-strategies.
