The growing number of threats and attacks, that are also present in encrypted communication, give a great importance to Intrusion Detection and Prevention Systems (IDPS). Some of these attacks have a great impact on service availability. This paper presents a way of detecting these attacks and threats by correctly classifying the early recognized encrypted applications. The proposed architecture uses anomaly detection in comparison with early recognized encrypted applications to determine intrusive and non-intrusive behavior.

Supervisory control application forms a core for comprehensive control of industrial processes. Industrial application of this character consists of many components providing the whole supervisory control system functionality. The most important issues in supervisory control are data acquisition from technological process level, visualization of process together with control function, alarm situations indication, display trend of process variables and other components. This article presents graphical objects used in visualization screens to show what is happening at technological level of controlled process with trend objects as an important part of supervisory control application, using software products from Wonderware Corp.

This paper presents a 3 DOF robotic arm used for drawing on a paper sheet. The robotic arm is constructed using LEGO NXT bricks. The purpose of the development was to create a control system of the servo motors for the robot, as well as the inverse kinematics, used for moving the arm. The NXT controller is running LejOS for optimal motor control, while inverse kinematics is being calculated on a PC connected to the NXT via bluetooth. The robotic arm is well applied in education projects about robotics and robot programming.

The Minnesota Code is the evaluation method of reference ECG signals. The experimental studies compare the effectiveness of the computer based Minnesota Code applications to human usage of the code system, and the results showed that computers are as effective in the evaluation of ECG signal with the Minnesota Code as humans are with visual analysis. A fuzzy-based approach can be used to bypass known imperfections and imprecision of the existing Minnesota Code rules. A fuzzy-based approach also has issues with corner case inputs, which can lead to incorrect partial results and incorrect diagnostics outputs. The fuzzy environment provides more information for the medical expert or for the further levels of the whole hierarchically organized diagnostic structure. The authors of the paper present a possible solution for fine-tuning the diagnostic rules using neural networks. In this paper, the standard fuzzy-based approach is extended to a neuro-fuzzy solution.

Tissue engineering's main objective is to create therapeutic constructs in vitro, capable to replace or remedy the functions of the tissue affected by different disease or totally destroyed. In order to obtain these constructs, the living cells are cultured on the different structure biomaterial. It has been shown that these constructs have properties which are similar to ones of human tissue, if the seeding is uniform. The paper presents a set of simulations of cell spreading on the plane surface of a biomaterial, based on the Metropolis Monte Carlo method. The model taken into account is formed of a cell aggregate placed on the planar surface of a parallelepipedic biomaterial. We study the influence of the cell-substrate and cell-medium interfacial tension parameters on the cell spreading process, analysing the number of cells attached to the biomaterial and the spreading rate of the cells. We also analyze the evolution of the centre of mass for the same value of cell-substrate interfacial tension and for different values of cell-medium interfacial tension. Experiments show an uniform and rapid cell spreading results if the cell-substrate and cell-medium interfacial tension have lower values.

As the society evolves and the population grows, the demand for electrical energy increases. Search for new energy resources, increase the efficiency of the existing power plants, and cost minimization are actions to be taken. One way to reduce the cost is predicting the need for electricity. This problem is not new. This paper presents a low-cost method for short-term electric load prediction. After studying his stability, the algorithm is implemented in LabVIEW and a week of power data is used to test it and assess its performance.

We propose, in this paper, a global approach, based on a formal modeling of the mobile Human-Computer Interaction. It aims to analyze an ubiquitous environment using ontology, described in OWL; and modeling the environment by using a combination of Petri Nets and XML as the Petri Net Markup Language (PNML). In our research, we are interested particularly in the integration of OWL with PNML. How to ensure data exchange between the analyzing and modeling phases of a Human-Computer System? And how can the OWL data feed our Petri Nets?

This paper deals with robust control of linear parameter varying (LPV) system (synchronous motor) by a LPV controller. State space equations of asynchronous motor in d-q rotating frame are nonlinear with respect to rotor speed. Nonlinear equations are rewritten to parameter form describing dependency on rotor speed which is assumed to be known by measurement or by estimation. LPV controller is designed using H∞ theory to govern stator currents of synchronous motor. Simulation results presented in this paper show that current controller provides good current tracking over whole range of rotor speeds.

The article is focused on diagnostics in the field of aviation turbo-jet engines. Evaluation of their technical status, and potential failures and pre-failure processes can be improved by monitoring their thermally loaded components. Part of the research in the given area also involves mathematical modeling of the channel measuring the exhaust gases temperature, using neural networks to compensate for dynamic errors of slow thermocouples used in such measurements.
