Information and knowledge have become an important factor in product development. The approach of a CAD assistance system is for many companies a major step towards the future. For a successful integration of knowledge systems, the factors: knowledge management, KBE, object-oriented modeling, CAx-Automation and a multifunctional programming language, play a decisive role. In this paper we present an approach for a CAD assistance system based on the programming language Python. Python can control the CAD system CATIA V5 via Windows COM interface and also edit CAD data. An object-oriented modeling of CAD components facilitates a knowledge-based design. Simultaneously the knowledge of design can be created and formalized in a knowledge base (ontology). This ontology is also based on the programming language Python. Thus, an opportunity in Python has been created in which the CAD system and the knowledge management can be controlled and used in one level. Therefore this approach paves the way for a CAD-Automation or a CAD assistance system.

A new approach to pattern recognition and classification of non-stationary power signal is presented in this paper. In the proposed work visual localization and detection of non-stationary power signals are achieved using Image processing and its pattern is recognized and classified by MLP neural network algorithm. Also disturbance localization and classification of the signal, is done once with image processing and one more time with neural network and the results are compared with each other. In MLP neural network method we tried to reduce the disturbance localization errors of image processing method. Various non-stationary power signals are processed through image processing stage to generate property charts of the signal for extracting relevant features for pattern classification. The extracted features are clustered using MLP Neural Network algorithm to refine the cluster centers.

The paper presents an ICT tool to support the physicians in their clinical activity assessing and monitoring the cases which lead to preterm birth. The basic ICT tool is an open source called Labkey Server which has the ability to make statistics, reports and other important charts which can help the clinicians and the researcher to prevent the preterm birth. The data will be gathered from multiple databases from different departments or laboratories and processed to adapt to situations and supply the appropriate solution to assist the clinician. The communication is based on HL7 CDA (Clinical Document Architecture) standard. The process will be applied to support detection of risk problems related to pregnancy which if are not detected in time can lead to preterm birth. The proposed platform will be used in the future to perform algorithms adaptable to specific situations and patients in order to add a smart component that can alert the clinician in case of higher risk pregnancy situations.

The paper deals with a time-domain (transient) model of a microturbine power unit for the design, optimization, and verification of control equipment. The model includes the starter motor, generator, gearbox, and single-shaft gas microturbine. In addition to the normal operational performance the model allows simulating various faults including failed ignition in the combustion chamber. Explicit formulation of the differential equations of the model allows computationally effective implementations in a hardware emulator.

Computed tomography scanners (or CT scanners) are very popular medical equipments for tens of years. Its invention initiated a revolution in diagnostic technology by allowing us to look inside a person and obtain a very clear anatomical image without violating the outer surface of his body, in other words, non-invasively [10]. Just few years ago this technology found way to the area of industrial applications and especially to geometrical metrology. Metrotomography is a term that consists of words metrology and tomography. Presented paper describes metrological possibilities of industrial tomography in the area of biomedical engineering in order to hardware limitations and software functions. Specific prosthetic and biomedical experiments were realized by Metrotom 1500 (Carl Zeiss, Germany) at the Technology center of computed tomography, Department of Biomedical Engineering, Automation and Measurement, Technical University in Kosice.

The paper offers a Previous and Current Cycle Learning (PCCL) approach to the position control of a 3D crane system laboratory equipment in the framework of a new Iterative Learning Control (ILC) structure. The PCCL structure is constructed around a control loop with a frequency domain designed lead-lag controller, and a real PD learning rule is involved. A frequency domain convergence condition is applied to design the learning rule. The design of the ILC structure is illustrated by real-time experimental results related to the position control.

The study deals with thermographic (IRT) diagnosing in neuro-vascular diseases of the human hands such as the Carpal Tunnel Syndrome (CTS). It is considered to be an approach to screening thermal manifestations of the difference between the physiological temperature distribution in the skin of dorsal hands and pathophysiological temperature distribution in hands affected by CTS. We created a database of 178 thermal images of dorsal side of 162 healthy (nRS= 162) and 16 pathological hands (nCTS=16) with clinically diagnosed CTS of 9 patients. Pre-surgical thermograms of the hands with CTS of each subject were taken and stored using IRT (Thermocamera Fluke Ti55/20). We observed the temperature distribution in the entire hand and partial temperatures of the center point of carpals (D1) as well as the area of distal phalanges on middle fingers (D5). The Index of Median Nerve (DMI=(TD1−TD5) was determined based on resulting data. Test results obtained from measurements of the two points on the dorsal side of hands showed that the temperature of CTS hands is typically higher in the phalanges as opposed to the wrist (DMI<0, 62.5%), while the temperature is the lowest in distal phalanges (D5) of healthy hands (DMI≥0, 81.5%). The sensitivity of IRT diagnostic test in our diagnostic process of CTS was calculated to be 0,625. Results will be confirmed by further termal screening of statistically significant group of patients.

Nowadays it is a frequent problem that, the infrastructure-development of land transportation comes up against space limits in many cases, moreover the growth of traffic doesn't slack up. This is particularly typical for urban traffic, effecting traffic jams, lags; not to mention the problem of air pollution. In this case the requirements of sustainable development can be satisfied by the optimization of the existing infrastructure. This procedure always begins by observing, collecting and processing information, followed by model creation. In the next step the identified model will help us to analyze even the most extreme situations through different simulation environments and to prepare different traffic analyses.

In the paper general case of nonlinear stochastic dynamical system is considered. The sufficient conditions for robust application of the suggested method are proven with a theorem, applying the theory of nonlinear operators of the functional analysis. As a special case a model of a class of dynamical systems with nonlinear stochastic perturbation is also considered and the sufficient conditions for robust application of the suggested method are proven with the same theorem. An example for the latter case, comparing the numerical computer solution of the original system and the analytical solution of the approximate robust model are given. The method can be applied for analytical and computer modelling of nonlinear stochastic dynamical systems, optimization, synthesis of computer control and for investigation of the stochastic perturbation.

This present work presents a recognizer based on the combination of three Support Vector Machine (SVM) classifiers whose inputs have different parameters from characters. The three approaches of feature extraction for handwritten off-line digits, capital letters and lower case letters, have been chosen for improving the combination using database NIST-SD19. We have applied pre-processing in order to achieve greater inter-class discrimination and similarity. These three feature extractions are based on Kirsch masks with and without slant correction and Fourier elliptic descriptors.
