Currently the finite-element method (FEM) is considered as the most promising analysis tool among the existing methods of analysis which are usually based on the continuum mechanics approach, but accuracy of the FEM solutions for nonlinear problems of solid mechanics can be hardly guaranteed and the computing cost is still prohibitive. To overcome such a drawback of the nonlinear FEM including their application to reinforced concrete folded plate structures, this paper presents the application of the harmonic coupled finite-strip method (HCFSM) to structure stability analysis. The theoretical stress-strain relations of various concrete strength classes and reinforcement, knowing only the minimum number of mechanical material parameters that come from standard test procedures, are determined from the rheological-dynamical analogy (RDA). As an illustrative example, a feasible reinforced concrete folded plate structure is analysed in detail. The ultimate resistance of two characteristic cross sections of a folded plate structure is calculated using working diagrams of concrete and steel according to Eurocode 2 and according to the RDA. Diagrams of interaction N u-M u are drawn for several combinations of material working diagrams and are mutually compared.

Today, kiosk automata (kiosks, for short) are used for variety of services from all sort of kiosks for providing information's, to kiosks for paying tickets and ATM's. Kiosks are usually programmed either using high level programming languages, like C++, or using HTML in conjunction with web browser. In this paper, we analyzed a vast range of kiosk automata and derived common characteristics. We present approach for programming kiosk applications based on Domain Specific Language (DSL), designed specifically to meet the needs of developing kiosk applications that are usually programmed using high level programming languages and are deployed on kiosks with touch-screen monitors. Our goal is to make development of such kiosk applications more rapid, while minimizing number of programming errors.

Processor cores are becoming less expensive and thus more accessible. To utilize increasing number of available computing elements, good parallel algorithms are necessary. In light of these changes in contemporary computing, multipath Metropolis simulation of classical Heisenberg model is explored. In contrast to the original single-path algorithm, multipath simulation approach is inherently parallel because different random-walk paths are mutually independent. This independence enables easy and efficient harnessing of numerous cores' computing power in embarrassingly parallel algorithms. Aside form being inherently parallel, multipath simulation approach results in independent and normally distributed simulation output. Normal distribution enables simple and straightforward statistical processing. Thus, multipath simulation results can be easily computed with arbitrary and statistically known precision.

We present, a wireless sensor network application programming and simulation system, suitable for wireless sensor network application development for both resource constrained and unconstrained hardware. Developed programs can be tested inside simulator, or (with source unchanged) executed directly on hardware. Main contribution of our project is uniform object oriented programming model with predefined basic concurrency abstractions.
