Opis:
The real time monitoring of environment context aware activities is becoming a standard in the service delivery in a wide range of domains (child and elderly care and supervision, logistics, circulation, and other). The safety of people, goods and premises depends on the prompt reaction to potential hazards identified at an early stage to engage appropriate control actions. This requires capturing real time data to process locally at the device level or communicate to backend systems for real time decision making. This research examines the wireless sensor network and radio frequency identification technology integration in smart homes to support advanced safety systems deployed upstream to safety and emergency response. These systems are based on the use of hybrid intelligent decision support systems configured in a multi-distributed architecture enabled by the wireless communication of detection and tracking data to support intelligent real-time monitoring in smart buildings. This paper introduces first the concept of wireless sensor network and radio frequency identification technology integration showing the various options for the task distribution between radio frequency identification and hybrid intelligent decision support systems. This integration is then illustrated in a multi-distributed system architecture to identify motion and control access in a smart building using a room capacity model for occupancy and evacuation, access rights and a navigation map automatically generated by the system. The solution shown in the case study is based on a virtual layout of the smart building which is implemented using the capabilities of the building information model and hybrid intelligent decision support system.

Opis:
In the solar energy application, there are several obstacles during the design of projects. The investors are still enforcing with deliberately carrying out the right and feasible project decision. In this point simulation techniques have been emerging their indispensable importance. Thereby the simulation can be used as an adaptive purpose not only during the design process of a plant but also for the existing plants efficacy while determining operational condition of solar system on a daily basis by probabilistic methods due to random characteristics of the meteorological data. This study mainly consists two parts. The first part of this study overarches the review of existing software tools and models which are reachable at the preparation time of this study. Then the reviewed software tools and models were classified briefly in the figures. The second part of the study outlines the developed new code in C# computer programming language for the solar calculations. The results which were obtained framed the developed code, were evaluated with the convenient existing software tools and models for assessment of their correlation and also the results were demonstrated with graphs for their utilization. Consequently the software systems were enlightened that are mostly used in scientific projects including solar software simulation packages and modeling background together with comparison of separate or combined PV software programs by their field of application which would bolster further research studies.

Opis:
Electrostatic energy analyzers are irreplaceable instruments to analyze the electron beams energies. In this context, the knowledge of electron trajectories in electrostatic energy analyzers has major importance in collision physics as well as in different scientific instruments for surface science. In this study, electron trajectories for different energies in an ideal field 180° hemispherical deflector analyzer are investigated by artificial neural network prediction method. The SIMION 8.1 simulation program is used as a data source for training and testing of artificial neural network. Artificial neural network based prediction has been performed using Matlab R2012b program. Obtained performance results indicate that this approach provides new perspectives for the rapid solution to the problems in charged particle optics.

Opis:
Simulations are performed according to the Axelrod model of culture dissemination, with modified mechanism of repulsion. Previously, repulsion was considered by Radillo-Diaz et al. as dependent on a predefined threshold. Here the probabilities of attraction and repulsion are calculated from the number of cells in the same states. We also investigate the influence of some homogeneity, introduced to the initial state. As the result of the probabilistic definition of repulsion, the ordered state vanishes. A small cluster of a few percent of population is retained only if in the initial state a set of agents is prepared in the same state. We conclude that the modelled imitation is successful only with respect to agents, and not only their features.

Opis:
In this study, an optimization analysis of the hydraulic gear pump cover with design of experiments and response surface method has been conducted. The sample of the solid cover of a hydraulic pump has been parametrically modelled. Structural strength analysis of the modelled hydraulic pump cover has been realized using finite element method. To prevent the concentration of stress on the hydraulic pump cover and to keep the stress values on the safe side, design inputs were not exceeded. According to the analysis results of this optimization study; the wall thickness of the hydraulic pump cover has been reduced. Finally, experimental tests were performed on hydraulic pump test setup, for verification of the simulation results.

Opis:
The implementation of the remote control, monitoring and maintenance of industrial automation systems based on real-time criteria is becoming more difficult as the distance increases. ATM is an important transport, switching, network management and backbone technology that offers different solutions to real-time communication with different classes of service. In this study, the effects on real-time communication of AAL 3/4 and AAL 5 classes of service of ATM were researched on a model in which the communication between WorldFIP industrial network nodes and ATM network nodes was provided over a bridge. First, a communication system consisting of a WorldFIP network, ATM network and bridge were modeled on a simulation tool and implemented. Afterwards, the system performance was analyzed under different loads within the classes of service AAL 3/4 and AAL 5. The analysis results have indicated that compared to AAL 5, AAL 3/4 better satisfies the real-time communication criteria. This result has shown that in both real-time access to a remote industrial automation systems and communication among remote industrial automation systems, ATM is preferable as a backbone and AAL 3/4 as the class of service.

Opis:
Physical and mathematical models as well as numerical algorithms for simulation of advanced technological processes, such as thermal annealing after low-energy ion implantation used during the VLSI fabrication are presented. In this paper we propose a model that treats the migration of the impurity atoms at the thermal annealing. We take into account process nonlinearity and influence of non-uniform defects distribution as well as electric field and elastic stress on the migration of atoms. The redistribution of point defects as well as the diffusion of nonequilibrium impurity interstitials in silicon are described by time-dependent quasi-linear parabolic equations. The results of numerical calculations are presented as well.

Opis:
In this study, design of an electronic air-conditioning system was carried out using Matlab/Simulink software. The air-conditioning system was designed as a laboratory experimental setup. The aim of this study was to revise and to reuse an outdated air-conditioning laboratory unit, by using improved methods. General equations were defined separately for each part and cell of this air conditioning system. Using these equations Matlab/Simulink models for every component were created. The Matlab/Simulink models were combined and verified with theoretical results. The simulation results show that theoretical results are compatible with the simulation results. These results were tested for input and output air enthalpy values and for humidity values. In addition, air mass flow rates for the number of different fan speeds were compared. The coherent simulation results showed that the general model of the air conditioning system, designed in Matlab/Simulink, behaves correctly. This model will be used in the future studies for comparison of real system results with simulation results.

Opis:
New specialized sampling converter for signal timescale transformation and algorithm of digital signal processing for automated measurement of settling times of fast digital-to-analogue converters is represented. The new sampling device with numerically controlled oscillators allows us realization of different types of the timescale transformation. Usage of ΣΔ analogue-to-digital converter and first-in first-out memory allows us significant simplification of the device. The equations of timescale transformation ratio and sampling step are presented. A method using a brick-wall comb filter in frequency domain to filter measurement signal has been developed. It is shown that such filtering allows us significant reduction of noise of measurement signal. A new method and algorithm using a brick-wall comb filter and averaging of filtered signal has been developed. Results of the research of developed digital signal processing algorithm are submitted.
