Handwriting process is one of the most complex processes of our biological repertory. Modelling of such process remains difficult to implement. Several approaches were proposed in the literature. However, the validation results of these models remain less or more satisfactory and the basic models were the subject of improvement in the objective to approach reality as much as possible. This paper deals...
The local authorities have a fundamental role in improving the traffic & environment system of their urban jurisdictions. Locally developed tailor-made solutions, based on active public participation processes, are essential to make the city more attractive, cleaner and healthier thus, a better place to live, work, and play. This challenge, of sustainable urban transportation, demands a comprehensive...
Designing complex embedded systems is a challenge, which benefits from using models for various tasks. Among them, an important one is finding a good (or the best) system design alternative for a given set of changeable parameters. Such decisions are usually based on non-functional properties which can be quantitatively expressed and evaluated using a model. Automatic optimization would be advantageous,...
This paper presents an algorithms combination for representation of discussion threads messages in for a for distance education. This combination inputs discussion threads from distance education for a and outputs specific strings representing the messages of these threads according to concrete modelling based in a formal language.
The aim of this work is to describe the design, implementation and evaluation of an e-learning course focused on scheduling jobs in a computer grid. These topics belong to applied informatics master's study program. Themes of grid scheduling are part of courses, term and research projects. Our course titled Research project uses inter-subject relations among distributed operating systems, optimization,...
The growing number of installed photovoltaic plants is making the possibility of simulating their behavior and effects on the power network more and more relevant. In this context an accurate yet simple model of the panels is necessary for the evaluation of the power production as well as of the system efficiency in off-line and on-line simulation. In the preliminary stages of large plant design,...
The requirements and design level identification and representation of dynamic variability for adaptive systems is a challenging task. This requires time and effort to identify and model the relevant elements as well as the need to consider the large number of potentially possible system configurations. Typically, each individual variability dimension needs to identified and modelled by enumerating...
This paper presents a new method for rapid simulation model generation using cladistics, a technique commonly used for evolutionary analysis in biology. In this research, cladistics is adopted as a basis for classification of problems typically found in manufacturing systems particularly assembly lines. The basic premise in this research is that manufacturing systems evolve (e.g. from craft production...
This paper provides an overview of the computer simulation software and models of microstructural development in cement based materials. Six representative models are introduced including model provided by H.M. Jennings, HYMOSTRUC, Navi's model, DuCOM, CEMHYD3D and CCBM. Furthermore, the development, hypothesis and application of there models are analyzed. Finally, it is underlined that microstructural...
The paper presents the question-answer approach to programming of human-computer interactions (HCI) during the collaborative development of software intensive systems. The effectiveness of the common work can be increased essentially if the human part of the work will be fulfilled as an execution of a special kind of programs by “human processors” which use the models of question-answer reasoning...
The electromagnetic modelling of existing large hydro generator is the main focus of this paper. Electromagnetic commercial software was used where all geometrical parameters of the generator are taking into account such as: pole face geometry, air gap size, the slots geometry and pattern winding sequence. The approach used to model the machine and some simulation results are presented in this paper...
This paper deals with the use of computer simulation with the aim of design efficient production in manufacturing and production systems. In our case, the possibilities of such use are demonstrated on particular example from industrial practice. The purpose was to build up a model of the prepared manufacture system and, especially, to propose a solution designed to increase productivity and to find...
The paper introduces the deterministic model and stochastic model of the nonlinear and asymmetric time-delay gene transcriptional regulation system, and researches the properties of stochastic system with the delay time by computational modeling. With the delay time increasing, it is found that the peak of probability distribution in high steady states is increased, and the peak of probability distribution...
With the development of the computer technology and the numerical technology, inverse analysis method has been widely applied to identify the mode parameter. The parameter identification methodology mainly includes the selection of the appropriate experimental data, the definition of the objective function and the optimization algorithm. However, little study has been reported on how to define the...
The main goal of this paper is to introduce the tool Kaira that we are developing. This tool is intended for modelling, simulation and generation of parallel applications. A developer is able to model parallel programs and different aspects of communication using Kaira. The used model is based on the variant of Coloured Petri Nets. Coloured Petri Nets provide the theoretical background. We use their...
In this paper, recurrent adaptive neuro-fuzzy inference system (RANFIS) structure has been proposed to solve approximation problem in identifying a global model of steam temperature of packed distillation column in steam distillation essential oil extraction process. The input-output data is acquired from field experimentation via MATLAB Real-time Workshop (RTW) integrated to the plant. The derived...
Maya is thought as the strongest 3D developing software, especially the complicated scene, which inheritted the characteristics of extendibility and adjustability. In the paper, the film 3D animation design based on Maya is proposed. The detailed creating process of animation by maya are described, which includes five stages of modelling, material, map design, light and camera, animation. The cartoon...
Modelling and simulation of the organization structure, communications and functionality of the brains of living creatures has been of interest to philosophers, scientists, engineers and artists for centuries. The possibilities for large numbers of simple microprocessors to be programmed to operate in a way which mimics the human brain, raises the knotty problem of how to do parallel programming....
Motion models have been applied as a solution to the problem of respiratory motion in a range of applications. Such models predict motion fields based on 1-D signals or signal combinations. These signals often measure the motion of a region of the subject's anatomy, such as the chest surface or diaphragm. The hypotheses we investigate in this paper are that the predictive accuracy of motion models...
This paper presents a simulation model of linear switched reluctance motor drives. A Matlab-Simulink environment coupled with finite element analysis is used to perform the simulations. Experimental and simulation results for a double sided linear switched motor drive prototype are reported and compared to verify the simulation model.
