This article examines the supporting mathematical methods for modeling and simulation of computer networks. The authors discuss approaches to composition of analysis-able mathematical models for computer networks. The DFG (Dichromatic Functional Graph) is investigated as a relevant theoretical basis. Furthermore, the approaches to modeling of elements and transmission media on the basis of even...

In the present work, the solidification process was simulated in both macroscopic and microscopic scales. Two-dimensional heat transfer equation for conduction was applied for macroscopic modeling using enthalpy formulation and finite element method. In order to decrease execution time and/or memory capacity in finite analysis, skyline mathematical technique was adapted. The microenthalpy metho...

influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.observations show that without a vent hood, there is a downward gas flow in theflu...

The main goal of computer animation is to synthesize the desired motion effect which is a mixing of natural phenomena, perception and imagination. The animator designs the object's dynamic behavior with his mental representation of causality. He/she imagines how it moves, gets out of shape or reacts when it is pushed, pressed, pulled, or twisted. So, the animation system has to provide the user...

This paper introduces a rapid prototyping methodology which overcomes important barriers in the design and implementation of digital signal processing (DSP) algorithms and systems on embedded hardware platforms, such as cellular phones. This paper describes rapid prototyping in terms of a simulation/prototype bridge and in terms of appropriate language design. The simulation/prototype bridge co...

Most agent-based simulation toolkits are based on the Java programming language. This makes their use difficult for social scientists, who are usually not skilled in computer programming. However, agent modelling concepts are not unlike those which could be used for the modelling of social systems. This assumption is considered in proposing the use of a graphical agent-oriented language for the...

This paper studies a general methodology and an associated tool for translating AADL (Architecture Analysis and Design Language) and annex behavior specification into the BIP (Behavior Interaction Priority) language. This allows simulation of systems specified in AADL and application to these systems of formal verification techniques developed for BIP, e.g. deadlock detection. We present a conc...

Background and objectives: Educational technology is widely used in all parts of medical education. The use and application of common educational technologies and adoption of educational design patterns in medical sciences education can greatly help in medical simulations, training, and improving of clinical skills of nurses and medical students. The aim of this research was to study computer-a...

A problem which must be dealt with by any reasonably general computer simulation of the cognitive processes underlying natural language dialogue behaviour is the inherent fuzziness of natural language and human thought. Artificial Intelligence (AI) research has to date achieved nothing approaching a general formal treatment covering all aspects of fuzziness. Surveys of AI approaches to the prob...

Research is reviewed that addresses itself to human language learning by developing precise, mechanistic models that are capable in principle of acquiring languages on the basis of exposure to linguistic data. Such research includes theorems on language learnability from mathematical linguistics, computer models of language acquisition from cognitive simulation and artificial intelligence, and ...
