modeling and simulation techniques are now widely used alongside with their experimental counterparts in order to complement them, or sometimes to bring first insights into the possible outcome of experiments. “modeling” is a general word that could encompass a wide range of methods that could be applied to a variety of subjects and problems. here, the use of selected molecular modeling methods...

This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...

despite the crucial role of introductory sections in argumentative academic writing, the effects of genre- based approaches to writing introductory paragraphs have not been much explored yet. the present study aimed to investigate whether the provision of genre knowledge through modeling and non-modeling could enhance learners’ ability in writing introductory paragraphs of argumentative essays....

a linear superposition method was used for modeling the time history of the production blast vibrations and optimizing the blast sequence to reduce vibration levels in sar-cheshmeh copper mine, kerman, iran. a single-hole blast for modeling and two double-hole blasts with time delays of 25 and 65 ms between two holes for modeling validation were carried out. the generated vibrations were measur...

the aim of this paper is to study the popular models used for the simulation of major elements of a water quality system. the present study compares results of the ce-qual-w2 model with the wasp5 and mike11 models to assess the water quality of pasikhan river. the contaminant loadings of nitrate and phosphate are utilized in the ce-qual-w2, wasp5 and mike11 simulations. this study is the first ...

the geometric distribution of states duration is one of the main performance limiting assumptions of hidden markov modeling of speech signals. stochastic segment models, generally, and segmental hmm, specifically, overcome this deficiency partly at the cost of more complexity in both training and recognition phases. in this paper, a new duration modeling approach is presented. the main idea of ...

This contribution focuses on the behavioral modeling of the systems in the system engineering. The system engineering process is described and overview of the system modeling language (SysML) is presented. The SysML basic principles and diagrams are discussed. Practical part of the paper discusses behavioral modeling process, which is illustrated by the set of the example models. Key-Words: Sys...

the main purpose of present paper is the modeling of onion drying process and investigation of experimental data of onion drying obtained with using a hot air dryer. therefore some empirical and regression models have been considered to fit experimental data. the investigation of the experimental data shows the onion drying happens only in falling rate zone. the experimental data have been fitt...

reliable stress-strain behavior of concrete is necessary particularly when a member is subjected to combine bending and axial load and confinement effects should be accounted for. a unified theory for confinement of circular hollow sections is proposed herein, that can be extended to the case of solid and noncircular sections. the main aim of the model is to trace step-by-step the evolution of ...
