Modeling methods to derive 3D-structure of proteins have been recently developed. Protein homology-modeling, also known as comparative protein modeling, is nowadays the most accurate protein modeling method. This technique can produce useful models for about an order of magnitude...

The agent technology is gaining acceptance, both in academy and industry, with regards to distributed systems development. Modeling languages and development processes were created to formalize the development of agent based systems. Nevertheless, existing modeling languages are ...

A novel approach for modeling gene-regulatory networks, based on graphical Gaussian modeling, is used to create a network for the isoprenoid biosynthesis pathway in Arabidopsis....

SWISS-MODEL (http://swissmodel.expasy.org) is a server for automated comparative modeling of three-dimensional (3D) protein structures. It pioneered the field of automated modeling starting in 1993 and is the most widely-used free web-based automated modeling facility today. In 2...

The ascape agent-based modeling environment greatly eases the task of designing and investigating agent-based models. However, effective design can still require a relatively deep knowledge of programming and agent-based modeling. This issue has almost certainly slowed the adopti...

Abstract The work presents modeling of interface phenomena in biological structures. Selected ways of numerical modeling of phenomena at the boundary of two materials by means of FEM methods are discussed. The work focuses on phenomena related to biological structures and their m...

The following resources for comparative protein structure modeling and analysis are described (http://salilab.org): MODELLER, a program for comparative modeling by satisfaction of spatial restraints; MODWEB, a web server for automated comparative modeling that relies on PSI-BLAST...

Species distribution modeling is a technique the purpose of which is to estimate models based on ecological niche. These models can assist decision making processes, planning and carrying out actions aiming at environmental conservation and preservation. There are several tools d...

In this paper we consider the modeling of heterogeneous aerosol coagulation where the heterogeneous aerosol particles (called droplets) contain smaller particles (enclosures). Droplets and enclosures coagulate with different collision kernels. We discuss macroscopic modeling and ...

This work tried to assembled the informations and the methodologies for the modeling of the corrugated paperboard by the finite element method with the objective of realize the modeling in the program ANSYS and identify the advantages and restrictions of this method. Get a packag...

This research forms part of the studies for the use of Mathematical Modeling as a teaching strategy. In her a modeling activity for teaching the sine function is presented. The research had two main objectives: to analyze the effects of mathematical modeling in high school in ord...

Abstract Decades of classical research on pyrolysis of lignocellulosic biomass has not yet produced a generalized formalism for design and prediction of reactor performance. Plagued by the limitations of experimental techniques such as thermogravimetric analysis (TGA) and extreme...

This work presents a study on modeling error estimates in linear elastic structures of heterogeneous materials. The employed formulation is based on a theory of a posteriori estimation of modeling errors and uses the Finite Element Method as numerical tool. The evaluated modeling...

This research aims to analyze the contribution of the training process conducted in a course on mathematical modeling, from an educational material developed by the research group GPECOM facing teacher education as the use of Mathematical Modeling. Analyzed specifically as the ph...

Objective: The development of tailor-made domain-specific modeling languages is sometimes desirable in medical informatics. Naturally, the development of such languages should be guided. The purpose of this article is to introduce a set of requirements for such languages and show...

The use of Geographic Information Systems (GIS)to model environmental phenomena limits decision-making processes because the products of GIS modeling, such as agriculture suitability and vulnerability to erosion maps or economic-ecological zoning, do not encompass quantitative in...

The good understanding of the organizational requirements is vital for the success of the development of applications in the area of Software Engineering. With the popularization of the object oriented paradigm, the modeling language UML (Unified Modeling Language) has became sta...

Abstract Fiber-matrix interface performance has a great influence on the mechanical properties of fiber reinforced composite. This influence is mainly presented during fiber pullout from the matrix. As fiber pullout process consists of fiber debonding stage and pullout stage whic...

Numeric methods have been a very attractive alternative in the analysis and solution of problems in electromagnetic fields. Those are applicable to a high variety of problems involving complex geometry, heterogenic material composition and boundary condition diversities. This res...
