2. Modelagem de processos de negócio: efeito do método de notação no nível de ambiguidade
Resumo A proposta deste estudo experimental controlado e aleatorizado foi analisar a especificação de requisitos funcionais. Avaliaram-se os possíveis impactos do método de notação de modelagem de processo no nível de ambiguidade presente na especificação em linguagem natural. As notações foram utilizadas como instrumento para manifestar as nece

4. MODELING SOIL WATER REDISTRIBUTION UNDER SURFACE DRIP IRRIGATION
ABSTRACT The main objective of this study was to develop a numerical model to simulate water distribution, and the shape of the wetted soil volume, resulting from a point source irrigation at the ground surface (dripper), given soil hydraulic properties and irrigation system parameters. The mathematical model was developed in Fortran 90 at the Department of

5. Credibility, audacity and joy: Brand personalities that connect users to social media
Abstract The main purpose of this article is to evaluate the influence brand personality has on customer loyalty in the context of social networks as brands. We conducted a survey of 268 social networks users in Brazil and analyzed data through Structural Equation Modeling. As a result, brand personality dimensions Credibility, Audacity and Joy were found to

6. On the performance of three indices of agreement: an easy-to-use r-code for calculating the Willmott indices
ABSTRACT A key step for any modeling study is to compare model-produced estimates with observed/reliable data. The original index of agreement (also known as original Willmott index) has been widely used to measure how well model-produced estimates simulate observed data. However, in its original version such index may lead the user to erroneously select a p

7. Prediction of Plastic Instability in Sheet Metals During Forming Processes Using the Loss of Ellipticity Approach
Abstract The prediction of plastic instability in sheet metals during forming processes represents nowadays an ambitious challenge. To reach this goal, a new numerical approach, based on the loss of ellipticity criterion, is proposed in the present contribution. A polycrystalline model is implemented as a user-material subroutine into the ABAQUS/Implicit fin

8. AnaBioPlus: a new package for parameter estimation and simulation of bioprocesses
Abstract A very important step in the study of bioprocesses is the modeling and simulation of bioreactors. This paper presents the AnaBioPlus software package, which was developed for teaching and research purposes concerning the analysis of bioreactors. The package consists of two programs: OptimusFerm and SimulaFerm. OptimusFerm allows the analysis of expe

9. Técnica de realidade virtual para manipulação e deformação de superfícies NURBS
The Virtual Reality (VR) mainly deals with the creation of three-dimensional environments generated in real time and made available for multisensory interaction with different devices. A high processing capacity and modeling environments is required for applications of this nature. These applications currently extend to various productive sectors such as ind

10. Application of computer graphics in facial reconstruction for recognition: a case study / Aplicação da computação gráfica na reconstrução de face para reconhecimento: um estudo de caso
The facial reconstruction, also known as facial approximation, is performed for centuries by forensic medicine professionals and anthropological areas researchers. In the forensic medicine, for example, it is used when there is no evidence that allows the identification of the individual by considered accurate means, such as DNA testing or dental records. Th

11. Istar : um esquema estrela otimizado para Image Data Warehouses baseado em similaridade
A data warehousing environment supports the decision-making process through the investigation and analysis of data in an organized and agile way. However, the current data warehousing technologies do not allow that the decision-making processe be carried out based on images pictorial (intrinsic) features. This analysis can not be carried out in a conventiona
