1. Modeling and Computer Simulation of Viscoelastic Crypt Deformation
ABSTRACT Colorectal cancer morphogenesis begins at the cellular level from cell mutations in the intestinal epithelium cavities called crypts. These mutations lead to a pressure difference in the epithelium crypt walls, which can cause deformation and generate visible abnormalities in the epithelium. The geometrical modeling of these crypts and the mathemati

2. Comparison of ultrasonography learning between distance teaching and traditional methodology. An educational systematic review
ABSTRACT BACKGROUND: Use of the web for radiological education is an obvious application. Many computer-based teaching materials have been developed over recent years, and e-learning is becoming increasingly popular in medical schools. OBJECTIVE: To assess whether the effectiveness of distance-learning and/or e-learning, m-learning and web-based methods ar

3. A DISCRETE STOCHASTIC MODEL TO DETERMINE FOOD QUALITY BY USING SIMULATION: A STRAWBERRY CASE STUDY
ABSTRACT The agri-food supply chain (AFSC) sets a series of challenges in the production, storage, distribution, and transportation processes, as the market's requirements for fresh food combine food quality and safety attributes. This research suggests a discrete event modeling to study the behavior of food quality in all supply chains (SCs) in terms of tem

4. Electromagnetic Energy Harvesting Using a Glass Window
Abstract In this work, a new constructive and conceptual model for rectenna, using glass as dielectric substrate, was proposed. This research aims to produce a window for building facades that can harvest the electromagnetic energy available in the environment. For this proposal, a slotted patch antenna was designed with two main objectives: to have a low va

5. Influences of the mesh in the CAE simulation for plastic injection molding
Abstract Although computer-aided engineering (CAE) software has been used for many years in the plastic industry, identifying the most appropriate mesh geometry and density remains a challenge. It can affect the accuracy of the simulation, the time and the costs. The evaluation of the most suitable mesh is not easy because the difficulties to obtain the real

6. Simulador didático para análise dos transientes de ondas de tensão em uma linha de transmissão similar à transmissão e reflexão de ondas eletromagnéticas
Abstract O modelo de educação nas últimas décadas passou por mudanças consideráveis do ponto de vista didático. Com o avanço da tecnologia, a velocidade de obtenção de informações aumenta e o uso de ferramentas que permitem a visualização dinâmica de conteúdos torna-se um forte aliado ao processo de ensino-aprendizagem. Este trabalho trata da

7. Generalizing Ellipsoidal Growth
This paper generalizes previous work of Rios and Villa on spherical growth. The generalized equation applies to nucleation of ellipsoids according to an inhomogeneous Poisson point process. Microstructural evolution in three dimensions of nucleation and growth transformations of ellipsoids is simulated using the causal cone method. In the simulation, nuclei

9. ESTABLISHMENT OF QUALITY CLASSES FOR HARDWOOD FLOORINGS BY SIMULATED USE
ABSTRACT Many wood species have been employed as floorings, however their performance can vary greatly according to the wood properties and the type of application. Mechanical tests can be performed for simulating the wood floorings in service, but there are no standards for sorting the materials according to their quality as flooring. In this study, the tes

11. Diseño y Evaluación de una Trayectoria Hipotética de Aprendizaje para Intervalos de Confianza basada en Simulación y Datos Reales
Abstract This article discusses the design of a hypothetical learning trajectory to introduce the confidence intervals in a basic university course, from an informal perspective based on the use of data obtained from surveys and samples simulation. The trajectory consists of four activities and was evaluated as part of a first improvement cycle with a group

12. Influence of film coefficient during multicomponent diffusion – KCl/NaCl in biosolid for static and agitated system using 3D computational simulation
Abstract The influence of film coefficient formed during the diffusion of inorganic salts (NaCl and KCl) in biosolids was studied using a 3D computer modeling by Finite Elements Method (FEM) in COMSOL Multiphysics® software combined with SOM-type Artificial Neural Networks (ANN). Such tools have shown that the influence of the film formed in the biosolid/s
