1. The electric boat charging problem
Abstract Paper aims This paper studies a new optimization problem called the Electric Boat Charging Problem (EBCP), which is based on the application of electric mobility in a river transport operation problem. Originality This work pioneers the studies of the electric mobility on the river operations, by proposing the EBCP. This problem includes real feat

2. NUMERICAL AND COMPUTATIONAL ASPECTS OF COSMO-BASED ACTIVITY COEFFICIENT MODELS
ABSTRACT In the present work, some numerical and computational aspects of COSMO-based activity coefficient models were explored. The residual contribution in such models rely on the so called self-consistency equation. This equation does not have a closed-form solution and is usually solved by the successive substitution method. The performance of a classica

3. Selection of a Hyper-Elastic Material Model - a Case Study for a Polyurethane Component
Abstract The aim of this study was to select an appropriate material model for a polyurethane rail pad. The considered material was assumed to be hyper-elastic, and model selection was limited only to the Mooney-Rivlin (M-R) material models available in the MSC.Marc/Mentat system. The selection of the most appropriate material model was based on the most acc

5. Ocupação de conchas pelo ermitão Dardanus insignis na costa norte do estado de São Paulo, Brasil
Resumo O padrão de ocupação de conchas pelo ermitão D. insignis (Saussure, 1858) na região subtropical da costa sudeste do Brasil, foi investigada no presente estudo. Foram analisadas a percentual de tipos de conchas que foram ocupados e as relações morfométricas entre os ermitões e conchas ocupadas, a partir de coletas mensais realizadas durante do

6. Polydrug use among college students in Brazil: a nationwide survey
Objective: To estimate the frequency of polydrug use (alcohol and illicit drugs) among college students and its associations with gender and age group. Methods: A nationwide sample of 12,544 college students was asked to complete a questionnaire on their use of drugs according to three time parameters (lifetime, past 12 months, and last 30 days). The co-u

7. Uma aplicação de redes definidas por software para a gerência de redes de datacenters virtualizados
Cloud-Computing services related to infrastructure have been drawing much attention recently. On this business model, virtualization is an efficient way to ofier flexibility, isolation and several new functionalities. This technology has led to the multi-tenant datacenter model for Cloud-Computing, where the client (tenant) can rent not only a virtual machin

8. FairCPU: Uma Arquitetura para Provisionamento de MÃquinas Virtuais Utilizando CaracterÃsticas de Processamento / FairCPU: An Architecture for Provisioning Virtual Machines Using Processing Features
Resource scheduling is a key process for cloud computing platform, which generally uses virtual machines (VMs) as scheduling units. The use of virtualization techniques provides great flexibility with the ability to instantiate multiple VMs on one physical machine (PM), migrate them between the PMs and dynamically scale VMâs resources. The techniques of con

9. A study on the extension of an upwind parallel solver for turbulent flow applications
The present work is primarily concerned with studying the influence of an upwind spatial discretization on the capability of representing turbulent flows on aerospace applications, in the context of a flow simulation code that is fairly close to a production code. Therefore, the work addresses the issues of implementing and validating an advanced turbulence
