Introduction: Physical activity in Brazil is assessed by the Telephone-based Risk Factor Surveillance System for Chronic Diseases (VIGITEL). Objectives: To evaluate the reliability and concurrent validity of VIGITEL physical activity indicators. Methods: For the reliability study, 305 individuals responded to VIGITEL interviews, which were repeated with intervals of 7 - 15 days, in Belo Hor...

Recognition of transportation modes can be used in different applications including human behavior research, transport management and traffic control. Previous work on transportation mode recognition has often relied on using multiple sensors or matching Geographic Information System (GIS) information, which is not possible in many cases. In this paper, an approach based on ensemble learning is...

This article considers the two-stage fixed-charge transportation problem which models an important transportation application in a supply chain, from manufacturers to customers through distribution centers. For solving this optimization problem we describe a hybrid algorithm that combines a steady-state genetic algorithm with a local search procedure. The computational results for an often used...

This research was conducted aiming to overcome the problem of effectiveness delivery goods by Cendrawasi Expeditionary Company which at this time still does not use a decision support system approach. For process delivering customers be carried out effectively, is designed that functions determine priority delivered first. solved designing using Simple Additive Weighting (SAW) method serves hel...

In this paper, an improved multi-exposure image fusion method for intelligent transportation systems (ITS) is proposed. Further, a new dataset traffic signs, TrafficSign, presented to verify the method. system, as type of important road information, signs are fused by obtain with moderate brightness and intact information. By estimating degree retention different features in source image, resul...
