Virtual learning environments are actual solutions that facilitate collaborative learning, both in classroom and distance education. However, such environments are not yet fully disseminated in Brazilian universities. This work reports a learning experience designed as a workshop that aims to popularize the use of the Canvas virtual learning environment in an university. The workshop emphasizes...

Background: In this paper we describe a configurable system based on laser displacement sensors for the contactless acquisition of 3D and 2D shapes of near-planar objects such as the paintings. Methods: The system is based on two single-point laser triangulation sensors, a planar robot and a suite of software for driving the sensors, acquiring and post-processing the collected data. As a demons...

Graphical notations have traditionally played an important role in the process of software development, particularly during the analysis and design phases. However, in applications in which the reliability of the software is a primary concern a graphical notation such as UML needs to be complemented by a formal language in order to provide enhanced support for pragmatic and rigorous development...

Massive actuator arrays found their applications in robotics, pharmaceutics, aerospace, etc. Compared with electrically and/or pneumatically powered actuator array, hydraulic actuator has the comprehensive advantages of higher force density (i.e. force / actuation area), better controllability, and simpler remote control accessibility. This paper presents approaches to construct and control a m...
