Abstract

Nowadays we consider as new technologies computer appliances (machines and programmes) to the different knowledge areas and the different human activities. From large scientific investigation programmes to videogames, our society has quickly changed with the introduction of computers [...]

Abstract

This paper presents design thinking as an alternative approach to conduct research on collaborative learning with technology. The underlying premise of the paper is the need to adopt human-centered design principles in research and design of computer-supported collaborative tools. [...]

Abstract

We derive analytical relationships between the spatial covariance of the (natural) logarithm of hydraulic conductivity (K) and that of representative [...]

Abstract

In this paper, a new three-level boost converter with continuous input current, common ground, reduced voltage stress on the power switches, and wide voltage gain range is proposed. The proposed converter is composed of a three-level flying-capacitor switching cell and an integrated [...]

Abstract

Remote usability testing tools are very valuable and useful in the design and management of usability tests. These tools can help simplify and streamline our processes. We describe the tool “Loop11” in detail and offer comments on what we learned from our experience with it in [...]

Abstract

We report on a first field test in which miniaturized sensor motes were used to explore and inspect an operational pipeline by performing in situ measurements. The spherical sensor motes with a diameter of 39 mm were equipped with an inertial measurement unit (IMU) measuring 3-D [...]
