Three-Dimensional (3D) technologies emerged from the technological advances in manufacturing required to produce physical versions of digital models. The most attractive feature of 3D technologies is that virtual models ...

In Ubiquitous Computing, augmented objects refer to those elements of the real world which have been provided with computational capabilities to meet a specific need. Meanwhile, Collaborative Writing Environments (CWE) ...

Awareness could be defined as the knowledge that the user has of a particular activity, either individual or collaborative. Good awareness mechanisms provide information to the user at the right time so that s/he can know ...

This paper presents the evolution of an undergraduate microcontroller’s course that uses Arduino as its main platform. In earlier versions of the course, it focused on teaching Arduino’s framework and its interconnection ...

Program visualizations help students understand the runtime behavior of other programs. They are educational tools to complement lectures or replace inefficient static drawings. A recent survey found 46 program ...

We focus on the discussion about the proposal of shifting to a post paid mobile Internet tariff model based on usage, and its impact on universal use and service access for the poor sectors of the country. This proposal ...

This paper provides an overview of a doctoral research project which focuses in developing a framework to allow smart device-based notifications to provide user awareness. Notifications are mechanisms by which the user’s ...

The use of smart devices is increasing rapidly; this trend is changing the paradigm in which notifications are delivered to users. Smart devices are important to provide user awareness. However, their use must be controlled ...

Technological applications have an increasingly important role in most companies. Investment in Information Technologies (IT) is also growing in most of them. The need to align IT-related goals with the company’s strategic ...

The objective of this work is to detect Alzheimer’s disease using Magnetic Resonance Imaging. For this, we use a three-dimensional densenet-121 architecture. With the use of only freely available tools, we obtain good ...
