One of the problems for archaeologic museums is having the opportunity to show most of the objects that they preserve. This is an action they can’t afford because of the limitation of exhibition spaces, the high number of artifacts they guard and/or the conditions of the real objects. Nowadays, with the use of cutting-edge 3D technologies, there is...
p>Advances in three-dimensional (3D) acquisition systems have introduced this technology to more fields of study, such as archaeology or architecture. In the architectural field, scanning a building is one of the first possible steps from which a 3D model can be obtained and can be later used for visualisation and/or feature analysis, thanks to com...

In order to avoid the gap between the post-compulsory secondary education and the University, the PATU program has been conducted at the UPV. Every freshman has a teacher as an academic advisor and a sophomore as an “older brother”. Students have evaluated the program as useful and interesting, and in addition, the ones following this action have a...
Mathematics is an important core of the syllabus of any Computer Science degree. We have studied the relation between the learning competence of Mathematics for first-years at the Universidad Politécnica de Valencia, and their success in the subjects of mathematics in the degree. Its relevance for their success in the whole first academic year is a...
Nowadays, one of the main problems we have to face as teachers is the current profile of the students. In some sense, today's students are indifferent to traditional teaching methodologies, and they seem to expect new ways to acquire knowledge. For that reason, an important amount of students starting university studies have a passive attitude when...

When a higher education institution creates a new curriculum for a given degree, the design process itself ensures a correct balance and coordination among the subjects in the degree, not only about the contents and learning outcomes of each subject, but also in the learning weight of all the subjects in each semester. However, it is common that, a...
ROC Curves (Receiver Operating Characteris- tic) are remarkably useful in medical decision-making. Given a common measurable characteristic, with a con- tinuous output in all the beings of a group, ROC curves determine a threshold on the values of the characteristic, which tries to predict the classification of beings into dis- crete classes. In th...

The VirtualRobot (VRS) is a 3D graphical robot simulator. In this simulator the construction of 3D environments are based on either a graphical editor or on a script file using a set of primitives and their compositions, which are loaded and vi-sualized by the VRS. This procedure is time con-suming and requires a good acquaintance with the set of p...
One of the current topics of research in robotics is activity planning. Most works in this field are related to artificial intelligence (AI) techniques. The main feature of robot planning systems is that they are focused on the particular robot problem or are intended to solve a particular aspect of the planning problem. For this last case, motion...
In a manufacturing environment, material transport plays a key role for the production process efficiency. In Schoeller-Bregenz (SB), a textile manufacturing SME, induction wire guided vehicles performed typical material transports, without the flexibility to adapt transport routes to changes in the production process. To overcome these deficits in...

The standardised use of local area networks (LANs), together with the power of available computers has significantly reduced communications difficulties. The next key challenge to be addressed is...
Considering dynamic environments where mobile robots move makes much more difficult planning resolution. The possibility to have non-controlled mobiles in the environment is one of the cases considered in dynamic environments.
Most of mobile robots in industrial environments are wire guided, following induction wires and artificial reference marks laid down on the factory floor. This kind of approach has the lack of flexibility to adapt the system for different transport requirements. This lack may be overcome using Autonomous Guided Vehicles (AGVs) which must be provide...
At the moment, the common implementation of local area networks
allows working in a total communicative environment. Taking advantage of
this fact, and the facility to establish communication with a robotized
system, one logical step is to join both to get maximum performance. The
integration of a robotized system with a local area network is
prese...
