Chapter
There are numerous forms of applied coursework in higher education, one of them being Service-Learning—a teaching approach that promotes social responsibility of students. In this study, we investigate the perspectives of teachers on Service-Learning, since there is extensive research about students’ perspectives, but those of teachers are relative...

COVID-19 has brought up new and urgent needs, some of which can be faced through Service-Learning projects, as solidarity is central. We believe that through Service-Learning we can contribute to confronting and overcoming this common threat and its repercussions. For that, we have to design Service-Learning projects that respond to such needs. At...

La "dimensión social de la Educación Superior", pasó de no estar específicamente descrita en la génesis de la Declaración Ministerial de Bolonia (1999) a partir de la que se creó el Área de Educación Superior Europea, a convertirse en un tema central de las Declaraciones posteriores. En ellas se reconoció la importante influencia que las institucio...

In this paper we present a neural network based approach for TCAD empirical modeling. We develop a neural interpolator with a multi-layered feed-forward structure for building empirical models based on a set of experimental/simulated data. We assess the neural interpolator performances on modeling the transport parameters for bulk InxGa1-xAs.

In this paper we discuss some of the existing response surface modeling techniques currently used for TCAD purposes and bring to the readers' attention a Bayesian framework for training feed-forward neural networks. We assess the model performances of different models by studying a 0.25 μm nMOS transistor. We show that the Bayesian learning neural...

A complete description for early resistance change and mechanical stress evolution in near-bamboo interconnects, related to the electromigration, is given in this paper. The proposed model, for the first time, combines the stress/vacancy concentration evolution with the early resistance change of the Al line with a near-bamboo microstructure, which...
Conference Paper
The operation of dual-collector vertical bipolar magnetotransistors (VMT) is analysed using the 2D process/device simulator TRENDY. This way insight in the device behaviour can be obtained by means of the internal distribution of all variables that are not accessible to experiments. By variation of device geometry, doping profile and terminal volta...

Conference Paper
Due to the continuing downscaling of the dimensions in VLSI circuits, electromigration is becoming a serious reliability hazard. A software tool based on finite element analysis has been developed to solve the two partial differential equations of the two particle vacancy/imperfection model. Simulation results of the complex grain structure of Al t...

The ENGAGE STUDENTS project focuses on social responsibility of higher education institutions at students and teachers level. Strengthening the social dimension in education has been an important European priority, that has been accentuated even further by the Commission in the renewed EU agenda for Higher Education. Innovative curricula and teaching approaches are seen to contribute to reduce the current high skills gap between students and labour market needs. The project explores perspectives of teachers in higher education with applied course work and service learning - how, why, and under which conditions do teachers apply the service learning approach or other forms of applied course work?
