A low cost and widely applicable methodology of digital imagen analysis of ores for mineral and envirommental engineering

Technological and environmental problems related to ore processing are a serious limitation for sustainable development of mineral resources, particularly for countries / companies rich in ores, but with little access to sophisticated technology, e.g. in Latin America. Digital image analysis (DIA) can provide a simple, unexpensive and broadly applicable methodology to assess these problems, but this methodology has to be carefully defined, to produce reproducible and relevant information.

Combining data mining and ontology engineering to enrich ontologies and linked data

In this position paper, we claim that the need for time consuming data preparation and result interpretation tasks in knowledge discovery, as well as for costly expert consultation and consensus building activities required for ontology building can be reduced through exploiting the interplay of data mining and ontology engineering. The aim is to obtain in a semi-automatic way new knowledge from distributed data sources that can be used for inference and reasoning, as well as to guide the extraction of further knowledge from these data sources. The proposed approach is based on the creation of a novel knowledge discovery method relying on the combination, through an iterative ?feedbackloop?, of (a) data mining techniques to make emerge implicit models from data and (b) pattern-based ontology engineering to capture these models in reusable, conceptual and inferable artefacts.

El programa ERHIN y la gestión de embalses en áreas con alta precipitación nival = The ERHIN programme and reservoir management in areas of high nival precipitation

El programa de Evaluación Recursos Hídricos procedentes de la Innivación (ERHIN) ha desarrollado un modelo hidrológico con subrutinas que contemplan el proceso de acumulación/fusión de nieve que permite el seguimiento del manto de nieve y su fusión , esencial para la previsión de avenidas en embalses cuyas cuencas vertientes recogen altos porcentajes de precipitación solida. En determinados sectores del territorio español (Pirineos, Cordilleras Cantábrica e Ibérica, Sistema Central y Sierra Nevada) la precipitación nival alcanza valores significativos durante el invierno, que conducen a espesores de nieve persistentes en las cuencas alimentadoras de numerosos embalses y a la fusión rápida de esta nieve en períodos cortos de tiempo, directamente relacionados con la elevación de la isoterma de cero grados en primavera. Estos procesos condicionan la gestión de los mencionados embalses.

Emotions and the Engineering of Adaptiveness in Complex Systems

A major challenge in the engineering of complex and critical systems is the management of change, both in the system and in its operational environment. Due to the growing of complexity in systems, new approaches on autonomy must be able to detect critical changes and avoid their progress towards undesirable states. We are searching for methods to build systems that can tune the adaptability protocols. New mechanisms that use system-wellness requirements to reduce the influence of the outer domain and transfer the control of uncertainly to the inner one. Under the view of cognitive systems, biological emotions suggests a strategy to configure value-based systems to use semantic self-representations of the state. A method inspired by emotion theories to causally connect to the inner domain of the system and its objectives of wellness, focusing on dynamically adapting the system to avoid the progress of critical states. This method shall endow the system with a transversal mechanism to monitor its inner processes, detecting critical states and managing its adaptivity in order to maintain the wellness goals. The paper describes the current vision produced by this work-in-progress.

Paul–Straubel–Kingdon trap for true zero-point confinement of an individual ion and reservoir

A modification of the Paul–Straubel trap previously described by us may profitably be operated in a Paul–Straubel–Kingdon (PSK) mode during the initial loading of an individual ion into the trap. Thereby the coating of the trap ring electrode by the atomic beam directed upon it in earlier experiments is eliminated, as is the ionization of an already trapped ion. Coating created serious problems as it spot-wise changed the work function of the ring electrode, which caused large, uncontrolled dc fields in the trap center that prevented zero-point confinement. Operating the Paul–Straubel trap with a small negative bias on the ring electrode wire is all that is required to realize the PSK mode. In this mode the tiny ring trap in the center of the long, straight wire section is surrounded by a second trapping well shaped like a long, thin-walled cylindrical shell and extending to the end-caps. There, ions may be conveniently created in this well without danger of coating the ring with barium. In addition, the long second well is useful as a multi-ion reservoir.

The Rueter-Hess Dam and Reservoir Project: A Question of Sustainable Water

Water in sufficient quantities throughout the Colorado Front Range is becoming increasingly limited. This paper examines the consequences for continued unsustainable use of water for communities of the Denver metropolitan area. This paper also looks at the effect that water law in the West has for otherwise optimum distributions of water. In addition, four regional and state water studies are reviewed for their contribution to sustainable water. Finally, the Final Environmental Impact Statement of the Rueter-Hess dam and reservoir project in Parker, Colorado is explored. Key findings conclude that the Rueter-Hess project may not, by itself, provide sustainable water for Parker; but the project will create incentive and opportunity for communities throughout the region to address the question of sustainable water.

Differences between the personal, social and emotional profiles of teaching and computer engineering professionals and students

The evidence suggests that emotional intelligence and personality traits are important qualities that workers need in order to successfully exercise a profession. This article assumes that the main purpose of universities is to promote employment by providing an education that facilitates the acquisition of abilities, skills, competencies and values. In this study, the emotional intelligence and personality profiles of two groups of Spanish students studying degrees in two different academic disciplines – computer engineering and teacher training – were analysed and compared. In addition, the skills forming part of the emotional intelligence and personality traits required by professionals (computer engineers and teachers) in their work were studied, and the profiles obtained for the students were compared with those identified by the professionals in each field. Results revealed significant differences between the profiles of the two groups of students, with the teacher training students scoring higher on interpersonal skills; differences were also found between professionals and students for most competencies, with professionals in both fields demanding more competencies that those evidenced by graduates. The implications of these results for the incorporation of generic social, emotional and personal competencies into the university curriculum are discussed.
