Modelling nanoscale fluid dynamics and transport in physiological flows
1996
The concept of nanotechnology is discussed, and its connection with biomedical engineering is elucidated. For the specific field of nanoscale flow and transport problems of physiological relevance, some typical examples are presented, and their interaction is discussed for some classic biomechanical problems like the flow in arteries with blood-wall coupling. Then, existing computational models are presented and classified according to the length scale of interest, with emphasis on particle-fluid problems. Final remarks address the essential unity of biomedical and engineering behaviour and the possible relevance to small-scale industrial research.
SILKNOW. Designing a thesaurus about historical silk for small and medium-sized textile museums
2019
El ámbito del patrimonio cultural en general, y el de los textiles de seda en particular, se caracterizan por conjuntos de datos amplios, ricos y heterogéneos. El vocabulario del patrimonio de la seda procede de múltiples fuentes que se han mezclado a través del tiempo y el espacio. Esto ha llevado a la utilización de diferentes terminología en organizaciones especializadas para describir sus artefactos. Esto hace que los datos interoperabilidad de los datos entre catálogos independientes. Además, el nivel de interacción de los recursos existentes es bajo, la mayoría de las consultas complejas no son posibles y los resultados se muestran de forma deficiente. En En este sentido, un reciente …
Energy and CO2 life cycle inventory issues for aluminum based components: The case study of a high speed train window panel
2016
Abstract As materials production and transport are two relevant sectors in terms of global environmental impact, over the last years environmental impact analyses (mainly life cycle based analyses) of material replacing strategies in means of transportation were developed. Life cycle approach allows to consider the light-weighing benefit without neglecting the environmental impact of material production. In the present research energy and CO2 emissions life cycle analysis of a real case study is presented. Industrial data, experimental measurements and literature analysis were used to develop the life cycle analysis of an aluminum window panel to be assembled on an Italian high speed train.…
Analysing the conceptions on modelling of engineering undergraduate students: A case study using cluster analysis
2016
The problem of taking a set of data and separating it into subgroups where the elements of each subgroup are more similar to each other than they are to elements not in the subgroup has been extensively studied through the statistical method of Cluster Analysis . This method can be conveniently used to separate students into groups that can be recognized and characterized by common traits in their answers, without any prior knowledge of what form those groups would take (unsupervised classification). In the last years many studies examined the consistency of students’ answers in a variety of situations. Some of these papers have tried to develop more detailed models of the consistency of st…
The relevance of the design characteristics to the optimal operation of wastewater treatment plants: Energy cost assessment
2018
Operational parameters of the wastewater treatment process do not always fit the design ones for several reasons, such as the seasonality or an inaccurate estimation of the population connected. This fact has an effect on the performance of the Wastewater Treatment Plants (WWTPs) and their energy costs. The aim of this paper is to develop a cost function for the energy cost that takes into account the mismatching between the design and the operational inflow. For this purpose, a performance index is constructed in order to represent how far the operational inflow is from the design one, and will be included in the cost model. Moreover, three cost functions, depending on the size of the plan…
Introducing the Study of Nordic Cooperation
2020
To rediscover Nordic cooperation this article develops a ‘conceptual grammar’ that provides general theoretical ‘images’ of cooperation that are systematically applied. Being supplementary analytical constructs, moreover, these images capture great variety and differentiation in Nordic cooperation. Next, this article provides a review of two sets of literature that are of particular relevance to this thematic issue. The first is a broader literature on European integration. The second is studies of Nordic cooperation. The article closes with an overview of the contributions to this thematic issue.
Evaluation of Inciso: A system for automatic elaboration of a Citation Index in Social Science Spanish Journal
2007
We have developed a system that can elaborate a citation index in an automated way. It has been tested with Spanish journals. We need evaluate our system, mainly in effectiveness of the retrieval of citations. Criteria for evaluation of the system is presented and discussed, and the results of the application to our system are showed and analyzed.
Notice of Violation of IEEE Publication Principles: Distributed Multimedia Digital Libraries on Peer-to-Peer Networks
2007
This paper presents an original approach to image sharing in large, distributed digital libraries, in which a user is able to interactively search interesting resources by means of content-based image retrieval techniques. The approach described here addresses the issues arising when the content is managed through a peer-to-peer architecture. In this case, the retrieval facilities are likely to be limited to queries based on unique identifiers or small sets of keywords, which may be quite inadequate, so we propose a novel algorithm for routing user queries that exploits compact representations of multimedia resources shared by each peer in order to dynamically adapt the network topology to …
Genre-adaptive Semantic Computing and Audio-based Modelling for Music Mood Annotation
2016
This study investigates whether taking genre into account is beneficial for automatic music mood annotation in terms of core affects valence, arousal, and tension, as well as several other mood scales. Novel techniques employing genre-adaptive semantic computing and audio-based modelling are proposed. A technique called the ACTwg employs genre-adaptive semantic computing of mood-related social tags, whereas ACTwg-SLPwg combines semantic computing and audio-based modelling, both in a genre-adaptive manner. The proposed techniques are experimentally evaluated at predicting listener ratings related to a set of 600 popular music tracks spanning multiple genres. The results show that ACTwg outpe…
WORDY: a Semi-automatic Methodology aimed at the Creation of Neologisms based on a Semantic Network and Blending Devices
2017
In this paper, we propose a semi-automatic tool, named WORDY, that implements a methodology aimed at speeding-up the pro- cess of creation of neologisms. The approach exploits a semantic network, which is explored through the spreading activation methodology and ex- ploits three blending linguistic techniques together with a proper ranking function in order to support companies in the creation of neologisms ca- pable of evoking semantic meaningful associations to customers.
