Relationship among research collaboration, number of documents and number of citations. A case study in Spanish computer science production in 2000-2009.

This paper analyzes the relationship among research collaboration, number of documents and number of citations of computer science research activity. It analyzes the number of documents and citations and how they vary by number of authors. They are also analyzed (according to author set cardinality) under different circumstances, that is, when documents are written in different types of collaboration, when documents are published in different document types, when documents are published in different computer science subdisciplines, and, finally, when documents are published by journals with different impact factor quartiles. To investigate the above relationships, this paper analyzes the publications listed in the Web of Science and produced by active Spanish university professors between 2000 and 2009, working in the computer science field. Analyzing all documents, we show that the highest percentage of documents are published by three authors, whereas single-authored documents account for the lowest percentage. By number of citations, there is no positive association between the author cardinality and citation impact. Statistical tests show that documents written by two authors receive more citations per document and year than documents published by more authors. In contrast, results do not show statistically significant differences between documents published by two authors and one author. The research findings suggest that international collaboration results on average in publications with higher citation rates than national and institutional collaborations. We also find differences regarding citation rates between journals and conferences, across different computer science subdisciplines and journal quartiles as expected. Finally, our impression is that the collaborative level (number of authors per document) will increase in the coming years, and documents published by three or four authors will be the trend in computer science literature.

Analysis of the discharge capacity of radial-gated spillways using CFD and ANN - Oliana Dam case study.

The paper focuses on the analysis of radial-gated spillways, which is carried out by the solution of a numerical model based on the finite element method (FEM). The Oliana Dam is considered as a case study and the discharge capacity is predicted both by the application of a level-set-based free-surface solver and by the use of traditional empirical formulations. The results of the analysis are then used for training an artificial neural network to allow real-time predictions of the discharge in any situation of energy head and gate opening within the operation range of the reservoir. The comparison of the results obtained with the different methods shows that numerical models such as the FEM can be useful as a predictive tool for the analysis of the hydraulic performance of radial-gated spillways.

Structuring research methods and data with the research object model: genomics workflows as a case study

Background: One of the main challenges for biomedical research lies in the computer-assisted integrative study of large and increasingly complex combinations of data in order to understand molecular mechanisms. The preservation of the materials and methods of such computational experiments with clear annotations is essential for understanding an experiment, and this is increasingly recognized in the bioinformatics community. Our assumption is that offering means of digital, structured aggregation and annotation of the objects of an experiment will provide necessary meta-data for a scientist to understand and recreate the results of an experiment. To support this we explored a model for the semantic description of a workflow-centric Research Object (RO), where an RO is defined as a resource that aggregates other resources, e.g., datasets, software, spreadsheets, text, etc. We applied this model to a case study where we analysed human metabolite variation by workflows. Results: We present the application of the workflow-centric RO model for our bioinformatics case study. Three workflows were produced following recently defined Best Practices for workflow design. By modelling the experiment as an RO, we were able to automatically query the experiment and answer questions such as “which particular data was input to a particular workflow to test a particular hypothesis?”, and “which particular conclusions were drawn from a particular workflow?”. Conclusions: Applying a workflow-centric RO model to aggregate and annotate the resources used in a bioinformatics experiment, allowed us to retrieve the conclusions of the experiment in the context of the driving hypothesis, the executed workflows and their input data. The RO model is an extendable reference model that can be used by other systems as well.

Using the Cross-Entropy Method for Control Optimization: A Case Study of See-and-Avoid on Unmanned Aerial Vehicles

This paper presents an adaptation of the Cross-Entropy (CE) method to optimize fuzzy logic controllers. The CE is a recently developed optimization method based on a general Monte-Carlo approach to combinatorial and continuous multi-extremal optimization and importance sampling. This work shows the application of this optimization method to optimize the inputs gains, the location and size of the different membership functions' sets of each variable, as well as the weight of each rule from the rule's base of a fuzzy logic controller (FLC). The control system approach presented in this work was designed to command the orientation of an unmanned aerial vehicle (UAV) to modify its trajectory for avoiding collisions. An onboard looking forward camera was used to sense the environment of the UAV. The information extracted by the image processing algorithm is the only input of the fuzzy control approach to avoid the collision with a predefined object. Real tests with a quadrotor have been done to corroborate the improved behavior of the optimized controllers at different stages of the optimization process.

Migration and War Memory in a European Perspective A Case-Study on Displaced Persons in Belgium. Natolin Research Paper 05/2011

In the aftermath of World War II, about 20,000 people who had experienced displacement entered Belgium.1 Among those there were about 350 soldiers serving in the Polish armed forces in the West, and about 4,000 ostarbeiterinnen - young female Soviet citizens who were deported to Nazi Germany to do forced labour. All the soldiers and Soviet women married Belgian citizens, and most settled in the home town or city of their spouses. This paper focuses on the war memories of these migrants in post-war life, memories that were arguably shaped not only by the characteristics of their war experiences themselves, but also by the changing positions which they held within their home and host societies. Following the migrants from their moment of settlement until today, the article highlights the changing dynamics of their war memories over time, starting during the Cold War era and ending up in present day Europe. As such, the study finds itself on the crossroads of memory and migration studies, two academic disciplines that only recently started to dialogue with each other.2 Before analysing the arrival, settlement and war memories of the Displaced Persons at study, I give an interpretation of academic literature on memory of World War II from the perspective of migration studies.

Analyser l’influence du syndicalisme agricole majoritaire: quelle utilité pour le modèle néo-corporatiste? Etude de cas à partir du «mini-paquet lait» = Analyze the influence of the majority agricultural trade unionism: what use to the neo-corporatist model? Case study from the "mini-milk package". Bruges Political Research Paper No. 35, August 2014

Cette recherche se propose de réfléchir sur la place des groupes d’intérêts dans le système politique de l’UE en partant de l’exemple de la filière lait. Dans un système généralement pluraliste, la PAC fait en effet figure de cas particulier puisqu’elle a fonctionné à partir des années 1960 sur une logique de co-gestion de la politique des marchés entre la Commission et la principale fédération agricole européenne, le Comité des Organisations Professionnelles agricoles (COPA) associé depuis 1962 au Comité Général de la Coopération agricole de l'Union européenne (COGECA). Néanmoins, du fait du processus de réforme de la PAC engagé depuis 1992, il paraît nécessaire d’analyser si la logique de co-gestion est remise en cause. Cette recherche conclue qu’il existe bien un rapport néo-corporatiste dans le secteur laitier, dans le sens où un acteur en particulier, le syndicat COPA-COGECA est parvenu à influencer de manière déterminante la procédure en obtenant de renforcer le pouvoir de négociation des producteurs sans revenir sur les réformes récentes de la PAC.

EU democratization policies in the Neighbourhood countries and Russia’s reaction as a destabilizing factor. A comparative case study of Georgia and Moldova. Bruges Political Research Papers 45/2015.

The EU democratization policies have not achieved the expected results in Eastern Partnership (EaP) countries. On the contrary, they have led to the outbreak of the most important crisis in Europe after the end of the cold war. A new vision of cooperation in the field of democracy is necessary in the East, as long as even Georgia and Moldova, countries considered to be the most advanced among the EaP states, have not registered essential progress in the democratization of their societies. Assuming that democratization, as part of EU’s neighbourhood policies, can be considered a threat to Russia and hence a ‘destabilizing factor’ for the EU partners, this thesis tried to understand what changes can be made to EU policies and to what extent cooperation between EU and Russia is possible in the process developing democratization policies in Georgia and Moldova. While arguing for the revitalization of the instruments used for the implementation of the democratization policies, this thesis finds that cooperation between the EU and Russia in the field of democracy is excluded as long as the two geo-political actors have different values and different views on the notion of democracy. The most likely cooperation that might occur between EU and Russia is the establishment of a Common Economic Space ‘from Lisbon to Vladivostok’. Even though such a scenario would have the potential to reduce confrontation between the two actors in the common neighbourhood, this cooperation would, however, have a negative impact on the on-going democratic reforms in Georgia and Moldova.
