The design of lightweight block ciphers has been a very active research topic over the last years. However, the lack of comparative source codes generally makes it hard to evaluate the extent to which different ciphers actually reach their low-cost goals, on different platforms. This paper reports on an initiative aimed to partially relax this issue. First, we implemented 11 block ciphers on an...

La Biblioteca Virtual Miguel de Cervantes (BVMC) ha desarrollado una aplicación basada en MASTER (Manuscript Access through Standards for Electronic Records), para el proyecto Manuscritos de América en las Colecciones Reales de la Real Biblioteca (Madrid). Con este proyecto se pretende unificar recursos de descripción bibliográfica aplicada a manuscritos añadiendo el acceso al documento en form...

Feature refactoring is the process of decomposing a system's code into a set of modules, called features, that are a means for communicating commonalities and variabilities to stakeholders. As features encapsulate functionality, different compositions of features yield a family of different systems. Previous work describes how feature decomposition is done manually at source code level, it bein...

Background Avante Zambéziais an initiative of a Non-Governmental Organization (NGO), Friends in Global Health, LLC (FGH) and the Vanderbilt Institute for Global Health (VIGH) to provide technical assistance to the Mozambican Ministry of Health (MoH) in rural Zambézia Province.

company to afford the service requestor with the expressed need. Due to the increasing importance of service offerings as a revenue source and increasing competition among service providers, it is important for companies to optimize both the customer experience as well as the associated cost of providing the service. For more complex interactions with higher value, mixed-initiative systems prov...

The OGC Web Processing Service specification provides a means to perform web-based processes on distributed geodata and to produce thereby web-based geoinformation. However a client which integrates different data and geo-processing services is missing but would enable fully web-based information integration. This was the starting point for this study to build a client, which is able to integra...

This paper presents GnuTutor, an open source intelligent tutoring system (ITS) inspired by the AutoTutor ITS. The goal of GnuTutor is to create a freely available, open source ITS platform that can be used by schools and researchers alike. To achieve this goal, significant departures from AutoTutor’s current design were made so that GnuTutor would use a smaller, non-proprietary code base but ha...

A major source of interoperability problems on the Semantic Web are the different vocabularies used in metadata descriptions. This paper argues that instead of solving interoperability problems we should focus more effort on avoiding the problems in the first place, in the spirit of Albert Einstein's quote "Intellectuals solve problems, geniuses prevent them". For this purpose, coordinated coll...

This paper presents our work on grapheme based crosslingual speech recognition carried out within the MASPER initiative. The performance of monolingual grapheme based acoustic models is compared to the performance of monolingual acoustic models based on phonemes. The transfer between source and target language was done using an expert knowledge approach. For the experiments, German, Spanish, Hu...

With ever-increasing amounts of metabolomics data produced each year, there is an even greater need to disseminate data and knowledge produced in a standard and reproducible way. To assist with this a general purpose, open source metabolomics repository, MetaboLights, was launched in 2012. To promote a community standard, initially culminated as metabolomics standards initiative (MSI), COordina...
