Transformation From CIM to PIM: A Systematic Mapping

Model Driven Architecture (MDA) is the most prominent and accepted methodology based on the Model Driven Development (MDD) principles. MDA includes three abstraction levels: Computer Independent Models (CIM), Platform Independent models (PIM) and Platform speci c models (PSM). MDA encourages the automatic transformation of models as a means to increase the speed of the software development process and to prevent human errors. There are plenty of solutions to transform PIMs to PSMs, however the CIM to PIM transformation does not receive a similar attention. In that sense, this paper aims to describe a systematic mapping to analyze the main characteristics of the approaches that deal with the CIM to PIM transformation as well as to discuss research directions stemming out from our analysis. The results of this mapping study could be a valuable information source for the scienti c community in order to know the real advances in this topic and to avoid unnecessary effort dealing with problems that have already been addressed. For example, this study yielded the models at the CIM level that have already been transformed into models at the PIM level. Hence, with this information, the researchers could focus their attention on nding solutions to transform those models at CIM level that have not been transformed into models at PIM level. Likewise, this mapping study provides information regarding the technological support of this type of transformation. This information could be useful for those software projects interested to adopt MDA.Postdoctoral Fellowship through the Institute of Computer Technologies and Information Security, Southern Federal University PD/20-02-K

Coordination of Speech Recognition Devices in Intelligent Environments with Multiple Responsive Devices

Devices with oral interfaces are enabling new interesting interaction scenarios and ways of interaction in ambient intelligence settings. The use of several of such devices in the same environment opens up the possibility to compare the inputs gathered from each one of them and perform a more accurate recognition and processing of user speech. However, the combination of multiple devices presents coordination challenges, as the processing of one voice signal by different speech processing units may result in conflicting outputs and it is necessary to decide which is the most reliable source. This paper presents an approach to rank several sources of spoken input in multi-device environments in order to give preference to the input with the highest estimated quality. The voice signals received by the multiple devices are assessed in terms of their calculated acoustic quality and the reliability of the speech recognition hypotheses produced. After this assessment, each input is assigned a unique score that allows the audio sources to be ranked so as to pick the best to be processed by the system. In order to validate this approach, we have performed an evaluation using a corpus of 4608 audios recorded in a two-room intelligent environment with 24 microphones. The experimental results show that our ranking approach makes it possible to successfully orchestrate an increasing number of acoustic inputs, obtaining better recognition rates than considering a single input, both in clear and noisy settings.This research has received funding by the project DEP2015-70980-R of the Spanish Ministry of Economy and Competitiveness (MINECO) and European Regional Development Fund (ERDF), the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 823907 (‘Mental health monitoring through interactive conversations’, MENHIR Project), as well as, received inputs from the COST Action IC1303 AAPEL

A Model-Driven Approach for Wearable Systems Developments

This paper proposes a model-driven approach for developing high-level software interfaces that allow developers to interact with wearable devices easily. These components hide the heterogeneity of the devices interfaces and provide developers with a simple and homogeneous way to interoperate with these digital peripherals. The use of this approach also allows reducing risks and development efforts.This work has been partially funded by the Facultad de Educación, Economía y Tecnología de Ceuta under the “Contrato-Programa” of research for the period 2013–2015.

Designing a goal-oriented smart-home environment

The final publication is available at Springer via http://dx.doi.org/10.1007/s10796-016-9670-x[EN] Nowadays, systems are growing in power and in access to more resources and services. This situation makes it necessary to provide user-centered systems that act as intelligent assistants. These systems should be able to interact in a natural way with human users and the environment and also be able to take into account user goals and environment information and changes. In this paper, we present an architecture for the design and development of a goal-oriented, self-adaptive, smart-home environment. With this architecture, users are able to interact with the system by expressing their goals which are translated into a set of agent actions in a way that is transparent to the user. This is especially appropriate for environments where ambient intelligence and automatic control are integrated for the user’s welfare. In order to validate this proposal, we designed a prototype based on the proposed architecture for smart-home scenarios. We also performed a set of experiments that shows how the proposed architecture for human-agent interaction increases the number and quality of user goals achieved.This work is partially supported by the Spanish Government through the MINECO/FEDER project TIN2015-65515-C4-1-R.Palanca Cámara, J.; Del Val Noguera, E.; García-Fornes, A.; Billhard, H.; Corchado, JM.; Julian Inglada, VJ.

A Communication Model to Integrate the Request-Response and the Publish-Subscribe Paradigms into Ubiquitous Systems

The Request-Response (RR) paradigm is widely used in ubiquitous systems to exchange information in a secure, reliable and timely manner. Nonetheless, there is also an emerging need for adopting the Publish-Subscribe (PubSub) paradigm in this kind of systems, due to the advantages that this paradigm offers in supporting mobility by means of asynchronous, non-blocking and one-to-many message distribution semantics for event notification. This paper analyzes the strengths and weaknesses of both the RR and PubSub paradigms to support communications in ubiquitous systems and proposes an abstract communication model in order to enable their seamless integration. Thus, developers will be focused on communication semantics and the required quality properties, rather than be concerned about specific communication mechanisms. The aim is to provide developers with abstractions intended to decrease the complexity of integrating different communication paradigms commonly needed in ubiquitous systems. The proposal has been applied to implement a middleware and a real home automation system to show its applicability and benefits.This research work is funded by the Project P10-TIC-6600 granted by the Andalusian Regional Government, and the Project 20F2/36 granted by CEI-BioTIC Granada.

Mapping Utility Scores from a Disease-Specific Quality-of-Life Measure in Bariatric Surgery Patients

AbstractObjectivesTo develop algorithms for a conversion of disease-specific quality-of-life into health state values for morbidly obese patients before or after bariatric surgery.MethodsA total of 893 patients were enrolled in a prospective cross-sectional multicenter study. In addition to demographic and clinical data, health-related quality-of-life (HRQoL) data were collected using the disease-specific Moorehead-Ardelt II questionnaire (MA-II) and two generic questionnaires, the EuroQoL-5D (EQ-5D) and the Short Form-6D (SF-6D). Multiple regression models were constructed to predict EQ-5D- and SF-6D-based utility values from MA-II scores and additional demographic variables.ResultsThe mean body mass index was 39.4, and 591 patients (66%) had already undergone surgery. The average EQ-5D and SF-6D scores were 0.830 and 0.699. The MA-IIwas correlated to both utility measures (Spearman's r = 0.677 and 0.741). Goodness-of-fit was highest (R2 = 0.55 in the validation sample) for the following item-based transformation algorithm: utility (MA-II-based) = 0.4293 + (0.0336 × MA1) + (0.0071 × MA2) + (0.0053 × MA3) + (0.0107 × MA4) + (0.0001 × MA5). This EQ-5D-based mapping algorithm outperformed a similar SF-6D-based algorithm in terms of mean absolute percentage error (P = 0.045).ConclusionsBecause the mapping algorithm estimated utilities with only minor errors, it appears to be a valid method for calculating health state values in cost-utility analyses. The algorithm will help to define the role of bariatric surgery in morbid obesity

Taller de Redacción y Proyectos Periodísticos

Memoria del proyecto de innovación docente Taller de Redacción y Proyectos Periodísticos, concedido en la convocatoria 2017-2018 del Plan Propio de la UCAM.El proyecto de innovación docente denominado “Taller de Redacción y Proyectos Periodísticos” es un diseño experimental para provocar diversas sinergias de producción de contenidos y evaluación entre las asignaturas obligatorias de periodismo “Reportajes y Entrevistas” (segundo curso), “Autoempleo y Proyectos Periodísticos” (tercer curso) y “Taller de Periodismo Multimedia” (cuarto curso). Las tres asignaturas son de primer semestre y con ellas se pretende, al igual que está ocurriendo en el mundo laboral del periodismo, crear una convergencia de redacciones para que el alumno se vea implicado en equipos de trabajo con compañeros de diferente formación, trabajando por objetivos para medios diferentes (dos plataformas digitales con las que ya se trabaja en las asignaturas de tercero y cuarto) y, de este modo, implicar al alumnado en una visión más holística del contenido informativo.PMAFI 2017-2018Ciencias de la Comunicació

Qué y cómo se evalúa en el TFG del Grado en Ingeniería Informática en España

Este trabajo presenta una comparativa sobre cómo se está realizando la evaluación por competencias en la asignatura de Trabajo Fin de Grado (TFG) en los distintos Grados en Ingeniería Informática a nivel nacional. Para ello, se han consultado todas las guías docentes disponibles, las rúbricas y el informe que debe realizar la comisión evaluadora (si los hubiere). En esta contribución se analizan las diferencias y similitudes encontradas. Tras realizar un análisis cualitativo y cuantitativo, se llega a la conclusión de que, actualmente, la evaluación de las competencias asignadas a la asignatura de TFG es un proceso sujeto a subjetividades y que no refleja la gran mayoría de las competencias que se supone que deben ser evaluadas y calificadas.This work presents a comparison study about how competency-based evaluation is being performed in the senior degree project (Trabajo fin de Grado in Spanish) subject in the computing curricula of the Spanish universities. All available teaching guides, evaluation rubrics and the reports (if any) to be delivered by the corresponding evaluation committees have been checked, both quantitatively and qualitatively. The analysis of results yields the conclusion that, at present, the evaluation of competencies for the senior degree Project is a subjective process that does not reflects most of competencies that, in theory, should be assessed and marked.Este proyecto está financiado por la Universidad de Granada, en la convocatoria de Proyectos de Innovación Docente y Buenas Prácticas del Plan FIDO UGR 2022-2023, modalidad de proyectos coordinados: Proyecto “Cómo escribir tu TFG o TFM de ingeniería Informática y no morir en el intento: dificultades, retos y elaboración de materiales docentes.

To access the final edited and published work see https://doi.org/10.1038/s41598-021-92933-2The prevalence of asthma is considerably high among women of childbearing age. Most asthmatic women also often have other atopic disorders. Therefore, the diferentiation between patients with atopic diseases without asthma and asthmatics with coexisting diseases is essential to avoid underdiagnosis of asthma and to design strategies to reduce symptom severity and improve quality of life of patients. Hence, we aimed for the frst time to conduct an analysis of volatile organic compounds in exhaled breath of women of childbearing age as a new approach to discriminate between asthmatics with other coexisting atopic diseases and non-asthmatics (with or without atopic diseases), which could be a helpful tool for more accurate asthma detection and monitoring using a noninvasive technique in the near future. In this study, exhaled air samples of 336 women (training set (n= 211) and validation set (n= 125)) were collected and analyzed by thermal desorption coupled with gas chromatography-mass spectrometry. ASCA (ANOVA (analysis of variance) simultaneous component analysis) and LASSO+LS (least absolute shrinkage and selection operator+ logistic regression) were employed for data analysis. Fifteen statistically signifcant models (p-value< 0.05 in permutation tests) that discriminated asthma with other coexisting atopic diseases in women of childbearing age were generated. Acetone, 2-ethyl-1-hexanol and a tetrahydroisoquinoline derivative were selected as discriminants of asthma with other coexisting atopic diseases. In addition, carbon disulfde, a tetrahydroisoquinoline derivative, 2-ethyl-1-hexanol and decane discriminated asthma disease among patients with other atopic disorders. Results of this study indicate that refned metabolomic analysis of exhaled breath allows asthma with other coexisting atopic diseases discrimination in women of reproductive ag
