Mobilizar: Capturing User Behavior with Mobile Digital Diaries

In this paper we present Mobilizar, a web-based mobile tool that facilitates the implementation and data collection of self-reported user behavior. Mobilizar was designed with both the researcher and the participant in mind. It provides investigators with a way to setup a new diary study in a matter of minutes and to electronically collect diary data from participants by using internet-enabled mobile devices. These devices promise to alleviate the burden of carrying a paper-and-pencil diary by instead using the participant’s own device. It also gives participants the flexibility to report their behavior in different ways such as making text, voice, or picture entries that fit their current situational constraints. In this paper, we describe the user interface design of Mobilizar and how it may be used to conduct diary studies with mobile devices

Reengineering of Information Systems toward ClassicalQuantum Systems

In the coming years, companies will progressively need to add quantum computing to some or all of their daily operations. It is clear that all existing, classical information systems cannot be thrown away. Instead of this, it is expected to add some quantum algorithms working embedded in classical information systems. So far, there is not a systematic solution to deal with this challenge. Thus, this talk suggests a software modernization approach (model-driven reengineering) for restructuring classical systems together with existing or new quantum algorithms to provide target systems combining both computational paradigms. The method highlighted is systematic and based on existing software engineering standards (such as KDM and UML). As a result, it could be applied in industry in a compliant manner regarding the existing software evolution processes

A decision-making Support system for Enterprise Architecture Modelling

Companies are increasingly conscious of the importance of Enterprise Architecture (EA) to represent and manage IT and business in a holistic way. EA modelling has become decisive to achieve models that accurately represents behaviour and assets of companies and lead them to make appropriate business decisions. Although EA representations can be manually modelled by experts, automatic EA modelling methods have been proposed to deal with drawbacks of manual modelling, such as error-proneness, time-consumption, slow and poor readaptation, and cost. However, automatic modelling is not effective for the most abstract concepts in EA like strategy or motivational aspects. Thus, companies are demanding hybrid approaches that combines automatic with manual modelling. In this context there are no clear relationships between the input artefacts (and mining techniques) and the target EA viewpoints to be automatically modelled, as well as relationships between the experts' roles and the viewpoints to which they might contribute in manual modelling. Consequently, companies cannot make informed decisions regarding expert assignments in EA modelling projects, nor can they choose appropriate mining techniques and their respective input artefacts. This research proposes a decision support system whose core is a genetic algorithm. The proposal first establishes (based on a previous literature review) the mentioned missing relationships and EA model specifications. Such information is then employed using a genetic algorithm to decide about automatic, manual or hybrid modelling by selecting the most appropriate input artefacts, mining techniques and experts. The genetic algorithm has been optimized so that the system aids EA architects to maximize the accurateness and completeness of EA models while cost (derived from expert assignments and unnecessary automatic generations) are kept under control

Enhanced extended state observer-based control for systems with mismatched uncertainties and disturbances

[EN] This paper presents an enhanced Extended State Observer (ESO)-based control strategy to deal with the disturbance attenuation problem for a class of non integral-chain systems subject to non-linear mismatched uncertainties and external disturbances. The proposed control strategy does not assume the integral-chain form and it is formed by a state-feedback plus a dynamic disturbance compensation term, which is designed to reject the disturbance effect in the system output. From a theoretical point of view, the proposed strategy is reduced to the conventional ESO when the integral chain form and the matched condition hold. In this sense, this paper is presented as an extension of the ESO principles to cover a wider class of systems. The theoretical results show that the internal zero-dynamics plays an important role in ESO-based control design. Also, the closed-loop stability is analyzed and some numerical simulations show the effectiveness of the proposal in comparison with previous ESO-based techniques.This work was partially supported by projects FPU15/02008, FPI-UPV 2014 and TIN2014-56158-C4-4-P-AR, Ministerio de Economia y Competitividad, Spain.Castillo-Frasquet, A.; García Gil, PJ.; Sanz Díaz, R.; Albertos Pérez, P.

Propuestas sobre la enseñanza de la informática cuántica

Estamos asistiendo a una nueva revolución en la que la que los computadores cuánticos empiezan a ser una realidad para resolver problemas difíciles, no resolubles con los actuales computadores “clásicos”. La computación cuántica abre nuevos perfiles profesionales en la informática y aparecen ofertas de trabajo a todos los niveles. Este artículo trata la problemática de que la mayoría de los computing curricula no contemplan este nuevo tipo de paradigma, exceptuando algunos pocos planes de estudios y cursos de tipo MOOC (Massive Online Open Courses) ya ofrecen cierta formación en computación cuántica. En este artículo se presenta un análisis de la situación actual y se propone la inclusión de la materia de Informática Cuántica (y sus correspondientes asignaturas) en los planes de estudio de Ingeniería Informática.We are immersed in a new revolution in which quantum computers have become a real as these can solve difficult problems, not solvable with the current "classic" computers. Quantum computing opens up new professional profiles and roles in computer science, with many job positions offered at different levels. The problem addressed by this paper lies in the fact that most of the computing curricula do not reflect this change since these curricula do not encompass this new type of computation paradigm. Exceptionally, only some few curricula and MOOC courses (Massive Online Open Courses) already offer some training in quantum computing. This article presents an analysis of the current situation and proposes the inclusion of the subject of Quantum Computing in the Computer Engineering curricula.Este trabajo ha sido soportado por los proyectos BIZDEVOPS-Global (RTI2018-098309-B-C31) y ECLIPSE (RTI2018-094283-B-C31) financiados por el Ministerio de Economía, Industria y Competitividad (MINECO) & Fondo Europeo de Desarrollo Regional (FEDER)

A new species of Trachymyrmex (Hymenoptera, Formicidae) fungus-growing ant from the Sierra Madre Oriental of northeastern Mexico

Here we describe a new species of Trachymyrmex, T. pakawa sp. n., from the Gran Sierra Plegada range of the Sierra Madre Oriental, in the states of Coahuila and Nuevo Leon, northeastern Mexico. Trachymyrmex pakawa is a large-sized species compared to other North American Trachymyrmex. Its geographic distribution includes the piedmont of the Gran Sierra Plegada at La Estanzuela, Monterrey, as well as peripheral mountains segregated from the Sierra Madre Oriental (Cerro de las Mitras, Sierra de Zapalinamé, Cañon de San Lorenzo, Cerro de las Letras). The preferred habitats of T. pakawa include oak-pine forest at La Estanzuela, xeric oak forest at Zapalinamé and mesic Chihuahuan desert scrub with sotol (Dasylirion) at other sites. All localities are on slopes, on very rocky, shallow lithosols overlaying large boulders. This species nests under and between large boulders and rocks. It has not been observed on alluvial or better developed, deeper soils, and it is absent from sites with human activity (urban, disturbed, and landscaped areas). It is closely related to and morphologically similar to Trachymyrmex smithi. The known distribution ranges of T. pakawa and T. smithi almost overlap in Saltillo, Coahuila state. The main character that distinguishes the new species from T. smithi is longer antennal scapes in T. pakawa; also, different nesting habits (rocky slopes vs. alluvial sites or deep sand in T. smithi), and geographic distribution. Phylogenetic analysis of DNA sequences from the mitochondrial marker cytochrome c oxidase subunit I (COI) and the first intron of the F1 copy of the nuclear protein-coding gene Elongation Factor 1- α (EF1-α-F1) confirm a sister-species relationship between T. pakawa and T. smithi. Bayesian coalescent analyses indicate a divergence time of about 8.00 million years before present (95% confidence interval: 4.8–11.5 mya) between T. pakawa and T. smithi. The divergence of the lineages of T. pakawa and T. smithi could have been driven by the Pliocene-Holocene desertification of southwestern North America. This process resulted in isolated mesic refugia and forests in the Madrean ranges and piedmonts of northeastern Mexico (the current habitat of T. pakawa) while T. smithi adapted to the deeper, often sandy soils on the drier desert plains of Coahuila and Chihuahua states in Mexico, and New Mexico and Texas in the USA. Within the Nearctic species of the Trachymyrmex septentrionalis species group, T. pakawa is the species that is closest (by geographical distribution) to Neotropical species of Trachymyrmex like T. saussurei

Mainframe Migration based on Screen Scraping

Companies possess a history and large array of legacy information systems that consume a great part of their IT budget in operations and maintenance. These systems are mission-critical, and they cannot be fully discarded since they retain business rules and provide information that is not available anywhere else. Unfortunately, decades-old legacy systems cannot easily withstand modification. Mainframes specifically conglomerate most of these legacy systems. Although there are some white-box solutions for migrating mainframe systems, such solutions lack systematicity and do not provide mechanisms for verifying business rules preservation. Hence, this paper presents a black-box solution (ignoring the internal structure of COBOL programs) which uses a screen scraping technique for migrating mainframe systems toward JavaFX and relational databases. Together with this solution, this paper provides an automatic verification technique to check if the recreated system reflects all the embedded business logic. This proposal has been designed and developed in the context of an industrial project, in which the solution has already migrated 43,000,000 mainframe screens from four systems. The main implication for researchers and practitioners is that screen scraping has proved to be feasible for migrating mainframe systems in large-scale projects within a manageable time-frame while preserving business
