Model Based Development of Quality-Aware Software Services

Modelling languages and development frameworks give support for functional and structural description of software architectures. But quality-aware applications require languages which allow expressing QoS as a first-class concept during architecture design and service composition, and to extend existing tools and infrastructures adding support for modelling, evaluating, managing and monitoring QoS aspects. In addition to its functional behaviour and internal structure, the developer of each service must consider the fulfilment of its quality requirements. If the service is flexible, the output quality depends both on input quality and available resources (e.g., amounts of CPU execution time and memory). From the software engineering point of view, modelling of quality-aware requirements and architectures require modelling support for the description of quality concepts, support for the analysis of quality properties (e.g. model checking and consistencies of quality constraints, assembly of quality), tool support for the transition from quality requirements to quality-aware architectures, and from quality-aware architecture to service run-time infrastructures. Quality management in run-time service infrastructures must give support for handling quality concepts dynamically. QoS-aware modeling frameworks and QoS-aware runtime management infrastructures require a common evolution to get their integration

Pixel Features for Self-organizing Map Based Detection of Foreground Objects in Dynamic Environments

Among current foreground detection algorithms for video sequences, methods based on self-organizing maps are obtaining a greater relevance. In this work we propose a probabilistic self-organising map based model, which uses a uniform distribution to represent the foreground. A suitable set of characteristic pixel features is chosen to train the probabilistic model. Our approach has been compared to some competing methods on a test set of benchmark videos, with favorable results.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

La seguridad industrial y su relación con el desempeño laboral de los colaboradores en los talleres especializados de la empresa Sima-Callao S.A. en la Provincia Constitucional del Callao, año 2016

La investigación realizada contiene información sobre la Seguridad Industrial y su relación con el Desempeño Laboral de los colaboradores en los talleres especializados de la empresa SIMA-CALLAO S.A., en la Provincia Constitucional del Callao, año 2016. La investigación se fundamentó en el deseo de conocer con criterio científico, la situación real y actual de la organización, para lo cual se ha utilizado base de datos del SPSS V.22, luego de haber elaborado un cuestionario de 21 preguntas en escala de Likert, con la finalidad de obtener las respuestas de los encuestados lo cual nos permitirá contrastar nuestras hipótesis, posteriormente se realizó las encuestas a nuestra población de 197 colaboradores del área de talleres especializados, los mismos que conforman nuestra muestra, según el tipo de muestreo no probabilístico aleatorio simple, dichos datos han sido analizados mediante procesos estadísticos, de los cuales se ha obtenido como resultado y concluido que: La investigación ratificó la hipótesis al comprobar que la Seguridad Industrial tiene una correlación significativa con el Desempeño Laboral de los colaboradores en los talleres especializados de la empresa SIMA-CALLAO S.A., en la Provincia Constitucional del Callao, año 2016

Equilibrium control of nonlinear verticum-type systems, applied to integrated pest control

Linear verticum-type control and observation systems have been introduced for modelling certain industrial systems, consisting of subsystems, vertically connected by certain state variables. Recently the concept of verticum-type observation systems and the corresponding observability condition have been extended by the authors to the nonlinear case. In the present paper the general concept of a nonlinear verticum-type control system is introduced, and a sufficient condition for local controllability to equilibrium is obtained. In addition to a usual linearization, the basic idea is a decomposition of the control of the whole system into the control of the subsystems. Starting from the integrated pest control model of Rafikov and Limeira (2012) and Rafikov et al. (2012), a nonlinear verticum-type model has been set up an equilibrium control is obtained. Furthermore, a corresponding bioeconomical problem is solved minimizing the total cost of integrated pest control (combining chemical control with a biological one)

Micromorfología y anatomía foliar de Myrceugenia rufa (Myrtaceae). Un arbusto costero endémico de la zona centro-norte de Chile

Species of fleshy-fruited Myrtaceae are generally associated with humid environments and their vegetative anatomy is mainly mesophytic. Myrceugenia rufa is an endemic and rare species from arid zones of the coast of central Chile and there are no anatomical studies regarding its leaf anatomy and environmental adaptations. Here we describe the leaf micromorphology and anatomy of the species using standard protocols for light and scanning electron microscopy. The leaf anatomy of M. rufa matches that of other Myrtaceae, such as presence of druses, schizogenous secretory ducts and internal phloem. Leaves of M. rufa exhibit a double epidermis, thick cuticle, abundant unicellular hairs, large substomatal chambers covered by trichomes and a dense palisade parenchyma. Leaf characters of M. rufa confirm an anatomical adaptation to xerophytic environments.Las especies con frutos carnosos de Myrtaceae están generalmente asociadas a ambientes húmedos y su anatomía vegetativa es principalmente mesofítica. Myrceugenia rufa es una especie rara y endémica de lugares secos de la costa de Chile central y no hay estudios anatómicos de sus hojas en términos de adaptaciones ambientales. En este artículo describimos la micromorfología y anatomía foliar de la especie usando protocolos estándar para microscopia óptica y electrónica de barrido. La anatomía foliar de M. rufa es similar a otras especies de Myrtaceae, en lo que respecta a presencia de drusas, canales secretores esquizógenos y floema interno. Las hojas de M. rufa tienen una epidermis doble, cutícula gruesa, pelos unicelulares abundantes, cavidades subestomáticas amplias y cubiertas por tricomas, y un denso parénquima en empalizada. Los caracteres foliares de la especie confirman una afinidad morfoanatómica a ambientes xerofíticos
