A new paradigm: cloud agile manufacturing

Cloud Agile Manufacturing is a new paradigm proposed in this article. The main objective of Cloud Agile Manufacturing is to offer industrial production systems as a service. Thus users can access any functionality available in the cloud of manufacturing (process design, production, management, business integration, factories virtualization, etc.) without knowledge — or at least without having to be experts — in managing the required resources. The proposal takes advantage of many of the benefits that can offer technologies and models like: Business Process Management (BPM), Cloud Computing, Service Oriented Architectures (SOA) and Ontologies. To develop the proposal has been taken as a starting point the Semantic Industrial Machinery as a Service (SIMaaS) proposed in previous work. This proposal facilitates the effective integration of industrial machinery in a computing environment, offering it as a network service. The work also includes an analysis of the benefits and disadvantages of the proposal.

Cloud agile manufacturing

This paper proposes a new manufacturing paradigm, we call Cloud Agile Manufacturing, and whose principal objective is to offer industrial production systems as a service. Thus users can access any functionality available in the cloud of manufacturing (process design, production, management, business integration, factories virtualization, etc.) without knowledge — or at least without having to be experts — in managing the required resources. The proposal takes advantage of many of the benefits that can offer technologies and models like: Business Process Management (BPM), Cloud Computing, Service Oriented Architectures (SOA) and Ontologies.

Empirical study on the maintainability of Web applications: Model-driven Engineering vs Code-centric

Model-driven Engineering (MDE) approaches are often acknowledged to improve the maintainability of the resulting applications. However, there is a scarcity of empirical evidence that backs their claimed benefits and limitations with respect to code-centric approaches. The purpose of this paper is to compare the performance and satisfaction of junior software maintainers while executing maintainability tasks on Web applications with two different development approaches, one being OOH4RIA, a model-driven approach, and the other being a code-centric approach based on Visual Studio .NET and the Agile Unified Process. We have conducted a quasi-experiment with 27 graduated students from the University of Alicante. They were randomly divided into two groups, and each group was assigned to a different Web application on which they performed a set of maintainability tasks. The results show that maintaining Web applications with OOH4RIA clearly improves the performance of subjects. It also tips the satisfaction balance in favor of OOH4RIA, although not significantly. Model-driven development methods seem to improve both the developers’ objective performance and subjective opinions on ease of use of the method. This notwithstanding, further experimentation is needed to be able to generalize the results to different populations, methods, languages and tools, different domains and different application sizes.

Características cineantropométricas en jugadores de baloncesto adolescentes

Introducción: El baloncesto presenta una gran heterogeneidad antropométrica entre jugadores en relación a la posición de juego. El base suele ser el más bajo del equipo pero también el más rápido. El escolta suele ser similar al base, más bajo, rápido y ágil que el resto. El alero es de una altura intermedia entre los jugadores interiores y exteriores, combina la altura con la velocidad, y el pívot tiene un rol más físico, es el más alto y con mayor masa muscular. El objetivo del estudio es describir el perfil cineantropométrico del equipo cadete masculino del Valencia Basket Club. Material y Métodos: Se han evaluado 20 jugadores de baloncesto cadete masculino (15,35±0,59años). Un antropometrista nivel I tomó las medidas según la metodología de la Society for the Advancement of Kinanthropometry (ISAK). Se calculó la composición corporal según el consenso de cineantropometría del Grupo Español de Cineantropometría (GREC), el somatotipo según Heath-Carter, e índices adiposo-musculares. Resultados: Se observaron diferencias en los valores de peso, talla, pliegues cutáneos y composición corporal, de las variables estudiadas de la muestra total y por posición de juego, siendo los valores menores los de la posición base y mayores en los pívots. Se estableció una tendencia creciente de estos parámetros en el siguiente orden: base, escolta, alero y pívot. Conclusiones: El somatotipo global del jugador de baloncesto cadete del Valencia Basket Club es ectomorfo balanceado. Conocer el perfil cineantropométrico puede beneficiar la elaboración de planes de entrenamiento y nutrición, así como reflejar la evolución y dirigirla hacia las características ligadas al rendimiento óptimo.
