A Cloud-Based Architecture with embedded Pragmatics Renderer for Ubiquitous and Cloud Manufacturing

The paper presents a Cloud-based architecture for Ubiquitous and Cloud Manufacturing as a multilayer communicational architecture designated as the Communicational Architecture. It is characterised as (a) rich client interfaces (Rich Internet Application) with sufficient interaction to allow user agility and competence, (b) multimodal, for multiple client device classes support and (c) communicational to allow pragmatics, where human-to-human real interaction is completely supported. The main innovative part of this architecture is sustained by a semiotic framework organised on three main logical levels: (a) device level, which allows the user `to use' pragmatics with the system, (b) application level which results for a set of tools which allows users pragmatics-based interaction and (c) application server level that implements the Pragmatics renderer,a pragmatics supporting engine that supports all pragmatics services. The Pragmatics renderer works as a communication enabler, and consists of a set of integrated collaboration technology that makes the bridge between the user/devices and the `system'. A federated or community cloud is developed using a particular cloud REST ful Application Programming Interface that supports (cloud) services registration, composition and governance (pragmatics services behaves as SaaS in the cloud).The work is supported by the Portuguese National Funding Agency for science, research and technology (FCT), (1) Grant No. UID/CEC/00319/2013, and (2) `Ph.D. Scholarship Grant' reference SFRH/BD/85672/2012.info:eu-repo/semantics/publishedVersio

Cloudlet architecture for dashboard in cloud and ubiquitous manufacturing

The aim of this paper is to present a cloudlet architecture for dashboard in Cloud and Ubiquitous Manufacturing. In practice means that, with Cloud Computing adoption, Manufacturing requires management applications where ubiquity and effectiveness are enabled. If ubiquity and resources scalability, availability and capacity can be well supported by cloud, pragmatics instruments are required to support effectiveness. The architecture here presented shows the integration of enriched existing (cloud) services, as instances of resources, with layers of new services towards direct and synchronous communication between users. These Rich Internet Application (RIA) components, here named cloudlets, integration, follow dashboards organization patterns and will be supported by emergent web3.0 interaction technologies. In fact, the paper proposes a new Presentation Layer to be used in UMS and (that may be used) in any multi-layer cloud-based web application. (C) 2013 Authors. Published by Elsevier B.

Search for electroweak production of charginos in final states with two tau leptons in pp collisions at root s=8 TeV

Results are presented from a search for the electroweak production of supersymmetric particles in pp collisions in final states with two T leptons. The data sample corresponds to an integrated luminosity between 18.1 fb(-1) and 19.6 fb(-1) depending on the final state of T lepton decays, at root s = 8 TeV, collected by the CMS experiment at the LHC. The observed event yields in the signal regions are consistent with the expected standard model backgrounds. The results are interpreted using simplified models describing the pair production and decays of charginos or T sleptons. For models describing the pair production of the lightest chargino, exclusion regions are obtained in the plane of chargino mass vs. neutralino mass under the following assumptions: the chargino decays into third-generation sleptons, which are taken to be the lightest sleptons, and the sleptons masses lie midway between those of the chargino and the neutralino. Chargino masses below 420 GeV are excluded at a 95% confidence level in the limit of a massless neutralino, and for neutralino masses up to 100 GeV, chargino masses up to 325 GeV are excluded at 95% confidence level. Constraints are also placed on the cross section for pair production of T sleptons as a function of mass, assuming a massless neutralino.Peer reviewe

Step-wise Refinement Design Example Using LOTOS

The importance of a design methodology when using Formal Description Techniques is generally agreed in the scientific community. This paper presents some design principles and concepts that characterize a step-wise refinement design approach and illustrates their application on an example of a mutual exclusion access system. The relevance of this work is to provide a reference as to how design decisions during the design trajectory can be taken and represented in LOTOS specifications, and to evaluate the suitability of such techniques for use on an industrial scale. 1. INTRODUCTION LOTOS - Language Of Temporal Ordering Specification - is one of the Formal Description Techniques (FDTs) standardized by ISO [1] aiming at support of specification of OSI services and protocols. Due to its high expressive power, LOTOS is suitable for description of systems that display concurrency, distribution and synchronization. Since LOTOS is an International Standard and has therefore gained stabilit..

Programming Atomic Multicasts in CAN

In Distributed Computer-Controlled Systems (DCCS), a special emphasis must be given to the communication infrastructure, which must provide timely and reliable communication services. CAN networks are usually suitable to support small-scale DCCS. However, they are known to present some reliability problems, which can lead to an unreliable behaviour of the supported applications

Fuzzy Modelling: a Rule Based Approach

System modelling is an important subject in engineering, both from a research point of view and from a practical perspective. Models have an important role in several intelligent systems and, as it is observed from the research developed in the last years, fuzzy logic is relevant to this topic. This is mainly due to the expressiveness of fuzzy logic that permits the treatment of some kinds of uncertainty largely present in real systems. Also, the if-then rule mechanism is easy to manipulate and, in a certain extent, domain independent. A modelling procedure must produce good models in an effective way. This is the main concern of this paper. 1. Introduction Since its introduction in 1965 by Lofti Zadeh[15], fuzzy logic has conquered a great importance in engineering. This is partly due to the growing number of researchers in the area who have produced interesting results and in the industry whose commitment has created an important market of fuzzy logic based products [10]. Fuzzy appr..

World Wide News Gatheringautomatic Management

The world-wide-web does not support referential integrity, i.e. dangling references do exist. This can be very annoying; in particular, if a user pays for some service in the form of web pages, he requires such pages to be reachable all the time. Currently, ensuring such referential integrity is the responsibility of webmasters: while a page is referenced the corresponding file never gets deleted

Temas y actores frente al Chikungunya en medios de la prensa escrita de Paraguay

El virus Chikungunya es transmitido por mosquitos Aedes aegypti y el Aedes albopictus y produce una enfermedad febril aguda con dolor articular. El primer caso autóctono se detectó en América en diciembre de 2013. En junio de 2014, el Ministerio de Salud elaboró un plan de contingencia, que incluía la Comunicación de Riesgo. El objetivo de este estudio fue describir los temas y actores relevantes en medios de prensa, evaluar los resultados de la capacitación a periodistas y analizar cómo la información proveída por la vocería pública fue replicada en los medios privados.  Se realizó el análisis de contenido de publicaciones en medios de prensa escrita de Paraguay de junio a octubre de 2014. Se calculó la frecuencia de las variables y se compararon grupos, incluyendo pruebas de significancia, con el software Epi Info 7. De 142 publicaciones analizadas, 76 (53,5%) correspondieron al sector privado y 66 (46,5%) al público. El 60% tuvo como contenido central: el anuncio de casos (18,3%; IC95%=12,3-25,7), las medidas de control vectorial (17,6% IC95%=11,7-24,9), la alerta (12% IC95%=7,1-18,5%) o el plan de contingencia (11,3% IC95%=6,6-17,7%). Un 18,4% (IC95%= 10,4-29,0) de las noticias de prensa reprodujeron la información del sector público de manera textual y 27,6% (IC95% 18,0-39,1) lo hicieron parcialmente. Los temas fueron más frecuentemente replicados por los medios fueron el “Número de casos” (razón=2,6) y las “Alertas” (razón=2,3). Menor replicabilidad tuvo la información sobre “Plan” y “Medidas de prevención ambiental”. Se concluye que proveer información a la prensa es una acción eficaz dentro de un plan de comunicación de riesgo, pero es necesario identificar temas claves

A Society of Agents in Environmental Monitoring

The evaluation of pollutant levels is a key aspect on the issue of keeping a clean environment. Conventional techniques include the utilisation of a fixed setup incorporating pollutant sensors. However, these approaches are a very long way from an accurate monitoring. Thus, to improve pollutant monitoring on a power plant chimney, the use of robotic agent societies (mobile robots) is suggested. This suggestion is adequate in pollutant monitoring when the environment is hostile and/or the region to be sampled has large dimensions. However, the implementation of a system incorporating robotic agents raises complex technological problems. Before a set of any kind of real robotic agents is implemented, an accurate evaluation must be performed. What this paper describes is a simulation of an application of small flying robotic agent societies (helicopter models) monitoring a pollutant cloud. This simulation intends to show that an "intelligent" search method works better than a systematic o..
