Using SPICES for a better service consumption

In this poster we present SPICES (Semantic Platform for the Interaction and Consumption of Enriched Services), a Web based tool that automates the process of consuming a Web service by making use of the semantic annotations that describe them. SPICES supports both traditional WSDL services and RESTful ones and offers end-users the possibility of interacting with them in an easy yet personalised manner, without the need of advanced technical skills -which were traditionally required-, being the complexity that lies underneath hidden to them. SPICES is being developed within the European project SOA4All

Analysis of Secondary Adhesion Wear Mechanism on Hard Machining of Titanium Aerospace Alloy

Titanium alloys are widely used in important manufacturing sectors such as the aerospace industry, internal components of motor or biomechanical components, for the development of functional prostheses. The relationship between mechanical properties and weight and its excellent biocompatibility have positioned this material among the most demanded for specific applications. However, it is necessary to consider the low machinability as a disadvantage in the titanium alloys features. This fact is especially due to the low thermal conductivity, producing significant increases in the temperature of the contact area during the machining process. In this aspect, one of the main objectives of strategic industries is focused on the improvement of the efficiency and the increase of the service life of the elements involved in the machining of this alloy. With the aim to understand the most relevant effects in the machinability of the Ti6Al4V alloy, an analysis is required of different variables of the machining process like tool wear evolution, based on secondary adhesion mechanisms, and the relation between surface roughness of the work-pieces with the cutting parameters. In this research work, a study on the machinability of Ti6Al4V titanium alloy has been performed. For that purpose, in a horizontal turning process, the influence of cutting tool wear effects has been evaluated on the surface finish of the machined element. As a result, parametric behavior models for average roughness (Ra) have been determined as a function of the machining parameters used

Variation of the ultraviolet extinction law across the Taurus-Auriga star forming complex. A GALEX based study

The Taurus-Auriga molecular complex (TMC) is the main laboratory for the study of low mass star formation. The density and properties of interstellar dust are expected to vary across the TMC. These variations trace important processes such as dust nucleation or the magnetic field coupling with the cloud. In this article, we show how the combination of near ultraviolet (NUV) and infrared (IR) photometry can be used to derive the strength of the 2175 \AA\ bump and thus any enhancement in the abundance of small dust grains and PAHs in the dust grains size distribution. This technique is applied to the envelope of the TMC, mapped by the GALEX All Sky Survey (AIS). UV and IR photometric data have been retrieved from the GALEX-AIS and the 2MASS catalogues. NUV and K-band star counts have been used to identify the areas in the cloud envelope where the 2175 \AA\ bump is weaker than in the diffuse ISM namely, the low column density extensions of L1495, L1498 and L1524 in Taurus, L1545, L1548, L1519, L1513 in Auriga and L1482-83 in the California region. This finding agrees with previous results on dust evolution derived from Spitzer data and suggests that dust grains begin to decouple from the environmental galactic magnetic field already in the envelope.Comment: Accepted in Monthly Notices of the Royal Astronomical Societ

Dynamic Average Consensus with Anti-windup applied to Interlinking Converters in AC/DC Microgrids under Economic Dispatch and Delays

This work proposes an application of dynamic average consensus in interlinking converters of AC/DC microgrids with a distributed anti-windup for dealing with steady-state errors from communication delays. The proposed controller consists of a PI control that looks after the power-sharing between interlinking converters while achieving a global incremental cost consensus. The controller uses an observer (by dynamic average consensus) for estimating the average power of the interlinking converter cluster; this method represents an alternative formulation to conventional single-integrator consensus. An anti-windup with reset scheme is proposed to reduce steady-state errors in presence of fixed time delays. Stability analyses are also presented as well as simulations. Both show that the proposed controller successfully balances the power between interlinking converters being comparable with similar approaches in the literature

Viabilidad económica para la producción y venta de tilapia (oreochromis niloticus) en Amatepec, Estado de México

El objetivo fue formular y evaluar, desde el punto de vista privado y con financiamiento vía subsidio gubernamental, una propuesta de inversión adicional de un piscinegocio de tilapia. La investigación se realizó en una región del municipio de Amatepec, Estado de México, de mayo a octubre de 2014, en la que se consideró información proveniente de una granja productora de tilapia, especie niloticus, en producción y determinar así el efecto de nuevas inversiones y subsidio gubernamental en inversión fija. Se utilizó la metodología de formulación y evaluación de proyectos bajo certidumbre e incertidumbre, análisis de sensibilidad y de la situación con, sin y del efecto con menos sin el proyecto. Los resultados, permitieron evidenciar la existencia de viabilidad comercial, técnica y viabilidad financiera. Con una tasa de actualización de 12%, los indicadores de rentabilidad sin proyecto, fueron: TIR de 803.5% y el VAN 160,630 pesos, con el proyecto, la TIR fue 143.2% y el VAN 314,933 pesos; asimismo, el efecto de nuevas inversiones (con menos sin), generó una TIR de 75.8% y un VAN de 163,066 pesos. Con el proyecto, el piscinegocio se paga en 0.8 años y generaría una ganancia adicional acumulada de 314,933 pesos. El análisis de sensibilidad indicó que el piscinegocio no soportaría un precio de venta por debajo de 33 pesos/kg, ni un nivel de venta menor a 2.4 t/año. Se concluye que bajo los tres escenarios, el piscinegocio es rentable y se sugiere su ejecución. Hubo evidencia que argumenta que el piscinegocio debería salir de su cauce natural y aprovechar las nuevas inversiones

Distributed Control Strategies for Microgrids: An Overview

There is an increasing interest and research effort focused on the analysis, design and implementation of distributed control systems for AC, DC and hybrid AC/DC microgrids. It is claimed that distributed controllers have several advantages over centralised control schemes, e.g., improved reliability, flexibility, controllability, black start operation, robustness to failure in the communication links, etc. In this work, an overview of the state-of-the-art of distributed cooperative control systems for isolated microgrids is presented. Protocols for cooperative control such as linear consensus, heterogeneous consensus and finite-time consensus are discussed and reviewed in this paper. Distributed cooperative algorithms for primary and secondary control systems, including (among others issues) virtual impedance, synthetic inertia, droop-free control, stability analysis, imbalance sharing, total harmonic distortion regulation, are also reviewed and discussed in this survey. Tertiary control systems, e.g., for economic dispatch of electric energy, based on cooperative control approaches, are also addressed in this work. This review also highlights existing issues, research challenges and future trends in distributed cooperative control of microgrids and their future applications

Estimation of Energy Consumption in Street Lighting using Mobile Devices

The growing energy consumption is not sustainable in the long run. Taking into account that street lighting is one of the highest energy consumers in cities, this paper aims to develop a methodology to estimate the energy consumption of these installations with as few input variables as possible. In addition, the paper presents a mobile application developed to help lighting managers not only on the energy consumption evaluation, but suggesting the possible improvements on current systems which can save energy in case that they are implemented
