Different trajectories of exosomatic energy metabolism for Brazil, Chile and Venezuela: using the MSIASM approach

Economic development goes hand in hand with an increase in the consumption of natural resources. Some analysts use material flows to describe such relationship [Eurostat 2001, Weisz et al., 2006], or exergy [Ayres et al., 2003]. Instead this paper will use a characterisation of the exosomatic energy metabolism based on expected benchmark values to describe possible constraints to economic development posed by available human time and energy. The aim of the paper is to identify types of exosomatic energy metabolism of different societies to interpret its consequences for economic development. This is done with the application of the accounting methodology called Multi-Scale Integrated Analysis of Societal Metabolism (MSIASM) to the particular case of energy metabolism for the analysis of the economies of Brazil, Chile and Venezuela.Development, Energy, Social Metabolism, MSIASM, Brazil, Chile, Venezuela

Development and implantation of a Thesaurus of Manufacturing Engineering terms

Present work shows the teaching-learning experience developed in the Department of Manufacturing Engineering of the University of Malaga. This experience is based on the need to generate a specific glossary of manufacturing engineering terms to be used as a study guide by the students. Eventually, it was decided to make a Thesaurus that would be aimed at a teaching activity. Also, it would take part in the educational innovation project PIE 13-025 of the University of Malaga, within the biennium 2013/2015. The first step consisted of the design of Thesaurus pattern, taking into account the kind of information that it was necessary include in it. Afterward, this pattern would be place on the Virtual Campus and the student would have to complete the information required. Finally, the results obtained in the different applications of this activity would be analyzed and evaluated.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MUSIASEM): An Outline of Rationale and Theory

This paper presents an outline of rationale and theory of the MuSIASEM scheme (Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism). First, three points of the rationale behind our MuSIASEM scheme are discussed: (i) endosomatic and exosomatic metabolism in relation to Georgescu-Roegen’s flow-fund scheme; (2) the bioeconomic analogy of hypercycle and dissipative parts in ecosystems; (3) the dramatic reallocation of human time and land use patterns in various sectors of modern economy. Next, a flow-fund representation of the MUSIASEM scheme on three levels (the whole national level, the paid work sectors level, and the agricultural sector level) is illustrated to look at the structure of the human economy in relation to two primary factors: (i) human time - a fund; and (ii) exosomatic energy - a flow. The three levels representation uses extensive and intensive variables simultaneously. Key conceptual tools of the MuSIASEM scheme - mosaic effects and impredicative loop analysis - are explained using the three level flow-fund representation. Finally, we claim that the MuSIASEM scheme can be seen as a multi-purpose grammar useful to deal with sustainability issues.Energy, Flow-Fund Model, Multi-Scale Integrated Analysis, Mosaic Effects, Impredicative Loop, Societal and Ecosystem Metabolism, Hierarchy, Multi-Purpose

Who takes the cake Effects of ECB monetary policy across income classes

This work provides evidence on the effects of monetary policy on the income class structure via stimulating economic activity and employment in Eurozone countries over the period 2007Q32016Q1. Based on European Union Statistics on Income and Living Conditions (EU-SILC) data, we compute the share of the market income perceived by each income class (lower, lower-middle, upper-middle, and upper) for the states that originated the Economic and Monetary Union (EMU11). We analyse the impact of monetary policy impulses under a Bayesian Vector Autoregressive approach and find that a monetary easing shock involving a decrease in nominal interest rates tends to increase the income share of middle classes at the expense of a smaller income share of the upper class, while, the lower class is not significantly affected. Our findings highlight the identified effects are mostly triggered by short-term interest rates cuts as long as they tend to vanish as the monetary policy proxy is located further in the yield curve. This suggests that the egalitarian impacts of monetary policy on market income distribution are to a lesser extent driven by decisions modifying longer-term interest rates.Universidad de Málaga.

Monetary policy and middle class

The global financial crisis of 2007-2008 and the subsequent period of financial and economic instability have forced central banks to implement ultra-loose monetary policies for combating the downturn and the stagnation of inflation, which has led the question about how monetary policy might affect inequality to the foreground of economic and political debates. This paper attepts to evaluate how monetary policy implemented in the Euro area (EURO-11) has affected two aspects of income distribution, namely, the size of middle class dimension and its mobility. To this end, an econometric model is estimated based on data from 2003 to 2015 for the set of countries belonging to the Economic and Monetary Union that originated the Union (EMU1999). We apply the vector autoregressive (VAR) methodology to country-level panel data as a first approach of the short-term dynamics among the considered variables, where the impulse-response functions have been orthogonalized due to the existing serial correlation between the unobserved terms. Subsequently, this analysis is complimented with a more robust one. Since our variables are non-stationary but indeed co-integrated, the vector error correction model (VECM) allows us to consider the medium-term relationship between monetary policy and income inequality via the stimulus of the economic activity.Universidad de Málaga.

How does monetary policy affect the income class structure? Evidence from the Eurozone.

This work provides evidence on the potential effects of monetary policy on the income class structure via stimulating economic activity and employment in the Eurozone countries over the period 2007Q3-2016Q1. Based on European Union Statistics on Income and Living Conditions (EU-SILC) data, we compute the size of income classes (lower, lower-middle, upper-middle, and upper) for the stats that originated the Economic and Monetary Union (EMU-11) and analyse the impact of monetary policy impulses under a Bayesian Vector Autoregressive approach. We focus on the earnings heterogeneity and the income composition channel and find that a monetary easing shock involving a decrease short-term nominal interest rate has diverse effects on the different income classes, which seems to have led to a more equal income distribution. As theoretically argued by these monetary policy transmission mechanisms, our results confirm the GDP growth and the decrease in unemployment caused by the monetary policies implemented by the European Central Bank since the onset of the financial crisis have had a positive effect for those households located at the bottom of the income-class structure as well as for the middle class.Campus de Excelencia Internacional Andalucía Tec

Existence, uniqueness and numerical solution of a fractional PDE with integral conditions

This paper is devoted to the solution of one-dimensional Fractional Partial Differential Equation (FPDE) with nonlocal integral conditions. These FPDEs have been of considerable interest in the recent literature because fractional-order derivatives and integrals enable the description of the memory and hereditary properties of different substances. Existence and uniqueness of the solution of this FPDE are demonstrated. As for the numerical approach, a Galerkin method based on least squares is considered. The numerical examples illustrate the fast convergence of this technique and show the efficiency of the proposed method

Técnicas de encaminamiento en redes ad-hoc basadas en criterios de potencia y batería

Las redes ad hoc están formadas únicamente por terminales móviles que funcionan a partir de baterías, es decir, no hay estaciones base. El consumo de energía es, por lo tanto, un punto muy importante ala hora de diseñar la red. Paramax.imizar el tiempo de vida de una red ad hoc, el consumo de energía tiene que ser distribuido de forma equitati va entre el conjunto de nodos que la forman, y a la vez ha de rIÚnirnizarse el consumo total de energía para cada transmisión. Los algoritmosdeencarninarniento clásicos para ad hoc no tienen en cuenta la energía y por tanto no consiguen maximizar el tiempo de vida de la red. En este artículo se hace un estudio del estado del arte en métricas de encaminamiento que tengan en cuenta la batería al seleccionar las rutas y se proponen nuevas métricas al respecto. Dichas métricas se comparan mediante simulación intentando llegar a un compromiso entre parámetros como el tiempo de vida de la red y la calidad de servicio, entre otros.Peer Reviewe

The Upper Bound Theorem in forging processes: Model of Triangular Rigid Zones on parts with horizontal symmetry

The analysis to determine the necessary forces with which to achieve a plastic deformation in metallic materials, in particular, in forging processes and under conditions of plain strain, has been raised over the years through a double approach; on the one hand, by analytical methods that involve a great complexity in their developments but that allow a direct understanding of the parameters that direct these processes. On the other hand, numerical methods, in which, thanks to the enormous development of computer technology, they provide solutions with a high approximation but, in most cases, do not allow to interpret independently the effect of each one of the parameters that come into play. The development of computers relegated analytical methods to the background. An alternative of great interest to apply these methods comes from the study of the Upper Bound Theorem by means of the Triangular Rigid Zones (TRZ) Model. One of the main limitations in the application of this model come from the fact that it is necessary to define a kinematically admissible velocity field and for complex geometric configurations of parts, this field becomes increasingly complicated. A new approach has delimited, from a theoretical perspective, a modular configuration based on a General Module formed by three TRZ that adapts to any geometry of flat surfaces of the part. Another limitation of the Upper Bound Method is the consideration of the plain strain represented by a flat section with double symmetry. Obviously, this imposition only allows to study a limited number of part configurations, which restricts its application in forging processes since the great majority of forged parts do not present geometrically this double symmetry. The present work releases one of these boundary conditions allowing to expand the possibilities of application of this method.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Integration of a Canine Agent in a Wireless Sensor Network for Information Gathering in Search and Rescue Missions

Search and rescue operations in the context of emergency response to human or natural disasters have the major goal of finding potential victims in the shortest possible time. Multi-agent teams, which can include specialized human respondents, robots and canine units, complement the strengths and weaknesses of each agent, like all-terrain mobility or capability to locate human beings. However, efficient coordination of heterogeneous agents requires specific means to locate the agents, and to provide them with the information they require to complete their mission. The major contribution of this work is an application of Wireless Sensor Networks (WSN) to gather information from a multi-agent team and to make it available to the rest of the agents while keeping coverage. In particular, a canine agent has been equipped with a mobile node installed on a harness, providing information about the dog’s location as well as gas levels. The configuration of the mobile node allows for flexible arrangement of the system, being able to integrate static as well as mobile nodes. The gathered information is available at an external database, so that the rest of the agents and the control center can use it in real time. The proposed scheme has been tested in realistic scenarios during search and rescue exercises
