Climate change, ethics and sustainability: An innovative approach
2018
Our goal in this article is the analysis of the state of affairs, regarding the phenomenon of climate change and its impact in different areas. We synthesize the various approaches available in the scientific debate on this subject, mainly the one that affirms the existence of global warming and the current approach, which denies it. Beyond the controversy, what seems to be evident is that there is a multifactorial causality in a phenomenon that affects anthropogenic factors a well. Since some environmentalisms exclude the human being in their consideration of the ecosystem, and if they do, they accommodate man in their approaches always as a variable that distorts and deteriorates the envi…
Beyond the audit expectations gap
1992
In seeking to encourage a broader, European dimension to research on auditing and audit expectations, this paper examines the recent history of auditing and its regulation in Spain within the context of international developments in the accounting profession. The more expansive role being assigned to the audit function in Spain following the implementation of the Fourth and Eighth European Company Law Directives is generally viewed by Spanish writers as a progressive step, with largely positive effects. Such views stand in some contrast to the history of auditing in Britain, where the prevalence of an ‘audit expectations gap’ suggests a rather more problematic state of affairs. In exploring…
Prosthetic design and prototype development
2020
Abstract In recent years, there has been worldwide interest in improvement of the mobility of people with lower-limb amputations. Despite significant development of new technologies over the last decade, commercial below-knee and above-knee prostheses are still energetically passive devices. However, many locomotive functions, like walking up stairs and slopes, need significant power in the knee and ankle joints. The additional power for carrying out these previously mentioned activities needs to be achieved by means of external energy sources, which should be integral prosthetic components. This chapter presents preliminary investigations and development towards an active robotic prosthesi…
Fifty Fuzzily Gone, Many More to Go: An Appreciation of Fuzziness’ Present and an Outlook on What May Come
2015
Fifty years of Fuzziness represents a good chance to look back on the rich history of the discipline and the scientists that were part of this history, and at the long and varied course of one of the few really innovative, disruptive ideas of the last century, including the development of its many applications. But instead we would like to take this interesting opportunity to discuss the present state of affairs, especially in relation to the application of Fuzziness to the cognitive domain. From such reflections a possible path is defined toward the evolution of Fuzziness, under the umbrella of computational intelligence, toward an all-encompassing experimental science of language, reasoni…
Design and optimization of bonded patch repairs of laminated composite structures
2015
International audience; The present study proposes a method for design optimization of external patched repairs. The tensile behavior of notched specimens with patched repair was studied using finite element analysis and compared with experimental results. It was found that high stress concentrations along the transverse edges of circular patches and/or at the longitudinal edges of the hole leads to early damage initiation in the parent plate. The damage initiation site and its propagation depend on the patch in-plane stiffness. The optimal patch design can be characterized by a strength ratio R*. The overall design of the patch repair can be considered using a dimensionless design paramete…
Engineering multi-agent systems: State of affairs and the road ahead
2019
International audience; The continuous integration of software-intensive systems together with the ever-increasing computing power offer a breeding ground for intelligent agents and multi-agent systems (MAS) more than ever before. Over the past two decades, a wide variety of languages, models, techniques and methodologies have been proposed to engineer agents and MAS. Despite this substantial body of knowledge and expertise, the systematic engineering of large-scale and open MAS still poses many challenges. Researchers and engineers still face fundamental questions regarding theories, architectures, languages, processes, and platforms for designing, implementing, running, maintaining, and e…
SmartLeg: An intelligent active robotic prosthesis for lower-limb amputees
2011
In recent years, there has been a worldwide interest in improvement of mobility of people with lower limb amputation. In spite of significant development of new technologies during the last decade, commercial below-knee and above-knee prostheses are still energetically passive devices. However, many locomotive functions, like walking up stairs and slopes, need significant power in knee and ankle joints. The additional power for doing previously mentioned activities needs to be achieved by means of external energy sources, which should be integral prosthetic components. This paper presents preliminary investigations towards an active robotic prosthesis that could potentially enable people wi…
Franchise fairs: A relevant signal in franchise choice in social activity
2016
Potential franchisees encounter difficulties in gaining knowledge about a franchise before embarking on their first start-up venture. For this reason, it is necessary to research which information signals help potential franchisees choose the franchise chains with which they wish to enter into business. Working within the framework of signaling theory, this study's aim is to analyze the relationship between franchise choice and brand, price and participation in franchise fairs. The dynamic signaling model deployed to achieve the study's aim draws on panel data methodology. This methodology allows us to analyze franchise chains over the period in which their parent franchises were using sign…
Improving Pairs Trading Using Neural Network Techniques and Fundamental Ratios
2020
Pairs trading is a quantitative trading strategy consisting on identifying two stocks that historically move together and, using the assumption that their prices difference has mean- reverting properties, exploit the deviation from the mean by taking long – short position in the chosen pair to profit. Throughout the years, different approaches have been developed in order to exploit this strategy. However, there is little literature who looks whether the divergences in the prices are generated by poor company results, i.e. whether the deviation from the mean are product of bad (or good) fundamentals and are justified, or if they generate a new equilibrium point for the pair. In addition, si…
Conflictual Rebordering: The Russia Policies of Finland and Estonia
2023
This article seeks to analyse the process of conflictual rebordering in the EU’s relations with Russia. The authors single out three major crises that triggered and shaped the process of toughening the border regime and the related transformations of political meaning of the EU-Russia border: the COVID-19 pandemic, the drastic deterioration of Moscow-Brussels relations in the beginning of 2021 and the war in Ukraine that started on 24 February 2022. Correspondingly, the EU’s reactions to each of these critical junctures might be described through the academic concepts of governmentality, normativity and geopolitics. Our aim is to look at the three ensuing models – governmental, normative an…
