A survey on handling computationally expensive multiobjective optimization problems with evolutionary algorithms

2017

Evolutionary algorithms are widely used for solving multiobjective optimization problems but are often criticized because of a large number of function evaluations needed. Approximations, especially function approximations, also referred to as surrogates or metamodels are commonly used in the literature to reduce the computation time. This paper presents a survey of 45 different recent algorithms proposed in the literature between 2008 and 2016 to handle computationally expensive multiobjective optimization problems. Several algorithms are discussed based on what kind of an approximation such as problem, function or fitness approximation they use. Most emphasis is given to function approxim…

Comparison of KVP and RSI for Controlling KUKA Robots Over ROS

2020

In this work, an open-source ROS interface based on KUKAVARPROXY for control of KUKA robots is compared to the commercial closed-source Robot Sensor Interface available from KUKA. This comparison looks at the difference in how these two approaches communicate with the KUKA robot controller, the response time and tracking delay one can expect with the different interfaces, and the difference in use cases for the two interfaces. The investigations showed that the KR16 with KRC2 has a 50 ms response time, and RSI has a 120 ms tracking delay, with negligible delay caused by the ROS communication stack. The results highlight that the commercial inferface is more reliable for feedback control tas…

Modeling Energy Demand Aggregators for Residential Consumers

2013

International audience; Energy demand aggregators are new actors in the energy scenario: they gather a group of energy consumers and implement a demand- response paradigm. When the energy provider needs to reduce the current energy demand on the grid, it can pay the energy demand aggregator to reduce the load by turning off some of its consumers loads or postponing their activation. Currently this operation involves only greedy energy consumers like industrial plants. In this paper we want to study the potential of aggregating a large number of small energy consumers like home users as it may happen in smart grids. In particular we want to address the feasibility of such approach by conside…

Measuring Social Responsibility: A Multicriteria Approach

2016

In this chapter we present a portfolio selection model for Socially Responsible Investment. The model, following the spirit of Socially Responsible Investment, consists of two different steps. Firstly, a social screening is applied in order to obtain the feasible set of assets accomplishing the socially responsible investment policy of the assets’ manager. In this step, an indicator is obtained for the measurement of the social responsibility degree of an asset. Assets are then ranked using this indicator from the most socially responsible to the less socially responsible. In a second step, once the feasible set is obtained, composed of those socially responsible assets verifying the screen…

Final disposal of spent nuclear fuel (SNF) from nuclear power plants (NPPs) is an ethical issue with implications within and across generations. We address this issue from the perspective of nuclear communities that host nuclear waste disposal sites. These are primarily the communities that face injustice due to the potential radiological risks. A resident survey (n = 454) was conducted in two Finnish nuclear communities, i.e. Eurajoki and Pyhajoki, that are being considered as alternative sites for a second repository for SNF. The nuclear waste management (NWM) company Posiva is already building a repository in Eurajoki, the first in Finland. These communities are in different stages of th…

Digital Volunteers in Disaster Response: Accessibility Challenges

2019

The emergence of the Digital Humanitarian Volunteer (DHV) movements when disaster strikes have drawn the attention of researchers and practitioners in the emergency management and humanitarian domain. While there are established players in this rapidly developing field, there are still unresolved challenges, including accessibility of their digital tools and platforms. The purposes of this paper are twofold. First, it describes the background, impact and future potential of the DHV movement, and discusses the importance of universal design for the digital tools and platforms used for crowdsourcing of crisis information. Second, this paper shows how lack of concern for universal design and a…

Measuring the quality of humanitarian information products: Insights from the 2015 Nepal earthquake

2018

Information plays a critical role in humanitarian assistance. It has become a product that is shared for multiple purposes such as situational awareness, decision-making, coordination, reporting, and attracting funding. In the aftermath of sudden onset disasters, humanitarians are constrained with huge workload, time pressure, and uncertainties and thus, information products are often criticized with respect to quality issues. In this paper, we aim at developing an empirically grounded framework that can measure the quality of information products through accuracy, objectivity, completeness, and consistency. We validate the framework with the help of practitioners and apply it to the inform…

Las normas ISO/IEC como mecanismos de responsabilidad proactiva en el Reglamento General de Protección de Datos

2021

El mercado de la certificación ha experimentado un auge sin precedentes tras la entrada en vigor y ulterior aplicación del RGPD. Ello obliga a poner de relieve la relevancia de estos mecanismos como elementos claves en la prevención de potenciales violaciones de la seguridad de los datos personales. En el presente trabajo examinamos cómo la naturaleza técnica de estos instrumentos ha cedido hacia su corregulación a los efectos de garantizar una adaptación efi ciente a los continuos cambios de una gran tipología de productos, servicios o sistemas. Pretende proporcionarse una panorámica holística sobre la práctica totalidad de estándares que afectan a las dimensiones de privacidad y protecció…

Regular el juego para prevenir la adicción: hoy más necesario que nunca

2016

En mayo de 2013 aparecio la quinta edicion de la clasificacion de los trastornos mentales (DSM-5) de la American Psychiatric Association (APA, 2013), en la cual se incluye el trastorno de juego dentro de la categoria de trastornos adictivos, que es algo que era demandado desde hace decadas desde los ambitos clinicos, sociales y cientificos. El juego de azar, que segun la propia APA tiene la misma consideracion que las drogas o el alcohol en cuanto a la activacion de los circuitos cerebrales de recompensa y a las consecuencias clinicas del trastorno del juego, no tiene, sin embargo, esa consideracion desde el principal ambito desde donde se debe llevar a cabo la prevencion de la adiccion, qu…

"The human use of human beings": Interdisciplinarity, transdisciplinarity and all that in biophysics and beyond.

2017

Abstract Biophysics, just by looking at its name, indicates an interdisciplinary scientific activity, although the notion of interdisciplinarity, as such, seems to be not widely or specifically discussed by biophysicists. The same seems to have happened as well in the early stages of the development of cybernetics, notably in Norbert Wiener's writings. This situation seems to contrast with what has happened in subsequent developments of cybernetics ideas, notably in general system theory and cognitive sciences. After a few general reflections on the notion of interdisciplinarity, its sophisticated variants and the path leading to the birth of cognitive science, we shall refer to Wiener's th…
