Synchronous R-NSGA-II: An Extended Preference-Based Evolutionary Algorithm for Multi-Objective Optimization

2015

Classical evolutionary multi-objective optimization algorithms aim at finding an approx- imation of the entire set of Pareto optimal solutions. By considering the preferences of a decision maker within evolutionary multi-objective optimization algorithms, it is possible to focus the search only on those parts of the Pareto front that satisfy his/her preferences. In this paper, an extended preference-based evolutionary algorithm has been proposed for solving multi-objective optimiza- tion problems. Here, concepts from an interactive synchronous NIMBUS method are borrowed and combined with the R-NSGA-II algorithm. The proposed synchronous R-NSGA-II algorithm uses preference information provid…

Potku – New analysis software for heavy ion elastic recoil detection analysis

2014

Time-of-flight elastic recoil detection (ToF-ERD) analysis software has been developed. The software combines a Python-language graphical front-end with a C code computing back-end in a user-friendly way. The software uses a list of coincident time-of- flight–energy (ToF–E) events as an input. The ToF calibration can be determined with a simple graphical procedure. The graphical interface allows the user to select different elements and isotopes from a ToF–E histogram and to convert the selections to individual elemental energy and depth profiles. The resulting sample composition can be presented as relative or absolute concentrations by integrating the depth profiles over user-defined rang…

On optimal relay placement for improved performance in non-coverage limited scenarios

2014

Low power nodes have been a hot topic in research, standardization, and industry communities, which is typically considered under an umbrella term called heterogeneous networking. In this paper we look at the problem of deploying optimally low power nodes in the context of relay networking, when an operator connects low power nodes (or small cells) via the wireless backhaul that uses the same spectrum and the same wireless access technology. We present an analytical model that can calculate optimal coordinates for low power nodes based on the input parameters, such as preferred number of nodes, their transmission power, parameters of the environment etc. The analytical calculations are comp…

Essence : Reference Architecture for Software Engineering - Representing Essence in Archimate Notation

2018

Essence is a standard for working with methods in software engineering. As such, it can be seen as the reference architecture for software engineering. The Essence consists of the Kernel, and a notation called the Language. This representation is not widely known and likely hinders the adoption of the Essence. This paper represents the work-in-progress of representing the Essence using ArchiMate, the de facto notation for enterprise architecture. Our purpose is to help organisations to adopt Essence by representing it in the language already understood by different stakeholders. peerReviewed

Reconsidering passivity and activity in children’s digital play

2016

The discussion around children’s digital game culture has resulted in two contradictory images of children: the passive, antisocial children uncritically and mechanically consuming digital game content and the active, social children creatively using and interacting with digital game content. Our aim is to examine how these seemingly contradictory ideas of “active” and “passive” children could be considered. By means of empirical examples of children playing digital dress-up and makeover games, we will point out that for the successful use of these concepts, they need to be thoroughly contextualized. By discussing the context and referent of activity and passivity, it is possible to overcom…

Efectos mutacionales, evolución y adaptación en bacteriófagos de RNA y DNA de cadena sencilla

2012

Las dificultades que plantean los virus para su control se deben, en gran medida, a su rápida evolución. Factores responsables de esta rápida evolución son su rápida tasa de replicación, sus elevados tamaños poblacionales y su elevada variabilidad genética. Estos dos últimos factores aumentan la efectividad de la selección natural, permitiendo a los virus escapar no sólo a las defensas del hospedador, sino también a los fármacos antivirales o de las vacunas. La mutación es la fuente última de variación genética. Por ello, la tasa de mutación es un parámetro fundamental para entender la evolución. No obstante, la relación entre tasa de mutación y adaptación no es inmediata. Por un lado, la p…

Modelling the early determinants of food preferences in the OPALINE cohort

2012

Diaporama confidentielDiaporama confidentiel; The OPALINE project aimed at understanding the determining factors of the development of food preferences and eating behaviour up to the age of 2 years by following a cohort of children with a longitudinal recording of perinatal and postnatal feeding experiences, of children’s sensitivity to food tastes and odours and of parental feeding practices. The aim was to conjointly analyse the datasets to draw an overall picture of these potential determinants of food preferences and of their relative weight over the course of the first two years.The recruitment of a cohort of children (N=314) was conducted thanks to the help of local health and childho…
