Knowledge-driven multi-agent simulation engineering for assessing the effectiveness of disaster management plans

2020

Protecting humans from disasters has been an active mission of governments and experts through the definition of disaster management plans. Defining disaster response strategies is crucial in order to reduce the number of victims and the economic impact. In order to select which response plan is best suited to a specific disaster situation, these plans must be evaluated. However, such evaluation is limited by the high cost of exercises and the specificity of existing simulation models. The approach defended in this thesis combines techniques from Semantic Web and multi-agent simulation to evaluate disaster management response plans. It is composed of four steps : (1) modeling disaster manag…

Analysis and validation in design time of distributed control systems implemented by means of rule based expert systems

2005

In this paper a new analytical method for control systems validation is presented. The control system will be implemented by means of expert systems based on rule nets, which are a formalism that seeks to express an automatism in a similar way to as would make it a human being: "IF antecedents THEN consequent". But at the same time rule nets are a tool for the design, analysis and implementation of rule based systems (RBS), and consist on a mathematic-logical structure which analytically reflects the set of rules that the human expert has designed. The validation consist on the analysis of the decisive rule nets properties in design time. This properties have been studied and formalized com…

A Novel User Interface for Knowledge Base Browsing

2019

Abstract Intuitive user interfaces have been of great concern for GUI developers. The current research, who deals with their designing, faces the term intuitive constantly. The main question is how can the Interface be intuitive? For the moment, the researchers try to provide a very intuitive generic user interface that can be used in a variety of applications. In this paper we provide a solution that can model any applied ontology into a honeycomb menu. The hexagonal shape of the honeycomb has attracted the attention of humans for centuries. As a relevant consequence, the final user can browse any knowledge base very easily with the aid of this interface. Another useful feature is that pro…

Timbrel vaults in Sicily: analysis of a little-known construction technique

2016

La ricerca di alternative al legno per la realizzazione di orizzontamenti ha condotto ad approfondimenti e sperimentazioni sulle strutture voltate, con risultati di grande originalità in grado di coniugare economia e leggerezza senza perdere in sicurezza; vengono qui analizzate le volte siciliane costituite da più fogli di mattoni sottili uniti con gesso (volte realine secondo la definizione locale). Già ampiamente documentata nella Spagna tardo-medievale, la tecnica venne introdotta saltuariamente in Sicilia a partire dalla fine del XV secolo, ed assunse un ruolo importante dalla metà del XVIII. Attraverso l’analisi diretta e delle documentazioni relative ai maggiori cantieri e dai prezzia…

Feature Ranking of Large, Robust, and Weighted Clustering Result

2017

A clustering result needs to be interpreted and evaluated for knowledge discovery. When clustered data represents a sample from a population with known sample-to-population alignment weights, both the clustering and the evaluation techniques need to take this into account. The purpose of this article is to advance the automatic knowledge discovery from a robust clustering result on the population level. For this purpose, we derive a novel ranking method by generalizing the computation of the Kruskal-Wallis H test statistic from sample to population level with two different approaches. Application of these enlargements to both the input variables used in clustering and to metadata provides a…

Large Scale Knowledge Matching with Balanced Efficiency-Effectiveness Using LSH Forest

2017

Evolving Knowledge Ecosystems were proposed to approach the Big Data challenge, following the hypothesis that knowledge evolves in a way similar to biological systems. Therefore, the inner working of the knowledge ecosystem can be spotted from natural evolution. An evolving knowledge ecosystem consists of Knowledge Organisms, which form a representation of the knowledge, and the environment in which they reside. The environment consists of contexts, which are composed of so-called knowledge tokens. These tokens are ontological fragments extracted from information tokens, in turn, which originate from the streams of information flowing into the ecosystem. In this article we investigate the u…

Recruitment, knowledge integration and modes of innovation

2015

Abstract This paper investigates how the strength and intrinsic characteristics of firms’ knowledge bases and processing routines have evolved with the past inflow of employees. The empirical analysis is based on linked public register and innovation survey data for Norway. It finds that recruitment from universities, research institutes and higher education institutions has increased the capacity of firms to generate technical inventions. Yet, the organizational knowledge bases and processing routines on which commercial innovation output depends have been strengthened only by the recruitment that has occurred from related industries. Implications for research, management and policy are dr…

CAN RETURN MIGRATION REVITALISE LATVIA’S REGIONS? FACILITATORS AND BARRIERS TO HUMAN CAPITAL GAINS

2021

Migration researchers from East-Central Europe most often focus on the impact of ‘brain drain’ which is characterised by the loss of human capital from emigration. In this paper focus is placed on the assumption that migrants living abroad gain valuable experiences and education opportunities, that lead to personal growth, facilitate entrepreneurship and psychological resilience, amongst other important skills. This experience may be used for the revitalisation of the less-developed regions the migrants return to. To explore what facilitates or inhibits the fulfil potential of ‘brain circulation’ or gain, we use data from two large-scale surveys of return migrants in Latvia, in-depth interv…
