PolyACO+: a multi-level polygon-based ant colony optimisation classifier

2017

Ant Colony Optimisation for classification has mostly been limited to rule based approaches where artificial ants walk on datasets in order to extract rules from the trends in the data, and hybrid approaches which attempt to boost the performance of existing classifiers through guided feature reductions or parameter optimisations. A recent notable example that is distinct from the mainstream approaches is PolyACO, which is a proof of concept polygon-based classifier that resorts to ant colony optimisation as a technique to create multi-edged polygons as class separators. Despite possessing some promise, PolyACO has some significant limitations, most notably, the fact of supporting classific…

Public Administration and the Study of Political Order: Towards a Framework for Analysis

2020

The contribution of this study is two-fold: First, it outlines a conceptual framework on political order; and secondly, it offers empirical illustrations on the case of Nordic cooperation. Taken together, the article makes a plea for public administration scholarship in the study of political order. Political order consists of a relatively stable arrangement of institutions that are fairly formalized and institutionalized. A common political order, moreover, entails that relevant institutions: (i) are fairly independent of pre-existing institutions; (ii) are relatively integrated and internally cohesive; and (iii) are reasonably able to influence governance processes within other institutio…

The Complex System Theory for the Analysis of Inter-Firm Networks: A Literature Overview and Theoretic Framework

2011

In this paper we discuss the body of knowledge known as complex system theory and its relevance to the analysis of inter-firm networks. We start by addressing the development of systems thinking. Through a literature overview, we point out the main elements for the development of systemic thought from its beginning, through its application in business sciences, to the birth of Complex Systems Theory (CST). With these initial annotations we provide an introduction to the concepts of the complex systems theory. We will underscore those aspects of CST that can be useful to analyze inter-firm networks, in order to highlight the evolutionary dynamics of the networks and to clarify the logical li…

La partecipazione ad un business ecosystem: implicazioni per la nozione di successo

2020

L’obiettivo del capitolo è offrire un’introduzione alla letteratura sugli ecosistemi aziendali e discutere critica-mente la tematica del successo e della misurazione delle performance del business ecosystem e degli attori che vi partecipano. A tale scopo, il capitolo è strutturato come segue. Il paragrafo 2 focalizza l’attenzione sulla definizione di business ecosystem. I paragrafi 3, 4 e 5 spiegano, rispettivamente, perché nasce un business ecosystem, chi sono gli attori e quali sono le strutture sottese agli ecosistemi aziendali. Il paragrafo 6 discute la misurazione delle performance del business ecosystem focalizzando l’attenzione sui seguenti aspetti: (a) indicatori di performance a li…

A system for sign language sentence recognition based on common sense context

2005

The paper proposes a complete framework for sign language recognition that integrates common sense in order to deal with sentences. The proposed system is based on a cognitive architecture allows modeling and managing the knowledge of the recognition process in a simple and robust way. The final abstraction level of this architecture introduces the semantic context and the analysis of the correctness of a sentence given a sequence of recognized signs. Experimentations are presented using the Italian sign language (LIS), and shows that the system maintains the recognition rate high when set of sign grows, correcting erroneous recognized single sign using the context

Macro-regional strategies of the European Union, Russia and multilevel governance in northern Europe

2017

The European Union’s Strategy for the Baltic Sea Region (EUSBSR): improving multilevel governance in Baltic Sea cooperation?

2017

ABSTRACTMacro-regional strategies – such as the ones for the Baltic Sea, the Danube, the Ionian-Adriatic, and the Alpine regions – constitute new elements of European Union (EU) Cohesion Policy and territorial cooperation. In a nutshell, these strategies aim at building functional and transnational ‘macro-regions’ involving the EU, its member states, as well as partner countries within the EU’s system of multilevel governance (MLG). As the oldest macro-regional strategy, the EU Strategy of the Baltic Sea Region has been in operation since 2009. Drawing on the theory of MLG, this contribution assesses the effects on the political mobilization and interplay between international, intergovernm…

Reconfigurations in sustainability transitions : a systematic and critical review

2021

Two streams of literature have become especially prominent in understanding social change toward sustainability within the past decades: the research on socio-technical transitions and applications of social practice theory. The aim of this article is to contribute to efforts to create dialogue between these two approaches. We do this by focusing on the concept of reconfiguration, which has become a much-used, but poorly defined notion in the discussion on sustainability transitions. To understand what is defined as reconfiguration in systems and practices, and how the understanding of reconfiguration in regimes could benefit from insights about reconfiguration in practices, we conducted a …

The role of governance in realising the transition towards sustainable societies

2016

It is widely known that governance is central to the successful implementation of sustainable development policies and measures. Yet, there is a paucity of research which explore the links between governance and sustainability. This paper attempts to address this research need by providing an analysis of the role of governance in enabling - and to some extent - fostering a transition towards sustainable societies. A set of indicators for assessing the capacity for and willingness and commitment to transition to a more sustainable society is presented, enabling identification of direction of change. This paper presents the results of a study, in the context of which sustainability governance…

Improving MLC flash performance and endurance with extended P/E cycles

2015

The traditional usage pattern for NAND flash memory is the program/erase (P/E) cycle: the flash pages that make a flash block are all programmed in order and then the whole flash block needs to be erased before the pages can be programmed again. The erase operations are slow, wear out the medium, and require costly garbage collection procedures. Reducing their number is therefore beneficial both in terms of performance and endurance. The physical structure of flash cells limits the number of opportunities to overcome the 1 to 1 ratio between programming and erasing pages: a bit storing a logical 0 cannot be reprogrammed to a logical 1 before the end of the P/E cycle. This paper presents a t…
