Consensus via multi-population robust mean-field games
2017
In less prescriptive environments where individuals are told ‘what to do’\ud but not ‘how to do’, synchronization can be a byproduct of strategic thinking,\ud prediction, and local interactions. We prove this in the context of multipopulation\ud robust mean-field games. The model sheds light on a multi-scale\ud phenomenon involving fast synchronization within the same population and\ud slow inter-cluster oscillation between different populations.
Tolerating malicious monitors in detecting misbehaving robots
2008
This paper considers a multi–agent system and focuses on the detection of motion misbehavior. Previous work by the authors proposed a solution, where agents act as local monitors of their neighbors and use locally sensed information as well as data received from other monitors. In this work, we consider possible failure of monitors that may send incorrect information to their neighbors due to spontaneous or even malicious malfunctioning. In this context, we propose a distributed software architecture that is able to tolerate such failures. Effectiveness of the proposed solution is shown through preliminary simulation results.
Types of Mimetics for the Design of Intelligent Technologies
2019
Mimetic design means using a source in the natural or artificial worlds as an inspiration for technological solutions. It is based around the abstraction of the relevant operating principles in a source domain. This means that one must be able to identify the correct level of analysis and extract the relevant patterns. How this should be done is based on the type of source. From a mimetic perspective, if the design goal is intelligent technology, an obvious source of inspiration is human information processing, which we have called cognitive mimetics. This article offers some conceptual clarification on the nature of cognitive mimetics by contrasting it with biomimetics in the context of in…
The impact of the volumetric swelling behavior on the water uptake of gas shale
2018
Abstract Water uptake of gas shales is commonly considered one of the most important factors responsible for fluid loss during flowback operations after hydraulic fracturing. Imbibition experiments cover a key role in this context to analyze the impact of several factors (such as mineralogical composition, fluids composition, anisotropic structure, volumetric swelling) that contribute to the water uptake in these unconventional reservoirs. The aim of this study is the quantification of the impact of the volumetric response (swelling and shrinkage) of gas shales on the water uptake during imbibition and desiccation processes. An experimental methodology to quantify the volumetric response du…
On the Influence of Affect in EEG-Based Subject Identification
2021
Biometric signals have been extensively used for user identification and authentication due to their inherent characteristics that are unique to each person. The variation exhibited between the brain signals (EEG) of different people makes such signals especially suitable for biometric user identification. However, the characteristics of these signals are also influenced by the user’s current condition, including his/her affective state. In this paper, we analyze the significance of the affect-related component of brain signals within the subject identification context. Consistent results are obtained across three different public datasets, suggesting that the dominant component of the sign…
Cognitive biases in humanitarian sensemaking and decision-making lessons from field research
2016
Time and again, humanitarian decision-makers are confronted with stress and pressure, distorted, lacking and uncertain information, and thus they are working in conditions that are known to introduce or enforce biases. Decision analysis has been designed to overcome such biases, and a network of “digital responders” organized over the Internet has set out to improve judgments by providing better information. However, without any structured support to determine objectives, goals and preferences and detached from the context of operational decision-makers, remote analysts may face the very biases they are trying to help overcome. This article sets out to identify biases that matter for humani…
The organization of the defense support system: an economic geography perspective
2017
In the context of restricted budgetary resources and the growing cost of maintenance, repair, and overhaul (MRO) activities, a major issue for modern armed forces is to sustain defense platforms. A possible method consists of realizing economies of scale through the concentration of maintenance activities, which involves the spatial reorganization of existing industrial sites dedicated to MRO. This article provides a formalized framework to discuss the optimal organization for the MRO of defense platforms in space. The public planner organizes the maintenance of defense platforms with only two possible spatial configurations. In the dispersed configuration, two industrial production units i…
Can Gender Equality Be Institutionalized?
1999
Institutional innovation can be understood as launching an institution within an intact institutional and cultural context. Such attempts of guided institutionalization pose a crucial built-in problem. The goal of institutional innovation is to create new routine-reproduced, taken-for-granted behaviour patterns. The means to reach this goal is rational, purposive action, which is the very opposite of routinized enacting. This immanent contradiction of institutional innovation is discussed on the basis of a comparative study on the introduction of gender quotas in Norwegian and German political parties. The analysis draws on more than 50 qualitative interviews with parliamentarians from bot…
The 2015 Spanish election: the times they are a’ changing
2016
ABSTRACTThe Spanish legislative election of 2015 speaks of change. This is the end of the traditional two-party system and the beginning of a new political era marked by institutional renewal. The Socialist Party and the Partido Popular have both lost significant parliamentary force, whereas two new parties (Podemos, and Ciudadanos) are now crucial to ensure stable government majorities. This new parliamentary scenario seems to better mirror the political pluralism of a changing society which has already demonstrated for change in striking events such as the 15-M Movement. However, political parties are far from showing conciliatory aspirations, possibly because a new election is suddenly a…
Committee Parliamentary Specialization Index. Explaining MPs’ specialisation in the Spanish Congreso de los Diputados
2019
Nowadays legislatures are largely based on committee systems. This enables a division of work and specialisation, in the context of highly complex politics and policy development. It seems clear that MP specialisation in the field of the committee they serve on is an important political asset, both for MPs and their parliamentary party group. This paper presents the Committee Parliamentary Specialization Index. This index measures the degree an MP is specialised in the jurisdiction of the committee they serve on. In the second part of the paper, the index is applied to the Spanish Congreso de los Diputados, an interesting case for testing this multi-faceted index, to find institutional, pol…
