A Simple Object that Spans the Whole Consensus Hierarchy [article]

Achour Mostéfaoui, Matthieu Perrin, Michel Raynal
2018 arXiv   pre-print
This paper presents a simple generalization of the basic atomic read/write register object, whose genericity parameter spans the whole set of integers and is such that its k-parameterized instance has  ...  Its interest lies in its simplicity and its genericity dimension which provides a global view capturing the whole consensus hierarchy.  ...  Acknowledgments This work has been partially supported by the French ANR project DESCARTES devoted to layered and modular structures in distributed computing.  ...

Defining and predicting sustainability

Robert Costanza, Bernard C. Patten
1995 Ecological Economics  
We argue that because we can only assess sustainability after the fact, it is a prediction problem more than a definition problem.  ...  We also propose that in order for evolutionary adaptation to occur, there must be an ordered, hierarchical relationship between the expected (finite) life spans of systems and their space and time scales  ...  Acknowledgements We wish to thank Buzz Holling, Simon Levin, and one anonymous reviewer for their helpful suggestions on a earlier version of this manuscript.  ...

Computation of the Optimal Probability of becoming a Cluster Head in Hierarchical Clustered WSNs

Mostafa Saadi, M. Lahcen Hasnaoui, Abderrahim Beni Hssane, Mohamed Laghdir
2013 International Journal of Computer Applications  
The clustering algorithm is a key technique used to increase the scalability and life span of the network in general.  ...  Wireless Sensor Networks (WSNs) consist of a large number of energy-limited sensor nodes that are densely deployed in a large geographical region.  ...  Moreover, the interaction occurs through a very simple mechanism that does not require complicated modulation, MAC, or routing strategies.  ...

Ontological descriptions of receiver states for sharing knowledge in learning service design

Keiichi MURAMATSU, Koji KIMITA, Takatoshi ISHII, Yutaro NEMOTO, Eiichirou TANAKA, Keiichi WATANUKI, Tatsunori MATSUI, Yoshiki SHIMOMURA
2017 Journal of Advanced Mechanical Design, Systems, and Manufacturing  
That is, a receiver creates value independent of the value generated by a provider. Indeed, value co-creation takes place in a joint sphere where providers and customers interact with each other.  ...  Then, we demonstrated instances of a consensus building, which is extracted from conversations during counseling by a teacher (mentor) and a learner.  ...  "collective creativity as it is applied across the whole span of a design process."  ...

Towards An Executable Sociotechnical Model For Product Development And Engineering Systems

Axel Hahn, Juergen Geuter
2014 ECMS 2014 Proceedings edited by: Flaminio Squazzoni, Fabio Baronio, Claudia Archetti, Marco Castellani  
In this paper we outline the specific challenges and requirements for creating a complete model of social product development systems.  ...  Individual skills and properties of the human beings involved have made analyzing product development systems difficult.  ...  ENGINEERING SYSTEMS Engineering or designing a product is, on a very abstract level, the exploration of the design space spanned by the given requirements or objectives.  ...

Ultrametric Component Analysis with Application to Analysis of Text and of Emotion [article]

Fionn Murtagh
2013 arXiv   pre-print
This work is completed by a review of related work, on consensus hierarchies, and of a major new application, namely quantifying and interpreting the emotional content of narrative.  ...  It is assumed that the data set, to begin with, is endowed with a metric, and we include discussion of how this can be brought about if a dissimilarity, only, holds.  ...  From the Ultrametric Consensus Set to a Consensus Hierarchy We form a consensus hierarchy as follows.  ...

Aditya Parameswaran, Akash Das Sarma, Vipul Venkataraman
2016 arXiv   pre-print
We describe the approaches that we've found to be effective for open-ended crowdsourcing, drawing from our experiences in this space.  ...  selecting between the many open-ended operators appropriate for a problem.  ...  Our open-ended operator is simple-we display an image or a portion of an image, and ask workers to provide the count of the number of objects in that portion.  ...

Multi-image Segmentation: A Collaborative Approach Based on Binary Partition Trees [chapter]

Jimmy Francky Randrianasoa, Camille Kurtz, Éric Desjardin, Nicolas Passat
2015 Lecture Notes in Computer Science  
To solve the induced segmentation fusion issues, various strategies have been already investigated for allowing a consensus between several segmentation outputs.  ...  This framework is, in particular, designed to embed consensus policies inherited from the machine learning domain.  ...  , i.e., during the construction of a hierarchy that models the n images.  ...

Ecotourism is a complex phenomenon that has grown rapidly in the last three decades. The emerging field of inquiry based on this phenomenon has followed a similar trajectory of growth.  ...  We explain how key concepts from hierarchy theory are of relevance to levels of analyses of ecotourism whether conducted on individual people or destinations or on the global phenomenon as a whole.  ...  , class, family, genus, species) Exclusive hierarchy Groups of objects or processes that are ranked as lower in hierarchy are not contained in or subdivisions of groups that are ranked as higher in the  ...
