In this contribution, we describe a hardware platform for evolving a fuzzy system by using Fuzzy CoCo — a cooperative coevolutionary methodology for fuzzy system design — in order to speed up both evolution and execution. Reconfigurable hardware arises between hardware and software solutions providing a trade-off between flexibility and performance. We present an architecture that exploits the ...

We present the most applicable aspects of our research in the conceptual integration of terminologies. From past experience, we claim that the conceptualizations provided for terminological ontologies need to be philosophically and linguistically grounded. We developed ONIONS, a methodology for integrating domain terminologies by exploiting a library of generic ontologies. Our current focus is ...

In this paper we adapt Axelrod’s metanorms model to run on arbitrary interaction structures. We propose a hybrid analytical methodology combining computer simulations with a novel mathematical approach that abstracts some details of evolutionary dynamics while retaining explicit and exact representation of underlying network topology. We construct simple network statistics based on the clusteri...

Cooperative co-evolution is often used to solve difficult optimization problems by means of problem decomposition. In order to do so efficiently, one must have a good understanding of co-evolution’s dynamical behavior. To build such understanding, we have constructed a methodology for analyzing co-evolution based on dynamical systems theory. In this paper we show how it can be applied to invest...

This paper investigates a method for modelling computersupported cooperative work, to provide a common language for users and developers collaborating in design. The research is grounded in an empirical study of the inhouse development of groupware and the work practice of system developers. Through an appropriation of Christopher Alexander’s architectural pattern language, it is proposed that ...

A revelatory case study has been conducted to investigate the influence of the organizational culture on risks in IT projects. Following the Grounded Theory Methodology, we interviewed 26 experts from a large financial service provider. We selected a company from the cooperative banking sector, which makes this case unique. With Giddens’ Structuration Theory as a theoretical lens, we show how t...

The performance of women agribusiness cooperatives in Oyo State, Nigeria was assessed in this study. The study employed a multi-stage sampling technique to select 6 women cooperative groups (aggregating to 175 individuals); 36 individual women; and 4 institutions across 6 LGAs in two agricultural zones of the State. Findings show that majority (55.6%) of the respondents belong to processing org...

Cooperative learning has been found to affect different aspects of language learning by many researchers (e.g., Kagan, 1995; Kagan, 1999; Kessler, 1992; McGroarty, 1993). Likewise, mobile assisted language learning (MALL) has revealed significant impacts on the improvement of different language skills and components (e.g., Comas-Quinn et al. 2009; Divitini & Chabert, 2009; Motallebzadeh & Ganja...

Cooperative and gradual covering are two new methods for developing covering location models. In this paper, a cooperative maximal covering location–allocation model is developed (CMCLAP). In addition, both cooperative and gradual covering concepts are applied to the maximal covering location simultaneously (CGMCLP). Then, we develop an integrated form of a cooperative gradual maximal covering ...
