In this study, we introduce and study a concept of distributed fuzzymodeling. Fuzzy modeling encountered so far is predominantly of a centralizednature by being focused on the use of a single data set. In contrast to this style ofmodeling, the proposed paradigm of distributed and collaborative modeling isconcerned with distributed models which are constructed in a highly collaborativefashion. I...

The supply chains in the Electronics industry have gone through some major changes over the last decades. Today’s Electronics landscape is highly competitive, with short product lifecycles, and unpredictable demands. Many specialized players have appeared in the industry. There is a growing need for collaboration between the different parties in this industry, which can be supported by software...

In this article we introduce the main research lines concerning CSCW and groupware, which are forming the core foundation of Collaborative Working Environments (CWE). Furthermore, we introduce the problematic aspects in CWE and the features and recommendations for the integration of CWE in organizations. Through this issue readers will learn new paradigms for the building of CWE as well as dire...

Random graph theory has become a major modeling tool to study complex systems. We apply random graph theory to analyze bipartite consumer-product graphs that represent sales transaction data to understand purchase behavior in e-commerce settings. Using two real-world e-commerce datasets we found that such graphs demonstrate topological features that deviate from theoretical predictions based on...

The key focus of this paper is to introduce an approach to collaborative concept design which makes use of critical thinking styles and methods. It consists of four stages aimed to generate concept ideas, in response to identified needs, to explore them, to develop a set of solutions, and to finally choose a solution through critical examination of the solution set. Experimental findings and re...

The whole enterprise of spin compositions can be recast as simple enumerative combinatoric problems. We show here that enumerative combinatorics (EC)\citep{book:Stanley-2011} is a natural setting for spin composition, and easily leads to very general analytic formulae -- many of which hitherto not present in the literature. Based on it, we propose three general methods for computing spin multip...

The “D” matrices for all states of the two fundamental representations and octet are shown in the generalized Euler angle parameterization. The raising and lowering operators are given in terms of linear combinations of the left invariant vector fields of the group manifold in this parameterization. Using these differential operators the highest weight state of an arbitrary irreducible represen...
