A recommendation system for an extended process of information retrieval in distributed information systems is proposed. This system is both a model of dynamic cognitive categorization processes and powerful real application useful for knowledge management. It utilizes an extension of fuzzy sets named evidence sets as the mathematical mechanisms to implement the categorization processes. It is ...

Water environments appear to be the habitats of Legionella species. Legionellosis is considered as a preventable illness because bacterial reservoirs can be controlled and removed. Roof-harvested rainwater has attracted significant attention not only as a groundwater recharge but also as a potential alternative source of nonpotable water. We successfully developed ceramic microbeads coated with...

Soil-structure interaction (SSI) could affect the seismic response of structures. Since liquid storage tanks are vital structures and must continue their operation under severe earthquakes, their seismic behavior should be studied. Accordingly, the seismic response of two types of steel liquid storage tanks (namely, broad and slender, with aspect ratios of height to radius equal to 0.6 and 1.85...

An open-ended carbon nanotube or a tubule is a part of some regular hexagonal tessellation of a cylinder. A tubule T is said to be k-resonant if for every k (or fewer) pairwise disjoint hexagons, the subgraph obtained from T by deleting all the vertices of these hexagons must have a Kekule structure (perfect matching) or must be empty. The 1-resonant tubules can be constructed by an approach pr...

This paper introduces a new classification scheme called “open-ended texture classification.” The standard approach for texture classification is to use a closed n-class classifier based on the Bayesian paradigm. These perform supervised classification, whereby all the texture classes have to be predefined. We propose a new texture classification scheme, one that does not require a complete set...

Background: Manual coding of open-ended survey responses is time-consuming, expensive, and error-prone. However, this task can be recast as a multi-label text classification problem, to which natural language processing and machine learning techniques can be applied. Aim: The aim of this work is to assess the suitability of various machine learning techniques to the problem of automated coding ...

We introduce a simple open-ended model which describes the emergence of a shared vocabulary. The ordering transition towards consensus is generated only by an agreement mechanism. This interaction defines a finite and small number of states, despite each individual having the ability to invent an unlimited number of new words. The existence of a phase transition is studied, analyzing the conver...

A total of 352 open-ended attributions were obtained in two field studies with volleyball teams and in two lab experiments, all involving team competition. All attributions were classified along the three causal dimensions of locus of causality, stability, and controllability. Attributions were also classified as referring to the self, to teammates, to the team as a whole, or to other factors a...

We have built up an open-ended computerized overview which can give instant access to information because controlled languages (CLs) are of undoubted interest (for safety and economic reasons, etc.) for industry and those willing to create a CL need to be aware of what has already been done. To achieve it, we had a close look at what has been written in the field of CLs and tried to get in touc...
