In this paper, we investigate alternative distributed clustering techniques for wireless sensor node tracking in an industrial environment. The research builds on extant work on wireless sensor node clustering by reporting on: (1) the development of a novel distributed management approach for tracking mobile nodes in an industrial wireless sensor network; and (2) an objective comparison of alte...

In industrial continuous cooking systems, yields are seldom measured online. In this study, profiles for lignin, carbohydrates and total yield are constructed using physical model. The yield profiles are utilized for two kinds of digesters: conventional and Downflow Lo-Solids cooking processes. The total yield is also predicted using fuzzy clustering model.

The presence of particle-associated polycyclic aromatic hydrocarbons (PAHs) was investigated in mixed residential/light industrial, industrial and commercial zones in summer 2000 and winter 2001 in Tangshan, China. Thirteen PAHs were measured with the total average concentrations (ng/m) of PAHs ranged from 26.5 to 313.6 in summer and from 142.4 to 672.4 in winter. The average concentrations of ...

This paper describes Armil, a meta-search engine that groups the web snippets returned by auxiliary search engines into disjoint labeled clusters. The cluster labels generated by Armil provide the user with a compact guide to assessing the relevance of each cluster to his/her information need. Striking the right balance between running time and cluster well-formedness was a key point in the des...

BACKGROUND Given the serious threats posed to terrestrial ecosystems by industrial contamination, environmental monitoring is a standard procedure used for assessing the current status of an environment or trends in environmental parameters. Measurement of metal concentrations at different trophic levels followed by their statistical analysis using exploratory multivariate methods can provide m...

Compared with the conventional industrial product–service system, smart service ecosystem (SISE) mentioned in this study contains more activity according to characteristics of context, participation various stakeholders and interconnected technologies. This proposes a detailed modularization design framework for SISE, which can be referenced contexts. Firstly, context-based identification bluep...
