Cluster-based exposure variation analysis
BACKGROUND Static posture, repetitive movements and lack of physical variation are known risk factors for work-related musculoskeletal disorders, and thus needs to be properly assessed in occupational studies. The aims of this study were (i) to investigate the effectiveness of a conventional exposure variation analysis (EVA) in discriminating exposure time lines and (ii) to compare it with a ne...
متن کاملInterpolating time series based on fuzzy cluster analysis problem
This study proposes the model for interpolating time series to use them to forecast effectively for future. This model is established based on the improved fuzzy clustering analysis problem, which is implemented by the Matlab procedure. The proposed model is illustrated by a data set and tested for many other datasets, especially for 3003 series in M3-Competition data. Comparing to the exist...
متن کاملErgoVar: A Toolbox for Exposure Variation Analysis
Lack of exposure variation has been suggested to be associated with development of work related musculoskeletal disorder in “repetitive works” [1]. As a remedy, ergonomists have suggested exploiting of redundancy of human motorcontrol toincrease the variation in pattern of biomechanical loading [2,3]. Further, a similar concept has attracted attention within the sport science field where the im...
متن کاملCluster Analysis for Object-Oriented Verification of Fields: A Variation
In a recent paper, a statistical method referred to as cluster analysis was employed to identify clusters in forecast and observed fields. Further criteria were also proposed for matching the identified clusters in one field with those in the other. As such, the proposed methodology was designed to perform an automated form of what has been called object-oriented verification. Herein, a variati...
متن کاملCharacterization of population exposure to organochlorines: a cluster analysis application.
This study aimed to show the results from a cluster analysis application in the characterization of population exposure to organochlorines through variables related to time and exposure dose. Characteristics of 354 subjects in a population exposed to organochlorine pesticides residues related to time and exposure dose were subjected to cluster analysis to separate them into subgroups. We perfor...
