Evolving fuzzy systems are data-driven fuzzy (rule-based) systems supporting an incremental model adaptation in dynamically changing environments; typically, such models are learned on a continuous stream of data in an online manner. This paper advocates the use of visualization techniques in order to help a user gain insight into the process of model evolution. More specifically, rule chains a...

Background: The effects of kinesiophobia on pain perception in osteoarthritis patients have remained elusive. intension this study is to assess psychometric aspect pain, functional activity, and kinesophobia with chronic osteoarthritic knee pain. Methods: was time bound observational cross-section study, including 50 patients. Kinesiophobia assessed using Tampa scale (TSK-11), while physical fu...

Linear models are ususally preferable due to their simplicity. However, nonlinear models often emerge in practice. A popular approach for dealing with nonlinearities is using a piecewise-linear approximation. In such context, inspired from both Fuzzy Inference Systems (FISs) of TSK type and Self-Organizing Maps (SOMs), this work introduces enhancements based on Interval Numbers and, ultimately,...

This paper addresses the stable fuzzy controller design problem of nonlinear systems. The methodology is based on a fuzzy logic approach and the genetic algorithm (GA). I n order to analyze the system stability, the TSK fuzzy plant model is employed to describe the dynamics of the nonlinear plant. A fuzzy controller is then developed to close the feedback loop. The stability conditions are deri...

Psychological factors may be a hindrance for returning to sport after an anterior cruciate ligament (ACL) reconstruction. The ACL-Return to Sport after Injury scale (ACL-RSI) measures athletes' emotions, confidence in performance, and risk appraisal in relation to return to sport. The aim of this study was to translate the ACL-RSI scale from English to Swedish and to examine some of the measure...

Sports Research and Innovation Institute, Lithuanian Sports University, Sporto St. 6, LT-44221 Kaunas, Lithuania The effect of single acute cold water exposure on the cognitive function (short-term, working memory and attention) was examined in 25 male subjects who were exposed to 14 °C cold water (air temperature ~22 °C, rh ~45%) in the semi-recumbent posture (up to the shoulders) until the re...

BACKGROUND The contribution of kinesiophobia (fear of movement) to the pain experience among older adults has been poorly evaluated. The aim of this study was to study prevalence at baseline, development over a 12-month period and cognitive-affective variables of kinesiophobia in a population-based sample of older adults with chronic pain. METHODS The study included 433 older adults (+65 year...

Bacterial and fungal pathogens in recirculating aquaculture egg incubation systems can cause elevated mortality decreased production. Peracetic acid (PAA) is a relatively low-cost, safe, effective disinfectant; however, its toxicity to early life stages of the Atlantic salmon (Salmo salar) has not been assessed. The 24-h LC50 value PAA was determined for three salmon: eyed eggs, fry (~0.17 g), ...
