Purpose: The aim of this study is to compare the speech fluency performance of non-fluent participants namely people with stuttering (PWS), people with cluttering (PWC) and people with cluttering and stuttering (PWCS) with a fluent control group using the Turkish version of Predictive Cluttering Inventory-revised (TR-PCI-r).
Methods: The study recruited non-fluent individuals (n = 60) and fluent controls (n = 60) between the ages of 6 and 55. The non-fluent group was perceptually evaluated by two speech and language pathologists (SLP). The speaking, reading and retelling samples were collected from 18 PWC, 17 PWCS, 25 PWS and 60 controls. The scores of each factor were compared. Age and gender differences were analyzed. Validity and reliability were calculated.
Results: The agreement between two SLPs was found to be at the barely acceptable level (κ = 0.378). PWC and PWCS produced parallel outcomes in the speech motor area. In every other domain and in total scores, PWC were different from PWCS, PWS, and the controls. There was a variation in the total scores obtained by the children and adolescents in the PWS and between males and females in the controls. Except for three items (namely items 8, 22, 27), TR-PCI-r met the content validity criterion. Furthermore, TR-PCI-r was found to be a reliable tool as shown by ɑ> 0.70 and ICC values of between 0.75 and 0.90.
Conclusion: The scores from TR-PCI-r indicated that, speech motor characteristics of PWC and PWCS were similar. Other features assessed by the tool seemed to distinguish PWC from PWCS, PWS and controls.

This work focuses on studying the influence of coupling agents on the degradation in the mechanical properties of Polypropylene (PP)/wood composites. Maleic anhydride polypropylene (MAPP) was used as a coupling agent between the wood flour and PP matrix. As the coupling agent plays an important role in the stability of the WPC, a 10 wt% wood flour was mixed with PP granules along with a UV stabilizer and varying percentages (1, 3, 5 wt%) of MAPP in a twin-screw extruder to obtain PWC granules.

Monitoring joystick operations in power wheelchairs (PWCs) is promising for investigating user-wheelchair interaction and providing quantitative measures to assess the user's driving performance. In this paper, an add-on measurement system, Power Wheelchair Maneuvering Logger (PWhML), is developed to provide an easy-to-implement and cost-effective solution for monitoring the user's joystick operations in PWCs. The proposed system uses two compact inertial measurement units (IMUs), which are respectively attached to the joystick and wheelchair armrest for movement sensing.

Machine learning (ML) approaches are increasingly being applied to neuroimaging data. Studies in neuroscience typically have to rely on a limited set of training data which may impair the generalizability of ML models. However, it is still unclear which kind of training sample is best suited to optimize generalization performance.
