Statistical Process Control

open access: yesInternational Journal of Research in Engineering and Technology, 2013
The aim of statistical process control (SPC) techniques, when applied to control-loop operating data, is to identify and track certain variation within the loop, and thus highlight situations that show abnormal behaviour, i.e. statistically significant events or abnormalities.

Process adjustment by a Bayesian approach

open access: yesCogent Engineering, 2015
In a production or measure situation, operators are required to make corrections to a process using the measurement of a sample. In both cases, it is always difficult to suggest a correction from a deviation. The correction is the result of two different

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching
