The Pre‐Classified PBRTQC Model Can Reduce the False Positive Rate of K+

iLABMED, Volume 3, Issue 3, Page 283-291, September 2025.
Establishing patient‐based real‐time quality control models through pre‐classification of dialysis patients can significantly lower the false positive rate of K+, enhancing the accuracy of real‐time monitoring for laboratory testing systems. ABSTRACT Background Patient‐based real‐time quality control (PBRTQC) has garnered increasing attention, yet ...

An Exact Formula for the Average Run Length to False Alarm of the Generalized Shiryaev-Roberts Procedure for Change-Point Detection under Exponential Observations

, 2014
We derive analytically an exact closed-form formula for the standard minimax Average Run Length (ARL) to false alarm delivered by the Generalized Shiryaev-Roberts (GSR) change-point detection procedure devised to detect a shift in the baseline mean of a ...

Intervention in Healthcare Teams to Promote Adherence to the Integration of Care for People at Risk of Pressure Injuries Between Hospitals and Communities: A Scoping Review

International Wound Journal, Volume 22, Issue 9, September 2025.
ABSTRACT Pressure injuries (PIs) remain a problem for patient safety and the sustainability of healthcare systems. Difficulties persist in their assessment, prevention and monitoring by multidisciplinary teams. International recommendations point to this problem as a priority area for resolution in terms of patient safety.

The Application of Six Sigma to Assess the Analytical Performance of Plasma Proteins and Design a Risk‐Based Statistical Quality Control Strategy: A Multicenter Study

Journal of Clinical Laboratory Analysis, Volume 39, Issue 16, August 2025.
The six sigma model can objectively assess the analytical performance of plasma proteins. Different control concentrations yield different sigma values, which are visually displayed through standardized sigma performance verification charts. The six sigma model enables the development of personalized quality control strategies for each assay.

A Spatiotemporal Scheme for Process Control Using Image Analysis of Speckle Patterns

Quality and Reliability Engineering International, Volume 41, Issue 5, Page 1773-1788, July 2025.
ABSTRACT Conventional image‐based process control schemes require distinct, detectable features (e.g., edges or textures). In the absence of such features, current methods fail or require additional preprocessing. They are also prone to false detections from random noise, dirt, or scratches on the surface.

Statistical fault detection in photovoltaic systems [PDF]

, 2017
Faults in photovoltaic (PV) systems, which can result in energy loss, system shutdown or even serious safety breaches, are often difficult to avoid. Fault detection in such systems is imperative to improve their reliability, productivity, safety and ...
