Enhancing Food Safety in the Cold Chain Through Internet of Things and Artificial Intelligence
Journal of Food Science, Volume 91, Issue 2, February 2026.ABSTRACT Effective cold chain management is crucial for ensuring food safety, but traditional monitoring approaches remain reactive and fragmented. Industry 4.0 technologies, such as the Internet of Things (IoT) and artificial intelligence (AI), offer transformative potential for real‐time tracking, automation, and predictive analytics.

Analysis of inadequate cervical smears using Shewhart control charts [PDF]
BMC Public Health, 2004 Inadequate cervical smears cannot be analysed, can cause distress to women, are a financial burden to the NHS and may lead to further unnecessary procedures being undertaken. Furthermore, the proportion of inadequate smears is known to vary widely amongst providers. This study investigates this variation using Shewhart's theory of variation and control

Quality and Reliability Engineering International, Volume 41, Issue 7, Page 2952-2973, November 2025.ABSTRACT The increasing risk and impact of cyber‐physical attacks on the manufacturing industry are driven by vulnerabilities in industrial control systems and digital manufacturing technologies. These attacks can be strategically engineered to modify product dimensions while evading detection by current quality control (QC) tools.

New Shewhart-EWMA and Shewhart-CUSUM Control Charts for Monitoring Process Mean [PDF]
Scientia Iranica, 2018 In this paper, we propose new Shewhart-EWMA (SEWMA) and Shewhart-CUSUM (SCUSUM) control charts using the varied L ranked set sampling (VLRSS) for monitoring the process mean, namely the SEWMA-VLRSS and SCUSUM-VLRSS charts. The run length characteristics of the proposed charts are computed using extensive Monte Carlo simulations. The proposed charts are

Novel combined Shewhart-CUmulative EWMA-SUM mean charts without- and with measurement error
Measurement + ControlThe precision of process monitoring often encounters challenges in determining the exact shift size. Therefore, combined control charts have gained considerable attention because of their excellent speed to detect simultaneously small-to-moderate and ...
