Quality Control Analysis in the Production of Decorative Resin Lamps Using the Six Sigma and Failure Mode and Effect Analysis Methods
Published on 2025-01-31 by Arinda Soraya Putri, Adhimsa Arrizal Salam, Ahmad Kholid Al Ghofari, Siti Nandiroh @MDPI
Abstract: A creative industry company producing resin-based decorative lamps is facing quality issues due to production defects. This study applied the Six Sigma and FMEA methods to identify controls, analyze causes, and propose improvements. Six Sigma reduces defects using the DMAIC approach, while FMEA assesses risks through the Risk Priority Number (RPN). The analysis showed a DPMO of 14,587.89 and a sigma level of 3.7, aligning with industry standards in Indonesia. Key defects included bubbles (57%), [...]
Our summary: Study applies Six Sigma and FMEA methods to improve quality control in resin lamp production, identifying key defects and proposing improvements aligned with industry standards in Indonesia.

A Roadmap for Quality, Performance, and Manufacturing Tolerances
Published on 2025-01-27 by Chiweta E. Abunike, Ogbonnaya I. Okoro, Sumeet S. Aphale @MDPI
Abstract: Flux-switching wound field machines (FSWFMs) offer high torque density and independence from rare-earth materials, making them promising candidates for sustainable electric vehicles and industrial applications. However, their adoption is limited by challenges such as high torque ripple, efficiency variations, and sensitivity to manufacturing tolerances. This study presents a Design for Six Sigma (DFSS) optimization framework that integrates sensitivity analysis, response surface modeling (RSM), [...]
Our summary: A DFSS optimization framework integrates sensitivity analysis, RSM, and genetic algorithms to improve FSWFM performance and efficiency, ensuring robust performance under manufacturing variations.

Automatic Extraction and Compensation of P-Bit Device Variations in Large Array Utilizing Boltzmann Machine Training
Published on 2025-01-24 by Bolin Zhang, Yu Liu, Tianqi Gao, Jialiang Yin, Zhenyu Guan, Deming Zhang, Lang Zeng @MDPI
Abstract: A Probabilistic Bit (P-Bit) device serves as the core hardware for implementing Ising computation. However, the severe intrinsic variations of stochastic P-Bit devices hinder the large-scale expansion of the P-Bit array, significantly limiting the practical usage of Ising computation. In this work, a behavioral model which attributes P-Bit variations to two parameters, α and ΔV, is proposed. Then the weight compensation method is introduced, which can mitigate &am[...]
Our summary: Behavioral model proposed for P-Bit variations. Weight compensation method introduced. Automatic variation extraction algorithm based on Boltzmann machine learning. Ising Hamiltonian constructed for precise array variation extraction.

A Numerical Modeling Study of a New Type of Hydraulic Mechanical Continuously Variable Transmission (HMCVT) with Optimized Transmission Efficiency
Published on 2025-01-06 by Zexin Ma, Zhengyu Li, Deming Sun, Yanbin Cai, Jiwei Zhang, Hongyu Liu, Qingxin Wang, He Li, Long Zhou, Wenbin Yu, Feiyang Zhao @MDPI
Abstract: Hydraulic mechanical continuously variable transmission (HMCVT) is widely used in powerful tractors due to its excellent performance. This paper aims to find universal methods for analyzing and optimizing the transmission efficiency of HMCVT. The energy efficiency improvement of HMCVT is important for the economy of powerful tractors. Firstly, by correctly analyzing the transmission efficiency of HMCVT, the transmission efficiency during the operation of HMCVT can be accurately calculated. Secon[...]
