Gaussian Mixture Model Clustering-Based Knock Threshold Learning in Automotive Engines
IEEE/ASME transactions on mechatronics, 2020In this article, a Gaussian mixture model (GMM) clustering-based method is proposed to learn the optimal threshold of the knock intensity metric, which minimizes the probability of the judgment error of the knock event.

Thus far in the book, we’ve discovered how to write code for Arduino and Python (on the Raspberry Pi) for projects that use the Qwiic and STEMMA/QT modules. Recall the simple wiring mechanism to connect those modules to your host board.

On knock-for-knock clauses and their optimal regulation
2023This article addresses two topics in relation to knock for knock contracts. The first topic is the nature and purpose of knock for knock clauses, and why we observe them in some sectors of the economy and not in others. Why, for instance, do we observe knock for knock contracts mainly in the offshore rather than in the onshore oil and gas sector?
