Abstract: The present disclosure discloses a method of generating a master state that is a normal state in a repeated cycle by analyzing log data output from a programmable logic controller (PLC). In addition, a method of generating log data as graph data as data preprocessing for generating a master state is disclosed. The method of generating a master pattern and the method of training a cycle analysis model according to the present disclosure are different from the related art in that the methods are a technology of processing a machine control language (low-level language) that is difficult for humans to analyze and converting the machine control language into an analyzable language (high-level language), i.e., a machine language processing (MLP)-based technology that analyzes the executed machine language (a language that controls a machine) with a computer and can be understood by humans.

Abstract: This invention relates to a catalyst for preparing a cyclic hydrocarbon, which is a non-noble-metal supported on zirconium phosphate, and to a method of preparing a cyclic hydrocarbon, including preparing a cyclic hydrocarbon from a lignin derivative through hydrodeoxygenation and hydrogenation using the catalyst for preparing a cyclic hydrocarbon.
