Abstract: Systems and methods are provided for evaluating a maintenance report. A maintenance report is received for an item of modular industrial equipment. The maintenance report includes a maintenance-related code, selected from a defined library of maintenance-related codes, and a free text field describing either or both of an observation of the item of modular equipment that is inconsistent with a defined specification and an action taken to repair or maintain the item of modular industrial equipment. A plurality of features representing the semantic content of a free-text field are extracted, with at least a portion of the plurality of features being extracted via a document embedding approach. At an expert system, a new maintenance-related code is determined from the defined library of maintenance-related codes for the item of modular industrial equipment, from the plurality of features.

Abstract: A system and a method for secure operator onboarding and creating an ingest job agent for secure multitenant operations of a distributed computing cluster are provided. Embodiments automate multitenant operations for distributed computing clusters. These operations include automation of operator onboarding, creation of logically segregated distributed data stores within the distributed computing clusters for the on-boarded operator, and creation of ingest agents with security isolation for transfer of large quantities of files into the distributed computing clusters. Embodiments provide multitenant security, in which the same Hadoop cluster serves multiple operators with each operator's data and processes in effective isolation. In this manner, multitenant security keeps each user's data storage and operations on the Hadoop cluster separated from other operators.

Abstract: Systems, methods, and computer program products useful in controlling the fragmentation of ions. Control of fragmentation is achieved by varying the collision energy imparted to precursor ions.
