Publication number: 20240143461Abstract: Systems and methods related to prediction-based resource orchestration in a service fabric are described. An example method for reducing an interruption rate associated with a customer application offered as a collection of services includes predicting one or more quiet time periods associated with each of the service replicas associated with a service fabric, where each of the one or more quiet time periods corresponds to a low value of a predicted load specifying a consumption of a metric by a respective service replica on a given node. The method further includes during the one or more quiet time periods predicted by a trained machine learning model, performing an impact-less failover for one or more of the service replicas by scheduling a move for the one or more service replicas from a first node associated with the service fabric to a second node associated with the service fabric.Type: ApplicationFiled: October 31, 2022Publication date: May 2, 2024Inventors: Neda M.

Patent number: 8877669Abstract: Provided are hydroisomerization catalysts for processing a bio-based feedstock into biodiesel fuels. These catalysts comprise a catalytic material and a matrix component. The catalytic material is made up of a molecular sieve that has a pre-loaded platinum group metal. The catalytic material and the matrix component are processed together to form the hydroisomerization catalyst. Methods of making these hydroisomerization catalysts include synthesizing a molecular sieve; purifying the molecular sieve; associating the molecular sieve with a platinum group metal in the absence of the matrix component to form the pre-loaded molecular sieve before formation of a catalyst body; mixing the pre-loaded molecular sieve with the matrix component to form a mixture; processing the mixture to form a catalyst body; and drying and calcining the catalyst body to form the hydroisomerization catalyst. These hydroisomerization catalysts can be used to process hydrodeoxygenated plant- or animal-derived feeds to yield a biofuel.Type: GrantFiled: July 29, 2011Date of Patent: November 4, 2014Assignee: BASF CorporationInventors: Michael A.
