Abstract: An automated tuning service is used to automatically tune, or modify, the operational parameters of a large-scale cloud infrastructure. The tuning service performs automated and fully data/model-driven configuration based from learning various real-time performance of the cloud infrastructure. Such performance is identified through monitoring various telemetric data of the cloud infrastructure. The tuning service leverages a mix of domain knowledge and principled data-science to capture the essence of our cluster dynamic behavior in a collection of descriptive machine learning (ML) models. The ML models power automated optimization procedures for parameter tuning, and inform administrators in most tactical and strategical engineering/capacity decisions (such as hardware and datacenter design, software investments, etc.).

Abstract: The present disclosure relates to a method for making a ceramic mini-tube configured for use in a fluid modification system. The method involves using an electrospinning system to receive a quantity of precursor solution. The electrospinning system creates an electric field which causes the precursor solution, when emitted, to be stretched into a fiber jet. The fiber jet is deposited on a collector resulting in a fiber mat. The fiber mat is removed from the collector, wherein the fiber mat is formed into a shape. The fiber mat is further processed so that the fiber mat retains a desired shape. A heat treatment operation is then performed to convert the fiber mat into a ceramic structure having the desired shape.

Abstract: In a computing resource environment including at least one resource capable of being allocated to at least one of a plurality of tasks, techniques are disclosed for applying a taint to a resource in a computing resource environment, the taint being configured to prevent the resource from being claimed for a resource request without a toleration to that taint. Variations include receiving, at a resource scheduler in the resource environment, a request to allocate the resource to perform a particular task and determining whether the resource is subject to a taint. If the resource is subject to a taint, analyzing the request to determine if it includes a toleration for the taint. If the request includes a toleration for the taint, allocating the resource to the task. If the request does not include a toleration for the taint, not allocating the resource due to the taint.
