Abstract: A method for fabricating an interface coating on a substrate, comprising (i) providing a substrate; (ii) depositing on the substrate at least one layer of boron nitride; and (iii) depositing on the boron nitride layer a Si3N4-BN multilayer coating to form a coated substrate, the Si3N4-BN multilayer coating comprises a pattern of alternating layers having at least one boron nitride layer and at least one silicon nitride layer according to the following steps: (iiia) depositing at a first deposition temperature a layer of silicon nitride at a first thickness; (iiib) depositing at a second deposition temperature a layer of boron nitride at a second thickness; and repeating steps (iiia) and (iiib) until forming the Si3N4-BN multilayer coating.

Abstract: A method of forming z-channels in a fibrous ceramic preform includes mounting the preform in a tooling assembly, the tooling assembly comprising a first fixture and a second fixture, heating the preform mounted in the tooling assembly to a temperature above a glass transition temperature of a polymer binder within the preform to induce a softened state of the polymer binder, inserting a plurality of needles sequentially through respective first holes in the first fixture, the preform, and respective corresponding second holes in the second fixture, and removing the plurality of needles leaving behind a corresponding plurality of z-channels in the preform.

Abstract: A method and system for facilitating utilization of reward points is provided. A set of users is identified from multiple users such that the reward points associated with payment modes of the set of users are set to expire after a first time period. Further, a transaction history of the set of users is analyzed to detect at least one transaction that is associated with a sustainable initiative for each of the set of users. Based on the analysis, users are selected from the set of users such that the transaction history of each of the selected users is associated with at least one of the sustainable initiatives. Further, the selected users are notified to donate the reward points that are set to expire to sustainable activities.

Abstract: The present disclosure relates to systems for identifying instances of natural language input, determining intent classifications associated with instances of natural language input, and generating responses based on the determined intent classifications. In particular, the disclosed systems intelligently identify and group instances of natural language input based on characteristics of the user input. Additionally, the disclosed systems determine intent classifications for the instances of natural language input based message queuing in order to delay responses to the user input in ways that increase accuracy of the responses, while retaining a conversational aspect of the ongoing chat. Moreover, in one or more embodiments, the disclosed systems generate responses utilizing natural language.
