The method includes spraying a deposition mixture of a first composition and a second composition via a solution precursor plasma spray apparatus onto a surface of a substrate; while spraying the deposition mixture, adjusting at least one deposition parameter such that the thermal barrier coating is formed with the non-linear gradient.

Abstract: A leaky-mode acousto-optical modulator may be used to generate visual images suitable for direct viewing, without image-forming optics. To extend a field of view of the modulator to limits suitable for visual displays, an array of acoustic transducers is coupled to a waveguide along its length. Each acoustic transducer generates an acoustic wave causing a corresponding leaky mode to appear. A reflector is disposed proximate each transducer for directing the out-coupled light portion at a unique angle, providing a corresponding field of view portion for that direction. The field of view portions coalesce into a continuous synthetic field of view suitable for wide-angle visual display applications.

Abstract: A leaky-mode acousto-optical modulator may be used to generate visual images suitable for direct viewing, without image-forming optics. To extend a field of view of the modulator to limits suitable for visual displays, the leaky-mode acousto-optical modulator may be equipped with a switchable beam redirector, e.g. a switchable-angle reflector, providing field of view portions one by one in a time-sequential manner. The field of view portions coalesce into a continuous synthetic field of view suitable for wide-angle visual display applications.

Abstract: Techniques for combining the functionality of fabric interconnects and switches (e.g., Top-of-Rack (ToR) switches) into one network entity, thereby reducing the number of devices in a fabric and complexity of communications in the fabric. By collapsing FI and ToR switch functionality into one network entity, server traffic may be directly forwarded by the ToR switch and an entire tier is now eliminated from the topology hierarchy which may improve the control, data, and management plane. Further, this disclosure describes techniques for dynamically managing the number of gateway proxies running on one or more computer clusters based on a number of managed switch domains.

Abstract: Presented herein are systems and methods to enable simultaneous interoperability with policy-aware and policy-unaware data center sites. A multi-site orchestrator (MSO) device can be configured to obtain configuration information for each of a plurality of different data center sites. The data center sites may include one or more on-premises sites and one or more off-premises sites, each of which may include one or more policy-aware sites and/or one or more policy-unaware sites. The MSO can selectively use namespace translations to create a unified fabric across the different data center sites, enabling one or more hosts and/or applications at a first of the data center sites to communicate with one or more hosts and/or applications at a second of the data center sites, regardless of the sites' respective configurations.

Abstract: A method, a computer system, and a computer program product for communicating employment opportunities to job candidates. A recruiting system receives a job posting from an organization communicating over a first network. The recruiting system matches the job requirements in the job posting to a candidate profile. The recruiting system identifies a mobile device associated with the candidate profile, and an interaction template that describes a conversational flow of messages for soliciting an application for the job from a job candidate. A dialogue is initiated with the mobile device, by sending a transmission object built from a message in the interaction template. A response received from the mobile device based on rules that describe a conversational flow for the interaction template. If the response is positive, the recruiting system submits the user as a candidate for the job by posting the information in the response to the organization.
