Abstract: A heat exchanger positioned within an annular duct of a gas turbine engine is provided. The heat exchanger extends substantially continuously along the circumferential direction and defining a heat exchanger height equal to at least 10% of a duct height. An effective transmission loss (ETL) for the heat exchanger positioned within the annular duct is between 5 decibels and 1 decibels for an operating condition of the gas turbine engine. The heat exchanger includes a heat transfer section defining an acoustic length (Li), and wherein an Operational Acoustic Reduction Ratio (OARR) is greater than or equal to 0.75 to achieve the ETL at the operating condition.

Abstract: Apparatuses, computer readable media, methods, and systems are described for requesting creation of virtual machine (VM) in a cloud environment comprising a virtual private cloud. Through various communications between a cloud DMZ, cloud provider, and/or company's network, a VM instance may be securely created, initialized, booted, unlocked, and/or monitored through a series of interactions building, in some examples, upon a root of trust.

Abstract: Apparatuses, computer readable media, methods, and systems are described for storing a first measurement of a virtualization platform, storing a second measurement of a measured virtual machine, generating a quote using a key, wherein the quote is based on the first measurement and the second measurement, and providing the quote for attesting to authenticity of the virtualization platform and of the measured virtual machine. In a further example, the quote may be generated based on a third measurement of a secure tunnel.

Abstract: Apparatuses, computer readable media, methods, and systems are described for generating and communicating a create measured virtual machine (VM) request, the request comprising a network address of a boot server, initiating establishment of a secure tunnel with a measured VM, receiving a quote from the measured VM, and determining, by a processor, whether the measured VM is authentic based on the quote.

Abstract: An architecture record can be created for a computer system that includes a plurality of computing devices, each having an operating system. The architecture record includes platform definition architectures each associated with one of the computing devices and the operating system of the computing device, domain reference architectures each associated with one or more of the platform definition architectures and a service performed by the computing device of each platform definition architecture, and channel reference architectures each associated with one or more of the domain reference architectures, wherein the computing devices associated with the one or more domain reference architectures are configured to communicate with each other while performing the respective services associated with the one or more domain reference architectures.

Abstract: A reversible belt and method of manufacture in which an elongated strip of fabric is folded over and around a strip of filler material to form a belt section and two such sections are stacked in opposing relationship with a strip of a reinforcing material therebetween. The belt sections with the intermediate strip of material are joined together by a row of stitches along each edge of the belt with the stitches passing through the fabric of the sections and the reinforcing material.
