Abstract: An interconnection network for a processing unit having an array of cores. The interconnection network includes routers and adaptable links that selectively connect routers in the interconnection network. For example, each router may be electrically connected to one or more of the adaptable links via one or more multiplexers and a link controller may control the multiplexers to selectively connect routers via the adaptable links. In another example, adaptable links may be formed as part of an interposer and the link controller selectively connect routers via the adaptable links in the interposer using interposer switches. The adaptable links enable the interconnection network to be dynamically partitioned. Each of those partitions may be dynamically reconfigured to form a topology.

Abstract: A multi-laminar electrospun nanofiber scaffold for use in repairing a defect in a tissue substrate is provided. The scaffold includes a first layer formed by a first plurality of electrospun polymeric fibers, and a second layer formed by a second plurality of electrospun polymeric fibers. The second layer is combined with the first layer. A first portion of the scaffold includes a higher density of fibers than a second portion of the scaffold, and the first portion has a higher tensile strength than the second portion. The scaffold is configured to degrade via hydrolysis after at least one of a predetermined time or an environmental condition. The scaffold is configured to be applied to the tissue substrate containing the defect, and is sufficiently flexible to facilitate application of the scaffold to uneven surfaces of the tissue substrate, and to enable movement of the scaffold by the tissue substrate.

Abstract: A sensor system includes a sensor module that is embedded in a target environment and a signal system. The sensor module includes an active sensor of a first type that detects a target element in the target environment and a reference sensor of the first type that prevents detection of target elements by the reference sensor. The active sensor and the reference sensor receive an ultrasonic signal and respectively generate a first response signal and a second response signal. The first response signal is at least partially as a function of the detected target element. The signal system includes an ultrasonic transducer that generates the ultrasonic signal and receives the first and second response signals, and a controller communicatively coupled to the ultrasonic transducer. The controller identifies the detected target element based at least partially on the first and second response signals.
Abstract: A modular micro-cathode arc thruster for use in satellites. An exemplary satellite has a plurality of stacked modular arc thrusters, each having an external anode, an internal cathode, and an insulator therebetween. The arc thrusters are situated in a housing, wherein the housing has an opening to eject exhausted thrusters. Once an arc thruster is expended, the push rod ejects that arc thruster and the next arc thruster takes its place.

Abstract: Cloud simulation or validation system allows for the simulation of a future node that may be deployed on a piece of hardware. The system may attempt to simulate the operating system for node-A on top of the hardware for node-A, including basic network connectivity. When a host is booted up with the simulated configuration, validation scripts may be run to verify that the site is correctly prepped for cloud deployment. With its pre-staged RAM-based OS temporarily loaded into the host's RAM memory, any set of OS-based scripts, tools or binaries, may be executed for simulation and validation based upon the intended role of the host onto which the cloud simulation or validation system configuration is loaded.

Abstract: Software-based data planes for network function virtualization may use a modular approach in which network functions are implemented as modules that can be composed into service chains. Infrastructures that allow these modules to share central processing unit resources are particularly appealing since they support multi-tenancy or diverse service chains applied to different traffic classes. Systems, methods, and apparatuses introduce schemes for load balancing considering central processing unit utilization of a next hop device when processing a packet that uses a service chain.
