Abstract: System for adaptive routing in time division multiple access-based wideband mobile adhoc network employs an enhanced OLSR-based routing protocol designed for TDMA-based mobile adhoc network to spread the link quality information and calculates adaptive routing paths based on the link quality. The system employs a signal-to-noise ratio calculation, demodulation and decoding block, link quality estimator, FIFO, link quality broadcast, network layer link state broadcast, link state table, adaptive routing, path calculation block and routing table blocks to achieve the desired results.

Abstract: A system and method for live video streaming over tactical wireless networks based on distortion estimation using multilayer perceptron neural network (MLP). The system and method can adaptively adjust the parameters of transport and application layers according to wireless network conditions, based on video distortion estimation using MLP neural network. The system includes a video motion and detail estimation block, a redundancy and video bitrate optimizer, a MLP neural network-based video distortion estimator, and video transport blocks, a packet error rate (PER) and bandwidth measurement block.

Abstract: In an event-driven architecture, at design time a central catalog allows event consumer(s) to reconstruct an event structure for later processing during runtime. The central event catalog receives from a publisher (of an event producer), an event description document specifying an event identifier, source code of an event class extracted from an event, and an annotation. This event description document is stored by the catalog as a central instance in a database. Upon receiving a query from an event consumer regarding the event, the event description document is returned as a query result. A code generator (of the event consumer) creates the event structure from the event description document, allowing processing of the event. Embodiments are particularly suited to centrally locate a single, up-to-date instance of an event description document, for reference in allowing multiple consumers of an event to accurately reproduce the latest version the structure of that event.

Abstract: A calibration of an unmanned aerial vehicle is performed without the use of a magnetometer. The unmanned aerial vehicle generates a first acceleration vector in a navigation frame of reference and a second acceleration vector in a GPS frame of reference. The unmanned aerial vehicle estimates a heading of the unmanned aerial vehicle based on the first acceleration vector and the second acceleration vector. The unmanned aerial vehicle performs a calibration based on the estimated heading of the unmanned aerial vehicle.

Abstract: The method for drawing a fiber with a textured surface comprises the following steps: —forming of a preform from which the fiber is to be drawn with a textured surface; —addition of an outer layer to the textured preform to preserve the shape of the texture of the preform surface during the drawing operation; —drawing of a fiber from the preform, whereby the fiber keeps the formed texture of the preform surface and —removing the additional outer layer to leave the original surface textured fiber exposed. The obtained fiber can be used as a mold to form a textured hollow channel in another material, as a surface coating and as a pressure detector.

Abstract: An embodiment of the present invention is a technique to stack multiple devices using an interconnecting element. A board has a periphery and top and bottom surfaces. The top surface has top contact pads to attach to a first device. The bottom surface is milled down to form a cavity confined by vertical walls around the periphery. The cavity fits a second device. Bottom contact pads are formed on bottom side of the vertical walls. The bottom contact pads are raised with respect to the bottom side of the vertical walls. Traces internal to the board connect the bottom contact pads to the top contact pads.
