Abstract: Described is a technology by which a roadside-to-vehicle communication system may be implemented, including via a stateful scheduling with network coding scheme that enhances network capacity. Moving vehicles request and receive data from a roadside access points. Each of the access points operate a stateful scheduling algorithm that serves multiple vehicles by integrating network coding within a timeslot. In one aspect, the state of each vehicle's previously received and retained data is obtained, and used to enhance network capacity by combining as many packets as possible for multiple recipients in network coding.

Abstract: Described is continuous network coding, in which a relay sends probability data comprising a continuous number for use as parity data. The node receives streams of bits sent from sources towards a destination, and computes the probability data based on current noise data and/or fading data. A selected set of the bits (all or some subset thereof) are combined, e.g., XOR-ed or concatenated, and send to the destination. Phase modulation is performed to convey probability information based on the probability data. The destination demodulates the signal to obtain the probability information, and combines the probability information with the data directly received from sources to perform joint decoding. The number of bits in the set of selected bits may be adaptively chosen based on current channel conditions, e.g., increased when the channel conditions from the sources directly to a destination are poor relative to the channel conditions via the relay.

Abstract: A method of reducing oxide thickness variations in a STI pattern that includes both a dense trench array and a wide trench is described. A first HDP CVD step with a deposition/sputter (D/S) ratio of 9.5 is used to deposit a dielectric layer with a thickness that is 120 to 130% of the shallow trench depth. An etch back is performed in the same CVD chamber with NF3, SiF4 or NF3 and SiF4 to remove about 40 to 50% of the initial dielectric layer. A second HDP CVD step with a D/S ratio of 16 deposits an additional thickness of dielectric layer to a level that is slightly higher than after the first deposition. The etch back and second deposition form a smoother dielectric layer surface which enables a subsequent planarization step to provide filled STI features with a minimal amount of dishing in wide trenches.

Abstract: A novel multi-resolution block sampling based texture analysis/synthesis algorithm. A reference texture is assumed to be sample from a probability function. The synthesis of a similar, but distinctive, synthetic texture is handled in a process and by an apparatus that first estimates and then resamples the probability function. In order to achieve good and fast estimation of the probability function for a reference texture and in order to retain the texel structural information during the synthesis, a novel concept of block sampling and a corresponding novel texture synthesis scheme based on multi-resolution block sampling is employed. As a result of this novel approach, the computational complexity of the present invention is much lower than that of other approaches to the problem. In addition, for textures that exhibit a high degree of directionality, a process, which integrates estimation of dominant texture direction and the synthesis algorithm is employed to handle directional textures.
