Abstract: A method and apparatus for assembling a wellscreen (50) onto a perforated base pipe (52) are provided. The wellscreen defines a tubular body which is suitable for subterranean use in oil, gas, and water wells. In accordance with the present invention, the wellscreen first defines a perforated base pipe having termination members (66) at its opposite ends. Disposed on each termination member is a continuous helical, step-tiered surface (72). The helical surface serves as a support surface for a layer of filtering material (74) which is rolled around the base pipe. The filtering material is pre-cut to a correct diameter and bias to match the diameters and bias of the spiralling termination support surfaces. The filtering material is connected to the rings to form a substantial seal on the opposite ends. A protective, perforated outer shroud is optionally disposed around the filtering media as well.

Abstract: ANN Loadflow Computation Method (LCM) is invented involving input vector composed of net nodal injected real power (P), reactive power (Q), and diagonal elements of conductance and susceptance matrices multiplied by squared initial guess node voltage magnitude (V) or sum of its real and imaginary components. Training, and testing and validating input data sets/vectors are generated by applying uniform and non-uniform scaling factors applied to base case load P and Q  at PQ-nodes, and resistance and reactance of network branches. These scale factors are increased until Loadflow Solution by a conventional LCM diverges due to V or angle (.theta.) instability. V and .theta. values in the solution just before divergence are respective stability limits, and corresponding values in Loadflow Solution provide direct measure of respective stability margins. Suresh's diakoptics based feature selection technique is presented for calculating one node variable with one neuron in each of the ANN's output layers.

Granted: 2015-12-22
Abstract: A system and methods for adapting streaming data for transmission over a connection of time-varying capacity are disclosed. A streaming server individually adapts transmission rates of signals directed to subtending clients according to measurements characterizing connections from the streaming server to the clients. The measurements may relate to characteristics such as transfer delay, data-loss fraction, and occupancy level of a buffer at a client's receiver. A flow controller associated with the streaming server derives metrics from measurements taken over selected time windows to determine a permissible transmission rate from the server to each active client. Metrics related to a specific characteristic may include a mean value over a moving window as well as short and long term tendencies of respective measurements. An adaptable encoder at the streaming server encodes signals to meet permissible transmission rates.
