    摘要: Stimulating power line carrier injection with reactive oscillation comprises exciting a tank circuit to oscillate at the carrier frequency by sinking pulses of current between one node of a capacitor in the tank circuit and the other node of the capacitor. A power transformer is connected to a distribution system to inject a power line carrier onto the power line. An excitation circuit sinks short pulses of current between one node of a capacitor and the other node of the capacitor that is connected in a tank circuit arrangement with an inductor and the secondary winding of the power transformer. The tank circuit oscillates at the frequency of the excitation pulses if the resonant frequency of the tank circuit is close to the frequency of excitation. The oscillating current is coupled onto the power line system through the power transformer. The phase of the power line carrier signal is shifted by shifting the phase of the excitation pulses.

    摘要: Selectivity estimates are produced that meet a desired confidence threshold. To determine the confidence level of a given selectivity estimate for a query expression, the query expression is evaluated on a sample tuples. A probability density function is derived based on the number of tuples in the sample that satisfy the query expression. The cumulative distribution for the probability density function is solved for the given threshold to determine a selectivity estimate at the given confidence value.

    摘要: The present invention relates generally to grids for gating a stream of charged particles and methods for manufacturing the same. In one embodiment, the present invention relates to a Bradbury-Nielson gate having transmission line grid elements. In one embodiment is a feed structure for a gating grid where a drive source is coupled to a feeding transmission line with the same geometry as the chopper and continues with the same geometry to a termination transmission line. Also included is a method for fabricating a gate for charged particles which includes micromachining at least two gate elements from at least one wafer, wherein each gate element includes at least one grid element; metalizing the grid elements; and assembling the gate elements such that the grid elements of the gate elements are interleaved, thereby forming a Bradbury Nielson gate.

    摘要: Compositions and methods effective in inhibiting abnormal or undesirable cell proliferation, particularly endothelial cell proliferation and angiogenesis related to neovascularization and tumor growth are provided. The compositions comprise peptide molecules, optionally containing one or more individual peptide chains covalently linked, and optionally modified with polyethylene glycol (PEG). The methods involve administering to a human or animal the composition described herein in a dosage sufficient to inhibit cell proliferation, particularly endothelial cell proliferation. The methods are useful for treating diseases and processes mediated by undesired and uncontrolled cell proliferation, such as cancer, particularly by inhibiting angiogenesis. Administration of the composition to a human or animal having prevascularized, metastasized tumors is useful for preventing the growth or expansion of such tumors.

    摘要: A computer implemented method of underwriting profitability analysis delivers the analytic process to a wide cross section of insurance decision makers. The underwriting profitability analysis system leverages an existing investment in databases and improves underwriting business processes. Data mining techniques are applied to historical policy and claims to extract rules that describe policy holders with homogeneous claim frequency and severity characteristics. These rule sets are used to classify policy holders into distinct risk groups, each with its own set of characteristics, including pure premium. Breaking up a book of business into segments allows identification of sub-populations of policy holders that distinctly deviate from the expected normal pure premium. This identification allow the insurance business analysts to interactively adjust eligibility criteria and examine altered characteristics of the covered segments until satisfactory. The system is implemented on a client server using network centric language technology.
