A system and method for analyzing an input signal comprising one or more sinusoidal tones. A processor of the system receives samples of an input signal and operates on the samples to generate a transform array. The processor identifies positive frequency peaks of the transform array, and estimates a set of signal parameters (e.g. tone frequency and complex amplitude) for each of the positive frequency peaks. Each tone is represented in the transform array as a positive frequency image and a corresponding negative frequency image. Using the parameter sets, the processor may estimate the amount of cross-interaction between the images, i.e., may compute the amounts by which each positive frequency peak is effected by the negative frequency images and other positive frequency images. These amounts may be subtracted from each positive frequency peak to generate improved peak values. The processor may use the improved peak values to compute improved estimates for the signal parameters. The operations of (a) estimating the cross-interaction amounts based on current parameter estimates for the multiple tones, (b) subtracting the cross-interaction amounts from the current peak values to generate improved peak values for each tone, and (c) computing improved parameter estimates for the multiple tones from the improved peak values may be repeated a predefined number of time or until a termination criteria is achieved.

A neural network resource sizing apparatus for database applications. Through use of multiple database application metrics input into a neural network learning algorithm, recommended resource capacities are generated. Input parameters such as the number of records, lookups, images, PDFs, fields, BLOBs and width of fields for example may be utilized to train a neural network to yield needed resource metrics such as the processing power, memory, disk and / or network capacities required to run the database application. Training for the neural network may involve running tests over all desired cross interactions of input and output parameters beginning for example with a small repository and ending with the maximum complexity of data and schema test. The training data is input into the neural network for the given database application version and utilized to plan resource utilization. A portal or webservice may be utilized to provide an interface to the apparatus.

The invention belongs to the technical field of pavement and maintenance of roads and bridges, and discloses a method for paving an assembled bridge deck of a long-span steel bridge. The step of surface; the step of processing the steel bridge deck matched with each grid of the modularized steel bridge deck; the step of hoisting the steel bridge deck on the modularized steel bridge deck and fixedly connecting with the steel box girder. The pavement method of the present invention has the advantages of factory production and molding, excellent quality and high precision, can avoid the defects of traditional steel bridge deck pavement, is simple and easy to implement, improves the efficiency of modular construction, shortens the cycle, and distributes human resources evenly. There is no cross-interaction in the process, and the proposal of the assembled steel bridge structure solves the integrity of the bridge deck, the stability and comfort of driving after block installation, the sealing of the joints, and the coordination with the deformation and stress of the steel box girder structure, etc. series of questions.
