We present the calculation of noise expressions of low voltage amplifiers by applying symbolic nodal analysis and using nullors. The nullor equivalents of the MOSFETs include only the dominant parasitic elements in order to generate a simplified symbolic noise expression, which provides a good insight to improve the design of low voltage amplifiers. The generated symbolic noise expressions are compared...
At present, most of the studies on the relationship between El Nino Southern Oscillation and agricultural futures focus on perceptual and directly data analysis. This article uses EMD algorithm on endpoints processed data to decompose wheat futures price into seven Intrinsic Mode Function and one Residue. Then do symbolic clustering combined with SSVS method and denoised ENSO index. The results not...
A two-step identification method for nonlinear polynomial model using Evolutionary Algorithm (EA) is proposed in this paper, and the method has the ability to select a parsimonious structure from a very large pool of model terms. In a nonlinear polynomial model, the number of candidate monomial terms increases drastically as the order of polynomial model increases, and it is impossible to obtain the...
In this paper, a novel method for image registration method which affords robust results for various disturbances in the real world, including local and/or global variations of illumination, occlusions, and noises, is proposed. The registration process is based on a set of selected point-pairs with binary coded signs of differences, which is constructed from the given template image. The selection...
In this article we propose a technique to detect the reference point of a fingerprint based on the main supposition that the crests belonging to the superior area of reference point usually have a orientation quantized of 0??. To take advantage of this fact it is accomplished an analysis of the orientation image considering their multiple levels of representation in relation to their values of quantization...
