[1] This paper uses sequential Bayesian techniques such as particle filters and smoothers to track in time both the non-volcanic tremor (NVT) source location on the plate interface and the angle of arrival via horizontal phase slowness. Sequential Bayesian techniques enable tracking of evolving geophysical parameters via sequential tremor observations. These techniques provide a formulation whe...

Most of the serious handicaps of childhood present long before the age of 3 years. In the 3 to 5 year age group the commonest cause for concern is that the child is progessing more slowly than his peers, either in acquisition of language, motor coordination, or in all aspects of development. The purpose of this paper is firstly to review the concept of 'slowness', and then to discuss the paedia...

In an important paper Hinton and Nowlan demonstrate the Baldwin e ect in a simple Genetic Algorithm The ability of the phenotype to adapt coupled with the evolu tionary process allows behavioural goals to become over time genetically speci ed this seems Lamarckian but is not In that paper as a subsidiary point the slowness of xa tion of the last few goals is commented on and a later paper by Be...

Among the adaptive-grid methods, redistribution and embedding techniques have been the focus of more attention by researchers. Simultaneous or combined adaptive techniques have also been used. This paper describes a combination of adaptive-grid embedding and redistribution methods on semi-structured grids for two-dimensional invisid flows. Since the grid is semi-structured, it is possible to us...

We present a novel formula for Gaussian Berezin correlation functions. A formula well known in the literature expresses these quantities in terms of submatrices of the inverse matrix appearing in the Gaussian action. Our formula allows one to evaluate these integrals without calculating the inverse of the matrix. The derivation of the formula is obtained via a recently proposed method to calcul...

Consider approximating functions based on a finite number of their samples. We show that adaptive algorithms are much more powerful than nonadaptive ones when dealing with piecewise smooth functions. More specifically, let F 1 r be the class of scalar functions f : [0, T ] → R whose derivatives of order up to r are continuous at any point except for one unknown singular point. We provide an ada...

in this paper we introduce a simple, computationally inxepentsive, adaptive recursive structure for enhancing bandpass signals highly corrupted by broad-band noise. this adaptive algorithm, enhancing input signals, enables us to estimate the center frequency and the bandwidth of the input signal. in addition, an important feature of the proposed structure is that the conventional bias existing ...
