In this paper a new wavelet shrinkage technique is proposed and investigated. When data consist of a multiplicity of related noisy signals, we propose a wavelet-based shrinkage estimation procedure to summarize all data components into a single regularized and representative signal...

In this article we present a framework describing the world foreign exchange market in terms of differential geometry on graphs, that is, in terms of vector lattice bundles on graphs and connections on these bundles. This framework is based on the concept of financial equivalence introduced by...

We study the effect of a time-periodic, lateral acceleration on the two-dimensional flow of a fluid with a free surface subject to surface tension, confined between two plane, parallel walls under conditions of zero gravity. We assume that the velocity of each contact line is a prescribed,...

The is the problem of searching for a mobile intruder in a simple polygon by a mobile searcher. The objective is to decide whether there exists a for the searcher to detect the intruder, no matter how fast he moves, and if so, generate a search schedule. A searcher is called the if he holds...

We show that it is decidable for any given ground term rewrite systems and if there is a ground term rewrite system such that . If the answer is yes, then we can effectively construct such a ground term rewrite system . In other words, for any given finitely generated congruences and over the...

Given a finite set of points two measures of the depth of a query point with respect to are the of Liu and the of Tukev (also known as ). We show that computing these depths requires Ω(log ) time, which matches the upper bound complexities of the algorithms of Rousseeuw and Ruts. Our lower...

We obtain an analytical expression for the power forward prices in the case when the dynamics of the power spot prices with spikes is described by the non-Markovian stochastic process introduced earlier by the author. We also show how the power forward prices do not exhibit spikes while the...

The MATLAB algorithm mixed.m estimates the parameters of the mixed linear model by using the Henderson's MMEs (mixed model equations) algorithm, for more details see Searle et al. (1992, pp. 275-286).The algorithm computes the BLUE or the two-stage GLSE, the BLUP or the EBLUP, and the ML, REML,...
