Modification of the silanophilic activity of the inner surface of the capillary wall was studied in a capillary electrophoretic system using alkylamines containing background electrolytes at acid pH. The effect of the following amine additives was investigated: (1) alkyl-alpha,omega-diamines (1,2-diaminoethane, 1,4-diaminobutane, 1,7-diaminoheptane, spermine), (2) polymeric amines (polyethyleni...

Several versions of a moving mesh method are developed based on a mesh spatial smoothing technique and on the moving mesh PDEs derived in a previous paper. These versions are quite simple and easy to program. They are applied to three benchmark one-dimensional problems which show diierent solution behaviour. The numerical results clearly demonstrate that the present methods are capable of accur...

In this paper a novel approach for detection of peaks in spectral representations of music signals is proposed. The basic idea is to detect local maxima in any digitized signal and employ statistical techniques for filtering out spurious peaks which are the result of imperfections and noise in spectral representations of music signal.

The paper constructs various core inflation measures. These include various trimmed means using disaggregated data and a structural VAR estimate of core inflation for Ireland. The ability of these core inflation measures to forecast future headline inflation is compared using a regression model. An ARIMA model fitted to the headline inflation rate is used as the benchmark forecast. The forecast...

Using the spectral regression method, we test for long-term stochastic memory in threeand six-month daily returns series of Eurocurrency deposits denominated in major currencies. Significant evidence of positive long-term dependence is found in several Eurocurrency returns series. Compared to benchmark linear models, the estimated fractional models result in dramatic out-of-sample forecasting i...

This paper explores how to find, track, and learn models of arbitrary objects in a video without a predefined method for object detection. We present a model that localizes objects via unsupervised tracking while learning a representation of each object, avoiding the need for pre-built detectors. Our model uses a dependent Dirichlet process mixture to capture the uncertainty in the number and a...

Control parameters of original differential evolution (DE) are kept fixed throughout the entire evolutionary process. However, it is not an easy task to properly set control parameters in DE for different optimization problems. According to the relative position of two different individual vectors selected to generate a difference vector in the searching place, a self-adapting strategy for the ...

Location-based services (l-services for short) compose an emerging application involving spatiotemporal databases. In this paper, we discuss this type of application, in terms of database requirements, and provide a set of ten benchmark database queries (plus two operations for loading and updating data). The list includes selection queries on stationary and moving reference objects, join queri...
