The objective of this research work is to extend the scope empirical mode decomposition (EMD) algorithm, as an efficient tool decompose nonlinear and non-stationary time series. For EMD be widely applicable, extension utilizes both clean noisy data sets. When constructing upper lower envelopes, proposed algorithm Akima spline interpolation technique rather than a cubic spline. called Akima-EMD,...

This work presents a technique for the chirality (n, m) assignment of semiconducting single wall carbon nanotubes by solving a set of empirical equations of the tight binding model parameters. The empirical equations of the nearest neighbor hopping parameters, relating the term (2n, m) with the first and second optical transition energies of the semiconducting single wall carbon nanotubes, are ...

Recently, a technique based on pseudo-observations has been proposed to tackle the so called convex hull problem for the empirical likelihood statistic. The resulting adjusted empirical likelihood also achieves the highorder precision of the Bartlett correction. Nevertheless, the technique induces an upper bound on the resulting statistic that may lead, in certain circumstances, to worthless co...

Uniform ratio limit theorems for empirical processes by David Pollard Statistics Department Yale University Box 208290 Yale Station New Haven, CT 06520-8290 Email: [email protected] September 1993 Revised: October 1993 Second revision: January 1995 Abstract. Analysis of nonparametric estimators is easier if one makes use of re ned empirical process inequalities. These inequalities have not ...

Polydimethylsiloxane (PDMS) is commonly used as the coated polymer in the solid phase microextraction (SPME) technique. In this study, the partition coefficients of organic compounds between SPME/PDMS and the aqueous solution were compiled from the literature sources. The correlation analysis for partition coefficients was conducted to interpret the effect of their physicochemical properties an...

The problem of filtering low-frequency trend from a given time series is considered. In order to solve this problem, a nonparametric technique called empirical mode decomposition trend filtering is developed. A key assumption is that the trend is representable as the sum of intrinsic mode functions produced by the empirical mode decomposition (EMD) of the time series. Based on an empirical anal...

The paper introduces a new technique for compressing Binary Decision Diagrams in those cases where random access is not required. Using this technique, compression and decompression can be done in linear time in the size of the BDD and compression will in many cases reduce the size of the BDD to 1-2 bits per node. Empirical results for our compression technique are presented, including comparis...

Elicitation is the study of statistics or properties which are computable via empirical risk minimization.While several recent papers have approached the general question of which properties are elicitable, wesuggest that this is the wrong question—all properties are elicitable by first eliciting the entire distributionor data set, and thus the important question is how elicitable. ...

The lifetime of the b Pu(v51) state in N2 has been determined experimentally using a laser-based pump–probe scheme and an exceptionally long lifetime of 2.61 ns was found. Semiempirical close-coupling calculations of the radiative lifetime, which include Rydberg–valence interactions in the singlet manifold, are consistent with this large value, giving a value of 3.61 ns and suggesting a prediss...

We describe our entry in the EMNLP 2014 code-switching shared task. Our system is based on a sequential classifier, trained on the shared training set using various characterand word-level features, some calculated using a large monolingual corpora. We participated in the Twitter-genre Spanish-English track, obtaining an accuracy of 0.868 when measured on the tweet level and 0.858 on the word l...
