Efficient algorithms for bichromatic separability
ACM Transactions on Algorithms, 2006A closed solid body separates one point set from another if it contains the former and the closure of its complement contains the latter. We present a near-linear algorithm for deciding whether two sets of n points in ℝ 3 can be separated by a prism, near-quadratic ...

Efficient Implementation of Separability Criteria
Journal of the Physical Society of Japan, 2003Entanglement is a valuable resource in quantum information processing and thus its detection and characterization is an important procedure. We review some of the criteria for separability and provide an efficient and physically realizable method by which entanglement may be detected within the “distant labs” paradigm.

An Efficient DCA for Spherical Separation
2011The binary classification problem consists in finding a separating surface minimizing an appropriate measure of the classification error. Several mathematical programming-based approaches for this problem have been proposed. The aim of spherical seperation is to find, in the input space or in the feature space, a minimal volume sphere separating set A ...

Separation Power and Separation Efficiency of Pulse Cascades
Separation Science and Technology, 2011Pulse cascades are non-conventional and may suit the flexible demand for stable isotopes varying in varieties and quantities. The separation power in pulse cascades is evaluated, and the definitions and the expressions of the separation efficiency are given respectively.

Tests and efficiencies of separate regression models
Biometrika, 1978SUMMARY The results of Cox (1961, 1962) on tests of separate families of hypotheses are used to develop tests for some log linear regression models. The consequences of using one model when another is true are studied. The probability limits and asymptotic efficiencies of the estimators of the regression coefficients when using a false model in ...

Thermodynamic efficiency of thermoacoustic mixture separation
The Journal of the Acoustical Society of America, 2002The acoustic power loss in the thermoacoustic mixture-separation process is derived, including the contributions due to a nonzero gradient in concentration. The significance of the gradient-dependent term is discussed. The limiting thermodynamic efficiency of the separation is calculated.

An efficient wavelet dictionary for texture separation
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007In this paper, our goal is to highlight the importance of the source separation method on remote sensing data analysis when dealing with urban areas characterized by spatial concept like texture. Source separation has become an attractive tool used to compensate physical information deficiency by statistical assumptions. The method's key comes from the

In the previous chapter we have examined various models for predicting the velocity distributions in cyclones. In this chapter we wish to first present a brief discussion of the issues, and to then present some of the literature models available for computing cyclone separation efficiency.

A magnetic separator for efficient microalgae harvesting
Bioresource Technology, 2014A magnetic separator, which consisted of permanent magnet drum, separation chamber and scraper blade, was manufactured for efficient microalgae harvesting. The harvesting efficiency of Chlorella ellipsoidea cells reached more than 95% within forty seconds in each batch operation of microalgae harvesting.

I/O-Efficient Planar Separators
SIAM Journal on Computing, 2008We present I/O-efficient algorithms for computing optimal separator partitions of planar graphs. Our main result shows that, given a planar graph $G$ with $N$ vertices and an integer $r > 0$, a vertex separator of size O$(N / \sqrt{r})$ that partitions $G$ into O$(N / r)$ subgraphs of size at most $r$ and boundary size O$(\sqrt{r})$ can be computed in ...
