the aim of this paper is to evaluate suppliers using a multi objective programming problem and multiple criteria data envelope analysis. toward accomplishing this goal, first a general algorithm is introduced to obtain a continuous set of efficient solutions of the given multi objective programming problem. then, since each member of such set can be viewed as a combination of inputs such as raw...

Humans are highly adept at processing speech. Recently, it has been shown that slow temporal information in speech (i.e., the envelope of speech) is critical for speech comprehension. Furthermore, it has been found that evoked electric potentials in human cortex are correlated with the speech envelope. However, it has been unclear whether this essential linguistic feature is encoded differentia...

Similarity Indexing is very important for content-based retrieval on large multimedia databases, and the "tightness" of data set envelope is a factor that influences the performance of index. For equidistant envelope (bounding sphere), calculation of envelope is somewhat difficult because of the complexity of direct computation in high dimension space. In this paper we summarize the envelope us...

In this paper, envelope detection of speech is discussed to distinguish the pathological cases of speech disabled children. The speech signal samples of children of age between five to eight years are considered for the present study. These speech signals are digitized and are used to determine the speech envelope. The envelope is subjected to ratio mean analysis to estimate the disability. Thi...

We present applications of variational – wavelet approach to nonlinear (rational) rms envelope dynamics. We have the solution as a multiresolution (multiscales) expansion in the base of compactly supported wavelet basis.

March 22, 1994 A wealthy eccentric places two envelopes in front of you. She tells you that both envelopes contain money, and that one contains twice as much as the other, but she does not tell you which is which. You are allowed to choose one envelope, and to keep all the money you find inside. This may seem innocuous, but it generates an apparent paradox. Say that you choose envelope 1, and i...

A new approach for frequency analysis of recorded signals and readout the frequency of harmonics is presented in the paper. The main purpose has been achieved by the cross-correlation function and Hilbert transform. Using the method presented in the paper, there is another possibility to observe and finally to identify single harmonic apart from commonly used Fourier transform. Identification o...

Proteomic analysis on cell envelope proteins from Gram-negative bacteria requires specific isolation techniques. We found that conventional extraction methods such as osmotic shock cause extracts to be heavily contaminated with soluble cytoplasmic proteins. These cytoplasmic protein contaminants constitute the major signal in proteomic analysis and can overwhelm the signals coming from genuine ...

Although the human hCCR-5 chemokine receptor can serve as a co-receptor for both M-tropic (ADA and BaL) and dual-tropic (89.6) strains of human immunodeficiency virus type 1 (HIV-1), the closely related mouse mCCR-5 homolog is inactive. We used chimeric hCCR-5-mCCR-5 receptor molecules to examine the functional importance of the three extracellular domains of hCCR-5 that differ in sequence from...

SUMMARY EchoLOCATION is a database that provides a comprehensive analysis of the subcellular locations of Escherichia coli K-12 proteins. Locations are predicted by integrating data from a range of publicly available algorithms combined with extensive curation of experimental literature. The data can be searched in a variety of ways and can generate lists of subcellular proteomes for analysis. ...
