This paper examines the forward masking on the generalized logarithmic scale for robust speech recognition to both additive and convolutional noise. The forward masking in the dynamic cepstral (DyC) representation is based upon subtraction of a masking pattern from a current spectrum on a logarithmic spectral domain, whereas the proposed method intends to make a compromise between the logarithm...

The purpose of this study was to investigate digital subtraction technique in digital dental imaging for implant performance, used to quantitatively evaluate bone change around dental implants. For longitudinal assessment of peri-implant bone change, we applied subtraction technique to digital peri-apical radiographs using a digital dental imaging system in two cases at the upper canine and pre...

This paper describes a simple and efficient method of colour image compression/decompression using the fundamental application of subtraction and formation of a dynamic dictionary after three stages of subtraction. Pixels in different segments generated by a chosen mask window are adjusted such that after three stages of subtraction, either all zero or at most one non-zero element is left. The ...

This paper tells the technique for low power addition/subtraction of Logarithmic number system (LNS). Firstly, the impact of partitioning the look up tables (LUT) required for addition/subtraction on complexity, performance is studied. Two design parameters namely organisation of word and base are also taken into consideration. For addition and subtraction of LNS, MATLAB is also used to calcula...

We propose a novel method to measure time-dependent linear susceptibilities in molecular simulations, which does not require the use of nonequilibrium simulations, subtraction techniques, or fluctuation-dissipation theorems. The main idea is an exact reformulation of linearly perturbed quantities in terms of observables accessible in a single unperturbed trajectory. We apply these ideas to supe...

With the use of a double stimulus technique, nerve fibre velocity range measurements were performed over a single conduction distance in 13 normal subjects and over two conduction distances in another 12 normal subjects. The velocity ranges were found to be dependent upon the conduction distance, owing to unknown refractory period delays. Refractory period values were calculated for the 12 subj...

The Nearby Supernova Factory (SNfactory) is an ambitious project to find and study in detail approximately 300 nearby Type Ia supernovae (SNe Ia) at redshifts 0.03 < z < 0.08. This program will provide an exceptional data set of well-studied SNe in the nearby smooth Hubble flow that can be used as calibration for the current and future programs designed to use SNe to measure the cosmological pa...

Chromatographers are cautioned to avoid gradient elution when isocratic elution will do. In this work, we compared the analytical properties of gradient and isocratic separations of a sample which can be done quite readily under isocratic conditions. We found that gradient elution gave a shorter overall analysis with similar resolution of the critical pair compared to isocratic elution without ...

We used the event-related potential (ERP) approach combined with a subtraction technique to explore the timecourse of activation of semantic and phonological representations in the picture-word interference paradigm. Subjects were exposed to to-be-named pictures superimposed on to-be-ignored semantically related, phonologically related, or unrelated words, and distinct ERP waveforms were genera...

Internal multiples have long been recognized as a problem in seismic imaging. Some theoretical developments have been made to attenuate them, but there is no 3D theory as yet that is valid for a wide range of velocity models. The goal of this paper is to present such a theory. Through the development of this theory we show that, unless certain simplifying assumptions are made about the velocity...
