abbot is the hybrid connectionist hidden Markov model (HMM) large vocabulary continuous speech recognition system developed at Cambridge University Engineering Department. abbot makes e ective use of the linear input network (LIN) adaptation technique to achieve speaker and channel adaptation. Although the LIN is e ective at adapting to new speakers or a new environment (e.g. a di erent microph...

A unitary signal transformation that is covariant by translation to scale changes (di-lations and compressions) in the signal is formulated and justiied. Unlike the Mellin transform, which is invariant to scale changes, this new transform is a true indicator of the scale content of a signal.

Mathematical algorithms offer a useful method for quantitative analysis of compounds in multi-component mixtures to overcome the overlapping problems occurred in UV spectrophotometry. The aim of this study is to develop a method to determine the bioactive compounds in herbal dosage forms produced from fenugreek extract. A UV- spectrophotometric method based on mathematical algorithm was used to...

Abstract— A new non-separable 2D structure is proposed for integer implementation of a 3D lifting wavelet transform. It reduces total amount of rounding noise due to expressing signal values as integers inside the transform. In the existing method, a non-separable 3D structure is used to minimize lifting steps. It contributes to decrease delay from input to output. As it decreases total number ...

In this work a Discrete Cosine Transform (DCT)-based feature dimensionality reduced approach for fingerprint matching is proposed. The DCT is applied on a small region around the core point of fingerprint image. The performance of our proposed method is evaluated on a small database of Bologna University and two large databases of FVC2000. A dimensionally reduced feature vector is formed using ...

The High Efficiency Video Coding has a significant compression performance benefit versus previous standards. Thanks to the high efficiency prediction tools, blocks with all-zero quantized transform coefficients are quite common in HEVC. The computation load of transform and quantization can be remarkably reduced if the all-zero blocks can be detected prior to transform and quantization. Based ...

The Hough transform is a popular method for detecting complex forms in digital images. However, the technique is not very robust since several parameters that determine the scope of the detection results, such as quantization thresholds and intervals, must first be defined. In the present paper, we propose to enhance shape detection with the Hough transform through fuzzy analysis. One chief dra...

abstract: in this paper, nonlocal euler–bernoulli beam theory is employed for transverse vibration analysis of an initially pre-stressed size-dependent rotating nanotube. the nonlocal eringen theory takes into account the effect of small size, which enables the present model to become effective in the analysis and design of nanosensors and nanoactuators. governing equations are derived through ...
