We reviewed the canonical quantisation of geometry spacetime in cases a simply and non-simply connected manifold. In former, we analysed information contained solutions Wheeler–DeWitt equation showed their interpretation terms customary boundary conditions that are typically imposed on semiclassical wave functions. particular, three different paradigms for quantum creation homogeneous isotropic...

Abstract In this paper, we explore a recently emerged approach to the problem of quantisation based on notion ideals. We explicitly prove that nonabelian Volterra together with whole hierarchy its symmetries admits deformation quantisation. show all odd-degree admit also non-deformation discuss for periodic including their quantum Hamiltonians, central elements quantised algebras, and demonstra...

Vector quantization provides better ratedistortion performance over scalar quantization even for a random vector with independent dimensions. However, the design and implementation complexity of vector quantizers is much higher than that of scalar quantizers. To reduce the complexity while achieving performance close to optimal vector quantization and better than scalar quantization, we propose...

Recently, MP-LPC [1] and other similar analysis-bysynthesis (A-by-S) coding schemes have proved that it is possible to achieve very high quality coded speech down to around 8 kb/s. In this paper we report on simulation results of a multi-pulse coder with pitch prediction at bit rates of 8 kb/s and below. The effects of various long term prediction configurations have been evaluated both subject...

We examine various properties of double field theory and the doubled string sigma model in context geometric quantisation. In particular we look at T-duality as symplectic transformation related to an alternative choice polarisation construction quantum bundle for string. Following this perspective adopt a variety techniques from quantisation study space. One application is coherent state that ...

This paper recognises signals from two sources, where one is a normal person and the other is a myopathy patient. The signals under experimentation were acquired from the branchial biceps (BB) muscles using a needle electrode. This paper focuses on the technique of Wavelet Transformation (WT) to extract the features from an EMG (Electromyogram) signal. It includes decomposing the EMG signal int...

In this paper a system that is designed to extract the musical score from a MIDI performance is described. The proposed system comprises of a number of modules that perform the following tasks: identification of elementary musical objects, calculation of accent (salience) of musical events, beat induction, beat tracking, onset quantisation, streaming, duration quantisation and pitch spelling. T...
