The Modified Smoothed Particle Hydrodynamics (MSPH) method proposed earlier by the authors and applied to the analysis of transient two-dimensional (2-D) heat conduction, 1-D transient simple shearing deformations of a thermoviscoplastic material, 1-D wave propagation in a functionally graded plate, and 2-D elastodynamic crack propagation is extended to the analysis of axisymmetric deformations...

This paper describes the proposed algorithm submitted to the MIREX 2009 “Audio Melody Extraction” task. The algorithm addresses the task of extracting the predominant melody pitch from a polyphonic audio signal. The algorithm extracts the melody pitch in three steps. In the first step, transient analysis is performed on the polyphonic audio signal to determine the analysis frame length, and the...

The transmission line method (TLM) is a very efficient method for dynamic modelling of flow in pipelines, and uses delay elements to represent wave propagation. In this paper an existing TLM model is investigated and shown to have some deficiencies. Some adjustments are proposed to avoid these deficiencies and enhance the transient and steady state accuracy. Very good agreement is obtained betw...

This paper deals with a lumped-parameter dynamic simulation of a single-effect LiBr-H2O absorption chiller. In many studies the thermodynamic properties of LiBr-H2O solution were taken from some approximate relations causing the results to be somewhat inaccurate. These relations were used to solve simultaneous differential equations involving the continuity of species constituting the LiBr-H2O ...

In this paper, the consequences of filled volume on the transient lateral dynamic and stabilities boundaries displacement of an articulated vehicle carrying liquid is investigated. First, a sixteen-degrees-of-freedom nonlinear dynamic model of an articulated vehicle is developed then, using TruckSim software the model is validated. Next, the dynamic interaction of the fluid cargo with the vehic...

High-performance database systems have to support ad-hoc queries while providing high transaction throughput. Transient versioning methods, where prior versions are maintained temporarily, are developed to execute queries without aaecting concurrent transactions. However , transactions in these methods do not exploit the prior versions. This paper presents a transient-versioning method, called ...
