On Lagrangian meshless methods in free-surface flowsSilverberg, Jon P. 01 1900 (has links)
Classically, fluid dynamics have been dealt with analytically because of the lack of numerical resources (Yeung, 1982). With the development of computational ability, many formulations have been developed which typically use the traditional Navier-Stokes equations along with an Eulerian grid. Today, there exists the possibility of using a moving grid (Lagrangian) along with a meshless discretization. The first issue in meshless fluid dynamics is the equations of motion. There are currently two types of Lagrangian formulations. Spherical Particle Hydrodynamics (SPH) is a method which calculates all equations of motion explicitly. The Moving Particle Semi-implicit (MPS) method uses a mathematical foundation based on SPH. However, instead of calculating all laws of motion explicitly, a fractional time step is performed to calculate pressure. A proposed method, Lagrange Implicit Fraction Step (LIFS), has been created which improves the mathematical formulations on the fluid domain. The LIFS method returns to Continuum mechanics to construct the laws of motion based on decomposing all forces of a volume. It is assumed that all forces on this volume can be linearly superposed to calculate the accelerations of each mass. The LIFS method calculates pressure from a boundary value problem with the inclusion of proper flux boundary conditions. The second issue in meshless Lagrangian dynamics is the calculation of derivatives across a domain. The Monte Carlo Integration (MCI) method uses weighted averages to calculate operators. However, the MCI method can be very inaccurate, and is not suitable for sparse grids. The Radial Basis Function (RBF) method is introduced and studied as a possibility to calculate meshless operators. The RBF method involves a solution of a system of equations to calculate interpolants. Machine expenses are shown to limit the viability of the RBF method for large domains. A new method of calculation has been created called Multi-dimensional Lagrange Interpolating Polynomials (MLIP). While Lagrange Interpolating Polynomials are essentially a one-dimensional interpolation, the use of "dimensional-cuts" and Gaussian quadratures can provide multi-dimensional interpolation. This paper is divided into three sections. The first section specifies the equations of motion. The second section provides the mathematical basis for meshless calculations. The third section evaluates the effectiveness of the meshless calculations and compares two fluiddynamic codes. / Fund number: N62271-97-G-0041. / US Navy (USN) author.

Effektiwiteit van die herwinningsprogrammatuur van leeskompakskyfdatabassise18 March 2015 (has links)
M.A. / CD-ROM products provide access to information by means of different modes of interaction, often on the same database. Although command language is still widely recognized as the interaction mode which retrieves the most relevant references, it is regarded as difficult to use because of its complex structure. More user friendly modes, for example, menu and direct manipulation are viewed as being more accessible to the up-and-coming end-user. The purpose of this study was to determine by means of an empirical study whether the retrieval effectiveness between two modes of interaction on the same database differed significantly. A literature survey pointed out the unique characteristics of existing modes. It was also established that the traditional measures of retrieval effectiveness through relevance and precision could not be applied in this research. A method was devised in which the results of the two modes were compared. The empirical study was done on the command and form fill-in modes of Wilson Business Abstracts. Total results retrieved through each mode were compared, as well as the ease of entering the search by means of appropriate search facilities for each mode. The results of the research revealed that the presence of unique search facilities in a mode results in better retrieval effectiveness. Searches in both modes also require specific ways of input for optimum quality retrieval and thus has implications for intensive training in search methods.

Cracked and Broken Media in 20th and 21st Century Music and SoundKelly, Caleb, n/a January 2007 (has links)
From the mid 20th century into the 21st, artists and musicians manipulated,
cracked and broke audio media technologies to produce novel, unique and
indeterminate sounds and performances. Artists such as John Cage, Nam June
Paik, Milian Kn��k, Christian Marclay, Yasunao Tone, Oval and Otomo
Yoshihide pulled apart the technologies of music playback, both the playback
devices � phonographs and CD players � and the recorded media � vinyl records
and Compact Discs. Based in the sound expansion of the 20th century musical
avant garde, this practice connects the interdisciplinary Fluxus movement with
late 20th century sound art and experimental electronic music. Cracked and
broken media techniques play a significant role in 20th century music and sound,
and continue to be productive into the 21st. The primary contribution of this
thesis is to provide a novel and detailed historical account of these practices. In
addition it considers theoretical approaches to this work. After considering
approaches through critiques of recording media, and concepts of noise, this
thesis proposes novel theorisations focusing on materiality and the everyday.
Ultimately it proposes that these practices can be read as precursors to
contemporary new media, as music and sound art cracked open the fixed
structures of �old media� technologies for their own creative purposes.
