Abstract:

<p>To control the exhaust gas recirculation (EGR) and the exhaust brake, the position of a butterfly valve connected to a piston inside a pneumatic cylinder is controlled by altering the pressure inside the cylinder. This thesis evaluates the possibility to do this with pulse width modulation (PWM) controlled On/Off valves. The whole electro-pneumatic actuator system is built out of two On/Off valves and a cylinder.</p><p>A mathematical model of the system is constructed. The complete system model on state space form consists of nine states and is nonlinear. The model captures the dynamics of

Abstract:

Most commercially available valves are able to produce a large flow rate or a fast response, but are incapable of producing both simultaneously. Commercially available valves that can achieve both are expensive as they require multiple stages of actuation and piloting pressures to deliver large flow rates quickly, preventing them from being broadly used in fluid power applications. This work investigates the design of an Energy Coupling Actuated Valve (ECAV) that is capable of solving this trade-off between large flow and fast switching times through the use of an innovative, high performance

The ability to control engine valve timing has the potential to alter the engine performance over the entire operating range. The outcome of valve timing technology enables the possibility to increase efficiency, lowering emissions, increase engine torque, etc. One of the simplest ways to obtain a variable valve timing is to use cam phasers. The dynamics of a hydraulic cam phaser has been studied, three concepts with the purpose to control such an element has been developed using simulation driven product development.

The elimination of resistance flow, and the recuperation of energy makes it very efficient alternative. The difficulties of IEHEC machine to step to the market has been the requirement of one IEHEC machine per one actuator.

This means that carriers are forced to perform these deliveries during the day, which leads to inefficient distribution.

This paper examines the underlying drivers of MLB franchise value. Using panel data for MLB teams from 2000-2010, I find that a team’s ballpark and metro-area market are significant determinants, yet revenues truly drive value. Further, I find that incremental increases in winning percentage by a particular team has an insignificant effect on total revenues and has no marginal impact on the value of the team, particularly if the team recognizes consistent revenue streams every year. Finally, I show that the modern sabermetric approach to player management negatively impacts firm value, sugge

Abstract One of the major features of financial reporting is conservatism. Accounting conservatism is traditionally defined by the adage “anticipate no profit, but anticipate all losses.” Accounting conservatism is manifested in two general but distinct ways. First, conservatism can be unconditional, meaning that the book value of net assets is understated due to predetermined accounting practices (e.g. immediate expensing of research and development expenditures as incurred). Second, conservatism can be conditional, meaning that the book value of assets is written down under sufficiently adve

The causes of allograft valve degeneration are still unknown. The study aims to identify factors associated with cryopreserved allograft valve degeneration.

In contrast to the focus on growth and investment, relatively little attention has been paid to understanding the extent to which off-road cycling benefits the tourism and leisure economy. Fur

With a flat slide valve concept, when compared to conventional piston spool valves, reduced leakage and increased service life could be achieved. In order to achieve a reduction of leakage flows and guarantee the adjustability of the valves at the same time, a correct design of the pressure compensation is essential. The magnitude of force depends on both the operating point of the valve and the position of the slider. Due to the design of the flat slide valve, it is possible to use ceramic semi-finished products for the main stage, which consist of control plates and a slide plate. The geomet

Abstract:

One of the main aims of the underlying research is to respond to continuous calls for introducing and measuring a sound economic definition for best practice disclosure quality (e.g. Beyer et al., 2010) that is derived from a reliable guidance framework (Botosan, 2004) using an innovative natural language processing technique (Berger, 2011). It also aims to examine the impact of corporate governance on best practice disclosure quality. Finally, it aims to examine the joint effect of both best practice disclosure quality and corporate governance on firm value. The thesis contributes to disclosu

Abstract:

The objective of this study is to evaluate the value drivers that drive the value of companies, as reflected in the share-prices. Through this study, the aim is to draw conclusions on the aspects that drive the share-price of companies. A detailed literature study was performed on the value-creation process that takes place in a company. The literature study has a significant focus on Value-Based Management and the elements that should be considered when evaluating the manner in which companies create shareholder value through the operational activities that are performed. Through applying the

Abstract:

The initial idea for this research is based on the gap that I found in my company performance and specifically in the process of value offering and the relationship with customers.

Abstract:

This thesis starts with the fundamentals of matrix theory and ends with applications of the matrix singular value decomposition (SVD). The background matrix theory coverage includes unitary and Hermitian matrices, and matrix norms and how they relate to matrix SVD. The matrix condition number is discussed in relationship to the solution of linear equations. Some inequalities based on the trace of a matrix, polar matrix decomposition, unitaries and partial isometies are discussed. Among the SVD applications discussed are the method of least squares and image compression. Expansion of a matrix a

Abstract:

The production of steroid and drug metabolites is a key area within the pharmaceutical industry. For a drug to pass safety profiling, large amounts of its metabolites are required to undergo extensive toxicology studies. Steroid compounds can be used in the treatment of chronic inflammatory disorders and also demonstrate efficacy in reducing cancerous tumour mass. A key step in the synthesis of these compounds is the insertion of an oxygen atom into a specific C-H unactivated bond. Cytochrome P450 (P450s) circumvent the limitations of synthetic methods for production of high value oxychemicals

Abstract:

Thesis (MA)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: The value of art is a critical concept in theoretical discourse. As a result, the high prices of artworks on auctions pose questions about the various processes of value construction and the status of art in these processes. This thesis adopts a sociological approach to the construction of value of art on South African auctions. This approach is situated within a socio-historical perspective, which introduces the various social structures and conditions of cultural production. The main premise of this approach is that a mul
