High Speed Combustion Imaging in a Large Bore Gas Engine: The Relationship Between Pre- and Main Chamber Heat Release

An experimental study is carried out to investigate the combustion process in a Wartsila 34SG spark-ignited lean burn four-stroke large bore engine (bore 340 mm) by means of optical diagnostics when operating on natural gas. The main focus of this work is to gain knowledge about in-cylinder combustion phenomena when igniting a lean air/fuel mixture with pre-combustion chamber induced jets. Especia

Modelling and Analysis of Cutting Forces, Traction Loads and Thermoelasticity of Carbide Cutting Tools in Turning Operations - Theory and Experiments

In modern manufacturing the production safety is often the key factor to achieve good product quality. Factors that influence the production safety are many, durability of machining centres, electric power supply and also the tool life. The tool life is governed by the ability to resist wear and failure. The long term wear is usually easy to predict contrary to premature failure. Premature failure

Polyelectrolyte - Surfactant Interactions in Dilute Suspensions. A Study Based on Monte Carlo simulations and Mean-Field Calcultations

The complexation of macroions or charged micelles and oppositely charged polyelectrolytes was studied by the use of Monte-Carlo simulations and mean field calculations. The Monte-Carlo simulations were performed on a simple model system with the emphasis on the electrostatic interaction, (i) polyelectrolyte rigidity, (ii) polyelectrolyte linear charge density, (iii) surfactant tail length, and (iv

Women, Work and Computerization. Opportunities and disadvantages

This book deals with the introduction of new technology into women's work - the impact it is making the problems it generates. The emphasis is placedon the exploraiton of women's perspectives on computerization in the office and in manufacturing. Other topics dealt with include: -an analysis of the strengths and weaknesses in women's participation in systems design and in educaton: - an examinatio

Exploring options for individual producer responsibility for waste from private households for the Waste Electrical and Electronic Equipment Directive

The Waste Electrical and Electronic Equipment (WEEE) Directive of the European Commission places the responsibility on producers to finance collection and treatment of waste deposited at collection facilities after 13 August 2005, on a collective or individual basis. The research identifies practical steps that are needed for producers to address WEEE from private households on an individual, rath

At the turn of the Century the man/woman-relationship was debated in media, public leisure life and in the genre of self help literature. The “Heterosexual Couple” was – and is - portrayed in a number of culturally fixed and thematic ways, often conceptualized via the dichotomies of Male and Female, harmony and conflict, the traditional and the modern, ideal and reality. In this thesis different

Transient electromagnetic wave propagation in anisotropic dispersive media

Transient electromagnetic wave propagation in a stratified, anisotropic, dispersive medium is considered. Specifically, the direct scattering problem is addressed. The dispersive, anisotropic medium is modeled by constitutive relations (a 3 3 matrix-valued susceptibility operator) containing time convolution integrals. In the general case, nine different susceptibility kernels characterize the med
