A Methodology for Operations Planning

The key to successful manufacturing of complicated geometry in numerically controlled machines lies in the control and quality of operations planning. This thesis presents a methodology for automated operations planning for milling with five axes. The goal in this research has been to develop a methodology to achieve complicated machining faster than today. The result is a methodology that uses pl

Production of recombinant PSA and HK2 and analysis of their immunologic cross-reactivity

Measurements of prostate-specific antigen (PSA) in serum are widely used to monitor patients with prostate cancer, but the attenuation of the assay response by PSA complexed to protease inhibitors has been shown to affect the results in certain assay designs. Moreover, the human glandular kallikrein-2 (hK2), a kallikrein-like serine protease that is 80% similar to PSA, might interfere with the spe

Nitritation and denitritation in sludge liquor treatment

Popular Abstract in Swedish Övergödningen av Östersjön är fortfarande ett problem. Förhöjda krav på kvävereduktion för de svenska avloppsreningsverken är därför att vänta. Detta innebär i sig ökad energi- och kemikalieförbrukning, vilket rimmar illa med ord som energieffektivisering och resurssnålhet. Biologisk kväverening av en specifik delström på reningsverket har dock potential att minska ytbeEnhanced biological nitrogen removal at municipal wastewater treatment plants is a common procedure to prevent eutrophication in water bodies. Increased load, stricter effluent regulations, and demands for reduced resource and energy consumption present new challenges for the wastewater treatment plants. One option when upgrading a wastewater treatment plant is to treat the sludge liquor produced

Design as problem handling – outline of a framework

This paper presents an ongoing work concerning the development of a theoretical framework for design. The framework is intended to be applied to the development of information systems for architectural design. The paper combines ontological and epistemological perspectives using Bunge’s work as a starting point, supplemented with Schön’s studies of the general nature of design, and with examples o
