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

Determination of over current protection thresholds for class D audio amplifiers

Monolithic class-D audio amplifiers typically feature built-in over current protection circuitry that shuts down the amplifier in case of a short circuit on the output speaker terminals. To minimize cost, the threshold at which the device shuts down must be set just above the maximum current that can flow in the loudspeaker during normal operation. The current required is determined by the complex

Current issues in pictorial semiotics. Lecture one: The Quadrature of the Hermeneutic Circle.

The first lecture will present pictorial semiotics within the framework of general semiotic theory. It will construe semiotics as a particular point of view taken on everything which is human or, more generally, endowed with life, rather than simply the continuation of the mixed or separate doctrines due to Saussure and Peirce. The historical part will describe briefly the development of pictorial
