The evaporative gas turbine pilot plant (EvGT) has been in operation at Lund Institute of Technology in Sweden since 1997. This article presents the latest development in the evaporative technology, the evaporation of bio-ethanol in a gas turbine power plant as a means to reduce the emission of greenhouse gases. Bio-ethanol is produced from a feedstock consisting of corn-stover, and the bio-ethano

Popular Abstract in Swedish Färsk morotsjuice har ett högre förädlingsvärde än råa morötter. Färsk morotsjuice har en kort hållbarhet på cirka tre dagar vilket försvårar centraliserad industriell storproduktion. Olika processteg vid tillverkningen av morotsjuice påverkar såväl hållbarhet som näringsinnehåll och utseende. Syftet med detta arbete var att undersöka och karakterisera effekter av olikaCarrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. The fresh carrot juice produced today has a short shelf-life of approximately three days, which makes centralised industrial production and distribution difficult, an

We explain autonomy with full-fledged reference to the complementaristic conception of language and its introspective capabilities. This field that we refer to is understood to belong to a wider epistemic category than that of (the received view of) semiotics as well as of systems science. It follows from the linguistic complementarity that autonomies (self-references; independencies) can never be

This thesis concerns the application of artificial neural network techniques to space weather physics. The networks applied include multi-layer error-backpropagation, radial basis function, and self-organized maps. Different parts in the solar-terrestrial chain are analysed with the emphasis on developing methods for real time predictions of geomagnetic activity. The neural networks are general mo

Several approaches towards the optimization of amperometric biosensors using a soluble mediator in combination with reticulated vitreous carbon (RVC) were studied. RVC material was used as the working electrode with biomolecules (enzyme/co-enzyme) immobilised on its surface and intergrated with a FIA system. By using the soluble electron transfer mediator Meldola Blue the oxidation potentials for

Protein structure and stability are inherent in the amino acid sequence and governed by non-covalent interactions. The cooperation between forces is, however, perplexing and not well understood. In order to elucidate and predict protein folding and stability, detailed studies of non-covalent interactions are required. Presented in this thesis are detailed studies on electrostatic interactions in

Anomaly detection is becoming a powerful and necessary component as wireless networks gain popularity. In this paper, we evaluate the efficacy of PCA based anomaly detection for wireless mesh networks (WMN). PCA based method [1] was originally developed for wired networks. Our experiments show that it is possible to detect different types of anomalies, such as Denial-of-service (DoS) attack, port

Human papillomavirus (HPV) type 16 is the major cause of cervical intraepithelial neoplasia and anogenital cancers. The antibody response to papillomaviruses is a key determinant of protective immunity and forms the basis for prophylactic vaccine development as well as for seroepidemiology. The present thesis has evaluated different methods for HPV antibody measurements, determinants of the HPV an

In every gathered group of people, one person will be appointed the leadership. The choice of leader will be mutual and based on that this person has the most appropriate and trained talent for leadership and is best prepared for the task. Ultimately there should be a team of leaders that support each other and co operate in the leadership, or take turns. Leadership is dependent on the human facto

Popular Abstract in Swedish Bortglömda, stulna eller på andra sätt borttappade radioaktiva strålkällor som kan anses vara farliga för allmänheten kallas herrelösa strålkällor. Denna avhandling handlar om metoder för att hitta herrelösa strålkällor som emitterar s.k. gammastrålning, bestående av ljuspartiklar med mycket hög energi. Gammastrålning har god förmåga att penetrera materia och kan därförHazardous radioactive sources out of regulatory control are referred to as orphan sources. Focussing on gamma-emitting orphan sources, this thesis describes methods that can be used in mobile gamma-ray spectrometry to perform real-time discrimination between an actual source signal and the signal due to the natural radiation background. Two categories of methods for orphan source detection are pre

When simulating small probabilities, say of order 10-6 or less, by importance sampling, an established principle is to choose the importance sampling distribution as close to the conditional distribution given the rare event as possible. Implementing this often leads into large deviations calculations and exponential change of measure. We survey some of the standard examples where this approach wo
