Resistivity imaging in combination with drill hole information is a powerful tool in geotechnical site investigations. Traditionally the resistivity data is inverted with a 2D smooth inversion algorithm, resulting in a minimum structure model. In the geological interpretation it can be difficult to determine sharp layer boundaries in these models. An additional parameterized inversion of resistivi

Rapporten redovisar en utvärdering av SI-verksamheten (SI = Samverkansinlärning) vid nio civilingenjörsprogram vid Lunds Tekniska Högskola under läsåret 2009/10 tillämpat på kurser i endimensionell analys, linjär algebra, mekanik samt inledande kemi. Både kursresultat samt poängproduktion under det första året är signifikant bättre för SI-deltagare än de som ej följt SI. Resultaten avseende andel

Popular Abstract in Swedish Cellulosa etrar är en grupp ämnen som har många tillämpningar inom olika områden. Det stora antalet tillämpningar ställer höga krav på de teknologiska egenskaperna hos cellulosa etrarna. För att kunna kontrollera de teknologiska egenskaperna är det nödvändigt att utveckla analytiska metoder, med vilka egenskaperna kan korreleras till den kemiska strukturen. Ibland går dCellulose based derivatives, such as cellulose ethers, today find many applications in a diverse range of fields. The numerous applications put high demands on the technological performance of the cellulose ethers. In order to be able to control the technological properties it is necessary to develop analytical methods by, which they can be correlated to the chemical structure. In some cases va

This thesis describes the affinity and enantiomeric selectivity of the cellobiohydrolase Cel7A (isolated from Hypocrea jercorina). The chiral recognition of the enzyme has been studied with respect to amino alcohols and new ligands have been designed, based on the structure of the common ?-blocker propranolol. Capillary electrophoresis have been used to determine the dissociation constants of the

With today’s rapid changes in socio-economy and technology, knowledge and learning are critical issues for most companies and private and civil service organisations. The needs for competence development range from short informal courses to formal educational programs at university level. Informal learning is less predictable. It is nevertheless a very natural way of learning, although it is often

This paper investigates the dimensioning of a server used for external overload control in service architecture. Great savings can be obtained by an operator if the dimensioning analysis is performed correctly. As one of the main parts of this paper it is shown that Poissonian arrivals is a good assumption for some services in service architectures. Methods that can be used for dimensioning are pr

The consolidation of paper during drying is of interest to increase the understanding of the development of the paper quality. The mercury displacement technique proved suitable to measure the apparent solid density and the volume fractions of solid, liquid and gas in wet paper sheets. Measurements were performed on handsheets of chemi-thermomechanical pulp (CTMP), bleached and unbleached softwood
