An affine invariant deformable shape representation for general curves

Automatic construction of Shape Models from examples has been the focus of intense research during the last couple of years. These methods have proved to be useful for shape segmentation, tracking and shape understanding. In this paper novel theory to automate shape modelling is described. The theory is intrinsically defined for curves although curves are infinite dimensional objects. The theory i

Remote monitoring and logging of relative humidity in concrete

It is important to measure the relative humidity, RH, level in a concrete slab before applying semi permeable flooring to the surface. If the moisture level in the concrete is too high when the flooring is applied the high alkali level in combination with the moisture will degrade the adhesive. This paper describes a new system used to continuously measure and monitor RH in situ during the constru

Ovarian cancer and oral contraceptives: collaborative reanalysis of data from 45 epidemiological studies including 23 257 women with ovarian cancer and 87 303 controls

Background Oral contraceptives were introduced almost 50 years ago, and over 100 million women currently use them. Oral contraceptives can reduce the risk of ovarian cancer, but the eventual public-health effects of this reduction will depend on how long the protection lasts after use ceases. We aimed to assess these effects. Methods Individual data for 23 257 women with ovarian cancer (cases) a

Proposal and evaluation for organising and using available data for software performance estimations in embedded platform development

Embedded platform development, where a platform is a basis for a family of products, is characterized by soft-and hardware co-design as well as very tight constraints on cost and available real-time system performance. The latter implies that early software performance estimation plays a crucial role in embedded platform development. Due to the different focus of software and hardware design, perf

Etniskt företagande som startmotor: Erfarenheter från somaliska företagare i USA

Det är tio gånger så vanligt att migranter från Somalia startar eget företag i Minnesota, som i Sverige. Sysselsättningsgraden för somaliafödda är också två till tre gånger högre i USA. I rapporten ”Etniskt företagande som startmotor” har ekonomhistorikerna Benny Carlson och Tobias Schölin vid Lunds universitet intervjuat företagare och företrädare för somaliska företagarcenter i Minnesota.

Proper functioning of domestic hot water circulation in residential buildings

The paper deals with domestic hot water circulation (DHWC) in residential buildings. Thermostatic circulation valves (TCV) of self-acting type can be used to assure proper temperature level in DHWC systems. A mathematic model of a DHWC system with TCV's in a 36 flat residential building is presented as well as results from steady-state and dynamic Simulations. The TCV design values used in simulat

Uncertain Futures : Adaptive capacities to climate variability and change in the Lake Victoria Basin

The Lake Victoria basin (LVB) in East Africa can be considered a climate change hotspot because of its large rural population dependent on rain-fed farming. Drawing on extensive fieldwork (2007-2011) in rural communities along the shores of Lake Victoria in Kenya and Tanzania, I explore adaptive capacities to climate variability and change and discuss how they interrelate in situ. Using multiple m

The corticolous and lignicolous species of Bacidia and Bacidina in North America

This is a taxonomic revision of the corticolous and lignicolous taxa of the genera Bacidia and Bacidina (Lecanoraceae, Lecanorales, lichenized Ascomycotina) in the continental United States and Canada. Twenty-seven species of Bacidia (one of which is divided into two subspecies) and twelve species of Bacidina are recognized. The morphology, secondary chemistry, ecology, and phytogeography of these

Pedagogical courses as a way to support communities of practice focusing on teaching and learning

This paper argues for the idea that pedagogical courses for university teachers should be designed with a socio cultural perspective on learning in mind. It also presents an example of such a design. Teaching and learning regimes are ways to understand crucial aspects of teaching within e.g. departments. They are constructed within communities of practice where colleagues use whatever resources t
