Popular Abstract in Swedish Istiden har påverkat utbredning och variation hos många växter i Europa, framförallt arter i tempererade områden (dvs. norra Europa). Under den sista istiden (som slutade för mindre än 15 000 år sedan) täcktes stora delar av norra Europa, bl.a. hela Skandinavien och norra England, av ismassor. Bergskedjor som finns i södra Europa, t.ex. Karpaterna, Pyrenéerna och AlpernThe Helianthemum oelandicum complex shows considerable morphological variation across its geographic distribution in Europe and western Asia. By combining four primer pairs and four restriction enzymes I identified nine cpDNA haplotypes with distinct geographical distributions. Two haplotypes were most frequent over most of the range; one in western Europe and one in eastern Europe. Moreover, diff

As farms are getting bigger with more animals, less manual supervision and attention can be given the animals on both group and individual level. In order not to jeopardize animal welfare, automated supervision is in some way already in use. Function and control of ventilation is already in use in modern pig stables, e.g. by the use of sensors for temperature, relative humidity and malfunction con

The aim of this study was to identify and measure time-consuming human modelling tool activities. Five human modelling tool users at Volvo were observed for five days each. The results showed a wide distribution of both indirect and direct working tasks, as well as non-value added tasks such as waiting time. Most of the activities identified appear to be necessary to perform human modelling simula

A Swedish version of WordNet was created and around 300 Swedish adjectives, mainly from the semantic field of strength, were implemented. This paper is a documentation of the implementation. The purpose of the study was to investigate the possibilities of applying WordNet to Swedish and to illuminate general problems with WordNet as well as specific problems in the handling of adjectives. First, a

For efficient firing in sloping grate bark furnaces, it is important to control the ash line position on the grate. The ash line is the border between burning fuel and fuel which is burned out (ash). Here, the problem of detecting the ash line with an image processing system is treated. The presentation of trend curves to the operator is of special interest. The process is slow and trend curves pr

This thesis defends a hedonistic theory of value consisting of two main components. Part 1 offers a theory of pleasure. Pleasures are experiences distinguished by a distinct phenomenological quality. This quality is attitudinal in nature: it is the feeling of liking. The pleasure experience is also an object of this attitude: when feeling pleasure, we like what we feel, and part of how it feels is

Adaptive control is now finding its way into the marketplace after many years of effort. This paper reviews some ideas used to design adaptive control systems. It covers early ideas which primarily attempt to compensate for gain variations and more general methods like gain scheduling, model reference adaptive control, and self-tuning regulators. It is shown that adaptive control laws can be obtai
