The estimation of structure and motion from image sequences using corresponding points, lines, conics and structured patches is treated. Recent research has provided good tools for obtaining good initial estimates of structure and motion using point, line, conic and curve correspondences. These estimates are, however, not so accurate. It is shown how to obtain statistically optimal estimates of st

In this study we tested the relevance of the generational hypothesis, i.e. whether the era in which household members grew up matters when understanding and predicting their behaviour, on a sample of 600 Swedish households. These households participated in a survey where they answered questions about their own energy-related residential energy behaviour. The answers were analysed for differences b

Popular Abstract in Swedish Cancer i tjock- och ändtarmen är idag den tredje vanligaste formen av till döden ledande cancer i världen. Den är vanligast i de högindustrialise-rade delarna av världen: Europa, Nord-Amerika och Australien. Prognosen för den enskilde patienten är helt beroende på cancerns utbredning vid diagnostillfället. Cancerns utbredning bedöms idag enligt olika indelningsprincipeAim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. The idea was that a rectally applied contrast medium causing distension and signal void of the rectal lumen and an intravenous inj

In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. In addition, the thesis deals with the basic development of large-area double barrier resonant tunneling diodes, as a st

Based on observations of the rhythmic structure of L2-speech produced by L1-speakers of Albanian – which suggest the occurrence of transfer – a study is presented here that compares durational aspects between the two languages. In order to do this, speech read by Swedish and Albanian L1-speakers was recorded and investigated, and normalized durational factors were analysed. The results, however, d

Rapporten behandlar utformning av anslutningen mellan yttervägg och platta på mark samt dess inverkan på fukttillståndet i syllar av främst trämaterial. Undersökningen omfattade dels fältmätningar och dels koretiska beräkningar, dessutom gjordes en del laboratorieförsök. Rekommendationer för utformning.

The ovaries of 377 women between the age of 40 and 70 years were measured by ultrasound. About one third of the patients were postmenopausal. Mean value, standard deviation and S.E.M. of the ovarian volume were calculated and related to age, parity and menstrual cycle. Ovarian size decreased with age in all women but bore no relation to parity and day of menstrual cycle in the menstruating group o

We evaluated the incidence and clinical significance of postfracture shortening of the clavicle in 85 patients. There were 71 mid-clavicular fractures and 14 of the lateral end of the clavicle. 46 fractures were primarily undisplaced and 39 displaced. All fractures were nonoperatively treated with sling immobilization. All patients were reexamined 5 years after the fracture. 35 clavicles had heale

Taxa within the Dactylorhiza incarnata/maculata species complex form a diploid and tetraploid complex. The genetic variation revealed by molecular markers indicate that this is a young complex and that polyploidization may be an ongoing process; most, if not all, of the polyploid taxa may have evolved after the last ice age. This conclusion is supported by 1) a close correspondence in general dist

Responses to isotonic quick release of AC-stimulated smooth muscle strips from rabbit urinary bladder were analysed. Releases were performed at the peak of contraction and at a preset tension level in the contraction and relaxation phase. In other expts. responses at 37 degrees C and 27 degrees C were compared. The length response always consisted of 3 parts: (1) elastic recoil, (2) rapid length c

We calculate the cross section for c(c) over bar g -production in diffractive DIS with finite quark masses at zero momentum transfer t. The calculation is done in the leading log(1/x(P)) approximation and is valid in the region of high diffractive masses M (small 3). We apply our cross section formula including both c (c) over bar- and c(c) over bar g in a Monte Carlo simulation to diffractive D*(

Popular Abstract in Swedish Avhandlingen visar två olika vägar för att skapa brukarinflytande, den kollektiv- och den individinriktade vägen. Den kollektiva inriktningen innebär att medborgarna endast kan utöva inflytande via folkvalda företrädare, medan den individinriktade vägen ger möjlighet att samverka direkt med politiker och tjänstemän i den kommunala organisationen. Två olika teorier har aThe dissertation shows two different means or directions for creating civic participation: the collective and the individual way. The collective way is characterized by the citizen's ability to participate only through elected representatives while the individual way makes it possible for inhabitants to participate face to face with politicians and local civil servants. Two different theories hav

BACKGROUND: Self-reported annoyance from electrical equipment has been in evidence since the mid-1980s, and the first reports of illness from everyday chemicals arose in the 1960s. However, the extent of the problem has not yet been fully established.AIMS: The aim of this study was to estimate the prevalence of annoyance related to electrical and chemical factors in a Swedish general population, a
