The problem of recovering scene structure and camera motion from images has a number of inherent ambiguities. In this paper, configurations of points and cameras are analyzed for which the image points alone are insufficient to recover the scene geometry uniquely. Such configurations are said to be critical. For two views, it is well-known that a configuration is critical only if the two camera ce

The present study describes the anthropometrics of the Swedish workforce, aged 18-65, and compares the measurements with data collected four decades earlier. This anthropometric information is based on measurements of a total of 367 subjects, 105 males and 262 females. Of the 367 subjects, 268 responded to advertisements (Study A) and 99 were randomly selected from a community register (Study B).

The formation mechanism of the barium stars is thought to be well understood. Barium-rich material, lost in a stellar wind from a thermally-pulsing asymptotic-giant branch star in a binary system, is accreted by its companion main-sequence star. Now, many millions of years later, the primary is an unseen white dwarf and the secondary has itself evolved into a giant which displays absorption lines

Abstract Preeclampsia is a serious pregnancy complication that affects 3-8% of all pregnancies leading to maternal- and fetal morbidity and mortality. The etiology is still not known in detail. Previous findings have shown an up regulation of the genes coding for fetal hemoglobin (HbF) in preeclamptic placentas. The cell-free HbF protein was shown to be accumulating in the vascular lumen, to induc

This working paper on Tongan names for plants and animals is intended as a contribution to the documentation of environmental knowledge in one of the most traditional societies of Polynesia. The list contains over 1 400 folk taxa: seaweeds 18 names, terrestrial plants 801 names, marine invertebrates 203 names, terrestrial invertebrates 72 names, fishes 231 names, reptiles and amphibians 15 names,

Many engineers and scientists prevalently use computational tools in electromagnetics, which is also the predominant case for antennas. The ever-increasing number of applications and technologies that employ antennas create a constant demand to improve and extend existing tools and develop new ones. This dissertation investigates computational tools for antenna analysis and design. Antenna current

Background: Clinical egg allergy is a common food allergy. Current management relies upon strict allergen avoidance. Oral immunotherapy might be an optional treatment, through desensitization to egg allergen. Objectives: To determine the efficacy and safety of oral and sublingual immunotherapy in children and adults with immunoglobulin E (IgE)-mediated egg allergy as compared to a placebo treatmen

We report the results of a symposium aimed at identifying validated biomarkers that can be used to complement clinical observations for diagnosis and prognosis of joint injury leading to equine osteoarthritis (OA). Biomarkers might also predict pre-fracture change that could lead to catastrophic bone failure in equine athletes. The workshop was attended by leading scientists in the fields of equin

Cities are increasingly facing major transportation challenges, and new sustainable solutions are needed. New ICT-enabled services can be part of solving the problems, including both improving and finding new transportation services and providing digital access to different services. It is important to identify which services have the best potential for environmental benefits (e.g., travel reducti

Sugars and starches belong to the category of carbohydrates, which are important energy sources for organisms and nonessential nutrients in the human diet. Sugars are mono- or disaccharides that can be immediately transformed to energy by organisms. Starches, on the other hand, are polysaccharides, a space-efficient storage of energy for organisms. Before transforming polysaccharides into energy f

During two consecutive years 607 individuals with lower limb fractures were diagnosed. Half of the individuals, 315, were women and only 14 of them had an earlier registration for alcoholism. In the 292 men, however, 73 men or 25%, had been registered at the Department of Alcohol Diseases at least once during the 13 years of observation, the highest registration frequency (30%) was noted in the ma
