An evacuation experiment including 100 individuals was performed inside a tunnel in order to study the effectiveness of different way-finding installations and to collect data on movement speeds and human behaviour. The participants took part in the experiment individually, and no group interactions were studied. The experiment tunnel was 200 m long and an emergency exit was located 180 m into the

Popular Abstract in Swedish Avhandlingen diskuterar Sociologins position i debatten kring artificiell intelligens, d.v.s sådan AI som kan skapa kunskap på egen hand. Det påpekas att sociologin behöver göra en åtskillnad mellan två sätt att skapa AI system: Symbolisk AI (eller Klassisk AI) och Distribuerad AI – DAI. Den sociologiska litteraturen visar en i stort kritisk attityd till symbolisk AI viThis dissertation is concerned with Sociology’s stance in the debate on Strong Artificial Intelligence, i.e. such AI that is able to shape new knowledge without human interference. There is a need for sociologists to realize the difference between two approaches to constructing AI systems: Symbolic AI (or Classic AI) and Distributed AI – DAI. Sociological literature shows a largely critical attitu

We demonstrate that freeing a single-atom thick layer of hexagonal boron nitride (h-BN) from tight chemical bonding to a Ni(111) thin film grown on a W(110) substrate can be achieved by intercalation of Au atoms into the interface. This process has been systematically investigated using angle-resolved photoemission spectroscopy, x-ray photoemission, and absorption techniques. It has been demonstra

Security of supply is widely addressed in the academia. In this paper we conduct a review of methodologies, discuss strengths and weaknesses and identify areas that would benefit from further research and methodology development. A distinction is made between methodologies used to assess general vulnerability and those that value the outcome of insecurity by testing how energy systems respond to d

Popular Abstract in Swedish Under 1900-talets inledande decennier genomfördes fältarbeten på den svenska landsbygden då äldre bebyggelse och byar dokumenterades på bild och i ord. Dessa dokumentationer ingick i ett större sammanhang, där ambitionen var att alla aspekter av en förmodat försvinnande allmogekultur skulle kartläggas, samlas in och arkiveras. By- och bebyggelsedokumentationerna utfördeIn the first decades of the twentieth century there were fieldwork expeditions in rural Sweden, documenting archaic buildings and villages in words and pictures. These documentation efforts were part of a larger context, where the ambition was to survey and collect all aspects of what was presumed to be a vanishing peasant culture. The documentation was carried out by several different museums and

We have studied theoretically the influence of symmetry breaking mechanisms: structural inversion asymmetry, bulk inversion asymmetry, relativistic and non-relativistic interface Hamiltonian and warping on spin split of levels Delta E and optical absorption of linearly polarized light in asymmetrical quantum wells made from zincblende materials grown on [001] direction. The AlSb/InAs/GaSb/AlSb bro

This paper suggests an extension of an existing, clinically evaluated, closed-loop drug delivery system for hypnotic depth control using propofol. The extension introduces closed-loop administration of the analgesic drug remifentanil, thus forming a multiple input–single output (MISO) control system. Remifentanil acts and is metabolized at a significantly faster time scale than propofol. Direct co

Is contemporary media ecology an ecology that offers unprecedented freedom for producing participators, the "prod-users," or could it also be understood as an ecology in which various forms of user participation are in fact conditioned, or manufactured, by professional producers? Considering the increasing research attention paid to various notions of user participation, these questions become imp

This thesis studies approximate optimal control of nonlinear systems. Particular attention is given to global solutions and to the computation of approximately optimal feedback controllers. The solution to an optimal control problem is characterized by the optimal value function. For a large class of problems the optimal value function must satisfy a Hamilton-Jacobi-Bellman type equation. Two comm

Compared to terrestrial environments, grazing intensity on belowground plant parts may be particularly strong in aquatic environments, which may have great effects on plant-community structure. We observed that the submerged macrophyte, Potamogeton pectinatus, which mainly reproduces with tubers, often grows at intermediate water depth and that P. perfoliatus, which mainly reproduces with rhizomes

Malignant brain tumor is a highly invasive and vascularized cancer. Current forms of therapy are not curative and can, at best, prolong survival for patients with this disease. The mean survival is only around 15 months. The aims of the present thesis have been to develop and explore a stem cell based vector system for delivery of therapeutic transgenes to experimental gliomas. First, we investiga

Newborn male infants have higher morbidity and mortality than female infants. Male fetal gender is associated with an overall increased risk of preterm birth and complications related to pregnancy are overrepresented in women carrying male fetuses. Several studies have shown that being newborn and of male gender are independent risk factors for adverse outcome. Even though experimental data from n

A novel algorithm for detection of saccades and postsaccadic oscillations in the presence of smooth pursuit movements is proposed. The method combines saccade detection in the acceleration domain with specialized on- and offset criteria for saccades and postsaccadic oscillations. The performance of the algorithm is evaluated by comparing the detection results to those of an existing velocity-based

Popular Abstract in Swedish Diabetes mellitus är en folksjukdom som blir allt vanligare, sannolikt till stor del på grund av vår moderna livsstil. Individer med diabetes löper större risk att utveckla många olika komplikationer, bland annat i ögonen, njurarna, blodkärlen och magtarmkanalen. Många diabetiker drabbas av förlångsammad tömning av magsäcken, vilket även kallas gastropares. Gastropares Gastrointestinal dysmotility is common, particularly in patients with diabetes mellitus. The aim of this thesis is to explore whether gastrointestinal dysmotility and endocrine secretion are interrelated, and how the symptoms manifest themselves in these patients. Patients with diabetes mellitus and gastrointestinal symptoms underwent gastric emptying scintigraphy, esophageal manometry and deep-

This article studies partner selection according to three dimensions: social origin, age, and place of birth. The authors use micro-level data from local population registers in five parishes in southern Sweden from 1815 to 1895.The results confirm that all three aspects were important but that socioeconomic status was the most important characteristic,structuring much of the selection process.The

Interest in cross-national partnership is increasing in Europe, a situation very much reflected in calls for funding. Multi-language qualitative research methodologies need to be strengthened in order to support this growing trend toward the promotion of cross-national collaboration. This practice analysis reports on our experience of carrying out cross-national and multi-language based qualitativ

We assessed potential toxicity of fungicides to natural bacterial communities from a constructed wetland, located in southern Sweden, and compared the sensitivity of two endpoints indicating bacterial activity, leucine incorporation, and potential denitrification, in detecting toxicity. The effects of eight fungicides (benomyl, carbendazim, carboxin, captan, cycloheximide, fenpropimorph, propicona
