In this paper we suggest an improvement to a recent algorithm for estimating the pose and ego-motion of a camera which is constrained to planar motion at a constant height above the floor, with a constant tilt. Such motion is common in robotics applications where a camera is mounted onto a mobile platform and directed towards the floor. Due to the planar nature of the scene, images taken with such
Energy efficiency scenarios are developed in the national and international context to explore and evaluate different policy designs and visions of how energy will be generated, distributed and used in the future. However, these scenarios are often developed using conventional bottom-up modelling tools that, to only a limited extent, take into account decentralised decision-making frameworks, such
Societal safety and sustainability are key challenges in our complex and dynamic world, causing growth in interest of applying the concept of resilience in broader societal contexts. This paper presents a concept of Community Resilience that builds on established theory of Resilience Engineering and operationalises the concept by presenting its purpose, required functions and a way to identify and
Popular Abstract in Swedish Hur är det möjligt att planera om en kommun från arbetarstad till kunskapsstad? Idag har en rad svenska och europeiska kommunledningar ambitionen att återuppfinna städer genom att tvätta bort industristaden och ersätta den med en kunskaps-, informations-, kultur-, och/eller evenemangstad. Den här formen av kommunal utvecklingsplanering har genererat en rad olika frågor What are the discursive pre-conditions for planning? In this dissertation the author analyzes and critically assesses the assumptions which underlie our thinking about planning. This is done in an analysis of firstly, how planning is legitimized, and secondly, what consequences these forms of legitimation have for planning theory as well as for planning as a political practice. The author descri
Popular Abstract in Swedish En studie av hur glokokortikoider hämmar inflammation Glukokortikosteroider, varav kortison är den mest kända, är hormoner som reglerar många funktioner i kroppen och även används som läkemedel för att dämpa inflammatoriska tillstånd som t.ex. astma och reumatiska sjukdomar. Glukokortikosteroider är mycket potenta läkemedel och används flitigt med mycket goda effekter.The aim of this investigation has been to study mechanisms by which glucocorticoids inhibit inflammatory processes in vitro. Type IV cytosolic 85 kDa phospholipase A2 (cPLA2) is an important modulator of inflammatory responses that is present in macrophages as well as in other cell types. In macrophages, the synthetic glucocorticoid dexamethasone (dex) was found to reduce the expression of cPLA2 a
Syftet med denna undersökning var att bestämma en 1 kg isvästs kylverkan på kroppen vid brandmansarbete. Testerna genomfördes i en klimatkammare, i en container med extrem strålningsvärme och i ett rökdykningshus med värme och tungt arbete. Den faktiska kylverkan mättes också med en termisk docka. Fyra erfarna brandmän deltog i försöken. I alla tester bar försökspersonerna standardklädsel för branThe aim of the present study was to examine the effects of wearing a light-weight ice-vest (1kg, water) on physiological and subjective responses in fire fighter’s work. The experiments were carried out in a climatic chamber, in a container under extreme radiant heat, and during simulated smoke-diving. In addition, the physical cooling effect of the ice-vest was measured with a thermal mannequin.
Defining, prioritizing, and selecting requirements are problems of tremendous importance. In this paper, a new approach called Quantitative WinWin for decision support in requirements negotiation is studied. The difference to Boehm's WinWin groupware-based negotiation support is the inclusion of quantitative methods as a backbone for better and more objective decisions. Like Boehm's original WinWi
We describe a very efficient method for fluorescent labeling of acidic structures in denervated skeletal muscle with rhodamine B. Rhodamine B at 50 ng/ml gave selective and distinct segmental labeling of denervated muscle fibers after 5-min incubation at room temperature. Labeling was also achieved at 4 degrees C. The labeling was disrupted by the ionophores monensin and nigericin, suggesting a la
Ion beam irradiation of silicon followed by electrochemical etching has been used to produce fluid anchor points on a sample target plate for matrix assisted laser desorption ionization mass spectrometry. Non-porous areas on the fabricated target plate serve as anchor points for sample deposition. High hydrophobicity of the macroporous silicon surface surrounding anchor points intrinsically led to
Objective: To evaluate risk factors - notably drugs - for developing acute pancreatitis. Methods: A population-based, case-control study, encompassing 1.4 million inhabitants aged 20-85 years from four regions in Sweden between 1 January 1995 and 31 May 1998. A total of 462 cases were hospitalised in surgical departments with their first episode of acute pancreatitis without previously known bilia
BACKGROUND: Proper treatment of lymph node-negative breast cancer depends on an accurate prognosis. To improve prognostic models for this disease, we evaluated whether an immunohistochemical marker for proliferating cells, Ki-S2 (a monoclonal antibody that binds to a 100-kd nuclear protein expressed in S, G2, and M phases of the cell cycle), is an accurate indicator of prognosis.METHODS: We studie
A new chamber has been designed and constructed for the second beam line at the Lund Nuclear Microprobe facility, Sweden. The aim with the chamber is to perform standardized analyses with most of the nuclear analytical techniques (proton induced X-ray emission, particle elastic scattering analysis, proton induced gamma emission, nuclear reaction analysis, etc.) with a millimetre size beam. The bea
The fundamental equations for the theoretical treatment of wood during the process of pyrolysis are presented in Chapter 1. Expressions which must be specially introduced for combustible materials are those which describe the pyrolyctic reaction and reactions at the surface of the material. The reactions are assumed t o conform to first order Arrhenius functions. The treatment also includes the va
