Different phenomena such as complex flow field and heat release by combustion are involved in the heat transfer process in combustion chambers. This paper concerns prediction of heat load and wail temperature in a gas turbine combustor by taking different phenomena into account. Two dimensional axi-symmetric models were used to model the flow field and combustion in a premised combustor with two d
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
In this thesis I have summarised my work on the analysis and improvement of xylose utilisation by recombinant S. cerevisiae. A metabolic flux model was developed and used to analyse the intracellular fluxes in the recombinant xylose utilising S. cerevisiae TMB 3001 cultivated in chemostat at various dilution rates and xylose/glucose concentrations. Xylose uptake increased with xylose concentration
We propose an integrated framework for the design of SOC test solutions, which includes a set of algorithms for early design space exploration as well as extensive optimization for the final solution. The framework deals with test scheduling, test access mechanism design, test sets selection, and test resource placement. Our approach minimizes the test application time and the cost of the test acc
