A numerical investigation has been carried Out for the turbulent fluid flow and heat transfer in periodic fully developed corrugated ducts. Three turbulence models are used in the calculation: the standard k - epsilon model, the Re-Normalized Group (RNG) k - epsilon model and a Reynolds Stress Model (RSM). The turbulent heat flux is modeled by the simple eddy diffusivity model (SED). The numerical
Although the research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support have not emerged so far. Therefore, the creation of such systems remains a difficult, time-consuming and error-prone process. The absence of principled support for system evaluation and optimization at high level of abstraction makes the quality of the
This essay reflects on issues surrounding the remembrance and teaching of the Holocaust. It was commissioned by the project Living History and the Swedish Prime Minister's Office.

Popular Abstract in Swedish Patienternas perspektiv på att vara IVA patient i relation till IVA syndrom/delirium Att intensivvårdspatienter (IVA patienter) som vårdats med respirator inte minns sin tid på IVA är en myt. Det finns patienter som inte minns , men de flesta patienterna i avhandlingen minns från uppvaknandet och borttagandet av droger och respiratorn sin tid de närmaste dagarna däreftWhen a person becomes critically ill, injured and/or undergoes major surgery and requires intensive care, a complex dilemma can arise. The condition of the illness, the specific caring situation and the environment lead to significant changes and effects in the senses and perceptional abilities. Under these conditions some patients can develop symptoms of the Intensive Care Unit syndrome/delirium.
Popular Abstract in Swedish Den fria volymen i en polymer är kopplad till flera fundamentala fysikaliska egenskaper som till exempel densitet, viskositet och gas diffusivitet. De fysikaliska egenskaperna hos polymerer i närheten av, eller i kontakt med, en solid yta har visats vara väsentligt olika dess bulkegenskaper. De fysikaliska egenskaperna hos polymerer i närheten av, eller i kontakt med, yThe free volume in polymers is coupled to several important physical properties, such as density, viscosity and gas diffusivity. The physical properties of polymers close to a solid surface have been shown to be significantly perturbed as compared to their bulk state. The behavior of polymers close to surfaces comes into play within the field of polymer composites, where the properties of the inte
This paper aims to present and suggest, from a foreigner's angle, ways in which to better explain and understand the difficulties facing Chinese policy-makers and government agencies that seek to improve the sustainability of China's industrial development. In this context, improved energy efficiency in the industrial sector is crucial; constituting a central pillar for all such strategies. The pa
The paper reports a project conducted within the framework of the National Library of Sweden's Expert Group on Library Statistics. The project is financed by the National Library of Sweden, and it aims to capture how library managements make use of the current library statistics (based on the ISO-standard) in the decision-making process. Questions are also asked about the quality and usefulness of
The swift acceptance and the widespread use of virtual environments has substantially increased the stress on networks as each of the operating systems running in parallel sends out packets over the same network. As an increased number of packets traverse a network, the importance to continuously monitor whether the network is providing satisfactory service has increased. The metrics for such anal
Popular Abstract in Swedish Ett membrans främsta funktioner är dels att fungera som en barriär och dels reglera transport mellan membranets omgivningar. I biologiska membran så utgörs barriären till stor del av lipider. Lipider är amfifila molekyler som består av en polär del som trivs i vattenrika miljöer, och opolär del som skyr vatten. I membranet så ordnar sig lipiderna i bilager. Ett bilager This thesis concerns the interplay between the lipid phase behaviour, domain formation and the permeability of bilayer membranes. An essential part of this work has been the understanding of the phase transitions and equilibrium properties of lipid bilayers. In this approach experimental results of lipid phase behaviour have been correlated to theoretical descriptions of the systems. An isothermal
Popular Abstract in Swedish Fåglars spektakulära flyttningresor fram och tillbaka över jordklotet har länge fascinerat forskarna, men många frågor kring fåglarnas flyttningsbeteende är ännu obesvarade. Vadare är en av de fågelgrupper som flyttar allra längst, ofta från nordliga häckningsområden uppe på den arktiska tundran till övervintringsområden på södra halvklotet. I avhandlingen används moderThe migratory behaviour of birds has received much scientific interest, though many questions still remain unsolved. One of the reasons for this is the difficulty of following the birds as they move between breeding and wintering localities. Populations may mix on migration and the origin of individual birds is difficult to assess. One way to address this problem may be to develop genetic populati
Popular Abstract in Swedish Det här arbetet handlar om individuell religiositet, snarare än om religion. Min studie rör i första hand människor som utövar zen, och har mindre att göra med zenbuddhism som ideologiskt system. Jag försöker utforska det stora gapet mellan teori och praktik. De mer abstrakta doktrinerna och idealiserande normerna har haft en benägenhet att dominera arbeten om zen, såväThis work is not so much about religion as about individual religiosity. It is primarily about people practicing Zen, less about Zen Buddhism as a systematic ideology or philosophy. I set out from the start to try to explore the wide gap between theory and practice in Zen. The more abstract doctrines and idealized norms have had a tendency to dominate works on Zen, confessional as well as scholast
