The oxy-fuel combined cycle (OCC) is one of several carbon capture and sequestration (CCS) technologies being developed to reduce CO2 emissions from thermal power plants. The OCC consists of a semi-closed topping Bryton cycle, and a traditional bottoming Rankine cycle. The topping cycle operates with a working medium mixture of mainly CO2 and H2O. This CO2-rich working fluid has significantly diff
We present a hybrid ray tracing system, where the work is divided between the CPU cores and the GPU in an integrated chip, and communication occurs via shared memory. Rays are organized in large packets that can be distributed among the two units as needed. Testing visibility between rays and the scene is mostly performed using an optimized kernel on the GPU, but the CPU can help as necessary. The
We analyze the convergence rate of the Dirichlet-Neumann iteration for the fully discretized one dimensional unsteady transmission problem. Specifically, we consider the coupling of two linear heat equations on two identical non overlapping intervals. The Laplacian is discretized using finite differences on one interval and finite elements on the other and the implicit Euler method is used for the
An underwater ERT survey was made along a planned road tunnel for The Stockholm Bypass Project (Förbifart Stockholm). The aim was to assess the ability to identify variations in the depth of the bottom sediments, as well as variations in rock quality and the possible presence of weak zones in the rock. Reference data from a seismic survey and geotechnical drilling was used for evaluation the resul
Empirically, this thesis has focused on nine research and development (R&D) networks set up to promote a professional approach to care and strengthen the collaboration between health care sectors in a Swedish health care setting. The research project was embedded in an action research approach intended to encourage network development by means of a dialogical process. The specific research que
Our paper aims at making two contributions surrounding the broad discussion of subjectivity in Labour Process Theory (LPT). The first contribution is the proposition of a theoretical model to facilitate the understanding of the processes underpinning the construction of shop floor workers´ self-identities based on discursive managerial regulation. Additionally, the findings of the study are used t
Innovation is arguably one of the present-day buzzwords pervading economic, social as well as cultural life. The innovation concept however is highly ambiguous. Nevertheless most (positivistic) innovation studies employ seemingly “clear-cut” notions of innovation circumventing its highly elusive nature. These “clear-cut” innovation concepts are built on pre-conceived ontological assumptions. Inter
Research funding is essential for promoting internationalization of science, technology and innovation. It is a key mechanism to advance international science, technology and innovation (STI) cooperation. This thesis argues that funding is a dominant driver of internationalization of science, technology and innovation but it is viewed as less than an optimal mechanism because of the trade-offs and
Global vegetation models and terrestrial carbon cycle models are widely used for projecting the carbon balance of terrestrial ecosystems. Ensembles of such models show a large spread in carbon balance predictions, ranging from a large uptake to a release of carbon by the terrestrial biosphere, constituting a large uncertainty in the associated feedback to atmospheric CO 2 concentrations under glob
