Large Eddy Simulation of Turbulent Reactive Flows under HCCI Engine Conditions

Popular Abstract in English In the past ten years, homogeneous charge compression ignition (HCCI) combustion has been one of the subjects receiving great research interests in the combustion research community and the engine industry. This is because HCCI combustion processes have the potential of not only capable providing high efficiency like diesel engine combustion, but also producing much lowLarge Eddy Simulation (LES) modeling is developed to study homogeneous charge compression ignition (HCCI) combustion under different engine operation and mixture conditions, including real engine configurations and generic test cases. A previously developed HCCI model has been validated by comparing the simulation results with engine experiments. A new spark-assisted HCCI (SACI) combustion model h

Holistic Simulation of Mobile Robot and Sensor Network Applications Using TrueTime

The RUNES project defines a complex road tunnel scenario involving multiple mobile robots navigating in sensor network environment. In this paper, a TrueTime simulation model of the tunnel scenario is developed. The TrueTime simulator allows concurrent simulation of the physical robots and their environment, the software in the nodes, the radio communication, the network routing, and the ultra-sou

’Assimilitis.’ Joseph Roth – Eastern Jew, Cosmopolitan, European

Joseph Roth was a wanderer. Born in a Galizian shtetl, in the periphery of the Danube Monarchy, he went to Vienna, Berlin, and Paris, became socialist, monarchist, European, cosmopolitan. And yet remained East European Jew. Relentlessly on the move, and the embodiment of a Jewish and a modern destiny, Roth travelled through Europe and lived and wrote his novels and feuilletons in hotels and cafés,

The influence of NO on the occurence of autoignition in the end-gas of SI-engines

Full-cycle simulations of a spark ignition engine running on a primary reference fuel have been performed using a two-zone model. A detailed kinetic mechanism is taken into account in each of the zones, while the propagating flame front is calculated from a Wiebe function. The initial conditions for the unburned gas zone were calculated as a mixture of fresh gas and rest gas. The composition of th

Redifining teaching - An activity theoretical study of school practice in Sweden

The issue of this presentation is how teachers in the Swedish compulsory school have redefined their jobs as a result of new demands that have emerged during the restructuring in the 1990’s. Earlier, the teachers defined their jobs in terms of good teaching, e.g. transforming the subject matter in order to make it accessible. By using activity theory as a perspective for analysing qualitative data

MAPK-associated proteins in Arabidopsis thaliana

Abstract Mitogen-Activated Protein Kinases (MAPKs) are signalling proteins that are highly conserved among eukaryotes. They are involved in many biological pathways including cell differentiation and response to different stress situations. The MAPK cascade is composed of three signalling kinases, MAP3K, MAP2K and MAPK, which phosphorylate each other in a sequential manner. The different MAPK sub
