The thesis comprises an analysis of the heat transfer phenomenon in solid oxide fuel cells (SOFCs) and a description of various transport phenomena in a solid oxide electrolysis cell. Both devices are encompassed under the solid oxide electrochemical cell concept. Moreover, a CFD model of an SOEC was developed to study the behavior of the cell under different conditions of operating and structural
This study explored if the visual gender representations (androgynous, male, or female) of an embodied agent would influence students’ perceptions of their agent and their attitudes toward the agent as their conversational partner. The study also explored if students’ gender and cultural background would interact with the agent’s visual gender to influence their perceptions and attitudes. Particip
For the first time, the capacity gain of multisector cooperative multiple-input multiple-output(MIMO) using all three 120 degree sectors of a base station (BS) site is studied in a measured urban macrocellular environment at 2.65GHz. The results reveal that the mean uplink capacity gain exceeds 40% in as much as 1/4 of the coverage area, relative to the best single-sector link with no cooperation.
With its long history of about three thousand years of statehood and with its geographic situation in the Caucasus, at the cross-roads of the Christian and Muslim worlds, Georgia represents an interesting picture in terms of linguistic (and not only linguistic) diversity. During the Soviet period and even since the Russian expansion in Georgia (19th century), minority and majority languages and id
Det mullrar kring läkemedel . Allt fler patienter kräver allt mer, samtidigt som läkemedelsföretagen utvecklar mer och mer avancerade mediciner. Åtminstone retoriskt är dessa tendenser varandras förutsättningar och förstärkningar. Men i praktiken kan mycket väl läkemedelsföretag och patienter vara på väg åt olika håll, i en gemensam omedvetenhet om att de ännu inte ens börjat leta efter någon före
