Hybrid method for the prediction of thermo-acoustic waves in an annular gas turbine combustion chamber

The acoustic field in an annular gas turbine combustion chamber with thirty burners has been studied using a hybrid approach. The acoustic field was determined by solving an inhomogeneous wave equation. The acoustic sources were provided by a low Mach number flow solver. The main focus was to determine the influence of nonuniform behavior and interactions of neighboring burners. For this reason th

Med sina montageverk och videoinstallationer har Lina Selander under de senaste åren framträtt som ett av Sveriges mest tankeväckande konstnärskap. Med en öppen, prövande hållning och en väl utvecklad rytm- och formkänsla utforskar hon relationerna mellan skilda medier, teknologier och material för att därigenom söka gränserna för vad som är möjligt att visa och säga.

”There Can Be Only One?” Towards a Post-Foundational Service Marketing Perspective.

The field of service marketing is in a state of flux, questioned from the ‘outside’ as well as from scholars ‘within’ the field. Its very foundation, the service definition, is subject to discussion. Three possible trajectories forward can be noticed among scholars from ‘within’ the field in this discussion; the abandonment of service as a general category, the formulation of a new, more defendabl

Professionalism in Retreat? How New Public Management has Affected the Swedish Doctors

In this paper the impact of New Public Management is issued in terms of its effects on the professionalism of the Swedish doctors, where professionalism is conceptualized, according to Freidson's (2001) definition, as "the institutional circumstances in which the members of an occupation rather than consumers or managers control work". Also the ideal type builds on the assumption that the conditio

Affective engagement in teachable agents

Students’ use of two different versions of a digital math game, one extended with a teachable agent, is compared. The purpose is to compare the affective engagement of student using the two different versions. An overall aim is to extend our knowledge of the paradigm Learning by Teaching.
