As a first step towards synthesis of speaker age the hypothesis that spectral cues may be more important for age perception than F0 and duration was tested in a pilot listening experiment with male speaker stimuli consisting of natural, synthesized and resynthesized isolated words. Results indicate that spectral information is dominant over pitch as cues for age. Slow speech rate also seems to be
Syrian monasticism has often been judged by its extremes, with Symeon the Stylite as the prime example of someone leaving the human world behind to reach for God. In this interpretation, hagiographical renderings seem only to underline an opposition between sacred and civil spheres, between the cells of the ascetics and human society. With this article, however, I wish to call such a conclusion in
Modeling and understanding the vortex breakdown is a key issue of modern Lean Premixed Combustors. The main difficulty of the problem is the unsteady behavior of this type of flow: Large structures resulting from vortex breakdown and the swirling shear-layers, affect directly the flame stabilization leading to heat-release fluctuations and combustion instabilities. Consequently, one needs to captu

Popular Abstract in Swedish I syfte att upprätthålla en optimal miljö för alla kroppens celler har högre stående djur utvecklat blodcirkulationen genom vilken syre- och andra närings ämnen transporteras till vävnader via artärer och de mindre arteriolerna, medan slaggprodukter förs bort med venerna. Utbytet av näringsämnen och slaggprodukter mellan blod och vävnad sker genom kärlväggen i kroppens Disturbances in microvascular function may be important for tissue damage in many disease states. Prostacyclin, a substance produced by endothelial cells, is important for the maintenance of normal vascular homeostasis and is a potential drug for treatment of microvascular dysfunction, but indications and optimal dosage remains to be established. In the present thesis we evaluated the capillary fi
This text describes, from a cultural perspective, the role of higher education teacher training, in the systemic development of teaching and learning in higher education institutions. Three main organisational levels are identified: micro, meso and macro; and implications for and of teacher training on each level is discussed. Even though the emphasis is on the meso level, suggestions are made for

We investigated lip and tongue movements of diphthongisation of /uː/ in the Malmöhus dia- lect, which is spoken in the very south of Swe- den. Articulographic and acoustic data of ten native speakers were collected and analysed. Acoustic analysis revealed fairly stable F1 and F3, but a considerable F2 movement through- out the diphthongisation, indicating that /uː/ is realised dynamically. Articul
This paper consists of two, somewhat disparate parts. In the first part, some experiences of two years of fieldwork are summarized, concentrating, as the subtitle suggests, on the very heart of phonetic fieldwork: the encounters and interviews with the informants. As a result of the fieldwork, the project now has access to recordings from approximately 1300 speakers of more than 100 dialects of Sw
Increasing noise regulations at urban airports force jet engine manufactures to develop and build more quiet engines. Over recent years, a significant reduction in fan and mechanical noise has been achieved. However, the jet exhaust is the principal source of noise. The acoustical field that is generated by a turboengine jet exhaust running near the ground level is considered. The full equations o
Two alternative Human-Machine-Interface solutions for in-vehicle speed support were evaluated in field trials in Hungary and Spain. Twenty vehicles on both test sites were equipped with two kinds of systems: 1) support via an Active Accelerator Pedal and 2) warning via beep signals and flashing red light when exceeding the speed limit. The test drivers drove one month with each system. Both system
Over the last fifty years the debate between modernism and postmodernism has surfaced in the disciplines of social sciences. Epistemologically, there is a shift away from the concept of a “found” world, “out there”, objective, knowable and factual, towards a concept of “constructed” worlds, thus problematizing postulates based on the autonomous, stable, unified, essentialized, coherent and integra
Performance demands put on combustion engines are ever increasing, e.g. demands on emissions and fuel consumption. The increased demands together with new combustion concepts increase the need for feedback engine and combustion control. Mathematical models are considered important in order to implement high performance feedback control, as well as to perform diagnostic functions in vehicles. Vario
