1. 16. Coding of Three-dimensional Video Content : Diffusion-based Coding of Depth Images and Displacement Intra-Coding of Plenoptic Contents

   Författare :Yun Li; Mårten Sjöström; Ulf Jennehag; Roger Olsson; Touradj Ebrahimi; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In recent years, the three-dimensional (3D) movie industry has reaped massive commercial success in the theaters. With the advancement of display technologies, more experienced capturing and generation of 3D contents, TV broadcasting, movies, and games in 3D have entered home entertainment, and it is likely that 3D applications will play an important role in many aspects of people's life in a not distant future.

4. 18. Assessment of Left Ventricular Function and Hemodynamics Using Three-dimensional Echocardiography

   Författare :Kambiz Shahgaldi; Lars-Åke Brodin; Michael Haney; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Three-dimensional echocardiography; heart chambers; flow-volume loop; left ventricular ejection fraction; visualization; left ventricular stroke volume; left ventricular outflow tract; and single-heartbeat; Medical technology; Medicinsk teknik;

   Sammanfattning : Left ventricular (LV) volumes and ejection fraction (EF) are important predictors of cardiac morbidity and mortality. LV volumes provide valuable prognostic information which isparticularly useful in the selection of therapy or determination of the optimal time for surgery. LÄS MER

5. 19. On Turbulent Wall Jets

   Författare :Hans Abrahamsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; self-preservation; similarity theory; scaling laws; local flow reversals; high turbulence levels; turbulent kinetic energy budget; two-dimensional; turbulent; hot-wire anemometry; wall jet; three-dimensional; pulsed hot-wire anemometry;

   Sammanfattning : An experimental investigation of the two- and three-dimensional turbulent wall jets has been conducted. The measurements have been performed using different hot-wire techniques in large scale wall jet facilities, and the measurements were focused on the fully-developed region of the flow. LÄS MER

7. 20. Nanoelectronic Devices Based on Low-Dimensional Semiconductor Structures

   Författare :Daniel Wallin; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; InGaAs InP; GaAs AlGaAs; ballistic transport; quantum transport; low-dimensional structures; two-dimensional electron gas; quantum dot; three terminal ballistic junction; nanowire;

   Sammanfattning : The present thesis reports on results from the fabrication technology development and the corresponding electrical transport measurements of low-dimensional semiconductor structures. The focus of the work has been directed towards two parts: the ballistic transport in nanostructure devices at room temperature, and the development of a charge-sensing technique for quantum dots (QD) in nanowires.
