1. 1. Search for Gamma-ray Lines from Dark Matter with the Fermi Large Area Telescope

   Författare :Tomi Ylinen; Mark Pearce; Jan Conrad; Staffan Carius; James T. Linnemann; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fermi; Large Area Telescope; gamma-rays; dark matter; spectral lines; beam test; Physics; Fysik; Astroparticle physics; Astropartikelfysik;

   Sammanfattning : Dark matter (DM) constitutes one of the most intriguing but so far unresolved issues in physics. In many extensions of the Standard Model of particle physics, the existence of a stable Weakly Interacting Massive Particle (WIMP) is predicted. The WIMP is an excellent DM particle candidate.

3. 2. Theoretical Modeling and Near-Infrared Spectroscopy Monitoring of Vial Lyophilization

   Författare :Mikael Brülls; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ; simulation; monitoring; spectral peak area analysis; near-infrared spectroscopy; lyophilization; moisture; sublimation; vial; mathematical model;

   Sammanfattning : The research documented in this thesis was directed towards lyophilization of pharmaceuticals in vials (vial lyophilization) and it was focused on the design and control of this process. Theoretical modeling has considerable potential to guide experimental studies, thereby decreasing development time and improving the possibilities to achieve an optimal and robust process design.

4. 3. Noise diagnostics of Stationary and Non-Stationary Reactor Processes

   Författare :Carl Sunde; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; core-barrel vibrations; break-frequency method; wavelet; decay ratio; detector tube impacting; two-phase flow; spectral analysis; noise diagnostics;

   Sammanfattning : This thesis concerns the application of noise diagnostics on different problems in the area of reactor physics involving both stationary and non-stationary core processes. Five different problems are treated, divided into three different parts. LÄS MER

5. 4. Tissue Doppler in Spectral and Color ModeMethodological ConsiderationsNon-invasive Estimation of Left Ventricular Filling Pressures using the E/Em index

   Författare :Aristomenis Manouras; Lars Åke Brodin; Michael Henein; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue Doppler; Cardiology; Kardiologi;

   Sammanfattning : Aims: Tissue Doppler (TD) in spectral mode (spectral TD) and color TD are the two modalities available today in tissue velocity echocardiography (TVE). Measurements of left ventricular (LV) myocardial velocities and displacement may yield different results depending on the employed sonographic modality and the subjective adjustments during data analysis.

7. 5. A spectroscopic study of polymer : Carbon nanotube composites

   Författare :Andreas Müller; Ove Andersson; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : Since the identification of carbon nanotubes (CNTs) by Ijima in 1991, this material has become a subject of great interest and effort in science because of the outstanding physical properties it exhibits. CNTs can be thought of as graphene sheets rolled into seamless cylinders of various diameters and in principle infinite length. LÄS MER
