1. 1. Single Base Station mmWave Radio Positioning, Mapping, and SLAM

   Författare :Yu Ge; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DA; positioning; 5G; experimental validation; RFS; SLAM; fusion; mmWave; diffuse multipath; mapping; single BS;

   Sammanfattning : Fifth-generation (5G) communication systems in Frequency Range 2, operating above 24 GHz and utilizing mmWave signals, showcase distinct properties that open up new possibilities in positioning, mapping, and simultaneous localization and mapping (SLAM). The combination of large bandwidth, extensive antenna arrays, and high carrier frequency results in geometric-based signals, and unprecedented delay and angle resolution. LÄS MER

3. 2. Functional Organization of Cerebellar Modules Controlling Forelimb Movements: Climbing and Mossy Fibre Input and Motor Output via the Red Nucleus and Motor Cortex

   Författare :Henrik Jörntell; Neurofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; neurofysiologi; Neurology; neuropsychology; neurophysiology;

   Sammanfattning : A modular organization has recently been described for the cerebellar control system comprising the forelimb areas of the C1/C3/Y zones in the cerebellar cortex and nucleus interpositus anterior (NIA) of the cat. A module is a group of cells in NIA which receives homogenous climbing fibre input via Purkinje cells that belong to the same set of microzones in the C1/C3/Y zones. LÄS MER

4. 3. Evolutionary Mechanisms Shaping Bacterial Translation Termination

   Författare :Shreya Pundir; Suparna Sanyal; Martin Ott; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Protein; Release Factor; Translation; Termination; Stop codon; Evolution; Mutation; Kinetics; Cryo-EM; Molekylär biovetenskap; Molecular Life Sciences;

   Sammanfattning : Translation termination in bacteria involves precise reading of stop codons (UAA, UAG, UGA) and coordinated peptidyl-tRNA hydrolysis by the class-I release factors (RFs) on the ribosome (70S). This thesis investigates the evolutionary and post-translational modification mechanisms of these RFs and the concurrent effect on bacterial translation termination. LÄS MER

5. 4. Predictors of disease onset and progression in early rheumatoid arthritis : A clinical, laboratory and radiological study

   Författare :Ewa Berglin; Solbritt Rantapää-Dahlqvist; Thomas Skogh; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; early; rheumatoid; arthritis; anti-CCP; antibodies; factors; radiological; outcome; disease; onset; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

   Sammanfattning : To diagnose rheumatoid arthritis (RA) during the early stages of the disease is often difficult. The disease course shows great inter-individual variation from mild, self-limiting to very severe destruc-tive disease with extra-articular manifestations. LÄS MER

7. 5. Innovative Construction of Student Residences : Frameup Project

   Författare :Pedro António Pimenta de Andrade; Anders Sjelvgren; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Sammanfattning : In the majority of university cities in Sweden, a strong demand for student accommodations has initiated various development and research projects focusing on costs reduction and fast execution. The present thesis brings up a solution based on the development of a feasible assembly concept and process, for a Modular Building erection, where prefabricated 3D Modules are assembled into a sway steel frame.
