1. 1. Compression Techniques for Code Size and Data Bandwidth Reduction

   Författare :Martin Thuresson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; static code compression; high performance; Computer architecture; data link compression;

   Sammanfattning : A challenge in the design of high performance computer systems is how to transferdata efficiently between main memory and the faster and smaller memory located onthe processor chip. Main memory holds both the program to be executed and the datait needs to perform its tasks. LÄS MER

3. 2. Cell-penetrating peptide targeting mitochondria : Design, synthesis, characterization, and biological effects

   Författare :Carmine Pasquale Cerrato; Ülo Langel; Lena Mäler; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell-penetrating peptide; mitochondrial targeting; ROS reduction; mitochondrial membrane potential; antioxidant activity; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : More than twenty years after the discovery of the first cell-penetrating peptide (CPP), a large number of both naturally occurring as well as engineered CPPs have been discovered. Generally, CPPs are short polycationic sequences of less than 30 amino acids that are able to translocate different cargoes into cells. LÄS MER

4. 3. Dynamics and Mechanisms of Adaptive Evolution in Bacteria

   Författare :Song Sun; Dan Andersson; Diarmaid Hughes; Josep Casadesús; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptive evolution; mutation; genome rearrangements; antibiotic resistance; gene amplification; genome reduction; directed evolution; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

   Sammanfattning : Determining the properties of mutations is fundamental to understanding the mechanisms of adaptive evolution. The major goal of this thesis is to investigate the mechanisms of bacterial adaptation to new environments using experimental evolution. LÄS MER

5. 4. Reduction of metal artifacts in MR imaging of patients with total hip arthroplasty

   Författare :Gunilla Müller; Malmö Diagnostisk radiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging. Musculoskeletal. Hip. Hip prosthesis. Complications. Metal artifact. Metal artifact-reducing sequences MARS . Phantom studies. Artifact measurement. Image distortion.;

   Sammanfattning : Aims of the studies: To apply and compare MR imaging metal artifact reducing sequences (MARS) including subtraction imaging after contrast application in patients with metal-on-metal (MoM) hip prostheses, investigate the prevalence and characteristics of periprosthetic abnormalities, as well as their relation with pain and risk factors.

7. 5. Variation Control in Virtual Product Realization - A Statistical Approach

   Författare :Kristina Wärmefjord; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quality control; contact modeling; Variation simulation; welding simulation; spot welding sequence; inspection point reduction; fixture repeatability;

   Sammanfattning : All manufacturing processes are afflicted by variation, which leads to products that may not fulfill assembly, functional or esthetical requirements. The variation in the final product originates from variation in individual parts and assembly processes. LÄS MER
