  1. 1. Computational identification of RNA and protein components from the Signal Recognition Particle

    Författare :Magnus Alm Rosenblad; Göteborgs universitet; []
    Nyckelord :signal recognition particle; SRP; RNA secondary structure; non-coding RNA;

    Sammanfattning : Problem. The signal recognition particle (SRP) is a ribonucleoprotein particle that targets proteins to the endoplasmic reticulum in eukaryotes, to the plasma membrane in Archaea and Bacteria and to the thylakoid membrane in chloroplasts of photosynthetic organisms. It has one RNA component and 1 6 proteins. LÄS MER

  3. 2. Machine learning using approximate inference : Variational and sequential Monte Carlo methods

    Författare :Christian Andersson Naesseth; Thomas Schön; Fredrik Lindsten; Iain Murray; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Automatic decision making and pattern recognition under uncertainty are difficult tasks that are ubiquitous in our everyday life. The systems we design, and technology we develop, requires us to coherently represent and work with uncertainty in data. LÄS MER

  4. 3. Position Estimation in Uncertain Radio Environments and Trajectory Learning

    Författare :Yuxin Zhao; Fredrik Gunnarsson; Fredrik Gustafsson; Carsten Fritsche; Henk Wymeersch; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : To infer the hidden states from the noisy observations and make predictions based on a set of input states and output observations are two challenging problems in many research areas. Examples of applications many include position estimation from various measurable radio signals in indoor environments, self-navigation for autonomous cars, modeling and predicting of the traffic flows, and flow pattern analysis for crowds of people.

  5. 4. Ribosome Associated Factors Recruited for Protein Export and Folding

    Författare :Amanda Raine; Jarl Wikberg; Harris Bernstein; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Signal recognition particle; trigger factor; ribosomes; protein folding; membrane targeting; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : Protein folding and export to the membrane are crucial events in the cell. Both processes may be initiated already at the ribosome, assisted by factors that bind to the polypeptide as it emerges from the ribosome. LÄS MER

  7. 5. The search for a standard model Higgs at the LHC and electron identification using transition radiation in the ATLAS tracker

    Författare :Ulrik Egede; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; tracker; Large Hadron Collider; pion rejection; pattern recognition; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1998:Egede;

    Sammanfattning : The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. LÄS MER
