2. 1. GNSS hardware biases in code and carrier phase observables

   Author : Martin Håkansson; Milan Horemuz; Anna B. O. Jensen; Lambert Wanninger; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS; GNSS positioning; hardware biases; phase biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; satellite dependency; characterization; android; mass market; Group delay variations; nadir dependence; ionosphere modeling; ionospheric tomography; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

   Abstract : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. The presence of biases in GNSS observations might affect the accuracy in precise GNSS positioning applications, and might also be of relevance in other GNSS applications. READ MORE

4. 2. Hardware biases and their impact on GNSS positioning

   Author : Martin Håkansson; Anna B. O. Jensen; Milan Horemuz; Jan Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS positioning; Hardware biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Abstract : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. These biases influence the accuracy in precise GNSS positioning if not handled properly. READ MORE

5. 3. Optimization of empty freight car distribution in scheduled railways

   Author : Martin Joborn; Warren B. Powell; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In a railway system, empty freight cars have to be repositioned to enable transportation demand to be fulfllled. These empty car movements are planned and implemented in the empty freight car distribution process. READ MORE

6. 4. Macrolide Antibiotics in Bacterial Protein Synthesis

   Author : Martin Lovmar; Måns Ehrenberg; Tanel Tenson; Peter B. Moore; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; protein synthesis; macrolides; resistance; initiation of translation; non-competitive inhibitors; kinetics; translation accuracy; proof-reading; Biokemi; Biochemistry; Biokemi;

   Abstract : Macrolides are a large group of clinically relevant antibiotics that inhibit protein synthesis by binding to the large ribosomal subunit in the peptide exit tunnel, close to the peptidyl transferase center (PTC). We have shown that the peptide length of the resulting peptidyl-tRNA drop-off products is proportional to the distance between the PTC and the respective macrolide in the tunnel. READ MORE

7. 5. Quality in Learning in Rwandan Higher Education : Different stakeholders’ perceptions of students’ learning and employability

   Author : Penelope B. Mbabazi; Andreas Fejes; Sofia Nyström; Lars-Owe Dahlgren; Martin Stigmar; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Students’ learning; employability; higher education; Rwanda; Studenters lärande; anställningsbarhet; högre utbildning; Rwanda;

   Abstract : The aim of the thesis is to investigate quality in learning in higher education in Rwanda by focusing on students’ learning and their employability. This focus allows for an understanding of key challenges for Rwandan higher education to emerge, at a time when more and more students are enrolling. READ MORE
