  1. 1. Mathematics Communication within the Frame of Supplemental Instruction : Identifying Learning Conditions

    Författare :Annalena Holm; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATD: Anthropological Theory of Didactics; upper secondary school; Supplemental instruction; learning conditions; SOLO: Structure of the Observed Learning Outcome; Fysicumarkivet A:2014:Holm;

    Sammanfattning : In the Swedish context teaching at primary and secondary school is combined with collaborative exercises in a variety of subjects. These collaborative moments can be in the form of mini projects that groups of students are supposed to present to the classmates when fulfilled. LÄS MER

  3. 2. III–V Nanowire Surfaces

    Författare :Martin Hjort; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; low energy electron microscopy; scanning tunneling spectroscopy; scanning tunneling microscopy; surface; III–V semiconductor materials; nanowire; photoemission electron microscopy; photoelectron spectroscopy; Fysicumarkivet A:2014:Hjort;

    Sammanfattning : This dissertation deals with the geometric and electronic structure of surfaces on III–V semiconductor nanowires (NWs). NWs made of InAs, GaAs, and InP have been studied using scanning tunneling microscopy/spectroscopy (STM/S), low energy electron microscopy (LEEM), photoemission electron microscopy (PEEM), and x-ray photoelectron spectroscopy (XPS).

  4. 3. Measurement Based Channel Characterization and Modeling for Vehicle-to-Vehicle Communications

    Författare :Taimoor Abbas; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-to-vehicle communications; IEEE 802.11p; Channel measurements; Channel modeling; propagation modeling; MIMO; intelligent transportation systems;

    Sammanfattning : Vehicle-to-Vehicle (V2V) communication is a challenging but fast growing technology that has potential to enhance traffic safety and efficiency. It can also provide environmental benefits in terms of reduced fuel consumption. LÄS MER

  5. 4. Analyses and Applications of the Peaceman--Rachford and Douglas--Rachford Splitting Schemes

    Författare :Erik Henningsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Splitting methods are widely used as temporal discretizations of evolution equations. Such methods usually constitute competitive choices whenever a vector field can be split into a sum of two or more parts that each generates a flow easier to compute or approximate than the flow of the sum.

  7. 5. Higher-Order Regularization in Computer Vision

    Författare :Johannes Ulén; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Regularization; Segmentation; Dense Stereo;

    Sammanfattning : At the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. LÄS MER
