  1. 1. On Communication and Flocking in Multi-Robot Systems

    Författare :Magnus Lindhé; Karl Henrik Johansson; Magnus Egerstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; robotics; Automatic control; Reglerteknik;

    Sammanfattning : Coordination of multi-robot systems to improve communication and achieve flocking is the topic of this thesis. Methods are proposed for mobile autonomous robots to follow trajectories in a way that improves communications with a base station. Further, a decentralized algorithm is presented that yields flocking with obstacle avoidance. LÄS MER

  3. 2. Optics of coated paperboard : Aspects of surface treatment on porous structures

    Författare :Erik Bohlin; Caisa Johansson; Magnus Lestelius; Per Edström; Per-Åke Johansson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Calendering of coated and uncoated paper is widely used to enhance optical properties such as gloss and print quality. The aim of this thesis is to characterize coatings and prints, and to validate models using experimental results from optical measurements of physical samples. Calendering of coated paper often leads to a brightness decrease. LÄS MER

  4. 3. High pressure and high temperature behavior of TiAlN

    Författare :Niklas Norrby; Magnus Odén; Mats Johansson Johansson; Helen Blomqvist; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This licentiate thesis mainly reports about the behavior of arc evaporated TiAlN at high pressures and high temperatures. The extreme conditions have been obtained in metal cutting, multi anvil presses or diamond anvil cells. Several characterization techniques have been used, including x-ray diffraction and transmission electron microscopy. LÄS MER

  5. 4. Adjusting to the extreme : Thermal adaptation in a freshwater gastropod

    Författare :Magnus Johansson; Laurila Anssi; Robby Stoks; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radix balthica; Lake Mývatn; geothermal springs; thermal adaptation; isolation by environment; population structure; gene flow; cogradient variation; AFLP; thermal preference; CTmax; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Sammanfattning : Temperature is a ubiquitous force influencing biological processes ranging from cellular responses to life span. The thermal environment for many organisms is predicted to change with globally increasing temperatures and studies conducted in natural systems incorporating various evolutionary forces, such as gene flow, is needed.

  7. 5. Att bära världen på sina axlar : Miljövetares uppfattningar av och förhållningssätt till miljöproblem och sin profession

    Författare :Magnus Johansson; Pedagogik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental education; professional competence; phenomenology; higher education; phenomenographic research; education for sustainable development; environmental education;

    Sammanfattning : The aim of the thesis is to investigate experiences of and ways of relating to environmental issues and towards their profession among a group of graduates in environmentla science. The respondents were either in the end of or had completed an educational program in Environmental sciences with a social science perspective offered at Malmö University. LÄS MER
