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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Niklas Norrby; Magnus Odén; Mats Johansson Johansson; Helen Blomqvist; Linköpings universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

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

    Author : Magnus Johansson; Laurila Anssi; Robby Stoks; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. Between logics

    Author : Magnus Johansson; Företagsekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; customization; competence; Value creation logics; value constellation; industrial organizations;

    Abstract : Industrial organizations rely, to an increasing extent, on intangible resources such as the knowledge and competence of highly skilled workers. This makes them successively similar to organizations closely associated with highly skilled workers, such as professional service firms. READ MORE
