  2. 1. An Optimisation Approach to Cartographic Generalisation

    Author : Lars Harrie; Centrum för geografiska informationssystem (GIS-centrum); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; incremental generalisation; multiple representation; least-squares method; optimisation; cartographic constraints; displacement; cartographic generalisation; graphic generalisation; map production; object-oriented spatial databases; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik;

    Abstract : Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. READ MORE

  4. 2. Estimation of Machining System Dynamic Properties - Measurement and Modelling

    Author : Tomas Österlind; Andreas Archenti; Mihai Nicolescu; Leif Kari; Amir Rashid; Thomas Abrahamsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Operational dynamic parameters; Displacement map; Contactless excitation and response system; SRA - Production; SRA - Produktion; Production Engineering; Industriell produktion;

    Abstract : Dynamic characteristics of machining systems are analysed for improved understanding of both structural and process properties. The thesis stresses the use of testing methods under operational like conditions as these are more representative of closed loop systems, such as machining systems, as compared to conventional testing methods.

  5. 3. Generalisation Methods for Propagating Updates between Cartographic Data Sets

    Author : Lars Harrie; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiple representation database; automated cartographic generalisation; incremental generalisation; displacement; cartographic constraints; object-oriented database;

    Abstract : Automation is increasingly important in producing and maintaining cartographic data sets. This thesis deals with automatic methods to propagate updates between cartographic data sets. READ MORE

  6. 4. Magnetic map sense in animals: effects of geographic and magnetic displacements

    Author : Jannika Boström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oenanthe oenanthe; skylight polarization; geomagnetic map; geomagnetic field; endogenous migration programme; migratory fuelling; orientation; animal navigation;

    Abstract : Migration research is a large and diverse field and in my thesis I have focused on the impact of geomagnetic cues on animal orientation, navigation and migratory fuelling. Several animal species from widely different taxa possess the ability to sense and make use of geomagnetic information during migratory or homing events. READ MORE

  7. 5. Manipulation of Light with Transformation Optics

    Author : Wei Yan; Min Qiu; Niels Asger Mortensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transformation optics; Maxwell’s equations; invisibility cloaks; compensated bilayer; perfect imaging; optical illusion; nihility media; α media; Optics; Optik;

    Abstract : Transformation optics, a recently booming area, provides people a new approach to design optical devices for manipulating light. With transformation optics, a lot of novel optical devices are proposed, such as invisibility cloaks, optical wormholes, optical black holes, illusion devices. READ MORE
