1. 1. Interpretation and Alignment of 2D Indoor Maps : Towards a Heterogeneous Map Representation

   Författare :Saeed Gholami Shahbandi; Björn Åstrand; Roland Philippsen; Antanas Verikas; Patric Jensfelt; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Mobile Robots; Autonomous Robots; Robot Perception; Robotic Mapping; Map Interpretation; Semantic Mapping; Place Categorization; Place Labeling; Semantic Annotation; Map Alignment; Region Segmentation; Region Decomposition; Map Representation; Heterogeneous Representation;

   Sammanfattning : Mobile robots are increasingly being used in automation solutions with notable examples in service robots, such as home-care, and warehouses. Autonomy of mobile robots is particularly challenging, since their work space is not deterministic, known a priori, or fully predictable. LÄS MER

3. 2. Map-reading and wayfinding

   Författare :Torgny Ottosson; Göteborgs universitet; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children; cognition; cognitive psychology; map skills; maps; orienteering; phenomenography; phenomenology; preschool children; primary education;

   Sammanfattning : The aim of the study is to make an analysis of map-reading as a cognitive phenomenon, with the use of a map for finding one's way as the specific focus. As a point of departure, the nature of human beings' knowledge of spatial relationships in their physical environment (here termed macro-spatial relations) is discussed. LÄS MER

4. 3. Exercising Mathematical Competence: Practising Representation Theory and Representing Mathematical Practice

   Författare :Anna Ida Säfström; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematical competence; exercising competencies; young children; whole number arithmetic; tertiary level; proving; highest weight representation; tensor product decomposition; skew-symmetric matrix; moment map; infinite dimensional unitary representation; highest weight representation;

   Sammanfattning : This thesis assembles two papers in mathematics and two papers in mathematics education. In the mathematics part, representation theory is practised. Two Clebsch-Gordan type problems are addressed. LÄS MER

5. 4. Kvinnors politiska representation i ett jämförande perspektiv - nationell och lokal nivå

   Författare :Jessika Wide; Svante Ersson; Christina Bergqvist; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; women in politics; descriptive representation; female representation; gender and politics; political parties; gender quotas; parliaments; municipal councils; Political science; Statsvetenskap;

   Sammanfattning : The purpose of this dissertation is to map and analyze the spatial and temporal variation in women’s political representation at both the national and local level. In the dissertation it is argued that women’s political representation is the outcome of the interplay between structures, institutions and actors. LÄS MER

7. 5. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

   Författare :Gabrielle Flood; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time of arrival; TOA; Time-difference of arrival; TDOA; Subsample methods; Uncertainty measure; Constant offset; RANSAC; Map merging; Map fusion; Change detection; Collaborative SLAM; Structure from motion; SfM; SLAM; Mapping; Localisation; Registration; Sparse maps; Point clouds;

   Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER
