1. Grafisk och algebraisk representation : Gymnasieelevers förståelse av linjära funktioner
Sammanfattning : This thesis concerns upper secondary students’ understanding of algebraic and graphic representation of linear functions. Components of the students’ concept images, so-called ‘concept elements’, were studied as a way to capture their understanding. LÄS MER
2. Studies in knowledge representation : modeling change - the frame problem : pictures and words
Sammanfattning : In two studies, the author attempts to develop a general symbol theoretical approach to knowledge representation.The first study, Modeling change -the frame problem, critically examines the - so far unsuccessful - attempts to solve the notorious frame problem. LÄS MER
3. Torpets transformationer : Materialitet, representation och praktik från år 1850 till 2010
Sammanfattning : The concept of the croft (Sw. torp) is complex. From the 17th century crofts were small tenant holdings on a farm or estate. Along with changes in society since c. LÄS MER
4. Dexterous Grasping : Representation and Optimization
Sammanfattning : Many robot object interactions require that an object is firmly held, and that the grasp remains stable during the whole manipulation process. Based on grasp wrench space, this thesis address the problems of measuring the grasp sensitivity against friction changes, planning contacts and hand configurations on mesh and point cloud representations of arbitrary objects, planning adaptable grasps and finger gaiting for keeping a grasp stable under various external disturbances, as well as learning of grasping manifolds for more accurate reachability and inverse kinematics computation for multifingered grasping.

5. Mind in Action : Action Representation and the Perception of Biological Motion
Sammanfattning : The ability to understand and communicate about the actions of others is a fundamental aspect of our daily activity. How can we talk about what others are doing? What qualities do different actions have such that they cause us to see them as being different or similar? What is the connection between what we see and the development of concepts and words or expressions for the things that we see? To what extent can two different people see and talk about the same things? Is there a common basis for our perception, and is there then a common basis for the concepts we form and the way in which the concepts become lexicalized in language? The broad purpose of this thesis is to relate aspects of perception, categorization and language to action recognition and conceptualization. LÄS MER
