21. Price measurement and index construction : some contributions to theory and application
Sammanfattning : Four different problems are treated, all concerned with problems arising when compiling price indexes in official statistics. One deals with the computation of so called elementary aggregates, low level indexes for single products, when proper weights for the observations are not available. LÄS MER
22. Learning and Evaluating the Geometric Structure of Representation Spaces
Sammanfattning : Efficient representations of observed input data have been shown to significantly accelerate the performance of subsequent learning tasks in numerous domains. To obtain such representations automatically, we need to design both i) models that identify useful patterns in the input data and encode them into structured low dimensional representations, and ii) evaluation measures that accurately assess the quality of the resulting representations.

23. Preservice teachers' view on the concept of function : a study including the utilization of concept maps
Sammanfattning : The thesis consists of an overview of the subject, where in particular three papers are put into a frame. The overview part consists of: an introduction, a short description of some related research and theoretical framework, a summary of papers I-III and the concluding discussion. LÄS MER
24. Some new Hardy-type Inequalities for integral operators with kernels
Sammanfattning : This Licentiate thesis deals with the theory of Hardy-type inequalities in anew situation, namely when the classical Hardy operator is replaced by amore general operator with kernel. The kernels we consider belong to thenew classes O+ n and O-n , n = 0; 1; :::, which are wider than co-called Oinarovclass of kernels. LÄS MER
25. Technology and studies of electron transport in InAs nanowire junctions
Sammanfattning : The topic of this thesis is technology and experimental studies of electron transport in Indium Arsenide (InAs) nanowires and InAs nanowire junctions. The aim of this work has been fabrication of nanoelectronic devices which have possibilities for future nanoelectronics. LÄS MER
