  1. 1. Geometric Models of Similarity

    Författare :Mikael Johannesson; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; symmetry; similarity; separable dimensions; prominence; multidimensional scaling; Minkowski metric; machine learning; integral dimensions; familiarity; geometric models; distance metric; asymmetry; conceptual spaces; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Geometry; algebraic topology; Geometri; algebraisk topologi;

    Sammanfattning : This dissertation examines and discusses some phenomena related to the geometric representation of similarity. It takes its inspiration from the existing body of empirical research within the fields of perceptual and cognitive psychology, but also connects to certain areas of machine learning. LÄS MER

  3. 2. Integral and local AC-susceptibility : instrumentation and applications

    Författare :Valter Ström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : This thesis presents my mostly unpublished experimental work related to two major contributions with the design of: A high precision and versatile bulk average(or integral) AC-susceptometer and its application to investigations of exchange anisotropy in Co multilayers. A novel Local Susceptibility measurement technique exploiting the narrow gap in inductive ring-heads in magnetic recording technology. LÄS MER

  4. 3. Design and Evaluation of a Compact 15 kW PM Integral Motor

    Författare :Peter Thelin; KTH; []
    Nyckelord :integral motor; integrated motor drive; PM motor; PMSM; compact motor; filter coil; airgap flux density; axial leakage;

    Sammanfattning : This thesis deals with the integral motor of tomorrow, and particularly with a variable speed, sensorless permanent magnet synchronous motor with an integrated converter. The rated power is 15 kW at 1500 r/min. The outer dimensions are approximately the same as for the equivalent standard induction motor.Control strategies for pumps and fans, i. LÄS MER

  5. 4. Weighted multidimensional integral inequalities and applications

    Författare :Sorina Barza; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : In this thesis some new weighted integral inequalities for monotone functions in higher dimensions are proved. These results extend previous results in one dimension, and also those in higher dimensions for particular choices of the weights (power weights, etc.). All inequalities are sharp. LÄS MER

  7. 5. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications

    Författare :Kristin Persson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extinction theorem; inverse source problem; integral representation; radome diagnosis; near-field transformation;

    Sammanfattning : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. LÄS MER
