  2. 21. Micromachined Microwave Sensors for Non-Invasive Skin Cancer Diagnostics

    Author : Fritzi Töpfer; Joachim Oberhammer; Lennart Emtestam; Milica Popovic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave probe; microwave sensor; skin cancer diagnostics; malignant melanoma; microwave reflectometry; non-invasive diagnostics; micromachining; dielectric-rod waveguide; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Malignant melanoma is one of the cancers with the highest incident rates. It is also the most dangerous skin cancer type and an early diagnosis is crucial for the successful treatment of malignant melanoma patients. READ MORE

  4. 22. Electromagnetic Simulation, Analysis and Design with Application to Antennas and Radar Absorbers

    Author : Alireza Motevasselian; Lars Jonsson; Lars Pettersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present thesis considers two different subjects in the research area of electromagnetics. The first part is concerned with antenna design and the second with radar absorbers and rasorber.In the first part, a novel excitation technique for cylindrical dielectric resonator antennas is introduced to produce circular polarization.

  5. 23. Charge Transport in Transition Metal Oxide Thin Films and Electrochromic Devices

    Author : AnnaKarin Jonsson; Bengt-Erik Mellander; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Teknisk fysik; Engineering physics; Teknisk fysik; Solid State Physics; Fasta tillståndets fysik;

    Abstract : Thin film devices for windows, mirrors, space applications and other purposes, have become an essential part of modern technology. A great advantage with a thin film device is the small amount of material used and the compact volume of the device. READ MORE

  6. 24. Efficient Adaptive Algorithms for an Electromagnetic Coefficient Inverse Problem

    Author : John Bondestam Malmberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coefficient inverse problem; inverse scattering; Maxwell’s equations; approximate global convergence; finite element method; adaptivity; ; a posteriori error analysis;

    Abstract : This thesis comprises five scientific papers, all of which are focusing on the inverse problem of reconstructing a dielectric permittivity which may vary in space inside a given domain. The data for the reconstruction consist of time-domain observations of the electric field, resulting from a single incident wave, on a part of the boundary of the domain under consideration.

  7. 25. Unsaturated Phase Environmental Processes in MSWI Bottom Ash

    Author : Aamir Ilyas; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bottom Ash; Frequency Domain; Hydrogen Recovery; Leaching; Microbial Respiration; Eco-toxicity; Solid Waste;

    Abstract : Every year, Sweden produces 1.5 million tons of incineration residues from waste to energy plants. Among these residues bottom ash(BA) due to its large volume and good geotechnical quality can be reused as an alternative construction material. READ MORE
