    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resonant-tunnelling diode; millimetre-wave spectrum; integrated transmitter; energy-efficiency; compact circuit; dielectric resonator antenna; transistor; wavelet generator; wideband.;

    Abstract : Radio systems, along with the ever increasing processing power provided by computer technology, have altered many aspects of our society over the last century. Various gadgets and integrated electronics are found everywhere nowadays; many of these were science-fiction only a few decades ago. READ MORE

  5. 3. The theory and practice of abrasive water jet cutting

    Author : Lars Ohlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : Abrasive Water Jet (AWJ) has grown to be an important industrial tool during the last decade. A great deal of effort has been put into describing the process. However, many of the most fundamental aspects of the process are still not fully understood, or described, and many questions have been left unanswered. READ MORE

  6. 4. Studies of Mesenchymal Progenitor Cells and Tumour Growth, Integrins and Matrix Metalloproteinases

    Abstract : In this thesis we characterize the effect of mesenchymal progenitor cells (MPCs) on tumour growth, and show that MPCs can have inhibitory effects on tumour development. We developed a method to subcutaneously transplant tumour cells, cultured in vitro in a pre-formed gelatin matrix, that made it possible to study the early phases of tumour development. READ MORE

  7. 5. New methods for movement technique development in cross-country skiing using mathematical models and simulation
