  2. 16. A Class of Renewal Processes in Random Environments

    Author : David Svensson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; point process; renewal process; random environment; coupling; regeneration; failure rate; Poisson embedding; asymptotics; stochastic domination; stochastic monotonicity; renewal process;

    Abstract : This paper deals with a generalization of the class of renewal processes with absolutely continuous life length distribution, obtained by allowing a random environment to modulate the stochastic intensity of the renewal process. The random environment is a birth and death process with a finite state space. READ MORE

  4. 17. Large-Signal Modeling of Microwave Transistors

    Author : Lars Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large-signal; HEMT; non-linear models; de-embedding; high-efficiency; class-E amplifier; LDMOS; HBT; HFET; model parameter extraction; microwave transistors;

    Abstract : The development of computer aided design tools for microwave circuit design has increased the interest for accurate transistor models. The circuit complexity has grown as the CAD tools have been improved and the need to predict how non-linear circuits behave has also been increased. READ MORE

  5. 18. Quaternion Orders and Ternary Quadratic Forms Orders of Class Number One and Representations of Algebraic Integers by Quadratic Forms

    Author : Elise Björkholdt; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quaternion order; ternary quadratic form; class number; even Clifford algebra; quaternion algebra; embedding number; 11E12; 16H05; 11E20; 11E25; 11E88; even Clifford algebra;

    Abstract : Let R be the ring of integers in a totally real quadratic field K. The purpose of the thesis is to study totally definite quaternion R-orders and representations of elements in R by totally positive definite integral ternary quadratic forms. The thesis consists of three papers. READ MORE

  7. 20. Flash Diffractive Imaging in Three Dimensions

    Author : Tomas Ekeberg; Janos Hajdu; Keith Nugent; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray; diffraction; mimivirus; three dimensional; phase retrieval; EMC; manifold embedding; CXI; FEL; free-electron laser; single particle; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : During the last years we have seen the birth of free-electron lasers, a new type of light source ten billion times brighter than syncrotrons and able to produce pulses only a few femtoseconds long. One of the main motivations for building these multi-million dollar machines was the prospect of imaging biological samples such as proteins and viruses in 3D without the need for crystallization or staining.
