    Abstract : With the development of communication and radar sensing technology, people are able to seek for a more convenient life and better experiences. The fifth generation (5G) mobile network provides high speed communication and internet services with a data rate up to several gigabit per second (Gbps). READ MORE

  4. 2. A Discrete Dipole Approximation Forward Solver for Microwave Breast Imaging

    Author : Samar Hosseinzadegan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave imaging; forward problem; breast cancer; tomography; computation time.;

    Abstract : Breast cancer has the highest incidence rate of cancers in women worldwide. Early detection results in a higher survival rate. Drawbacks in conventional imaging modalities, including painful exams, have limited periodic breast screening. READ MORE

  5. 3. Classical molecular dynamics simulations of collision-induced absorption : method development and evaluation

    Author : Wissam Fakhardji; Magnus Gustafsson; Javier Martin-Torres; Jean-Michel Hartmann; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Physics; Tillämpad fysik;

    Abstract : In this thesis collision-induced absorption (CIA) coefficients are computed using molec-ular dynamics (MD) simulations. Part I is dedicated to the theoretical frame of the method, from the classical theory radiation to the derivation of an absorption coefficient. READ MORE

  6. 4. On the effects of surface roughness in lubrication

    Author : Andreas Almqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Tribology is a multidisciplinary field defined as the science and technology of interacting surfaces in relative motion, and embraces the study of friction, wear and lubrication. A typical tribological application is the rolling element bearing. READ MORE
