  2. 1. Analysis of Velocity Encoded Images --- With Applications in Cardiac MRI

    Author : Erik Bergvall; Lunds universitet; []
    Keywords : ;

    Abstract : The topic of the thesis is the analysis of velocity encoded medical images, acquired using magnetic resonance imaging or other means. The application in mind is to use such data to determine the motion and deformation of the human heart, which is of clinical and physiological interest. READ MORE

  4. 2. Internet Access and QoS in Ad Hoc Networks

    Author : Ali Hamidian; Lunds universitet; []
    Keywords : ad hoc networks; QoS; IEEE 802.11e; MANET; ad hoc routing; distributed resource reservation; Wireless computer communication; IEEE 802.11; ad hoc; mobile ad hoc networks; EDCA; AODV; distributed QoS;

    Abstract : It is likely that the increased popularity of wireless local area networks (WLANs) together with the continuous technological advances in wireless communication, also increase the interest for ad hoc networks. An ad hoc network is a wireless, autonomous, infrastructure-less network composed of stations that communicate with each other directly in a peer-to-peer fashion. READ MORE

  7. 5. Zero and Multi-Dimensional Modeling of Internal Combustion Engines with respect to Ion Current and Soot Formation

    Author : Abdelhadi Ahmedi; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine knock; pollutant emissions; detailed chemical kinetics; thermal ionization.; ion current sensor; method of moments; ionization; soot formation oxidation; modeling; auto-ignition; Spark ignition engine; diesel engine;

    Abstract : The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. READ MORE
