  2. 16. 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

  4. 17. Real-time control of an SI engine using ion current based algorithms

    Author : Stefan Byttner; Jean-Pierre Robert Haphout; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal Combustion Engines; Neural Networks; Ion Current;

    Abstract : Reducing emissions and improving fuel efficiency in automobiles are today important issues. New sensor techniques are developed to extract detailed combustion information to enable closed loop engine control. READ MORE

  5. 18. Molecular aspects on voltage-sensor movement

    Author : Amir Broomand; Fredrik Elinder; Guiscard Seebohm; Linköpings universitet; []
    Keywords : Potassium channels; voltage-gated; chemistry; metabolism; physiology; patch-clamp techniques; oocytes; MEDICINE; MEDICIN;

    Abstract : Voltage-gated ion channels are fundamental for electrical signaling in living cells. They are composed of four subunits, each holding six transmembrane helices, S1-S6. Each subunit contains a voltage-sensor domain, S1-S4, and a pore domain, S5-S6. READ MORE

  6. 19. Mathematical Modelling of Cerebral Metabolism : From Ion Channels to Metabolic Fluxes

    Author : Nicolas Sundqvist; Gunnar Cedersund; Maria Engström; Roland Nilsson; Sebastian Sten; João Duarte; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The brain is the most metabolically active organ in the human body and therefore rely on a continuous supply of oxygen and glucose. Neuronal stimulation in specific regions of the leads to the firing of action potentials, a process facilitated by voltage-gated ion channels in the neurons’ cell membranes. READ MORE

  7. 20. Controlling ion transport in organic devices

    Author : Xiaodong Wang; Magnus Berggren; Xavier Crispin; Linköpings universitet; []
    Keywords : ;

    Abstract : Organic electronics and printed electronics have been attracting more and more research interest in the past decades. Polymers constitute an important class of materials within the field organic electronics due to their unique physical and chemical properties. READ MORE
