Homogeneous Charge Compression Ignition (HCCI) combustion lacksdirect ignition timing control, instead the auto ignition depends on the operatingcondition. Since auto ignition of a homogeneous mixture is very sensitive tooperating condition a fast combustion timing control is necessary for reliableoperation, the ignition timing control design requiring appropriate modelsand system output variables

Popular Abstract in Swedish I denna avhandling har morfologin och kristallstrukturen av epitaxiellt växta nanotrådstrukturer undersökts med hjälp av svepelektronmikroskopi (SEM), transmissionselektronmikroskopi (TEM) och multi-slice (MS) simuleringar. Bland annat har vi funnit att de lamellära tvillingar som ofta observeras i III-V nanotrådar växta i <111>B riktningarna tenderar att begränsas av eIn this work, the morphology and crystal structure of epitaxial semiconductor nanowire structures grown by metal-organic vapour phase epitaxy (MOVPE) are studied by electron microscopy methods. In particular, the three-dimensional structure of nanowires and nanotrees has been characterised by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM) and multi-sli
Effects of the intrinsic electron spin-orbit interaction on transport and optical properties of III-V semiconductor quantum wells have been studied theoretically. It is shown that due to crystal anisotropy of this interaction, the weak localization magnetoresistance in a magnetic field parallel to interfaces is very sensitive to the epitaxy growth direction and also to the orientation of the magn
The problem addressed in this thesis is how to account for environmental aspects when purchasing freight transports. This problem is addressed from a transport purchasing perspective. The result of the research is a model for how transport purchasers can incorporate environmental aspects when purchasing freight transports. This mode! is built on two tools and a work process. The first too! is a st
Gothika breaks new ground in forensic psychology by implying a new defense: innocent by reason of spirit possession. The film, on its surface, deals with a number of other psychological issues. Its heroine, Dr. Miranda Gray, is a criminal psychologist who works in an institution for the criminally insane. There is discussion of repression as a "survival tool," episodes of apparent psychogenic amne
The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to
Ett antologikapitel som behandlar hur man definiererar, identifierar och kvalificerar kunskapsutveckling i historia utifrån frågorna varför det är bra att läsa historia och vad en historiker kan som inte andra kan.

Recently there has been a resurgence of intense experimental and theoretical interest on the Kondo physics of nanoscopic and mesoscopic systems due to the possibility of making experiments in extremely small samples. We have carried out exact diagonalization calculations to study the effect of the energy spacing Delta of the conduction band on the ground-state properties of a dense Anderson model
