  1. 1. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions

    University dissertation from Department of Energy Sciences, Lund University

    Author : Sam Shamun; Lunds universitet.; Lund University.; [2019-01-25]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Ethanol; Oxygenated Fuel Blends; Compression Ignition Engine; Partially Premixed Combustion; Combustion Characteristics; Efficiency; Emissions; Particulate Matter; Metanol; Etanl; Oxygenerade Bränsleblandningar; Kompressionsantänd Motor; Partiellt Förblandad Förbränning; Förbränningsegenskaper; Verkningsgrad; Emissioner; Partiklar;

    Abstract : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. READ MORE

  2. 2. Seepage monitoring in embankment dams

    University dissertation from Institutionen för anläggning och miljö

    Author : Sam Johansson; KTH.; [1997]
    Keywords : ;

    Abstract : Internal erosion, which is one of the major reasons forembankment dam failure, causes an increased seepage flow due toloss of fines. A seepage measuring system is therefore a vitalpart of an embankment dam’s monitoring system. Manyexisting seepage monitoring systems are not however sensitiveenough to detect small changes in the seepage flow. READ MORE

  3. 3. Imaging and Treatment Outcome of Potentially Curable Prostate Cancer

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sam Ladjevardi; Uppsala universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The over-all aim of the present study was to compare the results of treatment with curative intent, with conservative treatment in men with prostate cancer (PCa) without distant metastases.In a population-based cohort in Sweden, the predictive value of prostate-specific antigen (PSA) was evaluated and the relative survival of men considered plausible candidates for treatment with curative intent was investigated.

  4. 4. Holomorphic embeddings and applications

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Sam Lodin; Mittuniversitetet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anders´en-Lempert-theory; holomorphic embeddings; Eisenman hyperbolicity; holomorphic group actions; plurisubharmonic extension; analytic polyhedron; MATHEMATICS; MATEMATIK;

    Abstract : In the first part of this thesis we consider the question of the number of equivalenceclasses of holomorphic embeddings of Ck into Cn. We show the existence of holomorphicfamilies of proper holomorphic embeddings of Ck into Cn (0 < k < n?1),such that members of the family are pairwise nonequivalent in a suitable sense. READ MORE
