  1. 1. A study of surface temperature and heat flux estimations in heating processes by solving an Inverse Heat Conduction Problem

    Author : Patrik Wikström; Wlodzmierz Blasiak; Björn Palm; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The topic of this thesis is estimation of the dynamic changes of the surface temperatureand heat flux during heating processes by using an inverse method. The local transient surface temperature and heat flux of a steel slab are calculated based on measurements in the interior of the slab. READ MORE

  2. 2. Some aspects of cryptographic protocols : with applications in electronic voting and digital watermarking

    Author : Björn Terelius; Douglas Wikström; Helger Lipmaa; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Cryptographic protocols are widely used on the internet, from relatively simple tasks such as key-agreement and authentication to much more complex problems like digital cash and electronic voting. Electronic voting in particular is a problem we investigate in this thesis. READ MORE

  3. 3. Identification of miRNA expression profiles for diagnosis and prognosis of prostate cancer

    Author : Jessica Carlsson; Karin Klinga Levan; Björn Olsson; Gisela Helenius; Pernilla Wikström; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; microRNAs; prostate zones; normalization; endogenous controls; Medicin; Medicine;

    Abstract : Cancer of the prostate (CaP) is the most common malignancy diagnosed in men in the Western society. During the last years, prostate specific antigen (PSA) has been used as a biomarker for CaP, although a high PSA value is not specific for CaP. Thus, there is an urgent need for new and improved diagnostic markers for CaP. READ MORE

  4. 4. Effects of Hemoglobin Normalization with Epoetin in Chronic Kidney Disease

    Author : Hans Furuland; Björn Wikström; Torbjörn Linde; Peter Barany; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Internal medicine; Anemia; blood viscosity; cardiac output; chronic kidney disease; renal dialysis; dialysis adequacy; erythopoietin; heart rate variability; hemoglobin; hemorheology; hypertension; kidney transplantation; Kt V; left ventricular hypertrophy; Quality of Life; Invärtesmedicin; Internal medicine; Invärtesmedicin;

    Abstract : Anemia is common in patients with chronic kidney disease (CDK), contributes to reduced Quality of Life (QoL) and is associated with cardiovascular disease, morbidity and mortality. Epoetin raises hemoglobin (Hb) and increases QoL and physical exercise capacity. READ MORE

  5. 5. Assessment of Atherosclerosis by Whole-Body Magnetic Resonance Angiography

    Author : Tomas Hansen; Håkan Ahlström; Lars Lind; Johan Wikström; Lars Johansson; Björn Fagerberg; Uppsala universitet; []
    Keywords : Radiology; Atherosclerosis; Magnetic Resonance Angiography; Epidemiology; Radiologisk forskning;

    Abstract : Atherosclerosis is a serious threat to public health and a major cause of morbidity and mortality. In this doctoral research, the feasibility of using whole-body magnetic resonance angiography (WBMRA) was studied as a principal aim both in patients and in an epidemiological setting. READ MORE
