  1. 1. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

    University essay from KTH/Materialvetenskap

    Author : Atharva Kotasthane; [2023]
    Keywords : Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

    Abstract : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. READ MORE

  3. 2. Predicting the threshold grade for university admission through Machine Learning Classification Models

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anas Almawed; Anton Victorin; [2023]
    Keywords : Admission data; Data Classification; Machine Learning; Logistic Regression; Support Vector Machine; Decision Tree Classifier; Random Forest; Antagningsdata; Dataklassificering; Maskininlärning; Logistic Regression; Support Vector Machine; Decision Tree Classifier; Random Forest;

    Abstract : Higher-level education is very important these days, which can create very high thresholds for admission on popular programs on certain universities. In order to know what grade will be needed to be admitted to a program, a student can look at the threshold from previous years. READ MORE

  4. 3. “We Were Called Low-Grades” : Current Archival Approaches to the Digitization and Dissemination of Eugenics Collections

    University essay from Uppsala universitet/Institutionen för ABM

    Author : Georgia Gilbert Gladitz; [2022]
    Keywords : Digitization; Eugenics Collections; Access and Care; Digital Knowledge Dissemination; Difficult Histories; Archival Methodologies; Statens institut för rasbiologi; The Wellcome Library; The Image Archive on the American Eugenics Movement; The Canadian Eugenics Archive;

    Abstract : This thesis examines the current methodological approaches to digital access and dissemination of eugenics archives. It looks in-depth at four institutions from around the world which provide some means of digital access to a specific eugenics collection that they control: the Wellcome Collection within the Wellcome Library in London, the Image Archive on the American Eugenics Movement founded in part by the Cold Springs Laboratory in New York, the Canadian Eugenics Archive, and the State Institute for Race Biology at the Uppsala University Library Special Collections in Sweden.

  5. 4. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  6. 5. Evaluation of factors that might affect the grading of heart murmurs in dogs with myxomatous mitral valve disease

    University essay from SLU/Dept. of Clinical Sciences

    Author : Emilia Horn; [2022]
    Keywords : murmur grading; grading of heart murmurs; factors impacting murmur grading; utility of murmur grading scales; myxomatous mitral valve disease; MMVD; dog;

    Abstract : Myxomatous mitral valve disease (MMVD) is the most common heart disease in dogs. The first sign of MMVD is usually a heart murmur, which most commonly is detected before clinical signs of the disease potentially develop. The preclinical period of MMVD is usually long and can be prolonged with medical treatment. READ MORE
