  2. 1. Incremental Clustering of Source Code : a Machine Learning Approach

    Author : Tobias Olsson; Morgan Ericsson; Sebastian Herold; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machine Learning; Naive Bayes; Source Code Clustering; Incremental Clustering; Software Architecture; Technical Debt; Computer Science; Datavetenskap;

    Abstract : Technical debt at the architectural level is a severe threat to software development projects. Uncontrolled technical debt that is allowed to accumulate will undoubtedly hinder speedy development and maintenance, introduce bugs and problems in the software product, and may ultimately result in the abandonment of the source code.

  4. 2. Analysis of Deformation of Gas Diffusion Layers and the Impact on Performance of PEM Fuel Cells

    Author : Jiatang Wang; Värmeöverföring; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PEM fuel cell; compression ratio; assembly pressure; porosity; deformed GDL; electric resistance; transport phenomena; model; performance; analysis; OpenFOAM;

    Abstract : Proton exchange membrane (PEM) fuel cells have been promoted due to significant breakthroughs in various aspects and increasing public interests. The porous features of the gas diffusion layer (GDL) and the necessary assembly processes generate localized pressure forces on the channel/shoulder structure of the bi-polar plates (BPP). READ MORE

  5. 3. Degradation Pathways of Dimethylmercury in Natural Waters

    Author : Johannes West; Sofi Jonsson; Andrew Graham; Elena Gorokhova; Bridget Bergquist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mercury; Marine; Degradation; Methylmercury; Aquatic; Environmental Sciences; miljövetenskap;

    Abstract : Mercury (Hg) is a naturally occurring toxic trace metal whose release into the environment has been (and still is) exacerbated by human activities. The bioavailability of Hg is tied to its chemical speciation, with monomethylmercury (MMHg) being the primary form of Hg that bioaccumulates and biomagnifies. READ MORE

  6. 4. Source Code Representations of Deep Learning for Program Repair

    Author : Zimin Chen; Martin Monperrus; Benoit Baudry; Zhendong Su; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Code Representation; Deep Learning; Program Repair; Datalogi; Computer Science;

    Abstract : Deep learning, leveraging artificial neural networks, has demonstrated significant capabilities in understanding intricate patterns within data. In recent years, its prowess has been extended to the vast domain of source code, where it aids in diverse software engineering tasks such as program repair, code summarization, and vulnerability detection.

  7. 5. Chemical characteristics of atmospheric aerosols : the influence of natural and man-made sources and sinks

    Author : Michael Norman; Jost Heintzenberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meteorology; Meteorologi; meteorologi; Meteorology;

    Abstract : In order to improve the understanding of the climatic and environmental effects of atmospheric aerosol particles, knowledge about their sources, sinks, chemical and physical characteristics as well as transportation in the atmosphere is needed. This thesis examines the water-soluble chemical characteristics of aerosol particles and precipitation and their interaction with trace gases. READ MORE
