  1. 1. Freestanding graphite cathode with graphene additive for aluminum dual-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Adam Rosvall; [2023]
    Keywords : Aluminum ion batteries; Dual-ion batteries; Graphite; Graphene; Ionic liquid; Phase inversion method;

    Abstract : In today’s fast adjustment to renewable energy, new battery technologies are needed to meetthe ever-growing demands of energy storage. Cheaper and easier to produce materials areneeded, as well as materials with a lower environmental impact. READ MORE

  3. 2. Study of different methodologies to determine relative dielectric constant of given substrate using fabrication, modelling and measurement strategies

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anders Lundberg; [2021]
    Keywords : Relative dielectric constant; relative permittivity; PCB substrate material;

    Abstract : In this thesis, different methods for measuring the relative dielectric constant is investigated using simulations and experimental approaches. The first method is known as the S-parameter inversion method. In this method formulae is used to calculate the characteristic impedance of the microstrip line from measured S-parameters. READ MORE

  4. 3. Machine Unlearning and hyperparameters optimization in Gaussian Process regression

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

    Author : Matthis Manthe; [2021]
    Keywords : GDPR; Machine Unlearning; Data removal; Gaussian Process Regression; Product-of-Experts.; RGPD; Désapprentissage; Suppression de données; Gaussian Process regression; Product-of-Experts.; DSF; avlärningen; dataraderingen; Gaussian Process regression; Produkt-av-experter.;

    Abstract : The establishment of the General Data Protection Regulation (GDPR) in Europe in 2018, including the "Right to be Forgotten" poses important questions about the necessity of efficient data deletion techniques for trained Machine Learning models to completely enforce this right, since retraining from scratch such models whenever a data point must be deleted seems impractical. We tackle such a problem for Gaussian Process Regression and define in this paper an efficient exact unlearning technique for Gaussian Process Regression which completely include the optimization of the hyperparameters of the kernel function.

  5. 4. Interpretation of geophysical and geochemical data in a 3D geological model construction of a contaminated site

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Haoyu Wei; [2018]
    Keywords : Halogenated hydrocarbon; Geophysics; DCIP; GeoScene3D; Groundwater chemistry; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : The Alingsås dry-cleaning facility is one of the heavily halogenated hydrocarbon contaminated sites in Sweden. The source of contamination dates back to the 1970s when a large scale tetrachloroethylene leakage outbroke inside the dry-cleaning building. READ MORE

  6. 5. GPU Usage for Parallel Functions and Contacts in Modelica

    University essay from Lunds universitet/Institutionen för datavetenskap

    Author : Vilhelm Roxling; Axel Goteman; [2015]
    Keywords : Arbitrary Shapes; Collision Response; Auto-generation; Collision Detection; Modelica; GPU; Technology and Engineering;

    Abstract : This thesis investigates two ways of incorporating GPUs in Modelica. The first by automatically generating GPU code for Modelica functions, and the second by using GPU accelerated external code for a contact handling package. Automatic parallelization of functions is desired, as it can potentially accelerate large simulations significantly. READ MORE
