  1. 1. A C++ Matrix library for computing the Gateaux derivative of the Fermi-Dirac operator

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : William Samuelsson; [2023]
    Keywords : C ; Quantum Chemistry; Matrix functions;

    Abstract : Computing the Fermi-Dirac operator is done through recursive polynomial expansions, using the SP2 and SP2 Acc algorithms. The Gateaux derivative is computed for both schemes by mapping the zeroth and first order matrices onto a block upper triangular matrix, which is implemented in Python using Numpy arrays to store full matrices and in C++ by first constructing a basic matrix library to use as blocks in a later created block upper triangular matrix library which only directly references two blocks in a 2 x 2 block matrix.

  3. 2. Image-classification for Brain Tumor using Pre-trained Convolutional Neural Network

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

    Author : Bushra Alsabbagh; [2023]
    Keywords : Brain tumor; Deep learning; Convolutional Neural Network CNN ; diagnosis; Image classification; pre-trained models; dataset; economic impact.; Cancer; Hjärntumör; Artificiell intelligens AI ; djupinlärning; konvolutionellt neuralt nätverk CNN ; Diagnostik; Bildklassificering; förtränade modeller; dataset.;

    Abstract : Brain tumor is a disease characterized by uncontrolled growth of abnormal cells in the brain. The brain is responsible for regulating the functions of all other organs, hence, any atypical growth of cells in the brain can have severe implications for its functions. READ MORE

  4. 3. Randomized Diagonal Estimation

    University essay from KTH/Matematik (Avd.)

    Author : Niclas Joshua Popp; [2023]
    Keywords : Diagonal estimation; randomized numerical linear algebra; low-rank approximation; matrix functions; Diagonalestimering; randomiserad numerisk linjär algebra; lågrankad approximation; matrisfunktioner;

    Abstract : Implicit diagonal estimation is a long-standing problem that is concerned with approximating the diagonal of a matrix that can only be accessed through matrix-vector products. It is of interest in various fields of application, such as network science, material science and machine learning. READ MORE

  5. 4. Dinner Chair for Children : A highchair to bring along and grow with - From idea to product concept

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Jana Kettunen; Ella Viberg; [2023]
    Keywords : Child; chair; product development; design methods; ergonomic;

    Abstract : The demand for well-adjusted and useable children´s products increase in conjunction with the interest of children’s environment and understanding for how their needs differ from adults. Even if the market has increased the last years an absence still can be perceived of a children’s highchair which is fit for children from six months of age till five years, and at the same time both transportable and aesthetic.

  6. 5. Grönare gata på 25 kvadrat : en studie av utmaningar och möjligheter med biodiversitetsfrämjande parklets i urban miljö

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Amanda Freng Blümke; [2023]
    Keywords : parklet design; biodiversitet; pollinatörer; innovation; taktisk urbanism; växtdesign; ekologisk hållbarhet; SPUGS; urban ekologi; ekosystemtjänster; framtidsvisioner; ruderatmarker; naturen som förebild; torktåliga arter; sociala värden;

    Abstract : Idag lever nästan 90% av Sveriges befolkning sina liv i urbana miljöer. Eftersom expansionen i många städer blivit begränsad riktas i stället blickarna mot den täta staden som lösning på problemet. Men med förtätning följer också många utmaningar. READ MORE
