  1. 1. Optimization over nonnegative matrix polynomials

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Daniel Cederberg; [2023]
    Keywords : Proximal methods; nonnegative polynomials; Bregman proximal operator; Itakura-Saito distance; spectral estimation; functional connectivity analysis.;

    Abstract : This thesis is concerned with convex optimization problems over matrix polynomials that are constrained to be positive semidefinite on the unit circle. Problems of this form appear in signal processing and can often be solved as semidefinite programs (SDPs). READ MORE

  3. 2. Adapting Marching Squares to operate on sparse matrices

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Tahir Mert Karkan; [2022]
    Keywords : ;

    Abstract : Marching Squares is an algorithm that iterates over a given matrix filled with data points and outputs lines depending on the values in the grid. The algorithm iterates over the matrix four data points at a time in the shape of a square, hence its name. READ MORE

  4. 3. Implementation and optimization of LDPC decoding algorithms tailored for Nvidia GPUs in 5G

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Benjamin Salomonsson; [2022]
    Keywords : New Radio NR ; Shared Channel; Channel Coding; Low Density Parity-Check LDPC ; Min-Sum Algorithm MSA ; Graphics Processing Unit GPU ; Compute Unified Device Architecture CUDA ;

    Abstract : Low-Density Parity-Check (LDPC) codes are linear error-correcting codes used to establish reliable communication between units on a noisy transmission channel in mobile telecommunications. LDPC algorithms detect and recover altered or corrupted message bits using sparse parity-check matrices in order to decipher messages correctly. READ MORE

  5. 4. Representation and Efficient Computation of Sparse Matrix for Neural Networks in Customized Hardware

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

    Author : Lihao Yan; [2022]
    Keywords : Convolutional neural networks; Sparse matrix representation; Model compression; Algorithm-hardware co-design; AlexNet; Konvolutionella neurala nätverk; Sparsam matrisrepresentation; Modellkomprimering; Algoritm-hårdvarusamdesign; AlexNet;

    Abstract : Deep Neural Networks are widely applied to various kinds of fields nowadays. However, hundreds of thousands of neurons in each layer result in intensive memory storage requirement and a massive number of operations, making it difficult to employ deep neural networks on mobile devices where the hardware resources are limited.

  6. 5. Modeling and simulation of chromatographic separation in Modelon Impact

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Oliver Thelander; [2022]
    Keywords : Chemical engineering; Simulering; Modellering; Kromatografi; Adsorption; Modelica; Modelon Impact; Recirkulation; Simulation; Modeling; Chromatography; Recirculation; Technology and Engineering;

    Abstract : The aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. READ MORE
