  1. 1. Feature Selection for Microarray Data via Stochastic Approximation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Erik Rosvall; [2024-03-18]
    Keywords : feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

    Abstract : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. READ MORE

  3. 2. 2D Reflection Seismic Imaging of Rødby Structures, Denmark: Geological Conditions for CO2 Sequestration

    University essay from Uppsala universitet/Geofysik

    Author : Mussie Habtemariam Zeru; [2024]
    Keywords : Reflection seismic; Geologic carbon storage; Sandstone; Structures; Rødby;

    Abstract : Amidst the global climate action movement, geologic carbon storage (GCS) has emerged as a pivotal strategy for mitigating atmospheric CO2 levels, offering environmental and economic opportunities. This thesis targets the Bunter Sandstone Formation within the Rødby structures in Denmark, focusing on seismic Profile 1.

    Keywords : Time series analysis; Navigation system; Underground mines; Post-analysis;

    Abstract : This project aims to develop a simulator for generating realistic data from vehicles operating in underground mines, encompassing positional data and sensor values of the velocity and angle. The project addresses the challenge of analyzing the Hybrid Positioning algorithm within Mobilaris Onboard, a navigation system for underground mines. READ MORE

  5. 4. En god djurvälfärd? : en litteraturstudie om vad som kan göras för att minska mjölkkors rädsla i samband med lastning och transport

    University essay from SLU/Institutionen för tillämpad husdjursvetenskap och välfärd

    Author : Cecilia Ansin; [2024]
    Keywords : Mjölkkor; rädsla; stress; lastning; transport; förebygga;

    Abstract : Rädda och stressade djur är inte välmående djur. Rädda mjölkkor kan reagera oförutsägbart och hastigt vilket gör att de kan vara farliga att hantera. Rädsla och stress hos mjölkkor kan orsaka fysiska skador, materiella skador och ekonomiska förluster. READ MORE

  6. 5. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE
