  1. 1. Modelling Micropollutant Removal Through Ozonation in Wastewater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maximiliano Andrés Oportus Foster; [2023]
    Keywords : Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

    Abstract : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. READ MORE

  3. 2. Intrusion Detection systems : A comparison in configuration and implementation between OSSEC and Snort

    University essay from Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Author : Peter Stegeby; [2023]
    Keywords : Intrusion detection; HIDS; NIDS; Signature-based; Linux; Windows; Sniffing packets; Upptäcka intrång; HIDS; NIDS; Signatur-baserad; Linux; Windows; Paketsniffing.;

    Abstract : Hackare fortsätter att bli bättre på att få otillåten tillgång till våra datorer och kan undvika de mest grundläggande intrångsskyddade system och brandväggar på en standarddator. Då numren av intrång växer varje år och kostar företag miljoner av dollar, så verkar gapet mellan attackerare och försvarare att bli större. READ MORE

  4. 3. Characterization of Bi-incorporated InSb(111)A/B Surfaces : An STM and XPS Study

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

    Author : Shengpeng Huang; [2023]
    Keywords : indium antimonide; surface reconstructions; bismuth deposition; scanning tunneling microscopy; X-ray photoelectron spectroscopy.; Physics and Astronomy;

    Abstract : In recent years, III-V semiconductor materials have received increasing attention due to their admirable electronic properties like direct tunable bandgaps and high charge carrier mobility. Indium Antimonide (InSb) possesses the largest electron mobility among III-V materials and is promising for infrared detectors, high-speed field effect transistors, and spintronics. READ MORE

  5. 4. Mathematical modeling and analysis of hot carrier solar cells

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Benjamin van Dijk; [2023]
    Keywords : solar cell; nanowires; hot carrier; nanowire; analysis; mathematical model; trends; fermi function; reservoirs; Physics and Astronomy;

    Abstract : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. READ MORE

  6. 5. Optimizing L2-regularization for Binary Classification Tasks

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Oskar Bolinder; [2022]
    Keywords : Machine learning; Overtraining; L2-regularization; Model selection; Binary classification; Physics and Astronomy;

    Abstract : An Artificial Neural Network (ANN) is a type of machine learning algorithm with widespread usage. When training an ANN, there is a risk that it gets overtrained and cannot solve the task for new data. Methods to prevent this, such as L2-regularization, introduce hyperparameters that are time-consuming to optimize. READ MORE
