  1. 1. Wind Turbine Recovery Forecasting using Survival Analysis

    University essay from Lunds universitet/Matematisk statistik

    Author : Anton Palets; [2023]
    Keywords : Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

    Abstract : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

  3. 2. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

    University essay from Lunds universitet/Teknisk geologi

    Author : Simon Kreipl; [2021]
    Keywords : Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

    Abstract : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. READ MORE

  4. 3. Tick data clustering analysis establishing support and resistance levels of the EUR-USD exchange market

    University essay from Lunds universitet/Matematisk statistik

    Author : Karl Tengelin; [2020]
    Keywords : Tick data; Support-and resistance levels; Clustering methods; Gaussian mixture model; Kmeans; EUR-USD exchange rates; Clustering performance metrics; Market activity; Mathematics and Statistics;

    Abstract : Our aim is to use clustering algorithms in order to compute support and resistance levels within an intra-day trading setting. To achieve this we use a tick data set from the EUR-USD exchange market during 2019 as a measure of market activity. READ MORE

  5. 4. Charge transport in a Hubbard-Holstein junction: Preliminary results from a DFT approach.

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

    Author : Eric Ceccarelli; [2019]
    Keywords : Density functional theory; DFT; Hubbard-Holstein; Hubbard-Holstein model; HH; Quantum transport; Physics and Astronomy;

    Abstract : Many-body systems are extremely complicated to describe due to mutual interactions between the constituent particles. This is for example the case of systems with electron-electron (e-e) and electron-phonon (e-ph) interactions. READ MORE

  6. 5. Using geographical information systems in epidemiology : mapping & analyzing occurrence of diarrhea in urban–residential area of Islamabad, Pakistan

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Mirza Amir Liaquat Baig; [2017]
    Keywords : Islamabad; hotspots; GIS; geographic information system; disease; cluster; diarrhea; mapping; Pakistan; Earth and Environmental Sciences;

    Abstract : Almost 2 million people are living in Islamabad, significant number of workforce commute from neighboring areas and other parts of the country. The city is facing restraint on natural resources due to increased urban migration coupled with rapid population growth. READ MORE
