  1. 1. Uncertainty quantification for offshore wind turbines

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Ziming Wang; [2022]
    Nyckelord :wind energy; uncertainty propagation; polynomial chaos; Rosenblatt transformation; quadrature; regression; vindenergi; osäkerhetsutbredning; polynomkaos; Rosenblatt transformation; kvadratur; regression;

    Sammanfattning : Wind energy is a field with a large number of uncertainties. The random nature of the weather conditions, including wind speed, wind direction, and turbulence intensity, influences the energy output and the structural safety of a wind farm, making its performance fluctuate and difficult to predict.

  3. 2. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Hasan Al-Zubaidi; [2022]
    Nyckelord :Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

    Sammanfattning : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). LÄS MER

  4. 3. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Nic Ekman; Ilias Theodoros Skordas; [2022]
    Nyckelord :5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Sammanfattning : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

  5. 4. Stochastic Inventory Management

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Ardit Mehmeti; [2021]
    Nyckelord :Applied Mathematics; Inventory Management;

    Sammanfattning : This bachelor thesis is about a stochastic inventory theory and how changes in different parameters affect the cost system. The inventory is based on a stochastic version of an economic quantity order (EOQ) model with planned shortages. LÄS MER

  7. 5. Stokastiska modellers framtida roll för investeringsbeslut i fastigheter

    Kandidat-uppsats, KTH/Fastigheter och byggande

    Författare :Hampus Karlsson; Emil Teimert; [2021]
    Nyckelord :Real Estate; Investment decisions; Stochastic models; Monte Carlo-Method; risk; Fastigheter; investeringsbeslut; stokastiska modeller; Monte Carlo metod; risk;

    Sammanfattning : Digitalisering, datainsamling och de kraftigt utökade databaser som idag finns tillgängliga är något som resulterat i stora förändringar i hur man arbetar, detta gäller många branscher och inte minst fastighetsbranschen. Den ökade mängden tillgängliga data är ett stort hjälpmedel när det kommet till att ta beslut. LÄS MER
