  1. 6. Spatial modeling with INLA for analysis of unequal care in Skåne

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Julia Wierzchoslawska; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The objective of this thesis is to extend on a previous analysis of health care accessibility for patients diagnosed with a chronic disease in Region Skåne. The previous analysis resulted in a logistic mixed effects model having municipality as a random effect and age as a first-degree spline-function. LÄS MER

  3. 7. Moving in the dark : Mathematics of complex pedestrian flows

    Magister-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Meghashyam Veluvali; [2023]
    Nyckelord :Mathematical modelling of pedestrian dynamics; stochastic systems; evacuation time; random walk method; parabolic equation; finite difference method;

    Sammanfattning : The field of mathematical modelling for pedestrian dynamics has attracted significant scientific attention, with various models proposed from perspectives such as kinetic theory, statistical mechanics, game theory and partial differential equations. Often such investigations are seen as being a part of a new branch of study in the domain of applied physics, called sociophysics. LÄS MER

  4. 8. Forecasting monthly LME Copper returns

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Nils Lervik; Philip Thorsell; [2022-06-29]
    Nyckelord :;

    Sammanfattning : We evaluate if monthly LOCADY returns on the London Metal Exchange can be accurately predicted one, two and three months ahead. In total ten models are constructed using time-varying parameters and bandwidth optimization. LÄS MER

  5. 9. Grid-based Energy Aware Mobility Model for FANETs

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Mohammad Messbah Uddin; [2022]
    Nyckelord :FANET; Clustering algorithm; Unmanned Aerial Vehicle UAV ; Grid-based clustering; Mobility model; energy consumption; sustainability;

    Sammanfattning : Drones flying in squad formation while interconnected in an ad-hoc fashion are called Flying Ad hoc Networks (FANETs). These FANETs are gathering special interests in the networking community in their deployment for different vital missions. LÄS MER

  7. 10. A comparative analysis on the predictive performance of LSTM and SVR on Bitcoin closing prices.

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Hakim Rayyan; [2022]
    Nyckelord :Long Short-Term Memory LSTM ; Support Vector Regression SVR ; Random Walk; Bitcoin;

    Sammanfattning : Bitcoin has since its inception in 2009 seen its market capitalisation rise to a staggering 846 billion US Dollars making it the world’s leading cryptocurrency. This has attracted financial analysts as well as researchers to experiment with different models with the aim of developing one capable of predicting Bitcoin closing prices. LÄS MER
