  1. 16. 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

  3. 17. 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

  4. 18. 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

  5. 19. 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

  7. 20. Exchange Rate Risk and Forecasting

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Ian Wallgren; [2022]
    Nyckelord :Exchange rate risk; exchange rate forecasting; Autoregressive Integrated Moving Average ARIMA ; Uncovered Interest Rate Parity UIRP ; Business and Economics;

    Sammanfattning : Since the collapse of the Bretton Woods system, the system of fixed exchange rates amongst principal industrial countries, in the early 1970s, a new era began, introducing the floating exchange rate regime. Since the inception of the floating rate regime, the general interest in forecasting exchange rate movements has grown considerably. LÄS MER
