  1. 1. Highway Traffic Forecasting with the Diffusion Model : An Image-Generation Based Approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Pengnan Chi; [2023]
    Keywords : Diffusion model; Traffic forecasting; Generative model; Image processing; Spatial temporal modelling; Diffusionsmodell; Trafikprognos; Generativ modell; Bildbehandling; Rumsligtemporal modellering;

    Abstract : Forecasting of highway traffic is a common practice for real traffic information system, and is of vital importance to traffic management and control on highways. As a typical time-series forecasting task, we want to propose a deep learning model to map the historical sensory traffic values (e.g., speed, flow) to future traffic forecasts. READ MORE

  2. 2. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Henriette Nishimwe; [2023]
    Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

  3. 3. Developing transport interaction macromodels to simulate traffic patterns : Case of Oslo, Norway

    University essay from KTH/Transportplanering

    Author : Omkar Parishwad; [2022]
    Keywords : Spatial Interaction Modelling; Transport Modelling; City Planning; OD Matrices; Trip distribution; Transport Simulations; Sustainable Development Goals;

    Abstract : Predicting the passenger flow inside a city is a vital component of the intelligent transportation management system. The proposal for a new residential area, an office space, post­pandemic policy implications for work from home, behavioral changes for revised traffic patterns, infrastructural improvements, require a visual and analytical backing which can be provided through a macro simulation model.

  4. 4. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Oskar Evert Johansson; [2021]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE

  5. 5. A detailed study on Amazon Forest structure and mortality rates through LPJ-GUESS vegetation model

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sara Mazzuoli; [2021]
    Keywords : Amazon s Forest; LPJ-GUESS; simulation; TEAM-NETWORK; dynamic vegetation model; observation; mortality; allometry; tree stand structure; biomass; cohort; PFTs; plant functional types; NPP; Earth and Environmental Sciences;

    Abstract : Nowadays it has become relevant for scientists to understand the impact of tropical forest structure on the Global Carbon Cycle. Dynamic vegetation models have been developed to pursue this issue, specifically by improving algorithms that could analyze the allometry, biomass content and mortality rate of each singular simulated plant individual and how this responds to climate change, management and rising CO2 concentrations.
