  1. 1. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aleksandra Ivanova; [2019]
    Keywords : physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

    Abstract : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. READ MORE

  2. 2. Optimization and Control of Heat Loads in Buildings

    University essay from KTH/Energiteknik

    Author : Matilda Stendahl; [2018]
    Keywords : district heating; peak shaving; capacity control; smart heating; demand side management; fjärrvärme; toppkapning; effektstyrning; värmestyrning; efterfrågesidahantering;

    Abstract : District heating is considered an environmentally friendly, efficient and cost-effective way of providingheat to buildings but even so, the industry will be facing several challenges in the upcoming years. Acombination of higher operating costs, growing demand, competition from alternative heatingtechnologies, national and international climate and energy goals and the need for transparency towardscustomers places high requirements on many thermal energy suppliers.

  3. 3. Greehouse Gas Simulations in Munich : Investigation of Wind Averaging Techniques for analysis of column measurements (XCO2) using CFD

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Diptesh Pawa; [2018]
    Keywords : CFD; RANS; OpenFOAM; SIMPLE; greenhouse gas emissions; wind averaging techniques;

    Abstract : The underlying objective of this thesis was to perform GHG simulation studies to predict the dispersion and transport of greenhouse gases emitted from a thermal power plant in order to assess the extent of dangerous living environment for those surrounding it in case of an unforeseen calamity. The research carried out during this thesis was to investigate the method of wind averaging techniques to analyse column measurements (XCO2). READ MORE

  4. 4. Estimation of Relative Seismic Velocity Changes Around Katla Volcano, Using Coda in Ambient Seismic Noise

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Jonsdottir; [2018]
    Keywords : Katla volcano; Iceland; ambient seismic noise; coda waves; relative velocity variations; Katla vulkan; Island; omgivande seismiskt brus; codavågor; relativa hastighetsvariationer;

    Abstract : Relative seismic velocity variations in the Earth’s crust can be estimated by using ambient seismic noise records from a pair of stations. Velocity variations can be caused by stress perturbations in the subsurface. Therefore, information on stress changes in the crust can possibly be retrieved from measured velocity variations in the medium. READ MORE

  5. 5. Building integrated photovoltaic (BIPV) modelling for a demo site in Ludvika based on building information modelling (BIM) platform

    University essay from Högskolan Dalarna/Energiteknik

    Author : Samer Quintana; [2018]
    Keywords : BIPV; BIM; Solar; Energy; 3D; Modelling; Building; Information; PV;

    Abstract : This thesis aims to design and simulate a building integrated photovoltaic (BIPV) system for three demo buildings in Ludvika, Sweden, which is part of the Energy- Matching’s project under the European H2020 research scheme. A literature review was firstly conducted in the area of energy scenarios, engineering tools, methodologies and the workflows in design and building energy modelling. READ MORE
