  1. 1. Development of a Nordic BWR plant model in APROS and design of a power controller using the control rods

    University essay from KTH/Fysik

    Author : Jonathan Al-Ani; [2021]
    Keywords : APROS; Dynamic process simulation; System code; Nuclear reactor; nuclear power; BWR; Boiling Water Reactor; closed cycle; steam cycle; one-dimensional flow; Westinghouse; control rods; APROS; Dynamisk processimulering; Beräkningsmodell; Kärnkraft; BWR; Kokvattenreaktor; ångcykel; en-dimensionell flödesmodell; Westinghouse; kontrollstavar;

    Abstract : In this master thesis an input-model of a Nordic BWR power plant has been developed in APROS. The plant model contains key systems and major thermohydraulic components of the steam cycle, including I&C systems (i.e. power, pressure, level and flow controls). READ MORE

  2. 2. Design and implementation of embedded system for chl-a fluorescence detection

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

    Author : Anargyros Katsogridakis; [2021]
    Keywords : Embedded systems; Microcontrollers; Harmful algal bloom; Climate change; chl-a fluorescence; Inbyggda system; mikrokontroller; skadlig algblomning; klimatförändring; chl-a-fluorescens;

    Abstract : Over the last decades, the effects of climate change have become increasingly evident across natural environments. Apart from other areas, climate change poses a serious threat on water quality. READ MORE

  3. 3. Water-related disasters : An overview of landslides and floods in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Josefin Wiklund Klingbjer; [2021]
    Keywords : Natural disasters; floods; flooding; landslide; ArcGIS; Sweden; Västra Götaland; Västernorrland; Värmland; Västerbotten; Örebro; Ångermanälven; Norsälven; Klarälven; Göta älv; Naturkatastrofer; översvämning; skred; ArcGIS; Sverige; Västra Götaland; Västernorrland; Värmland; Västerbotten; Örebro; Ångermanälven; Norsälven; Klarälven; Göta älv;

    Abstract : Current research shows that water-related disasters are the most common natural disaster worldwide and these disasters are increasing in numbers. Water-related disasters cause negative consequences through damage to infrastructure and human health. READ MORE

  4. 4. How design storms with normally distributed intensities customized from precipitation radar data in Sweden affect the modeled hydraulic response to extreme rainfalls

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära; Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Daniel Elfström; Max Stefansson; [2021]
    Keywords : cloudbursts; cloudburst mapping; spatial rain variation; pluvial flooding; hydraulic response; Swedish precipitation radar data; idealized urban catchment; hydrodynamic modeling; skyfall; skyfallskartering; gaussisk regnfördelning; spatial regnvariation; pluvial översvämning; hydraulisk respons; svensk nederbördsradardata; idealiserat urbant avrinningsområde; hydrodynamisk modellering;

    Abstract : Intense but short-term cloudbursts may cause severe flooding in urban areas. Such short-term cloudbursts mostly are of convective character, where the rain intensity may vary considerably within relatively small areas. Using uniform design rains where maximum intensity is assumed over the whole catchment is common practice in Sweden, though. READ MORE

  5. 5. CONCEPTUAL DEVELOPMENT OFWATERLESS TOILET

    University essay from Jönköping University/JTH, Industridesign

    Author : Fredrik Lorén; [2021]
    Keywords : Waterless toilet; Product development; design; Industrial design; Concept; Flat packaging;

    Abstract : Poverty is a real problem in many countries. These countries need extra support to get their lives back to a sanitary way of living again. Together with the organization X-Runner and Separett, the people of Peru get access to sanitation solutions such as toilets without profit. READ MORE
