  1. 1. Crowd evacuation in high-density scenarios

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Ines Cilenti; [2019]
    Keywords : Crowd evacuation; high-density; crowd pressure; video analysis; bottleneck; outdoor event; local density.; Technology and Engineering;

    Abstract : Nowadays, is becoming increasingly frequent holding events in outdoor environments, involving a large number of people, even though these spaces were not designed from a safe prospective, in the way that safety is defined today. In such events, high density conditions is an ongoing issue, as the evacuation becomes very complex, due to the space design and the interaction among the pedestrians. READ MORE

  2. 2. Tungmetaller i dagvattendammar : en jämförelse mellan beräknade och uppmätta årsmedelhalter i inkommande dagvatten

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Mathias Andersson; [2019]
    Keywords : Germans formel; StormTac; flödesproportionell vattenprovtagning; tungmetaller; dagvatten;

    Abstract : Dagvatten som rinner längs hårdgjorda ytor i stadsmiljöer kan föra med sig tungmetaller och andra föroreningar från ytorna. Vanligtvis transporteras det förorenade dagvattnet via led- ningsnäten till en recipient där det riskerar att förorena sjöar och vattendrag. READ MORE

  3. 3. The influence of storm movement and temporal variability of rainfall on urban pluvial flooding : 1D-2D modelling with empirical hyetographs and CDS-rain

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

    Author : Jimmy Olsson; [2019]
    Keywords : pluvial flooding; flood modelling; 1D-2D modelling; MIKE FLOOD; MIKE 21; MIKE URBAN; storm movement; temporal variability; hyetograph; design storm; Chicago Design Storm; CDS-rain; pluviala översvämningar; översvämningsmodellering; 1D-2D modellering; MIKE FLOOD; MIKE 21; MIKE URBAN; molnrörelse; hyetograf; typregn; Chicago Design Storm; CDS-regn;

    Abstract : Pluvial floods are formed directly from surface runoff after extreme rain events. Urban areas are prone to suffer from these floods due to large portions of hardened surfaces and limited capacity in the stormwater infrastructure. Previous research has shown that catchment response is influenced by the spatio-temporal behaviour of the rainstorm. READ MORE

  4. 4. Detection and removal of wind turbine ice : Method review and a CFD simulation test

    University essay from Högskolan i Gävle/Energisystem

    Author : Ismael Bravo Jimenez; [2018]
    Keywords : renewable energy; wind turbine; ice accretion; flow simulation; CFD; wind turbine performance; anti-icing methods; de-icing methods.;

    Abstract : Nowadays, the energy sector is facing a huge demand that needs to be covered. Wind energy is one of the most promising energy resources as it is free from pollution, clean and probably will arise as one of the main energy sources to prevent global warming from happening. Almost 10% of the global energy demand is coming from renewable resources. READ MORE

  5. 5. Identification and evaluation of internal leakages of a BFB Boiler integrated within a pulp and paper mill.

    University essay from Högskolan i Gävle/Energisystem

    Author : Adrian Gomez; [2018]
    Keywords : leakages; internal leakages; Pulp and Paper; valves; boiler;

    Abstract : Alternative fuels like biomass have become really popular in the last decades as a substitute to fossil fuels. One of the most used technologies in Sweden for the obtention of the energy from the biomass is its direct combustion in a boiler. READ MORE
