  1. 1. Experimental investigation of ventilation performance of corner placed stratum ventilation in an office environment

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Gasper Choonya; [2019]
    Keywords : Stratum ventilation; local air change index; air change efficiency; ventilation effectiveness; draught rate; percentage dissatisfied; heat removal effectiveness;

    Abstract : Energy use in buildings account for about one third of the total global energy supply and contributes as much as 30% of the anthropogenic greenhouse gas emissions. It is estimated that energy use in buildings will increase to 67% by 2030. READ MORE

  3. 2. Hydrology of the karstic basin of Sprimont, Belgium : On the use of spectrofluorimetry and pharmaceutical substances as a supporting tool for hydrochemistry analysis

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Romain Deleu; [2018]
    Keywords : hydrology; hydrogeology; karst; karstic; spectrofluorimetry; pharmaceutical; hydrochemistry; spring; losing stream; self-organizing map; SOM; Belgium; aquifer; undergound; stream; nitrogen; carbon; isotopes; contamination; risk; human impact; sewage; wastewater; tracer;

    Abstract : The strong variation in carbonate content of the geological formations in the basin of Sprimont, Belgium, implies different groundwater behaviours in the substratum. The existence of carbonated materials such as limestone is responsible for the existence of a well-developed karstic system restricted to the Carboniferous materials which has a strong impact on the local hydrology and hydrogeology.

  4. 3. Assessing the Improvements GAIA-DR1 Will Bring to Dynamical Astronomy

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Mateo Prgomet; [2017]
    Keywords : Physics and Astronomy;

    Abstract : The first part of this thesis deals with the dynamical estimation of the Oort constants using proper motions and parallaxes provided from the Gaia-DR1 TGAS catalogue. The photometric information was provided by the 2MASS catalogue. READ MORE

  5. 4. Wireless wave propagation in city street canyons

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Andrés Felipe Garcia Albarracin; [2017]
    Keywords : Channel modeling; Channel sounding; Local scattering function; Ray tracing.; Technology and Engineering;

    Abstract : This project aims to determine the characteristics of a wireless communication channel in city-street-canyon scenarios. The channel of a typical city intersection is modeled with a ray tracer and measured with a channel sounder. Then, the results of both tools are compared in terms of the local scattering function.

  6. 5. Analysis of human exposure at local exhaust ventilation by means of 3D air velocity measurements, tracer gas tests and controlled turbulence environment

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Leyre Catalan Ros; [2015]
    Keywords : local exhaust ventilation; human exposure;

    Abstract : Local exhaust (LE) ventilation is a ventilation technique where contaminated air is locally extracted close to the contaminant source usually with the purpose to reduce the exposure of workers to dust, fumes or vapour, which can be hazardous to their health. The performance of a LE installation depends however on many influential factors, and there is not yet an international standardized way to test LE constructions. READ MORE
