  1. 1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sara Muminovic; Christina Lindén; [2023]
    Nyckelord :Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Sammanfattning : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. LÄS MER

  3. 2. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Alazne Irene Varela Santana; [2023]
    Nyckelord :stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

    Sammanfattning : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.

  4. 3. En experimentell simulering av luftdistributionens inverkan på spridningen av luftburna virus och bakterier : Laboratorieförsök med spårgas

    Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Jasmina Balic; Stella Ericson; [2023]
    Nyckelord :Covid-19; CO2; Breathing zone; Displacement ventilation; Mixing ventilation; Thermal doll; Tracer gas measurements; Transfer probability; Andningszon; CO2; Covid-19; Deplacerande ventilation; Omblandande ventilation; Spårgasmätningar; Termisk docka; Överföringssanolikhet;

    Sammanfattning : Detta examensarbete presenterar resultatet från en experimentell studie med syfte att undersöka sambandet mellan ventilation i kontor och smittspridning av luftburna virus och bakterier. Fokuset i studien har framför allt riktats mot coronaviruset och även avgränsats till att enbart studera omblandande-, och deplacerande ventilation under den experimentella delen. LÄS MER

  5. 4. Diffuser: Packet Spraying While Maintaining Order : Distributed Event Scheduler for Maintaining Packet Order while Packet Spraying in DPDK

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Vignesh Purushotham Srinivas; [2023]
    Nyckelord :Packet scheduling; Scheduling; Out of order; Data plane development kit; Parallel processing; Network processor; Paketschemaläggning; Schemaläggning; oordning; Dataplansutvecklingskit; Parallell bearbetning; Nätverksprocessor;

    Sammanfattning : The demand for high-speed networking applications has made Network Processors (NPs) and Central Computing Units (CPUs) increasingly parallel and complex, containing numerous on-chip processing cores. This parallelism can only be exploited fully by the underlying packet scheduler by efficiently utilizing all the available cores. LÄS MER

  7. 5. Computational Fluid Dynamics of the flow in a diffuser : - like geometry

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Rasmus Johansson Oskarsson; [2023]
    Nyckelord :Fluid mechanics; Flow simulation; RANS; Flow separation; Diffuser;

    Sammanfattning : Simulations were performed to investigate flow separation of an asymmetricdiffuser - like geometry. The geometry used for the simulations was modeledafter an experimental setup with recorded flow data, which was compared tothe simulated data. For all simulations, steady state flow at the inlet was usedwith the assumption of a 2D flow. LÄS MER
