  1. 1. Concept Design and Prototyping of a Test Rig for In Vitro Hemolysis Assessment of Pulsatile Blood Pumps : A design with an Improved Blood Filling and De-airing Interface

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Yun-Ting Lee; [2022]
    Nyckelord :Hemolysis assessment; test rig design; mock loop; pulsatile flow blood pumps; blood filling and de-airing processes; Hemolysbedömning; testriggdesign; mock loop; pulserande blodpumpar; blodfyllning och avluftningsprocesser;

    Sammanfattning : Hemolysis assessment of heart pumps is necessary to be carried out before progressing to clinical trials. Blood pump hemolysis assessment standards, such as ASTM F1830 and F1841, were initially based on continuous flow pumps and included the pulsatile flow pumps later in 2019. LÄS MER

  2. 2. Thermal transients study for the ESS target helium cooling system

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hannes Björk; [2022]
    Nyckelord :ESS; European Spallation Source; models; Modelica; system identification; sensors; cooling system; Technology and Engineering;

    Sammanfattning : The European Spallation Source (ESS) is going to be the worlds most powerful spallation source once in full operation. The neutrons used by scientists and engineers are spallated from a rotating wheel of wolfram, being bombarded by accellerated protons. LÄS MER

  3. 3. Utveckling av magnetiskt motstånd till träningsmaskin : En innovativ lösning till Nordic SkiCross

    Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap

    Författare :Felicia Sandin; Klara Rubin; [2021]
    Nyckelord :Träningsmaskin; Nordic SkiCross; magnetism; magnetbroms; magnetiskt motstånd; virvelströmmar; Schiebers modell; designprocess; Exercise machine; Nordic SkiCross; magnetism; magnetic break; magnetic resistance; eddy current; Schieber’s model; design process;

    Sammanfattning : Nordic SkiCross är en träningsmaskin som produceras av företaget Motiofy, det är en maskin som efterliknar hela kroppens rörelse vid klassisk längdskidåkning. Syftet med denna studie är att utveckla ett magnetiskt motstånd till Nordic SkiCross för att reducera slitage samt att underlätta motståndregleringen. LÄS MER

  4. 4. Estimation of Blocked Forces in an Assembly with Rear Drive Unit as a Source

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Srujeeth Khanna Bala; [2021]
    Nyckelord :Component based TPA; source characterized forces; FEM; Contact forces; ISO20270:2019; Blocked forces; Automotive; NVH; sound and vibration; komponentbaserad TPA; karaktärisering av bullerkällor; FEM; kontaktkrafter; blockerade krafter; bilindustri; ljud och vibrationer; ISO20270:2019;

    Sammanfattning : Experimental validations are widely used for studying dynamic structural behaviors and these studies involve defining the structures completely as being used in real time. While in numerical simulations such detailed features are not specified to ease the computation, thereby deviating from accurate results. LÄS MER

  5. 5. Simulation and Physical Implementation of a Test Rig for Realistic Hail Impact Testing

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :HANNA HERMANSSON; ALMIDA WINQUIST DE VAL; [2021]

    Sammanfattning : Hail storms, with hail commonly near 50 mm in diameter that travel with storm wind sabove 25 m/s, cause damages of a large magnitude throughout the globe, with places like USA, Australia and India suffering the greatest. These damages have serious consequences, not least telecommunication products mounted in exposed places. LÄS MER
