  1. 1. Conjugate Heat Transfer Analysis of HPGP Thruster

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lisa Svensson; [2024]
    Nyckelord :aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Sammanfattning : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. LÄS MER

  3. 2. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Författare :Fritjof Nilsson; Yanjun Peng; [2023]
    Nyckelord :Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Sammanfattning : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. LÄS MER

  4. 3. Predicting Cryptocurrency Prices with Machine Learning Algorithms: A Comparative Analysis

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Harsha Nanda Gudavalli; Khetan Venkata Ratnam Kancherla; [2023]
    Nyckelord :Bitcoin; Cryptocurrency; Machine Learning;

    Sammanfattning : Background: Due to its decentralized nature and opportunity for substantial gains, cryptocurrency has become a popular investment opportunity. However, the highly unpredictable and volatile nature of the cryptocurrency market poses a challenge for investors looking to predict price movements and make profitable investments. LÄS MER

  5. 4. Performance of State Distributing Message-Oriented Middleware Systems Using Publish-Subscribe

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Robin Edlund; Johannes Kettu; [2023]
    Nyckelord :Message-oriented middleware; publish-subscribe; topic; tactical simulator; flight simulator; Meddelandeorienterad mellanprogramvara; publish-subscribe; topic; taktisk simulator; flygsimulator;

    Sammanfattning : Distributed simulations require efficient communication to represent complex scenarios, which presents a great challenge. This paper investigates the use of message-oriented middleware (MOM) to address this challenge by integrating the flight simulator X-Plane with the tactical simulator TACSI and evaluating the performance of different data transfer approaches.

  7. 5. Resistensbestämning av bakterier : Studie av odlingsbuljongens påverkan på resultatet i tidigare rapporterad forskning samt genom experimentell undersökning.

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Åsa Svensson; [2023]
    Nyckelord :Klebsiella pneumoniae; meropenem; broth microdilution; susceptibility testing; minimum inhibitory concentration; Klebsiella pneumoniae; meropenem; buljongspädning; resistensbestämning; minsta inhiberande koncentration;

    Sammanfattning : Ökande antibiotikaresistens utgör en allvarlig samhällsutmaning. För resistensbestämning av bakterier används standardmetoden buljongspädning. Då bestäms minsta inhiberande koncentration (MIC) som den lägsta koncentration av antibiotika som kan förhindra tillväxt. LÄS MER
