  1. 1. 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

  5. 4. Developing A Network Algorithm for Demand Responsive Transit Service in A Rural Area of Sweden

    Master-uppsats, KTH/Transportplanering

    Författare :Benny Lam; Peng Shiyi; [2021]
    Nyckelord :DRT service in rural areas; network algorithm; heuristics algorithm; cost function; Anropstyrd trafik på landsbygden; nätverksalgoritmen; heuristisk algoritm; kostnadsfunktion;

    Sammanfattning : Based on the fact that accessibility in rural areas relies heavily on car traffic, call-driven traffic has been used in different regions to improve public transport usage in rural areas, while it has been difficult to maintain due to high maintenance and long waiting time. Over the past decade, a new demand response transit (DRT) service came into light, which combines with new technologies to provide a more attractive and efficient transport service. LÄS MER

  7. 5. Design and Implementation of CANopen - SAE J1939 Communication Gateway

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Peng Sun; [2021]
    Nyckelord :;

    Sammanfattning : Since the introduction of CAN (Controller Area Network), it has become the de-facto standard communication bus for in-vehicle networks. Several higher layer protocols are developed based on CAN to fit various application domains. SAE J1939 is the standard for communication in heavy-duty vehicles. LÄS MER
