  1. 1. Novel powertrain topologies for energy-efficient battery electric vehicles

    Författare :Yu Xu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System simulation; Battery electric vehicle; Electric powertrain; Powertrain topologies; Vehicle performance; Energy efficiency;

    Sammanfattning : The global transition towards sustainable transportation has underscored the importance of battery electric vehicles (BEVs), with a growing need for enhancement in powertrain energy efficiency to mitigate range anxiety and promote widespread adoption. In response to this need, there have been significant contributions from advancements on powertrain components, such as electric motors and inverters, towards increased energy efficiency. LÄS MER

  3. 2. Analysing hybrid drive system topologies

    Författare :Karin Jonasson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis a simulation model is presented that enables a comparison of different hybrid topologies, with respect to fuel consumption, emissions and performance. The obtained results stress the properties of the different topologies and form a foundation for the choice of hybrid topology. LÄS MER

  5. 4. Creating and maintaining topologies in wireless networks

    Författare :Tomas Johansson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : Wireless ad-hoc networks differs in many aspects compared to traditional infrastructured networks. Among other things, individual nodes cannot be expected to know the topology of the entire network. LÄS MER

  7. 5. What’s in? What’s out? And how did it get there? : Studies on topologies and insertion of membrane proteins

    Författare :Marie Österberg; Gunnar von Heijne; Peter Rehling; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane protein; topology; yeast; mitochondria; TIM23; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : Because of their hydrophobic and hydrophilic nature and the need for a lipid bilayer for retaining the native structure, membrane proteins are hard to study. Nevertheless, they are important, as many of our diseases are related to membrane proteins and around 60% of the different pharmaceutical drugs are directed against a membrane proteins [1]. LÄS MER
