  1. 16. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialteori

    Författare :Judith Bösenecker; [2023]
    Nyckelord :sintering; heat transfer; transient heat conduction; sintring; värmeöverföring; transient värmeledning;

    Sammanfattning : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. LÄS MER

  3. 17. Optimal Knock Sensor Spatial Locations of In-line Combustion Engines : A Case Study of Scania Engines

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

    Författare :Hassan Hussein; [2023]
    Nyckelord :;

    Sammanfattning : In recent years, there has been a growing interest in utilizing knock sensors as a diagnostic tool for providing valuable insights into the combustion process. These sensors have demonstrated their potential to offer information regarding crucial parameters such as the start of combustion, heat release rate, misfire events, and valve events. LÄS MER

  4. 18. Axisymmetric capillary water waves on cylindrical fluid jets

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Anna-Mariya Otsetova; [2023]
    Nyckelord :Euler equations; Bernoulli boundary condition; Schauder estimates; nonlinear functional analysis; Mathematics and Statistics;

    Sammanfattning : In their paper, Vanden-Broeck, Miloh and Spivack (Wave Motion 27, 1998) describe two limiting behaviours of irrotational, axisymmetric capillary water waves using numerical methods. They found a two-parameter family of nontrivial solutions. Some solutions of small amplitude approach a uniform stream, while others approach a static configuration. LÄS MER

  5. 19. Design of a Bistable Origami Stent with Pneumatic Actuation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Michelle von Rosen; [2023]
    Nyckelord :;

    Sammanfattning : What if stents could be easier removed when complications arise or removed once theirjob has been done? No matter how perfect a stent design becomes, the fundamental issueis that a foreign object in the body under extended periods eventually will cause devicedegradation and complications. So instead of making a long-term solution of a perfectstent, the focus in this paper is redirected from expensive materials to a simple design,with simple materials. LÄS MER

  7. 20. Smart Locks – A case study for comparing Digital and Mechanical Locks from a Sustainable Perspective

    Master-uppsats, Lunds universitet/Teknisk logistik

    Författare :Rebecca Grenthe; Madeleine Andersson; [2023]
    Nyckelord :Sustainable supply chain; Life cycle assessment; Sustainability; Digitalization; Smart City Development; Environmental impact of digitalization; Sustainability reporting; Avoided emissions; Manufacturing process keys; digital locks; digital locks in a smart city.; Technology and Engineering;

    Sammanfattning : As carbon dioxide emissions increase along with the global average temperature, sustainable development is becoming more and more important in all sectors, and it is essential to act toward the reduction of emissions to counteract these dire consequences. Companies are expected to operate sustainably and responsibly with a minimized negative environmental impact alongside accelerating their digitalization journey to stay competitive in a rapidly changing environment.
