  1. 21. Design and investigation of a pulsating heat pipe for electronic cooling

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Sulafa Hammad; [2023]
    Keywords : Pulsating heat pipes PHP ; Electronic cooling; two phase flow heat transfer; Technology and Engineering;

    Abstract : The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. READ MORE

    University essay from Uppsala universitet/Företagsekonomiska institutionen

    Author : Frida Söderquist; Linnéa Söderquist; [2023]
    Keywords : Business-Sociopolitical Network; Context; Power Dynamics; Ties; Resource Dependency; Relationship Maintenance; Institutional Forces; Korea-Japan Trade Dispute; Business-sociopolitiskt nätverk; kontext; maktdynamik; förbindelser; resursberoende; upprätthållande av relation; institutionella tryck; Korea-Japan handelskonflikt;

    Abstract : This study examines power factors (resource dependence, attraction of relationship maintenance, and institutional forces) in relation to actors' behaviors and ties of varying strength between them within a network of business and sociopolitical spheres. The focus is on Samsung Electronics and Asahi Breweries in the context of the ROK-Japan trade dispute (2019-2023). READ MORE

  4. 23. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Abstract : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. READ MORE

  5. 24. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

    University essay from KTH/Tillämpad fysik

    Author : Xinyi Wei; [2023]
    Keywords : Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

    Abstract : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.

  6. 25. Design of an Embedded Torque Sensor : Based on Volumetric Strain induced Differential Air Pressure

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Wen Qi; [2022]
    Keywords : Torque; Electronics; Gas sealing; Pressure measurement;

    Abstract : This paper proposes a torque sensor based on the differential air pres- sure measurement method using a new embedded structure. The pro- posed sensor design is an improvement over the previous sensor design. The mechanical sensitivity, resolution, and stress distribution of the new sensor are analyzed by finite element modeling. READ MORE
