1. 21. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Svante Rosenlind; [2023]
   Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

   Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

3. 22. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

   University essay from Lunds universitet/Innovation

   Author : Tora Abrahamsson; Juliana Kalling; [2023]
   Keywords : Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

   Abstract : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. READ MORE

4. 23. Climate and economic implications of structure and façade materials on a building's life cycle performance : A case study of a multi-family building in Sweden

   University essay from Uppsala universitet/Byggteknik och byggd miljö

   Author : Maximilian Jatzkowski; [2023]
   Keywords : life cycle assessment; life cycle analysis; multi-family building; life cost analysis; facade; environmental analysis; livscykelanalys; miljöanalys; flerbostadshus; livskostnadsanalys; stomme; fasad;

   Abstract : This study has been conducted in cooperation with OBOS Kärnhem. The objective of the study is to assess environmental impacts from different structural and facade materials to find a configuration with the lowest impact, and to assess the economic implications of different structural and façade materials.

5. 24. Environmental impact assessment of construction materials in a battery factory

   University essay from KTH/Hållbara byggnader

   Author : Monica Angulo Diaz; [2023]
   Keywords : ;

   Abstract : This paper explores the environmental impact of construction materials in a battery factory, with a particular focus on their global warming potential, acidification, and eutrophication potential. The production of construction materials is found to contribute significantly to the overall environmental impact of a building, with steel and concrete identified as having the highest impact among the materials analyzed.

6. 25. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

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

   Author : Ahmad Talaat Hifzy; [2023]
   Keywords : Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

   Abstract : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. READ MORE
