1. 21. Evaluating the performance of cone crushers under various feeding conditions using DEM and coupled DEM-MBS simulations

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : John Larsson; [2023]
   Keywords : Discrete Element Method; DEM; Cone Crusher; Segregation; Co-Simulation; Multi-body Dynamics; MBD;

   Abstract : Cone crushers are used in both the construction and mining industries for the production of aggregates and extraction of ores. Aggregates are used when building for example houses, roads and railways, hence the cone crushers are a vital part of modern society. READ MORE

3. 22. Assessment of oyster mushroom production employing urban-based materials in Stockholm Stad

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Mio Fagerström; [2023]
   Keywords : Industrial symbiosis; residual waste streams; Pleurotus ostreatus; Oyster mushroom cultivation; Circular economy; Industriell symbios; restavfallsströmmar; Pleurotus Ostreatus; Ostronskivlings odling; cirkulär ekonomi;

   Abstract : This thesis investigates the opportunities and challenges regarding urban oyster mushroomproduction (Pleurotus Ostreatus) employing urban-based materials in Stockholm Stad as agrowing medium. Additionally, the availability of the five most suitable substrates has beenfurther explored with the indicator’s availability in Stockholm Stad, and the Biologicalefficiency (BE%) for a suitable growing medium and the quantity of the substrates have beenmapped out.

4. 23. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

   University essay from Umeå universitet/Institutionen för fysik

   Author : Klara Lindroth; [2023]
   Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

   Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

5. 24. Challenges and success factors for scaling up an upcycling value chain : A case study and material flow analysis on public school craft classes in Stockholm

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Hsu-Kai Weng; [2023]
   Keywords : Wood upcycling; Textile upcycling; Craft education; Material flow analysis; Circular economy;

   Abstract : Upcycling is the process of repurposing discarded materials into new products of higher value, and holds significant potential for sustainable waste management. This thesis explores the challenges and opportunities involved in expanding upcycling practices in the city of Stockholm, with a specific focus on craft classes in public schools. READ MORE

6. 25. Beyond Disruptions: Optimizing Supply Chain Resilience : A qualitative and quantitative analysis of the aftermarket supply chain

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Sara Andersson; Jesper Karlsson; [2023]
   Keywords : Modelling Supply Chain Resilience; Supply Chain Disruptions; Semi-structured Interviews; Robustness Analysis; Flow Optimisation; Supply Chain Network Topology; Performance Measure;

   Abstract : The world is changing, what has been known to work has been put to the test when both the geopolitical and the environmental climate are changing. War, a pandemic, material shortage, financial difficulties and an overall dis- tressed global transportation sector have shown that the ever-more important topic of resilience is crucial to stay relevant in today’s competitive markets.
