1. 11. Energy Usage in Supermarkets - Modelling and Field Measurements

   Författare :Jaime Arias; Per Lundqvist; Denis Clodic; KTH; []
   Nyckelord :Supermarket; Energy Performance; System Analysis; Modelling; Simulation; Field Measurements; Refrigeration Systems; Indirect Systems; Heat Recovery; Floating Condensing; TEWI; LCC.; NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : This thesis investigates a special type of energy system, namely energy use in supermarkets through modelling, simulations and field studies. A user-friendly computer program, CyberMart, which calculates the total energy performance of a supermarket, is presented. LÄS MER

3. 12. Improving Machining System Performance through designed-in Damping : Modelling, Analysis and Design Solutions

   Författare :Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

   Sammanfattning : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. LÄS MER

4. 13. Design of Microstructures in Thermal Barrier Coatings : A Modelling Approach

   Författare :Mohit Kumar Gupta; Per Nylén; Robert Vaβen; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal barrier coatings; microstructure; thermal conductivity; Young‘s modulus; lifetime; finite element modelling; design; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Plasma sprayed Thermal Barrier Coating systems (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. The material that is most commonly used in these applications is Yttria Stabilized Zirconia (YSZ) because of this ceramic’s favourable properties, such as low thermal conductivity, phase stability to high temperature, and good erosion resistance.

5. 14. Performance of Stress-Laminated-Timber Bridge Decks

   Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; butt joints; non-linear modelling; stress-laminated timber; linear modelling; prestressing; timber bridges; interlaminar slip; FE modelling; laboratory tests; durability;

   Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from a number of timber or glulam beams positioned side by side and stressed together using high-strength steel bars. LÄS MER

7. 15. Unchaining Microservice Chains : Machine Learning Driven Optimization in Cloud Native Systems

   Författare :Michel Gokan Khan; Javid Taheri; Andreas Kassler; Stefan Schulte; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cloud Native Computing; Service Mesh; Performance Modelling; Performance Optimization; Performance Simulation; Machine Learning; Resource Allocation; Computer Science; Datavetenskap;

   Sammanfattning : As the cloud native landscape flourishes, microservices emerge as a central pillar for contemporary software development, enabling agility, resilience, and scalability in modern computing environments. While these modular services promise opportunities, particularly in the transformative ecosystem of 5G and beyond, they also introduce a myriad of complexities. LÄS MER
