1. 6. Textured insert for improved heat extraction in combination with high-pressure cooling in turning of superalloys

   Författare :Nageswaran Tamil Alagan; Tomas Beno; Uta Klement; Anders Wretland; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; High-pressure coolant; Heat dissipation; Textured insert; Tungsten carbide; Tool life; Tool wear; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Heat generated in a machining process is a common and critical obstacle faced in today's machining industries. The heat generated in the cutting zone has a direct negative influence on the tool life which, in turn contributes to increase the manufacturing costs. LÄS MER

3. 7. Lower Bounds and Trade-offs in Proof Complexity

   Författare :Susanna F. de Rezende; Jakob Nordström; Amit Chakrabarti; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proof complexity; trade-offs; lower bounds; size; length; space; Computer Science; Datalogi;

   Sammanfattning : Propositional proof complexity is a field in theoretical computer science that analyses the resources needed to prove statements. In this thesis, we are concerned about the length of proofs and trade-offs between different resources, such as length and space. LÄS MER

4. 8. Traffic Management in Software-Defined Data Center Networks

   Författare :Cristian Hernandez Benet; Andreas Kassler; Boris Koldehofe; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SDN; data center; load-balancing; traffic management; EVPN; big data; programmable data plane; Computer Science; Datavetenskap;

   Sammanfattning : Traffic management in data centers is paramount to improving network and application performance, thereby improving the quality of service by reducing network congestion, packet loss, and latency. However, the deployment and configuration of traffic management techniques are challenging due to diverse data-center traffic characteristics, large data center topologies, and the interplay of different protocols at the routing, transport, and link layer.

5. 9. Machinability variations in alloy 718 turbine components

   Författare :Pajazit Avdovic; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variation in tool; hardness; Machining; flank wear; notch wear; alloy 718; grain size; instability; variation in material;

   Sammanfattning : Machinability Variations in Alloy 718 Turbine Components PAJAZIT AVDOVIC Department of Materials and Manufacturing TechnologyChalmers University of Technology AbstractAlloy 718 has a reputation for being very troublesome during the cutting process. It was suspected that this material was too hard and having too fine grain size and that these characteristics caused damage to cutting tools during processing. LÄS MER
