  2. 16. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

    Author : Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

    Abstract : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. READ MORE

  4. 17. Towards a Scalable and Low-Latency Softwarized Mobile Packet Core Network

    Author : Van-Giang Nguyen; Anna Brunström; Karl-Johan Grinnemo; Javid Taheri; Christian Esteve Rothenberg; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mobile Packet Core; Evolved Packet Core; 5G; SDN; NFV; Scalability; Control Plane; User Plane; MME; UPF; VPP; Load Balancing; Auto-Scaling; Time-Critical; Low-Latency; Smart Grid; GOOSE; Computer Science; Datavetenskap;

    Abstract : The mobile packet core – a central part of the overall mobile cellular network – has a long history of evolution. Through the years, its architecture has been drastically changed to meet the demand coming from the fast growth in the number of devices as well as the introduction of new types of applications and services.

  5. 18. Improved PWR Core Characteristics with Thorium-containing Fuel

    Author : Cheuk Wah Lau; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; load-following; PWR; Thorium; xenon poisoning; core calculations;

    Abstract : Thorium is an element for possible use as nuclear fuel, because of the fertile property of Th-232, which could convert into U-233 after neutron capture and beta decays. However, thorium based fuels have not been successfully implemented, because of the high cost and the higher complexity compared with once-through uranium fuel. READ MORE

  6. 19. Laser-welded corrugated core steel sandwich bridge decks

    Author : Peter Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatigue; steel sandwich; Bridge deck; corrugated core; laser-weld;

    Abstract : Steel bridge decks are often used for applications when a lightweight structure is sought for. Conventional orthotropic steel decks suffers from drawbacks in several aspects, including high production costs and durability problems. READ MORE

  7. 20. Predicting surfacing internal erosion in moraine core dams

    Author : Hans Rönnqvist; Anders Wörman; Hans Bergh; Kaare Høeg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal erosion; internal stability; filters; moraine core; embankment dams; sinkholes; internal erosion assessment; Geoengineering and mining engineering; Geoteknik och gruvteknik;

    Abstract : Dams that comprise broadly and widely graded glacial materials, such as moraines, have been found to be susceptible to internal erosion, perhaps more than dams of other soil types. Internal erosion washes out fine-grained particles from the filling material; the erosion occurs within the material itself or at an interface to another dam zone, depending on the mode of initiation.
