  2. 1. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

    Author : Hans Kolsters; KTH; []
    Keywords : Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

    Abstract : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.

  4. 2. Programming Model and Protocols for Reconfigurable Distributed Systems

    Author : Cosmin Ionel Arad; Seif Haridi; Gregory Chockler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; distributed systems; programming model; message-passing concurrency; nested hierarchical composition; reactive components; software architecture; dynamic reconfiguration; multi-core; discrete-event simulation; peer-to-peer; testing; debugging; distributed key-value stores; data replication; consistency; linearizability; network partition tolerance; consistent hashing; self-organization; scalability; elasticity; fault tolerance; consistent quorums;

    Abstract : Distributed systems are everywhere. From large datacenters to mobile devices, an ever richer assortment of applications and services relies on distributed systems, infrastructure, and protocols. Despite their ubiquity, testing and debugging distributed systems remains notoriously hard. READ MORE

  5. 3. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties

    Author : Mikael Danielsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; IPN; core material; low temperature; polyurea; polyethersulfone; gradient structure; foam; PVC; sandwich; waste; fire; smoke; toxicity; mechanical properties; Inter Penetrating Polymer Network; dynamic properties; high temperature;

    Abstract : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. READ MORE

  6. 4. Investigation of Suffusion in Glacial Till Dam Cores : Testing methods and critical hydraulic gradients

    Author : Ingrid Silva; Jan Laue; Peter Viklander; Thomas Pabst; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal erosion; suffusion; glacial till; dam cores; dams; experimental investigation; hydraulic gradient; testing methods; cohesionless soils; granular soils; Geoteknik; Soil Mechanics;

    Abstract : Suffusion is an internal erosion mechanism that occurs in embankment dams when fine grained particles in the dam core are washed out by seepage. Initiation of internal erosion depends mainly on three major factors: grain size distribution of the soil, stress conditions and hydraulic gradient; whilst its continuation depends on the properties of the filter.

  7. 5. Server-Aided Privacy-Preserving Proximity Testing

    Author : Ivan Oleinikov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active security; MPC; privacy; secure proximity testing;

    Abstract : Proximity testing is at the core of many Location-Based online Services (LBS) which we use in our daily lives to order taxis, find places of interest nearby, connect with people. Currently, most such services expect a user to submit his location to them and trust the LBS not to abuse this information, and use it only to provide the service. READ MORE
