  2. 1. Modelling of Concrete Structures Subjected to Blast and Fragment Loading

    Author : Ulrika Nyström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamisk belastning; fiberarmerad betong; materialmodellering; numeriska studier; splitter; stötvåg; Betong;

    Abstract : Betong är tack vare sin låga kostnad och sitt stora användningsområde ett av de mest använda byggmaterialen i modern tid. Dess stora energiabsorberande förmåga vid höga tryck, samt det sega beteende betongkonstruktioner har vid väl utformad armering, gör betongen också lämplig i skyddande konstruktioner. READ MORE

  4. 2. Precision measurement instruments for machinery's mechanical compliance: design and operation : Measurement instruments for physics-based calibration of advanced manufacturing machinery

    Author : Nikolas Alexander Theissen; Andreas Archenti; Alexander Slocum; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement instruments; Machine tools; Industrial robots; Production Engineering; Industriell produktion;

    Abstract :  Precision Measurement Instruments (PMIs) for machinery’s mechanical compliance are tools to quantify mechanical load as well as length for measurement ranges of 0.1 µm to 10 m at uncertainty levels of 0.1 µm to 100 µm while exerting mechanical loads. READ MORE

  5. 3. Assessment of shear and energy‐absorption capacity of reinforced concrete elements under impulsive loads

    Author : Viktor Peterson; Anders Ansell; Mikael Hallgren; Yanyan Sha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impulsive loads; impact; blast; shear reinforcement; shear failure; Betongbyggnad; Concrete Structures;

    Abstract : Impulsive loads have been observed to cause brittle shear failure in reinforced concrete elements designed for ductile failure modes under static loads. Brittle failure modes exhibit poorer energy absorption capabilities compared to ductile flexural failure modes due to their limited deformation capacity, leading to premature failure. READ MORE

  6. 4. On the dynamics of footbridges : A theoretical approach and a comparison between running and walking loads

    Author : Daniel Colmenares; Raid Karoumi; Andreas Andersson; Mahir Ülker Kaustell; Pedro Museros Romero; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; footbridges; dynamics; human induced loads; human structure interaction; harmonic load; continuous beam; gångbroar; dynamik; fotgängarlast; samverkan mellan fotgängare och bro; harmonisk last; kontinuerlig balk.; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The dynamic behaviour of lightweight footbridges is often susceptible to HumanInduced Loads (HILs). Generally HILs are taken into account as moving harmonicfunctions in which the loading frequency represents the step frequency of the pedestrians. READ MORE

  7. 5. Cluster Scheduling and Management for Large-Scale Compute Clouds

    Author : Mina Sedaghat; Erik Professor; Omer Rana; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cloud computing; Scheduling; Resource Management;

    Abstract : Cloud computing has become a powerful enabler for many IT services and new technolo-gies. It provides access to an unprecedented amount of resources in a fine-grained andon-demand manner. To deliver such a service, cloud providers should be able to efficientlyand reliably manage their available resources. READ MORE
