  2. 1. Interaction Infrastructure : a Holistic Approach to Support Co-Modality for Freight

    Author : Inger Gustafsson; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Logistics; Co-modality; Transport policy; Information;

    Abstract : In this thesis I have illustrated how information is essential for the management of transport chains. I have explored the notion of transparency as well as its importance for transport chains. The conclusion drawn is that transparency does not mean that every player should know everything at all times. READ MORE

  4. 2. Identifying locally induced loads in hard rock tunnel linings by distributed optical fibre sensors

    Author : August Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed optical fibre sensors; Structural health monitoring; Tunnel lining experiments;

    Abstract : In an infrastructure system, tunnels enable fast means of transportation in impassable terrain or city areas. However, inspections and maintenance can be expensive due to long down time and, in hard rock tunnels, the complexity of the structure may lead to over designing. READ MORE

  5. 3. Lessons Learned in Structural Health Monitoring of Bridges Using Advanced Sensor Technology

    Author : Merit Enckell; Johan Silfwerbrand; Konrad Bergmeister; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; Structural Health Monitoring System; bridges; sensor technology; emerging technology; fibre optics; fibre optic sensors concrete; creep; shrinkage; steel; distributed sensors; crack detection; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Structural Health Monitoring (SHM) with emerging technologies like e.g. fibre optic sensors, lasers, radars, acoustic emission and Micro Electro Mechanical Systems (MEMS) made an entrance into the civil engineering field in last decades. Expansion of new technologies together with development in data communication benefited for rapid development. READ MORE

  6. 4. Distributed Massive MIMO : Random Access, Extreme Multiplexing and Synchronization

    Author : Unnikrishnan Kunnath Ganesan; Erik G. Larsson; Emil Björnson; Alexey Vinel; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The data traffic in wireless networks has grown tremendously over the past few decades and is ever-increasing. Moreover, there is an enormous demand for speed as well. READ MORE

  7. 5. Novel approaches for monitoring effects of steel corrosion in reinforced concrete

    Author : Andreas Alhede; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reinforced Concrete; Neutron and X-ray Computed Tomography; Corrosion; Distributed Optical Strain Sensing;

    Abstract : Corrosion of steel reinforcement is a common deterioration mechanism in reinforced concrete structures. This deterioration impacts the safety of the structure and may require extensive repair and maintenance work. There is currently no method available for accurately measuring internal corrosion damage non-destructively. READ MORE
