  1. 1. On the On-line Tools for Treatment of Deterioration in Industrial Processes

    Författare :Christer Karlsson; Erik Dahlquist; Risto Ritala; Mälardalens högskola; []
    Nyckelord :Deterioration; Industrial Processes; Sensors; Process models; Neural networks; Bayesian networks; Data reconciliation; Steam turbines; Boilers; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : For industrial processes high availability and efficiency are important goals in plant operation. This thesis presents studies and development of tools for on-line treatment of process deterioration and model and sensor errors in order to achieve these goals. LÄS MER

  3. 2. Deterioration Models and Road Capital as Tools in Performance Contracts for Pavement Maintenance

    Författare :Peter Ekdahl; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; pavement management system; performance contract; pavement maintenance; deterioration model; Technological sciences; road capital; Social sciences; Samhällsvetenskaper;

    Sammanfattning : A reorganization of the Swedish National Road Administration (SNRA) has urged a demand to work as a professional agency only, without any work by direct labor. This structure has enforced a change in how to handle the pavement maintenance and performance contracts are being promoted since they encourage product development and sustainability. LÄS MER

  4. 3. Documentation and Maintenance Planning Model – DoMaP A response to the need for conservation and long-term maintenance of façades of modern multi-apartment buildings Based on case studies in Göteborg in Sweden

    Författare :Pär Meiling; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; public housing companies; façade-materials; Sustainable integrated conservation; long-term maintenance operations; deterioration; optical measurement techniques; generic multi-apartment buildings;

    Sammanfattning : Sustainable maintenance and renovation of façades on generic multi-apartment buildings from late 1950s through 70s constitute vital challenges for the housing companies owned by City of Göteborg. These challenges comprise a wide array of issues, such as deterioration and damages in occurring façade materials, status assessments, technical improvements, reduction of energy consumption, and up-keeping of housing qualities and tenants attraction.

  5. 4. A systemic traffic accident model

    Författare :Yu-Hsing Huang; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; trafikolyckor; trafiksäkerhet; traffic safety; traffic accidents; Computer science; Datavetenskap;

    Sammanfattning : Accident models are essential for all efforts in safety engineering. They influence the investigation and analysis of accidents, the assessment of systems and the development of precautions. Looking at accident statistics, the trend for Swedish roads is not pointing towards increased safety. LÄS MER

  7. 5. Durability of timber members : Moisture conditions and service life assessment of bridge detailing

    Författare :Jonas Niklewski; Avdelningen för Konstruktionsteknik; []
    Nyckelord :wood; spruce; moisture; durability; decay; service life; detailing; model;

    Sammanfattning : The longevity of timber structures in exposed outdoor environments is often perceived to be unreliable as compared with that of concrete and steel structures. This situation is exacerbated to some extent by the fact that the European commission for standardization (CEN) currently provides no quantitative method for service life assessment of timber structures.
