  2. 6. Integration of building product data with BIM – Semantic representation of product data

    Author : Rahel Zeleke Kebede; Peter Johansson; Annika Moscati; He Tan; Ekaterina Petrova; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BIM; Information exchange; Product data; Semantic web technologies; Linked Data; Design science; BIM; Informationsutbyte; Produktdata; Semantiska Nätverk; Länkad Data; DSR;

    Abstract : The adoption and implementation of Building Information Modelling (BIM), as technologies and processes, in the Architecture, Engineering and Construction (AEC) industry marked a significant step forward in advanced digital transformation. One of the distinctive features of the AEC industry is that it necessitates a collaborative effort between several actors from different domains to realize building projects effectively. READ MORE

  4. 7. Diagnostic criteria and dose limiting approaches for image modalities in odontology

    Author : Daniel Benchimol; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Objectives: Technical innovations in radiography enable the development of new approaches to reduce the dose to patients. The aim of this thesis was to explore dose optimization approaches for the most frequently used radiographic modalities in dentistry. READ MORE

  5. 8. An Organizational Perspective on the Business Value of BIM

    Author : Susanna Vass; Tina Karrbom Gustavsson; Björn Berggren; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The architecture, engineering and construction (AEC) industry is often characterized by low productivity, poor quality, slow IT adoption and a low rate of innovation. Building Information Modelling (BIM) has been addressed as an IT based potential solution to many of the industry´s problem and BIM has received much attention in both industry and academia.

  6. 9. Digital Mammography with a Photon Counting Detector in a Scanned Multislit Geometry

    Author : Magnus Åslund; Mats Danielsson; Ehsan Samei; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mammography; digital; photon counting; scanning; detective quantum effciency; scattered radiation; automatic exposure control; Physics; Fysik;

    Abstract : Mammography screening aims to reduce the number of breast cancer deaths by early detection of the disease, which is one of the leading causes of deaths for middle aged women in the western world. The risk from the x-ray radiation in mammography is relatively low but still a factor in the benefit-risk ratio of screening. READ MORE

  7. 10. Image Quality Optimisation and Dose Management in CT, SPECT/CT, and PET/CT

    Author : Marcus Söderberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; SPECT; PET; dosimetry; image quality; optimisation; dose reduction; automatic exposure control; contrast medium; phantom; image reconstruction; human observer;

    Abstract : The significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.
