1. 1. An Algorithmic Framework for Intelligent Concrete Structural Defects Detection and Classification

   Författare :Ali Mirzazade; Björn Täljsten; Cosmin Popescu; Thomas Blanksvärd; Diogo Rodrigo Ferreira Ribeiro; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil Engineering Structures; defect detection; Structural Health Assessment; Bridge Inspection; Computer Vision; Point-Cloud Generation; Severity Assessment; Machine Learning Regression; Bridge 3D Modeling; Unmanned Inspections; Byggkonstruktion; Structural Engineering;

   Sammanfattning : The primary objective of inspecting concrete civil structures is to gather information concerning the deterioration of concrete elements, including issues like concrete cover cracking, delamination, or corrosion. Typically, this data is documented through field inspection notes, hand-drawn sketches, and photographs. LÄS MER

3. 2. Testing and finite element modeling of wooden stairs and bridge decks

   Författare :Anna Pousette; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : Development of new products in the joinery industry has traditionally been based on testing of prototypes. Computer-aided design tools and finite element analysis can supplement traditional prototype testing and improve the product development process. LÄS MER

4. 3. Structural Analysis of Existing RC Bridge Deck Slabs Structural Analysis of Existing RC Bridge Deck Slabs

   Författare :Jiangpeng Shu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load-carrying capacity; assessment; Reinforced concrete RC bridge deck slabs; structural behaviour; Finite element FE analyses;

   Sammanfattning : Due to ageing of the bridge stock, continuously increasing load requirements, the need for assessing existing bridges is becoming increasingly important. Reinforced concrete (RC) bridge deck slabs are among the most critical parts to the load carrying capacity of bridges. LÄS MER

5. 4. Advancing Modeling and Tracking of Deformable Linear Objects for Real-World Applications

   Författare :Yuxuan Yang; Todor Stoyanov; Johannes A Stork; Ville Kyrki; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deformable Linear Object; Model Learning; Model-based Control; Tracking; Robustness;

   Sammanfattning : Deformable linear objects (DLOs), such as cables, wires, ropes, and sutures, are important components in various applications in robotics. Although automating DLO manipulation tasks through robot deployment can offer benefits in terms of cost reduction and increased efficiency, it presents difficult challenges. LÄS MER

7. 5. Mechanisms of Blister Formation on Concrete Bridge Decks with Waterprooving Asphalt Pavement Systems

   Författare :Biruk Wobeshet Hailesilassie; Björn Birgisson; Lars-Olof Nilsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blister growth; PBM waterproofing membrane; orthotropic material; biaxial test; peeling test; elliptical blister growth;

   Sammanfattning : Bridge decks are commonly subjected to harsh environmental conditions that often lead to serious corrosion problems triggered by blisters under the hot mix asphalt bridge deck surfacing and secretly evolving during weather exposure until damage is often detected too late. Blisters may form under both the waterproofing dense mastic asphalt layer or under the waterproofing membrane which is often applied as additional water protection under the mastic asphalt (MA).
