2. 1. Evaluation of Road Equipment with Emphasis on Condition Assessment

   Author : Sven-Olof Lundkvist; Ulf Isacsson; Rolf Magnusson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road equipment; Condition assessment; State-of-the-art; Mobile measurement; Road marking; Road sign; Post delineator; Traffic light; Street lighting; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : This doctoral thesis deals primarily with condition assessment of road equipment. The road equipment concept is defined by five main groups, road lighting, fences and barriers, vertical signs, horizontal signs and traffic signals, respectively. READ MORE

4. 2. An experimental investigation of flow in a Kaplan runner : steady-state and transient

   Author : Kaveh Amiri; Bjarne Børresen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Water turbines are since some years widely used for grid stabilization purposes according to their exceptional load variation capability which gives them the ability to compensate grid fluctuations initiated by the customer’s consumption or intermittent electricity production systems such as wind and solar power. Different renewable power generation technologies can be combined in mini-grids to electrify isolated villages and extend existing grid networks. READ MORE

5. 3. Fluid Power Applications Using Self-Organising Maps in Condition Monitoring

   Author : Anders Zachrison; Jan-Ove Palmberg; Magnus Sethson; Richard Burton; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; pneumatic; self-organizing maps; condition monitoring; Signal processing; Signalbehandling;

   Abstract : Condition monitoring of systems and detection of changes in the systems are of significant importance for an automated system, whether it is for production, transport, amusement, or any other application. Although condition monitoring is already widely used in machinery, the need for it is growing, especially as systems become increasingly autonomous and self-contained. READ MORE

6. 4. Failure Monitoring and Asset Condition Assessment in Water Supply Systems

   Author : Dalius Misiunas; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; reglerteknik; robotteknik; Automatiska system; Water supply; failure; detection; monitoring; location; bursts; hydraulics; leakage; asset management; condition assessment; pipelines; pipe networks; Automation; control engineering; robotics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Abstract : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. READ MORE

7. 5. Automated Gravel Road Condition Assessment : A Case Study of Assessing Loose Gravel using Audio Data

   Author : Nausheen Saeed; Moudud Alam; Roger G. Nyberg; Diala Jomaa; Mirka Kans; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Gravel roads; road maintenance; convolutional neural network CNN ; SVM; decision trees; ensemble bagged trees; GoogLeNet; ResNet50; ResNet18; sound analysis;

   Abstract : Gravel roads connect sparse populations and provide highways for agriculture and the transport of forest goods. Gravel roads are an economical choice where traffic volume is low. In Sweden, 21% of all public roads are state-owned gravel roads, covering over 20,200 km. READ MORE
