1. 11. Unsupervised feature learning applied to condition monitoring

   Författare :Sergio Martín del Campo Barraza; Fredrik Sandin; Kjersti Engan; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : Improving the reliability and efficiency of rotating machinery are central problems in many application domains, such as energy production and transportation. This requires efficient condition monitoring methods, including analytics needed to predict and detect faults and manage the high volume and velocity of data. LÄS MER

3. 12. Position Estimation in Uncertain Radio Environments and Trajectory Learning

   Författare :Yuxin Zhao; Fredrik Gunnarsson; Fredrik Gustafsson; Carsten Fritsche; Henk Wymeersch; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : To infer the hidden states from the noisy observations and make predictions based on a set of input states and output observations are two challenging problems in many research areas. Examples of applications many include position estimation from various measurable radio signals in indoor environments, self-navigation for autonomous cars, modeling and predicting of the traffic flows, and flow pattern analysis for crowds of people.

4. 13. Content and Resource Management in Edge Networks

   Författare :Mohammadhassan Safavi; Nätverk och säkerhet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Content delivery networks; Machine Learning; Internet of Things; Fog Computing;

   Sammanfattning : In this thesis, we investigate and develop new methods for efficient and functional use of resources in edge networks. Setting this work aside from previous work, we study User Generated Content (UGC) such as social media information and data generated in the new emerging Internet of Things systems. LÄS MER

5. 14. Novel beam shaping and computer vision methods for laser beam welding

   Författare :Yongcui Mi; Antonio Ancona; Fredrik Sikström; Isabelle Choquet; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser beam welding; Beam shaping; Deformable mirror; Process monitoring; Process control; Model validation; Computer vision; Machine learning; Butt joint; T-joint.; Lasersvetsning; Beam shaping; Deformerbar spegel; Processövervakning; Processkontroll; Modellvalidering; Datorsyn; Maskininlärning; Butt joint; T-fogar;

   Sammanfattning : Laser beam welding has been widely applied in different industrial sectors due to its unique advantages. However, there are still challenges, such as beam positioning in T-joint welding, and gap bridging in butt joint welding,especially in the case of varying gap width along a joint. LÄS MER

7. 15. Motivation pour apprendre une langue étrangère – une question de visualisation? : Les effets de trois activités en cours de français sur la motivation d’élèves suédois

   Författare :Céline Rocher Hahlin; Franska; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; French; Motivation; Dörnyei; Ideal Language Self; Ideal L3 Self; Intended effort; language acquisition; L3; language learning; foreign language; classroom activities;

   Sammanfattning : Despite the vast research on motivation and foreign language acquisition during the last decades, little is known about the motivational effects of concrete pedagogical activities in the classroom. The work of, among others, Z. Dörnyei shows that imagined reality can have positive effects on language learning outcomes. LÄS MER
