2. 21. Automation of Load Haul Dump machines : comparative performance analysis and maintenance modeling

   Author : Anna Gustafson; Sunniva Haugen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Abstract : The Load Haul Dump (LHD) machine and its operating environment create a complex system. Mine productivity depends on the operation of the LHDs and on the mining environment, including fragmentation, size of boulders, navigation techniques etc. Traditional navigation techniques require a lot of infrastructure to accommodate automatic operation.

4. 22. Probabilistic Sequence Models with Speech and Language Applications

   Author : Gustav Eje Henter; W. Bastiaan Kleijn; Arne Leijon; Gernot Kubin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

   Abstract : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. READ MORE

5. 23. Doing Things in Relation to Machines : Studies on Online Interactivity

   Author : Anders Olof Larsson; Pär Ågerfalk; Stefan Hrastinski; Else Nygren; Mark Aakhus; Uppsala universitet; []
   Keywords : ;

   Abstract : The Internet is often discussed in conjunction with various notions of interactivity. Recently, conceptualizations of a “Web 2.0″, mainly focusing on harnessing user-generated content, have grown increasingly common in both public discourse and among researchers interested in the continued growth and transformation of the Internet.

6. 24. Process Control and Simulation of Ferromagnetic Strip in the Power Transformers and Electrical Machines Applications : Electric power systems

   Author : Kourosh Mousavi Takami; Jafar Mahmoudi; Örjan Danielsson; Mihai Nicolescu; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strip; electrical machines; transformer; cold rolling mills; process; automation; control; Band; elektriska maskiner; transformatorer; kallvalsningsverk; processautomation; reglerteknik; Electric power engineering; Elkraftteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : This thesis investigates optimization of the control of electrical and thermal equipment by using FEM and CFD modeling in combination with dynamic simulation models. The thesis focuses on the production of electrical strips and the control system with the aim of reducing losses and improving magnetic properties. READ MORE

7. 25. Performance Aspects of Databases and Virtualized Real-time Applications

   Author : Christine Niyizamwiyitira; Lars Lundberg; Mikael Svahnberg; Richard Chbeir; Blekinge Tekniska Högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SQL and NoSQL database; Bigdata management systems; Structured and non-structured Database Evaluation; Voice-driven web; Multicore performance prediction; Hard real-time Scheduling; Virtual Multiprocessor Scheduling;

   Abstract : Context: High computing system performance depends on the interaction between software and hardware layers in modern computer systems. Two strong trends that effect different layers in computer systems are that single processors are now more or less completely replaced by multiprocessors, which are often organized into clusters, and virtualization of resources.
