2. 1. Modelling Aspects in Forming and Welding of Nickel-Base Superalloys

   Author : Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Juan Carlos Cante Teran; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alloy 718; Haynes 282; cold forming; hot forming; material characterization; GISSMO; welding; heat treatment; manufacturing chain; springback; shape distortions; dynamic strain aging; DSA; microstructure; Hållfasthetslära; Solid Mechanics;

   Abstract : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry because of major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the weight of vehicles while increasing the efficiency of the engine. READ MORE

4. 2. Modelling and Characterisation of the Martensite Formation in Low Alloyed Carbon Steels

   Author : Jessica Gyhlesten Back; Lars-Erik Lindgren; Göran Engberg; Bevis Hutchinson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dilatometry; Hardness; EBSD; Martensite; Austenite; Kurdjumov-Sachs; Phase transformation; Modelling; Material Mechanics; Materialmekanik; Steel Forming and Surface Engineering;

   Abstract : The current work contains experimental and theoretical work about the formation of martensite from the austenitic state of the steel Hardox 450. Simulation of rolling and subsequent quenching of martensitic steel plates requires a model that can account for previous deformation, current stresses and the temperature history, therefore dilatometry experiments were performed, with and without deformation.

5. 3. Scalable Validation of Data Streams

   Author : Cheng Xu; Tore Risch; Byung-Suk Lee; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Data Stream Management; Distributed Data Stream Processing; Data Stream Validation; Anomaly Detection; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Abstract : In manufacturing industries, sensors are often installed on industrial equipment generating high volumes of data in real-time. For shortening the machine downtime and reducing maintenance costs, it is critical to analyze efficiently this kind of streams in order to detect abnormal behavior of equipment. READ MORE

6. 4. Geographical Proximity Effects and Regional Strategic Networks

   Author : Heléne Lundberg; Martin Johanson; Jan-Åke Törnroos; Uppsala universitet; []
   Keywords : Business studies; Network; Regional development; Regional Strategic Networks; Företagsekonomi;

   Abstract : This thesis focuses on regional strategic networks (RSNs). RSNs are used as a tool for regional development with a view to strengthening regional relationship-development and networking by forming regional groups of actors. The thesis aims to clarify the nature of RSNs and the value of geographical proximity in both theoretical and practical terms. READ MORE

7. 5. Cost and benefits of cone beam computed tomography : for maxillary canines with eruption disturbance

   Author : Helena Christell; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostic methods; Cost-effectiveness; Economic evaluation; Systematic review; Cost-analysis; Radiology; Odontology; CBCT; Cone beam computed tomography;

   Abstract : I tandvården finns allt fler metoder för prevention, diagnostik och behandling. Eftersom resurserna är begränsade bör den metod väljas där nyttan uppväger kostnaden. Idag saknas dock vetenskapliga belägg gällande kostnadseffektivitet för undersökning med Cone Beam Computed Tomography (CBCT). READ MORE
