1. 16. 3D Electron crystallography : Real space reconstruction and reciprocal space tomography

   Författare :Daliang Zhang; Xiaodong Zou; Douglas L. Dorset; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; Electron microscopy; Porous materials; Chemistry; Kemi; Structural Chemistry; strukturkemi;

   Sammanfattning : Electron crystallography is an important technique for studying micro- and nano-sized materials. It has two important advantages over X-ray crystallography for structural studies: 1) crystals millions of times smaller than those needed for X-ray diffraction can be studied; 2) it is possible to; focus the electrons to form an image.

   Sammanfattning : Building Information Modelling (BIM) has prominently innovated and digitalized buildingenvironment through digital representation of buildings, lifecycle process and managementfor involved actors. Rapidly developed from Geographical Information System (GIS) domain,three-dimensionally (3D) GIS provides powerful and comprehensive functions of planning,modelling, visualizing and analyzing 3D geodata in large scale.

   Sammanfattning : Continuous scaling of transistor dimensions has been in the heart of semiconductorindustry for many years. Recently the scaling has been enabled by various performance boosters which resulted in increased processing complexity and cost, forcing the chip manufacturers to look for some alternative solutions.

5. 19. Testing and analysis of composites with 3D woven reinforcement

   Författare :Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D weave; finite element; manufacturing; yarn path; weaving; failure criteria; mechanical testing; 3D väv; finita element; tillverkning; trådbanor; vävning; brottkriterier; mekanisk provning; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. LÄS MER

7. 20. The Use of 2D and 3D Displays in Military Settings

   Författare :Patrik Lif; Leo Poom; Kip Smith; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; visuell perception; 3D; displays; spatial cues; Psychology; Psykologi;

   Sammanfattning : The purpose of this thesis is to evaluate the possibilities of using 3D perspective displays in different military settings, and to illustrate the limitations of 3D displays, that is, when 2D displays are to be preferred. More specifically, this thesis explores (a) readability during vibrations, (b) perception aspects on perspective aircraft displays, and (c) the value of spatial cues in 3D air traffic displays in military settings.
