3D imaging systems based on projectors and mobile phones

In this paper the multi-view 3D display system which includes the modules of capturing three-dimensional objects, image processing (creation of 3D image files) and display screen for the 3D image displaying based on integral imaging technology is developed. Large display screens using multi-projectors are created. Multi-projector system is used for improving the performance, such as viewing resolution, viewing angle, etc. Preliminary experimental results obtained using Full HD multi-projectors are discussed. 3D display based on mobile devices is also developed. 3D image files are created using 2D + depth files and 2D images captured at different view angles. Images on smartphones Sony 4K (resolution 3840 x 2160) and Samsung and LG (resolution 2560 x 1440) are demonstrated. © COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only

Reaction of 3-azidoisoxazoles with active methylene compounds

3-Azidoisoxazoles react with various active methylene compounds (malononitrile, ethyl cyanoacetate and ethyl acetoacetate) in the presence of base to give hybrid isoxazole–triazole molecules in good to nearly quantitative yields. © 201

Some effects of particle size on the sintering of titanium and a master sintering curve model

The press-and-sinter method of producing net shapes was applied to titanium alloys. The quantitative effects of the particle size of titanium and Ti-6Al-4V powders on the green and sintered densities were examined. Most powders were pressed at 100 to 800 MPa and sintered under vacuum at 1100 °C, 1200 °C, or 1300 °C for 2 hours. The green density was higher for coarser powders and for powders with a wider size distribution. The sintered density was higher for finer powders and for powders with a wider size distribution. The densification parameter was little affected by the compaction pressure but increased as the particle size was reduced. An empirical model of densification based on the master sintering curve approach was developed, with the activation energy for densification of titanium found to be approximately 160 kJ/mol
