SYNTHESIS OF YTTRIUM AND CALCIUM STABILIZED ZIRCONIA BY CONTROLLED DOUBLE-JET PRECIPITATION

The work is aimed at obtaining yttrium and calcium stabilized zirconia with a spheroidal particle shape and a narrow particle size distribution. It was shown that the stabilizing com-ponents have a different effect on the morphology and particle size distribution of the obtained oxides

SYNTHESIS OF CdS FILMS ON GLASS BY THE AMMONIA-ALKALINE SCHEME

This work is aimed at finding optimal conditions for the synthesis of CdS films in order to obtain films of controlled thickness and high homogeneity. The presence of Cd(OH)2 in the synthesized films was revealed. The optimal parameters for the synthesis of CdS films are found

Proceedings of the second "international Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST'14)

The implicit objective of the biennial "international - Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST) is to foster collaboration between international scientific teams by disseminating ideas through both specific oral/poster presentations and free discussions. For its second edition, the iTWIST workshop took place in the medieval and picturesque town of Namur in Belgium, from Wednesday August 27th till Friday August 29th, 2014. The workshop was conveniently located in "The Arsenal" building within walking distance of both hotels and town center. iTWIST'14 has gathered about 70 international participants and has featured 9 invited talks, 10 oral presentations, and 14 posters on the following themes, all related to the theory, application and generalization of the "sparsity paradigm": Sparsity-driven data sensing and processing; Union of low dimensional subspaces; Beyond linear and convex inverse problem; Matrix/manifold/graph sensing/processing; Blind inverse problems and dictionary learning; Sparsity and computational neuroscience; Information theory, geometry and randomness; Complexity/accuracy tradeoffs in numerical methods; Sparsity? What's next?; Sparse machine learning and inference.Comment: 69 pages, 24 extended abstracts, iTWIST'14 website: http://sites.google.com/site/itwist1

INVESTIGATION OF THE CONTROLLED TWO-JET PRECIPITATION PROCESS OF HYDRATED ZIRCONIA

The controlled two-jet precipitation process of hydrated zirconia was studied. Particle size experimental information were analyzed using population balance. It was found that hydrated zirconia synthesized at pH = 3 and pH 5 has two populations, and at pH = 8 it has only one population
