ACM Transactions on Mathematical Software, 2009
Bundle adjustment constitutes a large, nonlinear least-squares problem that is often solved as the last step of feature-based structure and motion estimation computer vision algorithms to obtain optimal estimates. Due to the very large number of parameters involved, a general purpose least-squares algorithm incurs high computational and memory storage ...

Formation mechanism of SBA-3, SBA-15 and SBA-16 type mesoporous silica in acidic solutions
2007Abstract The evolution of the species in acidic solutions, prepared from tetraethoxysilane (TEOS), surfactant (Cetyltrimethylammonium bromide, Pluronic P123 or Pluronic F127) and HCl, was followed by visual observation and Dynamic Light Scattering (DLS) measurements between 25 and 90°C until their precipitation.

Synthesis and Characterization of Molecular Sieve SBA-15 and Catalysts Co/SBA-15 and Ru/Co/SBA-15
Materials Science Forum, 2014A series of mesoporous materials have been synthesized in an acid medium, with various structures, such as SBA-15. These materials have many properties which make them potential catalysts. Among these we highlight their high surface areas and pore walls relatively thick, resulting in a greater hydrothermal stability. This work aims at the synthesis and

The System for Business Automation (SBA)
Proceedings of the 1976 conference on Data : Abstraction, definition and structure -, 1976The system for business automation (SBA) is a system within which application experts—nonprogrammers—can describe and execute their applications on a computer. The user of SBA views his application as manipulation of information in two-dimensional pictures of tables, business forms, and reports on a display terminal.

Recrystallisation of SBA-15 into ZSM-5/SBA-15 composites
2005Micro/mesostructured ZSM-5/SBA-15 composites were prepared by secondary crystallisation of SBA-15 impregnated with a solution of tetrapropylammonium hydroxide and sodium aluminate. The samples were characterised by X-ray diffraction (XRD), nitrogen sorption, infrared spectroscopy (FTIR) and scanning electronic microscopy (SEM).
