In this paper we present an improve m e nt to o ur s e que nti al i nco re i m pl e mentation of a sparse Cholesky factorization based on a hypermatrix storage structure. We allow the inclusion of additional zeros in data submatrices to create larger blocks and in this way use more efficient routines for matrix multiplication. Since matrix multiplication takes about 90% of the total factorizati...

In the title complex, [Co(NCO)(2)(C(10)H(8)N(2))(2)], the Co atom is coordinated by four N atoms from two 2,2'-bipyridyl ligands and two N atoms from two cyanate anions in a distorted octa-hedral geometry. The Co atom lies on a twofold rotation axis. The average Co-N bond length is 2.126 (7) Å. Weak inter-molecular C-H⋯O inter-actions lead to the formation of a three-dimensional network.

1.1 Rationale Realizing the power of Network Centric Operations (NCO) depends directly not only on implementing weapon platform sophistication and lethality advances but also on how efficiently and effectively Units of Action (UofA) exploit information advantage to drive positive battlespace outcomes. We define information advantage following Driscoll and Henderson [1]: given existing intellige...

Necessary conditions of optimality (NCO) play an important role in optimization problems. They are the major tool to select a set of candidates to minimizers. In optimal control theory, the NCO appear in the form of a Maximum Principle (MP). For certain optimal control problems with state constraints, it might happen that the MP are unable to provide useful information — the set of all admissib...

Pet ownership has been shown to improve quality of life for older adults. The objective of this cross-sectional study was to compare older pet owners and older non-pet owners and assess differences between groups. This study was conducted on adults over 50 years of age, who owned either one cat or one dog versus nonowners based on age, race, gender, and education. Matched older pet owners (OPO)...

The main objective of this work was the incorporation of reactive isocyanate groups into chitin and chitosan in order to effectively use the products as reactive thickening agents in castor oil. The resulting gel-like dispersions could be potentially used as biodegradable lubricating greases. Three different NCO-functionalized polymers were obtained: two of them by promoting the reaction of chi...

Self-optimizing control is a promising method for selection of controlled variables (CVs) from available measurements. Recently, Ye et al. [2012] have proposed a globally optimal method for selection of self-optimizing CVs by converting the CV selection problem into a regression problem. In this approach, the necessary conditions of optimality (NCO) are approximated with linear combinations of ...

Novel bio-based polymer electrolyte was synthesized with LiClO4 as the main source of charge carrier. Initially, polyurethane-LiClO4 polymer electrolytes were synthesized via prepolymerization method with different NCO/OH ratios and labelled them as PU1, PU2, PU3 and PU4. Fourier transform infrared (FTIR) analysis indicates the co-ordination between Li ion and polyurethane in PU1. Differential ...

We investigated the nitrogen-hyperfine structure (hfs) and Stark effect in the rotational spectra of methyl isocyanate, CH 3NCO, and methyl isothio­ cyanate, CH 3NCS, by microwave Fourier transform (MWFT) spectroscopy. The rotational spectrum of methyl isocyanate was first measured and analyzed by Curl et al. [1] and Lett and Flygare [2]. More recently Koput [3] improved the analysis by the mod...
