Measurement-based optimization schemes have been developed to deal with uncertainty and process variations. One of the methods therein, labeled NCO tracking, relies on appropriate parameterization of the input profiles and adjusts the corresponding input parameters using measurements so as to satisfy the necessary conditions of optimality (NCO). The applicability of NCO-tracking schemes has bee...

In order to determine the suitability of varieties for the Pongola area, two trials were established at the SASA Experiment Substation at Pongola, one harvested every spring and the other every autumn. Random samples of cane stalks were taken prior to harvesting and the ERS % C was determined. Using these data it was possible to study the variation in ERS % C with crop age and time of year. It ...

Field trials were used to investigate the phytotoxicity of foliar sprays of 2,4-D amine to sugarcane. Yield losses of variety NCo 376 resulted from band sprays when 3,3 kg ae/ha was sprayed onto plant or ratoon cane which had unfurled three or more leaves per shoot. The greater the foliar development of the crop at the time of spraying, the greater was the resulting crop loss. At similar stages...

Plans for NextGen include the implementation of Net-Centric Operations (NCO) as the underlying mechanism to more effectively manage National Air Transportation System (NAS) resources. NCO mechanisms will provide the means for all agents operating in the NAS to self-synchronize in the presence of changing situations and probabilistic forecasts. Applications of NCO in other domains (e.g. military...

[RhCl(NCO)(nbyl)(PR3)] (nbyl = σ-norbornenyl; NCO = quinoline-8-acyl; R = p-F-C6H4) (1) has been synthesized by the reaction of [Rh(nbd)Cl]2 (nbd = norbornadiene) with 2 equivalents of NCHO (quinoline-8-carbaldehyde) and 2 equivalents of PR3. Compound 1 has been fully characterized in solution and also in the solid state by X-ray diffraction. Compound 1 shows low stability in solution and under...

Click reactions have provided access to an array of remarkably complex polymer architectures. However, the term "click" is often applied inaccurately to polymer ligation reactions that fail to respect the criteria that typify a true "click" reaction. With the purpose of providing a universal way to benchmark polymer-polymer coupling efficiency at equimolarity and thus evaluate the fulfilment of...

There has been a longstanding interest in deriving conditions under which dynamic optimization problems are normal, that is, the necessary conditions of optimality (NCO) can be written with a nonzero multiplier associated with the objective function. This paper builds upon previous results on nondegenerate NCO for trajectory constrained optimal control problems to provide even stronger, normal ...

The coordination geometry of the Cd(II) atom in the title complex, [Cd(NCO)(2)(C(10)H(14)N(4))(2)](n) or [Cd(NCO)(2)(bimb)(2)](n), where bimb is 1,4-bis-(imidazol-1-yl)butane, is distorted octa-hedral with the Cd(II) atom located on an inversion center and connected to four N atoms from the imidazole units of four symmetry-related bimb ligands and two O atoms from two symmetry-related NCO(-) li...

A series of polyurethane elastomers based on an aliphatic diisocyanate and a polyether macroglycol was polymerized with various cross-link densities and OH/NCO ratios. Stoichiometries yielding between 8,600 and 12,900 gm/mole/crosslink and an OH/NCO ratio of 1.1 resulted in polymers with the low modulus, yet high strength and elongation necessary for maxillofacial applications.

Direct detection of (13)C can be advantageous when studying uniformly enriched proteins, in particular for paramagnetic proteins or when hydrogen exchange with solvent is fast. A scheme recently introduced for long-observation-window band-selective homonuclear decoupling in solid state NMR, LOW-BASHD (Struppe et al. in J Magn Reson 236:89-94, 2013) is shown to be effective for (13)C(α) decoupli...
