Optimization, system-specific

Products in Group 3 seem to us to represent the future of practical batch process control. In such systems, modern workstations perform the single-user functions (e.g control system design, set-up, and maintenance operator interface data collection historical reporting) for which they were designed, while powerful multitasking controllers perform actual control. As computer hardware and software standards continue to evolve toward distributed networks of processors optimized for specific kinds of tasks, such systems will, we feel, proliferate rapidly. [Pg.474]

It must be pointed out that formation and stabihzation of nanoparticles in reversed micelles are the result of a delicate equilibrium among many factors. In addition, lacking a general theory enabling the selection a priori of the optimal conditions for the synthesis of nanoparticles of a given material with the wanted properties, stable nanoparticles containing w/o microemulsions can be achieved only in some system-specific and experimentally selected conditions. [Pg.492]

There are more than 150 companies around the world that are marketing systems based on gasification concepts. Many of these are optimized for specific wastes or particular scales of dedicated energy production operations. They vary widely in the extent to which they are proven in operation. In addition, there are more than 100 facilities operating around the world. [Pg.338]

The volumetric activity of a (bio)catalyst can be enhanced by simple addition of more catalyst to a system. Specific activity, however, must be improved through optimization of the reaction conditions, or through variation of the structure of the carrier (Chapter 5) or even of the enzyme (Chapters 10 and 11). [Pg.31]

In general, standard methods applicable to a vast majority of compounds of interest to ensure throughput capabilities are critical for LC/MS screens. Although not optimized for specificity, standard conditions provide a systemic measure of control. This control results in data that has high quality, reliability, and comparability. With a strategic selection of compounds that have similar molecular weights, structural features, and chromatographic properties, the detection selectivity and precision are satisfactory for this particular type of analysis. [Pg.108]

Continuum solvation models consider the solvent as a homogeneous, isotropic, linear dielectric medium [104], The solute is considered to occupy a cavity in this medium. The ability of a bulk dielectric medium to be polarized and hence to exert an electric field back on the solute (this field is called the reaction field) is determined by the dielectric constant. The dielectric constant depends on the frequency of the applied field, and for equilibrium solvation we use the static dielectric constant that corresponds to a slowly changing field. In order to obtain accurate results, the solute charge distribution should be optimized in the presence of the field (the reaction field) exerted back on the solute by the dielectric medium. This is usually done by a quantum mechanical molecular orbital calculation called a self-consistent reaction field (SCRF) calculation, which is iterative since the reaction field depends on the distortion of the solute wave function and vice versa. While the assumption of linear homogeneous response is adequate for the solvent molecules at distant positions, it is a poor representation for the solute-solvent interaction in the first solvation shell. In this case, the solute sees the atomic-scale charge distribution of the solvent molecules and polarizes nonlinearly and system specifically on an atomic scale (see Figure 3.9). More generally, one could say that the breakdown of the linear response approximation is connected with the fact that the liquid medium is structured [105],... [Pg.348]

It would be difficult to define the ideal flue gas treatment system that would perform optimally for all boilers under all circumstances. However, given a boiler and its specific criteria, an optimal flue gas treatment system would possess as many of the positive aspects of the elements described above as possible. Research funding applied in this area to obtain this optimal system would be best spent by improving flue gas treatment system performance for as many boiler-site combinations as possible. Toward this end, processes that are most broadly applicable to problems currently associated with emissions control in coal-fired electric power generating facilities become important candidates for future research. [Pg.160]

Insufficient saline or detergent in wash buffer. High-sensitivity staining systems may reguire higher concentrations of saline or detergent in the wash buffer. Refer to the staining system specification sheetfor optimal formulation. 115-121... [Pg.140]

The primary intent of this work is to design, build and verify a system capable of accurately varying important system variables that are normally strictly monitored and controlled by the commercial electrolyzers containing the same PEME stack. The goal of the experimental characterization of the stack, under varying conditions and power, is to enable an optimized interconnection between the stack and RE source. Such a coupled system specifically designed with the RE source in mind would reduce the overall cost of independent stand alone systems and may eliminate the need for electrical storage components. [Pg.62]

Use resource optimization when you need to come up with solution ideas that provide higher value than those in existence today—or when you need to refine and optimize a specific solution design. The key is to make sure you list as many resources as possible within and outside your immediate system or sphere of focus. After this, you can use any number of idea-generation techniques to figure out how your available resources can be applied to your inventive problem. [Pg.77]

Conceptually, the problems associated with the optimization of specific mechanical properties by variations of structure and morphology are the same in rubber-filled systems, ass-bead filled systems and semicrystalline polymers. When the fracture properties are singled out, our understanding of the relationships between macroscopic failure and local failure is hampered by the limited knowledge of stress transfer in statistically nonhomogeneous structures. The increased use of composites theory and micromechanics to address these problems would appear to be appropriate. [Pg.157]
