Accuracy improving

Database development can be accelerated and its accuracy improved by first creating detailed equipment and process information sheets that fully describe each machine and system to be monitored. 

The Karl Fischer procedure has now been simplified and the accuracy improved by modification to a coulometric method (Chapter 14). In this procedure the sample under test is added to a pyridine-methanol solution containing sulphur dioxide and a soluble iodide. Upon electrolysis, iodine is liberated at the anode and reactions (a) and (b) then follow the end point is detected by a pair of electrodes which function as a biamperometric detection system and indicate the presence of free iodine. Since one mole of iodine reacts with one mole of water it follows that 1 mg of water is equivalent to 10.71 coulombs. 

The numerical accuracy of simulations performed using this model is affected by several factors. These include a) the degree of triangulation, b) the number of marching steps taken along the flow direction and c) the order of the polynomial basis function. Numerical accuracy improves as a, b and c increase, however the computational time can become excessive. Therefore, it was necessary to quantitatively determine the effects of these variables on numerical accuracy. 

The use of fundamental parameters is attractive for various reasons. They impose fewer restrictions on the number of standards required for analysis. This simplifies the standardisation protocol for maintaining a XRF system, and permits greater flexibility in dealing with different types of materials. Inten-sity/concentration algorithms of the fundamental type, i.e. without recourse to the use of standards, have gradually developed [238-240] and are now widely available [241]. Functionality and quality of XRF software have reached a very high level, with a large variety of evaluation procedures and correction models for quantitative analysis, and calculation of fundamental parameter coefficients for effective matrix corrections. Nevertheless, there is still a need for accuracy improvement of fundamental parameters, such as the attenuation functions. 

As a prescription drug for the treatment of ADHD, amphetamines have been shown to increase performance accuracy, improve short-term memory, improve reaction time, aid in mathematical computation, increase problem-solving abilities in games, and help individuals concentrate.

Normally, for mixtures containing 50% of each component the minimum value of kjjk is about 4, and the accuracy improves as the ratio [B]q/[A]o increases. In the graphical-extrapolation method, because the reactions must be carried nearly to completion, it is important that they be irreversible or have large equilibrium... 

The modem era of hydrate research is marked by the industrial adoption of the van der Waals and Platteeuw statistical thermodynamics model for the hydrate phase. The spectroscopic measurement of the hydrate phase, abetted with molecular simulation, led to accuracy improvements, and industrial applications to energy, seafloor stability, and climate change. With the above historical advances, consider modem thermodynamics of the hydrate phase itself. 

According to the initial optimization concept, this technique launches a set of parametric expressions for the differential operators, whose evaluation is based on proper error estimators [59]. What is actually desirable — yet analytically not feasible — for these estimators is that their dependence on frequency and propagation angle should resemble that of the true dispersion error. Hence, an expansion of these expressions in terms of basis angular functions is performed, which enables the accuracy improvement regardless the direction of propagation. Depending... 

The investigation of the aforementioned algorithm has shown that further accuracy improvements may be accomplished by the introduction of additional degrees of freedom. In view of this observation, an enhanced operator with optimal stability can be constructed. 

Important questions of metal adsorption at ionic metal oxides are (i) preferred adsorption sites (ii) strength and nature of metal-support interactions on regular and defect-rich surfaces (iii) charge redistribution between deposits and supports (iv) geometric and electronic structure as well as magnetism of small metal particles and deposition-induced alteration of these features (v) implications for the reactivity. We will also discuss accuracy improvements due to more precise xc functionals as well as more realistic cluster models of oxide supports. 

We used the DFT method which is fast, can handle large compounds and yield reasonably accurate energies. When combined with isodesmic work reactions we showed that the accuracy improves significantly and the results become suitable for... 

While direct measurement of PA and GB via the reactions shown above is practically impossible, these values have been estimated, with the accuracy improving with advances in chemical instrumentation. In the early twentieth century, Bom-Haber thermodynamic cycles were employed to estimate proton affinities. As with all approaches based on thermodynamic cycles (Section 5.3.2), uncertainties in the data used to construct a cycle propagate to the calculated values (in this case the proton affinity). 

In EMM, microtool surface finish is very important since it directly affects the mechanical strength of the tool [33] as well as machining accuracy. Therefore, precise microtools of micron scale size with a good surface quality are preferred while fabricating microfeatures like microhole, microgrooves, 3D cavities, and complex profiles. Microtools are generally fabricated in situ in an EMM setup or fabricated by other methods and are used in EMM. Machining accuracy improves with a reduction in... 

Nevertheless the quality of the observation of primary interest for high-precision applications, the carrier phase, was not significantly improved since the early days of the first geodetic GPS receiver, the Macrometer. Accuracy improvements are to y expected... 

When we switched to our new demand management solution, we saw our forecast accuracy improve immediately. We also saw service levels take off in a positive way and our inventories decreased. We exceeded our original projections the accuracy is driven by a change from a 50,000-foot view of forecasts to a more detailed look. Now we can talk about a particular deal with a retailer and know what kind of lift is generated and then that drives the supply chain. There is no second-guessing, said a demand planner at a food and beverage company.
