Several modes of measurement are used in the tomographic system. The most rapid one is applied as an estimation mode, the estimation error being a factor of 1.5 to 2 higher than that one of the conventional mode. With the estimation mode defective section can be detected rapidly and then they can be quantitatively investigated in detail using other modes... 

Researchers must be particularly cautious when using one estimated property as the input for another estimation technique. This is because possible error can increase significantly when two approximate techniques are combined. Unfortunately, there are some cases in which this is the only available method for computing a property. In this case, researchers are advised to work out the error propagation to determine an estimated error in the final answer. 

Ideally, the results should be validated somehow. One of the best methods for doing this is to make predictions for compounds known to be active that were not included in the training set. It is also desirable to eliminate compounds that are statistical outliers in the training set. Unfortunately, some studies, such as drug activity prediction, may not have enough known active compounds to make this step feasible. In this case, the estimated error in prediction should be increased accordingly.

An analytical method for the prediction of compressed liquid densities was proposed by Thomson et al. " The method requires the saturated liquid density at the temperature of interest, the critical temperature, the critical pressure, an acentric factor (preferably the one optimized for vapor pressure data), and the vapor pressure at the temperature of interest. All properties not known experimentally maybe estimated. Errors range from about 1 percent for hydrocarbons to 2 percent for nonhydrocarbons. 

Valid emission factors for each source of pollution are the key to the emission inventory. It is not uncommon to find emission factors differing by 50%, depending on the researcher, variables at the time of emission measurement, etc. Since it is possible to reduce the estimating errors in the... 

Fluid viscosity—For Newtonian fluids (a constant viscosity at all impeller speeds) approximate viscosities up to 5,000 centipoises are satisfactory. Above 5,000 centipoises. estimating errors of 20 to 50% can mean undersizing or oversizing the agitator. 

In refined structures at high resolution (around 2 A) there are usually no major errors in the orientation of individual residues, and the estimated errors in atomic positions are around 0.1-0.2 A provided the amino acid sequence is known. Hydrogen bonds both within the protein and to bound ligands can be identified with a high degree of confidence. 

X-ray structures are determined at different levels of resolution. At low resolution only the shape of the molecule is obtained, whereas at high resolution most atomic positions can be determined to a high degree of accuracy. At medium resolution the fold of the polypeptide chain is usually correctly revealed as well as the approximate positions of the side chains, including those at the active site. The quality of the final three-dimensional model of the protein depends on the resolution of the x-ray data and on the degree of refinement. In a highly refined structure, with an R value less than 0.20 at a resolution around 2.0 A, the estimated errors in atomic positions are around 0.1 A to 0.2 A, provided the amino acid sequence is known.

Table 4 Tight-binding vacancy formation energies compared to first-principles calculations and experiment. Energies were computed using a 108 atom supercell. The experimental column shows a range of energies if several experiments have been tabulated. Otherwise the estimated error in the experiment is given.

If a particle A must know B s total information content before colliding, the collision process must be delayed until A has full access to that information. However, such a delay is consistent neither with classical nor quantum mechanics, Minsky instead suggests that the collision proceeds immediately, but with the particles both working with less than all the information that is classically required i.e, the incoming particles momenta are estimated. Outgoing momenta are determined via conventional classical rules, but, because of the estimation errors, each scattered particle leaves behind a receipt recording how much momentum was really taken away in the process. Receipts not only mark prospective event-locations at which future collisions might take place, but harbor information that can be used to estimate new real momenta. 

The experimental error was estimated as 1-4% in k (208). In Figure 11, the more skeptical value of 5% is shown in Figure 12, the corresponding errors in E and log A are pictured at the point 29. In the coordinates logkj versus log ki, the correlation coefficient can be computed as r =. 9919 or. 9991, with or without the point 4, respectively. The corresponding standard deviations from the regression lines are. 068 and. 022 log unit, respectively. Their difference justifies the exclusion of point 4 the latter value compares favorably with the estimated error of 5% in k =. 021 log unit. 

In the expression for AHfso, the term -RT drops out. The values of ASjso are then obtained from AHjso and AG. The relationship of isokinetic and unconstrained activation parameters is shown in Figure 22 (see Table I). The computed values (57) of AH and AS are shown together with their estimated errors, which are mutually dependent. The points can thus only move along a... 

Comment Instead of calculating a critical tc and comparing it to the experimental one, the experimental t is converted into an estimated error probability, which is then checked against a preset value, e.g., 0.05. The medical and social science communities prefer using the second approach. This algorithm is theoretically underpinned. 

Error calculations based on a 5% error in the measured R, values. Calculated from Eq. 5/ and the py values given in Ref. 85. Estimated error of 0.01 A. Only the average value could be determined for thqse protons, because their resonances were not separately resolved for the isotopomers 44c and 44d. Calculations based on the assumption that = p2t = Ps.sc = Pi,3 - From Refs. 78 and 85. 

Given a choice for G, the question is, if and under which conditions the model, g(x), converges to g (x) as the number of points increases to infinity, or, in other words, if it is possible to completely eliminate the estimation error. The answer will emerge after addressing the following questions. 

The equation assumes that the cost of estimation error for an estimate based on n replicate samples is proportional to the mean squared error... 

Note that bias does not affect the optimum n (since replication does not reduce bias). The major difficulty with applying this model lies In Identifying the cost of estimation error, 2 ... 

Even If the cost of estimation error cannot be quantified as this model requires, effective allocation of resources may be possible when detailed knowledge of sources of variation Is available. In this case, a replication strategy can be based on variance component and cost Information. For example, consider the problem of deciding how many samples to collect and how many analyses to perform on each sample Let...
