Data trace

No overlap. Data trace update rate is the same as the block processing rate. This rate is governed by the physical requirements that are internally driven by the frequency range of the requested data. 

Figure 24.15 Single-sweep data traces of H2O absorption recorded in a hypersonic flow with an enthalpy of 10 MJ/kg. The panels shows the absorbance (as a function of laser frequency, cm ) near 1.400 pm (a) and 1.395 pm (6) recorded simultaneously. V = 4630T50 m/s Ttran.i = 561 15 K Ph20,i = 0.43 0.03 Torr Ttran,2 = 544 35 K and Ph20,2 = 0.45 0.06 Torr...

An interesting method of fitting was presented with the introduction, some years ago, of the model 310 curve resolver by E. I. du Pont de Nemours and Company. With this equipment, the operator chose between superpositions of Gaussian and Cauchy functions electronically generated and visually superimposed on the data record. The operator had freedom to adjust the component parameters and seek a visual best match to the data. The curve resolver provided an excellent graphic demonstration of the ambiguities that can result when any method is employed to resolve curves, whether the fit is visually based or firmly rooted in rigorous least squares. The operator of the model 310 soon discovered that, when data comprise two closely spaced peaks, acceptable fits can be obtained with more than one choice of parameters. The closer the blended peaks, the wider was the choice of parameters. The part played by noise also became rapidly apparent. The noisy data trace allowed the operator additional freedom of choice, when he considered the error bar that is implicit at each data point. 

Fig. 19 Deconvolving s(x) = sinc(jc) and s(x) = sinc2(x) convolved data. Trace (a) is the original spectrum o(x), trace (b) the result of convolving with an eight-point sine function, trace (c) the result of unconstrained deconvolution using the same sine function for just 10 iterations. Trace (d) is the result of 100 iterations using zero clipping. Trace (e) is the original spectrum convolved with an 8 /T-point sine-squared function, trace (f) the result deconvolving trace (e) with the same sine-squared function for 100 iterations using the Jansson-type relaxation function r k)[oik X)(x)].

Fig. 2. Plot of homogeneous relaxation rate, % versus number density for neat iodine vapor, Results for 37 measurements are shown. Horizontal error bars indicate uncertainty in the absorption cross section of iodine, vertical error bars indicate uncertainty in the exponential fitting routine. Dotted lines represent the 90% confidence interval based on a linear least squares fit. Inset is a typical PE data trace plotted on a logarithmic scale, This trace corresponds to a number density of 5x1023 m 3.

The raw data trace for a mixture of 6 standard polystyrene latex microspheres is shown in Figure 2. This separation was done in 20 minutes at 10,450 rpm. While particle size data in the first few minutes is difficult to quantitate accurately with the DCP, this separation demonstrates the resolution capability of the instrument. Figures 3-7 show typical raw data, and number, surface and weight differential and cumulative distribution plots produced by the data system along with the corresponding report. 

The advantages of this kind of organization system are clear. Any issues with accuracy of transcription are alleviated. Since peak tables are automatically extracted from the data traces, there is no need for cut-and-paste functions. However, the destination path must be set prior to the transfer, and also the proper integration thresholds must be configured. Data can be part of multiple optimization/screening waves at the same time. In addition, there are... 

Figures 10.8 and 10.9 are data traces showing TGS weight-loss curves for various polymers, including polyurethane foam.

The method is based on time delays. For instance, define a two-dimensional vector x(r) = (B(t). B(t -I- t)) for some delay T > 0. Then the time series B t) generates a trajectory x(r) in a two-dimensional phase space. Figure 12.4.2 shows the result of this procedure when applied to the data of Figure 12.4.1, using t = 8.8 seconds. The experimental data trace out a strange attractor that looks remarkably like the Rdssler attractor ... 

A quasi steady-state solution for the tracer distribution in a soilpolutnn has been developed for the inlet boundary concentration being a constant plus a Sinusoidal component. Then an unsteady state solution for tracer distribution a soil column was developed for the same inlet boundary condition as above. The unsteady-state tracer concentration distribution applies to the section of a soil column that still remembers the initial condition. The two solutions may be applicable to those planning experiments to measure parameters such as the dispersion coefficient from tracer tests. A sinusoidal loading of tracer at the inlet boundary may enable one to obtain repeated data traces at the column outlet as part of an extended experiment. Continued collection of tracer concentration vs. time data at the column outlet over a number of periods would enable one to collect data from repeated experiments, for each period of the sine wave would represent another experiment. This should enable one to obtain more replicates of data to improve statistical estimates of the dispersion coefficient than could be obtained by experimental methods that use a slug loading or a step change of concentration at the column inleL"...

Comparison of the modeling results using the desorption parameters derived by the TTPD method (solid trace B) and using initial values (dashed trace C). The experimental data (trace A) obtained by Muhler et al. [6] are shown in the inset reactor volume 0.3 cm , reactor pressure 760 torr, inlet flow rate 100 Nml/min, heating rate 6 K/min, number of sites 2.1-10 .

Analysis. The time series data traces for each meter should, via the above decomposition for Om, indicate valid expectation data to corroborate meter well-being during round robin tests as well as longterm longevity. These results are critical to show what type of and perhaps when refurbishments are needed to keep the artifacts in proper condition.

RuPcY and Co and Mn-tetraphenylporphyrin Y (tePPorY) have been examined as mimics for methane oxygenase (27). Table 5 gives relevant data. Traces of methanol seem to be obtained from methane but at reaction temperatures (above 573 K) where the stability in time of the catalysts was very limited as evidenced by the large CO2 yield. Personally, we have not yet been able to reproduce these data.

The Working Party and other groups consider not only the application of the relevant law but also a variety of non-legal solutions which might assist in the resolution of some of the difficulties. Problems with the divergence of definition of personal data may be resolved if identification of specific individuals is never possible from data traces, i.e. the promotion of anonymity on the Internet. An earlier recommendation of the Working... 

It is generally accepted that lead in whole blood is distributed unevenly between the erythrocytes and plasma or serum, with the former binding virtually all of the total blood lead content based on long-known data tracing mainly to the 1970s (see previous chapters). Little difference in lead concentration is typically seen between serum and plasma, about 1% of the total amount in blood. At PbB levels >25 p.g/dl, the equilibrium concentration in plasma as a fraction of total PbB rises in a curvilinear fashion (DeSilva, 1981 Manton and Cook, 1984). 

A trace is a sequence of instructions executed by a program on some given input data. Traces are often used by human beings to explain an existing algorithm. For instance, the protocol of using a telephone is easily described by sample traces.
