Where f denotes Doppler Frequency, τ denotes multipath propagation delay, S (f,τ) denotes the scattering function. In a Power Delay Profile plot, the signal power of each multipath is plotted against their respective propagation delays. A sample power delay profile plot, shown below, indicates how a transmitted pulse gets received at the receiver with different signal strength as it travels thr...

The paper deals with the issues of energy saving in railway section, which has a tunnel double longitudinal slope, limits capacity trains due to decrease rated voltage by more than 10%, negatively affects thermal and transient electromechanical processes. practicality regulation using existing installation series compensation is shown; it proposed use an additional parallel reactive power compe...

A G × E performance (interaction, profile) plot for showing genotype-by-environment data is discussed. Three versions of such a plot are compared: the regular performance plot; the performance plot based on coded data (environment-centered performance plot), in which the environment means of a trait are subtracted from data; and the performance plot based on data standardized in environments (e...

Studying on spatial and temporal variation in soil organic carbon (SOC) is of great importance because of global environmental concerns. Tillage-induced soil erosion is one of the major processes affecting the redistribution of SOC in fields. However, few direct measurements have been made to investigate the dynamic process of SOC under intensive tillage in the field. Our objective was to test ...

BACKGROUND Until now, no kinetic model was described for the oncologic tracer [18F]fluoromethylcholine ([18F]FCho), so it was aimed to validate a proper model, which is easy to implement and allows tracer quantification in tissues. METHODS Based on the metabolic profile, two types of compartmental models were evaluated. One is a 3C2i model, which contains three tissue compartments and two inp...

UNLABELLED MatrixPlot is a program for making high-quality matrix plots, such as mutual information plots of sequence alignments and distance matrices of sequences with known three-dimensional coordinates. The user can add information about the sequences (e.g. a sequence logo profile) along the edges of the plot, as well as zoom in on any region in the plot. AVAILABILITY MatrixPlot can be obt...

Interval estimates for nonlinear parameters using the linear approximation are sensitive to parameter curvature effects. The adequacy of the linear approximation (Wald) interval is determined using the nonlinearity measures of Bates and Watts (1980), and Clarke (1987b), and the profile t plots of Bates and Watts (1988). These curvature measures and profile t plot calculations are . e ® implemen...

Figure 2 shows a plot of the associated MWR-retrieved water vapor (WV) from (1) an iterative or minimization approach based on a single nearby (in time) radiosonde profile and using the Liebe 87 absorption model, (2) the standard ARM statistical retrieval (data straight from the archive), and (3) the MWR profile (PROF) value-added procedure. The MWR PROF retrieval (one of the ARM standard value...
