to determine the non-bonded interaction energies between naphthalene and b12n12 nano ring in different orientations and distances, geometry of molecules with b3lyp method and 6-31g* basis set optimized. also reactivity and stability of naphthalene alone and in the presence b12n12 nano ring checked. then calculated the nbo, nmr, freq, nics and muliken charge of naphthalene atoms alone and in the...

The estimation of source motion parameters takes a considerable importance for many areas. Especially for underwater acoustic applications where a large amount of da ta is available. This paper deals with the estimation of source motion parameters directly from the spatio-temporal data. A general frame for a separate estimation of the spatial frequencies and spatial freq-rate is presented, avoi...

In the epidemiological world, we often encounter the following analytical question: is the relationship between exposure and outcome different for different strata? The Breslow-Day test (with or without the Tarone adjustment) can be used in PROC FREQ to assess homogeneity across a series of 2 x 2 tables, but what if your tables are not 2 x 2? One alternative is to fit a log-linear model to a k ...

In this paper, we implement the robust demodulator for mobile broadband satellite internet access systems. Especially, in order to achieve the good synchronization under very low SNR, a large frequency offset, and Doppler frequency offset with constraints of mobile satellite communication, we introduce the efficient carrier freq. offset estimating algorithm and the carrier phase estimating algo...

In clinical trial data analysis, one of the most commonly used method for the analysis of categorical data is the Binomial proportion and their confidence intervals. If the variable of interest is a dichotomous categorical one, i.e. a variable with two levels (e.g. Subjects with serious AEs/Subjects without any serious AEs) then Binomial proportions (or percentages) and their CIs (or %CIs) can ...

A detailed analysis of anomalies of metallic gratings is performed for a large interval of groove depths. Two types of zero of the zeroth diffraction order are distinguished: the Bragg type [Alta Freq. 38, 82 (1969)], exhibited in a Littrow mount for both TM and TE polarizations and localized for flat surfaces at negative imaginary infinity in the complex a plane of the sinus of angles of incid...

In clinical trials nonparametric analysis methods are sometimes used to assess the differences between treatment groups. Most people use either the NPAR1WAY procedure or the FREQ procedure to perform nonparametric analysis. However, no procedures currently exist within SAS software to produce a nonparametric estimate of the difference between treatment groups or a confidence interval to assess ...

ince the introduction of electronic pacemakers, S a number of previously unencountered arrhythmias are now seen freq~ently.'.~ Among those more commonly observed is &cia1 ventricular parasystole which occurs when normal A-V conduction is resumed in patients with k e d rate pacemaker units.8 Spontaneous ventricular parasystole is occasionally encountered in patients with supraventricular mechani...
