to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...

In this study, seismic interferometry is investigated in which the Green’s function is estimated between two receivers by cross-correlation and integration over sources. For smoothly varying source strengths, the dominant contributions for the correlation integral come from the stationary phase directions in the forward and backward directions from the alignment of the two receivers. Gaussian b...

Disaster Management and current approaches in this field in one hand only has focused to physicalvulnerabilities and in the other hand has included consequential action to reduce vulnerability and improve physicalpreparation as well as resistance institutional insignificant during the disaster. Therefore, these approaches usually haveignored the capabilities and capacities of residents to reduc...

in financial distress studies selection of variable is commonly basedon the success of variables in variable sets employed in earlierbankruptcy studies, suggestions in the literature or an accompanyingdata reduction in a large set of variables. if seemingly different variablesets exhibit a strong relationship then heterogeneous variable setscapture common information. canonical correlation anal...

chickpea (cicer arietinum l.) is a native crop of asia which is grown worldwide including iran.in this study,different selection criteria including correlation,regression and path analysis were used to improve yield.the experimental design was split plot with rcbd replicated four times in which three sowing dates (5 january,4 february,and 5 march) were used in main plots and four genotypes;two ...

during the past decade, the world economic forum has published its annual reports in which the global competitiveness index is included. this paper aims to investigate the key factors for achieving an innovation-driven economy. in this paper, we used partial canonical correlation analysis (pcca) to examine the relationships between key pillars in “efficiency enhancers” and “business sophisticat...

In order to evaluate the genetic variation in Iranian summer savory accessions, different accessions were analyzed using multivariate and univariate analysis. Results indicated that there were significant differences in some traits. The mean comparison analysis using least significant difference (LSD) test revealed significant differences among the accessions understudy. In this regard, the hig...

A new approach for frequency analysis of recorded signals and readout the frequency of harmonics is presented in the paper. The main purpose has been achieved by the cross-correlation function and Hilbert transform. Using the method presented in the paper, there is another possibility to observe and finally to identify single harmonic apart from commonly used Fourier transform. Identification o...

This paper presents a simple formula relating multipath angular spread to small-scale fading statistics. This formula is then applied to nd an approximate spatial cross-correlation function for received voltage envelopes. The analytical approach is compared to 67 cross-correlation functions simulated with non-omnidirectional multipath. The equations in this paper provide insight for applying sp...
