Drop plate technique has a priority and preference compared with the spread plate procedure, because of less time, quantity of media, effort requirement, little incubator space, and less labor intensive. The objective of this research was to compare the accuracy and fidelity of drop plate method vs. spread plate method by parametric and nonparametric statistical tests. For bacterial enumeration...

داده های فضایی در بررسی های علوم محیطی مانند هواشناسی، محیط زیست، زمین شناسی و اقیانوس شناسی در طول زمان نیز به یکدیگر وابسته ان. تحلیل این گونه داده ها مستلزم تعیین ساختار همبستگی فضایی-زمانی آن ها از طریق کواریانس است. در دو دهه اخیر بررسی های زیادی برای مدل بندی و تحلیل چنین داده هایی صورت گرفته است. در این پایان نامه روش رگرسیون چندک بیز برای تحلیل داده های فضایی-زمانی ارائه شده است .
We introduce a family of multiscale, orientation-selective, non-parametric features (“ranklets”) modelled on Haar wavelets. We clarify their relation to the Wilcoxon ranksum test and the rank transform and provide an efficient scheme for computation based on the Mann-Whitney statistics. Finally, we show that ranklets outperform other rank features, Haar wavelets, SNoW and linear SVMs (based on ...
The study of meteorological characteristics and its variability is important in assessing the climate change impacts for water resources management. Trend analysis of hydrological and meteorological time series is a method for determining the change in climate variables that is performed with different parametric and non-parametric methods. In this research, the annual, seasonal and monthly tr...
in this study 485 specimen of garra rufa (heckel, 1843) from 29 populations from six river systems and basins including tigris, karkheh, karun, persis (helleh and mond), hormuz and maharlu were collected by a 5mm mesh sized seine net, anesthetized in 1% clove oil solution, fixed in 10% formalin and transferred to the laboratory for further investigations. some 28 morphometric, 25 morphometric p...
