The estimation of statistical parameters for local alignment score distributions.
The distribution of optimal local alignment scores of random sequences plays a vital role in evaluating the statistical significance of sequence alignments. These scores can be well described by an extreme-value distribution. The distribution's parameters depend upon the scoring system employed and the random letter frequencies; in general they cannot be derived analytically, but must be estima...
متن کاملAlignment Using Distributions Of Local
We describe a framework for aligning images without needing to establish explicit feature correspondences. We assume that the geometry between the two images can be adequately described by an aane transformation and develop a framework that uses the statistical distribution of geometric properties of image contours to estimate the relevant transformation parameters. The estimates obtained using...
متن کاملEstimation Of Statistical Distributions For Modal Parameters Identified From Averaged Frequency Response Function Data
An algorithm is presented to estimate the statistical distributions of identified modal parameters based on the random errors associated with averaged frequency response function estimates. In this study the modal parameters are assumed to be random variables and the objective is to estimate their distribution statistics (e.g. mean and variance). The algorithm first uses a classical approach to...
متن کاملEnhancing Parallelism of Pairwise Statistical Significance Estimation for Local Sequence Alignment
Pairwise statistical significance (PSS) has been found to be able to accurately identify related sequences (homology detection), which is a fundamental step in numerous applications relating to sequence analysis. Although more accurate than database statistical significance, it is both computationally intensive and data intensive to construct the empirical score distribution during the estimati...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
