Ensemble forecasts of meteorological variables provided by numerical weather prediction NWP systems are becoming increasingly popular in several decision-making problems concerning social and economic issues, such as water resource management, power generation, and protection from natural hazards. Ensemble forecasts are operationally employed for producing probabilistic forecasts of weather variables by accounting for the main sources of uncertainty in NWP model output Buizza et al. The first main source of uncertainty is the error in the initial conditions, which is then amplified by the chaotic nature of the atmospheric processes. The second source of uncertainty is related to the errors introduced by the imperfection of the model formulation of the atmospheric processes, which also affects the forecasts at all lead times Nicolis et al.

Filtering and prediction: a primer

Part of the Use R! Through this book, researchers and students will learn to use R for analysis of large-scale genomic data and how to create routines to automate analytical steps. The philosophy behind the book is to start with real world raw datasets and perform all the analytical steps needed to reach final results.

Though theory plays an important role, this is a practical book for advanced undergraduate and graduate classes in bioinformatics, genomics and statistical genetics or for use in lab sessions. This book is also designed to be used by students in computer science and statistics who want to learn the practical aspects of genomic analysis without delving into algorithmic details.

Chapters show how to handle and manage high-throughput genomic data, create automated workflows and speed up analyses in R. A wide range of R packages useful for working with genomic data are illustrated with practical examples. In recent years R has become the de facto tool for analysis of gene expression data, in addition to its prominent role in the analysis of genomic data.

Benefits to using R include the integrated development environment for analysis, flexibility and control of the analytic workflow.

At a time when genomic data is decidedly big , the skills from this book are critical. The key topics covered are association studies, genomic prediction, estimation of population genetic parameters and diversity, gene expression analysis, functional annotation of results using publically available databases and how to work efficiently in R with large genomic datasets.

Important principles are demonstrated and illustrated through engaging examples which invite the reader to work with the provided datasets. Step-by-step, all the R code required for a genome-wide association study is shown: starting from raw SNP data, how to build databases to handle and manage the data, quality control and filtering measures, association testing and evaluation of results, through to identification and functional annotation of candidate genes.

Similarly, gene expression analyses are shown using microarray and RNAseq data. He has extensive experience in analysis of livestock projects using data from various genomic platforms. His main research interests are in the development of computational methods for optimization of biological problems; statistical and functional analysis methods for high throughput genomic data expression arrays, SNP chips, sequence data ; estimation of population genetic parameters using genome-wide data; and simulation of biological systems.

Adaptive Kalman Filtering for Postprocessing Ensemble Numerical Weather Predictions

In statistics and control theory , Kalman filtering , also known as linear quadratic estimation LQE , is an algorithm that uses a series of measurements observed over time, containing statistical noise and other inaccuracies, and produces estimates of unknown variables that tend to be more accurate than those based on a single measurement alone, by estimating a joint probability distribution over the variables for each timeframe. The filter is named after Rudolf E. The Kalman filter has numerous applications in technology. A common application is for guidance, navigation, and control of vehicles, particularly aircraft, spacecraft and dynamically positioned ships. Kalman filters also are one of the main topics in the field of robotic motion planning and control and can be used in trajectory optimization.

In the following, we introduce typical workflows for three application scenarios, namely designing primers, analyzing primers, and comparing primer sets. The concept of coverage is of critical importance for multiplex PCR as it describes the number of templates that can be amplified with a set of primers. This package was specifically developed to enable researchers to evaluate the coverage of existing sets of primers as well as to design novel primer sets that maximize the coverage with a minimal number of primers. To provide a user-friendly tool, we created a Shiny app, which is available through the openPrimeRui package. The openPrimeR package enables the computation of the most important PCR-related physicochemical properties of primers to gauge whether a set of primers can provide high yields. The following list provides research questions that may be answered using openPrimeR:. If you would like to be able to access the immunoglobulin repository IMGT from the openPrimeR Shiny app, you should additionally fulfill the following dependencies:.

 - Он повернулся и направился к своему кабинету. Сьюзан открыла рот, но слова застряли у нее в горле. Хейл - Северная Дакота. Она замерла и непроизвольно задержала дыхание, чувствуя на себе взгляд Хейла. Сьюзан повернулась, и Хейл, пропуская ее вперед, сделал широкий взмах рукой, точно приветствуя ее возвращение в Третий узел. - После вас, Сью, - сказал. ГЛАВА 41 В кладовке третьего этажа отеля Альфонсо XIII на полу без сознания лежала горничная.

Запах одеколона и пота. Она инстинктивно отпрянула назад, застигнутая врасплох тем, что увидела. Из-за решетчатой двери кухни на нее смотрели. И в тот же миг ей открылась ужасающая правда: Грег Хейл вовсе не заперт внизу - он здесь, в Третьем узле. Он успел выскользнуть до того, как Стратмор захлопнул крышку люка, и ему хватило сил самому открыть двери. Сьюзан приходилось слышать, что сильный страх парализует тело, - теперь она в этом убедилась. Ее мозг мгновенно осознал происходящее, и она, вновь обретя способность двигаться, попятилась назад в темноте с одной только мыслью - бежать.

Она состояла из легких в использовании программ для домашнего компьютера, которые зашифровывали электронные послания таким образом, что они становились абсолютно нечитаемыми. Пользователь писал письмо, пропускал его через специальную программу, и на другом конце линии адресат получал текст, на первый взгляд не поддающийся прочтению, - шифр. Тот же, кто перехватывал такое сообщение, видел на экране лишь маловразумительную абракадабру. Расшифровать сообщение можно было лишь введя специальный ключ - секретный набор знаков, действующий как ПИН-код в банкомате. Ключ, как правило, был довольно длинным и сложным и содержал всю необходимую информацию об алгоритме кодирования, задействуя математические операции, необходимые для воссоздания исходного текста. Теперь пользователь мог посылать конфиденциальные сообщения: ведь если даже его послание перехватывалось, расшифровать его могли лишь те, кто знал ключ-пароль. АНБ сразу же осознало, что возникла кризисная ситуация.

 - Предупредите их о вирусе. Вы заместитель директора АНБ и обязаны победить. Стратмор медленно поднял голову и как человек, принимающий самое важное решение в своей жизни, трагически кивнул.

 Нет, вообще-то я… - Из туристического бюро. - Нет, я… - Слушайте, я знаю, зачем вы пришли! - Старик попытался сесть в кровати.
