Validation Methods For Reflection Factor High Frequency

islanding detection methods for microgrids

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...

High Order Methods for High-Frequency Scattering Applications

High Frequency Acoustic Reflection and Transmission in Ocean Sediments

Task 1: In this effort, we developed a model of acoustic wave interaction with sand grains that included partitioning of wave energy into the rotational degrees of freedom of the sand grain. This model provides a physical explanation of the low frequency sound speeds measured at SAX99 and SAX04 which were found to be significantly below the Wood’s equation prediction. This effort was led by Nic...

Data Validation of High - Frequency Data : Time - Point - , Time - Interval - , and Trend - Based Methods

Real-time systems for monitoring and therapy planning, which receive their data from on-line monitoring equipment and computer-based patient records, require reliable data. Data validation has to utilize and combine a set of fast methods to detect, eliminate, and repair faulty data, which may lead to life-threatening conclusions. The strength of data validation results from the combination of n...
