Microgrids (MGs) offers grid-connected (GC) and islanded (ID) operational modes. However, these dynamic modes of operation pose different microgrid protection challenges. This paper presents a new method for MGs based on discrete one-dimensional recursive Median filter (1-DRMF). In the first step, 1-DRMF is applied measured current signal every single phase individually targeted feature extract...

Collaborative filtering is a widely used and proven method of building recommender systems that provide personalized recommendations on products or services based on explicit ratings from users. Recommendation accuracy becomes an important factor in some e-commerce environments (such as a mobile environment as a result of limited connection time and device size). As user preferences change over...

Abstract A new histogram-based robust filter developed for noise reduction of digital elevation model data is presented. When large percentage points in matrices are contaminated with outlier noise, the process can give better results than traditional median filtering, if elements a potentially higher chance being eliminated by weighting from input dataset before value calculated. However, on s...

Underwater acoustic monitoring systems record many hours of audio data for marine research, making fast and reliable non-causal signal detection paramount. Such detectors assist in reducing the amount labor required annotations, which often contain large portions devoid signals. Cetacean vocalization based on spectral entropy is investigated as a means discovery. Previous techniques using (SE) ...
