The detection and mitigation of Non-Line-of-Sight (NLOS) signals are crucial for achieving the full potential UWB-based indoor positioning. In dense multipath industrial environments, it was seen that using power characteristics received signal to identify NLOS conditions is effective when tracking stationary objects but insufficient mobile object tracking. Hence, machine learning classifiers utilizing Multi-Layer Perceptron (MLP) Boosted Decision Trees (BDT) were developed improve...

In addition, some attacks based on physical access to phone like smudge All these have reminded current pay more attention for security installing anti-malware software defend against malicious apps,...
Abstract Background Mammalian antimicrobial peptides (AMPs) are effectors of the innate immune response. A multitude signals coming from pathways mammalian pathogen/pattern recognition receptors and other proteins affect expression AMP-coding genes (AMPcgs). For many AMPcgs promoter elements transcription factors that control their tissue cell-specific have yet to be fully identified characterized. Results Based upon RIKEN full-length cDNA public sequence data derived human, mouse rat, we...
A typical wireless Electric Vehicle (EV) charging system consists of a transmitting coil at the station and receiving in vehicle.
