The automatic identification system (AIS), despite its importance in worldwide navigation at sea, does not provide any defence mechanisms against deliberate misuse, e.g., by sea pirates, terrorists, business adversaries, or smugglers.Previous work has proposed an international maritime identity-based cryptographic infrastructure (mIBC) as the found
A blind intrapulse modulation recognition based on energy focusing efficiency test abc material was proposed, which can be used to estimate the modulation type under low signal to noise ratio (SNR) conditions.The observed signals were pre-processed by short time filter defined in frequency domain in order to improve the processing SNR.Then, energy
Differential Evolution(DE) is a widely used technique to tackle complex optimization problems owing to its easy-implementation and excellent performance, nevertheless, the inborn weakness of the crossover operation has not been solved even in the recent state-of-the-art DE algorithms.There are two commonly used crossover schemes in DE, the exponent
This paper describes a review of the research developed on the English Language Teaching Practicum (ELTP) as part of a doctoral study on the senses of the ELTP through the experiences and interrelations of the English language teaching practicum community (ELTPC): preservice teachers (PTs), school and university mentors, (SMs-UMs [1]) in the Colomb
