REAL TIME KINEMATIC (RTK) HEAVE AS A REPLACEMENT OF MOTION REFERENCE UNIT (MRU) HEAVE IN HYDROGRAPHIC SURVEYING WORKS

Real Time Kinematic (RTK) heave as a replacement of Motion Reference Unit (MRU) heave in hydrographic surveying works

Heave is one of the major contributors to errors in water depth measurements.Motion Reference Unit (MRU) measures the heave signal with high-level accuracy as well as other ship motions.Unfortunately, MRU has been reported to have some of drawbacks such as; heave drift error, influence of ship motion dynamic, In addition to its very expensive price

The Danger Theory: Twenty Years Later

The self-nonself theory has dominated immunology since the 1950s.In the 1990s, Matzinger and her colleagues suggested a new, competing theory, called the danger theory.This theory Doll house furniture has provoked mixed acclaim: enthusiasm and criticism.Here we assess the danger theory vis-à-vis recent experimental data on innate immunity, tra

Greedy Action Selection and Pessimistic Q-Value Updating in Multi-Agent Reinforcement Learning with Sparse Interaction

Although multi-agent reinforcement learning (MARL) is a promising method for learning a collaborative action policy, enabling each agent to accomplish specified tasks, MARL has a problem of exponentially increasing state-action space.This state-action space can be dramatically reduced by assuming sparse interaction.We previously proposed three meth
