Dynamic WIFI Fingerprinting Indoor Positioning System [PDF]
A technique is proposed to improve the accuracy of indoor positioning systems based on WIFI radio-frequency signals by using dynamic access points and fingerprints (DAFs). Moreover, an indoor position system that relies solely in DAFs is proposed.

Comparing Combinations of Linear and Nonlinear Feedback Terms for Ship Motion Control
In this article, combinations of linear and nonlinear feedback terms are investigated for 3 degrees-of-freedom pose and velocity control of ships. Nonlinear control algorithms that are found in the literature often have linear feedback terms, which ...

Application of an on-line trainning predictor/controller to dynamic positioning of floating structures [PDF]
An on-line training functional-link neural network predictor/controller for dynamic positioning of water surface structures is described in this paper. To develop a neural network for time-evolving systems, the deterministic on-line training model in a ...

The applications of a time-domain fuzzy logic controller for dynamic positioning of floating structures [PDF]
In this paper, a fuzzy logic controller for dynamic positioning of floating structures in deep water is presented. The core of the fuzzy controller is a set of fuzzy associative memory (FAM) rules that correlate each group of fuzzy control input sets to ...

Dynamic Positive Equilibrium Problem [PDF]
The Dynamic Positive Equilibrium Problem (DPEP) is a methodology for dealing with time series about economic agents' decisions, regardless of the amount of available information. The approach is articulated in three phases, as in the static counterpart Symmetric Positive Equilibrium Problem (SPEP), with the variant that it must be preceded by the ...

YDD-SLAM: Indoor Dynamic Visual SLAM Fusing YOLOv5 with Depth Information
Simultaneous location and mapping (SLAM) technology is key in robot autonomous navigation. Most visual SLAM (VSLAM) algorithms for dynamic environments cannot achieve sufficient positioning accuracy and real-time performance simultaneously.
