In order to detect and track multiple maneuvering dim targets in sensor systems, an improved dynamic programming track-before-detect algorithm (DP-TBD) called penalty DP-TBD (PDP-TBD) is proposed. The performances of tracking techniques are used as a feedback to the detection part. The feedback is constructed by a penalty term in the merit function, and the penalty term is a function of the pos...

Many elderly and physically impaired people experience difficulties when maneuvering a powered wheelchair. In order to provide improved maneuvering, powered wheelchairs have been equipped with sensors, additional computing power and intelligence by various research groups. This paper presents a Bayesian approach to robotic assistance for wheelchair driving, which can be adapted to a specific us...

Wireless sensor networks (WSN) depends on the algorithms and protocols for Communication and computation. In this paper, we implement sensors that sense the environment actively by emitting energy and measuring the reflected energy, a novel collaborative sensing scheme is used to sense multiple targets and high maneuvering targets in an energy efficient method. Joint sensing can increase the se...

The collision avoidance procedure of a ship can be divided into three categories: detects environment and accesses the degree of the collision risk; establishes navigation plan and executes a control command to perform the established plan; returns to her original path when collision risk disappears. We can obtain own ship’s speed and rudder angle to avoid the ship collision through the expert ...

The important field of research on ship operation is related to the high efficiency of transportation, the convenience of maneuvering ships, and the safety of navigation. This paper proposes an ontology-based fuzzy support agent for ship steering control and desires to testify the validity of the proposal by applying the fuzzy control model to the steering control system based on linguistic ins...

This paper describes a revolutionary, fully-integrated approach for modeling the noise characteristics of maneuvering rotorcraft. The primary objective of this effort is the development of a physics-based software tool that enables the design of quiet rotors without performance penalties. This tool shall accurately predict the rotorcraft flight state and rotor trim, the unsteady aerodynamic loa...

The design and simulation of an on-line algorithm which estimates the safe maneuvering envelope of aircraft is discussed in this paper. The trim envelope is estimated using probabilistic methods and efficient high-fidelity model based computations of attainable equilibrium sets. From this trim envelope, a robust reachability analysis provides the maneuverability limitations of the aircraft thro...

The problem of maneuvering target tracking has been studied in the field of the state estimation over decades. The Kalman filter has been widely used to estimate the state of the target, but in the presence of a maneuver, its performance may be seriously degraded. In this paper, to solve this problem and track a maneuvering target effectively, an intelligent Kalman filter (IKF) and an intellige...

Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...
