The coded communications using non-coherent orthogonal modulation and capacity-approaching binary channel codes namely low-density parity check code (LDPC) and turbo code are investigated in this paper with the focus on the main three characteristic effects of an underwater channel, namely, multi-path propagation, Doppler spread and ambient noise. Additionally, a new method was implemented and tested successfully to identify and eliminate the highamplitude noise from the received dataset.

In this paper, we show that the existence of centrally synergistic potential functions on the n-dimensional sphere, denoted by S~n, is a sufficient condition for the global asymptotic stabilization of a point in S~n. Additionally, if these functions decrease exponentially fast during flows and are bounded from above and from below by some polynomial function of the tracking error, then the reference point can be globally exponentially stabilized. We construct two kinds of centrally synergistic functions: the first kind consists of a finite family of potential functions on S~n while the second kind consists of an uncountable number of potential functions on S~n. While the former generates a simpler jump logic, the latter is optimal in the sense that it generates flows with minimal length.

Image segmentation has became an important research area for various medical imaging fields. The automated complex analytical process makes it a huge time consuming procedure. The intention to microscopic images segmentation is to extract the cellular, nuclear or tissue components. This is considered a challenging process due to the large variations of features of these components (size, shape, orientation or texture). In this paper, a novel approach to deal with rats' microscopic hippocampus images segmentation based on the hybrid evolutionary strategy (ES) is proposed. The proposed work used the quantum-inspired evolutionary algorithm (QIEA) to establish the optimal level for the multilevel thresholding. The QIEA depends on both quantum and evolutionary computing. An intensive works for automatic hippocampus segmentation is performed on a database of 179 images. The acquired results have demonstrated that the proposed algorithm provides superior segmentation with eight levels (L = 8), that offer the highest correlation between the original and the corresponding segmented image. © Copyright 2015 American Scientific Publishers All rights reserved.

The MORPH project (FP 7, 2012-2016) advances a novel concept of an underwater robotic system composed of a number of spatially separated mobile robot-modules, carrying complementary resources. Instead of being physically coupled, the modules are connected via communication links that allow a limited flow of information among them. Without rigid links, the so called Morph Supra-Vehicle can reconfigure itself and adapt in response to the shape of the terrain, including walls with negative slope. The MORPH concept requires new concepts in a number of technological fields. Examples are adaptive sensor placement for perception and navigation or environmental modeling in complex environments. As the project enters its final year the basic developments have been achieved. It is still a huge effort to create a system out of components which can be perceived as a supra-vehicle. This paper focuses on a presentation of the current state.

This paper addresses the problem of keeping an autonomous marine vehicle in a moving triangular formation by regulating its position with respect to two leader vehicles. The follower vehicle has no prior knowledge of the path described by the leaders but has access to their heading angle and is able to measure inter-vehicle ranges. It is assumed that the distance between the leaders is constant and known. A control strategy is adopted that generates speed and heading commands so as to drive suitably defined along track and cross track errors to zero. The commands are used as input to local inner loops for yaw and speed control. The paper describes the algorithms derived for range-based control and assesses their performance in simulations using realistic models of the vehicles involved. Tests with three autonomous marine vehicles equipped with acoustic modems and ranging devices allow for the evaluation of the performance of the algorithms in a real-world situation. © IFAC.

Hybrid control strategy for the autonomous transition flight of a fixed-wing aircraft

IEEE Transactions on Control systems Technology 2013年第6期21卷 2194-2211页

This paper develops a hybrid control strategy that provides autonomous transition between hovered and leveled flights to a model-scale fixed-wing aircraft. The aircraft's closed-loop dynamics are described by means of a hybrid automaton with the hover, transition, level, and recovery operating modes, each one corresponding to a different region of the flight envelope. Linear parameter varying control techniques are employed in hover and level, providing robust local stabilization, and a nonlinear locally input-to-state stable controller provides practical reference tracking to the transition operating mode. These controllers, together with an appropriate choice of reference maneuvers, ensure that a transition from hovered flight to level flight, or vice versa, is achieved. Whenever the aircraft state reaches unexpected values, the recovery controller is triggered in order to drive the aircraft toward stable hovered flight, providing a chance to retry the transition maneuver. The controllers' performance and robustness is assessed within a realistic simulation environment in the presence of sensor noise. © 2013 IEEE.
