  • About the Edition

    Two separate sensing arrays track the same underwater vehicle. The two versions of track are different, but roughly parallel. One possible explanation is the presence of a timing synchronization error. The report provides a model for describing and correcting such errors, estimation algorithms for quantifying the model parameters, and statistical methodology for testing the validity of the effects. The techniques are applied to real data, and the results are reported. Also some properties of the noise process are recorded. Keywords: Sonar sound, Analyzers; Underwater tracking; Calibration; Systematic errors; Components of variance; Synchronization modeling. (JHD).

The static ports have been located to minimize errors. Compensation for the remaining errors is provided by a correction algorithm comprised of three factors: basic correction, thrust effect compensation and ground effects Size: 12MB.

    The book initially develops novel methodologies for the problem of integrated fault diagnosis and control of LTI systems to address current design challenges. The results obtained are then extended to a number of complex linear systems, specifically to Markovian jump systems as well as to . We present a new method for solving stochastic differential equations based on Galerkin projections and extensions of Wiener's polynomial chaos. Specifically, we represent the stochastic processes Cited by:

A Joint Time Synchronization and Localization Design For Mobile Underwater Sensor Networks Article in IEEE Transactions on Mobile Computing 15(3) January with Reads.

A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Aiming at the application demand in underwater noise monitoring, observation of marine animal, antisubmarine and underwater target localization, a high-SNR underwater acoustic signal acquisition (UASA) node that combines a self-contained acquisition system and floating platform is designed to improve the acquisition performance of a single UASA node, and a high-accuracy synchronization Author: Jiajia Jiang, Han Liu, Fajie Duan, Xianquan Wang, Xiao Fu, Chunyue Li, Zhongbo Sun, Xinyuan Dong.

Time synchronization is an important middleware function that supports the Quality of Service (QoS) of systems in wireless sensor array networks. Instead of providing high synchronization accuracy for all application scenarios, we argue that synchronization protocols should be application specific.

In this paper, we exploit the synchronization requirements of target-tracking systems in Author: Jie Shen, Ming Yin, Ji-An Luo, Zhi-Bo Wang, Zhi Wang, Zhen-Hui Li.

This book presents the diverse areas of underwater acoustic signal processing and communication systems through a collection of contributions from prominent researchers in these areas.

Their results, both new and those published over the past few years, have been assembled to provide what we hope is a comprehensive overview of the recent. An underwater acoustic communications system utilizes phase coherent modulation (56) and demodulation (68) in which high data rates are achieved through the use of rapid Doppler removal, a specialized sample timing control technique and decision feedback equalization including feedforward (76) and feedback equalizers (88).

The combined use of these techniques dramatically increases data Cited by: The microwave and RF technology to alter behavior has been well-documented. I have previously documented the frequencies as follows: Tracking and geolocation: approx.

We focus, in this thesis, on the underwater wireless optical communication (UWOC) that employs optical wave as the transmission carriers. In comparison to RF and acoustic counterparts, UWOC has a much. Underwater vehicles that are equipped with UOWC devices can achieve high-speed data transmission and increase the total throughput of UWSNs.

The major concern of optical wireless underwater vehicles is the system energy efficiency. Due to the difficulty in. Lyu, Q., K.

The proposed framework’s performance and stability are subsequently investigated by employing different meta-heuristic algorithms. The value of this new timing synchronization approach was demonstrated this year when, under the supervision of lab manager, Andy McLeod, it was used to synchronize position, velocity and strain sensor data during tow-tank experiments that took place over a five week period.
