Advanced control algorithms using LQG and adaptive control techniques enable the design of an economically attractive alternative for conventional fin stabilizers and have proved to be robust during simulation experiments and full-scale trials. Abstract-This paper describes the design of an autopilot for rudder roll stabilization for ships. This autopilot uses the rudder not only for course kee...
We investigated effects of roll (rotation around line of sight) and pitch (rotation around the horizontal axis) components of retinal flow on heading judgement from visual motion information. It was found that performance level of human observers for yaw (rotation around the vertical axis) plus pitch is little different from that for only yaw although there is bias in perceived heading toward t...
Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying (OQPSK) are two wellaccepted modulation techniques used in Code Division Multiple Access (CDMA) system. The Pulse-Shaping Filters play an important role in digital transmission. The type of Pulse-Shaping Filter used, and its behavior would influence the performance of the communication system. This in turn, would have...
In order to study the dynamic behavior of ships navigating in severe environmental conditions it is imperative to develop their governing equations of motion taking into account the inherent nonlinearity of large-amplitude ship motion. The purpose of this paper is to present the coupled nonlinear equations of motion in heave, roll, and pitch based on physical grounds. The ingredients of the for...
The edge waviness in hot rolled steel is a common defect. Variables that affect such defect include raw material and machine. These variables are necessary to consider to understand such defect. This research studied the defect of edge waviness for SS 400 of metal sheet manufacture. Defect of metal sheets were divided into two groups. The specimens were investigated on chemical composition and ...
The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The short beam theory based on ela...
