Nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. These types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. In the current study, the performance of floating breakwater (FBs) under regular waves was studied using the physical modeling method. For the mode...

Restoration of realistic animation is a critical part in the area of computer graphics. The goal of this sort of simulation is to imitate the behavior of the transformation in real life to the greatest extent. Physics-based simulation provides a solid background and proficient theories that can be applied in the simulation. In this dissertation, I will present real-time simulations which are ph...

Fault detection and isolation are very important elements in the design of faulttolerant decision support systems for ship operator guidance. This study outlines remedies that can be applied for fault diagnosis, when the ship responses are assumed to be linear in the wave excitation. A novel numerical procedure is described for the calculation of residuals using the ship’s transfer functions wh...

This paper deals with various aspects of ship evacuation: Guidelines, Simulation, Validation, and Acceptance Criteria. The paper is structured along those aspects. The first chapter deals with general aspects of ship evacuation, like environmental influences, ship motion, the special procedures on board ships, etc. The second chapter covers the guidelines applicable to evacuation analyses for p...

In this paper the coupling between the sea, the ship and humans is studied. In previous researches mathematical models of fast ship’s motions have been determined. In the literature there are models of human sickness and models of the sea. This knowledge about seasickness, waves and ship motion has been gathered. Using this information it is possible to extract some criteria for the captain (ma...

The need for maritime freight transport of various goods has never been greater. Consequently, ships are designed with ever-increasing dimensions, the emphasis, course, on length. One many challenges in design large is prediction their behavior waves, i.e., motions, and consequently, added resistance. In this paper, a comparative study two numerical tools estimating ship motions resistance pres...

For validating theoretical models aiming to simulate the postural behaviour of working personnel one of the possible methods is the execution of trials onboard full-scale ships. This kind of tests requires measuring ship and human movement simultaneously. Up to now, international guidelines for standardizing human postural stability tests onboard have not been established. Scientific works focu...

This paper presents a survey of neural network controllers for AUVs. A direct adaptive neural net controller incorporating integral action was designed for the heave motion of the ODIN underwater vehicle. The neural net controller is trained on-line by parallel recursive error prediction method and the critic equation. The influence of the various design parameters of the neural net controller ...

In this paper, theoretical and experimental implementation of heave compensation on a redundant hydraulically actuated manipulator with 3-dof has been carried out. The redundancy is solved using the pseudo-inverse Jacobian method. Techniques for minimizing velocities and avoiding mechanical joint saturations is implemented in the null space joint motion. Model based feed-forward, combined with ...
