In near-shore transforming seas, as waves approach the shoreline, wave shoaling and sometimes wave breaking take place due to the decreasing water depth. When a ship advances through the transforming seas, the ship body and waves interact with each other substantially and can lead to unknown motions of the ship hull. The physical process of how the wave transforms in the surf zone and how the vehicle actually behaves when it passes through the transforming seas is a complicated issue that ...

Bibliography: pages 124-135. / With the increase in ship sizes, there has been an increased interest in the prediction of ship motions in shallow water, where the possibility of grounding becomes a problem. Theoretical equations governing the ship's motions have been formulated involving various hydrodynamic coefficients. In this thesis these coefficients have been found experimentally for a range of water depths and wave periods. The methods for solving the equations of motion theoretically are...

Advances in low power electronic devices design open up the possibility of self powering a small wireless device from harvested ambient power. In a ship environment, low level vibration is considered as an appropriate power source to extract energy. After a survey of three mechanisms to convert mechanical motion to electricity, electromagnetic conversion was chosen as a mechanism of energy harvesting in this thesis. One of the major drawbacks of today's energy harvesters is that they are de...

The SH2 containing inositol 5'-phosphatase (SHIP) is a hemopoieticspecific protein that catalyzes the hydrolysis of the phosphatidylinositol 3-kinase (PI3K)-generated second messenger PI-3,4,5-P₃ (PIP₃), to PI-3,4-P₂ (PIP₂) and thereby negatively regulates hemopoietic cell survival, proliferation, differentiation and activation. Herein, macrophage development and function were compared in SHIP+/+ and -/- mice. SHIP was found to restrain in vitro bone marrowderived macrophage (BMMφ) surviva...

The Arsenal Ship provides a remote magazine for other joint warfare systems to utilize, with limited ability to defend itself. Ultimately, it resembles a combat logistics ship designed to sail into harm's way ready to provide the initial punch as required. Therefore, it should be minimally manned by employing the most cost effective technology. With the requirement to reduce crew size, a ne...

Approved for public release; distribution is unlimited. / As an example of ships used as weapons (SAW), an oil tanker is hijacked and commandeered by terrorists to collide with a high-value maritime or shore target. If sunk or destroyed in a shipping lane as a result of a counter measure, the SAW’s collateral damage would severely disrupt the traffic flow in the shipping lane. To prevent such a disruptive catastrophe, non-destructive measures must be implemented to cause the SAW to deviate from ...

The problem of ship steering in canals and confined waters is analyzed with emphasis on stability and bifurcation analysis. The classical maneuvering equations of motion augmented with a model for ship/canal interaction are used to model the open loop dynamics. Coupling of a control law and a guidance scheme with appropriate time lags is employed to model the essential dynamics of a helmsman. The complete system is analyzed using both linear and nonlinear techniques in order to assess its stabil...

The primary objective of this project is to estimate the effectiveness of decoys against incoming missile attacks in a multiple-ship battle group (BG) environment. In this problem, we allow the number of ships, number of decoys, and the values of ships to vary. We also vary the values of the hard kill probabilities, the splash probabilities of decoyed missiles, probabilities that a missile's lock is broken by seduction decoys and the quality factor of the distraction decoys. When an Antiship Cru...

Thesis (MScEng)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: When a sailing ship passes a moored ship the moored ship experiences forces and moments. These forces and moments cause the moored ship to move. The resulting ship motions due to the passing ship can sometimes be more severe than the ship motions due to ocean waves and can cause serious accidents at moorings such as the failing of mooring lines or even the total break away of the ship from the berth. Since bulk carriers and ...

The SH2-containing inositol-5'-phosphatase, SHIP, has been shown, by comparing SHTP+/+ and -/- cells, to be. a critical negative regulator of the phosphatidylinositol (PI)-3- kinase (PI3K) pathway in many hematopoietic cell lineages. However, SHIP-/- mice are neither polycythemic nor profoundly anemic and we wanted to know why. Our studies revealed that SHIP-/- mice suffer from reticulocytosis and show an enhanced recovery from phenylhydrazine (PHz)-induced anemia accompanied by a more rapid acc...

Computational Fluid Dynamics (CFD) has been around for many years. It is a computer tool that can be used to find the hydrodynamic fluid performances. In ship design it is used in a wide area from smoke propagation to resistance estimations. It is however in resistance estimations that CFD have had most focus and research. There are many tools a designer can make use of nowadays. Most of the tools are computer based. This is optimization algorithms, computer aided design (CAD) and computational ...

The demand for increase in length and speed of the ships is increasing due to this the study for flexibility of structures is becoming important.

A ship berthing plan assigns surface vessels a berth prior to their port entrance, or reassigns ships once in port to allow them to accomplish in a timely manner maintenance, training, and certification events which build readiness for future operational commitments. Each ship requires different services when in port, such as shore power, crane services, ordnance, and fuel. Unfortunately, not all services are offered at all piers. At present, ship berthing plans are manually prepared by a port o...

While ocean waves were among the first natural phenomenon to be modeled satisfactorily in computer graphics, waves from ships—ship wakes—have been largely ignored. The model presented in this thesis is suitable for animating wakes created by a ship moving along an arbitrary course. Instead of the dynamic solution of a free-surface problem that can be computationally expensive and unstable, the approach presented is kinematic and while ad hoc, is efficient and simple to implement. The model...

The fleet consists of 6 LNG carriers where 3 have a loading capacity of 44 000 tons while the remaining 3 ships can lift 33 00 tons of LPG. Since the ships are set to operate at speeds between 14 and 20 knots it is necessary to upgrade the prime movers as the service speeds range from 14.5 to 16.7 knots. BW Clipper will prove to be far more effective in terms of fuel consumption compared to the other ships due to higher initial service speed and a relatively efficient engine. The fleet will oper...
