The steering gear system has three main parts:

control equipment
power unit
transmission to the rudder stock.
In brief, the operation of the steering gear can be explained as - With the help of the control system, a signal of desired rudder angle is sent from the bridge. This signal activates the power unit with which the rudder is attached. The rudder moves with the help of the power unit till the right angle is reached. ....etc

Television systems that have a resolution that meets standards but not considered high definition, this is what Standard-definition television or SDTV refers to. This usually refers to digital television, especially while broadcasting at the same (or similar) resolution as analog systems. In ATSC, SDTV can be broadcast in 704 pixels × 480 lines with 16:9 aspect ratio (40:33 rectangular pixel), 704 pixels × 480 lines with 4:3 aspect ratio (10:11 rectangular pixel) or 640 pixels × 480 lines with 4:3 ratio (and squ ....etc

This paper discusses new techniques which aim to overcome the shortcomings of the protective system. These techniques are composed of advanced monitoring and control, automated failure location, automated intelligent system reconfiguration and restoration, and self-optimizing under partial failure.


The first electrical power system was installed on the USS Trenton in 1883 (Ykema 1988). The system consisted of a single dynamo supplying current to 247 lamps at a voltage of 10 volts d.c. Until the 1914 to 1917 period, the early electrical pow ....etc

ABSTRACT

The Magneto Hydro Dynamic (MHD) propulsion thruster is designed to use magneto hydrodynamic force generated by sending electric current through a magnetic field created in sea water by superconducting magnets. The principle of MHD propulsion is to apply the Fleming's left hand rule of electromagnetics to sea water directly .In this propulsion system magnetic field is created in sea water by magnets fixed on a hul1. When electric current is sent to sea water at right angles to the magnetic field, and electromagnetic force (Lorentz f ....etc

ABSTRACT

In the last years one of the main technological efforts in satellite communications is the integration of digital broadcast services with two-way communications: this is justified by the research of new business perspective and in the increase of technological efficiency.
Traditionally, common air interface (CAI) standards have been rigorously defined in great detail to ensure optimized operation for specific application and to permits the interoperability between the equipment of different manufactures devices. In this context, S ....etc

REDUCED EMISSIONS OF OXIDES OF NITROGEN IN SHIP ENGINES

INTRODUCTION

Oxides of nitrogen emission from ship engines are significant on a global level. These emissions participate in the formation of photochemical smog and acid rain. Here we look at to some ways by which these emissions can be reduced.

Mechanism of NOx Formation in Diesel Engines.

At the temperature of the Burning of fuel spray (about 2000 K to 2500 K).

Definition

Compact peripheral component interconnect (CPCI) is an adaptation of the peripheral component interconnect (PCI) specification for industrial computer applications requiring a smaller, more robust mechanical form factor than the one defined for the desktop. CompactPCI is an open standard supported by the PCI Industrial Computer Manufacturer's Group (PICMG). CompactPCI is best suited for small, high-speed industrial computing applications where transfers occur between a number of high-speed cards.

It is a high-performance indust ....etc
