A bar with cut teeth for engaging into a pinion. A linear motion of the bar is then converted into a rotary motion of the pinion.
A variant of the rack and pinion system in which only one panel is propelled by the rack system, the other being opened by a wire led from the driven panel.
1. A distortion of the hull structure caused by a strain from a disturbed sea. 2. The deformation of the container end or side frame as a result of static and dynamic forces parallel to the deck.
An electronic navigation aid using radio waves sent out as a narrow beam to detect solid objects around the ship.
The whole process of target detection, tracking, calculation of parameters and display of information.
A radial turbine is a turbine in which the flow of the working fluid is radial to the shaft.
A category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to cool.
In physics radiant energy is the energy of electromagnetic and gravitational radiation, its SI unit is the joule (J). Most commonly used in the fields of radiometry, solar energy, heating and lighting
In radiometry, radiant exposure or fluence is the radiant energy received by a surface per unit area.
In radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted or received, per unit time.
A category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat.
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation.
Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this".
n the United States, the person within an organization responsible for the safe use of radiation and radioactive materials as well as regulatory compliance.
Radiative cooling is the process by which a body loses heat by thermal radiation.
Radiative forcing is the difference between solar irradiance (sunlight) absorbed by the Earth and energy radiated back to space.
Radiators are heat exchangers. They are used for either cooling or heating purposes.
A means of sending signals through space using electromagnetic waves generated by high frequency, alternating currents, i.e. 15 kHz to 100 MHz.
A radio direction-finding system on board the ship provides the means of establishing the ship position based on the location of fixed transmitting stations.
He maintains and monitors radio, sends and receives messages. Often maintains electronic navigation equipment.
