A ship classification society or ship classification organisation is a non-governmental organization that establishes and maintains technical standards for the construction and operation of ships and offshore structures. Classification societies certify that the construction of a vessel complies with relevant standards and carry out regular ...
Flightradar24 ADS-B receiver based on jetvision Radarcape [24]. Flightradar24 aggregates data from six sources: [25] Automatic dependent surveillance – broadcast (ADS-B). The principal source is a large number of ground-based ADS-B receivers, which collect data from any aircraft in their local area that are equipped with an ADS-B transponder and feed this data to the internet in real time.
The angle of list is the degree to which a vessel heels (leans or tilts) to either port or starboard at equilibrium—with no external forces acting upon it. [1] If a listing ship goes beyond the point where a righting moment will keep it afloat, it will capsize and potentially sink.
Vessels are also not allowed to anchor unless there are legitimate circumstances for doing so. [14] Rule 10 – Traffic Separation Schemes. [15] Typically abbreviated to TSS by mariners, these schemes aim to promote the safety of navigation by ensuring ships follow a general direction of travel within defined traffic lanes. [15]
Flight tracking enables travellers as well as those picking up travellers after a flight to know whether a flight has landed or is on schedule, for example to determine whether it is time to go to the airport.
If a ship wants to cross a traffic-lane it should do so at a right angle to avoid endangering ship traffic using the traffic-lanes (although traffic in the lane does not automatically have the right-of-way [1]). To minimize the amount of time a crossing ship spend crossing the traffic-lanes, there should be a right angle between the lane ...
Signals can be in the form of blasts on alarm bells, sounds on the ship's whistle or code names paged over the PA system. Alpha, alpha, alpha is the code for a medical emergency aboard Royal Caribbean and Norwegian ships. [1] Alpha Team, Alpha Team, Alpha Team is the code for a fire emergency aboard Carnival Cruise Line ships.
In software engineering, a class diagram [1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.
