Pseudo-range multilateration, often simply multilateration (MLAT) when in context, is a technique for determining the position of an unknown point, such as a vehicle, based on measurement of biased times of flight (TOFs) of energy waves traveling between the vehicle and multiple stations at known locations.
A geofence is a virtual "perimeter" or "fence" around a given geographic feature. [1] A geofence can be dynamically generated (as in a radius around a point location ...
A wave flume (or wave channel) is a special sort of wave tank: the width of the flume is much less than its length. The generated waves are therefore – more or less – two-dimensional in a vertical plane (2DV), meaning that the orbital flow velocity component in the direction perpendicular to the flume side wall is much smaller than the ...
Typically, annual boat maintenance costs about 10 percent of the cost of the boat itself. For example, a boat that cost $20,000 to purchase would cost roughly $2,000 a year to maintain. Examples ...
Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis". [1] "Cost Engineers budget, plan and monitor investment projects. They seek the optimum balance between cost, quality and time requirements." [2]
In 1990 the company developed C.A.T. fins, and by 1992 they had developed a computerized management system to monitor and control boats' features and performance. [6] In 1995 Centurion began manufacturing 'The Wave', a boat specifically designed to create large wakes for Wakeboarding and Wakesurfing.
This stage is called the transition stage and at this stage the rate of wave-making resistance is the highest. Once the hull gets over the hump of the bow wave, the rate of increase of the wave drag will start to reduce significantly. [1] The planing hull will rise up clearing its stern off the water and its trim will be high.

A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast.
