, in oceanography.



independent fluctuations of the surface of the ocean or sea during a complete calm, consisting of long and sloping waves up to 10–15 m high and 300–400 m long and with phases of up to 17–20 sec. They result from the conversion of wind waves during their departure from an area of wind activity or after the dying down of winds. Waves of a swell are nearly indistinguishable in terms of size and shape. Particles of water in such waves move in regular circular orbits.


The volumetric increase of soils on being removed from their compacted beds due to an increase in void ratio.
A local enlargement or thickening in a vein or ore deposit.
A low dome or quaquaversal anticline of considerable areal extent; long and generally symmetrical waves contribute to the mixing processes in the surface layer and thus to its sound transmission properties.
Gently rising ground, or a rounded hill above the surrounding ground or ocean floor.
(mining engineering)
Ocean waves which have traveled away from their generating area; these waves are of relatively long length and period, and regular in character.


a. the undulating movement of the surface of the open sea
b. a succession of waves or a single large wave
2. a gentle hill
3. Music a crescendo followed by an immediate diminuendo
4. Music
a. a set of pipes on an organ housed in a box (swell box) fitted with a shutter operated by a pedal, which can be opened or closed to control the volume
b. the manual on an organ controlling this

Research by Blayney, Kalyuga, & Sweller (2010) indicated that older students in an first year accounting course tend to have less experience in using new information technologies as do those students who have recently left school.
According to Sweller (1990), a worked example is to focus on the problem and state and carry on a relevant a kind of course that carry out (such as the order of solving the problem) to give a demonstration, help students to assimilate the base mould or improve the problem of combining and solve ability, too.
Paas, Renki, and Sweller (2003) further categorized cognitive load into three types: intrinsic cognitive load, extraneous (ineffective) cognitive load, and germane (effective) cognitive load.
Although they stamp their trademarks over numbers such as mid-tempo sweller I Just Got Over You, acoustic 60s folk pop You'll Never and lysergic folksy swayer Man In The Middle, Sealey's first writing contribution, it's the departures from the norm that really set this apart.
Based on the theoretical foundations derived from the work of Sweller (1994), cognitive load theory (CLT) assumes a limited working memory which is connected to a virtually unlimited long-term memory.
