Rarefaction waves expand with time (much like sea waves spread out as they reach a beach); in most cases rarefaction waves keep the same overall profile ('shape') at all times throughout the wave's movement: it is a self-similar expansion. Each part of the wave travels at the local speed of sound, in the local medium.
Having leaflet s that radiate from a central point (usually at the top of a petiole), like spread-out fingers radiating from the palm of a hand. Compare palmate. compressed Flattened lengthwise, either laterally (from side to side) or dorsally (from front to back). concatenate
A typical suburban development in the United States, located in Chandler, Arizona An urban development in Palma, Mallorca. Urban sprawl (also known as suburban sprawl or urban encroachment) [1] is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city".
The word diffusion derives from the Latin word, diffundere, which means "to spread out". A distinguishing feature of diffusion is that it depends on particle random walk, and results in mixing or mass transport without requiring directed bulk motion. Bulk motion, or bulk flow, is the characteristic of advection. [1]
They spread out above or along the soil surface. Roots and new plants develop at the nodes or ends. Stoloniferous – a plant that produces stolons. Stoma – a small pore on the surface of the leaves used for gas exchange with the environment while preventing water loss. Suberose – having a corky texture.
The spread of ideas is sometimes considered a third broad category, though that is often considered part of memetics. Paul Marsden has said behavioural contagion can be split into six subcategories: hysterical contagions , deliberate self-harm contagions, contagions of aggression, rule violation contagions, consumer behaviour contagions, and ...
Spreading activation is a method for searching associative networks, biological and artificial neural networks, or semantic networks. [1] The search process is initiated by labeling a set of source nodes (e.g. concepts in a semantic network) with weights or "activation" and then iteratively propagating or "spreading" that activation out to other nodes linked to the source nodes.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
