### motion | wave:

Wavelet
* allow signals to be decomposed into various parts, some of which can simply be thrown away.
* also are localized functions, which is important at the edges of images
  - have important applications in information transfer data processing
* are a mathematical tool for hierarchically decomposing functions
  - new approach used in the analysis of sounds and images
  - useful tool for analyzing self-similar behavior
* are also good at representing images parsimoniously, with very few bits of information
  - useful in data compression and other forms of signal processing
  - especially useful in analyzing transients or time-varying signals
  - functions generated from one basic function by dilations and translations
  - functions, like sines and cosines, that satisfy certain requirements
  - similar to sines and cosines in that they look like waves of various frequencies
  - sophisticated algorithms that interpret features of an image or other data
* belong to the class of nonuniform filter banks.
* constitute an important tool for signal and image processing.
* form a versatile tool for representing general functions or data sets.
* have applications to practical image compression methods, and texture characterization
  - remarkable properties
* provide complete, sometimes non-orthogonal, sets of basis functions
  - systematic tools for signal processing of nonlinear and time-varying systems
* use artificial building blocks that have the advantage of localization in space
  - complex base functions, with some coarse features akin to sine waves

Whitecap
* are always white
* disguise the splashes whales make when they break the surface.
* run to the horizon, blown by a stiff wind.

Wind wave
* are a more localized phenomenon
  - very efficient agents of size-sorting
* tend to be smaller, while swell waves tend to be larger.

### motivation:

Compulsion
* are behaviors that are repeated over and over again in a very set way
  - which help reduce the anxiety surrounding the obsessions
  - conscious, repetitive behavioral or mental acts which serve to allay anxiety
  - impulses to perform a variety of stereotyped behaviors or rituals
  - obsessive rituals or actions the person feels urgently compelled to engage in
  - repeated behaviors, patterns and rituals that reduce anxiety caused by obsessions
  - repetitious rituals used to relieve that anxiety
  - repetitive actions, usually performed in response to obsessions
* are repetitive behaviors or mental acts done to prevent or reduce anxiety
  - performed to relieve or prevent anxiety
  - that are performed in an effort to reduce anxiety
  - behaviors, such as counting, hoarding, washing, and arranging
  - intentional behaviors that are carried out in a stereo-typed fashion
  - rituals such as handwashing, counting, checking, hoarding, or arranging
* are the acting out of the obsessive thoughts
  - conscious behaviors that one chooses to do in order to feel comfortable
* coping strategy.
* fall under the rubric of anxiety disorders.
* is causing.
* repetitive behavior in response to urges.
* serious matter when it applies to an individual.

### motivation:

Extrinsic motivation
* are rewards that come from outside our self.
* arises from external rewards and can be influenced through monetary rewards.
* can effect a child for life.
* involves engaging in activity for some external consequence.
* is associated with learning made to occur by forces outside the person
  - based on concrete or overt rewards
  - only one idea in a wide range of actions that produce student motivation
  - responsive to rewards delivered by second parties
  - the kind of motivation awards encourage
* refers to motivation to engage in an activity as a means to an end.
