STATISTICAL MODEL
Jakes fading model
Rayleigh fading is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.
Collaborative mapping         
AGGREGATION OF WEB MAPS AND USER-GENERATED CONTENT, FROM A GROUP OF INDIVIDUALS OR ENTITIES, AND CAN TAKE SEVERAL DISTINCT FORMS
Collaborative Mapping; Citizen mapping
Collaborative mapping is the aggregation of Web mapping and user-generated content, from a group of individuals or entities, and can take several distinct forms. With the growth of technology for storing and sharing maps, collaborative maps have become competitors to commercial services, in the case of OpenStreetMap, or components of them, as in Google Map Maker and Yandex.

IMAGING TECHNIQUES USED TO COLOCALIZE SITES OF BRAIN FUNCTIONS OR PHYSIOLOGICAL ACTIVITY WITH BRAIN STRUCTURES
Brain Mapping; Brain map
Brain mapping is a set of neuroscience techniques predicated on the mapping of (biological) quantities or properties onto spatial representations of the (human or non-human) brain resulting in maps.

Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between type systems using object-oriented programming languages. This creates, in effect, a "virtual object database" that can be used from within the programming language.

TYPE OF FADING FOR RADIO AND OTHER ELECTROMAGNETIC WAVES
User:Gregdurgin/sandbox; Draft:Two-Wave with Diffuse Power (TWDP) Fading; Two-Wave with Diffuse Power (TWDP) Fading; TWDP fading
In radio propagation, two-wave with diffuse power (TWDP) fading is a model that explains why a signal strengthens or weakens at certain locations or times. TWDP models fading due to the interference of two strong radio signals and numerous smaller, diffuse signals.

Fading

In wireless communications, fading is variation of the attenuation of a signal with various variables. These variables include time, geographical position, and radio frequency. Fading is often modeled as a random process. A fading channel is a communication channel that experiences fading. In wireless systems, fading may either be due to multipath propagation, referred to as multipath-induced fading, weather (particularly rain), or shadowing from obstacles affecting the wave propagation, sometimes referred to as shadow fading.
