  2. Precession electron diffraction - Wikipedia

    en.wikipedia.org/wiki/Precession_electron...

    PED possesses many advantageous attributes that make it well suited to investigating crystal structures via direct methods approaches: [1] Quasi-kinematical diffraction patterns: While the underlying physics of the electron diffraction is still dynamical in nature, the conditions used to collect PED patterns minimize many of these effects.

  3. Site analysis - Wikipedia

    en.wikipedia.org/wiki/Site_analysis

    There are numerous site elements related to the analysis during this phase. This is part of the analysis phase in site planning. Synthesis phase: From the analysis, a program is developed, which is part of the synthesis phase. The third step deals with schematic design of a site plan as well as a preliminary cost estimate for the site. Step ...

  4. Data - Wikipedia

    en.wikipedia.org/wiki/Data

    Data are analyzed using techniques such as calculation, reasoning, discussion, presentation, visualization, or other forms of post-analysis. Prior to analysis, raw data (or unprocessed data) is typically cleaned: Outliers are removed, and obvious instrument or data entry errors are corrected.

  6. Edge effects - Wikipedia

    en.wikipedia.org/wiki/Edge_effects

    Edge effects in biological assays refer to artifacts in data that are caused by the position of the wells on a screening plate rather than a biological effect. [ citation needed ] The edge effect in scanning electron microscopy is the phenomenon in which the number of secondary and/or backscattered electrons that escape the sample and reach the ...

  7. Scale-invariant feature transform - Wikipedia

    en.wikipedia.org/wiki/Scale-invariant_feature...

    From the full set of matches, subsets of keypoints that agree on the object and its location, scale, and orientation in the new image are identified to filter out good matches. The determination of consistent clusters is performed rapidly by using an efficient hash table implementation of the generalised Hough transform .

  8. Suitability analysis - Wikipedia

    en.wikipedia.org/wiki/Suitability_analysis

    Suitability analysis in a GIS context is a geographic, or GIS-based process used to determine the appropriateness of a given area for a particular use. The basic premise of GIS suitability analysis is that each aspect of the landscape has intrinsic characteristics that are to some degree either suitable or unsuitable for the activities being ...

  9. Data remanence - Wikipedia

    en.wikipedia.org/wiki/Data_remanence

    Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...
