MOS date September 2011 Environmentalscanning is one component of the global environmental analysis. Environmental monitoring , environmental forecasting and environmental assessment complete the global environmental analysis. Environmentalscanning refers to the macro environment.The global environment refers to the macro environment which comprises industries, markets, companies, clients and competitors. Consequently, there exist corresponding analyses on the micro level. Suppliers, customers and competitors representing the micro environment of a company are analyzed within the industry analysis. ref Dillerup, R., Stoi, R. 2006 , Unternehmensf hrung , Vahlen , p. 179 et seq. p. 187 et seq. ref Environmentalscanning can be defined as the study and interpretation of the political, economic, social and technological events and trends which influence a business, an industry or even a total market . ref Kroon, J. 1995 , General Management 2nd Edition , Pearson South Africa , p. 76 ref The factors which need to be considered for environmentalscanning are events, trends, issues and expectations of the different interest groups. Issues are often forerunners of trend breaks. A trend break could be a value shift in society, a technological innovation that might be permanent or a paradigm change.

Duplex scanning is a feature of Image scanner computer scanner s and Multifunction printer multifunction printers MFPs that allows the automatic scanning of a sheet of paper on both sides. Devices without this capability can only scan a single side of a sheet of paper at a time. In general, duplex scanning is achieved on Multifunction printer multifunction printers using a Automatic Document Feeder Reversing Automatic Document Feeder RADF . Duplex scanning is achieved on computer scanners by either RADF or by single pass duplex scanning using two cameras one for the front side of the document and one for the back side of the document.

Parallax scanning depth enhancing imaging methods rely on discrete parallax differences between depth planes in a scene. The differences are caused by a parallax scan. When properly balanced tuned and displayed, the discrete parallax differences are perceived by the brain as depth. A continuously moving parallax scan records a pattern of sequential parallax views on a single strip of film or video tape. The lens s optical axis sweeps in the plane of the nominal X and Y axes around the nominal optical Z axis, pivoting on the optical convergence point out along the Z axis , so that it passes through positions having parallax in relation to the optical convergence point. The circular scanning of the lens s optical axis traces out a coaxial cone pattern with the convergence point as its apex. Early tests revealed that the brain will translate parallax scanned information into depth information at scanning frequencies of between 3 6 Hz, and that the ideal frequency is 4.31 Hz.

orphan date August 2010 Strain scanning refers to several diffraction based techniques using X rays and neutrons where the crystalline lattice of a material is, in effect, used as a form of strain gauge . The various methods are derived from powder diffraction but look for the small shifts in the diffraction spectrum that indicate a change a lattice parameter instead of trying to derive unknown structural information. By comparing the lattice parameter to a known reference value it is possible to determine the Strain materials science strain . If sufficient measurements are made in different directions it is possible to derive the strain tensor and hence the Stress physics stress tensor. Principles At its most basic level strain scanning uses shifts in Bragg s Law Bragg diffraction peaks to determine the strain. Strain is defined as the change in length shift in lattice parameter, d divided by the original length unstrained lattice parameter, d sub 0 sub . In diffraction based strain scanning this becomes the change in peak position divided by the original position. The precise equation is presented in terms of diffraction angle, energy, or for relatively slow moving neutrons time of flight math epsilon frac Delta d d 0 frac Delta theta theta 0 frac Delta E E 0 frac Delta t t 0 , math Methods The details of the technique are heavily influenced by the type of radiation used since lab X rays, synchrotron X rays and neutrons have very different properties. Nevertheless, there is considerable overlap between the various methods.

Conical scanning is a system used in early radar units to improve their accuracy, as well as making it easier to steer the Antenna radio antenna properly to point at a target. Conical scanning is similar in concept to the earlier lobe switching concept used on some of the earliest radars, and many examples of lobe switching sets were modified in the field to conical scanning during World War II , notably the German W rzburg radar . With simple electronics, antenna guidance can be made entirely automatic, although potential failure modes and susceptibility to deception jamming led to the replacement of conical scan systems with monopulse radar sets. They are still used by the Deep Space Network for maintaining communications links to space probe s. ref Citation last Gawronski first Wodek last2 Craparo first2 Emily title Antenna Scanning Techniques for Estimation of Spacecraft Position journal IEEE Antennas and Propagation Magazine volume 44 issue 6 pages 38 45 date December 2002 url http faculty.nps.edu emcrapar gawronski.pdf issn 1045 9243 ref The Spin stabilisation spin stabilized Pioneer 10 and Pioneer 11 probes used onboard conical scanning maneuvers to track Earth in its orbit. ref cite web title Weebau Spaceflight Encyclopedia date 9 November 2010 url http weebau.com satplan pioneer 2010.htm accessdate 11 January 2012 ref Concept A typical radar antenna commonly has a beam ....

Image Sicm.jpg 400px right The scanning ion conductance microscope SICM consists of an electrically charged glass micro or nanopipette probe filled with electrolyte lowered toward the surface of the sample which is non conducting for ions in an oppositely charged bath of electrolyte. As the tip of the micropipette approaches the sample, the ion conductance and therefore current decreases since the gap through which ions can flow, is reduced in size. Variations in the ion current are measured by an amplifier, and are used as a feedback signal by a scanner control unit to keep the distance between pipette tip and sample constant by applying corresponding voltages to the Z piezo drive during the scanning procedure. Therefore, the path of the tip follows the contours of the surface. The SICM can also sample and map the local ion currents above the surface. This is useful in imaging ion currents through membrane channels. This scanning technique can be used on living tissues, whereas traditional SEM imaging necessitated killing the sample. Biological processes can now be observed whilst in action. SICM is part of the larger family of scanning probe microscopy SPM , and was specially designed for the sub micrometer resolution scanning of soft non conductive materials that are bathed in electrolyte solution.

Whole body nuclear scanning is a medical imaging technique where the whole body is scanned, contrary to, e.g., neuroimaging where only the brain is scanned. Whole body nuclear scanning may refer to several different modalities Nuclear magnetic resonance imaging, also known more commonly as magnetic resonance imaging MRI But normally it would probably refer to a nuclear medicine tomographic imaging technique such as Single photon emission computed tomography SPECT Positron emission tomography PET dab ... more details
