The performance of dasymetric techniques using these types of ancillary data is compared to that of areal weighting and traditional land cover-based dasymetric techniques.
Technical details about Seagate's landmark areal density achievement can be found at: http://www.
To avoid problems associated with information collected at the micro-level, spatial analysts and agencies that collect spatial entity information often aggregate data in predefined zonal or areal units (Mennis 2003).
Factors that could cause actual results to differ include, but are not limited to: the company may not succeed in extending the areal density beyond 36 gigabits per square inch; the company may be unsuccessful in obtaining design wins and qualifications with its customers on future programs; and the other factors described in the company's reports filed with the Securities and Exchange Commission, including, but not limited to, its Annual Report on Form 10-K for fiscal 1998 and quarterly reports on Form 10-Q for the first, second and third quarters of Fiscal Year 1999.
For instance, population density for a given enumeration unit can be normalized by dividing the total population by the areal measurement of the unit.
In 1991, IBM's work on AMR technology led to the development of MR (magnetoresistive) heads capable of the areal densities required to sustain the disk drive industry's continued growth in capacity and performance," says Paul Scheuer, IBM's strategy manager, Tape Storage.
Different parameterizations of IDM are compared with other, conventional areal interpolation methods.
Magnetic recording for both tapes and disk encountered few real limits in the 1990s as witnessed by a 60-plus percent compounded annual areal density growth rate.
Veeco's NEXUS PVD multi-target system is used to deposit high-quality, extremely uniform, thin film multi-layer stacks and will be used by the customer to manufacture high areal density Tunneling Magneto-Resistive (TMR) heads.
Areal interpolation is the process of estimating the values of one or more variables in a set of target polygons based on known values that exist in a set of source polygons.
