Using the signal of secondary electrons image resolution less than 0. 5 nm is possible.

Using an on-demand model allows features such as having very quick previews while editing, and once the user has finished making changes GEGL will repeat the same operations in full resolution for the final image in the background.

Using mirrors, as in the 18th century overhead version ( illustrated in the History section below ), it is possible to project a right-side-up image.

Using one of these, an image transfer takes 114 ( M1 ) or 110 ( S1 ) seconds.

Using control points ( automatically or manually entered ), the computer performs transformations on one image to make major features align with a second image.

Using cyan and magenta phosphors, a reasonable limited-color image could be obtained.

* Using on-camera flash will give a very harsh light, which results in a loss of shadows in the image, because the only lightsource is in practically the same place as the camera.

Using this design, Crewe demonstrated the ability to image atoms using annular dark-field imaging.

Using varying numbers of Polaroid snaps or photolab-prints of a single subject Hockney arranged a patchwork to make a composite image.

Using ICER, when the primary concern is the bandwidth available to transmit the compressed image, one can set the quality goal to lossless and the given byte quota will determine the amount of compression obtained.

Using original methods plus high-resolution aerial image digital processing software, the team obtained reliable data about city transport traffic volume, speed and ecological parameters of transport flow.

Using a new icon is simply a matter of moving the image into the correct file folder and using the system tools to select the icon.

* Using positive curvature ( magnifying ) lenses, the focus point of the image is changed from its short distance ( about 30 to 40 cm ) to a virtual distance at infinity.

Using the partial images from a holographic recording of the distribution of the complex optical field, the large aperture image can be reconstructed numerically.

Using digital image capture via scanning or digital cameras, bitmap / raster images can be prepared in Photoshop and other photo editing software programs.

Using an image of a thumb ( up, down, or neutral ), participants received feedback on how much money they gained or lost.

Using simple lenses and low-powered, coherent LED ’ s, the device offers exquisite sensitivity and reproducibility and is able to image with remarkable resolution beyond the classical diffraction limit.

Using a partial differential equation ( PDE )- based method and solving the PDE equation by a numerical scheme, one can segment the image.

Using the Imperial mint in Milan he had coins struck bearing Postumus's image as Emperor with appeals to the faith of his former comrades of the cavalry on the reverse.

Using privately-owned vehicles was a personal hardship for such employees, and the matter of providing state transportation was felt perfectly justifiable.

Using a steering system that controlled the modified rocket's tail surfaces and wings equipped with ailerons, Fiedler was to land the missile on a skid especially bolted under the fuselage.

Using former slaves in the military was official government policy after the issuance of the Emancipation Proclamation.

Using the once popular vortex theory of gravity, the possibility of matter with negative gravity was discussed by William Hicks in the 1880s.

Using this physical explanation of electromagnetic motion, Ampère developed a physical account of electromagnetic phenomena that was both empirically demonstrable and mathematically predictive.

Using his excellent knowledge of Greek, which was then rare in the West, to his advantage, he studied the Hebrew Bible and Greek authors like Philo, Origen, Athanasius, and Basil of Caesarea, with whom he was also exchanging letters.

Using Nevado Mismi, which in 2001 was labeled by the National Geographic Society as the Amazon's source, these scientists made new calculations of the Amazon's length.

Using these inhibitors it was discovered that cells can die while displaying a morphology similar to apoptosis without caspase activation.

Using F for the drag force, ρ for the density, S for the area of the flat plate, V for the flow velocity, and θ for the inclination angle, his law was expressed as

Using conventional construction techniques, they designed a series of " bioshelter " projects, the most famous of which was the Ark Bioshelter community for Prince Edward Island.

Using this device, he confirmed that an invisible current flowed from the glowing filament through the vacuum to the metal plate, but only when the plate was connected to the positive supply.

Using the name " Edgar A. Perry ", he claimed he was even though he was 18.

Using these modelling techniques, Malthus ' population principle of growth was later transformed into a model known as the logistic equation:

Using tonewheels to generate musical sounds as electrical signals by additive synthesis, it was capable of producing any combination of notes and overtones, at any dynamic level.

Using synchronized clockwork-powered switches at the transmitting and receiving ends, he was able to transmit five messages simultaneously ; the system was officially adopted by the French Post & Telegraph Administration five years later.

Using the principle of equivalence, Einstein concluded that the same thing holds in any gravitational field, that the rate of clocks R at different heights was altered according to the gravitational field g. When g is slowly varying, it gives the fractional rate of change of the ticking rate.

Using whatever equipment the vassal could obtain by virtue of the revenues from the fief, the vassal was responsible to answer calls to military service on behalf of the lord.

Using the matchlock mechanism, the powder in the gun barrel was ignited by a piece of burning cord called a " match ".
