Combining the information given by the focal map (z-height) and the mass circle (number of atom), a three-dimensional model of two molecule chains can be reconstructed (Fig. 5) that faithfully reproduces the input structure.
For the final data collection, playback treatments were amplified with a Vision David Speaker connected to a MP3-Player (Samsung YP-U3) from about 75 m distance of the focal group at a height of 2 m [ 35, 46].
Its silhouette is subtly tapered, he says, so its facades converge at an imaginary focal point 10 times its height – a learned nod to Edwin Lutyens Cenotaphh memorial in Whitehall, whose planes meet at a projected spot 1,000ft in the air.
"To really get a sense of the park, we'd need to insert tiny lipstick cameras throughout the model, with the proper lens focal lengths to represent the height of people.
The optics of the device is so designed as to measure a maximum intensity when the distance between the focusing lens and the selected point on the free surface is equal to the focal length, thus enabling a height measurement.
In this study, we examined the spatial property of focal adhesions by changing the height of micropatterns in two kinds of microtopography (grid and post) and the stiffness of the substrates.
At 8.4 MHz the calculated laser intensity at the focus would ionize nitrogen at a rate of 107 s−1[36] but falls as a function of height above the focal plane due to the increased laser spot diameter.
An independent consultancy company provides an online lens calculator based on the standards of the Home Office, LensCalc (CCTV Advisory Service, 2008), to help determine the subject distance required to achieve specified subject heights for different combinations of sensor size, subject height, and lens focal length (see Table 1).
Using a camera geometry setup in [24], the image coordinates (i x, i y ) is projected to the world coordinates (w x, w y ) by the following equations w_{x} = - frac{{h i_{x} }}{{f sin varphi + i_{y} cos varphi }}, (1) w_{y} = frac{{h i_{y} }}{{sin varphi left( {f sin varphi + i_{y} cos varphi } right)}}, (2 where h is the camera height, f the focal length and φ the tilt angle.
