The spotlight often falls on the role women played, from recording code to calculating patterns and operating code-breaking machines.
Measured pattern of solid 1, solid 2 and calculated pattern from X-ray structure of polymorph 1, polymorph 2. The crystal structure of polymorph 1 consists of the symmetric 3,4-dimethoxy curcuminoid molecules (Figure 4a).
Landscape diversity was characterised by locally calculated pattern parameters from three categorical map layers (1 10 000 base map, 1 10 000 soil map, combination of these maps) and from six numerical variables (elevation, slope angle, four channels of a Landsat 7 ETM image).
We extended this model to calculate beam propagation through lenses by firstly calculating the illumination pattern of a slit on a lens, secondly the pattern on the opposite side of the lens, illuminated by the previously calculated pattern, and finally the distribution of the electro-magnetic field on a projection screen at the desired distance.
Right now, the device works something like a Nielsen survey -- it picks up a sampling of passing radios and then calculates patterns of listenership.
Petite and imperious, she built her "Seguiriya" out of clear shapes and calculated patterns, covering a lot of ground and using soft finger snaps like seductive whispers.
Experimental (dots) and calculated patterns; difference profiles and positions of the diffraction maxima are given.
The corresponding factors Rwp (4.69%) and Rexp (4.27%) indicate a relatively good agreement between the experimental and calculated patterns.
Small-angle X-ray diffraction patterns were recorded for a number of high-density polyethylene samples and were successively analysed by a fit with the calculated patterns corresponding to certain theoretical models.
The refinement results and difference plot for the observed and calculated patterns of NPs are shown in Figure 2. The refining factors of Rwp (8.07%) and Rexp (4.02%) indicate a good agreement between the experimental and calculated patterns.
