PCA of these 27 plants were performed based on RSCU of 59 synonymous codons, meanwhile variance contribution ratio, accumulated variance contribution ratio and quality of representation (cosα, α is the angle of spot vector and axial vector) were calculated using MATLAB (version 7.0) and drawn by OriginLab Origin (version 8.0, Microcal Software Inc., Northampton, MA, USA).
In these SOMs, the intensity of each spot represents the relative amount of surface area within the STM image with an {hkl} orientation defined by the position (distance and azimuth angle) of the spot relative to the central (001) spot.
Survey and high-resolution spectra were obtained using a 165 mm mean radius concentric hemispherical analyzer operated at a constant pass energy of 160 eV for survey and 80 eV for high-resolution scans (take-off angle of 90°, spot size of 150 μm × 150 μm).
The thickness of the surface layers was determined by the XPS depth profiling, layer by layer experiment, using Ar+ ion beam as an incident angle of 45°, with a spot size of 100 μm, on area of 3 × 3 mm.
Once fixed the angle of analysis, for samples spotted on Al-TEOS slide dried, the system is proportional to the concentration of the analyte in the sample and is linear in the range 1 nM–1 μM.
This contribution describes the modelling and testing of structural elements by application of an angle bar and spot welding techniques with the introduction of adhesive layers between adherends.
The diffraction spot position was directly related to the position and the angle of the incident beam, and thus the position information of the incident beam can be detected by the location information of diffraction spots.
Frankly, the map is too small — you have to do a good deal of zooming and panning to figure out what you're looking at — but at least it gives you a choice of road map, satellite view or aerial view (photos taken by airplanes from different angles of the same spot).
Properties of gas-powder mixture (gas type, feeding rate, etc)., relative positioning of workpiece, laser beam focal spot and tilting angle of gas-powder stream symmetry axis significantly influence the results of laser processing.
If there is no magnification factor between the eye's pupil and the pupil plane of the wavefront sensor, then the angle of elongation for the wavefront sensor spot on the edge of the pupil θ ' is the same as θ.
As the speaker vibrates, the angle of the mirror changes causing the spot on the wall to move.
