Generally, photochromic diarylethenes undergo reversible photoinduced cyclization/cycloreversion reactions between two isomers upon irradiation with UV and visible light, and the two isomers of diarylethenes differ from each other not only in their absorption spectra, but in many physical and chemical properties including geometry, refractive index, as well as oxidation/reduction potential, etc [5,6].
As shown in Figure 4, the quality of images recorded in 1c/PMMA film showed a clear contrast and without cross talk, which are important in rewritable data storage.
The optical storage experiment showed that the diarylethene derivative can be use as a data storage medium.

The present existing problems of industrial meters
Arrange available data, extract useful information, define information we need to know.
Because enterprises and institutions increase equipments according to their own conditions step by step, manufactures always allocate meters to meet customers' requirements, and most manufactures deem to keep secret of their technical know-how, finally the following situation of industrial meters comes into being: ①numerous manufactures, numerous meters, large consumption, different standards. ②for the reason that meter operation and maintenance needs a lot of worker personnel, it leads to waste graveness of human resources ③lower equipment compatibility, used inefficiently , overlapping investment, numerous maintenance worker personnel of manufactures, high costs and big energy consumption. ④this situation is not conducive to manufacture health competition , reduction of meters costs and development and renewal of meters. 2.
Draw up detailed communication protocols for accomplishing conversion between control and module, specify Baud rate, format and checking methods of data communication.

Spectral response and electrical characteristics
of the TPV cells fabricated on the base of such double heterostructures are improved due
to reduction of GaInAsSb surface recombination velocity [3] and photon recycling effect.
XRD data showed that FWHM values were lower for the structures grown on GaSb surface treated only in HCL.
The XRD and TEM data on the grown epilayers are indicative of the excellent materials quality and flat interfaces.

The reduction results in
changes in the static and dynamic behavior of the structures.
The ease of experimentation and data processing of vibration based detection methods make them attractive from an engineering perspective.
For the prediction of crack details from these data, a program has been written in MATLAB based on the theory given earlier.

Faced with this situation, most investigators have opted for empirical regression models fitted to measured data.
That is, (8) Only limited experimental data is available from the published literature on which to base a model for this phenomenon.
Given the time between stands and the mean value of temperature and stress, an approximate estimate of the width reduction due to creep for low carbon steel may be written as: (9) (10) Where, c1, c2 and c3 are material class dependent.

Morphing transformations
Starting from the recent studies from the big universities and research centers (Bristol University, NASA, DARPA) we can establish a classification of the morphing concept (figure 1): omni-morphing (internal morphology with multiple non planar dynamic volume); active poly-morphing (local multidirectional geometrical modifications and the wing is aero-elastic active: sliding wings, telescopic wings, folding rotating wings, folding wings); passive poly-morphing (local multidirectional geometrical modifications); active mono-morphing (local multidirectional geometrical modifications: interconnected flaps with flight stabilizer, spoilers, weight reduction of the wings, variable volume, variable chord wing, vectorial traction); unidirectional and discreet mono-morphing (local multidirectional geometrical modifications: discreet spoilers as controlled surfaces, flaps)[1].
Example of sensors (figure 2) and collected data: weather (temperature and humidity), biometrical (the quality of the atmosphere-smoke, gas, contaminated atmosphere), navigation (GPS), telemetry (speed, altitude, pressure), attitude (the position compared to other objects, the position/form of the wing at every moment).
Data for morphing angles morph 00 morph 100 morph -100 Conclusions The special UAV missions require exceptional evolutions from UAV (evolutions at small speeds, small turns, and quick maneuver).

Efficiency of cutting processes is defined by possibilities of subsequent after-forming of
preforms by longitudinal or cross-section upsetting for reduction of shape distortions.
The temperature and strain rate dependences of flow stress and shear viscosity for the 6063 aluminum alloy were found by approximation of experimental data (Fig. 2,a - solid lines).
As a result of analytical studies and summarizing of published data, authors have also designed mathematical models of characteristics of some die steels for hot stamping of aluminum alloys in a wide interval of temperatures.

Performance analysis of variable-speed compressor inverter driven has been studied extensively based on experimental data.
All of the experimental data were recorded at steady state.
The reduction of evaporator capacity can be improved while power consumption of compressor reduces apparently owing to the better superheat controlled by TEV.
