A Laser Doppler Vibrometer (LDV) (OFV303, Polytec) was used to measure the vibration of the test model and a DSP board (DS1103, dSPACE) for the data acquisition and controller implementation.
(2) The flutter control results in time and frequency domains are given in Fig. 9 which shows significant reduction in vibration level (up to 60dB in frequency domain and over 80% in time domain).

Past research on the process-induced deformation of composites was mainly focused on the springin of angled parts, i.e. the reduction in the enclosed angle.
The effective CTE and spring-in were studied by a Monte Carlo method. 1000 fiber volume fraction and ply angle data were randomly generated and the corresponding effective CTE and spring-in were calculated.

Test Results According to the experimental data, the relationship between the fatigue life (Nf) and the loading strain range (Δεt) on the log-log scale were shown in Fig.2.

In order to further analyze vibration behavior rule, then a set of data is given as Table 1.
Pendulation reduction in boom cranes using cable length manipulation.

This reduction in the emission current reduces the local electric field at the tip surface or equivalently the shielding effect due to the charge particles.
Therefore, our experimental and simulation data both clearly demonstrate that the space–charge effect due to the emitted electrons is important in determining the field-emission current from a nano-emitter in the present configuration.

Results and Discussion Roughness analysis shows that, in accordance to data obtained, the surface quality varies with feed, so that the minor feed produces minor roughness.
This phenomenon produces an effective reduction of polarization resistance.

Lately, small magnetic particles have been utilized for high-density data storage, xerography, magnetic-resonance imaging, sensors, ferrofluids, magnetic filtering, magnetic hyperthermia, and medical applications [1].
This iron-oxide layer can include up to 20 % of all iron atoms, it is not ferromagnetic and leads to reduced magnetic properties of the nanoparticles due to reduction of the unbound, magnetic active iron atoms [2].

Experimental data indicate that this process causes acceptable reductions in phenol, chemical oxygen demand (COD).

The important data controlling precipitate morphology are the lattice parameters of t-ZrO2 and c-ZrO2 at the temperature where precipitation is occurring.
The reduction increases the ionic radius of the cerium ions from 0.101nm for Ce 4+ to 0.111nm for Ce 3+, causing a mismatch in ionic radii with Zr 4+, resulting in high elastic lattice strain[7, 8].

DLAR coatings Whereas a SLAR coating can be designed to achieve zero reflectance at one wavelength, a DLAR coating offers a further reduction in reflectance.
Since the reflection coefficient needs to be minimised where Fi(λ) and Qi(λ) have their maximum values, the weighted reflectance Rw is calculated from Ref. [9]: (8) Silicon substrate is considered absorptive and the dispersion law is taken into account using data from Refs. [10, 11].
