using linear variable differential transformer (LVDT) through a computer controlled data acquisition
system.

The dielectric loss factor
(tanδ) and capacitance (C) were examined by LCR meter (TH2828A, Tonghui electronics), and the
capacitance data were converted to the relative dielectric constant (εr) related to the disc thickness (t)
and electrode surface area (S)], using the classic relationship C=εrS/t.
Fig.3 Percentage of tetragonal and rhombohedral phases in PSZT ceramics with various barium contents According to the data from the XRD patterns, the lattice parameters (cT, aT, cT/aT) for T phase and (dR/aR, where dR is the diagonal of the rhombohedra) for R phase in the PSZT ceramics can be calculated using the least square method.
It is observed that εr increases almost linearly with the barium content range of 0.14 to 0.22 and then exhibits a reduction tendency.

This results in the cost reduction in fabrication and launches effectively, as well as improving the system performance.
Testing data of the optical surface contour map will be transformed into fabrication file after the completion of optical aspheric profilometry.
Interferometry with null lens technology will be suitable for supplying the surface testing data during the optical polishing.

Wang et al proposed Kernel maximum scatter difference (KMSD) methods, which is a two stage KPCA plus MSD method [3].However, for dimensionality reduction, it fails to find the essential structure of the samples space with nonlinear distribution by using MSD.
In fact, in face recognition task, the dimension of face data is very high, which will consume much memory and time.
Secondly, we also compare the performance of proposed method with other methods for varying number of training samples. p (p=2,3,4,5,6) images are randomly selected from each class to construct the training data set, the remaining images being used as the test images.

An average conductivity data was determined from five replications at different locations on each sample.
The reduction in strength and elongation at high CB content was caused from an agglomeration of CB particles, low interaction between CB-NR surfaces and high void volume, resulting to a discontinuous phase material [6].
According to the data as shown in Fig. 2., similarly to many previous studies of NR/CB the compression set was significantly increased with increasing CB loading both at 25 °C (unaging) and 70 °C (aging).

Compared to current practice, the use of 100% untreated scrap gives a substantial reduction in the life cycle impacts (20% at the least, up to almost 90%), and greenhouse gas emissions almost halved over the life cycle of the component.
Looking at the cost data in the right-most column in figure 2, we find that the shredder and separation processes could carry a small yet potential cost savings.
These data do not include all costs of the logistics and sorting processes, thereby underestimating the real costs of the sorting strategies.

Through the test and data analysis of fabric odor removal, hygroscopic, heat accumulation function , various functions effects of the coffee yarn knitted fabrics under different fiber proportions has been discussed,it is important for the development of multi-effects and good wear ability of knitted fabrics.
Ammonia reduction rate calculation formula is: K = (a-b) / a ( K is ammonia decrease rate , a is the initial ammonia concentration in tank, b is the ammonia concentration 12 hours later).
Summary 1) For Fabric odor removal performance, it shows from the experimental data, along with coffee yarn content increase from 30% to 40%, ammonia removal rate become lager from 30.7% to 36.6%, When coffee yarn content is 40%, the odor removal performance of fabric is best, odor removal rate reach to 36.6%. 2) With the increase of coffee yarn content, the fabric hygroscopic tended to increase, absorbent quick-drying performance enhance.
