Even at a lower temperature of 80ºC (with 80 min immersion) compared to 100ºC (with 30 min immersion), the reduction in thickness is approximately 70% compared to 58%.

Qualitative data via visual observation of the wafers’ surface after etching show that the wafers appear to have a surface roughness that may be good enough for further microfilter fabrication using FIB.

This decrease occurred in two of the measurement lines y = 0.85 and 1.00 mm (2 lines / 7 lines) and this reduction level was about 150 HV from x = 0 mm to x = 5 mm.

It possess Harvard structure whose instruction bus and data bus are separate, can accommodate 14-bit instructions, 8-bit data, two command lines, so that all 33 items of instructions are monocycle except for program jump instruction.
Therefore, the reduction of PIC16C770 system frequency (not affecting system performance), can reduce power loss.

It implies that Ramp Loss function prohibits the false negative examples (noise data) from becoming SVs.
In experiment, the two datasets are divided into four sub-datasets: MNIST 0~4 VS 5~9 (MNIST-0), which is digits 0~4 versus the digits 5~9; MNIST 1 VS others (MNIST-1), which is digit 1 versus all other digits; INRIA NOISE (INRIA-N), which is added 10% label noise; INRIA SOURCE (INRIA-S), the original data without any noise.
The main reason is that it is based on the SGD algorithm, which is only to compute a gradient of one example in each iteration, so it results in the great reduction of the computing time.

A 2 mm incisal reduction was made using flat-end and round-end tapered diamonds at a minimum of 1.2 mm for labial, palatal, and proximal surfaces.
The Zi-Ceram Zirconia cores were made at milling machine according to scanned data at Dental Graphics Co., Seoul, Korea.
The data in this study showed all the marginal gaps of specimens were within clinically acceptable limit so that differences between groups are negligible clinically.

Introduction In comparision with finite element method (FEM), the boundary element method (BEM) has unique advantages of dimension reduction and high accuracy.
Because the matrix-vector product is obtained derectly by tree data structure.
We choose the inverse of the block diagonal matrix corresponding to the leaves of the tree data structure[17].

Conventional RSSI-based mesh router selection approach leads to unfavourable association among the available mesh routers, causing large amount of data converge on single node, and thus, the load imbalance.
In Ref[5] the author divides the handoff procedure in MAC layer into 3 phases, and finds through experiments that discovery phase takes up about 80% of total handoff delay, basing on which, the author attains the reduction of the discovery delay by using the neighbour graph to record the associated places, as proposed in Ref [9].

The tensile strength was 1010MPa, the 0.2% yield stress was 920MPa, the reduction of area was 38% and the Vickers hardness was 306.
Fig. 2 shows the S-N data for different -values .
Concerning a quantitative evaluation for different types of notches, the experimental data was examined in view of the -parameter model.

Finally the powders were annealed at 1300 °C for 2h in a reducing atmosphere (5% H2 and 95% Ar) to ensure complete reduction of Eu 3+ to Eu 2+.
The XRD pattern shows clear monoclinic phase diffraction peaks of parent CaAl2O4 and are matched well with JCPDS data file No. 23-1036.
The lattice parameters calculated from XRD data are matching with the literature values [11].

Affected shipping vessels will have an increase of weight, subsequent potential speed reduction and loss of manoeuvrability thus will require a frequent dry dock cycle which is costly and time consuming.
Sample positioning and data acquisition took place automatically, with droplet side profiles being recorded for data analysis.
