Short-wavelength behavior of transmitted radiation in endlessly single-mode microstructured fibers
was investigated in details /3/ and explained as fundamental mode leaking due to reduction of mode
spot and thereby reduction of effective modal refractive index contrast between core and cladding.
Our and reference data concerning the localization of bend-induced losses boundary are summarized in the Table 1: Table 1 .
We obtained the experimental data for half-divergence angle and compared them with calculated data α determined by formula: α = λ/πw, where w - mode spot radii.
All data are composed in the Table 2: Table 2 .
Summary Above mentioned experimental data and estimations have led us to the thought that in the most considered cases theoretically multimode microstructured fibers, containing 7- or 19-element cores, in practice serve as single-mode ones in the spectral region of several hundred (up to one thousand) nanometers in width.

Main Line Running Tests
In order to find out base data for the time reduction of KTX where express lines and conventional
lines of Kyungbu line meet, Korean express trains ran faster than current speed record on the
connection of express lines and conventional lines.
Also, when 15 km/h speed was added, derailment coefficient gages had problems, data at that speed were not acquired.
We measured and analyzed the data only in case of leading axle running.
There were 10~30 seconds time reductions.
There should be further tests to acquire data.

To validate the model, the experimental data and computed curves of effective stress and grain size were compared.
The reason is that neck reduction takes place before the tension failure.
The data mainly includes the grain growth/refinement data, initial grain size, and stress-strain relationships at different forming conditions.

The predicted results from the damage constitutive equations were validated through the comparison with experimental data.

Abstract.
Introduction Recently aluminum is widely used in data line material for thin film transistor (TFT) because of its low resistivity to overcome RC delay in large area liquid crystal display (LCD).
Aluminum data line corrosion of TFT-LCD in such out-door environments is a problem of growing importance.
Pitting of aluminum data line leads to open circuits in interconnection by electrolytic dissolution in an aggressive environment [1].
Since conversion coating reaction occurs with the dissolution of the base metal, in application of conversion coatings to the thin film materials, the reduction in the thickness of base metal film should be minimized during conversion coating process.

In addition, the approaches to the post-processing experimental data, obtained in the form of torque-twist angle curve, are reviewed.
The post-processing of obtained experimental data can be carried out with the use of modified Nadai method.
The issues of post-processing the experimental data obtained during testing specimens in torsion are discussed in [17, 18].

Hence, the focus of this research is to analyze the effect of microwave pre-treatment (MP) and pressure cooker pre-treatment (PCP) parameters on OPEFB lignin reduction.
The focus of this research was to analyze the effect of microwave pre-treatment (MP) and pressure cooker pre-treatment (PCP) parameters on OPEFB lignin reduction and to maximize the cellulose content and lignin reduction after the pretreatment process and hydrolysis by fungal treatment in the waste of Oil Palm Empty Fruit Bunches (OPEFB).
Lignocellulose Content of OPEFB after Pressure Cooker Pretreatment Time (minute) Cellulose (%) Hemicellulose (%) Lignin (%) Lignin Removal (%) Raw Material 26.25 30.10 29.52 - 20 32.20 33.18 24.04 18.57% 40 43.22 17.81 20.18 31.63% 60 36.09 26.24 17.94 39.22% The data (Table 2 and Table 3) show that pressure cooker pretreatment gave the best results.
The data obtained for the cellulose content and glucose levels of the sample fungal treatment 2 (FT-2) process are presented in Figure 6 and Figure 7.
Glucose Content Improvement after Fungal Treatment 2 (FT-2) Conclusions The best lignin degradation process occurred in OPEFB samples with pressure cooker pretreatment at 60 minutes with lignin content as much as 17.94% and lignin content reduction of 39.23%.

Graphene can be formed by the reduction of graphene oxide (GO), resulting in reduced graphene oxide (rGO).
The XRD data are obtained by using CuKα radiation with λ=1.5406 Å , showing the broad peak at 2θ ~24º as similar as the graphene peaks[13], thus these materials so-called as graphenic-like carbon (GC).
If we compared the interlayer distance with the thickness data that we got from the SEM cross-section, it shows that the graphene-like carbon (GC) sheets still consist of many layers.
For the detail data about the thickness in varying time deposition shown in Table 1.

The developed chip serration model is in good accord with the experimental data, demonstrating that the empirical model could be used for further chip morphology and chatter analyses.
Such strategies include reduction of spindle speed and feed rate to stay within the stability zones [3], magnetostrictive actuator equipped tool with PID controller [4], and active chatter control techniques using online sensors and actuators to stay within the machining stability lobes [5] etc.
The data acquisition system consisted of an accelerometer (Kistler 50g), for vibration data acquisition; a Dewetron module, for signal conditioning; and a National Instruments DAQ card (model: PCI-6023E), for interfacing with the Dell workstation.
A small CCD model, consisting of 3 factors and 5 levels, was developed in RSM using DOE software to model chip serration frequency from empirical data.
