Forgings are characterized by symmetry and various values of reduction ratio coefficient (d=D/d) of rolled steps.
Geometrical parameters of impressions place data segments for forging rolling were determined on the basis of sizing method according to Smirnov [9].
Moreover, for both analyzed variants it was assumed that forgings would be made from titanium alloy Ti6Al4V, for which rigid-plastic material model was taken from data base of the software Simufact Forming [10].
A common feature of forgings rolled by two methods is large heterogeneity of strains, both between particular steps (which is obvious due to various reduction ratio values) as in the area of single steps, rolled with the same reduction ratio.
A reduction gear with variably rotating output shafts enabling torque measurement.

Fuel efficiency can be improved by an engine with high performance, the reduction of air
resistance and the rolling resistance of a tire, the compact of a car body, as well and weight
reduction; Thus, a large number of studies on the methods for reducing the weight of automobile
parts have been actively conducted [3-9].
The most imperative factor regarding the weight reduction are an strength of parts for variations of shapes and dimensions, because the plastic deformation and fracture of the parts are caused by the reduction of strength resulting from the change of the shapes and dimensions when considering only weight reduction [3-7, 9].
The die casting machine is equipped with a shot control system that provides real-time data [9].
This is because the laminar flow of the reheated material is caused at the injection velocity below 0.5 m/s. (3) On the basis of the experimental results for A356 materials for a variety of the injection conditions, a quantitative data base for the purpose of setting the optimal injection conditions like injection velocity and applied pressure was constructed.

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.

And the data will be realized multi-hop transmission.
According to the key’s information, the terminal device send data through invoking function from ZigBee protocol stack.
An AF_INCOMING_MSG_CMD OSAL handles the data received in coordinator device.
The coordinator node handles the data packet through the AF_INCOMING_MSG_CMD OSAL.
If the timer starts, the pin’s edge signal(rising edge, falling edge) will trigger the counter to count and store the data in register accordingly.

These tests are simulated using an initial set of data, arbitrarily chosen.
Material data.
Material data in case of isotropic hardening [K, N, mm, MPa] Temp.
For the second set of data, the shear parameter N of the Hill’s law, which cannot be correctly defined by a tensile test alone, is combined to the Swift law data and the back-stress parameters to be fitted by the inverse method.
For confidential reasons, these data are not specified here.

Data acquisition and processing
In order to more accurately reflect the growth status of wetland vegetation, the phase of remote
sensing images was chosen as the vegetation growing season.
Data base uses the WGS84 geographic coordinate system and UTM projection.
In addition, to improve the interpretation accuracy of wetland landscape types, during the process of interpretation, we also mainly refer to some data, objects' photographs and video information of field investigation, some pieces of 1: 50 000 topographic maps and historical survey maps and data coming from the late 80s to early 90s of the last century, covering topography, land use, vegetation, and soil type.
If the amount of a certain type transferring to the others is larger than the others transferring to it, it will have a reduction, otherwise it will have an increase.
The results show that the bare muddy tidal flat kept reducing from 2001 to 2008, and the reduction from 2001 to 2004 was greater than that from 2004 to 2008.

Dramatic improvements in the quality of the electrochemical data can be
obtained with these electrodes.
Voltammograms for the reduction of duroquinone in acetonitrile obtained at a 6.2 µm radius hemispherical mercury electrode are shown in Fig. 1.
Because of the reduced iR drop, microvoltammetric electrodes allow quantitative data to be obtained from cyclic voltammetry at scan rates of 20,000 Vs-1 and qualitative data up to 100,000 Vs-1 [11,12].
In addition, they are simple to use, comparatively inexpensive and data interpretation is relatively straightforward.

The reliability of the obtained data
were checked by comparison with the temperature dependent Hall effect measurements using the
van der Pauw technique.
The reduction by two orders of magniude was a maximum.
These data indicate that Ce presence in the melt leads to the incorporation of Ce 3+ ions into the host InP lattice.
For comparisons are also shown the corresponding data for bulk InP doped with Zn, which has binding energy 43 meV.
