Review of published toughness data for N06022 material provided
information similar to that shown in Table 1.
Therefore, a normalization of general applicability is needed to formulate correlations to relate subsize data to conventional full size data.
This model works very well and yields miniature specimen Upper Shelf Energy (USE) data within 1 J of conventional data.
This model fits the data very well as shown in Fig. 1 up to 8 mm, and then varies linearly beyond that thickness.

Though analyzing the data of simulation results, the mathematical relation between interfacial heat transfer coefficient and potential and kinetic energy shows the trend of direct proportion.
Introduction The developments of electronic packaging technologies are driven by the need of automation, miniaturization, reduction in cost and environmental impact.
The data of this mesh from simulation results were taken to analyze the relation of interfacial heat transfer coefficient.
By analyzing the data of simulation, the potential energy and kinetic energy suffered on the substrate is proportional to the value of interfacial heat transfer coefficient.

Injury severity by age groups based on data of Korean expressway has been studied.
The data contains general accident data such as the time and place of the accident occurrence, the characteristics of the suspect and the victim, the types of accidents, etc.
The accident data is then tabulated.

We present resonant x-ray scattering experimental data from YVO3.
Furthermore, it is suggested that through this transition there is a brief reduction of the crystal symmetry, resulting in a complete loss of intensity in the (010) ATS reflection.

Therefore, the purpose of this study lies in acquiring quantitative design data that can be put into the practice by comparing and evaluating the strength degradation under the environment where the moisture is absorbed by conducting static and impact collapse test after setting extreme condition for CFRP composite that takes consistent form such as frontal side members that is actually used in vehicle.
As a result of this study showed that the strength reduction of about 50% appears due to moisture absorptions.

Reduction of labor costs with an increase in the reliability of information about the state of damage and technical condition is an actual scientific and practical task.
The response of the structures to the vibrational load can be measured and used to assess the state of the structure based on the dynamic characteristics extracted from the measurement data.
First mode shape of construction with a defect and corresponding value of natural frequency Modeling and analysis of parameters in ANSYS are calculated to simulate the acquisition of measurement data from accelerometer sensors mounted on a physical system (construction) on a small number of points.

In general, this parameter has been found by varying it to minimize the sum of the squared deviations between the actual and predicted data.
According to the data reported in Table 1 we can see that water absorption for the composites is higher than for the matrix.
Table 1 - Moisture content and geometric data for the water sorption in vegetable fiber reinforced composites (30% w/w fiber contents).
Numerical results of average moisture content of the composites under investigation were compared with the experimental data.
Data comparison indicates that the model employed here is appropriate because the good agreement obtained in all studied cases.

The product design 3D model contains not only the geometrical data of product, but may contain a part of the process plan and technological data as well.
The target is to gain experience in these fields at the level of a manufacturing system as a unit. [8] The whole FMS (all manufacturing and handling devices) must therefore contain a communication structure based on modern industrial standard that is compatible also with other industrial facilities to enable trouble free data transfer.
In this reason, we have now activity about a material flow data collection.
One from the visual method for data collection are described at [11] Advantage of this method is a very fast (real time) data collection without a construction modification in the manufacturing system.

All data is acquired
non-intrusively so that no interference of the flow field by the measurement is to occur.
These data fields give valuable insight into unsteady flow topologies and their interaction with model structures.
In the PIV data there are pronounced secondary vortices present, starting at the leading edge of the airfoil.
This, however, will require the development of tools for fast alignment and calibration of the experimental set up and on-line evaluation, for comprehensive post-processing and data reduction tools in order to compare and analyze experimental and numerical data during the test, and for easily understandable presentation of the results to the end user.

Strain Potential Method: This is one of the earliest methods developed to estimate seismic deformation [8], by combining the results of linear or equivalent linear analysis and the laboratory data.
Stiffness Reduction Method: Another method developed by Seed and his co-workers is stiffness reduction approach [7,13].
The method takes into account the strength and stiffness reduction due to pore pressure increase during the shaking and it also able to incorporate the residual strength after liquefaction.
Probabilistic Seismic Hazard Assessment The site specific seismic hazard assessment comprised several tasks, including data review and collection, fault mapping and trenching, earthquake source characterisation, ground motion attenuation, probabilistic seismic hazard analysis (PSHA) and ground motion assessment.
Attenuation relations for shallow crustal earthquakes based on California strong motion data.
