With these, the product design and manufacturing cycle has shown time reduction [1].
Registration of CMM and optical scanning data In a combined method, data collection using a touch probe and an optical scanning probe must be transformed into one common coordinate system.
Data merging When the registration has been performed, the data from a touch probe overlaps with the triangular mesh model.
When the weight of the smallest edge is larger than a given threshold, this graph reduction ends.
The sampled data of cylinder is used to simulate the data acquired by CMM (sparse data at left) and optical scanner (dense data at right), as shown in Fig. 2(a).

To date no experimental data is available about the dynamic temperature profile for refinery sludge gasification in an updraft gasifier.
In order to measure the temperature profile inside the gasifier and classify the gasification reactions zones, five type-K thermocouples connected to data logger (USB TC-08) and the readings of the temperature are logged in the computer.
In gasification, reduction reaction is the prefered.
Combustion is also important as it sustain the endothermic reduction reaction.

By data-mining through large amounts of datasets, we showed that CNTs with small diameter, large number of walls, and crosslinks between walls can have high nominal tensile strength.
Data Mining with SOM With the ability of visualizing and categorizing information of materials, SOM is an integrated tool for material research [20].
The data mining approach with SOM aims to decrease the complexity of high-dimensional data, and reduce the high-dimension data to two-dimensional data.
To further understand the overall relation between geometrical properties of chirality, diameter, wall, crosslink and geometrical properties, we use SOM to dig on our data shown as Fig. 7.
Summary The relationship between mechanical properties and geometrical properties of CNTs were investigated by high-throughput molecular simulation and data mining technique.

However, few reports can be found focusing on the study of high-solid anaerobic digestion of sewage sludge, and no data were available on the start-up performance of high-solid anaerobic digestion at mesophilic temperatures.
The performance data of the first 20 days indicated that starting OLR should be controlled to avoid VFA accumulation above 3 g/l.
With OLR increased from 2.0 to 3.0 kg VS m-3d-3, the methane yield decreased from 0.266 (average of the data in Fig.1 a from day 50 to 59) to 0.231 l CH4 g-1 VSadded-1 d-1 and the VS reduction decreased from 42.2% (average of the data in Fig.1 a from day 70 to 85) to 33%.
a b c Fig.1 Performance data of semi-continuous reactors with designed fed-sludge TS of 10%(a), 15%(b) and 20%(c).
As focusing on start-up period, there is shown the performance data at the same OLR but different TS in Fig.4.

The residual Young’s modulus data are presented in terms of normalized quantities.
Furthermore, establishing and interpolating of constant life diagram data using these methods is a tedious task, since they require a large collection of stress-life data to suit various wire rope designs.
These much-needed fatigue-life data are usually based on the data taken from available standards such as DNV OS-E301 [13], and the available literatures which are very limited.
The life data of the steel wire ropes at the various fatigue loading conditions is shown in Fig. 6.
The fatigue strength-life (S-N) data of the drawn steel wires is shown in Fig. 8.
