This work uses a Geographical Information System environment and remote sensing data to assess the availability and sustainability of forest biomass residues in a management unit with around 940 ha of maritime pine forest.
The main effect of the former is the destruction of the forest and thus the reduction of future biomass residues availability.
The production data of a Portuguese pellets factory in Mortágua was used.
Results As it can be seen in Table 1, there was an overall reduction of the above ground biomass from 2004 to 2007.

Fig. 4(a) shows the raw data, which apparently include servo oscillation of X axis with 0.2 μm amplitude and 0.06 second cycle.
Thus, application of the MA filter was necessary to clarify the data.
Fig. 4(b) shows the same data with 10-points MA applied, in which the quadrant protrusions are more distinct compared to the raw data.
Note that for all of the following data, the same filter is applied.
Our future work will be to construct a method to fully utilize such gathered data to optimize machining parameters.

A common quantitative method, Rietveld refinement method was selected to analyze the X-ray diffraction (XRD) data [8].
Rietveld refinement method was used to analyze the collected data via Highscore Plus software, equipped with the JCPDS database.
All diffraction data was analyzed further by Rietveld refinement method to obtain crystallographic data involving lattice parameter, crystallite size and crystal structure.
The goodness of fit (GOF) were obtained represent the quality of refinement data.

The digital human model moves without individual angle and coordinates data of the respective segments joints.
The recording of transaction data of an employee has to be designed in a way that the recording can be made as uncomplicated as possible.
This implies that the process of data collection is short and the employee does not have to face additional barriers in the application.
In addition, anthropometric data, such as the length of the limbs and the body size will be recorded and stored.
The usage of collected anthropometric and the movement data leads to individual programming of properties and limitations in the human model.

Yamagishi [9] carried out a study on numerical analysis of the circumferential motion over a cylinder with textured grooves on which external face in large Reynolds number case, and found the cavitation occurred at the inner of texturing groove, simultaneously, the transition of cavitation was assigned from laminar to turbulent boundary layer, the reduction of the friction coefficient of texturing surface was performed.
The width w and depth hp of micro-groove have effect on load supporting capacity and friction reduction, here numerical results for them are showed in the name of net calculating forces, dynamic pressures, wall shear stress and related mean friction coefficient.
However, those datum don't offer us supporting for an explicit analysis based on various structures of micro isosceles trapezoid-grooves, thus a mathematic method of surface integral is used here.
The data of mean coefficient of friction for various micro arc-grooves are obtained by the mathematic method of surface integral for wall shear stress τ and total pressure pt loaded on sliding surface, which were shown in Fig. 6.

Tests were carried out to compare the reduction of noise levels from external sources with and without the chamber.
The results obtained suggest a clear reduction of noise levels with different wind speeds, and as expected, resulted with higher reductions at higher wind tunnel speeds. 1.
Open-jet wind tunnel, however, produces shear layer that allows the wind tunnel noise to propagate to the open room, which may produce uncertainties in the measured data.

The test results obtained show that the Fourier analysis is a convenient data processing technique in active thermal NDT.
(5) As a simple start point for further analysis, we can assume that the presence of subsurface defects can be simulated with reduction in material thickness.
Maximum differential temperature signal vs. defect size and depth (series 1: defect diameter 20mm, series 2: defect diameter 10mm, series 3: defect diameter 5mm) Conclusions The test results obtained show that the Fourier analysis is a convenient data processing technique in active thermal NDT.
