The wood hygroscopicity is a factor which plays an essential role in the chemistry of wood.
The access to the organic cell internal structure enabling the respiration process may occur gradually - enzymatically and in an accelerated form through mechanical-chemical means.

Fibers having active surface properties or suitable porous structure can be used as such or as a bioactive part in composites.
Mechanical properties can be improved with intensive heat-treatment, but it is obvious that biodegradation and bioactivity is reduced due to denser structures and decreased surface reactivity, respectively.

Meanwhile, compared with the traditional low-resolution remote sensing images, such as ETM+ and ASTER, WorldView-2 provides rich information in the shape, structure, texture, size, and location, which has obvious advantages in identifying geologic structure, distinguishing lithology, and reducing the influence of the mixed spectrum on object recognition.

Introduction Polymer and coating durability studies have been ongoing research for about 120 years [1].Polyurethane coatings provide corrosion protection for many different structures, such as storage tanks, oil and gas piping, water and wastewater pipelines, bridges, ships, and other marine facilities.
However, the selection, application, and inspection of a polyurethane coating can be a difficult task because of various attributes, including coating chemistry, coating properties, surface preparation requirements, application parameters, and resistance to environmental attack, economics, and worker safety [2].

The tensile properties decide the performance of post operations: spinning, warping, weaving and knitting and the properties of the final textile structure.
Since fibres are very long in relation to their thickness and since they are used mainly in the form of fabrics, or laminar structures that are thin compared with their area, the forces to which they are subjected in manufacture and use nearly always cause the fibres to stretch.

Or an unfolding method can be applied, which converts the three-way data into a matrix where all the original data is maintained in relation to its value but the three-way structure nature of the dataset is lost.
The three-way data analysis taking into account the true three-way structure of the dataset allows visualization of the hidden information, which can be jointly interpreted.
