Kamath, A.C. (author), Gard, W.F. (author), van de Kuilen, J.W.G. (author)Timber sheet pile walls are widely used for the protection of stream banks in different parts of the world. However, there is a tendency to create more sustainable types of stream banks not only because exploitable wood is more difficult to obtain, but also because of disturbance to the natural habitat of plants and animals due to hard...journal article 2020

Khaloian Sarnaghi, A. (author), Rais, A. (author), Kovryga, A. (author), Gard, W.F. (author), van de Kuilen, J.W.G. (author)Samples of European beech (Fagus sylvatica) were used for this study. Logs of these samples covered a scatter of mild-to-strong curvatures and the boards of these samples covered strong fiber deviations. This study consists of two separate parts: (1) log reconstruction and optimization of the cutting pattern, and (2) board reconstruction and...journal article 2020

Wang, X. (author), Gard, W.F. (author), Borska, Helena (author), Ursem, W.N.J. (author), van de Kuilen, J.W.G. (author)The integration of buildings into vegetation has become a necessity in many metropolitan areas of the world today. It expands the potential of vertical and horizontal, exterior and interior, exposed and enclosed spaces in a building that can be used to accommodate plants. Green infrastructures have benefits both on urban and building scales....journal article 2020

Kovryga, A (author), Chuquin Gamarra, J. O. (author), van de Kuilen, J.W.G. (author)Strength grading is an important step for the production of homogenous and high-quality solid wood material. In particular, for hardwoods, the use of non-visible characteristics is indispensable. Dynamic MOE (E<sub>dyn</sub>) is an important parameter widely used for grading of softwoods and applicable to hardwoods as well. There are two...journal article 2020

Kovryga, A. (author), Khaloian Sarnaghi, A. (author), van de Kuilen, J.W.G. (author)Detection of local wood inhomogeneities is important for accurate strength and stiffness prediction. In hardwood specimens, visual characteristics (e.g. knots or fibre deviation) are difficult to detect, either with a visual surface inspection or by the machine. Transversal ultrasound scan (TUS) is a non-destructive evaluation method with...journal article 2020

Ravenshorst, G.J.P. (author), Gard, W.F. (author), van de Kuilen, J.W.G. (author)The main parameter that influences the bending strength of timber from tropical hardwood is the slope of grain. Although, in the grading rules, a specific threshold value is given, in these hardwoods, the global slope of grain is very difficult to quantify by visual assessment. The slope of grain measured after testing gives a better...journal article 2020

Khaloian Sarnaghi, A. (author), Rais, A (author), Kovryga, A. (author), Gard, W.F. (author), van de Kuilen, J.W.G. (author)Wood is a strongly anisotropic and heterogeneous material with natural defects that are affecting the uniform scatter of the fiber patterns. European beech (Fagus sylvatica) is the species, used for this study. The logs of these species have generally complicated shapes with frequent curvatures, which is in contrast to most of the softwood...conference paper 2019
