Abstract Estimating growing stock is one of the main objectives of forest inventories. It refers to the stem volume of individual trees which is typically derived by models as it cannot be easily measured directly. These models are thus based on meas

Im Rahmen eines vom BMEL und der Fachagentur Nachwachsende Rohstoffe e.V. (FNR) geförderten Kooperationsvorhabens wurden in den Vegetationsperioden von 2015 bis 2017 die Beikrautfloren von sechs bedeutenden Kräuterarten erfasst. Kriterien für die

Long-term changes in growth, physiology and stand structure, as well as differences due to species composition, were examined in six types of Swiss plenter forests: (1) Picea abies dominated, (2) mixtures of P. abies and Abies alba, (3) mixtures of P

A quasi-steady doublet-lattice correction method is used to predict aerodynamic gust responses of two different configurations: a swept wing, the so-called Aerostabil wing, and a transport aircraft configuration, the NASA Common Research Model. The r

Forests dominated by European beech (Fagus sylvatica L.) are among both the most widespread in Europe and the most intensely exploited globally. One of the largest remnants of unmanaged beech forests in Europe is the Uholka-Shyrokyi Luh forest in Tra

Self-sustained shock wave oscillations on airfoils, commonly defined as shock buffet, can occur under certain combinations of transonic Mach number and angle of attack due to the interaction between the shock and the separated boundary layer. To help

Aeroelastic limit-cycle oscillations due to aerodynamic nonlinearities are usually investigated using coupled fluid–structure interaction simulations in the time domain. These simulations are compu...

In this work limit-cycle oscillations (LCOs) caused by aerodynamic non-linearities were analysed using fluid-structure interaction (FSI) simulations of a two-degree-of-freedom airfoil system. A comparison with sinusoidal forced motion oscillation sim
