On solving periodic Riccati equations [PDF]
Numerically reliable algorithms to compute the periodic non-negative definite stabilizing solutions of the periodic differential Riccati equation (PRDE) and discrete-time periodic Riccati equation (DPRE) are proposed. For the numerical solution of PRDEs,

A long-term comparison of different silvicultural systems was established in 1923 in central Sweden, in an uneven-aged mixed Norway spruceâScots pine forest ( (L.) Karst. â L.) with about 85% spruce and 15% pine. The five treatments consisted of two

Locally periodic unfolding method and two-scale convergence on surfaces of locally periodic microstructures [PDF]
In this paper we generalize the periodic unfolding method and the notion of two-scale convergence on surfaces of periodic microstructures to locally-periodic situations.

CARBON STOCK GROWTH IN A SECONDARY ATLANTIC FOREST [PDF]
The secondary Atlantic forests play an important role in the context of climate change, acting as a carbon sink for the atmosphere. However, these forests can become a carbon source in case of increased tree mortality.

Impact of regional climatic conditions on tree growth on mainland Greece
Forest growth is commonly used to explore tree vitality and ability to resist to environmental changes or climatic fluctuations. This paper illustrates and examines how regional climatic conditions can be related to the decline of tree growth, which were
