    Abstract: Machine learning based forest management is disclosed. A set of input data related to a forest stand is accessed. A forest management plan defining at least one forest management activity for the forest stand is determined based on the accessed set of input data and at least one forest management preference. The determining of the forest management plan for the forest stand is performed by applying a parameterized policy to the accessed set of input data. The parameterized policy has been trained via a machine learning process using a forest development related simulation model.

    Abstract: Temperature responsive phase change bio-complexes (PCBC) with tunable physicochemical properties and preparation method thereof. The phase change bio-complexes consist of a phase change material (PCM) (or mixture of PCMs) and a polysaccharide (or combination of polysaccharides). The polysaccharide provides mechanical and thermal stabilization and the PCM provides temperature responsive properties to the complexation. In order to undergo complexation with polysaccharides, sugar alcohols and salt hydrates classifications of PCMs are preferred which results in compatibility and homogeneity of the bio-complexes. Addition of multivalent cations (water soluble salts) and/or salts of an acid tunes the thermophysical properties of the bio-complexes such as tunable temperature and latent heat of fusion and structural and thermal stability. These environmentally benign phase change bio-complexes can be applied in different form-stable formats such as powdered, films, pellets, sheets, beads, sponge etc. for thermal management purposes including thermal energy storage and thermal protection via heat absorbing-releasing, for instance, in building, packaging, electronics, temperature sensitive items (black boxes) and wearables.

    Abstract: The inventive device is a mechanical wave inducing device being connectable to a needle. The device has a displacement source and a driving signal connection part in order to connect the displacement source to a signal source. The device has also two connections parts, which are connected to the displacement source, and which each wing part has a connection point to be attached with the needle. The wing parts are converters in order to convert longitudinal mechanical wave movement created by the displacement source into transversal mechanical wave movement for the needle, and at least one connection point is designed to match the transversal mechanical waves to the needle.
