Trees, seeds and seedlings analyses in the process of obtaining a quality planting material for black locust (Robinia pseudoacacia L.)

open access: yesNotulae Scientia Biologicae, 2020
Black locust (Robinia pseudoacacia L.) was among the first North-American tree species imported in Europe. In Romania, black locust has established itself as a forest tree appreciated for multiple uses. The objective of the hereby study was to identify a

Effects of phenotypic selection on height-diameter ratio of Norway spruce and Scots pine in Sweden

open access: yesSilva Fennica, 2018
Genetically improved Norway spruce ( (L.) Karst.) and Scots pine ( L.) are extensively used in operational Swedish forestry plantations. However, relatively little is known about the stem slenderness (height-diameter ratio) of genetically improved ...

Evaluation of plus trees in cocoa (Theobroma cacao L.) for growth, flower, yield and yield contributing characters during the initial growth phase

open access: yesElectronic Journal of Plant Breeding, 2019
The aim of this study was to evaluate the plus trees of cocoa for growth, flower, yield and yield contributing characters during the initial growth phase. Thirty five (35) plus trees in two different farmer’s field were recorded for their growth, flower,

Mapping Species Composition of Forests and Tree Plantations in Northeastern Costa Rica with an Integration of Hyperspectral and Multitemporal Landsat Imagery

open access: yesRemote Sensing, 2015
An efficient means to map tree plantations is needed to detect tropical land use change and evaluate reforestation projects. To analyze recent tree plantation expansion in northeastern Costa Rica, we examined the potential of combining moderate ...

On the Parameterized Intractability of Monadic Second-Order Logic [PDF]

open access: yesLogical Methods in Computer Science, 2012
One of Courcelle's celebrated results states that if C is a class of graphs of bounded tree-width, then model-checking for monadic second order logic (MSO_2) is fixed-parameter tractable (fpt) on C by linear time parameterized algorithms, where the ...

Collaborative Cost Multi-Agent Decision-Making Algorithm with Factored-Value Monte Carlo Tree Search and Max-Plus

open access: yesGames, 2023
In this paper, we describe the Factored Value MCTS Hybrid Cost-Max-Plus algorithm, a collection of decision-making algorithms (centralized, decentralized, and hybrid) for a multi-agent system in a collaborative setting that considers action costs.
