Selecting energy efficient inputs using graph structure [PDF]
Selecting appropriate inputs for systems described by complex networks is an important but difficult problem that largely remains open in the field of control of networks. Recent work has proposed two methods for energy efficient input selection; a gradient based heuristic and a greedy approximation algorithm.

Energy production of poplar clones and their energy use efficiency
The poplar clones of Robusta and I-214 (Populus × euramericana) are characterized by fast growth and high quality biomass production. The calorific values for these poplar clones were determined, and modelling of calorific production of the entire poplar
