Mechanized tree planting in Finland and improving its productivity

Mechanized Mathematics and Its Applications

This paper describes optimization of the Takagi-Sugeno fuzzy model. To prove the existence of optimal control, we apply compactness of a set of membership functions in L space and continuity of approximate reasoning and show the existence of a pair of membership functions which minimize the quadratic performance function.

Species for Christmas Tree Planting in Virginia*

Christmas trees can be grown through out the state, and growers are located in all regions. Se lec tion of the proper species, however, is important. Soil conditions and gen er al climate are the primary considerations influencing species selection, but other characteristics, such as con sum er pref er ence, species characteristics and require ments, condition of the planting site, and the pres...

Efficiency of superabsorbents in improving water productivity

Agricultural residues and various other materials are currently being used as additives to improve the physical and chemical properties of soil. Iran is located in an arid and semiarid region, so using strategies to reduce water use will reduce the problem water scarcity. The use of superabsorbent to increase water uptake and retention is one of the solutions that have been applied to improve w...

Tree Planting in Indonesia: Trends, Impacts and Directions

Implementing Municipal Tree Planting: Los Angeles Million-Tree Initiative

Urban forests are increasingly being seen as an important infrastructure that can help cities remediate their environmental impacts. This work reports on the first steps in implementing a million tree program in Los Angeles and the ways such a biogenic-living-infrastructure has been approached. Numbers of studies have been done to quantify the benefits of urban forests, but little has been writ...
