Real-world processes are often combinations of deterministic and stochastic processes. Soil failure observed during farm tillage is one example of this phenomenon. In this paper, we investigated the nonlinear features of soil failure patterns in a...

Nonlinear Dynamics and Chaos in Agricultural Systems
Kenshi Sakai
Elsevier Feb 2001 ISBN:0-444-50646-2
前著「カオス農学入門」の英語版であるが、構成および内容は大幅に書き換えられ、分量は倍になった。特に、時系列データに対する具体的な非線形解析法を詳細に解説した。数十点以下の少数の時系列データが一般的である生態系のデータに対しては、RSM法を紹介した。１０００点以上のデータを有する場合には決定論的非線形解析の実際を、トイモデルの例示からはじめて、実際のデータへの応用へと幅広く解説した。さらに、時空間変動のモデリングと、実時空間データに対する、解析法を提案した。農学分野をターゲットとしたカオス理...
