Controlling Complex Dynamics in a Protected Area Discrete-Time Model

Controlling Complex Dynamics in a Protected Area Discrete-Time Model

This paper investigates how the introduction of user fees and defensive expenditures changes the complex dynamics of a discrete-time model, which represents the interaction between visitors and environmental quality in an open-access protected-area OAPA . To investigate this issue more deeply, we begin by studying in great detail the OAPA model, and then we introduce the user fee β and the defe...

Controlling Complex Systems Dynamics without Prior Model

Controlling complex systems imposes to deal with high dynamics, non-linearity and multiple interdependencies. To handle these difficulties we can either build analytic models of the process to control, or enable the controller to learn how the process behaves. Adaptive Multi-Agent Systems (AMAS) are able to learn and adapt themselves to their environment thanks to the cooperative self-organizat...

Suitability determining in protected area for wildlife (Case study: Geno protected area)

Introduction: Rangelands constitute almost 52 percent of the country area computed as 164 million ha. The extent of rangelands has been estimated 84 million ha in Iran and they have been classified as good, moderate to poor and poor to very poor ones ranged as almost 10, 42 and 48 percent, respectively. One of the fundamental problems concerning land uses of rangelands is that Rangeland are not...

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
