We are concerned with dynamic optimization processes from a viewpoint of Golden optimality. A path is called Golden if any state moves to the next state repeating the same Golden section in each transition. A policy is called Golden if it, together with a relevant dynamics, yields a Golden path. The probelm is whether an optimal path/policy is Golden or not. This paper minimizes a quadratic cri...

Genetic diversity as an important marker of the ecological status of aquatic ecosystems is considered a unique and powerful tool to evaluate biological communities. In order to evaluate the genetic diversity among golden mullet species (Liza aurata) in the southeast and southwest coasts of the Caspian Sea by D-Loop gene sequencing, a total of 23 fin specimens of golden mullet were collected fro...

We utilize the situation calculus to develop a logical model of hypertext systems. The work builds upon the earlier work of Bieber and Kimbrough in the logical modeling of hypertext systems. In our presentation, a particular version of the situation calculus (which includes a language for programming complex actions) developed for the modeling of dynamic worlds and for the control of robotic ag...

Mathematical models for the electrical activity in cardiac cells are normally formulated as systems of ordinary differential equations (ODEs). The equations are nonlinear and describe processes occurring on a wide range of time scales. Under normal accuracy requirements, this makes the systems stiff and therefore challenging to solve numerically. As standard implicit solvers are difficult to im...

Water quality management policies on a river basin scale are of special importance in order to prevent and/or reduce environmental pollution caused by human sources. Industrial effluents are a priority issue particularly in Urban Wastewater Systems (UWS) that receive mixed household and industrial wastewaters, apart from rainfall water. In this paper, we present an analysis and implementation o...

Shapiro et al. [2005; 2006], presented a framework for representing goal change in the situation calculus. In that framework, agents adopt a goal when requested to do so (by some agent reqr ), and they remain committed to the goal unless the request is cancelled by reqr . A common assumption in the agent theory literature, e.g., [Cohen and Levesque, 1990; Rao and Georgeff, 1991], is that achiev...

Courts assessing compensatory damages awards often lack adequate information to determine the value of a victim’s loss. A central reason for this problem, which the literature has thus far overlooked, is that courts face a dilemma when applying their standard information-forcing tools to the context of damages. Specifically, the standard method by which courts obtain information is through a bu...

Obligation change raises the “frame problem” which is to characterise what obligations remain unchanged after an action has been performed. Many general solutions have been proposed but even if they are attractive from a thoretical point of view they have practical draw-

since the 19th century, opium has been produced and consumed in the areas of asia, currently referred to as the golden crescent and the golden triangle (1). the golden crescent lies in south and southwest asia, including districts in the northwest frontier province of pakistan, the adjacent badakhshan area of afghanistan and the baluchistan area of iran. the area has been the scene of tradition...
