Due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. The known world class Cu-Mo deposit, Sarcheshmeh Porphyry deposit (central Iran) selected as the study area. The Hypogene zone of the deposit was chosen as the space in which estim...
on one hand, oil is the greatest energy resource in the world and, on the other hand, because of the role of oil revenue in the economic of oil producer countries, such as iran,it is vital for these countries. so it is necessary to recognize different affective parameters on oil market for these countries. in this research, we try to forecast oil price as an important variable in world wide oil...
In this article, we consider the growth of microorganisms on mixtures of carbon sources and characterize the consumer-resource relationship for this system. The characteristic features observed for the growth of a single microorganism on a pair of carbon sources allow a representation of this relationship based on a general paradigm for resource classification. This representation is verified u...
This paper analyzes conservation and extinction of renewable resources when the production function is nonconcave and the return function depends on consumption and the resource stock. The paper focuses on the efficiency of global conservation, a safe standard of conservation, and extinction. Which outcome obtains depends on the marginal rate of substitution between investment and the stock in ...
We discuss an analytically tractable discrete-time dynamic game in which a finite number of players extract a renewable resource. We characterize a symmetric Markov-perfect Nash equilibrium of this game and derive a necessary and sufficient condition under which the resource does not become extinct in equilibrium. This condition requires that the intrinsic growth rate of the resource exceeds a ...
We analyze oligopolistic exhaustible-resource depletion when firms can trade forward contracts on deliveries, a market structure prevalent in most resource commodity markets. When market interactions become arbitrarily frequent, all stocks are contracted and subgame-perfect equilibrium allocation becomes perfectly competitive. The result is in contrast with the idea that forward markets can hel...
We study amortised resource analysis in the context of term rewrite systems. We introduce a novel amortised analysis based on the potential method. The method is represented in an inference system akin to a type system and gives rise to polynomial bounds on the innermost runtime complexity of the analysed rewrite system. The crucial feature of the inference system is the admittance of multivari...
In this short paper, uncertainties on resource stock and on technical progress are introduced into an intertemporal equilibrium model of optimal extraction of a non-renewable resource. The representative consumer maximizes a recursive utility function which disentangles between intertemporal elasticity of substitution and risk aversion. A closed-form solution is derived for both the optimal ext...
In this paper we address the problem of multilingual part-of-speech tagging for resource-poor languages. We use parallel data to transfer part-of-speech information from resource-rich to resourcepoor languages. Additionally, we use a small amount of annotated data to learn to “correct” errors from projected approach such as tagset mismatch between languages, achieving state-of-the-art performan...
The paper deals with rent-seeking behaviour among agents competing for future shares of a common renewable natural resource. Rent-seeking might become profitable when the agents expect that the distribution of the natural resource in future periods will be dependent on the agents’ extraction of the resource in the past, even though high exploitation might reduce the stock that future individual...
