Mazandaran province is one of the most important agricultural areas in Iran. Researches findings show that the role of bank credits is really important due to the lack of available funds in agricultural sector. In this study, the relationship between allocation of Agricultural Bank credits of Iran as professional bank section and agricultural employment was studied in the Mazandaran province ba...
این مقاله درصدد پاسخ به این سؤال است که آیا سیاستهای مالی انبساطی به صورت افزایش مخارج دولت و کاهش مالیات بر رشد اقتصادی در ایران به صورت خطی تأثیرگذار است یا غیرخطی؟ به این منظور، کارایی هر یک از برنامههای مذکور با بهکارگیری دو الگوی خودرگرسیون برداری خطی و آستانهای و اطلاعات سالهای ۱۳۳۸ الی ۱۳۹۱ بررسی شده است. در این ارتباط، هنگام استفاده از الگوی آستانهای، مشاهده های سالهای مورد بررسی...
Due to the important role of the boiler-turbine units in industries and electricity generation, it is important to diagnose different types of faults in different parts of boiler-turbine system. Different parts of a boiler-turbine system like the sensor or actuator or plant can be affected by various types of faults. In this paper, the effects of the occurrence of faults on the actuators are in...
In this study, detection and identification of common faults in industrial gas turbines is investigated. We propose a model-based robust fault detection(FD) method based on multiple models. For residual generation a bank of Local Linear Neuro-Fuzzy (LLNF) models is used. Moreover, in fault detection step, a passive approach based on adaptive threshold is employed. To achieve this purpose, the a...
The three-state agent-based 2D model of nancial markets in the version proposed by Giulia Iori in 2002 has been herein extended. We have introduced the increase of herding behaviour by modelling the altering trust of an agent in his nearest neighbours. The trust increases if the neighbour has foreseen the price change correctly and the trust decreases in the opposite case. Our version only slig...
Threshold models have gained much recent attention in applied economics for modeling nonlinear behavior. The appeal for these models is in part due to the observable pattern that many economic variables follow, such as asymmetric adjustment towards equilibrium. Recent developments in model specification derive error-correction models as a specific type of threshold models. This paper summarizes...
In this paper, a new multi-criteria decision-making procedure is presented, which captures preferential information in the form of the threshold model. It is based on the ELECTRE-like sorting analysis restricted by the localization principle, which enables high adaptability of the decision model and reduces the cognitive load imposed on the decision-makers. It lays the foundation for the introd...
Methods We compared four bioclimatic variables [actual evapotranspiration (AET), water deficit (DEF), mean temperature of the coldest month (MTCO), and growing degree-days (GDD5)] with the distribution of T. heterophylla at a 2-km grid cell resolution. The distribution is based on a zonal ecosystem classification where T. heterophylla is the dominant late-successional species. For each bioclima...
This paper investigates the co-integration and causal relationships by threshold model and non-linear adjustments relationship by STAR model between the U.S. and Taiwan stock market. The fi ndings indicate that there exists an asymmetric threshold co-integration relationship between the U.S. and Taiwan stock markets. Moreover, this paper further fi nds that this is signifi cant evidence of non-...
In this article we study the implication of thresholds in preferences. To model this we extend the basic model of John and Pecchenino (1994) by allowing the current level of environmental quality to have a discrete impact on how an agent trades off future consumption and environmental quality. In other words, we endogenize the semi-elasticity of utility based on a step function. We motivate the...
