the present study was conducted to determine the most appropriate tree species planted in the same ecological condition considering different variables at darabkola forest, mazandran province. for this purpose, the success of planted species (maple, walnut, oak, pine, ash and elm) was assessed according to ninecriteria (soil nitrogen, soil phosphorus, soil potassium, leaf nitrogen, leaf phospho...

conflagration of forests and rangelands is one of the most frequent events in iran. it is regarded as one of the most important parts of land degradation that occurred due to range destruction and desertification. this study was conducted in boroujerd, lorestan province in west of iran in 2013 to determine the fire risk model. the data prepared for the study area involved the vegetation types, ...

a suitable location plays an important role in the competitiveness of a plant inthe market and should be selected such that it allows access to strategic advantagescompared with other competitors. the aim of the current study was identificationoptimized location of fluting paper plant from agricultural residues in mazandaranprovince using the analytical hierarchy process (ahp). after performing...

it is commonly recognized that knowledge is the only source of core competence of environmental projects in the knowledge based companies, but the productivity rate of knowledge workers is always low. based on knowledge workers’ characteristics, in this paper, we seek to identify knowledge workers factors influencing on the environmental projects risk management success (eprm), then knowledge s...

landfill site selection is an important action in integrated solid waste management process. different criteria should be considered in site selection. therefore using special methods are necessary to evaluate the criteria. the object of the current study was to determine and select suitable sites for solid waste landfill in shiraz city regarding the observation of environmental matters by usin...

Abstract As the number of artificial intelligence (AI) applications increases rapidly and more people will be affected by AI’s decisions, there are real needs for novel AI systems that can deliver both accuracy explanations. To address these needs, this paper proposes a new approach called eXplainable Mapping Analytical Process (XMAP). Different from existing works in explainable AI, XMAP is hi...

We investigate the directed random walk on hierarchic trees. Two cases are investigated: random variables on deterministic trees with a continuous branching, and random variables on the trees constructed through the random branching process. We derive renormalization group (partial differential) equations for the branching models with binomial, Poisson, and compound Poisson distributions of ran...

A model for investigation of the optimal economic life cycle of grass leys with winter damage problems in northern Norway and the threshold of winter damage before it is profitable to reseed grasses is presented. A 2-level hierarchic Markov process has been constructed using the MLHMP software. The model takes uncertainty concerning the yield potential, damage estimation and weather dependent r...

This paper discusses the proof theory, semantics and meta-theory of a class of adaptive logics, called hierarchic adaptive logics. Their specific characteristics are illustrated throughout the paper with the use of one exemplary logic HK, an explicans for reasoning with prioritized belief bases. A generic proof theory for these systems is defined, together with a less complex proof theory for a...
