the selection of erp systems has been considered as one of the most influential and risky managerial decisions due to its heavy burden of purchase and implementation costs. the purpose of this paper is designing a fuzzy expert system for selecting the appropriate erp system based on the internationally selected and validated criteria for minimizing the risks of inappropriate selection. if an op...
dexsy2 is a dental expert system, which diagnoses oral diseases and offers a treatment course. the system which is designed and implemented from scratch is capable of diagnosing among thirty five oral diseases and offering a course of treatment for each. it uses a decision tree for its representation of knowledge, and each of its nodes contains a frame. the knowledge base of the system contains...
KuhSefid Flourite deposit is located about 110 km south east of Mashhad. Geological units of the region related to Kashafroud Formation with Jurassic age. Most of fluorite mineralization can be seen along the faults with direction of north west-south east. Fluorite veins are differente in diameter of 2 to 2.5 m and length of 50 m. Hydrothermal solutions with maximum and minimum temperatures of ...
South coast of India is known as the high-level background radiation area (HBRA) mainly due to beach sands that contain natural radionuclides as components of the mineral monazite. The rich deposit of monazite is unevenly distributed along the coastal belt of Tamil Nadu and Kerala. An HBRA site that laid in 2×7 m along the sea was found in the beach of Chinnavillai, Tamil Nadu, where the maximu...
Mahour polymetal deposit located west of Nehbandan, east-central Iran, formed in hypabyssal acid rocks. Mineralization occurs along a three-km-long vein. Three zones have observed in the ore, downward: 1) leached zone marked by malachite, azurite, hematite, goethite and limonite, 2) supergene zone characterized by bornite, covellite, and chalcocite, and 3) Hypogene zone containing magnetite, ch...
In this research work, the frequency domain (FD) of surface geochemical data was analyzed to decompose the complex geochemical patterns related to different depths of the mineral deposit. In order to predict the variation in mineralization in the depth and identify the deep geochemical anomalies and blind mineralization using the surface geochemical data for the Dalli Cu-Au porphyry deposit, a ...
It is related to the realization of the benefit of state-owned resources and the long retainable development of the country to evaluate the mining property rights to improve the using rate of the mineral resources. Guided by the principle of prospective return, a method for evaluating geological potential value was put forward which emphasized on the valuation of geological techniques. A coeffi...
The Mazra'eh Shadi is located about 130 km northeast of Tabriz (NW Iran) in the Arasbaran metallogenic belt. The deposit occurs as a series of veins within the Eocene andesites. Mineralization shows epithermal system that controlled by fault distribution. Epithermal textures within the veins include comb, vaggy quartz, cockade, boxworke, plate calcite and breccia. Pyrite is the main ore mineral...
In vitro solubility testing is an important means of assessing the likely behavior of fibers that are respired and accumulate in the lung. The problem has been that such tests often do not mirror the dissolution and removal mechanisms seen in vivo. Comparison of iron and silica solubility values of various types of mineral fiber showed no obvious correlation. Treating a mineral fiber containing...
