assigning premium to the insurance contract in iran mostly has based on some old rules have been authorized by government, in such a situation predicting premium by analyzing database and it’s characteristics will be definitely such a big mistake. therefore the most beneficial information one can gathered from these data is the amount of loss happens during one contract to predicting insurance ...
heavy metals removal from polluted wastewater is one of the major concerns due to their harmful effectson human health and the environment. the aim of this study is to absorb cu2+ and co+2 ions from wastewater by means of a synthesized magnetite bentonite nono - adsorbent. initially, nano- adsorbent was produced by coprecipitation techniques. then, the resultant material was analyzed and evalua...
for the past 3 decades, creating industrial clusters have been considered as an approach for the development of most small and medium enterprises. the goal of this programme is that all small and medium enterprises locating in a certain geoghraphic area can concentrate on cluster approach to collaborate in market research, production design, training and other activities that are not economical...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
The presence of heavy metals (metals with a density of over than 5 g cm-3) in the soil surfaces, are mainly due to industrial and mining activities, fuel combustion, etc. Although some of the metals are essential elements for plants, in the high concentrations have toxic effects on plants. Some of the plants those grown in mining areas are resistant to high concentration of heavy ...
Facilitated by the achievements of various data mining techniques, both academic research and industrial applications are using data mining tools to explore knowledge from various databases. However, building a mining system is a nontrivial task, especially for a data mining novice. In this paper, we present an online interactive data mining toolbox − OIDM, which provides three categories (clas...
This paper describes the use of decision tree and rule induction in data mining applications. Of methods for classi cation and regression that have been developed in the elds of pattern recognition, statistics, and machine learning, these are of particular interest for data mining since they utilize symbolic and interpretable representations. Symbolic solutions can provide a high degree of insi...
Heuristic algorithms for mining large databases are being adapted to enable discriminatory analysis to be performed on biological data, accelerating the progress in understanding biological diversity and its industrial implications. A range of knowledge discovery algorithms are being applied to yeast characteristics data, providing new research leads and decision making tools. The research pres...
This paper describes successful industrial research and development in the area of underground coal mining equipment automation. A brief background to underground coal mining is given, and the process of longwall mining is detailed. Some of the major limitations and issues impacting on the productivity and safety of the longwall mining process are highlighted, which serve to motivate the automa...
