abstract geopedology is a systematic approach of geomorphic analysis for soil mapping which focuses the field operation mainly on sample area. the purpose of this study is to determine the credibility of generalization of the results of geopedological approach for similar landforms in the borujen region, using diversity and similarity indices in a soil taxonomic hierarchical structure. after a ...
large impervious surfaces and man-made waterways are the characteristic of urban area. increasing urbanization and rapid growth of cities in recent decades towards the upstream watershed, has been severely affected on rainfall-runoff processes in urban area. therefore, to computer models in order to illustrate these processes the proper design or assessment of urban drainage systems has special...
مقایسۀ نقشه های حساسیت زمین لغزش با استفاده از مدل رگرسیون لجستیک (LR) و مدل عمومی تجمیع یافته (GAM)
Landslide is one of the most common natural disasters that endanger the lives and properties of people in mountainous areas. Therefore, identification of risk exposure areas of landslide is essential to prevent and reduce damages by landslides. The purpose of this study is compared to logistic regression (LR) and generalized additive models (GAM) and the evaluation of their performance for land...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
In the last two decades several deterministic models for predicting fire behaviour have been developed. One of the most common fire growth model is the computer program Farsite (Finney, 1998), based on the Rothermel’s original fire spread equation. Farsite describes the spatial and temporal spread and behaviour of fire under different terrain, fuels, and weather conditions. It is currently used...
In analyzing a DNA mixture sample, the measured peak areas of alleles of STR markers amplified using the polymerase chain-reaction (PCR) technique provide valuable information concerning the relative amounts of DNA originating from each contributor to the mixture. This information can be exploited for the purpose of trying to predict the genetic profiles of those contributors whose genetic prof...
Background and objective: Landslide susceptibility zoning using different methods is one of the landslide management strategies. The purpose of this study is to evaluate the landslides susceptibility in the Bar watershed in Khorasan Razavi province using the support vector machine (SVM) algorithm. Method: First, the landslide layer of the area was corrected through field visits and Google Earth...
Context: Software Product Line Engineering (SPLE) has emerged as a thriving approach for software products constructions. In SPLE, a triumphant software product is highly reliant on the validity of an SPLE. Hence, validation is a significant process within SPLE. Objective: In this paper, we reviewed the related works in the area of automated validation of SPLE to bring to light the pros and con...
The Static-99 is a widely used actuarial risk assessment instrument. Various international validation studies have found satisfactory to good predictive validity for the Static-99, with the area under the curve (AUC) between 59% and 95%. This study is the first evaluation of the predictive accuracy of the Static-99 among sex offenders in Switzerland. The Static-99 scores of 69 violent/sex offen...
