A Prioritization Model for the Immunization of Accident Prone Using Multi-Criteria Decision Methods and Fuzzy Hierarchy Algorithm Computational Research Progress in Applied Science & Engineering ©PEARL publication, 2017 ISSN 2423-4591 CRPASE Vol. 03(03), 123-131, September 2017 A Prioritization Model for the Immunization of Accident Prone Using Multi-criteria Decision Methods and Fuzzy Hierarchy Algorithm Hasan Ziari, Amir Amini, Amir Saadatjoo, Sayyed Mohsen Hosseini, Vahid Najafi Moghaddam Gilani School of Civil Engineering, Iran University of Science and Technology (IUST), Tehran, 16846-13114, Iran Keywords Abstract Immunization, Suburban accidents are more significant than intercity accidents in terms of both material Correction potential, and spiritual damages due to the vehicle’s high velocity. Based on the statistics, the mortality Accidents intensity index, rate in suburban routes accounts for more than 69% of total casualties caused by accidents Multi-criteria decision in Iran. In this study, it has been attempted to determine a model for assessing and making, prioritizing the immunization of accident prone sections of Qazvin-Abyek-Zanjan highway Fuzzy hierarchy algorithm. using various methods such as economic analysis, accidents intensity (RSI), Bayesian probability in accident prediction, AHP-GIS and AHP-Fuzzy. The results showed that the ranking of the accident prone sections’ correction is affected by the type of pattern and indicators used to assess the safety of the sections. Finally, with the implementation of fuzzy hierarchy algorithm, using the survey of safty specialists and determining the weights of input factors to the model by the expert choice (EC) software and fuzzy function, a comprehensive model is presented for assessing and prioritizing the correction of incidental events. According to the model’s acheivements, Buin Zahra-Rahim Abad three way with BSIP index of 0.596 meets the highest correction prioritization among the different sections, while Qazvin-Buin Zahra section has the lowest one with the BSIP index value of 0.148. between the cost and accidents intensity. suburban accidents 1.

During the recent years, due to the inappropriate status of During the recent years, various studies have been carried road accidents in Iran, many actions have been carried out to out on the subject area of traffic safety and prioritization ensure the safety of traffic and improve the performance of correction of the accident prone sections in the world and in the transportation industry. The average annual cost of road Iran. accidents and their damages is estimated as 1% of the gross In 2007, Moreno and his coassociates investigated and national product for the low income countries. This value is identified the incidental points by implementing Bayesian calculated as 1.5% for the medium income countries and 2% multi-criteria methods. The aim of that study was to rank the for rich ones and those with high incomes. The annual cost specified areas and determine the place or point of danger in of the accidents is estimated over than 518 billion US dollars detaile as well as accurate review as the first step in around the glob from which nearly 65 billion dollars is the improving the transportation safety. In this research, two portion of low income and medium income countries [1]. methods of Bayesian structure are imployed including the Based on the available statistics, the mortality rate in Bayesian test with weights (BTW) and Bayesian test suburban routes constitudes more than 69% of the total controlling for the posterior false discovery rate (FDR) or casualties due to the accidents of Iran.

Regarding population, social, economic, health, cultural, infrastructural, transportation and communicational indicators in 25 cities of Qazvin province, Qazvin, Abgarm, Narje are most developed, and KhakAli, Sagez Abad, Aavaj, Abgarm, Zia Abad, and Sirdan, are deprived cities, respectively. Coefficient of variance model indicates the most inequality belongs to cultural indicator and the least belong to social indicators. Based on the results of the study, economical factor is more effective on spatial structure of all cities in Qazvin. Moreover, infrastructural and cultural factors are influential in cities of the province.

This study was carried out for maize at Abyek area with 16618 ha. Soil and climate data were collected from 61 soil profiles at research farms and bagh kousar climatological Station, respectively. Maize growth of landscape, soil and climate requirements were determined using Sys et al tables and qualitative suitability classification of this crop was done by parametric square root method. The results showed that the study area climate was highly suitable for maize. Based on parametric square root method, 24.19% of the area S1, 37.28% S2, 29.53% S3, 5.26% N and 3.74% are NS for maize. In addition, soil depth, gravel percentage, lack of organic matter, salinity, alkalinity, and gypsum are important limiting factors in the area. Keywords: Land suitability, FAO, Square root.

  • The Impact of Climate Variability on Water Footprint Components of Rainfed Wheat and Barley in Qazvin Province of Iran†
    THE IMPACT OF CLIMATE VARIABILITY ON WATER FOOTPRINT COMPONENTS OF RAINFED WHEAT AND BARLEY IN QAZVIN PROVINCE OF IRAN† RASTA NAZARI1, HADI RAMEZANI ETEDALI1, BIJAN NAZARI1 AND BRIAN COLLINS2 1Department of Water Sciences and Engineering, Imam Khomeini International University, Qazvin, Iran 2The Centre for Crop Science, The University of Queensland, Toowoomba, Australia ABSTRACT Due to the shortage of precipitation, rainfed farming is facing numerous challenges in Iran. Understanding the impact of climate variables on the production of rainfed crops in each region is of utmost importance for dry farming. Based on the 11-year (2004-2015) data from synoptic stations in Qazvin province of Iran, a comprehensive simulation analysis was conducted with AquaCrop-GIS to study the yield and the green and gray water footprint (WF) of the main rainfed crops (wheat and barley) along with the correlation of the target variables (yield and WF components) with the selected climate variables. Based on the estimated values of green and gray WFs, planting of rainfed wheat and barley in Qazvin and Moalem Kalayeh stations with lower total WF will be more beneficial than in other stations. Regression analysis showed that in most stations, reference evapotranspiration had a direct effect on wheat total WF (TWF) while precipitation has a positive effect on barley TWF in Qazvin and Moalem Kalayeh. The regression equation of barley green WF in the Qazvin station showed the highest correlation with climate variables (R2 = 0.98). TWF of wheat and barley in Buin Zahra had the highest correlation with climate variables (R2 = 0.73 and 0.85, respectively).

Abstract: This paper deals with distribution data of 53 species of Iranian digger wasps from 27 genera and three families, Ampulicidae (single species), Crabronidae (28 species, 16 genera) and Sphecidae (24 species, 9 genera). Eight species are new records for the fauna of Iran: Bembix diversipes F.

Keywords: Ampulicidae, Crabronidae, Sphecidae, fauna, distribution, Iran Introduction The fauna of Iranian digger wasps has poorly been studied so far. The first work on this taxon was done by de Gussakovskij (1933), and after that many other contributions have been published: Beaumont (1957, 1970), Esmaili & Rastegar (1974), Ebrahimi (1993a, 1993b, 2000a, 2000b, 2005, 2008), Ebrahimi et al.

ABSTRACT In order to investigated the effects of soil type, source of P fertilizers, sulfur with thiobacillus applications on Olsen-P and inorganic P fractions in the experiment a greenhouse study as a 2*4*2 factorial experiment in a complete randomized design was performed with three factors of soil at 2 levels, P application at 4 levels and sulfur with thiobacillus at 2 levels and with 3 replications. The treatments were incubated for one year under FC moisture conditions. Effect of soil levels, P fertilizer sources and sulfur with thiobacillus application on inorganic P forms was significant during this time. Ca2-P increased in Ammonium phosphate and triple super phosphate treatments. Increase of Ca8-P in ammonium phosphate treatment was more than triple super phosphate treatment and sulfur with thiobacillus application decreased P fixation in soil after 80 days.
