background: it is estimated that major depression disorders constitute 8.2% of years lived with disability (ylds) globally. the repetitive transcranial magnetic stimulation (rtms) and electroconvulsive therapy (ect) are two relative common interventions to treat major depressive disorders, especially for treatment resistant depression. in this study the cost- effectiveness and cost-utility of r...
the aim of this study was to estimate suspended sediment by the ann model, dt with cart algorithm and different types of src, in ten stations from the lorestan province of iran. the results showed that the accuracy of ann with levenberg-marquardt back propagation algorithm is more than the two other models, especially in high discharges. comparison of different intervals in models showed that r...
قابلیّت ترکخوردگی تنشی دو رقم برنج هاشمی و خزر طی فرآیند خشککردن شلتوک مورد بررسی قرار گرفت. شلتوکهای هر دو رقم با دماهای هوای خشک کردن °c35، °c45، °c55 و °c65 بصورت لایه نازک (ضخامت لایة محصول به اندازة سه دانه) خشک شدند. واکنش توسعة ترکتنشی درون آندوسپرم دانههای آنها در گذر از رطوبتهای 18%، 15% و نهایتاً 12% بر پایة تر مورد بررسی قرار گرفت. برای کمّیکردن میزان شدت ترکهای توسعه یافته یا ...
In this paper, at first we define the concepts of response function and accessible states of a complete residuated lattice-valued (for simplicity we write $mathcal{L}$-valued) tree automaton with a threshold $c.$ Then, related to these concepts, we prove some lemmas and theorems that are applied in considering some decision problems such as finiteness-value and emptiness-value of recognizable t...
A new technique presents to improve the performance of dynamic voltage restorer (DVR) for voltage sag mitigation. This control scheme is based on cuckoo search algorithm with tree fuzzy rule based classifier (CSA-TFRC). CSA is used for optimizing the output of TFRC so the classification output of the network is enhanced. While, the combination of cuckoo search algorithm, fuzzy and decision tree...
One of the most common causes or credit phenomenon that is taken into account for credit risk is the customer’s noncompliance with the commitments. Thus, by predicting the behavior of loan applicants, the growth rate of debts can be decreased. Hence, this study is conducted on corporate applicants for loans in one of the public banks in Iran. In this paper, the main elements comprising the cus...
Efficiency is an issue of importance and interest to both managers of different organizations and customers who use the products and services of these organizations. The aim of this research is to study the efficiency of pharmaceutical companies accepted in the Stock Exchange Organization by using Window Data Envelopment Analysis (WDEA) and then, to provide some rules based on the decision tree...
Background and Aim: Neonatal jaundice is a matter that is very important for clinicians all over the world because this disease is one of the most common cases that requires clinical care. The aim of this study is to use data classification algorithms to predict the type of jaundice in neonates, and therefore, to prevent irreparable damages in future. Materials and Methods: This is a descripti...
we used various screening techniques, clustering, decision tree and generalized rule induction (association) (gri) models and molecular phylogenic relationship to search for patterns of halophi-licy and to find features contribute to halolysin salt stability. we found met was the sole n-terminal amino acid in halolysin proteins, whereas other amino acids found at this position of oth-er proteas...
Background and Objective: Unwanted pregnancy is a pregnancy that is considered to be unwanted by at least one member of the couple, and has adverse consequences for the family and community. Using four classification models, this study predicted unwanted pregnancy in the urban population of Khorramabad and compared these classification models. Materials and methods: In this cross-sectional s...
