Abstract A dataset of (E)-N’-benzylideneisonicotinohydrazide derivatives as a potent anti-mycobacterium tuberculosis has been investigated utilizing Quantitative Structure-Activity Relationship (QSAR) techniques. Genetic Function Algorithm (GFA) and Multiple Linear Regression Analysis (MLRA) were used to select the descriptors and to generate the correlation QSAR models that relate the Mi...
soil moisture retention curve is one of the soil hydraulic prosperities which its direct measurement is time consuming and expensive. therefore, indirect methods such as developing pedotransfer functions have been used to predict this characteristic from soil readily available or easily measurable data. in this study, multiple linear regression method was used to develop point pedotransfer func...
there are three major strategies to form neural network ensembles. the simplest one is the cross validation strategy in which all members are trained with the same training data. bagging and boosting strategies pro-duce perturbed sample from training data. this paper provides an ideal model based on two important factors: activation function and number of neurons in the hidden layer and based u...
The accurate determination of river flow in watersheds without sufficient data is one of the major challenges in hydrology. In this regard, given the diversity of existing hydrological models, selection of an appropriate model requires evaluation of the performance of the hydrological models in each region. The objective of this study was to compare the performance of artificial neural network ...
Background & objectives: Content validity is the first type of validity that has to be ensured during the design of a tool. Its prerequisite for other validities and its close relationship with the tool reliability place it in a vital position in the questionnaire design. However, since it has not been paid enough attention in national publications therefore in this paper we will explain the di...
A bi-directional many-sided explanation typed multi-step validation method including its implementation architecture has been proposed to diminish validation loads for busy experts. This paper presents a validation tool based on this method. This tool supports the multi-step, bi-directional validation by experts, KEs (Knowledge Engineers) and computers on the Intra/lnternet environment. Particu...
Objectives: Successful aging is an interdisciplinary concept. Despite the great body of literature on successful aging, few studies have focused on its subjective and multidimensional measurements. Thus, the present study aimed to develop an instrument to measure self-perceived successful aging. Methods: We used a mixed method approach. The successful aging dimensions were explored through an ...
