    Get PDF
    The public life of people in most cases are among forgotten parts of the Persian literature; in other words, most of the poets because of their too much attention to the kings and their actions and behaviors, followed by their disconnection with the inferior class of the society, have rarely composed poems on the public life of the people. The constitutional revolution to a great extent shifted this balance in favor of the public. In this paper, the anthology of the Kurdish blind poet “Shami” - which deals with the poor class of the society and the issues relating to it from a linguistic and thematic perspective - has been investigated and on the basis of the issues that embody most in the anthology, the poems relating to the public life have been categorized into four groups: 1. Life appliances and equipment, 2.Number of people, 3. Speech and 4. Customs and etiquette. This investigation showed that Shami is a poet that understands the pains and woes of the people and tries through an eloquent language to express pains and sufferings of his own class in a poetic form, offering it to the public. Hence, he can be called a social poet as suc

    The forecasting of future value of water consumption in an urban area is highly complex and nonlinear. It often exhibits a high degree of spatial and temporal variability. It is a crucial factor for long-term sustainable management and improvement of the operation of urban water allocation system. This chapter will study the application of two pre-processing phase space reconstruction (PSR) and wavelet decomposition transform (WDT) methods to investigate the behavior of time series to forecast short-term water demand value of Kelowna City (BC, Canada). The research proposes two pre-process technique to improve the accuracy of the models. Artificial neural networks (ANNs), gene expression programming (GEP) and multilinear regression (MLR) methods are the tools that considered for forecasting the demand values. Evaluation of the tools is based on two steps with and without applying the pre-processing methods. Moreover, autocorrelation function (ACF) is used to calculate the lag time. Correlation dimension is used to study the chaotic behavior of the dataset. The models’ relative performance is compared using three different fitness indexes; coefficient of determination (CD), root mean square error (RMSE) and mean absolute error (MAE). The results showed how pre-processing combination of WDT and PSR improved the performance of the models in forecasting short-term demand values

    In today’s digital world, the information systems are revolutionizing the way we connect. As the people are trying to adopt and integrate intelligent systems into daily lives, the risks around cyberattacks on user-specific information have significantly grown. To ensure safe communication, the Intrusion Detection Systems (IDS) were developed often by using machine learning (ML) algorithms that have the unique ability to detect malware against network security violations. Recently, it was reported that the IDS are prone to carefully crafted perturbations known as adversaries. With the aim to understand the impact of such attacks, in this paper, we have proposed a novel random neural network-based adversarial intrusion detection system (RNN-ADV). The NSL-KDD dataset is utilized for training. For adversarial attack crafting, the Jacobian Saliency Map Attack (JSMA) algorithm is used, which identifies the feature which can cause maximum change to the benign samples with minimum added perturbation. To check the effectiveness of the proposed adversarial scheme, the results are compared with a deep neural network which indicates that RNN-ADV performs better in terms of accuracy, precision, recall, F1 score and training epochs

    Purpose: Children long-term involvement with cancer may have a negative impact on the quality of life their parents. Design and implementation of training programs for parents whose children have been diagnosed with leukemia, as the primary caregivers of children, will have a special significance and can contribute to better taking care of such children. The main purpose of the present study was to examine the impact of conducting group discussion, as care program training, on the quality of life parents whose children were suffering from leukemia. Methods: This quasi-experimental before-after intervention study encompassed two groups of parents (in total 41) of leukemia children. To collect data, a demographic questionnaire and the shortened version of SF-36 questionnaire were used to determine the quality of life of parents. Both groups completed the quality of life questionnaires before and two months after the intervention. Results: Comparison of the parents’ quality of life mean scores, obtained before and two months after training, showed that promotion in 6 domains of bodily pain, general health, emotional health, role limitation due to emotional problems, social functioning, and vitality were occurred. (P <0.05) Conclusions: Considering the important role of parents in taking care of children suffering from leukemia, introduction of care program training can be a positive step to help these parents and empower them to manage their children’s problems more systematically and will ultimately lead to improved quality of life of parents

    The potential use of nanoclay was examined to modify fluid transfer properties of medium density fiberboard (MDF). For this, Na+ montmorillonite (Na+MMT) nanoclay was added to urea formaldehyde resin to produce MDF. Then, the air permeability and mass diffusivity of MDF were evaluated. Scanning electron microscope (SEM) images and X-ray diffraction (XRD) confirmed a dispersion and exfoliation of Na+MMT in the modified MDF. The air permeability presented a systematic decrease with increasing nanoclay amount. This reduction agreed with the simple "tortuous path" model. The nanoclay had no effect on the mass diffusivity
