PROBABILITY density functions of the involved random variables are essential for the reliability-based design of offshore structures. The objective of present research was the derivation of PROBABILITY density function (PDF) for the local joint flexibility (LJF) factor, fLJF, in two-planar tubular DK-joints commonly found in jacket-type offshore structures. A total of 162 finite element (FE) analyses were carried out on 81 FE models of DK-joints subjected to two types of axial loading. Generated FE models were validated using available experimental data, FE results, and design formulas. Based on the results of parametric FE study, a sample database was prepared for the fLJF values and density histograms were generated for respective samples based on the Freedman-Diaconis rule. Nine theoretical PDFs were fitted to the developed histograms and the maximum likelihood (ML) method was applied to evaluate the parameters of fitted PDFs. In each case, the Kolmogorov-Smirnov and chi-squared tests were used to evaluate the goodness of fit. Finally, the Inverse Gaussian model was proposed as the governing PROBABILITY distribution function for the fLJF. After substituting the values of estimated parameters, two fully defined PDFs were presented for the fLJF in tubular DK-joints subjected to two types of axial loading.

In the electronic warfare environment, radars can be differentiated according to intra-pulse and inter-pulse modulations. Detection of intra-pulse modulation with negative SNR is a topic of interest to researchers. In this paper separation of intra-pulse modulation with frequency and time-frequency methods is presented. Using this method, we can categorize different types of LFM, 4FSK, 2FSK, BPSK, and NM modulations. The algorithm of this method is based on characteristics and it is able to classify all radar signals from these types of modulations. To detect the modulation, time-frequency characteristics based on the improved time-frequency transform, B, have been used. The innovation in this research, is the use of new characteristics of time-frequency distribution. The proposed algorithm uses time-frequency distribution to analyze radar signals. Dimension reduction is performed next, then for each frequency the maximum time value is considered and the characteristics are extracted from signal. The presented algorithm has 100% capability of separating radar signals for this number of intra-pulse signals up to-11dB of SNR whereas similar methods have less accuracy with SNR range between-5db to 5db.

Two recent developments have come into the forefront with reference to updating the seismic design provisions for codes: (1) publication of new seismic hazard maps for Canada by the Geological Survey of Canada, and (2) emergence of the concept of new spectral format outdating the conventional standardized spectral format. The fourth-generation seismic hazard maps are based on enriched seismic data, enhanced knowledge of regional seismicity and improved seismic hazard modeling techniques. Therefore, the new maps are more accurate and need to incorporate into the Canadian Highway Bridge Design Code (CHBDC) for its next edition similar to its building counterpart National Building Code of Canada (NBCC). In fact, the code writers expressed similar intentions with comments in the commentary of CHBCD 2006. During the process of updating codes, NBCC, and AASHTO Guide Specifications for LRFD Seismic Bridge Design, American Association of State Highway and Transportation Officials, Washington (2009) lowered the PROBABILITY level from 10 to 2% and 10 to 5%, respectively. This study has brought five sets of hazard maps corresponding to 2%, 5% and 10% PROBABILITY of EXCEEDANCE in 50 years developed by the GSC under investigation. To have a sound statistical inference, 389 Canadian cities are selected. This study shows the implications of the changes of new hazard maps on the design process (i.e., extent of magnification or reduction of the design forces).

In some point of view, neither Michel Foucault nor Ibn Khaldun are considered philosophers in the conventional classifications, but both are very  important in intellectual and, of course, in philosophical contexts, especially for those who are interested in the deep study of human life from the perspective of political thought.The main concern of two thinkers, one in the 14th century, the other in the 20th century, is the issue  of power, although neither of them provided a precise definition of it. In this article, an attempt has been made to show the place of power and domination in the political thought of both thinkers by examining the thoughts of two thinkers. And in search of an answer to this question, how did Asabiyyah and industry of religion in Ibn Khaldun's thought and social control through self-technology and discipline in Foucault's thought lead to the expansion of the domination of power? This article is written by analytically comparing the opinions of two thinkers based on Ibn Khaldun's most important book called Muqaddimah and Foucault's late works

PM2.5 is an important indicator of air pollution. This pollutant can result in lung and respiratory problems in people. The aim of the present study was to predict number of PM2.5 EXCEEDANCE days using Hidden Markov Model considering Poisson distribution as an indicator for people susceptible to that particular level of air quality. In this study, evaluations were made for number of PM2.5 EXCEEDANCE days in Tehran, Iran, from Oct.2010 to Dec.2015. The Poisson hidden Markov model was applied considering various hidden states to make a two-year forecast for number of PM2.5 EXCEEDANCE days.We estimated the Poisson Hidden Markov’s parameters (transition matrix, PROBABILITY, and lambda) by using maximum likelihood method. By applying the Akaike Information Criteria, the hidden Markov model with three states was used to make the prediction. The results of forecasting mean, median, mode, and interval for the three states of Poisson hidden Markov model are reported. The results showed that the number of EXCEEDANCE days in a month for the next two years using the third state of the model would be 5 to 16 days. The predictedmodeandmeanfor the third months afterward at the third state were 11 and 11. These predictions showed that number of EXCEEDANCE days (predicted mean of 6.87 to 11.39 days) is relatively high for sensitive individuals according to the PM2.5 Air Quality Index. Thus, it is essential to monitor levels of suspended particulate air pollution in Tehran.

One of the most frequent rules in various areas of demonstrative jurisprudence of Two Major Sects of Islam religion is a rule that is known among Shīʿa as “tolerance in the evidence of traditions” (Arabic: التسامح فی أدلّة السنن) and in Sunnī as “latitudinarianism in documents” (Arabic: التساهل فی أسانید). Believers in the general application of this rule have based it for reasons such as consensus (Arabic: إجماع), tradition famous through practice (Arabic: الشهرة العملیّة), and rational judgement (intellectual judgement) and a group of aḥādīth (Arabic: أحادیث, plural form for ḥadīth, literally “talk” or “discourse”) called “Akhbar-e- Man Balagh” (Arabic: أخبار من بلغ). The understanding of the aforementioned narrations and the extent of application of this rule has caused a conflict of opinions among scholars. The narrations containing the excellences of suras of the Holy Book of Quran is one of the fields of application of the rule of tolerance. The present research has explained the types of exposure to this group of narrations based on the rule of tolerance by using descriptive-exploratory method and using library sources and seeks to find a suitable approach about narrations of the excellences of suras (chapters) of the Holy Book of Quran. The interaction with these narrations is organized based on a special reading of the rule of tolerance in the selected approach, which is based on a rational interpretation of the contents of Man-Balagh (Arabic: من بلغ)’s narrations and is compatible with the indications of some verses and traditions. The use of weak narrations containing the excellences of suras (chapters) will be permissible based on this approach considering three conditions and without any certainty of attributing these narrations to Sharʿ (Islamic rules).

How to profoundly change the beliefs of the polytheists during the age of revelation from the denial of the Prophet (pbuh) to the certainty of his Message and the acceptance of his full guardianship is a question worthy of attention. The order of verses about prophecy based on the order of revelation is the reason to lead a transformative process and a special Quranic method in institutionalizing the belief of prophecy in the lives of Arabs. In the first stage, the Holy Quran in the first Makkī (Arabic: المکّیّ, suras revealed in Mecca) chapters has prepared the community from the motivational side to accept the truth of the Prophet’s (pbuh) prophecy and briefly stating the key issues surrounding it. The Holy Book of Quran at the time of the emergence of oppositions and doubts (the second stage) destroyed the arguments of the polytheists and explained the prophecy and proved its authenticity from a cognitive perspective in the second stage by presenting clear arguments. and the Holy Book of Quran in the third stage after Madanī (Arabic: المدنیّ, suras revealed in Medina) period has undertaken measures in order to fulfill the goals of the Massage by explaining the true position of the Prophet (pbuh) to deepen and operationalize the Prophetic belief through explaining practical duties for the Prophet (pbuh) and behavior based on the acceptance of Walaya (Arabic: ولایة, meaning “guardianship” or “governance”).

The current research was conducted with the aim of identifying the employment competencies of educational graduates from the perspective of view of employers. This research was applied in terms of purpose and was among the qualitative researches of Grounded Theory type. The participants of this research included 24 employers in the field of educational (interviewers for the Education recruitment exam, directors of non-state educational institutes, directors and recruitment officers of non-state schools, directors of kindergartens and preschools) in Birjand city. Data were collected using semi-structured interview and analyzed by Strauss and Corbin method and using MAXQDA-2020 software. In order to validate the research, two methods of member control and peer review or feedback were used. Consecutive review and comparison of data resulted in the extraction of 28 categories and 6 themes. Data analysis led to the formation of a sub-theory. The model shows that the focal variable is the process of education and teaching skills. The focal variable, under the influence of contextual and intermediate conditions, leads to the formation of the strategies of "being a lifelong learner", "research skills", "planning skills", "classroom skills and classroom management", "purposefulness" and "problem solving skills". became Finally, "increasing employability" was the consequence of this process.

Considering the fact that the words in the intra-religious attitude are considered in two ways, the first is towards jurisprudential words and the second is a rational and conceptual view focusing on their meanings. we have tried to deal with one of the most important issues of intra-religious attitude with a rational approach by descriptive and analytical method, which is the category of "hermeneutic interpretation" of words, especially the most influential idea of interpretation & that is the view of the "spirit of meaning" of Ghazali. After Ghazali, Ibn Arabi used this theory of Ghazali regarding the development of meaning in creating his new idea, and by re-reading Ghazali's idea with a mystical approach, he presented his own theory regarding the expansion of meaning. While accepting the argument of the focal point of the theory of the spirit of meaning, he removes it from the exclusivity to the "linear", and for this purpose, he brought up arguments as well as the Conditions of Hermeneutic Interpretation in this regard. Ibn Arabi's arguments on transversal interpretation include new formulations in the argument, which after him, this theory was favored and accepted by Mulla Sadra, and then it was accepted by his students.
