Accurate and reliable prediction of Perfobond Rib Shear Strength Connector is considered as a major issue in the structural engineering sector. Besides, selecting the most significant variables that have a major influence on PRSC in every important step for attaining economic and more accurate predictive models, this study investigates the capacity of deep learning neural network for shear strength prediction of PRSC. The proposed DLNN model is validated against support vector regression, artificial neural network, and M5 tree model. In the (...) second scenario, a comparable AI model hybridized with genetic algorithm as a robust bioinspired optimization approach for optimizing the related predictors for the PRSC is proposed. Hybridizing AI models with GA as a selector tool is an attempt to acquire the best accuracy of predictions with the fewest possible related parameters. In accordance with quantitative analysis, it can be observed that the GA-DLNN models required only 7 input parameters and yielded the best prediction accuracy with highest correlation coefficient and lowest value root mean square error. However, the other comparable models such as GA-M5Tree, GA-ANN, and GA-SVR required 10 input parameters to obtain a relatively acceptable level of accuracy. Employing GA as a feature parameter selection technique improves the precision of almost all hybrid models by optimally removing redundant variables which decrease the efficiency of the model.

The application of recycled aggregate as a sustainable material in construction projects is considered a promising approach to decrease the carbon footprint of concrete structures. Prediction of compressive strength of environmentally friendly concrete containing recycled aggregate is important for understanding sustainable structures’ concrete behaviour. In this research, the capability of the deep learning neural network approach is examined on the simulation of CS of EF concrete. The developed approach is compared to the well-known artificial intelligence approaches named multivariate adaptive regression (...) spline, extreme learning machines, and random forests. The dataset was divided into three scenarios 70%-30%, 80%-20%, and 90%-10% for training/testing to explore the impact of data division percentage on the capacity of the developed AI model. Extreme gradient boosting was integrated with the developed AI models to select the influencing variables on the CS prediction. Several statistical measures and graphical methods were generated to evaluate the efficiency of the presented models. In this regard, the results confirmed that the DLNN model attained the highest value of prediction performance with minimal root mean squared error. The study revealed that the highest prediction performance could be attained by increasing the number of variables in the prediction problem and using 90%-10% data division. The results demonstrated the robustness of the DLNN model over the other AI models in handling the complex behaviour of concrete. Due to the high accuracy of the DLNN model, the developed method can be used as a practical approach for future use of CS prediction of EF concrete. (shrink)

This article explores the various ways in which Muslims, in the past and the present, think about God. The article canvasses a range of views on questions and puzzles pertaining to the essence and attributes of God, the basis of God's Justice, the transcendence of God, and our ability to know and understand God. We encounter a diverse, and at times radically divergent range of views on how best to understand divinity within the tradition of Islam. Given the various conceptions (...) of divinity, available within the tradition, I develop an argument for the view that God is best understood as love. The view that God is love, I contend, emerges directly from the Quran, which is a document that sits at the very heart of the Islamic tradition. (shrink)

In this paper, I argue that Islamic theism is best explained by the hypothesis of Divine Commission, whereby Muhammad is viewed as being divinely commissioned to serve the overall salvific purposes of God. To this end, I present three observation reports relating to Islamic theism and evaluate HDC against an alternative hypothesis, the hypothesis of Non-Commission whereby Muhammad is not viewed as being divinely commissioned. I argue that the probability of the observation reports is greater on the assumption that HDC (...) is true than on the assumption that NC is true. Accordingly, this gives us reason to prefer HDC as a better explanation of Islamic theism. (shrink)

Construction cost estimation is one of the essential processes in construction management. Project cost is a complex engineering problem due to various factors affecting the construction industry. Accurate cost estimation is important in construction management and significantly impacts project performance. Artificial intelligence models have been effectively implemented in construction management studies in recent years owing to their capability to deal with complex problems. In this research, extreme gradient boosting is developed as an advanced input selector algorithm and coupled with three (...) AI models, including random forest, artificial neural network, and support vector machine for cost estimation. Datasets were gathered based on a survey conducted on 90 building projects in Iraq. Statistical indicators and graphical methods were used to evaluate the developed models. Several input predictors were used, and XGBoost highlighted inflation as the most crucial parameter. The results indicated that the best prediction was attained by XGBoost-RF using six input parameters, with r-squared and the mean absolute percentage error equal to 0.87 and 0.25, respectively. The comparison results revealed that all AI models showed good prediction performance when applied to datasets affected by more than two parameters. The outcomes of this research revealed an optimistic strategy that can help decision makers select the influencing parameters in the early phases of project management. Also, developing a prediction model with high precision results can assist the project’s estimators in decreasing the errors in the cost estimation process. (shrink)

Nowadays, higher education worldwide is affected by the COVID-19 pandemic. It has affected students’ attendance in the universities and causes universities to close down in more than 190 countries. On the other hand, novice engineers studied only a few lectures related to highway engineering. Their lectures have included very little knowledge about asphalt pavement construction as highway engineering consists of many areas that are not studied in detail during their studying years subject to their traditional education. Due to all mentioned, (...) a new drive to promote online learning paves the way to evaluate our future approach to curriculum development and delivery of educational materials for engineering courses. However, experts can offer solutions to these problems using their past experience. Hence, a system that allows experts to share their experience with other engineers after completing a project is needed. Nevertheless, the web-based expert system for maintaining flexible pavement problems in tropical regions designed in this study is a novel concept. Prior to developing this system, the need for such a system was determined through literature review and validated through a questionnaire survey. Experts were interviewed, and a questionnaire survey was conducted to construct the knowledge base of the system. Knowledge was presented as rules and coded in software through PHP programming. Web pages that support the user interface were designed using a framework that consists of CSS, HTML, and J-Query. Furthermore, the system was tested by an array of users engaged in highway engineering, namely, experts, teaching experts, novice engineers, and students. The mean values of the overall system evaluation performed by 20 users using a five-point Likert scale were 4, 4.5, 3.75, 4.25, 5, 4, and 3.5. Expert and user satisfaction prove the effectiveness of the proposed system. (shrink)

William Lane Craig has recently formulated a set of arguments that aim to undermine the rationality of Islamic theism. This paper will consider seven arguments that Craig deploys against Muslim belief. The seven arguments can be summarised as follows: (1) the Quran makes an egregious historical error by denying the crucifixion of Jesus; (2) the Quran contains legendary stories about Jesus; (3) the Quran is mistaken about the self-understanding of Jesus; (4) the Quran misunderstands the Trinity; (5) the Islamic concept (...) of God is morally deficient; (6) the Islamic concept of God is less plausible than a Trinitarian concept of God; and (7) the Muslim doctrine of salvation compromises God’s holiness and proves to be unattainable. I contend that Craig’s arguments, when examined closely, do not undermine the rationality of Islamic theism. (shrink)

: The "major Islamic philosophers," writes Deborah Black, "produced no works dedicated to aesthetics, although their writings do address issues that contemporary philosophers might study under that heading." The emergent theme in this essay is that classical Islamic philosophy may be studied within a framework of aesthetics. To achieve this goal, the metaphysics of Abu Hamid al-Ghazālī (1058–1111) and the aesthetics of Arthur Schopenhauer (1788–1860) will be brought together.

Most modern literature on the rationality of religious belief is primarily written from Christian and Secular perspectives, the introduction of a reflective Muslim perspective provides a fresh and alternative perspective. This work aims to pioneer an engagement with contemporary philosophical scholarship from the perspective of a reflective Muslim.

San Francisco: Harper San Francisco, 2003. Pp. 224. Paper $9.71."Islam," writes Seyyed Hossein Nasr, "is like a vast tapestry," and in his book Islam: Religion, History, and Civilization he aims to survey the masterpiece that is Islam. The present work is part of a trilogy including Ideal and Realities of Islam and The Heart (...) of Islam. Nasr states that the common theme in the trilogy "is the universalist perspective and respect for other religions" (p. xxiv). In addition, Nasr clarifies that his approach, as with all of his Islamic writings, is to write from an Islamic perspective, which he terms "traditional Islam" (p. xxiii). Nasr stands opposed to either the secular modernist or fundamentalist perspectives, both of which he regards as forms of extremism.This book, initially published as part of Our Religions, edited by A. Sharma, is significantly revised and includes a new introduction and bibliography. It can best be described as a primer on Islam, consisting of eight chapters that focus on a variety of pertinent themes.Chapter 1 deals with the self-understanding of Islam and the Islamic world. Islam, Nasr notes, sees itself as a return to the primordial faith of humanity, a faith that affirms the unity and oneness of God. This chapter also presents an overview [End Page 495] of the various ethnic and cultural groupings within the Muslim world, and charts the spread and demographic growth of Islam.Chapter 2 introduces the notion of al-din, an Arabic term that corresponds closely to the word "religion." Nasr contrasts the two words, where religion means "to bind" while al-din means "debt" (p. 25). Thus, religion, as framed by Islam, involves the notion of debt, in particular humanity's debt to the Divine. The chapter also discusses the significance of the Qur'an and Muhammad as the messenger of God.Chapter 3 begins with an exposition of the nature of Divinity, which is at the heart of Islamic doctrine. As Nasr explains, the Divine is understood as being "at once the Absolute, the Infinite, and the Perfect Good" (p. 59). The remainder of the chapter deals with various Islamic doctrines and beliefs, including prophecy and revelation, human nature, the Qura'nic view of men and women, and eschatology.Chapter 4 deals with the content, codification, and schools of Shariah, the Divine Law of Islam. There is also an interesting discussion of Sufism, which Nasr claims "is like the heart of the body of Islam" (p. 81). Controversially, Nasr claims that "the spread of Islam outside of the Arab and Persian worlds up to the present day has been mostly through Sufism" (p. 87).Chapter 5 delves into the central pillars of Islam, which accompany the belief in God and in Muhammad as the messenger of God. The pillars are salah (canonical prayer), sawn (fasting), hajj (pilgrimage), and zakah (religious tax or charity). Associated with these pillars is the notion of jihad, and here Nasr writes, "jihad... is usually mistranslated into English as 'holy war,' but literally means 'exertion' or 'effort' in the path of God" (p. 91). Also covered are the topics of family, ethics, and economic and political institutions.Chapter 6 presents the historical evolution of Islam beginning with the migration of Muhammad to Medina, and the events leading to the divide between Sunnis and Shiites.Chapter 7 discusses the early Islamic community, who found themselves in the "throes of disputes over such issues as whether human beings are saved by faith or works, whether there is freewill or determinism, and questions concerning the sacred text as the Word of God" (p. 154). Nasr then explores the various schools of theology and philosophy that arose in order to address these questions of faith.Chapter 8, the final chapter of the book, attempts to evaluate the place of Islam in the contemporary world. Nasr concludes by noting that despite the challenges of secular modernism and fundamentalism the vast majority of Muslims remain committed to the truth of Islam, and bear witness to the Oneness of God and the Oneness of humanity.The one quibble...
