This paper adopts two modeling tools, namely, multiple linear regression (MLR) and artificial neural networks (ANNs), to predict the concentrations of heavy metals (zinc, boron, and manganese) in surface waters of the Oued Inaouen watershed flowing towards Inaouen, using a set of physical-chemical parameters. XLStat was employed to perform multiple linear and nonlinear regressions, and Statista 10 was chosen to construct neural networks for modeling and prediction. The effectiveness of the ANN- and MLR-based stochastic models was assessed by the determination (...) coefficient (R²), the sum squared error (SSE) and a review of fit graphs. The results demonstrate the value of ANNs for prediction modeling. Drawing on supervised learning and back propagation, the ANN-based prediction models adopt an architecture of [18-15-1] for zinc, [18-11-1] for manganese, and [18-8-1] for boron, and perform effectively with a single cached layer. It was found that the MLR-based prediction models are substantially less accurate than those based on the ANNs. In addition, the physical-chemical parameters being investigated are nonlinearly correlated with the levels of heavy metals in the surface waters of the Oued Inaouen watershed flowing towards Inaouen.

This book has been written as a basic introduction to the Muslim Philosophy. It comprises of some fundamental philosophical problems on which Muslim Philosophy is based upon. Muslim Philosophy is the philosophical study of interpretations and knowledge derived from the Quran, the Hadiths and other significant sources of teachings of Islam. Among these, Quran is the divine source of philosophy which explains the different aspects of world and guides to the true knowledge. Muslim Philosophy is the philosophy which discusses the (...) fundamental problems of the world like existence, universals, mind, thought, language, God, world, soul, reality, knowledge and values. However, these problems or questions demand answers from the philosophers’ attitudes and points of view which are highlighted in this book at a beginner’s level. It is also a matter of fact that these problems or issues could not be answered through other ways. The need of the hour is that the philosophical ways, Islamic principles and methods distinguish these matters of facts from other disciplines. So, this book is helpful for undergraduate, postgraduate, and multidisciplinary scholars and thinkers interested in studying the basics of the Muslim Philosophy. It is also a valuable source for those who are just interested in acquiring knowledge in the field of Muslim Philosophy. This work shall guide them to understand the basic principles of Islamic Philosophy. The most notable Muslim Philosophers who are mentioned in this book are: Al-Kindi, Al-Gazali, Ibn Rushd, Al-Farabi, Sheikh Ahmad Sirhindi, Ibn-Arabi, Sheikh Nurrudin Wali (Nund-Reshi), Ibn Tayamiyya, Ibn-Sina, Shah Waliullah, Hamza Makhdhoomi, Allama Iqbal and Lal Ded. Furthermore, a few other important concepts of philosophy that have been mentioned in this book are Mutazalism, Asharism, Sufism and Articles of Faith. (shrink)
