This book studies selected advanced flight control schemes for an uncertain quadrotor unmanned aerial vehicle (UAV) systems in the presence of constant external disturbances, parametric uncertainties, measurement noise, time-varying external disturbances, and random external disturbances. Furthermore, in all the control techniques proposed in this book, it includes the simulation results with comparison to other nonlinear control schemes recently developed for the tracking control of a quadrotor UAV. The main contributions of the present book for quadrotor UAV systems are as follows:(i)the proposed control methods are based on the high-order sliding mode controller (SMC) and hybrid control algorithm with an optimization method.(ii)the finite-time control schemes are developed by using fast terminal SMC (FTSMC), nonsingular FTSMC (NFTSMC), global time-varying SMC, and adaptive laws. (iii) thefractional-order flight control schemes are developed by using the fractional-order calculus theory, super twisting algorithm, NFTSMC, and the SMC.This book covers the research history and importance of quadrotor system subject to system uncertainties, external wind disturbances, and noise measurements, as well as the research status of advanced flight control methods, adaptive flight control methods, and flight control based on fractional-order theory. The book would be interesting to most academic undergraduate, postgraduates, researchers on flight control for drones and applications of advanced controllers in engineering field. This book presents a must-survey for advanced finite-time control for quadrotor system. Some parts of this book have the potential of becoming the courses for the modelling and control of autonomous flying machines. Readers (academic researcher, undergraduate student, postgraduate student, MBA/executive, and education practitioner)interested in nonlinear control methods find this book an investigation. This book can be used as a good reference for the academic research on the control theory, drones, terminal sliding mode control, and related to this or used in Ph.D. study of control theory and their application in field engineering.

This book consists of two parts. The first part studies selected recent developed strategies of control and management for renewable energy resources. The strategies of control are tested in the presence of unbalance power, voltage faults, frequency deviation, wind speed variation and parametric uncertainties.  The second part is especially focused on study of hybrid photovoltaic (PV)-Concentrated solar power (CSP) coupled to a thermal storage system. It gathers a set of chapters covering recent survey literature, modelling and optimization of hybrid PV-CSP power plants. In this part, a detailed model of hybrid PV-CSP with thermal storage system is presented and smart optimization techniques like particle swarm optimization (PSO) and genetic algorithm (GA) are also described and used to optimally design the hybrid PV-CSP renewable energy system. The book would be interesting to most academic undergraduate, postgraduates, researchers on renewable energy systems in terms of modeling, optimization and control, as well as the satisfaction of grid code requirements. Also, it provides an excellent background to renewable energy sources, it is an excellent choice for energy engineers, researchers, system operators, and graduate students. This book can used as a good reference for the academic research on the smart grid, power control, integration of renewable energy sources, and related to this or used in Ph.D study of control, optimisation, management problems and their application in field engineering.

Essay on Islamization is a study of the Islamization of all Muslim societies, their conversion to orthodox Islam which, with its chapels, soldier monks and holy war, leads to fundamentalism as well as to a moral puritanism. Cherkaoui gauges the importance of this global phenomenon by analyzing the empirical data of some sixty Muslim and non-Muslim societies. He also conducts two ethnographic surveys to identify the metamorphoses of Muslim religious practices and their causes. Among the dozen theories put forward to explain these planetary phenomena, he cites those of secularization, modernization, the religious market, the influence of the media and the policy of donors of unlimited financial resources, social mobility, geopolitical causes, the emergence of fundamentalism and the role of "proletarian" intellectuals who promote Messianism, and social pressure.

Of Tribes and Empires challenges the idea that states and empires naturally emerge by overcoming tribal societies. Focusing on the region from the Sahara to the Gobi Desert, Cherkaoui argues that political order has long been shaped by a durable struggle between tribal organization and imperial power. Empires rise by incorporating tribes, yet rarely succeed in neutralizing them. From the incomplete Romanization of Berber societies to the institutional fragility of Islamic empires, tribal structures repeatedly undermine imperial centralization. This unresolved tension, Cherkaoui contends, continues to shape political authority in contemporary Arab-Muslim societies and helps explain the failure of the emergence of capitalism and liberal-democracy. The book also reveals why imperial claims to cultural universality collapse, introducing “proletaroid intellectuals” as key producers of ideological resistance and alternative forms of legitimacy.
