This book reviews emerging nanomaterials in catalysis and sensors. The catalysis section covers the role of nano-photocatalysts in organic synthesis and health care application, oxidation and sulphoxidation reactions, liquid phase oxidation, hydrogen evolution and environmental remediation. It highlights the correlation of surface properties and catalytic activity of the mesoporous materials. The sensor section discusses the fabrication and development of various electrochemical, chemical, and biosensors. Nanostructured materials have attracted intensive scientific attention because, at the nanoscale level, unique electrical, magnetic, optical and mechanical properties emerge. The size- dependent properties of nanostructured materials provide the highest potentials for increasing performance and extending their applications in many diverse fields, such as sensors, display technology, energy storage and energy conversion process, catalysis, pharmaceutical and biomedical. Sensors are devices that are frequently used to detect a variable quantity, commonly electronically, and sensors convert the measurement into specific signals.

The focus of this book is kinematic and dynamic control of a single mobile robot or a group of them. New simple and integrated solutions are presented for tasks of positioning, trajectory tracking and path following. Control of Ground and Aerial Robots synthesizes new results on control of mobile robots developed by M.Sc. and Ph.D. students supervised by the authors. The robots considered are wheeled mobile platforms, with emphasis on differential drive vehicles, and the multirotor aerial robots. Integrated control solutions based on the technique of feedback linearization are proposed to guide either a single robot or a homogeneous/heterogeneous group of mobile robots. Examples on the use of the proposed controllers are also provided. Finally, Control of Ground and Aerial Robots is intended to help graduate and advanced undergraduate students in engineering, as well as researchers in the area of robot control, to design controllers to autonomously guide the more common mobile platforms.

Монография посвящена выделению из шума потока сигналов. Сигналы и шум принимаются в единой смеси. Число и параметры сигналов неизвестны, но подчиняются известным при приеме статистическим закономерностям. В качестве математического аппарата используются теория случайных потоков, апостериорный статистический анализ и теория статистических решений. Изучаются схемы для обнаружения и измерения параметров сигналов в условиях коррелированных в общем случае потоков неразличимых, классифицированных, группированных, движущихся, размножающихся и взаимопревращающихся сигналов...

Dimensions of Uncertainty in Communication Engineering is a comprehensive and self-contained introduction to the problems of nonaleatory uncertainty and the mathematical tools needed to solve them. The book gathers together tools derived from statistics, information theory, moment theory, interval analysis and probability boxes, dependence bounds, nonadditive measures, and Dempster–Shafer theory. While the book is mainly devoted to communication engineering, the techniques described are also of interest to other application areas, and commonalities to these are often alluded to through a number of references to books and research papers. This is an ideal supplementary book for courses in wireless communications, providing techniques for addressing epistemic uncertainty, as well as an important resource for researchers and industry engineers. Students and researchers in other fields such as statistics, financial mathematics, and transport theory will gain an overview and understanding on these methods relevant to their field.

This text discusses sensitivity parametric analysis for the single tuned filter parameters and presents an optimization-based method for solving the allocation problem of the distributed generation units and capacitor banks in distribution systems. It also highlights the importance of Artificial Intelligence (AI) techniques such as water cycle algorithms in solving power quality problems such as over-voltage and harmonic distortion. This book proposes two procedures for improving the power quality (PQ) of the distribution systems. The considered PQ parameters are voltage profile, voltage deviation, voltage stability index and harmonic distortion in smart distribution systems. One of the most important features of smart distribution systems is the presence of distributed generation units (DGs). Therefore, the positive and negative effects of the DGs on distribution system PQ are studied. The first proposed procedure is concerned with determining the optimal placement and sizing of DGs and CBs in distribution system for improving the system PQ besides other technical, economic, and environmental benefits. Also, this book proposes single-tuned filters (STFs) as an effective tool for mitigating the harmonic distortion in distribution systems. A parametric analysis is presented for determining the effect of different filter parameters on its performance, which helps system designers obtain the optimal filter design that can mitigate specific harmonic orders.

This textbook will continue to be the best suitable textbook written specifically for a first course on probability theory and designed for industrial engineering and operations management students. The book offers theory in an accessible manner and includes numerous practical examples based on engineering applications. Probability Foundations for Engineers, Second Edition continues to focus specifically on probability rather than probability and statistics. It offers a conversational presentation rather than a theorem or proof and includes examples based on engineering applications as it highlights Excel computations. This new edition presents a review of set theory and updates all descriptions, such as events versus outcomes, so that they are more understandable. Additional new material includes distributions such as beta and lognormal, a section on counting principles for defining probabilities, a section on mixture distributions and a pair of distribution summary tables.

The use of Robotic Process Automation (RPA) can release considerable efficiency potential for organizations and thus create new opportunities for employees without having to set up costly (IT) projects. The increasing response from practitioners and the high growth expectations for the RPA market in the coming years are therefore not surprising. However, the necessary prerequisites, functionalities and steps for the introduction of this new technology are more extensive than one might initially suspect. Freely available literature and documentation on this are unfortunately usually superficial, not very objective or incomplete. For this reason, we decided to systematize our many years of experience with the use of RPA software and to document it in an easily understandable and practical manner. The new or further development of numerous digitization technologies in recent years has contributed to the evolution of RPA into so-called Intelligent Process Automation (IPA). IPA combines RPA with other digitization technologies in order to give classic software robots more advanced (cognitive) capabilities.
