Formation and Control of Biofilm in Various Environments

by Hideyuki Kanematsu Dana M. Barry

This book provides excellent techniques for detecting and evaluating biofilms: sticky films on materials that are formed by bacterial activity and produce a range of industrial and medical problems such as corrosion, sanitary problems, and infections. Accordingly, it is essential to control biofilms and to establish appropriate countermeasures, from both industrial and medical viewpoints. This book offers valuable, detailed information on these countermeasures. It also discusses the fundamentals of biofilms, relates various substrates to biofilms, and presents a variety of biofilm reactors. However, the most important feature of this book (unlike others on the market) is its clear focus on addressing the practical aspects from an engineering viewpoint. Therefore, it offers an excellent practical guide for engineers and researchers in various fields, and can also be used as a great academic textbook.

Formation and Cooperative Behaviour of Protein Complexes on the Cell Membrane (Springer Theses)

by Ksenia Guseva

With the aim of providing a deeper insight into possible mechanisms of biological self-organization, this thesis presents new approaches to describe the process of self-assembly and the impact of spatial organization on the function of membrane proteins, from a statistical physics point of view. It focuses on three important scenarios: the assembly of membrane proteins, the collective response of mechanosensitive channels and the function of the twin arginine translocation (Tat) system. Using methods from equilibrium and non-equilibrium statistical mechanics, general conclusions were drawn that demonstrate the importance of the protein-protein interactions. Namely, in the first part a general aggregation dynamics model is formulated, and used to show that fragmentation crucially affects the efficiency of the self-assembly process of proteins. In the second part, by mapping the membrane-mediated forces into a simplified many-body system, the dynamic and equilibrium behaviour of interacting mechanosensitive channels is derived, showing that protein agglomeration strongly impacts its desired function. The final part develops a model that incorporates both the agglomeration and transport function of the Tat system, thereby providing a comprehensive description of this self-organizing process.

Formation and Temperature Stability of the Liquid Phase in Thin-Film Systems

by Serhii Dukarov Serhii Petrushenko Sergiy Bogatyrenko Vladimir Sukhov

This book presents a summary of the topic of supercooling during crystallization in condensed films. While recent findings are mainly published in English, the foundational classical results were originally published in Russian, with limited accessibility to general readers. The present work is based on a 2019 Ukrainian monograph, "Temperature Stability of the Supercooled Liquid Phase in Condensed Films," which has been extensively revised and expanded.The book includes a detailed analysis of the thermodynamics of supercooled fluids, with updated and expanded sections. Additionally, new results on the supercooling of indium-lead (In-Pb) alloys in contact with amorphous molybdenum and fusible metals in contact with nanocrystalline layers are presented. These layers occupy a middle ground between amorphous (carbon, molybdenum, as-deposited germanium films) and polycrystalline (copper, silver, aluminum) substrates. The book gives particular attention to the peculiarities of contracted geometry conditions, which are natural for multilayered structures and can occur through fusible component segregation at grain boundaries.The analysis of new data has prompted a rethinking of the role of the more refractory layer's microstructure on the crystallization processes of metastable melts. The book includes a thorough discussion of these findings, highlighting the crucial role of the microstructure in the crystallization process. This book is a valuable resource for researchers and students interested in crystallization in thin-film metallic systems. This comprehensive study provides a detailed and authoritative analysis of the thermodynamics of supercooled fluids, and the impact of microstructure on the crystallization processes of metastable melts, making it an essential addition to any academic library.

Formation Control: Approaches for Distributed Agents (Studies in Systems, Decision and Control #205)

by Hyo-Sung Ahn

This monograph introduces recent developments in formation control of distributed-agent systems. Eschewing the traditional concern with the dynamic characteristics of individual agents, the book proposes a treatment that studies the formation control problem in terms of interactions among agents including factors such as sensing topology, communication and actuation topologies, and computations. Keeping pace with recent technological advancements in control, communications, sensing and computation that have begun to bring the applications of distributed-systems theory out of the industrial sphere and into that of day-to-day life, this monograph provides distributed control algorithms for a group of agents that may behave together. Unlike traditional control laws that usually require measurements with respect to a global coordinate frame and communications between a centralized operation center and agents, this book provides control laws that require only relative measurements and communications between agents without interaction with a centralized operator. Since the control algorithms presented in this book do not require any global sensing and any information exchanges with a centralized operation center, they can be realized in a fully distributed way, which significantly reduces the operation and implementation costs of a group of agents. Formation Control will give both students and researchers interested in pursuing this field a good grounding on which to base their work.

This book provides a useful reference for related researchers, engineers and policy-makers engaged in atmospheric pollution research, prevention and control in China and other countries.

Formation of KNbO3 Thin Films for Self-Powered ReRAM Devices and Artificial Synapses

by Tae-Ho Lee

This thesis describes an investigation into homogeneous KN crystalline films grown on Pt/Ti/SiO2/Si substrates, amorphous KN films grown on TiN/Si substrates using the RF-sputtering method, and the ferroelectic and piezoelectric properties of these KN films. KNbO3 (KN) thin films have been extensively investigated for applications in nonlinear optical, electro-optical and piezoelectric devices. However, the electrical properties of KN films have not yet been reported, because it is difficult to grow stoichiometric KN thin films due to K2O evaporation during growth. This thesis also reports on the ReRAM properties of a biocompatible KN ReRAM memristor powered by the KN nanogenerator, and finally shows the biological synaptic properties of the KN memristor for application to the artificial synapse of a neuromorphic computing system.

Formation Tracking Control for Heterogeneous Swarm Systems

by Xiwang Dong Yongzhao Hua Zhang Ren

Swarm system, also known as multi-agent system, refers to a system composed of multiple subsystems (agents) with certain communication, calculation, decision-making, and action capabilities through local information interaction, such as a group of unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), satellites, etc. Formation tracking control of swarm systems is an important technical support and approach for the emergence of swarm intelligence at motion control level. By applying formation tracking control, swarm system agents can adjust their relations in the state or output space through neighboring information interaction, and then the swarm system can achieve favorable space-time conditions for many cooperative tasks such as source seeking, target enclosing, and surveillance. Thus, complex missions can be performed efficiently or cost-effectively. In cross-domain collaborative applications, including air-ground coordination and air-sea coordination, swarm systems are usually composed of several heterogeneous agents, and swarm intelligence can be enhanced by complementary functions of different agents. How to achieve time-varying formation tracking for heterogeneous swarm systems is crucial for cross-domain coordination, which has important theoretical value and practical significance. This important book presents a systematic theoretical approach and control framework on the time-varying formation tracking for high-order heterogeneous swarm systems. Distributed controller design and stability analysis of closed-loop systems for several specific formation tracking problems are provided. Furthermore, the proposed control approaches are applied to practical cooperative experiment platforms composed of UAVs and UGVs, and several formation tracking experiments are carried out to further verify the effectiveness of the theories.
