Paperback. Condizione: new. Paperback. This brief explores the pivotal realm of droplet cavitation, a subject of great significance for enhancing fuel atomization and improving various industrial processes. The authors employ high-speed photography experiments, analyze bubble dynamics equations, and utilize numerical simulations to explore the dynamic behavior of cavitation bubbles and droplets. The book analyzes the entire lifecycle of cavitation bubbles, their interactions with different liquid droplets, and the key parameters governing their oscillation and collapse and sheds light on the collapse mechanisms and shock wave propagation influenced by liquid droplets. Additionally, it investigates the dynamics of droplet spattering by categorizing spatter patterns under diverse conditions, discusses the critical stability of droplet surfaces, and reveals the mechanisms by which cavitation bubble collapses induce droplet breakage. Taking vapor bubbles and diesel droplets as examples, the dynamic characteristics of specific droplets containing bubbles are also analyzed. This book offers an in-depth understanding of these phenomena with practical implications for a wide range of industrial applications and is a useful tool for researchers and engineers working in the fields of fluid dynamics, combustion engineering, and atomization processes. Additionally, it investigates the dynamics of droplet spattering by categorizing spatter patterns under diverse conditions, discusses the critical stability of droplet surfaces, and reveals the mechanisms by which cavitation bubble collapses induce droplet breakage.

Paperback. Condizione: new. Paperback. This book focuses on developing and optimizing ceramic membranes with hydrophobic and superhydrophobic properties for CO2 capture in membrane contactors, aimed at improving CO2 capture technology in thermal power plants and other industries. It examines the preparation of ceramic membranes, the mass transfer mechanisms in porous media, and the specific processes involved in capturing CO2. The book also compares the performance of commercial Al2O3 ceramic membranes with traditional polytetrafluoroethylene membranes and explores ways to enhance the efficiency of CO2 capture by addressing challenges such as membrane wetting and increased mass transfer resistance. Additionally, it introduces a cost-effective superhydrophobic ceramic membrane made from power plant waste fly ash, analyzing its performance and surface dynamics for CO2 capture applications. It is a useful tool for researchers, academics, professionals and graduates interested in the field of chemical engineering, environmental science, and materials science, particularly those focused on CO2 capture technologies, membrane science, and clean energy solutions.

Published without a dust jacket. -- E-commerce has passed through a number of stages in the minds of most readers of the daily press. Initially it was the province of the specialist and considered almost irrelevant to the needs and activities of everyday life - companies looking for venture capital in this area had little if any chance of obtaining sufficient funds from the rather conservative investors who provided the only source of start-up capital. Then came the dotcom boom - and suddenly e-commerce was the most exciting topic possible! Venture capital was available from every possible source and almost any company with a .com in its name could be assured of instant funding on request. This boom was, inevitably, followed by the dotcom bust and the press warned that the days of e-commerce were gone, perhaps never to return. This apparently confusing 'stages of growth' model is in reality nothing of the sort. E-commerce is simply the logical outcome of combining computers with telecommunications networks. The astonishing changes which a global economy has brought with it are reflected in the changes to the way we do business which are increasingly synonymous with e-commerce. Indeed, the term e-commerce itself is coming to mean only the transaction-based component of e-business - 'any process that a business organisation conducts over a computer-mediated network' as Thomas Mesenbourg of the U.S. Census Bureau said in 1999. -- Contents: Part 1 Fundamentals: -- Case-based Reasoning [Knowledge & Experience; From Expert Systems to CBR Systems; Process Models of Case Based Reasoning; Case-based Reasoning: A Process Reasoning; Case Representation; Case Indexing & Case Retrieval; Case Adaptation & Case Evaluation; Experience-Based Reasoning]; E-Commerce [Traditional Commerce vs E-Commerce; E-Market & its Characteristics; Three Chains for E-Commerce; Transaction-based E-Commerce; Information Overload & Search; Information Brokerage]; Intelligent Agents and Multiagent Systems [Intelligent Agents; Mobile Agents; Intelligent Brokers; Multiagent Systems; ES = MAS?; Architecture of Multiagent Systems]; A General Theory of Case Based Reasoning [Similarity & Metrics in Case-based Reasoning; Case Base Building with Similarity Relations; R5 Model for Case-based Reasoning; Abductive Case-based Reasoning; Rule-based Models for Case Retrieval; Fuzzy Rule-based Case Retrieval]; Part 2 Interrelations: -- CBR in E-Commerce [General Architecture of Web-Based CBR Systems; Unified Logical Model of CBR-Based E-Commerce Systems; Intelligent Sales Support with CBR; Product Recommendation; Product Configuration with CBR; Negotiation Using CBR]; Case Based Reasoning in Multiagent Systems [Knowledge-based Model of Multiagent CBR Systems; Distributed Case Base & Retrieval; CBR for Agent Team Coordination; Case-based BDI Agents; Cooperative CBR Agents in MAS; Applying CBR to Multiagent Negotiation]; Multiagent E-Commerce [Agent-based E-commerce; Multiagent Negotiation; Auction-based E-Commerce; Mediation-based E-Commerce; Brokerage-based E-Commerce; Architecture of Multiagent Brokerage]; Part 3 Integration: -- Integration of CBR and MAS in E-Commerce [Parsimony of Intelligence in Multiagent Systems; CBR for Multiagent E-Commerce; CMB: Integration of CBR & Multiagent Brokerage; Analysis & Design of CMB; Implementing CMB]; Concluding Remarks [Case-based Reasoning; Knowledge Management & Experience Management; E-commerce & E-business; Web Intelligence; Artificial Intelligence; Multiagent Systems; Information Systems; Boolean Algebra; Future Work; End without End]; Bibliography.
