state of the art in aeronautical engineering has been continually accelerated by the development of advanced analysis and design tools. Used in the early design stages for aircraft and spacecraft, these methods have provided a fundamental understanding of physical phenomena and enabled designers to predict and analyze critical characteristics of new vehicles, including the capability to control or modify unsatisfactory behavior. For example, the relatively recent emergence and routine use of extremely power- ful digital computer hardware and software has had a major impact on design capabilities and procedures. Sophisticated new airflow measurement and visualization systems permit the analyst to conduct micro- and macro-studies of properties within flow fields on and off the surfaces of models in advanced wind tunnels. Trade studies of the most efficient geometrical shapes for aircraft can be conducted with blazing speed within a broad scope of integrated technical disciplines, and the use of sophisticated piloted simulators in the vehicle development process permits the most important segment of operations—the human pilot—to make early assessments of the acceptability of the vehicle for its intended mission. Knowledgeable applica- tions of these tools of the trade dramatically reduce risk and redesign, and increase the marketability and safety of new aerospace vehicles.

Modeling Applications in the Airline Industry explains the different functions and tactics performed by airlines during their planning and operation phases. Each function receives a full explanation of the challenges it brings and a solution methodology is presented, supported by numerical illustrative examples wherever possible. The book also highlights the main limitations of current practice and provides a brief description of future work related to each function. The authors have filtered the rich literature of airline management to include only the research that has actually been adopted by the airlines, giving a genuinely accurate representation of real airline management and its continuing development of solution methodologies. The book consists of 20 chapters divided into 4 sections: - Demand Modeling and Forecasting - Scheduling of Resources - Revenue Management - Irregular Operations Management. The book will be a valuable source or a handbook for individuals seeking a career in airline management. Written by experts with significant working experience within the industry, it offers readers insights to the real practice of operations modelling. In particular the book makes accessible the complexities of the key airline functions and explains the interrelation between them.

Indoor flight with light models offers fascinating possibilities thanks to new micro-components and construction methods. The variety of materials (balsa, polystyrene, boron fibres, Mylar film, etc.) makes possible not only classic indoor flight with rubber propulsion but also electric indoor flight with new components (coreless motors, micro-RC equipment, tiny lithium polymer cells). A section is also devoted specifically to supercapacitor propulsion. The most important feature of all light models with weights of typically 1.5 to 10 grams is the slow flying at walking pace. The risk of damage is correspondingly low. Another advantage of indoor flying is that it can be practised all year round, regardless of the weather. The door is wide open for school projects. The author has held numerous workshops in schools and at the Deutsches Museum, as well as supervising teachers in Saalflug projects. He has also been a participant in numerous international and national competitions. The book helps to overcome the initial threshold of lightweight construction with detailed instructions and construction plans. It accompanies the model flyer, starting with simple models suitable for the beginner or for workshop instruction, up to competition performance models. Let yourself "decelerate" and enjoy the slowly floating flying objects! From the content: • History of Indoor flight • Model classes • Materials • Working techniques • Rubber propulsion • Electric propulsion • CO2 drive • Supercapacitors • Balloon launch • Air wave • Flight practice • Propeller • Entry-level models • Styrofoam models • Construction plans

Driven by demand from the entertainment industry for better and more realistic animation, technology continues to evolve and improve. The algorithms and techniques behind this technology are the foundation of this comprehensive book, which is written to teach you the fundamentals of animation programming. In this third edition, the most current techniques are covered along with the theory and high-level computation that have earned the book a reputation as the best technically-oriented animation resource. Key topics such as fluids, hair, and crowd animation have been expanded, and extensive new coverage of clothes and cloth has been added. New material on simulation provides a more diverse look at this important area and more example animations and chapter projects and exercises are included. Additionally, spline coverage has been expanded and new video compression and formats (e.g., iTunes) are covered. Includes companion site with contemporary animation examples drawn from research and entertainment, sample animations, and example code Describes the key mathematical and algorithmic foundations of animation that provide you with a deep understanding and control of technique Expanded and new coverage of key topics including: fluids and clouds, cloth and clothes, hair, and crowd animation Explains the algorithms used for path following, hierarchical kinematic modelling, rigid body dynamics, flocking behaviour, particle systems, collision detection, and more

Modelling and Managing Airport Performance provides anintegrated view of state-of-the-art research on measuring andimproving the performance of airport systems with consideration ofboth airside and landside operations. The considered facets ofperformance include capacity, delays, economic costs, noise,emissions and safety. Several of the contributions also examinepolicies for managing congestion and allocating sparse capacity, aswell as for mitigating the externalities of noise, emissions, andsafety/risk. Key features: Provides a global perspective with contributing authors fromEurope, North and South America with backgrounds in academia,research institutions, government, and industry Contributes to the definition, interpretation, and sharedunderstanding of airport performance measures and relatedconcepts Considers a broad range of measures that quantify operationaland environmental performance, as well as safety and risk Discusses concepts and strategies for dealing with themanagement of airport performance Presents state-of-the-art modelling capabilities and identifiesfuture modelling needs Themed around 3 sections – Modelling Airport Performance,Assessing Airport Impacts, and Managing Airport Performance andCongestion Modelling and Managing Airport Performance is avaluable reference for researchers and practitioners in the globalair transportation community.
