Book Description
Complex three dimensional flow fields are seen to consist of identifiable, morphologically invariant, mildly interacting, flow structures or modules. Outputs of such flow fields such as wind loads, heat and mass transfer, flow quality, mixing, and pressure losses can be rationally established and with a knowledge of the modular structure. The paper discusses the modular approach for the case of flows around three-dimensional obstacles in boundary layers and for the case of tailoring free-stream flow and turbulence by flow inserts such as screens, perforated plates, honeycombs and foam slabs. (Author Modified Abstract).

Book Description
These two volumes contain the proceedings of the workshop on the Institute for Computer Instability and Transition, sponsored by Applications in Science and Engineering (ICASE) and the Langley Research Center (LaRC), during May 15 to June 9, 1989. The work shop coincided with the initiation of a new, focused research pro gram on instability and transition at LaRC. The objectives of the workshop were to (i) expose the academic community to current technologically important issues of instability and transition in shear flows over the entire speed range, (ii) acquaint the academic com munity with the unique combination of theoretical, computational and experimental capabilities at LaRC and foster interaction with these facilities, (iii) review current state-of-the-art and propose fu ture directions for instability and transition research, (iv) accelerate progress in elucidating basic understanding of transition phenomena and in transferring this knowledge into improved design methodolo gies through improved transition modeling, and (v) establish mech anisms for continued interaction. The objectives (i) to (iii) were of course immediately met. It is still premature to assess whether ob jectives (iv) and (v) are achieved. The workshop program consisted of tutorials, research presenta tions, panel discussions, experimental and computational demonstra tions, and collaborative projects.

Book Description
Using Toyota's principles for product and process development, this book focuses the implementation of the Lean system during the past 10 years in dozens of corporations across various industries. The book highlights all steps on the journey from common trouble area to remarkable results. As it is written by a manager for other managers, it contains real work discoveries and insights. The author provides case studies from many different fields of application. The reader gains insight on US and European companies that successfully streamlined their innovation and product-development processes. These companies have overcome difficult periods and major challenges thanks to the ability to innovate with new Lean methodologies and, above all, a new workplace culture and mindset. The goal of this book is to help managers successfully apply Lean principles in the innovation and development area of their company while benefitting from the author's lessons learned during his many years of capitalized experience. This book provides a comprehensive framework that supports, step-by-step, the successful application of Lean principles in the innovation and development areas of the company. Readers learn how to drastically reduce the time required to develop products and discover and eliminate hidden costs and critical waste while increasing value for customers.

Book Description
These Proceedings contain the papers and oral discussions presented at the Symposium on AERODYNAMIC DRAG MECHANISMS of Bluff Bodies and Road Vehides held at the General Motors Research Laboratories in Warren, Michigan, on September 27 and 28, 1976. This international, invitational Symposium was the twentieth in an annual series, each one having been in a different technical discipline. The Symposia provide a forum for areas of science and technology that are of timely interest to the Research Laboratories as weIl as the technical community at large, and in which personnel of the Laboratories are actively involved. The Symposia furnish an opportunity for the exchange of ideas and current knowledge between participating research specialists from educational, industrial arid governmental institutions and serve to stimulate future research activity. The present world-wide energy situation makes it highly desirable to reduce the force required to move road vehicles through the atmosphere. A significant amount of the total energy consumed for transportation is expended in overcoming the aerodynamic resistance to motion of these vehicles. Reductions in this aerodynamic drag can therefore have a large impact on ground transportation energy requirements. Although aerodynamic development work on road vehides has been performed for many years, it has not been widely reported or accompanied by much basic research.

Book Description
Gets professionals quickly on-line with all the crucial designconcepts and skills they need to dramatically improve themaintainability of their products or systems Maintainability is a practical, step-by-step guide to implementinga comprehensive maintainability program within your organization'sdesign and development function. From program scheduling,organizational interfacing, cost estimating, and supplieractivities, to maintainability prediction, task analysis, formaldesign review, and maintainability tests and demonstrations, itdescribes all the planning and organizational aspects ofmaintainability for projects under development and * Schools readers in state-of-the-art maintainability designtechniques * Demonstrates methods for quantitatively measuring maintainabilityat every stage of the development process * Shows how to increase effectiveness while reducing life-cyclecosts of already existing systems or products * Features numerous case studies, sample applications, and practiceexercises * Functions equally well as a professional reference and aclassroom text Independent cost analysis studies indicate that an inordinatelylarge percentage of the overall life-cycle cost of mostsystems/products is currently taken up by maintenance and support.In fact, for many large-scale systems, maintenance and support havebeen shown to account for as much as 60% to 75% of overalllife-cycle costs. At a time of fierce global competition, long-termcost effectiveness is a major competitive advantage thatmanufacturers simply cannot afford to underestimate. Clearly then,to remain competitive in today's international marketplace,companies must institute programs for reducing system maintenanceand support costs-- comprehensive programs that are an integralpart of the design and development process from its earliestconceptual stages. This book shows you how to implement such a program within yourorganization's design and development function. From programscheduling, organizational interfacing, cost estimating, andsupplier activities, to maintainability prediction, task analysis,formal design review, and maintainability tests and demonstrations,it describes all the planning and organizational aspects ofmaintainability for projects under development while schooling youin the use of the full range of proven design techniques--includingmethods for quantitatively measuring maintainability at every stageof the development process. The authors also clearly explain howthe principles and practices outlined in Maintainability can beapplied to the evaluation of systems/products now in use both toincrease their effectiveness and reduce long-term costs. While theoretical aspects of maintainability are discussed, theauthors' main purpose in writing this book is to help getprofessionals quickly on-line with the essential maintainabilityconcepts and skills. Hence, in addition to clarity of presentationand a rational hierarchical format, Maintainability features manycase studies and sample applications that help to clarify thepoints covered, and numerous practice exercises that help engineersto test their mastery of the concepts and techniques covered. Maintainability is an invaluable professional tool for engineersfrom all disciplines who are involved with the design, testing,prototyping, manufacturing, and maintenance of products andsystems. It also serves as a superior course book forgraduate-level programs in those disciplines.
