Velocity


Book Description

Millions of readers remember The Goal, the landmark business novel that sets forth by way of story the essential principles of Eliyahu Goldratt's innovative methods of production. Now, from the AGI-Goldratt Institute and Jeff Cox, the same creative writer who co-authored The Goal, comes VELOCITY, the book that reveals how to achieve outstanding bottom-line results by integrating the world's three most powerful continuous improvement disciplines: Lean, Six Sigma, and Goldratt's Theory of Constraints. Used by the United States Navy and United States Marine Corps to dramatically improve some of the most complex, logistically vast supply chains in the world, the VELOCITY APPROACH draws on the strengths of all three disciplines to deliver breakthrough performance gains. In physics, speed with direction is velocity; in business, the application of VELOCITY means your organization can achieve operational speed with strategic direction to outmaneuver competitors, gain loyalty with customers, and rapidly build sustainable earnings growth -- in as little as one or two business quarters. Dee Jacob and Suzan Bergland, two princi-pals of AGI, have been teaching the concepts, techniques, and tools of VELOCITY to major corporations, including Procter & Gamble, ITT, and Northrop Grumman, for years. Now they unlock the door for you to see how to apply their insights and methods to your organization -- be it business, not-for-profit, manufacturing, or service based -- in order to shorten lead times, slash inventories, reduce production variability, and increase sales. Writer Jeff Cox returns with the vivid, realistic style that made The Goal so readable yet so edifying. Thrust into the presidency of the subsidiary company where she has managed sales and marketing, Amy Cieolara is mandated by her corporate superiors to implement Lean Six Sigma (LSS) in order to appease a key customer. Assigned to help her is LSS Master Black Belt Wayne Reese, installed as her operations manager. But as time goes on and corporate pressure mounts, Amy finds she has to start thinking for herself -- and learning from everyone around her -- and she arrives at the series of steps that form the core of the VELOCITY APPROACH. VELOCITY offers keen insight into the human and organizational factors that so often derail growth while teaching you proven, practical techniques for restarting and revving up the internal engines of your company to reach new levels of success. Colorful characters, believable situations, and everything from dice games to AGI's "reality tree" techniques make this business novel a vital resource for everyone seeking to deliver business improvement in these challenging economic times -- and far into the future.




Mass Addition in the Stagnation Region for Velocity Up to 50,000 Feet Per Second


Book Description

Solutions of the viscous shock layer equations with mass addition are obtained. Flow-field equations include the effects of heat conduction, diffusion of reacting species, and emission and absorption of gaseous radiation for dissociated and partially ionized air in chemical equilibrium. Convective and radiative heating rates with mass addition are obtained from the solutions. Algebraic equations are derived for predicting the nose radius that minimizes total heating rates at a given flight speed and shock-layer pressure level. Values for the corresponding natural ablation rate, the effective heat of ablation, the ratio of radiative to convective heating rate, surface shear stress, and shock-wave standoff distance are given. The effects of ablated gases that radiate more strongly than air are examined. Solutions without mass addition at low Reynolds numbers where external vorticity, energy depletion, and flow energy limiting are important are compared with existing theory and experiments.




A Method for the Instantaneous Determination of the Velocity and Direction of the Wind


Book Description

The laboratory instruments, which we often constructed with makeshift means, gave encouraging results and showed that they could satisfactorily meet the required conditions. By limiting ourselves to the employment of hot wires of 0.05 mm (0.002 in.) diameter, we obtained instruments which faithfully followed all the wind fluctuations of over 0.1 second and even much more rapid variations without any very great error.
