Experiments were conducted to determine the effects of steady-state circumferential-pressure distortion on inlet flow and internal engine performance of a high-bypass-ratio turbofan engine. To measure these effects, flow-angle, static-pressure, and total-pressure instrumentation was placed between the rotatable distortion-generator assembly and the engine inlet. In addition, both static-pressure and total-pressure were recorded at the fan exit and compressor inlet and exit. Three circumferential screens were separately mounted on the rotatable assembly. For all configurations data were recorded at each of twelve 30 deg increments of assembly rotation. Experiments were conducted with fan speeds (corrected to station 2 temperature) of 80 or 90 percent of rated condition (7005 rpm) and Reynolds number indices of 0.2 or 0.5. Yaw angle increased between the distortion-generating assembly and the engine inlet. A change in Reynolds number index (RNI) has only a slight effect and a change in speed had no effect on yaw angle distribution. The flow angle was largest in the hub region of the engine inlet.

Pressures and Distortions provides a close-up look at how residents of cities in the developing world are reshaping their environments in response to social, economic, and environmental changes. The cities chronicled range from China through Indonesia to Latin America. In each of the book's four sections, a team of researchers explores how an urban phenomenon of global importance is playing out in a specific city. The studies analyze the impacts of housing shortages on the residents of Shenzhen's vanishing urban villages and Shanghai's deteriorating lanes; the production of self-built housing and neighborhoods in Mexico City (as well as Lima, Rio de Janeiro, and Bogotá); the performance of disaster relief housing constructed in Banda Aceh after the disastrous earthquake and tsunami of 2004; and the reception of Bogota's award-winning new public buildings and spaces by urban residents. Throughout, the authors take a resident-centered view of urbanism and architecture. They interview city dwellers and painstakingly document their living environments as well as their self-built home improvements, using photography and measured drawings. They follow city dwellers with video cameras, recording their day-to-day interactions with urban spaces and with other inhabitants. They carefully chart the stages through which self-built communities are established and consolidated. In each case, the authors use critical examination of policy frameworks and statistical evidence to situate fine-grained observation within a larger context of urban production. Their findings avoid simplistic prescriptions while prompting constructive proposals for governments, NGOs, designers, and communities. Pressures and Distortions is a publication of the Research Program of Rafael Viñoly Architects, a global practice with headquarters in New York. The authors, based in Mexico, Colombia, China, Australia, France, and the US, were selected through a competitive process to receive grants that enabled them to pursue their independent research. The Research Program is proud to present their findings in this handsomely produce volume, containing more than 500 original full-color photographs, plans, and drawings, as well as a DVD with over 100 video and audio recordings.Authors include: Jay Bargmann (Foreword), Ned Kaufman (Editor), Hai Zhang, Marcel Baumler, Richard De Pirro, Ana Rota Garcia Lascuráin, Mayra Gamboa, Juan Carlos Zavala, David O'Brien, Ahmed Iftekhar, Nicolas Tixier, Ida Assefa, Camilo Cifuentes, Sandra Fiori, juL mcOisans, and Céline Rouchy.

Nobody performs better under pressure. Regardless of the task, pressure ruthlessly diminishes our judgment, decision-making, attention, dexterity, and performance in every professional and personal arena. In Performing Under Pressure, Drs. Hendrie Weisinger and J.P. Pawliw-Fry introduce us to the concept of pressure management, offering empirically tested short term and long term solutions to help us overcome the debilitating effects of pressure. Performing Under Pressure tackles the greatest obstacle to personal success, whether in a sales presentation, at home, on the golf course, interviewing for a job, or performing onstage at Carnegie Hall. Despite sports mythology, no one "rises to the occasion" under pressure and does better than they do in practice. The reality is pressure makes us do worse, and sometimes leads us to fail utterly. But there are things we can do to diminish its effects on our performance. Performing Under Pressure draws on research from over 12,000 people, and features the latest research from neuroscience and from the frontline experiences of Fortune 500 employees and managers, Navy SEALS, Olympic and other elite athletes, and others. It offers 22 specific strategies each of us can use to reduce pressure in our personal and professional lives and allow us to better excel in whatever we do. Whether you’re a corporate manager, a basketball player, or a student preparing for the SAT, Performing Under Pressure will help you to do your best when it matters most.
