TL;DR: The boundary layer transition under instationary afflux conditions as present in the stages of turbomachines is investigated in this article by means of time-space distributions of the turbulent spots during transition and schematic drawings of the instantaneous boundary layer thicknesses.
Abstract: The boundary layer transition under instationary afflux conditions as present in the stages of turbomachines is investigated. A model for the transition process is introduced by means of time-space distributions of the turbulent spots during transition and schematic drawings of the instantaneous boundary layer thicknesses. To confirm this model, measurements of the transition with zero and favorable pressure gradient are performed.Copyright © 1982 by ASME

TL;DR: Making text editors more like computer games may seem ridiculous on the surface, but these "games" use basic motivational techniques-something designers of application systems have overlooked.
Abstract: 35 Using Handwriting Action to Construct Models of Engineering Objects Mamoru Hosaka and Fumihiko Kimura With this symbol recognition technique, handwritten engineering drawings can be used as direct computer input for generating machine models of design objects. 49 The Adventure of Getting to Know a Computer John M. Carroll Making text editors more like computer games may seem ridiculous on the surface, but these \"games\" use basic motivational techniques-something designers of application systems have overlooked.

TL;DR: Theoretical and experimental investigations of the acoustic frequency response of circular backplate electret microphones are discussed and measured and calculated responses show very good agreement.
Abstract: Theoretical and experimental investigations of the acoustic frequency response of circular backplate electret microphones are discussed. In particular the sensitivity to air-borne sound and the vibration sensitivity of the transducers are studied for different parameters such as membrane tension and radius. Furthermore, the influence of hole geometry of the backplate and the effect of ambient pressure on the microphone damping. Measured and calculated responses show very good agreement.

TL;DR: In this article, the application of optimal control theory to minimum weight design of continuous one-dimensional structural elements subject to eigenvalue constraints is discussed, and necessary conditions for optimal weight design are derived.
Abstract: The application of optimal control theory to minimum weight design of continuous one-dimensional structural elements subject to eigenvalue constraints is discussed. If not only the value of an eigenvalue is prescribed but also its position in the sequence of the ordered eigenvalues—for example, the critical buckling load of a column—the corresponding optimal control problem is shown to include necessarily all eigenvalues. Considering the unspecified eigenvalues as free parameters, necessary conditions for minimum weight design are derived. These conditions are compared with those obtained by use of variational methods. Attention is focused on the special case of multimodal solutions.

TL;DR: Although there is general agreement on the fact that the new protectionism of the industrialised countries is damaging to developing countries, the majority of the latter show hardly any interest in a return to the classical GATT system.
Abstract: Although there is general agreement on the fact that the new protectionism of the industrialised countries is damaging to developing countries, the majority of the latter show hardly any interest in a return to the classical GATT system Prof Korner provides an explanation for this apparently paradoxical attitude on which be bases his case for a reform of the existing system of international trade
