Wooden foams have been extensively researched in recent years because of their special structure and green features. At the same time, noise pollution is increasing, prompting sound insulation to become another research focus. In this study, a three-factor, five-level orthogonal experiment was designed, 25 sets specimens were produced for testing analysis 19 frequency bands. To measure insulati...

Whistle-blowing is a core topic for any ”ethics” or ”professionalism” course offered for IS/CS/CE/EE majors. This paper documents a real whistle-blowing case that is ideal for use in teaching. The incident is set in the computing industry, specifically in the supply of micro-electronic chips for use in safety-critical systems. The incident is well documented, with decisions in both a criminal c...

In this article, we study the numerical approximation of a Newtonian model for film blowing. We prove that the approximations for the bubble radius, and the film thickness, converges to the true solution and establish the convergence rates. Numerical results are given which demonstrate the theoretical results obtained. c © 2005 Elsevier Science Ltd. All rights reserved. Keywords—Film blowing, F...

One of the reasons why software projects suffer from high failure rate is that employees working on the project are often reluctant to blow the whistle informing the upper-level management about the failing status of the project. In this study, we examine the impacts of organizational commitment, interpersonal closeness, and Confucian ethics on the employees’ whistle-blowing intentions in the E...

Numerical simulations are performed using a Reynolds-averaged Navier-Stokes (RANS) flow solver for a circulation control airfoil. 2D and 3D simulation results are compared to a circulation control wind tunnel test conducted at the NASA Langley Basic Aerodynamics Research Tunnel (BART). The RANS simulations are compared to a low blowing case with a jet momentum coefficient, Cμ, of 0.047 and a hi...

1.1. Crash course in blowing up. Last time I began to talk about blowing up. Let X be a scheme, and I ⊂ OX a sheaf of ideals on X. (Technical requirement automatically satisfied in our situation: I should be a coherent sheaf, i.e. finitely generated.) Here is the “universal property” definition of blowing-up. Then the blow-up of OX along I is a morphism π : X̃ → X satisfying the following univer...
