متن کاملThree-Dimensional Sacrificial Etching
In MEMS fabrication micro-mechanical components have to be partially released from a substrate. Selectively etching away sacrificial layers, such that a free standing structure remains, is a widely used technique for this purpose. Free standing structures allow MEMS devices to induce or to sense mechanical movements or vibrations. During sacrificial etching lower etch rates than the blanket one...
متن کاملGlobal Warming: the Sacrificial Temptation
The claimed unanimity of the scientific community about the human culpability for global warming is questioned. Up today there exists no scientific proof of human culpability. It is not the number of authors of a paper, which validates its scientific content. The use of probability to assert the degree of certainty with respect the global warming problem is shown to be misleading. The debate ab...
متن کاملNarrativas da mobilidade: comunicação, cultura e produção em espaços informacionais
This research stems from the issue of the mobility phenomenon, through the pathway tread by subjects in need of connection and access to uninterrupted information flow. In this informational, cultural and technological context, the presence of mobile dispositives stands out, especially cell phones. Such artifacts, which contain not only voice services, but texting information, and Internet conn...
متن کاملSacrificial Learning in Nonlinear Perceptrons
Using the cavity method we consider the learning of noisy teachergenerated examples by a nonlinear student perceptron. For insufficient examples and weak weight decay, the activation distribution of the training examples exhibits a gap for the more difficult examples. This illustrates that the outliers are sacrificed for the overall performance. Simulation shows that the picture of the smooth e...
