Improvements in micro-fabrication techniques are enabling Micro-Electro-Mechanical-Systems to be constructed with sub-micron feature sizes. At this scale, even at standard atmospheric conditions, the flow is in the transition regime. This paper considers the range 0.1 < Kn < 1, where non-equilibrium effects can be appreciable, and specifically illustrates problems involving non-planar surfaces ...

When you apply for a job or come up for tenure, you will be asked to submit a teaching statement. Of course in some instances, a teaching statement is not a serious factor in the hiring or the tenure process. An institution requires a statement simply to send the message that it regards teaching as important. And it is no doubt the case that a poor teaching statement can hurt more than a strong...

These are lecture notes from a graduate course for Computer Science graduate students at Princeton University in Fall 2013 and Fall 2014. (The course also attracts undergrads and non-CS grads and total enrollment in 2014 was 35.) The course assumes prior knowledge of algorithms at the undergraduate level. This new course arose out of thinking about the right algorithms training for CS grads tod...

At present, there is considerable excitement in analyzing and harnessing large graphs, in particular social and information networks. This is spurred by numerous applications including viral marketing, epidemiology, spread of innovation, social event organization, and event detection and tracking, to name a few from various domains. Unprecedented availability of network and social media data ha...

The local discontinuous Galerkin method for the numerical approximation of the time-harmonic Maxwell equations in a low-frequency regime is introduced and analyzed. Topologically nontrivial domains and heterogeneous media are considered, containing both conducting and insulating materials. The presented method involves discontinuous Galerkin discretizations of the curl-curl and grad-div operato...

B kann das Verhalten thermischer Neutronen in Substanzen, deren Streuquerschnitt groß gegen den Einfangquerschnitt ist, mit Hilfe der klassischen Diffusionstheorie beschrieben werden2. Für einen Strom thermischer Neutronen gilt daher die Beziehung j — D grad n ( j Stromdichte, D Diffusionskoeffizient, n Dichte der Neutronen). Durchsetzt ein solcher Neutronenstrom die Grenzschicht zweier Medien,...

Dieser Beitrag stellt Blickgesten als ein neues Konzept für die Bedienung von Computersystemen mit den Augen vor. Blickgesten sind immun gegen Kalibrierungsdrift und unempfindlich für Genauigkeitsfehler. Sie eignen sich besonders für Augensteuerung aus der Entfernung. Es konnte gezeigt werden, dass Menschen in der Lage sind, willentlich kontrollierte Gesten mit dem Blick auszuführen. Des Weiter...

In this paper we focus on the theoretical parameters that should be taken into consideration when Greek idioms are to be taught in a foreign language context. Given the fact that Modern Greek is characterized by a high degree of idiomaticity, it is impossible for the foreign students not to engage in idioms not only in ordinary speech but even in academic texts. Hence, idiom instruction involve...
