The paper describes the history of viscous-inviscid interaction methods, and tries to put them in a modern domain-decomposition context. This history started in 1904, when Ludwig Prandtl presented thèboundary layer' at the Third International Mathematical Congress in Heidelberg. From that moment on, the ow eld around a body was divided in two parts: a thin shear layer where viscosity plays a ro...

Cataract surgery is the most common elective operation performed worldwide (1, 2). The development of new technologies and new surgical techniques and materials lead to less invasive and day care procedures. This in turn encouraged an evolution on the ophthalmic anesthetic strategies, rendering general anesthesia largely unnecessary, so that local techniques have become preferred for cataract s...

Xbox Live Achievements and Gamerscores have become an important part of Xbox 360 gaming and have played an important role in the success of the console. Based on the framework provided by Microsoft, the community has created a rich and intriguing meta-game where the individual games become pieces of a larger whole. For every game released on the system, the developer has to define a number of a...

A necessary and sufficient condition for the existence of the general common positive solution to equations A1X = C1, XB2 = C2, A3XA ∗ 3 = C3, A4XA ∗ 4 = C4 for operators between Hilbert C-modules is established, and an expression for the common positive solution to the equations is derived when the solvability conditions are satisfied. As an application, a new necessary and sufficient conditio...

Agile microand nano-fluidic control is critical to numerous life science and chemical science synthesis as well as kinetic and thermodynamic studies. To this end, we have demonstrated the use of thin film transistor arrays as an active matrix addressing method to control an electrofluidic array. Because the active matrix method minimizes the number of control lines necessary (m + n lines for th...
