The fact that the numerical complexity of wavefield simulation is proportional to the size of the discretized model and acquisition geometry, and not to the complexity of the simulated wavefield, is the main impediment within seismic imaging. By turning simulation into a compressive sensing problem—where simulated data is recovered from a relatively small number of independent simultaneous sour...

In this paper, we present a Full-chip CMP simulation system. We discuss three problems in practical use of CMP simulation system: how to handle huge chip data, ECP model accuracy, and how to predict the errors effectively. We propose solutions to the problems as follows: First, we develop a data extraction tool from GDSII. Dummy fill insertion function of this tool can reduce the data size of G...

In many complex domains full scale detailed solutions to problems -plans and ways to implement them -are not possible or practical. Rather than attempt to produce such detailed solutions, we propose an alternative of using scenarios: a set of 'lsnapshots" of the future that outline possible courses of action, actions of foreign processes, and their consequences. In this paper, we present the sc...

A design procedure for subscale airfoils with full-scale leading edges that exhibit full-scale water droplet impingement characteristics in an incompressible, inviscid  ow is presented. The design procedure uses validated airfoil design,  ow analysis, and water droplet impingement simulation codes to accomplish the task. To identify and isolate important design variables in the design, numero...

constructing phase diagram and its subsequent quality lines for lean gas condensate reservoirs is always crucial and challenging topic in reservoir fluid studies. due to small amounts of liquid drop-outs in lean gas condensates at reservoir conditions, full experimental tracking of phase diagram and its relevant quality lines is almost impossible for lean gas condensates.on the other hand, eos ...

Poker poses cognitive challenges like those of warfare, business and other real world domains. This makes poker a good test bed for basic research on how people make Command and Control decisions and for applied research on how systems might help people make better decisions. In this paper, I compare the cognitive challenges of poker and warfare, and present a new suite of “Pared-down Poker” ga...
