Abstract: Likely disconnections or system-level-impact producing slowdown in a flow parameter in a network can be identified by annotating a graph representing the network with a weight to edges of a graph representing the network. The weight can be linearly or non-linearly proportional to the inverse of the severity of the impact, and/or linearly or non-linearly proportional to the inverse of the likelihood of disconnection. Minimal cut sets needed to generate a disconnection in the network are identified from the annotated network based on the weights on the edges. Subsets of each minimal cut set are generated and evaluated during a simulation. The subsets can correspond to almost isolated scenarios for the network. The scope of the simulations can be reduced by selecting the minimal cut sets employing the weight.

Abstract: A system and method implementing a hierarchical approach to RTM (Reverse Time Migration) seismic imaging at different granularity in space and time. An RTM seismic imaging algorithm utilizes RTM technique to convert a parallel problem into one solved using massive domain partitioning. In the method, a coarse-grain grid for the 3D volume of the geological subsurface structure under investigation is initially processed, permitting the RTM imaging process to be performed faster and produces lower level seismic image for inspection. Criteria are then applied to the first level of seismic image to determine whether to reject the image or whether a finer resolution seismic imaging is needed. In the case of finer resolution is needed, RTM resolution for the target volume is adjusted accordingly and RTM imaging process is applied with the new resolution. The process is repeated until either the image is accepted or rejected.

Abstract: A conductive brush, or stylus, for use with touch screen computing devices. The bristles or filaments are attached to an electrically conductive ferrule, so that even when the brush is pressed against the tablet to make the bristles splay apart, the conductive ferrule itself maintains electrical communication with the tablet. The brush thus allows users to conduct paint operations in an uninterrupted manner, even when its bristles spread apart. Further, this ferrule can be made removable so that users can swap out different brush heads quickly and easily. Additionally, the ferrule has at least a portion that is flexible, deforming visibly upon application of pressures commonly achieved during a typical painting operation. This deformation at least partially absorbs stresses on the filaments, preventing them from splaying apart excessively during painting, and thus helping to prevent loss of detection by the tablet and/or undesired visual effects.
