The problems of designing large software systems were studied through interviewing personnel from 17 large projects. A layered behavioral model is used to analyze how three lgf these problems-the thin spread of application domain knowledge, fluctuating and conflicting requirements

ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression

developed an algorithm---the TPS-RPM algorithm---with the thin-plate spline (TPS) as the parameterization of the non-rigid spatial mapping and the softassign for the correspondence. The performance of the TPS-RPM algorithm is demonstrated and validated in a series of carefully designed synthetic experiments

specify the locations of shape boundaries and positivevalued constraints are placed along the normal direction in towards the center of the shape. We then invoke a variational interpolation technique (the 3D generalization of thin-plate interpolation), and this yields a single implicit function in 3D

deconvolution becomes an illposed problem. Rather than leaving the shutter open for the entire exposure duration, we ¨flutter¨the camera´s shutter open and closed during the chosen exposure time with a binary pseudo-random sequence. The flutter changes the box filter to a broad-band filter that preserves high

The fluid dynamical behaviour of thin liquid films, whether forced to spread over a solid surface or deposited/printed as a distinct pattern, is of enormous significance to manufacturing industry and practice. Such flows involve the presence of a free surface, dynamic wetting and interfacial

actin filaments in spreading edges are part of actin bundles that are also found in long, thin, structures that are connected to spreading edges and substrate (retraction fibers), and that 90 % of this actin is oriented with barbed ends in the direction of spreading. The remaining actin in spreading

With the recent rise in popularity and size of social media, there is a growing need for systems that can extract useful information from this amount of data. We address the problem of detecting new events from a stream of Twitter posts. To make event detection feasible on web-scale corpora, we

by the negative staining of whole mounts of cells subjected to osmotic shock. Whittaker and Horne (15) examined normal cell components by the negative staining of fractions of tissue homogenates separated by centrifugation. Methods of negative staining of thin sections of frozen or frozen-dried tissue have been

The global spread of highly
