A Field Study of the Software Design Process for Large Systems

by Bill Curtis, Herb Krasner, Neil Iscoe - Communications of the ACM , 1988
"... 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, and communication ..."

The Determinants of Credit Spread Changes.

by Pierre Collin-Dufresne , Robert S Goldstein , J Spencer Martin , Gurdip Bakshi , Greg Bauer , Dave Brown , Francesca Carrieri , Peter Christoffersen , Susan Christoffersen , Greg Duffee , Darrell Duffie , Vihang Errunza , Gifford Fong , Mike Gallmeyer , Laurent Gauthier , Rick Green , John Griffin , Jean Helwege , Kris Jacobs , Chris Jones , Andrew Karolyi , Dilip Madan , David Mauer , Erwan Morellec , Federico Nardari , N R Prabhala , Tony Sanders , Sergei Sarkissian , Bill Schwert , Ken Singleton , Chester Spatt , René Stulz - Journal of Finance , 2001
"... 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 are ..."

A New Point Matching Algorithm for Non-Rigid Registration

by Haili Chui, Anand Rangarajan , 2002
"... Feature-based methods for non-rigid registration frequently encounter the correspondence problem. Regardless of whether points, lines, curves or surface parameterizations are used, feature-based non-rigid matching requires us to automatically solve for correspondences between two sets of features. I ..."
Abstract - Cited by 356 (3 self) - Add to MetaCart
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

Shape Transformation Using Variational Implicit Functions

by Greg Turk , James F. O'Brien , 1999
"... Traditionally, shape transformation using implicit functions is performed in two distinct steps: 1) creating two implicit functions, and 2) interpolating between these two functions. We present a new shape transformation method that combines these two tasks into a single step. We create a transforma ..."
Abstract - Cited by 203 (6 self) - Add to MetaCart
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

Coded Exposure Photography: Motion Deblurring using a Fluttered Shutter

by Ramesh Raskar, Amit Agrawal, Jack Tumblin, Ramesh Raskar, Amit Agrawal, Jack Tumblin - In Proceedings of SIGGRAPH 2006
"... In a conventional single-exposure photograph, moving objects or moving cameras cause motion blur. The exposure time defines a temporal box filter that smears the moving object across the image by convolution. This box filter destroys important high-frequency spatial details so that deblurring via de ..."
Abstract - Cited by 162 (22 self) - Add to MetaCart
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

Numerical Simulation of the Spreading of Droplets

by P. H. Gaskell, P. Jimack, M. Sellier, H. M. Thompson, M. Decré
"... 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 phenome ..."

Myosin is involved in postmitotic cell spreading

by L. P. Cramer, T. J. Mitchison - J. Cell , 1995
"... Abstract. We have investigated a role for myosin in postmitotic Potoroo tridactylis kidney (PtK2) cell spreading by inhibitor studies, time-lapse video microscopy, and immunofluorescence. We have also determined the spatial organization and polarity of actin filaments in postmitotic spreading cells. ..."
Abstract - Cited by 51 (2 self) - Add to MetaCart
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

Streaming first story detection with application to Twitter

by Sasa Petrovic, Miles Osborne, Victor Lavrenko - IN PROCEEDINGS OF THE 11TH ANNUAL CONFERENCE OF THE NORTH AMERICAN CHAPTER OF THE ASSOCIATION FOR COMPUTATIONAL LINGUISTICS (NAACL HLT 2010 , 2010
"... 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 pres ..."

Negative staining of thinly spread cells and associated virus

by Donald F. Parsons, From Ontario - J. Cell Biol , 1963
"... The first demonstration of intracytoplasmic virus by negative staining was that of Horne and Nagington (9) who subjected poliovirus-infected cells to freezing and thawing and negatively stained a suspension of the fragments. Dales (5) examined the attachment of some viruses to the cell surface by th ..."

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
