The Design and Implementation of a Log-Structured File System

by Mendel Rosenblum, John K. Ousterhout - ACM Transactions on Computer Systems , 1992
"... This paper presents a new technique for disk storage management called a log-structured file system. A logstructured file system writes all modifications to disk sequentially in a log-like structure, thereby speeding up both file writing and crash recovery. The log is the only structure on disk; it ..."

Stable recovery of sparse overcomplete representations in the presence of noise

by David L. Donoho, Michael Elad, Vladimir N. Temlyakov - IEEE TRANS. INFORM. THEORY , 2006
"... Overcomplete representations are attracting interest in signal processing theory, particularly due to their potential to generate sparse representations of signals. However, in general, the problem of finding sparse representations must be unstable in the presence of noise. This paper establishes t ..."

the possibility of stable recovery under a combination of sufficient sparsity and favorable structure of the overcomplete system. Considering an ideal underlying signal that has a sufficiently sparse representation, it is assumed that only a noisy version of it can be observed. Assuming further

Structure recovery by part assembly

by Chao-hui Shen, Hongbo Fu, Kang Chen, Shi-min Hu - SIGGRAPH Asia , 2012
"... RGB images (lower left), our approach is able to faithfully recover their underlying structures (yellow) by assembling suitable parts (red) in the repository models (blue). This paper presents a technique that allows quick conversion of acquired low-quality data from consumer-level scanning devices ..."

to high-quality 3D models with labeled semantic parts and meanwhile their assembly reasonably close to the underlying geometry. This is achieved by a novel structure recovery approach that is essentially local to global and bottom up, enabling the creation of new structures by assembling existing labeled

Reliable Multicast Transport Protocol (RMTP)

by Sanjoy Paul, Krishan K. Sabnani, John C. Lin, Supratik Bhattacharyya
"... This paper presents the design, implementation and performance of a reliable multicast transport protocol called RMTP. RMTP is based on a hierarchical structure in which receivers are grouped into local regions or domains and in each domain there is a special receiver called a Designated Receiver (D ..."

Geometric reasoning for single image structure recovery

by David C. Lee, Martial Hebert, Takeo Kanade - In proc. CVPR , 2009
"... We study the problem of generating plausible interpretations of a scene from a collection of line segments automatically extracted from a single indoor image. We show that we can recognize the three dimensional structure of the interior of a building, even in the presence of occluding objects. Sever ..."
Abstract - Cited by 94 (11 self) - Add to MetaCart
. Several physically valid structure hypotheses are proposed by geometric reasoning and verified to find the best fitting model to line segments, which is then converted to a full 3D model. Our experiments demonstrate that our structure recovery from line segments is comparable with methods using full image

AUTOMATIC STRUCTURE RECOVERY AND VISUALIZATION

by Michela Farenzena, Andrea Fusiello, Riccardo Gherardi, Roberto Toldo
"... We describe an automated pipeline for the reconstruction and rendering of three dimensional objects, with particular emphasys for urban environments. Our system can robustly recover 3D points and cameras from uncalibrated views, without manual assistance. The reconstructed structure is augmented by ..."

AUTOMATIC CAMERA ORIENTATION AND STRUCTURE RECOVERY WITH

by R. Gherardi, R. Toldo, V. Garro, A. Fusiello
"... SAMANTHA is a software capable of computing camera orientation and structure recovery from a sparse block of casual images without human intervention. It can process both calibrated images or uncalibrated, in which case an autocalibration routine is run. Pictures are organized into a hierarchical tr ..."

"... 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 ..."
Abstract - Cited by 422 (2 self) - Add to MetaCart
. Thus, we examine how changes in credit spreads respond to proxies for both changes in the probability of future default and for changes in the recovery rate. Separately, recent empirical studies find that the corporate bond market tends to have relatively high transactions costs and low volume. 1

Structure recovery via hybrid variational surface approximation

by Jianhua Wu, Leif Kobbelt - Computer Graphics Forum (Proc. Eurographics
"... Aiming at robust surface structure recovery, we extend the powerful optimization technique of variational shape approximation by allowing for several different primitives to represent the geometric proxy of a surface region. While the original paper only considered planes, we also include spheres, c ..."

Structural Recovery of Face Value at Default

by Rajiv Guha, Ro Sbuelz , 2002
"... A Recovery of Face Value at Default (RFV) means receiving the same fractional recovery of par at default for bonds of the same issuer and seniority, regardless of remaining maturity. We find that RFV in a parsimonious structural credit risk model has a profound impact on hedging interest rate risk a ..."
