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 ..."

, Stanton, and Whitelaw (1997), who find that a 3-factor model explains over 90 percent of Ginnie Mae yields, but that the remaining variation apparently cannot be explained by the changes in the yield curve. 2 In contrast, our multiple-factor model explains only about one-quarter of the variation in credit

Remaining Useful Life Prediction of Rolling Element Bearings Based On Health State Assessment

by Zhiliang Liu, Ming J. Zuo, Longlong Zhang
"... Remaining useful life (RUL) prediction is one of key technologies to realize prognostics and health management that is being widely applied in many industrial systems to ensure high system availability over their life cycles. The present work proposes a data-driven method of RUL prediction based on ..."

Remaining Useful Life Estimation of Critical Components With Application to Bearings

by K. Medjaher, D. A. Tobon-mejia, N. Zerhouni - IEEE TRANSACTIONS ON RELIABILITY , 2012
"... Prognostics activity deals with the estimation of the Remaining Useful Life (RUL) of physical systems based on their current health state and their future operating conditions. RUL estimation can be done by using two main approaches, namely model-based and data-driven approaches. The first approach ..."

Vibration-based Approach to Lifetime Prediction of Washing Machines

by Jiří Vass, Robert B. R, Sami Kara, Hartmut Kaebernick
"... This paper presents a vibration method for remaining life estimation of components in washing machines. Vibration signals were measured on electric motors during an accelerated lifetime test. Significant frequency bands are identified using a spectral comparison based on the Constant Percentage Band ..."

NAÏVE BAYSIAN CLASSIFIER FOR ON-LINE REMAINING USEFUL LIFE PREDICTION OF DEGRADING BEARINGS

by Francesco Di Maio, Selina S. Y. Ng, Kwok Leung Tsui, Enrico Zio
"... In this paper, the estimation of the Residual Useful Life (RUL) of degraded thrust ball bearings is made resorting to a data-driven stochastic approach that relies on an iterative Naïve Bayesian Classifier (NBC) for regression task. NBC is a simple stochastic classifier based on applying Bayes ’ the ..."

Anonymous Hierarchical Identity-Based Encryption (Without Random Oracles). In: Dwork

by Xavier Boyen , Brent Waters - CRYPTO 2006. LNCS, , 2006
"... Abstract We present an identity-based cryptosystem that features fully anonymous ciphertexts and hierarchical key delegation. We give a proof of security in the standard model, based on the mild Decision Linear complexity assumption in bilinear groups. The system is efficient and practical, with sm ..."

model, in addition to being the first to realize fully anonymous HIBE at all levels in the hierarchy. Introduction The cryptographic primitive of identity-based encryption allows a sender to encrypt a message for a receiver using only the receiver's identity as a public key. Recently, there has

Materials for an exploratory theory of the network society.

by Manuel Castells , Anthony Giddens , Alain Touraine , Anthony Smith , Benjamin Barber , Peter Hall , Roger-Pol Droit , Sophie Watson , Frank Webster , Krishan Kumar , David Lyon , Craig Calhoun , Jeffrey Henderson , Ramon Ramos , Jose E Rodrigues-Ibanez , Jose F Tezanos , Mary Kaldor , Stephen Jones , Christopher Freeman - The British Journal of Sociology , 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

to perform a useful function it is phased out from the network, and the network rearranges itself -as cells do in biological processes. Some nodes are more important than others, but they all need each other as long as they are within the network. And no nodal domination is systemic. Nodes increase

Bearing Health Condition Monitoring: Frequency Domain Analysis

by Shanmukha Priya , V , M R Ramesh , Vps Naidu
"... ABSTRACT: Condition monitoring is used to frequently monitor the parts of an engine. Since the failures are predicted in advance, the lifetime of the machine is increased, thereby minimizing the maintenance costs. Among the many techniques used for condition monitoring such as static, dynamics, the ..."

A Bayesian Framework for Remaining Useful Life Estimation

by Bhaskar Saha, Kai Goebel, Scott Poll, Jon Christophersen
"... The estimation of remaining useful life (RUL) of a faulty component is at the center of system prognostics and health management. It gives operators a potent tool in decision making by quantifying how much time is left until functionality is lost. This is especially true for aerospace systems, where ..."

P275-WE FLUORESCENCE LIFETIME ANALYSIS OF SINGLE HYDROCARBON-BEARING FLUID INCLUSIONS – A PARAGENETIC PERSPECTIVE

by Nigel J. F. Blamey, Alan G. Ryder, Martin Feely, Peter Owens
"... UV fluorescence is commonly used as a first-pass visualisation tool for the study of Hydrocarbon bearing Fluid Inclusions (HCFI). Fluorescence colour is commonly used as a guide to estimate API gravity (Bodnar, 1990) and allow visual discrimination of single or multiple HCFI generations into a parag ..."
