Credit Ratings Failures and Policy Options [PDF]
This paper examines the role of credit rating agencies in the subprime crisis that triggered the 2007-2008 financial turmoil. We focus on two aspects of ratings that contributed to the boom and bust of the market for structured debt: rating inflation and coarse information disclosure. The paper discusses how regulation can be designed to mitigate these

Failure rate properties of parallel systems [PDF]
AbstractWe study failure rate monotonicity and generalised convex transform stochastic ordering properties of random variables, with an emphasis on applications. We are especially interested in the effect of a tail-weight iteration procedure to define distributions, which is equivalent to the characterisation of moments of the residual lifetime at a ...

Analysis of System-Failure Rate Caused by Soft-Errors using a UML-Based Systematic Methodology in an SoC [PDF]
This paper proposes an analytical method to assess the soft-error rate (SER) in the early stages of a System-on-Chip (SoC) platform-based design methodology.

The EuroHeart Failure Survey programme—a survey on the quality of care among patients with heart failure in Europe Part 2: treatment [PDF]
National surveys suggest that treatment of heart failure in daily practice differs from guidelines and is characterized by underuse of recommended medications.

Railway infrastructure is generally classified as either fixed or movable infrastructure assets. Failure in any of the assets could lead to the complete shutdown and disruption of the entire system, economic loss, inconvenience to passengers and the ...

Selected Aspects of Analyses of Failure Rates of Active Safety Systems in Buses
The article outlines the methodology of statistical analysis of failure rate of active safety systems in buses. The theoretical discussion is illustrated with calculations carried out on the basis of empirical data covering a four-year period of ...

Time dependent fracture under unloading in a fiber bundle model [PDF]
We investigate the fracture of heterogeneous materials occurring under unloading from an initial load. Based on a fiber bundle model of time dependent fracture, we show that depending on the unloading rate the system has two phases: for rapid unloading ...

Failure Rates for Aging Aircraft [PDF]
In any consideration of the operating condition, the age of a particular aircraft is a major factor. Much attention is focused on planes which are aged, that is, aircraft with chronological age or accumulated hours of use beyond a threshold. Being aged is a state, and should be distinguished from aging, which is a process of degradation with use.

A Generalization of the Exponential-Poisson Distribution
The two-parameter distribution known as exponential-Poisson (EP) distribution, which has decreasing failure rate, was introduced by Kus (2007). In this paper we generalize the EP distribution and show that the failure rate of the new distribution can be ...

Non-Newtonian Rheology of Igneous Melts at High Stresses and Strain Rates: Experimental Results for Rhyolite, Andesite, Basalt, and Nephelinite [PDF]
The stress-strain rate relationships of four silicate melt compositions (high-silica rhyolite, andesite, tholeiitic basalt, and nephelinite) have been studied using the fiber elongation method.
