Safety/Reliability engineering did not develop as a unified discipline, but grew out of the
integration of a number of activities, previously the province of various branches of engineering.
Since no human activity can enjoy zero risk, and no equipment has a zero rate of failure,
there has emerged a safety technology for optimizing risk. This attempts to balance the risk
of a given activity against its benefits and seeks to assess the need for further risk reduction
depending upon the cost.
The deﬁnitions of the basic concepts, rules, and constraints of centering theory involve underspeciﬁed notions such as ‘previous utterance’, ‘realization’, and ‘ranking’. We attempted to ﬁnd the best way of deﬁning each such notion among those that can be annotated reliably, and using a corpus of texts in two domains of practical interest. Our main result is that trying to reduce the number of utterances without a backwardlooking center (CB) results in an increased number of cases in which some discourse entity, but not the CB, gets pronominalized, and viceversa.
(BQ) Ebook Multithreading in C# 5.0 Cookbook is an easy-to-understand guide to the most puzzling programming problems. This book will guide you through practical examples dedicated to various aspects of multithreading in C# on Windows and will give you a good basis of practical knowledge which you can then use to program your own scalable and reliable multithreaded applications.

Medicaid Services (CMS) under the Clinical Laboratory Improvement Act
(CLIA). The objective of the CLIA program is to ensure quality laboratory
testing by establishing standards for accuracy, reliability, and timeliness of
patient test results. A laboratory is defined as any facility that tests
specimens derived from humans for the assessment of health or the
diagnosis, prevention, and treatment of disease.
CLIA regulations, published in 1992, are based on the complexity of the test
method; thus, the more complicated the test, the more stringent the
A comparative study of thermodynamic and kinetic aspects of Cu(II) and Ni(II) binding at the N-terminal binding site of human and bovine serum albumins (HSA and BSA, respectively) and short peptide analogues was performed using potentiometry and spectroscopic techniques. It was found that while qualitative aspects of interaction (spectra and structures of complexes, order of reactions) could be reproduced, the quantitative parameters (stability and rate constants) could not.
Chapter 13b: Answer key about COST MANAGEMENT
1. Answer: c Both the cost and accuracy of parametric models vary widely. They are most likely to be reliable when the historical information used to develop the model was accurate, the parameters used in the model are readily quantiﬁable, and the model is scalable (i.e., it works as well for a very large project as for a very small one). 2. Answer: b An analogous estimate is one that is arrived at by taking a project or part of a project that is already completed and adjusting the cost on the basis...
This application note introduces the concepts of digital modulation used in many communications systems today. Emphasis is placed on explaining the tradeoffs that are made to optimize efficiencies in system design. Most communications systems fall into one of three categories: bandwidth efficient, power efficient, or cost efficient. Bandwidth efficiency describes the ability of a modulation scheme to accommodate data within a limited bandwidth. Power efficiency describes the ability of the system to reliably send information at the lowest practical power level.
NETWORKED SYSTEMS RELIABILITY
Many physical problems (e.g., computer networks, piping systems, and power grids) can be modeled by a network. In the context of this chapter, the word network means a physical problem that can be modeled as a mathematical graph composed of nodes and links (directed or undirected) where the branches have associated physical parameters such as ﬂow per minute, bandwidth, or megawatts. In many such systems, the physical problem has sources and sinks or inputs and outputs, and the proper operation is based on connection between inputs and outputs....

The serious challenge facing the world today, in obtaining enough energy for growing population and in controlling the carbon emission caused by fossil fuel use, calls for nuclear energy as an alternative power source. This book presents research work and technical experience from several power plants and research institutions around the world from practical prospective.
Increased Reliability, Availability, and Scalability
Reliability, availability, and scalability are important parameters of network operating systems. An operating system should be able to work 24 hours a day, seven days a week, and the administrator should not be required to perform a reboot after every configuration change; in addition, the operating system should be able to correct itself when problems occur. Finally, an operating system should be able to grow in order to meet the demands of expanding businesses.
Semi-active (SA) suspensions are those which otherwise passively generated damping or spring
forces modulated according to a parameter tuning policy with only a small amount of control effort.
SA suspensions, as their name implies, fill the gap between purely passive and fully active suspensions
and offer the reliability of passive systems, yet maintain the versatility and adaptability of
fully active devices.

A compact model for magnetic tunnel junction (MTJ) switched by thermally assisted Spin transfer torque (TAS + STT)
Weisheng Zhao1,2*, Julien Duval1,2, Jacques-Olivier Klein1,2 and Claude Chappert1,2
Abstract Thermally assisted spin transfer torque [TAS + STT] is a new switching approach for magnetic tunnel junction [MTJ] nanopillars that represents the best trade-off between data reliability, power efficiency and density.
In this paper the spline approximation was applied to the empirical vertical profiles of oceanographic parameters such as temperature, salinity or density to obtain a more precise and reliable result of interpolation. Our experiments with the case of observed temperature profiles in Eastern Sea show that the cubic polynomial spline method has a higher reliability and precision in a comparison with the linear interpolation and other traditional methods. The method was realized as a subroutine in our programs for oceanographic data management and manipulation.
We present a novel probabilistic classiﬁer, which scales well to problems that involve a large number of classes and require training on large datasets. A prominent example of such a problem is language modeling. Our classiﬁer is based on the assumption that each feature is associated with a predictive strength, which quantiﬁes how well the feature can predict the class by itself. The predictions of individual features can then be combined according to their predictive strength, resulting in a model, whose parameters can be reliably and efﬁciently estimated.
Recognizing entailment at the lexical level is an important and commonly-addressed component in textual inference. Yet, this task has been mostly approached by simpliﬁed heuristic methods. This paper proposes an initial probabilistic modeling framework for lexical entailment, with suitable EM-based parameter estimation. Our model considers prominent entailment factors, including differences in lexical-resources reliability and the impacts of transitivity and multiple evidence.
This paper proposes a new discriminative training method in constructing phrase and lexicon translation models. In order to reliably learn a myriad of parameters in these models, we propose an expected BLEU score-based utility function with KL regularization as the objective, and train the models on a large parallel dataset.
