"... igital systems have been entrusted with increasingly more critical responsibilities, requiring high dependability. Often the use of high-quality components and design techniques does not sufficiently reduce the likelihood of system failures, and means must be provided to tolerate faults in the syste ..."

It examines failures, faults, and errors in digital systems and defines measures of dependability, which dictate and evaluate fault-tolerance strategies for different classes of applications. The various

Among the most frequent questions that the public and decision makers ask climate scientists are: What do we know about past climate? What are our uncertainties? What do we know about the causes of climate variations and change? What are our uncertainties on causes? The scientific methods of climate re-analysis (henceforth, reanalysis) and attribution play important roles in helping to address such questions. This Chapter is intended to provide readers with an initial foundation for understanding the nature and scientific roles of reanalysis and attribution, as well as their potential relevance for applications and decision making. These subjects are then discussed in detail in the following chapters.

Graphical representations for probabilistic relationships have recently received considerable attention in A1. Qualitative probabilistic networks abstract from the usual numeric representations by encoding only qualitative relationships, which are inequality constraints on the joint probability distribution over the variables. Although these constraints are insufficient to determine probabilities uniquely, they are designed to justify the deduction of a class of relative likelihood conclusions that imply useful decision-making properties. Two types of qualitative relationship are defined, each a probabilistic form of monotonicity constraint over a group of variables. Qualitative influences describe the direction of the relationship between two variables. Qualitative synergies describe interactions among influences. The probabilistic definitions chosen justify sound and efficient inference procedures based on graphical manipulations of the network. These procedures answer queries about qualitative relationships among variables separated in the network and determine structural properties of optimal assignments to decision variables.
TAXONOMY OF THE FUNDAMENTAL CONCEPTS OF METAPROGRAMMING
"... Abstract. Although widely used in software engineering, metaprogramming is often misunderstood. The researchers often disagree what concepts characterize metaprogramming. The concepts of metaprogramming are often used without acknowledging the usage of metaprogramming itself. We overview the example ..."
