This paper deals with tolerance to timing faults in time-constrained systems. TAFT (Time Aware Fault-Tolerant) is a recently devised approach which applies tolerance to timing violations. According to TAFT, a task is structured in a pair, to guarantee that deadlines are met (although possibly offering a degraded service) without requiring the knowledge of tasks attributes difficult to estimate ...

The sharply contrasting experiences of John G. Roberts, Jr. and William Howard Taft with the Article II, Section 2 appointments process illustrate that the long view of history is governed by perspective. William Howard Taft, the twenty-seventh President, also later became the tenth Chief Justice of the United States. Taft was nominated for the position of Chief Justice of the Supreme Court—a p...

The main goal is to study the Hopf algebra structure on quivers. The main result obtained by C. Cibils and M. Rosso is improved. That is, in the case of infinite dimensional isotypic components it is shown that the path coalgebra kQ admits a graded Hopf algebra structure if and only if Q is a Hopf quiver. All nonisomorphic point path Hopf algebras and point co-path Hopf algebras are found. The ...
