Precedence Automata and Languages
Operator precedence grammars define a classical Boolean and deterministic context-free family (called Floyd languages or FLs). FLs have been shown to strictly include the well-known visibly pushdown languages, and enjoy the same nice closure properties. We introduce here Floyd automata, an equivalent operational formalism for defining FLs. This also permits to extend the class to deal with infi...
متن کاملSingle Machine Scheduling Problem with Precedence Constraints and Deteriorating Jobs
This paper considers the single machine scheduling problem with precedence constraints and deteriorating jobs. A mathematical model based on binary integer programming (BIP) is developed. By these precedence constraints, jobs can not start before completion of its all predecessors. The represented model is in two steps, in step one the earliest starting time of each job is computed, then the re...
متن کاملEnsuring excellence in centers of excellence programs.
Studies have found associations between better outcomes and a variety of structural and process criteria that help explain the wide outcome variations that occur across hospitals. In response, Centers of Excellence programs have been developed by multiple third parties. Despite this, programs have yielded disappointing results and can have unintended consequences. To outweigh potential harms, o...
متن کاملProximity and precedence in arithmetic.
How does the physical structure of an arithmetic expression affect the computational processes engaged in by reasoners? In handwritten arithmetic expressions containing both multiplications and additions, terms that are multiplied are often placed physically closer together than terms that are added. Three experiments evaluate the role such physical factors play in how reasoners construct solut...
متن کاملMobility, Networks and Excellence
Better knowledge of what influences researchers’ mobility and how this mobility affects the research community is pivotal, particularly in the globalised society of today. One indicator of the universities’ high degree of globalisation is the fact that three of the five universities that supply most doctoral students to American PhD programmes are now in countries other than the US.1 We are see...
