This paper argues that quantitative process models must be considered essential to support sustained improvement of E-type software evolution processes and summarises some of the experiences gained in the FEAST projects to date. Modelling guidelines are provided.

INTRODUCTION Ritual is intimately connected with the mask, either in the wearing that hides the true face, or in the adoption of a public face. The mask makes the disengagement from ordinary time and the connection to the ancient and repetitive, which is the heart of ritual, psychologically acceptable. Together, ritual and mask facilitate the apprehension of identity and its connections with pa...

Sometimes problems are only hard when the numerical quantities are arbitrary, complicated large integers. When these numerical quantities are limited to being small integers, the problems become efficiently solvable. (One way to formalize this is to consider these quantities as being specified in unary, and ask if the problem becomes polynomial-time solveable.) This is called being “hard in the...

The paper considers lexical reduplications in Russian the perspective of general syntax. goal is to define and fully characterize special surface-syntactic relations [SSyntRels], that is, reduplicative SSyntRels, which appear exclusively syntactic idioms formed by reduplications. operation REDUPL defined, several SSyntRels are introduced. A deductive calculus thereof proposed, based on three pa...
