Step – By – Step
Approaches to formalisation of medical guidelines can be divided into model–centric and document–centric. While model–centric approaches dominate in the development of clinical decision support applications, document–centric, mark–up–based formalisation is suitable for application tasks requiring the 'literal' content of the document to be transferred into the formal model. Examples of such tas...
متن کاملStep by Step
In most dynamic traffic congestion models, congestion tolls must vary continuously over time to achieve the full optimum. This is also the case in Vickrey's (1969) ‘bottleneck model’. To date, the closest approximations of this ideal in practice have so-called ‘step tolls’, in which the toll takes on different values over discrete time intervals, but is constant within each interval. Given the ...

This paper considers a dynamic model of industry location in which there is a tension between two forces. First, there is the agglomerating force of preference of intermediate input variety that tends to keep an industry at its original location. Second, other location factors matter and these tend to pull the industry in the direction of a new location. A crucial aspect of the model is that th...

متن کاملTinycals: Step by Step Tacticals
Most of the state-of-the-art proof assistants are based on procedural proof languages, scripts, and rely on LCF tacticals as the primary tool for tactics composition. In this paper we discuss how these ingredients do not interact well with user interfaces based on the same interaction paradigm of Proof General (the de facto standard in this field), identifying in the coarse-grainedness of tacti...
