Labeling Workflow Views with Fine-Grained Dependencies
This paper considers the problem of efficiently answering reachability queries over views of provenance graphs, derived from executions of workflows that may include recursion. Such views include composite modules and model fine-grained dependencies between module inputs and outputs. A novel view-adaptive dynamic labeling scheme is developed for efficient query evaluation, in which view specifi...
متن کاملA Fine-Grained Workflow Model with Provenance-Aware Security Views
In this paper we propose a fine-grained workflow model, based on context-free graph grammars, in which the dependency relation between the inputs and outputs of a module is explicitly specified as a bipartite graph. Using this model, we develop an access control mechanism that supports provenance-aware security views. Our security model not only protects sensitive data and modules from unauthor...
متن کاملTransparent Interconnection of Lots of Links (TRILL): Fine-Grained Labeling
The IETF has standardized Transparent Interconnection of Lots of Links (TRILL), a protocol for least-cost transparent frame routing in multi-hop networks with arbitrary topologies and link technologies, using link-state routing and a hop count. The TRILL base protocol standard supports the labeling of TRILL Data packets with up to 4K IDs. However, there are applications that require a larger nu...
متن کاملUltra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
متن کاملFine-Grained Comparisons with Attributes
Given two images, we want to predict which exhibits a particular visual attribute more than the other—even when the two images are quite similar. For example, given two beach scenes, which looks more calm? Given two high-heeled shoes, which is more ornate? Existing relative attribute methods rely on global ranking functions. However, rarely will the visual cues relevant to a comparison be const...
