Removing an Incidence from a Formal Context
نویسندگان
چکیده
We analyze changes in the structure of a concept lattice corresponding to a context resulting from a given context with a known concept lattice by removing exactly one incidence. We identify the set of concepts affected by the removal and show how they can be used for computing concepts in the new concept lattice. We present algorithms for incremental computation of the new concept lattice, with or without structural information.

How Does Explicit and Implicit Instruction of Formal Meta-discourse Markers Affect Learners’ Oral Proficiency?
Meta-discourse markers are an inevitable part of oral proficiency which improve both the quality and comprehension of learners’ speech. While studies of oral meta-discourse have been conducted since the 1980s in a European or US context, they have remained relatively untouched in Iran. Therefore, this study aimed to seek the impact of both explicit and implicit teaching of formal meta-discourse...
متن کاملCliques Role in Organizational Reputational Influence: A Social Network Analysis
Empirical support for the assumption that cliques are major determinants of reputational influence derives largely from the frequent finding that organizations which claimed that their cliques’ connections are influential had an increased likelihood of becoming influential themselves. It is suggested that the strong and consistent connection in cliques is at least partially responsible for the ...
متن کاملA context-sensitive dynamic role-based access control model for pervasive computing environments
Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...
متن کاملInvestigating the effect of Biodrof systems based on algae-bacterial biofilm for removing total Nitrogen, Phosphorus from domestic wastewater
Due to an increase of the human population on Earth, log of pollutants to water resources has increased and this caused the more restriction of water resources for human. Limited availability of fresh water resources, especially in the Middle East that have arid and semi-arid climate increases the importance of water recycling. The main problem in many conventional wastewater treatment systems ...
متن کاملCAMAC: a context-aware mandatory access control model
Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...
