The development of cloud computing and distributed technologies has shifted log management operations to an aggregated form. Diverse information devices as well systems perform data collection status analysis through a unified aggregation system. However, with the increasingly diverse business forms, threats confronted by are also mounting, among which leakage, tampering, loss, security vulnera...

reservoir permeability is a critical parameter for characterization of the hydrocarbon reservoirs. in fact, determination of permeability is a crucial task in reserve estimation, production and development. traditional methods for permeability prediction are well log and core data analysis which are very expensive and time-consuming. well log data is an alternative approach for prediction of pe...

Abstract We review the space complexity of deterministically exploring undirected graphs. assume that vertices are indistinguishable and edges have a locally unique color guides traversal space-constrained agent. The graph is considered to be explored once agent has visited all vertices. visit results for this setting showing $$\varTheta \,(\log n)$$ <mml:math xmlns:mml="http://www.w3.org/1998/...

We consider exploration problems where a robot has to construct a complete map of an unknown environment. We assume that the environment is modeled by a directed, strongly connected graph. The robot’s task is to visit all nodes and edges of the graph using the minimum number R of edge traversals.
