Online Mode Switch Algorithms for Maintaining Data Freshness in Dynamic Cyber Physical Systems

Online Mode Switch Algorithms for Maintaining Data Freshness in Dynamic Cyber Physical Systems Abstract Maintaining the freshness of real-time data is one of the crucial design issues in cyber-physicalsystems (CPS). Past studies have focused on designing update algorithms to minimize the workload imposed by a fixed set of update tasks while ensuring the temporal validity of data. In this paper, we revisit this problem in dynamic cyber-physical systems (DCPS) […]


Nearest Keyword Set Search in Multi-Dimensional Datasets

Nearest Keyword Set Search in Multi-Dimensional Datasets Abstract Keyword-based search in text-rich multi-dimensional datasets facilitates many novel applications and tools. In this paper, we consider objects that are tagged with keywords and are embedded in a vector space. For these datasets, we study queries that ask for the tightest groups of points satisfying a givenset of keywords. We propose a novel method […]
