A stochastic competition system with harvesting and distributed delay is investigated, which described by differential equations delay. The existence uniqueness of a global positive solution are proved via Lyapunov functions, an ergodic method used to obtain that the asymptotically stable in distribution. By using comparison theorem limit superior theory, sufficient conditions for persistence m...

the performance of dual-layer multiple tuned mass dampers (dl-mtmd) with uniformly distributed natural frequencies is investigated. the dl-mtmd consists of one large tuned mass damper (l-tmd) and an arbitrary number of small tuned mass dampers (s-tmd). the primary structure is represented as a single degree-of-freedom system which corresponds to a specific vibration mode to be controlled in a r...

Monitoring services are essential for advanced, reliable NoC systems. They should support traffic management, system reconfiguration and fault detection to enable optimal performance and reliability of the system. The paper presents a thorough description of NoC monitoring structures and studies earlier works. A distributed monitoring structure is proposed and compared against the structures pr...

In this paper we present a data structure for searching in multi-dimensional point sets in distributed environments and discuss its experimental evaluation also through a comparison with previous proposals. The data structure is based on an extension of k-d trees. The technological reference context is a distributed environment where multicast (i.e., restricted broadcast) is allowed, but it is ...
