The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...

Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-Einstein warped product, and non compact complete base manifolds which do not admit any non-triv...

In recent years False Base Stations (FBSs) have received increased attention. A Station can perform active or passive attacks against mobile devices user equipment (UE) to steal private information, such as International Mobile Subscriber Identifier (IMSI), trace users locations, prevent from getting service operators. Most of the existing solutions related FBS focused on detection aspects fals...

A two-step system identification is presented to estimate modal properties of a base-fixed model from ambient vibration records on multi-story building with soil-structure interaction (SSI). In the first step output-only stochastic subspace method employed for estimating SSI. second are modified estimates, by using theoretical relations between multi-degree-of-freedom SSI and its equivalent der...
