An Efficient Projector-Based Passivity Test for Descriptor Systems
Abstract--An efficient passivity test based on canonical projector techniques is proposed for descriptor systems (DSs) widely encountered in circuit and system modeling. The test f...

GHM: A generalized Hamiltonian method for passivity test of impedance/admittance descriptor systems
A generalized Hamiltonian method (GHM) is proposed for passivity test of descriptor systems (DSs) which describe impedance or admittance input-output responses. GHM can test passi...

An extension of the generalized Hamiltonian method to S-parameter descriptor systems
Abstract-- A generalized Hamiltonian method (GHM) was recently proposed for the passivity test of hybrid descriptor systems [1]. This paper extends the GHM theory to its S-paramete...

Passive online rogue access point detection using sequential hypothesis testing with TCP ACK-pairs
Rogue (unauthorized) wireless access points pose serious security threats to local networks. In this paper, we propose two online algorithms to detect rogue access points using se...
