A low-profile wideband tri-polarized multi-input multi-output (MIMO) antenna is proposed in this communication. Based on characteristic mode analysis (CMA) of a circular patch, four slots are etched symmetrically the patch to transform high-order monopole-like modes into broadside with lower resonant frequencies. Four sets shorting pins also applied simultaneously adjust frequencies and fundame...

This paper is concerned with nonlinear model order reduction for electro-mechanical systems described by port-Hamiltonian formulae. A novel weighted balacend realization and model order reduction procedure is proposed which preserves port-Hamiltonian structure as well as stability, reachability and observability of the original system. This implies that one can utilize the intrinsic physical pr...

We calculate the response of an ideal Michelson interferometer incorporating both dual recycling and squeezed light to gravitational waves. The photon counting noise has contributions from the light which is sent in through the input ports as well as the vacuum modes at sideband frequencies generated by the gravitational waves. The minimum detectable gravity wave amplitude depends on the freque...

Wired and wireless networks are being attacked and hacked on continuous basis. One of the critical pieces of information the attacker needs to know is the open ports on the victim’s machine, thus the attacker does what is called port scanning. Port scanning is considered one of the dangerous attacks that intrusion detection tries to detect. Snort, a famous network intrusion detection system (NI...

Internet traffic classification has a critical role on network monitoring, quality of service, intrusion detection, network security and trend analysis. The conventional port-based method is ineffective due to dynamic port usage and masquerading techniques. Besides, payloadbased method suffers from heavy load and encryption. Due to these facts, machine learning based statistical approaches have...

The mechanism of providing machine descriptions to the GCC framework has been quite successful as demonstrated by a wide variety of the targets for which a GCC port exists. However, this mechanism is quite ad hoc and the machine descriptions are difficult to construct, understand, maintain, and enhance because of the verbosity, the amount of details, and the repetitiveness. The publicly availab...

A technique of decoupling dielectric stubs (DDS) is proposed for mutual coupling reduction wideband, dual-polarized, and large-scale antenna arrays in this paper, where a low constant DDS mounting on dual-polarized wideband array seamlessly. The mechanism the qualitatively explained. By properly optimizing dimensions stubs, can reduce couplings between elements efficiently. are considered as pe...

This paper focuses on the stabilization of port-controlled Hamiltonian systems employing possibly time-varying controllers. At first we refer to the generalized canonical transformation which preserves the structure of Hamiltonian systems and the passivity property that physical systems innately possess. Next we show a general stabilization strategy for port-controlled Hamiltonian systems based...
