In 2013, Tsai et al. cryptanalyzed Yeh et al. scheme and shown that Yeh et al., scheme is vulnerable to various cryptographic attacks and proposed an improved scheme. In this poster we will show that Tsai et al., scheme is also vulnerable to undetectable online password guessing attack, on success of the attack, the adversary can perform all major cryptographic attacks. As apart of our contribu...

We observe nonequilibrium dynamical magnetic behavior in the magnetically ordered phase of a Tsai-type Tb-Au-Si quasicrystal approximant system. The texture is found to exhibit scalar spin chirality (SSC) order, inferring that SSC order parameter present further find introduction ``pseudo-Tsai'' clusters, associated with additional Tb atoms structure, induces spin-glass dynamics. discuss observ...

Introduction Peer assessment is utilized extensively in digital learning, and many studies have examined the positive influences of online peer assessment on learning (eg, Tseng & Tsai, 2007). However, other studies indicate that this type of activity has negative influences. For example, students may question the fairness of an assessment or disagree with others’ assessments (eg, Kaufman & Sch...

This present research aims to predict the mechanical behavior of composite and hybrid composites based on a polypropylene matrix (PP) reinforced by organic/inorganic naturally occurring fillers using analytical numerical models. It also demonstrate effect hybridization global stiffness material. In this study, Voigt-Reuss models, Halpin-Tsai equations, Hirsch model, simulation are applied effec...

This paper is concerned with the extractions of electromagnetic characteristic modes (CMs) for lossless dielectric bodies, which spurious are prone to generate using traditional definition CMs based on Poggio–Miller–Chang–Harrington–Wu–Tsai (PMCHWT) equations. It found that impedance matrix PMCHWT equations cannot distinguish (i) domain body and background (ii) from excitation source was applie...

The effect of the clusterization on effective properties a composite material reinforced by MXene or graphene platelets is studied using finite element method with periodic representative volume (RVE). A hybrid 2D/3D mesh used to reduce computational complexity numerical model. Several realizations an RVE were generated increasing fractions inclusions, resulting in progressive platelets. Numeri...
