We consider a nonlinear parametric Neumann problem driven by the anisotropic $(p,q)$-Laplacian and reaction which exhibits combined effects of singular term superlinear perturbation. are looking for positive solutions. Using combination topological variational tools together with suitable truncation comparison techniques, we prove bifurcation-type result describing set solutions as parameter $\...

In this paper we propose a Ping – Pong transitions on web applications. The numerical values of parameters in real time situations are not exactly predictable; to overcome this we are using a fuzzy criterion through possibilities which are represented as a triangular fuzzy number. We introduce a method to study the long term behavior (steady state) of Ping – Pong transitions using Fuzzy Markov ...

Security of the "ping-pong" quantum communication protocol recently proposed by Boström and Felbinger [Phys. Rev. Lett. 89, 187902 (2002)]] is analyzed in the case of considerable quantum channel losses. The eavesdropping scheme is presented, which reveals that the ping-pong protocol is not secure for transmission efficiencies lower than 60%. Our scheme induces 50% losses, which, however, can b...

We investigate the properties of the B-band Tully-Fisher (T-F) relation for 25 compact group galaxies, using Vmax derived from 2-D velocity maps. Our main result is that the majority of the Hickson Compact Group galaxies lie on the T-F relation. However, about 20% of the galaxies, including the lowest-mass systems, have higher B luminosities for a given mass, or alternatively, a mass which is t...

We present high-resolution mass reconstructions for five massive cluster-lenses spanning a redshift range from z = 0.18–0.57 utilizing archival Hubble Space Telescope (HST) data and applying galaxy-galaxy lensing techniques. These detailed mass models were obtained by combining constraints from the observed strong and weak lensing regimes. Quantifying the local weak distortions in the shear map...

Images are an important part of today's digital world. However, due to the large quantity of data is needed to represent modern imagery; the storage of such data can be expensive. Thus, the work on efficient image storage (image compression) has the potential to reduce storage costs and enable new applications. Block Truncation Coding (BTC) is a lossy image compression technique which uses mome...

The symplectic Wisdom-Holman map revolutionized long-term integrations of planetary systems. There is freedom in such methods of how to split the Hamiltonian and which coordinate system to employ, and several options have been proposed in the literature. These choices lead to different integration errors, which we study analytically and numerically. The WisdomHolman method in Jacobi coordinates...

One desirable application of Bidirectional Forwarding Detection (BFD) is to detect a Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) data plane failure. LSP Ping is an existing mechanism for detecting MPLS data plane failures and for verifying the MPLS LSP data plane against the control plane. BFD can be used for the former, but not for the latter. However, the control plane proc...
