Characterizing Planar Graphs (2009)
Gudkov, Vladimir, Nussinov, Shmuel, Nussinov, Zohar
Cataloging planar diagrams using the depth concept is proposed.
Vladimir Gudkov, Vladimir Montealegre, J. L. Sidoran
Results of the current study of the hypothesis that generalized mutual entropies (mutual Rényi entropies) can provide essential information about network dynamics 1,2 are reported. Based on...
Multidimensional Network Monitoring for Intrusion Detection (2008)
Vladimir Gudkov, Joseph E. Johnson
An approach for real-time network monitoring in terms of numerical timedependant functions of protocol parameters is suggested. Applying complex systems theory for information flow analysis of...
Greene, Geoffrey L., Gudkov, Vladimir
In recent years, an energetic experimental program has set quite stringent limits on a possible "non - 1/r^2" dependence on gravity at short length scales. This effort has been largely driven by the...
Scattering of Ultra Cold Neutrons on Nano-size Bubbles (2006)
Inelastic scattering of ultra cold neutrons on bubbles with the size of nanometers is considered. It is shown that neutron-bubble cross section is large and sensitive to different vibration modes of...
New generation of neutron decay experiments (2004)
New generation of neutron decay experiments, which can be done with high accuracy at new Spallation Neutron Sources, are very important for solution of current problems of fundamental physics and for...
New Enhanced Tunneling in Nuclear Processes (2003)
Ivlev, Boris, Gudkov, Vladimir
The small sub-barrier tunneling probability of nuclear processes can be dramatically enhanced by collision with incident charged particles. Semiclassical methods of theory of complex trajectories...
A Novel Approach Applied to the Largest Clique Problem (2002)
Gudkov, Vladimir, Nussinov, Shmuel, Nussinov, Zohar
A novel approach to complex problems has been previously applied to graph classification and the graph equivalence problem. Here we apply it to the NP complete problem of finding the largest perfect...
Approaches to Network Classification (2002)
Gudkov, Vladimir, Johnson, Joseph E., Nussinov, Shmuel
We introduce a novel approach to description of networks/graphs. It is based on an analogue physical model which is dynamically evolved. This evolution depends on the connectivity matrix and readily...
Graph equivalence and characterization via a continuous evolution of a physical analog (2002)
Gudkov, Vladimir, Nussinov, Shmuel
A general novel approach mapping discrete, combinatorial, graph-theoretic problems onto ``physical'' models - namely $n$ simplexes in $n-1$ dimensions - is applied to the graph equivalence problem....
Multidimensional Network Monitoring for Intrusion Detection (2002)
Gudkov, Vladimir, Johnson, Joseph E.
An approach for real-time network monitoring in terms of numerical time-dependant functions of protocol parameters is suggested. Applying complex systems theory for information f{l}ow analysis of...
New approach for network monitoring and intrusion detection (2001)
Gudkov, Vladimir, Johnson, Joseph E.
The approach for a network behavior description in terms of numerical time-dependant functions of the protocol parameters is suggested. This provides a basis for application of methods of...
Network as a Complex System: Information Flow Analysis (2001)
Gudkov, Vladimir, Johnson, Joseph E.
A new approach for the analysis of information flow on a network is suggested using protocol parameters encapsulated in the package headers as functions of time. The minimal number of independent...
Symmetry Violation in Heavy Nuclei (2000)
The advantage of searching for violation of Time Reversal Invariance in neutron induced reactions using relative measurements of Time and Parity violating effects is discussed. This approach gives...
Johnson, Joseph E., Gudkov, Vladimir
The problem is addressed of developing a very general mathematical foundation for networks that permits practical application in the monitoring of large networks such as the internet for both known...
Monitoring of Network Topology Dynamics (1998)
Gudkov, Vladimir, Johnson, Joseph E., Madamanchi, Rajesh, Sidoran, James L.
We present software for deriving innovative metrics describing dominant parts of the internal structure of large networks. The algorithm is sufficiently fast for the network metrics to support real...
