The literature on chaos theory reports numerous Neural Networks (NNs) in which the individual neurons have been interconnected and designed so that the overall network yields chaotic behaviour. Although such Chaotic Neuron Net-works(CNNs) have been extensively studied, the results concerning CNNs which can demonstrate chaos, Associative Memory (AM), and Pattern Recognition (PR) are scanty. Recently, the Adachi NN and its variants have been shown to yield the entire spectrum of these properties as its/their parameters change. In this vein, we1 investigate the properties of a specific network of Logistic Neurons (LNs). by appropriately defining the input/output characteristics of a fully connected network of LNs, and by defining their set of weights and output functions, we have succeeded in designing a Logistic Neural Network (LNN) possessing some of these properties. Indeed, by varying the parameters of the LNN, we show that it can yield AM and PR properties for different settings of the parameters. As far as we know, the results presented here novel, and represent the first NN (other than the Adachi NN) which simultaneously exhibits both chaotic, AM and PR properties. © 2010 IEEE.

An updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets and a neutralino, using 5.0 and 22.9 fb−1 of pp collisions at 7 and 8 TeV, respectively. Candidate decay events are triggered in selected empty bunch crossings of the LHC in order to remove pp collision backgrounds. Selections based on jet shape and muon system activity are applied to discriminate signal events from cosmic ray and beam-halo muon backgrounds. In the absence of an excess of events, improved limits are set on gluino, stop, and sbottom masses for different decays, lifetimes, and neutralino masses. With a neutralino of mass 100 GeV, the analysis excludes gluinos with mass below 832 GeV (with an expected lower limit of 731 GeV), for a gluino lifetime between 10 μs and 1000 s in the generic R-hadron model with equal branching ratios for decays to qq¯χ˜0 and gχ˜0. Under the same assumptions for the neutralino mass and squark lifetime, top squarks and bottom squarks in the Regge R-hadron model are excluded with masses below 379 and 344 GeV, respectively.

A search is presented for microscopic black holes in a like-sign dimuon final state in proton–proton collisions at s=8 TeV. The data were collected with the ATLAS detector at the Large Hadron Collider in 2012 and correspond to an integrated luminosity of 20.3 fb−1. Using a high track multiplicity requirement, 0.6±0.2 background events from Standard Model processes are predicted and none observed. This result is interpreted in the context of low-scale gravity models and 95% C.L. lower limits on microscopic black hole masses are set for different model assumptions.

A search is presented for direct chargino production based on a disappearing-track signature using 20.3 fb−1 of proton-proton collisions at s=8 TeV collected with the ATLAS experiment at the LHC. In anomaly-mediated supersymmetry breaking (AMSb) models, the lightest chargino is nearly mass degenerate with the lightest neutralino and its lifetime is long enough to be detected in the tracking detectors by identifying decays that result in tracks with no associated hits in the outer region of the tracking system. Some models with supersymmetry also predict charginos with a significant lifetime. This analysis attains sensitivity for charginos with a lifetime between 0.1 and 10 ns, and significantly surpasses the reach of the LEP experiments. No significant excess above the background expectation is observed for candidate tracks with large transverse momentum, and constraints on chargino properties are obtained. In the AMSb scenarios, a chargino mass below 270 GeV is excluded at 95% confidence level.

A search has been performed for photons originating in the decay of a neutral long-lived particle, exploiting the capabilities of the ATLAS electromagnetic calorimeter to make precise measurements of the flight direction of photons, as well as the calorimeter’s excellent time resolution. The search has been made in the diphoton plus missing transverse energy final state, using the full data sample of 4.8 fb−1 of 7 TeV proton-proton collisions collected in 2011 with the ATLAS detector at the LHC. No excess is observed above the background expected from Standard Model processes. The results are used to set exclusion limits in the context of gauge mediated supersymmetry breaking models, with the lightest neutralino being the next-to-lightest supersymmetric particle and decaying with a lifetime in excess of 0.25 ns into a photon and a gravitino.

International Conference on computer and Communication technology (ICCCT)

作者： Nagaraj V. Dharwadkar b. b. Amberker Supriya Prateeksha b. Panchannavar Computer Science & Engineering National Institute of Technology Warangal Andhra Pradesh India Information Science & Engineering B. L. D. A's College of Engg. & Tech Bijapur Karnatak India

The modern telemedicine often lacks in the infrastructure to deploy image security standards. The fragile watermarking scheme provides good security solution to medical images in telemedicine. In this paper, we present a reversible (distortion free), fragile, spatial domain watermarking scheme for medical images. The medical image authenticity and security can be achieved by two modes of watermarking operations. In the first mode, the watermark (fingerprint) is embedded into host image and later, for copyright justification the watermark (fingerprint) is extracted from host image. In the second mode of the operation the watermark (fingerprint) is extracted from unaltered components of the image ie. stored as the key. Later, this key information is used for recovering the watermark. The proposed scheme uses the second mode of operation which extracts the watermark from the unaltered pixel components of image. The extracted watermark is used for copy-right justification. As medical images have zero tolerance for noise our scheme produces noise free watermarked medical images. The scheme is robust to different types of attacks. The fragility and robustness of the scheme is analyzed considering different types of image processing attacks.

This paper considers problem of stabilization of the first order nonholonomic chained system using polar-like coordinates. A control method considered here can be regarded as an extension of control solution based on polar coordinate transformation in order to apply it to other system than unicycle. Presented control strategy gives possibility to obtain fast convergence of regulation errors without oscillatory behavior. A robustness of the controller in the neighborhood of the desired point is ensured via additional non-smooth techniques. In order to verify usefulness of developed control strategy simulation results are given. © 2009 EUCA.

Wireless sensor networks have emerged as an important application area resulting from the advancement of efficient short-range radio communication and miniaturization of computing devices. Nodes in such a network generally remain in an unattended environment and thereby they are prone to attack by adversaries. Therefore, the need of tolerating such attacks is of utmost importance. Firstly, multilevel tier architecture based on clustering of nodes in each tier is introduced. Then the work develops a scheme for WSN to tolerate such attack and maintains connectivity with negligible delay. This scheme is also capable of tolerating attacks in multiple nodes, provided the nodes are located in some specified positions. The claim has been justified with proof.

In this paper we enhance the PLA relational spatial model for storing a special type of planar graphs. The PLA-model is very handy to store 2-connected planar graphs, but it is not capable at all to store some other important classes of planar graphs: trees and, more generally, planar graphs with cut edges. In this paper we propose a method for their representation. The main idea is based on Halin graphs that are planar graphs of minimum degree 3 from which the removal of the boundary edges of the infinite region yields a tree. Our results are to identify Halin graphs from the model, and to represent trees as virtual Halin graphs in order to store them without major alteration of the original PLA-Model. © 2006 IEEE.
