A Competent Approach for Type of Phishing Attack Detection Using Multi-Layer Neural Network

With the enlargement of contemporary technologies and the large-scale global computer networks web-attacks are escalating because of emergent curiosity of people and lawful institutions towards internet. Phishing is one of web-attack carried out by attacker using both social and technical engineering. Generally on web more attacks are launched every month with seek of crafting web addict to consider that they are contacting with a legalized entity for the intention of embezzle identity information, logon records and account details. The phishing attack detection and classification methods are utilized for the prevention and in-depth analysis of the attacks. In this paper, the proposed model has been designed with the multi-directional feature analysis along with the Back-Propagation Probabilistic neural network (BP-PNN) classification. The proposed model has performed better in the terms of the accuracy in all of the domains based upon the attack detection and classification

Bulk Viscosity of Magnetized Neutron Star Matter

We study the effect of magnetic field on the bulk viscosity of nuclear matter in neutron stars. We employ the framework of relativistic mean field theory to observe the dense nuclear matter in neutron stars. The effects are first studied for the case when the magnetic field does not exceed the critical value to confine the electrons to the lowest Landau levels. We then consider the case of intense magnetic field to evaluate viscosity for the URCA processes and show that the inequality $p_{F}(e)+p_{F}(p)\geq p_{F}(n)$ is no longer required to be satisfied for the URCA processes to proceed.Comment: Latex 2e file with four postscripts figure

Lepton flavour violation in The Little Higgs model

Little Higgs models with T-parity have a new source of lepton flavour violation. In this paper we consider the anomalous magnetic moment of the muon \gmtwo and the lepton flavour violating decays \mutoeg and \tautomug in Little Higgs model with T-parity \cite{Goyal:2006vq}. Our results shows that present experimental constraints of \mutoeg is much more useful to constrain the new sources of flavour violation which are present in T-parity models.Comment: LaTeX file with 13 eps figures (included

Harmonic mitigation in an islanded microgrid using a DSTATCOM

The degree of proliferation of Distributed Energy Resources (DERs) and application of power electronics appliances are in demand. A microgrid can contain variety of sources such as diesel generator, wind turbine, PV arrays, micro-turbine and fuel cell. Usually these sources share power where the system frequency changes depending on the power supplied. On the other hand, the microgrid can contain harmonic loads that can affect the performance of the synchronous generators. These deleterious effects of distorting loads can be corrected using a distribution static compensator (DSTATCOM). In this paper, an isochronous control based droop strategy is employed that forces the microgrid to operate at the base frequency of 50 Hz. Therefore the DSTATCOM can be operated at 50 Hz. A closed-loop space vector pulse width modulation (SVPWM) technique is used for the DSTATCOM control. The scheme is validated through the extensive PSCAD/EMTDC simulation studies

Mixed Phase in Compact Starts : M-R relations and radial oscillations

It is believed that quark stars or neutron stars with mixed phase in the core have smaller radii compared to ordinary compact stars. With the recent observation of several low radius objects, typically a radius of $<10 Km.$ for star of mass $< 1M_0$ in low mass X-ray binaries (LMXB), it has become very important to understand the nature of these objects. An accurate determination of mass-radius relationship of these objects provide us with a physical laboratory to study the composition of high density matter and the nature of phase transition. We study the effect of quark and nuclear matter mixed phase on mass radius relationship and radial oscillations of neutron stars. We find that the effect of the mixed phase is to decrease the maximum mass of a stable neutron star and to decrease the radial frequencies .Comment: guest contribution at Int.

Understanding BL Lac objects Structural & kinematic mode changes in the BL Lac object PKS 0735+178

Context. We present evidence that parsec-scale jets in BL Lac objects may be significantly distinct in kinematics from their counterparts in quasars. We argued this previously for the BL lac sources 1803+784 and 0716+714, report here a similar pattern for another well-known BL Lac object, PKS 0735+178, whose nuclear jet is found to exhibit kinematics atypical of quasars. Aims. A detailed study of the jet components' motion reveals that the standard AGN paradigm of apparent superluminal motion does not always describe the kinematics in BL Lac objects. We study 0735+178 here to augment and improve the understanding of the peculiar motions in the jets of BL Lac objects as a class. Methods. We analyzed 15 GHz VLBA (Very Long Baseline Array) observations (2cm/MOJAVE survey) performed at 23 epochs between 1995.27 and 2008.91. Results. We found a drastic structural mode change in the VLBI jet of 0735+178, between 2000.4 and 2001.8 when its twice sharply bent trajectory turned into a linear shape.We further found that this jet had undergone a similar transition sometime between December 1981 and June 1983. A mode change, occurring in the reverse direction (between mid-1992 and mid-1995) has already been reported in the literature. These structural mode changes are found to be reflected in changed kinematical behavior of the nuclear jet, manifested as an apparent superluminal motion and stationarity of the radio knots. In addition, we found the individual mode changes to correlate in time with the maxima in the optical light curve. The last two transitions occurred before a (modest) radio flare. The behavior of this pc-scale jet appears to favor a scenario involving non-ballistic motions of the radio knots, produced by the precession of a continuous jet within the ambient medium.Comment: Accepted for publication in A&A (Abstract reduced for astro-ph
