Privacy Violation and Detection Using Pattern Mining Techniques

Privacy, its violations and techniques to bypass privacy violation have grabbed the centre-stage of both academia and industry in recent months. Corporations worldwide have become conscious of the implications of privacy violation and its impact on them and to other stakeholders. Moreover, nations across the world are coming out with privacy protecting legislations to prevent data privacy violations. Such legislations however expose organizations to the issues of intentional or unintentional violation of privacy data. A violation by either malicious external hackers or by internal employees can expose the organizations to costly litigations. In this paper, we propose PRIVDAM; a data mining based intelligent architecture of a Privacy Violation Detection and Monitoring system whose purpose is to detect possible privacy violations and to prevent them in the future. Experimental evaluations show that our approach is scalable and robust and that it can detect privacy violations or chances of violations quite accurately.

Application of Replacement Theory in Determination of Pavement Design Life

This paper presents a methodology to determine the economic life of pavement based replacement theory/decision. The replacement theory is generally used for the determination of the replacement period of machines, bulbs, vehicles, equipment, buildings, T.V. parts… etc. This theory has been used to determine the economic life pavement for a road project and a bridge project with a real case study. The economic life has been found out. The economic life of flexible pavement has been found to be 15 years for national highways. This theory can be also applied to determine the economic life of new developed items/useful materials for highway projects

A new Tolman test of a cosmic distance duality relation at 21 cm

Under certain general conditions in an expanding universe, the luminosity distance (d_L) and angular diameter distance (d_A) are connected by the Etherington relation as d_L = d_A (1 + z)^2. The Tolman test suggests the use of objects of known surface brightness, to test this relation. In this letter, we propose the use of redshifted 21 cm signal from disk galaxies, where neutral hydrogen (HI) masses are seen to be almost linearly correlated with surface area, to conduct a new Tolman test. We construct simulated catalogs of galaxies, with the observed size-luminosity relation and realistic redshift evolution of HI mass functions, likely to be detected with the planned Square Kilometer Array (SKA). We demonstrate that these observations may soon provide the best implementation of the Tolman test to detect any violation of the Etherington relation.Comment: 4 pages, 2 figures, 1 table, v2: published versio

Characteristics of propagation of small-amplitude waves in a cold plasma, assumed to be fluid-like, compressible, and a mixture of populations of weakly bound electrons, free electrons and ions, is studied. For an elliptically polarized wave, we have evaluated (i) the zeroth-harmonic magnetic moment, (ii) the damping factor and cut-off frequency and (iii) the collisional energy absorption. The relative roles of the frequency (ω0) of the bound electrons, the characteristic frequency of free electrons (ωf), the characteristic frequency of bound electrons (ωb) and the resonance condition, where ω0 equals the wave frequency ω, and the effects of the cut-off frequency, is studied. The cut-off frequency has a higher value; in the resonance case (ω 2 = ω 2 0 ) it increases when ω0 is greater than ωf , and decreases when ω0 is less than ωf . The field of magnetic-moment at this resonance is enhanced when ω0 is large compared to ωf . The exchange of energy between the wave field and the constituents of this plasma is considered.Proučavamo značajke širenja valova male amplitude u hladnoj plazmi za koju pretpostavljamo da je fluidna, stišljiva i smjesa slabo vezanih i slobodnih elektrona te iona. Za eliptički polarizirane valove izveli smo (i) magnetski moment prvog harmonika, (ii) faktor gušenja i graničnu frekvenciju i (iii) sudarnu apsorpciju energije. Istražujemo relativnu ulogu frekvencije vezanih elektrona (ω0), karakteristične frekvencije slobodnih elektrona (ωf), karakteristične frekvencije vezanih elektrona (ωb) i rezonantnog uvjeta kada je ω0 jednako frekvenciji valova ω te učinaka granične frekvencije. Granična je frekvencija viša u slučaju rezonancije (ω 2 = ω 2 0 ), ona raste ako je ω0 manji od ωf , a smanjuje se ako je ω0 veći od ωf . Magnetski moment polja je na rezonanciji povećan ako je ω0 veći od ωf . Razmatramo i izmjenu energije između valnog polja i sastavnica plazme

Reheating furnace's soaking zone hearth refractories - a rational approach

The technology of steel processing subsequent to ingot casting, follows heating in soaking pit and rolling to form blooms, billets etc. Further reduction is carried out through heating and rolling to yield the final usable products. Reheating furnaces are used in reheating the "Semis" before they are used in secondary-processing

Raman anomalies as signatures of pressure induced electronic topological and structural transitions in black phosphorus: Experiments and Theory

We report high pressure Raman experiments of Black phosphorus up to 24 GPa. The line widths of first order Raman modes A$^1_g$, B$_{2g}$ and A$^2_g$ of the orthorhombic phase show a minimum at 1.1 GPa. Our first-principles density functional analysis reveals that this is associated with the anomalies in electron-phonon coupling at the semiconductor to topological insulator transition through inversion of valence and conduction bands marking a change from trivial to nontrivial electronic topology. The frequencies of B$_{2g}$ and A$^2_g$ modes become anomalous in the rhombohedral phase at 7.4 GPa, and new modes appearing in the rhombohedral phase show anomalous softening with pressure. This is shown to originate from unusual structural evolution of black phosphorous with pressure, based on first-principles theoretical analysis.Comment: 13pages, 12figure
