Critical evedenciarcy analysis of 26/11 attacks with reference to cyber-terrorism

By thorough analysis of Mumbai terrorist attacks of 26/11, it was observed that the attacks were form of Cyber terrorism as it was done to convey particular destructive message to the government, sending of threatening emails, defacing of government websites, hacking and cracking of crucial government systems. 'Protected systems' were compromised and civil amenities were disrupted. Digital information systems computer networks which not only affected governing system but also the population of a target area was affected to create a panic or situation of threat. Computer and digital communication networks were main tools of extremists in this case. Also, Supreme Court judgement on Mumbai Attacks case, in para number 57 specifies about use of Google Earth, tampering with telecommunication networks and digital networking shows that the Attack was done by was done by Hi-Tech offenders. Although electronic eavesdropping often yields valuable data, even tantalizing clues can be missed if the technology is not closely monitored, the intelligence gleaned from it is not linked with other information, or analysis does not sift incriminating activity from the ocean of digital data as traced by Inteligence agencies of US, UK and India during investigation of attacks.</jats:p

Study of crystal structure, dielectric, magnetic and magnetoelecrtic properties of xCoFe2O4-(1-x)Na0.5Bi0.5TiO3 composites

Multiferroic composites of spinel ferrite and ferroelectric xCoFe(2)O(4) - (1-x)Na0.5Bi0.5TiO3 (with x = 0.10,0.30,0.50) were efficiently prepared by standard solid state reaction mechanism. X-ray diffractometer was used to analyze crystal structure of the prepared composites. The observed XRD patterns of the composites comprise peaks of both the phases i.e. ferrite and ferroelectric, with no sign of secondary peaks. Rietveld refinement of XRD data further confirms the coexistence of these two phases with cubic (Fd3m) and rhombohedral (R3c) symmetry corresponding to ferrite and ferroelectric phase respectively. The 3-dimensional overview of crystal structure of pure CoFe2O4 and Na0.5Bi0.5TiO3 and of composite 0.50CoFe(2)O(4) - 0.50Na(0.5)Bi(0.5)TiO(3) is generated by using refined parameters. The dielectric constant (epsilon') and dielectric loss (tan delta) values were recorded as a function of frequency ranging from 100 Hz to 7 MHz and at different temperatures. Both epsilon' and tan delta follow dispersion pattern at lower frequencies while show frequency independent behavior at higher frequencies. The magnetic evaluation carried by analyzing M-H hysteresis loop reveals the ferrimagnetic characteristics of these composites. The highest value of magnetic moment is 1.12 mu(B) observed for composite 0.50CoFe(2)O(4) - 0.50Na(0.5)Bi(0.5)TiO(3). Magnetoelectric (ME) voltage coefficient (alpha) was also demonstrated to observe the interaction between ferrite and ferroelectric phases. The highest value of alpha (72.72 mu V/Oe cm) is obtained for low ferrite composition 0.10CoFe(2)O(4) - 0.90Na(0.5)Bi(0.5)TiO(3), which suggests the dependence of magnetoelectric response on the resistivity of the composites
