    A Novel Fingerprint Re-Alignment Solution That Uses the TFCP as a Reference

    Fingerprint re-alignment is an important aspect in the subject of fingerprint biometrics because a fingerprint recognition system that does not attempt to re-align an involuntarily rotated fingerprint can create opportunities for falsely rejecting a legitimate subject. It can also create opportunities for security attacks where an illegitimate subject voluntarily rotates...

    Signature Modelling and Radiometric Rendering Equations in Infrared Scene Simulation Systems

    The development and optimisation of modern infrared systems necessitates the use of simulation systems to create radiometrically realistic representations (e.g. images) of infrared scenes. Such simulation systems are used in signature prediction, the development of surveillance and missile sensors, signal/image processing algorithm development and aircraft self-protection countermeasure system development and...

    Interference-Aware Power Control for Multi-Radio Multi-Channel Wireless Mesh Networks

    Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in WMNs. In this paper, the authors present a dynamic power control for MRMC WMNs. First, WMN is represented as a set of disjoint Unified Channel Graphs (UCGs). Second, each radio assigned to a unique UCG adjusts the transmission power...
