Feature subset selection in keystroke dynamics using ant colony optimization

  The need to secure sensitive data and computer systems from intruders, while allowing ease of access for authenticated users is one of the main problems in computer security. Traditionally, passwords have been the usual method for controlling access to computer systems but this approach has many inherent flaws. Keystroke Dynamics is a relatively new method of biometric identification and provides a...

Study of the thermal and spectral sensitivities of organic-inorganic fabrication materials based arrayed waveguide grating for passive optical network applications

  In the present paper, the study of the spectral and thermal sensitivities of the inorganic materials such as (Silica-doped, Lithium Niobate) materials and organic materials such as (PMMA Polymer) based waveguides employed in arrayed waveguide grating (AWG) in Passive Optical Networks (PONs) against spectral wavelength and ambient temperature variations. Moreover, we have investigated the best performance...

Design of minimum error digital down-converter (DDC) for GSM mask requirements

  In this paper we present a new design of 2 FIR filters for use on a digital down-converter (DDC) to be used to downconvert a GSM signal. The hardware to work with is a Graychip 4016 multi-standard quad DDC chip (Graychip, Inc2001). The design of FIR filters using windows methods leads to good performance filters, however, sometimes there is a need to design a FIR filter that does not only perform well...
