    • Variable cross-correlation code construction for spectral amplitude coding optical CDMA networks 

      Hilal Adnan, Fadhil, Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hassan Y., Ahmed; Hamza Mohammed Ridha, Al-Khafaji (Elsevier Ltd., 2012-06)
      We present, for the first time, several aspects of incoherent optical code-division multiple access (OCDMA) codes, focusing on the flexible variable cross-correlation code allocation and its potential for future optical ...
    • Variable structure system with sliding mode controller 

      Ali Amer, Ahmed; R. Badlishah, Ahmad, Prof. Dr.; Abid, Yahya, Dr.; Hazim Hashim, Tahir; Quinlan, James (Elsevier B.V., 2013)
      This paper describes the application of sliding mode variable structure control (SMVSC) concept for DC motor position control. A mathematical procedure for determining the values of the gains of variable structure system ...
    • "Via-Less” UWB Filter using Patched Microstrip Stubs 

      Mohammad Shahrazel, Razalli; Alyani, Ismail; Mohamed Adzir, Mahdi; Mohd Nizar, Hamidon (VSP (imprint of Brill), 2009)
      This paper presents an Ultra-Wide Band (UWB) microstrip filter which is initially modeled from a quarter-wavelength short-circuited stubs, without the use of any vias. All vias that provide short circuit stubs are replaced ...
    • Wearable dual-band Sierpinski fractal PIFA using conductive fabric 

      Soh, Ping Jack; Vandenbosch, G. A. E.; Ooi, S. L.; Husna, M. R. N. (Institute of Electrical and Electronics Engineers (IEEE), 2011-03-17)
      A novel planar inverted-F antenna (PIFA), incorporating a triangular Sierpinski gasket, is presented. The used conducting textile and polyester fleece allow easy on-body integration and simple practical fabrication. It ...
    • Web-based wireless data acquisition system using 32bit single board computer 

      R. Badlishah, Ahmad; Wan Muhamad Azmi, Mamat; Mohamad Rizon, Mohamed Juhari; Shuhaizar, Daud; Arshad, N.W. (Institute of Electrical and Electronics Engineering (IEEE), 2008)
      The design and architecture of a web-based wireless data acquisition system are presented. This system provides a web interface for remote monitoring of sensors deployed which connected using wireless technology. The design ...
    • X-band trisection substrate-integrated waveguide quasi-elliptic filter 

      Alyani, Ismail; Mohammad Shahrazel, Razalli; Mohamed Adzir, Mahdi; Abdullah, R.S.A.R; Noordin, N.K; Rasid, M.F.A (EMW Publishing, 2008)
      A narrowband trisection substrate-integrated waveguide elliptic filter with coplanar waveguide (CPW) input and output ports is proposed and demonstrated for X-band applications. The filter is formed by incorporating ...
