  • Artail H.A. (AMSTERDAMPO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2004)
    Web personalization and customization are increasingly becoming important services for web users. The conventional approaches used in implementing these services often lead to poor responsiveness, lengthy network delays, ...
  • Kabalan K.Y.; El-Hajj A.; Al-Husseini M. (WASHINGTON2000 FLORIDA AVE NW, WASHINGTON, DC 20009 USA, 2004)
    In this paper, we introduce a new class of planar arrays that we call the Bessel planar arrays. A formula for the current distribution in the elements of these arrays is presented, which is related to Bessel functions. For ...
  • Kayssi A.; El-Haj-Mahmoud A. (, 2004)
    New protocols and network applications must be extensively tested before deployment on the Internet. In this paper, we describe the design and implementation of EmuNET, a lightweight, portable, configurable, and extendable ...
  • Mansour M.M.; Mansour M.M.; Mehrotra A. (, 2004)
    New analytical techniques for estimating the large-signal periodic steady-state solution of MOS LC-tank oscillators using short-channel device equations are presented. These techniques allow us to make quantitative estimates ...
  • Bdeir A.; Abou-Faycal I.; Medard M. (, 2004)
    In communication over time-varying Rayleigh fading channels, adaptive coded modulation for Pilot Symbol Assisted Modulation (PSAM) without feedback has been shown to yield significant benefits in terms of achievable rates. ...
  • Aaraj N.; Nazer A.; Chehab A.; Kayssi A. (LOS ALAMITOS10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA, 2004)
    We propose methods for testing dynamic CMOS circuits using the transient power supply current, iDDT. The methods are based on setting the primary inputs of the circuit under test, switching the clock signal and monitoring ...
  • Bazzi L.; Richardson T.J.; Urbanke R.L. (PISCATAWAY445 HOES LANE, PISCATAWAY, NJ 08855 USA, 2004)
    We show that for the case of the binary-symmetric channel and Gallager's decoding algorithm A the threshold can, in many cases, be determined analytically. More precisely, we show that the threshold is always upper-bounded ...
  • Artail H.A.; Al-Asadi H.; Koleilat W.; Chehab A. (DUBLINDUBLIN INST TECHNOLOGY, BOLTON ST, DUBLIN, IRELAND, 2004)
    The relatively new Wavelet transform and Wavelet-based algorithms have found applications in virtually all engineering and many scientific disciplines. In this paper we point out their applications in enhancing education ...
  • Chehab A.; El-Hajj A.; Al-Husseini M.; Artail H. (DUBLINDUBLIN INST TECHNOLOGY, BOLTON ST, DUBLIN, IRELAND, 2004)
    Spreadsheets were originally intended for business applications like finance, accounting, and so on. However, the ubiquity and simplicity of spreadsheet programs, in addition to their rich library of built-in functions, ...
  • Diab H.B.; Itani M.A. (CALGARYB6, STE 101, 2509 DIEPPE AVE SW, CALGARY, ALBERTA T3E 7J9, CANADA, 2004)
    This paper presents an emerging reconfigurable hardware that delivers flexible high performance for cryptographic algorithms. MorphoSys, a reconfigurable architecture that sustains implementations that can yield into equally ...
  • El-Hajj A.; Kabalan K.Y.; Al-Husseini M. (, 2004)
    In this paper, a new method for exact calculation of the directivity of Chebyshev and modified Chebyshev arrays is presented. It makes use of Chebyshev polynomials and puts the integral in the denominator of the directivity ...
  • El-Afifi L.; Karaki M.; Korban J.; Al Alaoui M.A. (, 2004)
    In this paper, we propose 'Hands-free Interface', a technology that is intended to replace conventional computer screen pointing devices for the use of the disabled. We describe a real time, non-intrusive, fast and affordable ...
  • Mansour M.M. (, 2004)
    This paper investigates high-performance decoder design for regular and irregular repeat-accumulate (RA) codes of large block length. In order to achieve throughputs and bit-error rate performance that are inline with ...
  • Chehab A.; Kayssi A.; Nazer A.; Makki R. (, 2004)
    We propose in this paper a testing method for CMOS circuits that is insensitive to process variations and leakage levels. This method is based on the transient supply current (iDDT) and on the observation that current ...
  • Song I.; Guedea F.; Karray F.; Dai Y.; El Khalil I. (, 2004)
    Natural language command is very abstract. On the other hand, a mobile robot command should be very specific with actual numbers. Thus natural language processing and robot navigation has a big gap. In our research, we ...
  • Kabalan K.Y.; El-Hajj A.; Elias F. (, 2004)
    The problem of aperture in conducting media has been widely considered in the literature. This problem addresses the case of an electromagnetic wave incident on a structure of conducting material segmenting space into two ...
  • Mansour M.M. (, 2004)
    This paper investigates the design of high-performance decoder architectures for two promising codes - Repeat-Accumulate (RA) and LDPC codes - of large block length, in both regular and irregular forms. It addresses the ...
  • Artail H.A. (OXFORDOXFORD FULFILLMENT CENTRE THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2004)
    In this paper we present a method for password recovery through the employment of multiple Web servers, and which we name Peer-Assisted Carrying Authentication (PACA). The paper starts by highlighting the vulnerabilities ...
  • Diab H.B.; Al-Khalidy M. (CALGARYB6, STE 101, 2509 DIEPPE AVE SW, CALGARY, ALBERTA T3E 7J9, CANADA, 2004)
    Research in reconfigurable computing is becoming more pronounced with the increasing research effort being invested in this area. By placing the computationally intense portions of an application onto the reconfigurable ...
  • El-Hajj A.; Kabalan K.Y.; Khoury S. (DUBLINDUBLIN INST TECHNOLOGY, BOLTON ST, DUBLIN, IRELAND, 2004)
    This paper presents an educational spreadsheet programs for calculating the convolution sum of two finite sequences. This convolution sum is accomplished using three different methods. After each method is presented, the ...
