  • Elbehiery, H. M.; Hefnawy, A. A.; Elewa, M. T. (ICGST-GVIP Journal, 2005)
    This paper deals with the visual inspection of ceramic’s tiles surfaces for the purpose of detecting flaws using a wavelet approach. Surface defects in the ceramic tiles are viewed as in-homogeneities in regularity ...
  • Elbehiery, H.M.; Hefnawy, A.A.; Elewa, M.T. (IEEE, 2011)
    Quality control in ceramic tile manufacturing is hard, labor intensive and it is performed in a harsh industrial environment with noise, extreme temperature and humidity. It can be divided into color analysis, dimension ...
  • El-Kameesy, S.U.; Abdel-Wahab, M.S.; El-Faramawy, N. (Applied Radiation and Isotopes, 1992)
    A study of the background gamma radiation spectrum in Ain Shams University buildings was performed for the energy range 50 keV–3 MeV using a hyperpure Ge-detector. The absolute dose for each gamma line was calculated and ...
  • El-Kameesy, S. U.; Abdel-Wahab, M. S.; Al-Houty, L.; Abou-Leila, H. (Acta Physica Hungarica, 1992)
    The decay of154Eu to154Gd has been studied using H. P. Ge and H. P. Ge−NaI(Tl) spectrometers in coincidence measurements. 141 gamma transitions have been observed. One of these transitions is found to be new and has an ...
  • Fouad, Khaled M.; Nofal, Mostafa A.; Harb, Hany M.; Nagdy, Nagdy M. (International Journal of Advanced Computer Science and Applications, 2011)
    In the learning environments, users would be helpless without the assistance of powerful searching and browsing tools to find their way. Web-based e-learning systems are normally used by a wide variety of learners with ...
  • Ibrahim, Nora Y.; Mokhtar, Sahar A.; Harb, Hany M. (International Journal of Computer Science and Information Security,, 2010)
    This Ontologies are widely used as a means for solving the information heterogeneity problems on the web because of their capability to provide explicit meaning to the information. They become an efficient tool for ...
  • Harb, Hany; Kelash, Hamdy; Shehata, Ahmed (2002)
    We introduce a method for rule termination analysis within active databases by using evolution graphs which simulating rule processing statically and considering both rule activation and deactivation. The evolution graph ...
  • Abdel-Wahab, M. S.; Eissa, H. M.; El Enany, N.; El Fiki, S.; El-Adl, E. H.; El-Feky, M. A. (Nuclear Tracks And Radiation Measurements, 2008)
    • Track etch rate characteristics of CR-39 plastic detector exposed to 28Si ions of 670 MeV energy have been investigated. Experimental results were obtained in terms of frequency distribution of the track diameter, track ...

  • Abdel-Wahab, M.S.; El-Enany, N.; Sharaf, M.A.; El-Fiki, S.; El-Feky, M.A. (1991)
    Neutron depth dose distribution in a water phantom for some plastics was measured. The experiment was made with Makrofol, CR-39 and LR-II5. The fluence distribution of 252Cf in air and in water phantom were investigated. ...
  • Harb, Hany M.; Zaghrot, Afaf A.; Gomaa, Mohamed A.; Desuky, Abeer S. (Research India Publications, 2011)
    The network traffic data provided for the design of intrusion detection are always large with ineffective information and high-dimensional feature vectors. This often imposes a high computational cost as well as the risk ...
  • Abdel-Wahab, M. S.; Eissa, H. M.; El-Adl, E. H.
    The alpha particle response which is characteristic of polycarbonate detectors CR-39 has been investigated. The track diameter as a function of alpha energy in the range from 5.1–22.2 MeV was examined. The mean track ...
