Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics (2008)
Abat, E., Abbott, B., Abdallah, J., Abdelalim, A. A., Abdesselam, A., ...
A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance...
An Efficient Chaos-Based Feedback Stream cipher (ECBFSC) for Image Cryptosystems (2008)
Hossam El-din, H. Ahmed, Hamdy M. Kalash
Abstract. The chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. Towards this direction, this paper presents an efficient...
Multi-EDA: A Programming Environment for Parallel Computations (2007)
L-e Thorelli, H. Ahmed, V.V. Vlasov, V. V. Vlasov
This report presents the software implementation of the Extended Dataflow Actor model, EDA, using the Parallel Virtual Machine, PVM, system [2]. A formal description of the EDA model can be found in...
Ahmed, H., Ettema, T.J.G., Tjaden, B., Geerling, A.C.M., Siebers, B.
Biochemical studies have suggested that, in hyperthermophilic archaea, the metabolic conversion of glucose via the ED (Entner¿Doudoroff) pathway generally proceeds via a non-phosphorylative variant....

Hossam El-din, H. Ahmed, Hamdy M. Kalash
The chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. Towards this direction, this paper presents an efficient chaosbased...
Crowding-out and crowding-in effects of the components of government expenditure (2000)
This article examines the effects of disaggregated government expenditure on investment using fixed- and random-effect methods. Using the government budget constraint, the analysis explores the...
Evidence for Supercurrent Quantization in Interfacial Josephson Junctions (1997)
Black, M. J., Alphenaar, B. W., Ahmed, H.
We observe a series of discontinuities in the above gap current/voltage characteristics of highly transmissive Nb/Si superconductor/semiconductor interfaces. The bias at which each switch occurs...
Coulomb blockade in silicon based structures at temperatures up to 50 K (1993)
Paul, D. J., Cleaver, J. R. A., Ahmed, H., Whall, Terry E.
Coulomb blockade has been observed in the current-voltage characteristics of structures fabricated in silicon germanium delta-doped material at temperatures up to 50 K. This is consistent with the...
Soum, G., Ahmed, H., Pinna, H., Verdier, P.
La microscopie à balayage, la microanalyse, la physique spatiale ont besoin, d'un point de vue fondamental, de connaître le comportement des électrons dans la matière. Nous présentons dans cet...
HIGHLY CONTROLLED DIFFUSION OF ION IMPLANTED ARSENIC BY MULTIPLE SCAN ELECTRON BEAM HEATING (1983)
Godfrey, D., Mcmahon, R., Ahmed, H., Dowsett, M.
Multiple scan electron beam heating may be used to anneal high dose arsenic implantation damage insilicon. This paper covers the extension of this technique to highly controlled arsenic diffusion...
Davis, J., Mcmahon, R., Ahmed, H.
Advances in the dual electron-beam recrystallisation technique arising from the fast scanning of a line beam parallel to the edges of narrow seeding windows are described. The resultant...
THE ANNEALING BEHAVIOUR OF HIGH DOSE As+ IMPLANTS (1983)
Hasko, D., Mcmahon, R., Ahmed, H.
The annealing behaviour of doses up to 4.1016 ions/cm2 implanted at ion currents up to 10mA is described. Differences between rapid isothermal and furnace annealing in the measured sheet resistances...
