Research ArticleOpen accessIn the abstractSeparation of the Control Plane and Forwarding Plane in Next-Generation RoutersRachid N. Takourout, Samuel Pierre, Laurent MarchandEver since the Internet appeared, network elements, such as routers, have been enhanced with much functionality. They tend to increasingly integrate more services, such as support and security mechanisms, which ensure Quality of Service. Similarly, processor performance continues to increase rapidly. Thus, these two types of evolution trigger the concept of separating the Control plane and the Forwarding plane in … …Journal of Computer Science, Vol. 2, Issue 11 · 30 Nov 2006 · 6,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Mechanisms for Altered Glucose Homeostasis in HIV InfectionPaula W. HruzA complete understanding of the molecular mechanisms leading to HIV-associated insulin resistance remains elusive. Complex interrelationships between genetic predisposition, disease-related body changes and multidrug therapy all contribute to alterations in glucose homeostasis. These abnormalities can be differentiated between acute and reversible changes directly induced by HAART medications and more chronic and less reversible changes due to the development of lipodystrophy … …American Journal of Infectious Diseases, Vol. 2, Issue 3 · 30 Sep 2006 · 6,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeciation of Chromium in Bottom Ash Obtained by the Incineration of the Leather Waste ShavingsK. louhab, H. AkssasThe evolution of bottom ash morphology and chromium metals behavior during incineration of a leather waste shavings at different incineration temperature have been studied. The Cr, Ca, Mg, Cl rates in bottom ashes, flay ashes and emitted gases in different incineration temperature of the tannery wastes are also determined. The morphology of the bottom ashes obtained by incineration at different … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,490 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Postgenomic Era: Transcriptomic as the New Paradigm of LifeBruno Giardina, Marcella Renis, Vito Latora, Salvatore MusumeciNow that complete genome sequences are available for a variety of organism, the elucidation of single gene function involved in the metabolism, includes necessarily a better understanding of the cellular responses on all levels of gene products, mRNA, proteins and metabolites. Such knowledge’s growth is essential since the observable properties of living organisms, so called phenotypes, are the results of … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of the Vertical Dispersion of Pollutants Resulting From Chimneys by Thermosiphon EffectA. O.M. Mahmoud, J. Zinoubi, R. B. Maad, A. BelghithThe dispersion of pollutants, resulting from industrial chimneys, in the surrounding atmosphere made the interest in realizing emitting conditions appears. It also encourages the vertical dispersion of these pollutants. At a given wind velocity, the height of this dispersion is essentially a function of the thermal power and the flow rate at the chimney exit. To improve these qualities, we … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractJBOOM: Java Based Object Oriented Model of Software Configuration ManagementBhavya Mehta, S. K. MuttooMost of the present Software Configuration Management systems deal with version and configurations in the form of files and directories, the need today is to have a Software Configuration Management system that handles versions and configurations directly in terms of functions (program module). A major objective of this research is the use of Java in the Software Configuration Management systems. … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvival in the Current Healthcare Environment How Close Are We to Socialized Medicine?Eldo E. FrezzaIn the 1980's, some hospitals established internal agencies to regulate cash flow and capital expense. State agencies promoted the evolution of healthcare facilities into more business-like organizations. Attention to the following matters will reduce hospital costs: 1) prevent or reduce nosocomial infections; 2) treat diseases at a stage amenable to outpatient therapy; 3) obtain complete information about the policies of … …Journal of Social Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 6,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractLinear Smoothing of Noisy Spatial Temporal SeriesValter Di Giacinto, Ian dryden, Luigi ippoliti, Luca RomagnoliThe main objective of the study is the development of a linear filter to extract the signal from a spatio-temporal series affected by measurement error. We assume that the evolution of the unobservable signal can be modelled by a space time autoregressive process. In its vectorial form, the model admits a state space representation allowing the direct application of the … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,314 accessesView PDFCite
Research ArticleOpen accessIn the abstractFailure Diagnosis on Discrete Event SystemsSihem Kechida, Nasr Eddine DebbacheThe modern technology advances to a point where it is possible and extensively desirable to improve reliability and the technical process safety. This is achieved by computer implanted FDI procedures (Fault Detection and Isolation). However, the malfunction of actuators, sensors and of the process components, as well as erroneous actions of human operators can have some disastrous consequences in high … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Absorption Coefficients and Thermal Diffusivity of Modulated Doped GaAlAs/GaAs Heterostructure by Photothermal Deflection SpectroscopyS. Aloulou, M. Fathallah, M. Oueslati, A. SfaxiWe report in this study theoretical and experimental studies of photothermal deflection spectroscopy (PDS) for planar doped heterostructures AlGaAs/GaAs. The PDS spectra at T=300K are recorded by varying the wavelength of the excited radiation for different modulation frequencies. They show two different regions related to the fundamental electronic transitions from GaAs and Si doped AlGaAs. The DX levels have been … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,264 accessesView PDFCite
