A survey on the development of Isl amic higher education in Ind onesia: an epistemol ogical review
Saadi
Indonesian Journal of Islam and Muslim Societies , 2011,
Abstract: Social changes, development and advancement of humans’ culture influence education as inseparable aspect of human life. In line with Islamic higher education many thinkers proposed their ideas of how to formulate its appropriate epistemological background in different views. There are some notable persons for this field, such as Iqbal, F azlur Rahman, Afzalur Rahman, Al-Faruqi which to some extent parallel or influence Indonesian thinkers’ such as Mukti Ali, Harun Nasution, Cak Nur , Amin Abdullah, etc. Some are still at the level of speculative thought, while others have applied their ideas in educational institutions, like Amin Abdullah and Imam Suprayoga.
L-Error Estimate of Schwarz Algorithm for Noncoercive Variational Inequalities  [PDF]
Samira Saadi, Allaoua Mehri
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.53054
Abstract:

The Schwarz method for a class of elliptic variational inequalities with noncoercive operator was studied in this work. The author proved the error estimate in L∞-norm for two domains with overlapping nonmatching grids using the geometrical convergence of solutions and the uniform convergence of subsolutions.

Overlapping Nonmatching Grid Method for the Ergodic Control Quasi Variational Inequalities  [PDF]
H. Mécheri, S. Saadi
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.31A005
Abstract: In this paper, we provide a maximum norm analysis of an overlapping Schwarz method on nonmatching grids for a quasi-variational inequalities related to ergodic control problems studied by M. Boulbrachene [1], where the “discount factor” (i.e., the zero order term) is set to 0, we use an overlapping Schwarz method on nonmatching grid which consists in decomposing the domain in two sub domains, where the discrete alternating Schwarz sequences in sub domains converge to the solution of the ergodic control IQV for the zero order term. For \"\" and under a discrete maximum principle we show that the discretization on each sub domain converges quasi-optimally in the norm \"\" to 0.
Autoconfiguration Algorithm for a Multiple Interfaces Adhoc Network Running OLSR Routing Protocol
Saadi Boudjit
International Journal of Computer Networks & Communications , 2013,
Abstract: Network configuration is the assignment of network parameters necessary for a device to integrate the network, examples being: an IP address, netmask, the IP address of the gateway, etc ... In the case of Mobile Ad hoc NETworks (MANETs), the connectivity of nodes is highly dynamic and a central administration or configuration by the user is very difficult. This paper presents an autoconfiguration solution for ad hoc networks running the widely implemented version of OLSR routing protocol, the 2003 RFC 3626 [1]. This solution is based on an efficient Duplicate Address Detection (DAD) algorithm, which takes advantage of the genuine optimization of the OLSR routing protocol. The proposed autoconfiguration algorithm is proved to operate correctly in a multiple interfaces OLSR network.
One-Dimensional Hydrodynamic Modelling for River Flood Forecasting
Yusron Saadi
Civil Engineering Dimension , 2008,
Abstract: The ability to forecast maximum water depth during maximum discharge of a design flood is very important in designing flood protection scheme along the river reach. This paper explains the use of ISIS Flow, a one-dimensional hydrodinamic computer modelling for river flood forecasting. The computer simulations produced detailed information from each node including the maximum water depth during maximum discharge, thus it can be expected that an economical flood protection structure can be produced.
Fractional Critical Shear Stress at Incipient Motion in a Bimodal Sediment
Yusron Saadi
Civil Engineering Dimension , 2008,
Abstract: The objective of this research was to examine and to quantify the stability of mixed grain sediment beds previously exposed to different time length of uniform antecedent flow hydrograph. The assessment of bed stability was carried out based on the observation of temporal pattern of eroded sediment during two identical stability tests with time varying flow and higher peak discharge. This was linked to the movement of individual sediment fractions to obtain fractional critical shear stress in a bimodal sediment mixture. The stability tests suggest a considerable increased in the stability of individual grain. Longer exposure time by antecedent flow clearly had an influence in the increasing stability of the bed. The increased rate of fractional critical shear stress during stability tests varied between 16 % and 35 % in the coarse mode whilst in the fine mode the rate of increase varied between 27 % and 39 %.
Some properties of Lipschitz strongly p-summing operators
Khalil Saadi
Mathematics , 2014,
Abstract: We consider the space of molecules endowed with the transpose version of the Chevet-Saphar norm and we identify its dual space with the space of Lipschitz strongly p-summing operators. We also extend some old results to the category of Lipschitz mappings and we give a factorization result of Lipschitz (p,r,s)-summing operators.
On a Voter model on R^d: Cluster growth in the Spatial Lambda-Fleming-Viot Process
Habib Saadi
Mathematics , 2014,
Abstract: The spatial Lambda-Fleming-Viot (SLFV) process (Barton, Etheridge and V\'eber, 2010) can be seen as a generalised Voter Model with configuration space $M^{R^d}$, where M is the set of probability measures on some space K. Such processes are usually studied thanks to a dual process that describes the genealogy of a sample of particles. In this paper, we study the growth of a cluster, and our surprising result is that with probability one, every bounded cluster stops growing in finite time. Because the traditional (backward in time) duality methods fail, we develop an original forward in time approach that exploits a martingale property of the process. To make it feasible, we construct adequate objects that allow to handle the complex geometry of the problem. We are able to prove the result in any dimension $d$.
On the composition ideals of Lipschitz mappings
Khalil Saadi
Mathematics , 2015,
Abstract: We study in this paper some property of Lipschitz mappings which admit factorization through an operator ideal. We try to construct Lipschitz cross-norms from known tensor norms in order to represent certain classes of Lipschitz mappings. Inspired by the definition of p-summing linear operators we introduce a new concpet in the the category of Lipschitz mappings that is called strictly Lipschitz p-summing.
A Spectroscopic Approach to Assess Heavy Metals Contents of the Mine Waste of Jalta and Bougrine in the North of Tunisia  [PDF]
Sonia Gannouni, Noamen Rebai, Saadi Abdeljaoued
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43029
Abstract: Near InfraRed Spectroscopy (NIRS) has become an extremely important analytical technique in recent years and been applied in various geoscience areas such as mineral exploration and environmental studies. It is used for studying the physico-chemical properties of earth materials by enabling the interpretation of mineral composition and the study of its variability based on the diagnostic of spectral features. In this research, the application of laboratory reflectance spectroscopy in assessing heavy metals pollution is investigated. The potential use of reflectance spectroscopy in detecting Fe-related and clay minerals as well as the quantitative characterization of pollutants is studied for the mine waste of Jalta and Bougrine in the North of Tunisia. Mining activities of lead/Zn, have led to extensive pollution. The analysis of geochemical results outlined the level and spatial pattern of pollutants concentration. Results of the study showed that a relationship exists between reflectance spectra and geochemical measures of pollutants. The Spectral interpretation of Fe-related minerals and clay minerals showed that they are related to the pollutants and can be used as indirect spectral indicators of the pollution. The Fe-minerals include: jarosite, goethite, hematite/goethite, and hematite; clay minerals and feature-less (aspectral) materials. A direct quantitative relationship between pollutants and spectral parameters shows that Pb-Zn-Mn are the best correlated with a ratio of 610/500 nm range while Ni-Cr have a best correlation with a slope around 980 nm. Outputs from Partial Least Square Regression (PLSR) confirmed these relationships and also indicated that spectral parameters and reflectance values within 400 - 2500 nm range can better predict the contamination for Mn, Pb and Zn than for Ni and Cr but not for Fe, Cu, Cd, EC and pH.
