Abstract:
In recent years, indoor localization becomes more and more essential in our daily life thanks to its interesting applications that cover all domains including security, tourism. Unfortunately, the existing outdoor localization systems fails in indoor environment, which has motivated researchers to develop new localization systems that challenge the indoor environments. In our work, we propose a 3D fingerprinting-based localization system that estimates a source position using acoustic signals. The latter has the advantage of being used in almost roaming devices. No dedicated infrastructure is necessary and the existing infrastructures can then be reused for indoor purposes. The proposed system has been evaluated in experimental tests in an area of dimensions 1.5 m * 1.5 m * 2 m when four microphones were placed at known positions and an artificial fan is turned on. Results show that turbulence affects the precision of estimating the source position by 7% for an accuracy of 8.5 cm.

Ibn Hazm’s Literalism: A Critique of Islamic Legal Theory (I)
Sabra, Adam
Al-Qantara : Revista de Estudios Arabes , 2007,
Abstract: Ibn Hazm’s insistence that the Qur’an and Sunna be interpreted literally has frequently lead modern scholars to conclude that he is a conservative or dogmatic thinker. In fact, he is neither. Ibn Hazm’s Zahirism emphasizes the limited scope of Islamic law and attempts to curtail the claims made by Muslim jurists to speak on behalf of God’s law. This method leads him to support rationalism, individualism, and anti-clericalism. Ibn Hazm argues in favor of these principles consistently in his works on Islamic legal theory, including the text al-Nubdha al-kafiya fi usul ahkam al-din, which is translated here. This approach promises to undermine the whole madhhab system, which explains the negative response it received from the religious establishment. In place of the madhhab system, Ibn Hazm seeks to assert the individual responsibility of each Muslim to obey God’s law as it is clearly revealed in the sacred texts of Islam. La insistencia de Ibn H
Capital Account Liberalization and Economic Growth: GMM System Analysis
Hichem SAIDI,Chaker ALOUI
International Journal of Economics and Finance , 2010, DOI: 10.5539/ijef.v2n5p122
Abstract: The aim of this paper is to determine the correlation between capital account liberalization and economic growth. We are particularly interested in a qualitative indicator to measure this process. Our empirical study was conducted on a sample of 60 developed and developing countries covering the period 1984 to 2007. Referring to the dynamic panel model, our econometric results reveal a direct correlation between the capital account liberalization and economic growth which can be either positive or negative due to the sample selection and the study period. This leads us to predict the capital account opening is a sine qua non for initiating economic growth.
MOBILE BUSINESS APPROACH BASED ON MOBILE AGENT
Ahmed Aloui,Okba Kazar
International Journal of Digital Information and Wireless Communications , 2011,
Abstract: Users today want the opportunity to make (or manage) a businesses in anytime and anywhere via their mobile devices. This paper proposes the architecture with mobile agent for the mobile businesses (m-business). M-business appeared as the promising approach to drive the vague following one of electronic business (e-business). Most of the e-busines [9] applications uses the traditional model client/server in which a commercial operation requires generally a link of stable communication being established between the customer and the server, and the traditional approach client/server [8] constitutes an obstacle to the development of application of m-business. The proposed architecture introduces several advantages: in the first place, allow the consumers to manage their commercial business driven by types of mobile devices (phones, PDAs, etc. ....) at any time and wherever. Secondly, minimize the waiting time of the customer, and the quantity of transferring information. Third, this architecture addresses the problem of time limited and expensive connection for mobile users. The Mobile agents will be used on a single level: research agent. Every research mobile agent will be used to visit the target server site of the application to collect the informationa€ s for his client, which allows it to interact locally with a server, and so to reduce the traffic on the network by transmitting only the useful data.
Characterization of Some Bacteria in the Waters of Chott of A?n El-Beida in the South of Algeria  [PDF]

Abstract: Hypersaline environments, represented by the chotts, the Sebkhas and the saline soils, etc., are a typical example of extreme environment harboring a particularly interesting microbial flara. In this context, the aim of this word is to try to make a characterization of the bacteria in the waters of the chott of Aïn El-Beida in the region of Ouargla (South Algeria). The water samples taken are characterized by a pH between 6.6 and 8.39, the water is neutral to alkaline water, with a temperature between 8˚C to 10˚C, and an electrical conductivity between 2.4 to 6 ds/m reflecting extremely salty water. These characteristics enabled us to select a microflora specific to this environment. The microbiological analsis of these samples revealed fifteen isolated strains, including the following species: Escherichia coli 2, Flavobacterium meningosepticum, Shigella sp, Aeromonas salmonicida, with a bacterial density that varied between 0.27 × 104 to 2.236 × 104, which may explain why the water in this ecosystem is rich in specific important microflora. The results of NaCl tolerance have revealed to us that certain isolated strains tolerate a NaCl concentration up to 35%, these are euryhaline bacteria. With regard to the antagonist test, the strains (S8) have a strong antifungal capacity, which can be explained by the fact that latter has a significant competitive power against Aspergillus carbonarius and Penicillium sp. The microbial exploration of this specific extreme ecosystem proved successful, as we were able to detect significant specific microbial diversity.
Characterization of a human brain cortical surface mesh using discrete curvature classification and digital elevation model  [PDF]
Kamel Aloui, Amine Na?t-Ali, Mohamed Saber Naceur
Journal of Biomedical Science and Engineering (JBiSE) , 2012, DOI: 10.4236/jbise.2012.53017
Abstract: In this paper we present a novel approach for brain surfacec characterization based on convexity and concavity analysis of cortical surface mesh. Initially, volumetric Magnetic Resonance Images (MRI) data is processed to generate a discrete representation of cortical surface using low-level segmentation tools and Level-Sets method. Afterward, pipeline procedure for brain characterization/labeling is developed. The first characterization method is based on discrete curvature classification. This is consists on estimating curvature information at each vertex in the cortical surface mesh. The second method is based on transforming the brain surface mesh into Digital Elevation Model (DEM), where each vertex is designed by its space coordinates and geometric measures related to a reference surface. In other word, it consists on analyzing the cortical surface as a topological map or an elevation map where the ridge or crest lines represent cortical gyri and valley lines represents sulci. The experimental results have shown the importance of these characterization methods for the detection of significant details related to the cortical surface.

Abstract: The present study was designed to compare the effect of racial variations on short- and incremental maximal exercises in sedentary men whites (WT) and blacks (BT) Tunisian and South African (SA). In a randomized order, thirty-six physically sedentary men including 12 BT, 12 WT, and 12 SA were asked to perform a force-velocity (i.e., determination of maximal power (Pmax), F0, and V0) and a treadmill maximal aerobic (i.e., determination of maximal oxygen uptake (VO2 max)) tests. Pmax and F0 were significantly higher in SA than WT (p < 0.01 and p < 0.05 respectively). However, no significant difference was observed between WT and BT and between SA and BT. Likewise, racial variations didn’t affect the V 0 values. Moreover, VO2 max was significantly higher in SA and BT than WT (p < 0.001). However, no significant difference was observed between SA and BT. Compared to white subjects, the present study’ results suggest the superiority of blacks races on aerobic and anaerobic exercises in physically sedentary men.
A New Useful Biometrics Tool Based on 3D Brain Human Geometrical Characterizations  [PDF]

Abstract: Previous clinical research studies consider the existence of differences among normal individual cerebral cortex and show that some features such as cerebral sulci are unique for each individual so that human brains are anatomically different and unique to each individual. In this work, we highlight the idea which consists in using medical data, such as brain MRI images for the purpose of individual identification or verification. In other words, we raise the following question: can one identify individuals using their brain geometry characteristics? Our aim is to validate the feasibility of this new biometrics tool based on human brain characterization. The proposed approach differs from existent biometrics modalities (e.g. fingerprint, hand, etc.) in the sense that brain features cannot be modified by individuals as it is the case when using fake fingerprints, or fake hands. In this work, we consider volumetric Magnetic Resonance Images (MRI) from which brain shapes are extracted using a 3D level-sets segmentation approach. Afterwards, geometrical descriptors are extracted from the 3D brain volume and from a projected version which provide specific features such as the isoperimetric ratio, the cortical surface curvature and the Gyrification index. Evaluations performed on a set of MRI images obtained from (MeDEISA) database show that it is possible to distinguish between individuals using their brain characteristics. Preliminary results are particularly encouraging.
