Roadmap for Establishing Interoperability of Heterogeneous Cellular Network Technologies -2-  [PDF]
Hasni Neji, Ridha Bouallegue
Journal of Signal and Information Processing (JSIP) , 2012, DOI: 10.4236/jsip.2012.33053
Abstract: The global project will focus on an eventual establishment of a holistic understanding of cellular communication, and proposing an ontological approach that expresses the domain’s concepts, classes, and properties in a formal and unambiguous way. However, this ongoing step is about making heterogeneous network technologies explicit and highlighting their commonalities and variabilities. It begins by studying three different cellular technologies, one from each generation (2G, 3G and 4G). After the analysis of Lte-advanced—a fourth generation technology—subject of the first paper [1], Universal Mobile Telecommunication System (UMTS) cellular network—a third generation technology—is the target of this current analysis. The final objective sought is to build Ontology capable of providing a common view of cellular network technologies.
Marketing Religion: The Marketing and Islamic Points of View  [PDF]
Morsy Sahlaoui, Neji Bouslama
American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.64041
Abstract: The purpose of the present paper is to study the possible application of marketing to promote religion in the specific case of “Islam”. In fact, marketing techniques have been adapted to religious goals since the beginning of the 19th century. But with the rise of the secularization movements in the post-modern era, its application becomes vital to guaranty the survival of religions notably in the Christian case. Islam is facing the same difficulties, such as the decrease of mosque attendance, the decrease of religious commitment, xenophobia and Islamophobia. Our approach was to study marketing application such as defining the 4P’s for the religion of Islam. This would be done based on marketing science and the Islam’s sources: The Holly Quran and Prophet Mohamed (PBUH) Hadiths. In the case of Islamic religion’s sources, and specially in Holly Quran and Prophet Mohamed (PBUH) Hadiths we found many similarities with marketing strategy notably in the choice of promotional variables and the insistence on the importance of religious promotion or Islamic Daawah. So we suggest that the use of marketing techniques is possible and would have two major purposes: Developing Islamic religiousness and repositioning Islam’s image as an opened, tolerant and modern religion.

Houda Gharsalli, Monia Attia, Sawssen Hantous-Zannad, Imen Sahnoun, Sonia Maalej, Leila Douik El Gharbi, Henda Neji, Khaoula Ben Miled-Mrad
Open Journal of Respiratory Diseases (OJRD) , 2019, DOI: 10.4236/ojrd.2019.94010
Abstract: Introduction: The high resolution computed tomography (HRCT) is an important part in the diagnostic approach of interstitial lung disease (ILD) associated with connective tissue diseases (CTD) by providing detailed information on the elementary lesion and the radiological pattern of ILD. Aim: to point out the role of HRCT in the diagnosis of ILD associated with CTD (ILD-CTD). Methods: A Retrospective descriptive study was conducted between 2008 and 2017. Data of 24 patients presenting ILD-CTD were collected. A review of HRCT was performed by a radiologist without knowledge of the CTD. Results: Predominant elementary lesion of ILD associated with dermatomyositis (9 cases) was ground glass opacity (n = 9) followed by consolidation (n = 6). Non Specific Interstitial Pneumonia (NSIP) was the most reported pattern (5 cases). Ground glass opacity was also the predominant elementary lesion for the 2 cases of scleroderma and in Sjögren’s syndrome (4 cases/5). NSIP was the predominant radiological presentation in these two CTD. Lymphoid interstitial pneumonia revealed Sjögren’s syndrome in one case. In rheumatoid arthritis (6 cases), the elementary HRCT lesions were irregular interlobular septal thickening (n = 4) and honeycombing (n = 4) consistent with Usual Interstitial Pneumonia (UIP) in 2 cases. Similarly UIP has been described for the 2 patients with lupus and mixed connective tissue disease. Conclusion: HRCT plays an important role in the management of ILD-CTD. Description of the HRCT elementary lesions and the radiological pattern of ILD can be helpful for CTD’s diagnosis.

Abstract: We prove that a family of meromorphic mappings from a bidisc to a compact complex surface, which are equicontinuous in a neighborhood of the boundary of the bidisc, has the volumes of its graphs locally uniformly bounded.
Ontology for Cellular Communication
Hasni Neji
Computer Science , 2012,
Abstract: The lack of interoperability between mobile cellular access networks has long been a challenging obstacle, which telecommunication engineering is trying to overcome. In second generation networks for example, this problem lies in the fact that there are multiple standards. Each of these standards can operate in the same frequency range. However, each utilizes a different Radio Technology and Modulation Scheme, which are characteristics of the standard. Therefore, the lack of interoperability in 2G occurs because of the lack of standardization. Interoperability within 3G networks is limited to a few operating modes using different Radio Transmission Technologies that are not inter-operable. Thus, interoperability remains an issue for 3G. 4G technology even being successful in its various trials cannot guarantee the interoperability. This is within each network generation; meanwhile between heterogeneous network generations the situation seems to be worst. This approach is first to analyze the structure, inputs, and outputs of three different cellular technologies, performing a domain analysis (of this subset of technologies) and producing a feature model of the domain. Finally, we sought to build an ontology capable of providing a common view of the domain, providing an effective representation of relations between representations of corresponding concepts in different cellular technologies.
Aux sources du discours argumentaire Aristote et la Rhétorique
Henda Dhaouadi
Synergies Monde Arabe , 2011,
Abstract: Cet article explore la Rhétorique d’Aristote à travers ses trois Livres afin d’éclaircir la question de l’argumentation dans le discours. Rappeler les grandes lignes de cet ouvrage fondateur nous permet d’appréhender la question tant débattue de l’homme et du pouvoir qu’il exerce grace au langage. Le discours dans la cité grecque était institutionnalisé et régulé par toute une tradition oratoire dont Aristote révèle ici les grandes lignes. Au lecteur actuel de tirer profit de cette longue étude afin de mieux comprendre le fonctionnement du discours et même de réhabiliter la parole dans la cité moderne.
Hydrothermal Synthesis of V3O7..H2O Nanobelts and Study of Their Electrochemical Properties  [PDF]
Mohamed Kamel Chine, Faouzi Sediri, Neji Gharbi
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.28129
Abstract: Vanadium oxide hydrate V3O7..H2O (H2V3O8) nanobelts have been synthesized by hydrothermal approach using V2O5 as vanadium source and phenolphthalein as structure-directing agent. Techniques X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectroscopy and nitrogen adsorption/desorption isotherms have been used to characterize the structure, morphology and composition of the nanobelts. The V3O7. H2O nanobelts are up to several hundreds of nanometers, the widths and thicknesses are 90 and 40 nm, respectively. The electroactivity of the nanobelts has been investigated. The as-synthesized material is promising for chemical and energy-related applications such as catalysts, electrochemical device and it may be applied in rechargeable lithium-ion batteries.
The Effect of a Multihollow Cathode on the Self-Bias Voltage of Methane RF Discharge Used for a-C:H Deposition  [PDF]
S. Djerourou, K. Henda, M. Djebli
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.29113
Abstract: In this work we report the measurement of the self-bias voltage of radiofrequency (RF) capacitevely coupled plasma, with a multihollow cathode and methane precursor, used for amorphous hydrogenated carbon (a- C:H) thin film deposition. The plasma is produced in the incident power and pressure ranges between 20 - 300 W and 10 - 100 mTorr, respectively. It was found that the self-bias voltage Vdc is a linear function of the square root of the incident power WRF. The relationship between the self-bias voltage and gas pressure P is established; this gives an empirical relation for (p/p0)y . From this result, the pressure p0 corresponding to the transition from hollow cathode effect to hollow cathode arc effect is determined.
Unsteady Cavitation Analysis Using Phase Averaging and Conditional Approaches in a 2D Venturi Flow  [PDF]
Vincent Aeschlimann, Stéphane Barre, Henda Djeridi
Open Journal of Fluid Dynamics (OJFD) , 2013, DOI: 10.4236/ojfd.2013.33022
Abstract:

The present study refers to a cavitating Venturi type section geometry characterized by a convergent angle of 18° and a divergent angle of about 8° where the sheet cavity presents typical self-oscillation behavior with quasi-periodic vapor clouds shedding. This work is an extension of previous works concerning void ratio measurements and velocity fields using double optical probe and constitutes a complete analysis of the two-phase structure of unsteady cavitating flow. This paper provides a new method based on conditional and phase averaging technique with wall pressure signal to treat experimental data in order to evaluate more precisely time-averaged and rms values of the void ratio and instantaneous velocity fields. Conditional analysis shows a different behavior of the two-phase flow dynamics leading to highlight high void ratio events linked to the break-off cycle. Unsteady phase averaging of the optical probe signal gives the evolution of the void ratio at each studied location in the venturi and shows that the fluctuations close to the wall (where the re-entrant jet is predominant) are in phase with the upper part of the cavity instead of the thickness of the cavity which is unchanged.

Agricultural Sciences (AS) , 2015, DOI: 10.4236/as.2015.65049
Abstract: Rooting ability in Vitis vinifera L. is the phenomena studied. The evolution of the total lipids contents and fatty acids amount of cuttings during the rooting were determined. Total lipid extraction was carried out by an extraction solvent consisting of a mixture of chloroform and methanol. Methylation of fatty acids was carried out by the boron trifluoride methanol complex. Their analysis is performed by gas chromatography. We have obtained a content of merithallus lipids equivalent with then in bibliography. In other hand 3 fatty acids were obtained: eicosapentaenoic acid, oleic acid and docosanoic acid. Among the studied of rooting abilities, we observed decreased levels of total lipids and in the essential fatty acids: eicosapentaenoic acid C20:5 n-3 and oleic acid C18:1 n-9. Minor fatty acids cuttings experimental have a variable evolution. Lipids and certain fatty acids may be markers of rooting in the vine.
