It can be used to improve the security of fingerprint-based identification systems, especially to guarantee the authenticity of fingerprint images. In this paper, a comparative study of the most used techniques in the field of perceptual hashing is provided, aiming at evaluating their performance when applied to fingerprint images. The study includes five techniques, namely: A-Hash, D-Hash, P-Hash, WHash and SVD-Hash. The performance has been assessed in terms of perceptual robustness, discrimination capability and authentication characteristics, through extensive experiments. The obtained results are promising and show that overall both the A-Hash and P-Hash performed well when compared to other evaluated techniques.Item A DSIM control using artificial neural network controller(University of Oum El Bouaghi, 2021) Hamdi, Naouel; Ourzifi, OuafaThis paper presents a vector control indirect (IFOC) of double –star induction machine (DSIM ) based on artificial neural network (ANN). Double star induction machine are used in high-power applications because they are characterized by efficiency and their ability to power splitting. The objective of this work is the comparison between the CVI indirect vector control with the PI regulator and the CVI indirect vector control with the artificial neural network regulator (ANN) MULTI-LAYER (MLP) found us that the tuning by the neural networks is good and robust in comparison of the PI.

Herein, the optimized cavity design can provide the best sensing performance. In this work, we have numerically simulated with Finite-Difference- Time-Domain (FDTD) method, by varying small change in the geometric parameter we can bring a significant shift in the sensitivity of the device, also we can manipulate the resonance wavelength. The high sensitivity of the biosensor is 2035 nm/RIU. This device can be utilized in the on-chip detection of biochemical such glucose in water and cancer cells with high sensitivity.Item A Low-power and high sensibility of the smart CMOS(Si and 4H-SiC) temperature sensor in 130nm technology(University of Oum El Bouaghi, 2021)One of the many applications of CMOS technology is the design the temperature sensors. In this paper, the electrical performance of smart CMOS(Si and 4H-SiC) temperature sensor in 130 nm technology have been studied using OrCAD PSpice software. The proposed CMOS circuit is developed to provide the first smart temperature sensor based on two different semiconductor technologies (Si and 4H-SiC) integrated on the same chip. These technologies are activated separately according to the temperature range (Low and High). The study of this smart sensor have shown that they operate under a low voltage less than 0.8 V and ultra low power of order nW. In addition, it is characterized by high sensitivity and good linearity across a temperature range from -120°C to 500°C. It is expected that the use of Si and 4H-SiC technologies for both temperature ranges (low and high) respectively will increase the life of this sensor.Item A Magnetically Tunable Planar Band-stop Filter Using Ferrite Layer(University of Oum El Bouaghi, 2021) Zermane, Aziza; Djouablia, LindaA tunable metamaterial band-stop filter using magnetic material is presented in this paper with numerical results. Our filter is based on a 50 Ohms microstrip feed line, three metamaterial resonators and YIG layer. The feed is supplied with a variable magnetic bias in the range of 0- 200KA/m, the central frequency of the filter varies from 10.10 GHz to 12.05GHz (up to 16% tuning) according to the applied magnetic bias, while achieving a maximum rejected bandwidth of 1.2 GHz.Item A Microstript coupler with improving the characteristic transmission(University of Oum El Bouaghi, 2021) EL-Bouslenti, R.; Salah-Belkhodja, F.; Sayah, A. K.In this paper, a new miniaturized microstrip coupler at the center frequency of 3.26 KHz is proposed. Meander line allowed for reducing the size of the component. The coupler demonstrates a coupling level of 2.29 dB, a reflection level of 25.39 dB and an isolation level as 42.41 dB. The meandered coupler have the compact sizes of 23×34.6 mm2, and a characteristic impedance Z0 of 50.60 . in order to validate our model, the compact coupler is designed and fabricated using microstrip technology on FR4 substrat. Good agreement is achieved between the simulated and measured resultsItem A Mise en plqce d'une bqse de donnees pour le cadastere 3D(Université d’Oum El Bouaghi, 2021) Belhouari, Fatima Z; Boukerch, Issam; Si youcef, Kamel; Siddiki, Akram M; Mansour, DahbiaDepuis longtemps, les propriétés se trouvent partiellement ou complètement les unes en dessous des autres. C'est ce qu'on appelle la superposition verticale des propriétés. En raison de leur nature tridimensionnelle, la géométrie de ses propriétés ne peut pas être entièrement représentée sur les plans cadastraux, puisqu'ils ne comportent que deux dimensions, c'est-à- dire généralement la longueur et la largeur de la parcelle. La hauteur ou la superposition verticale des propriétés est donc difficile à représenter sur les plans 2D. Le problème rencontré pratiquement en milieu urbain, signalé par les agents du cadastre au niveau de plusieurs directions du cadastre, la superposition des copropriétés. Dans ce contexte, cette étude vise à proposer une solution pour faciliter la gestion des copropriétés et la représentation sur les plans cadastraux. L'objectif global du cadastre 3D est donc de combiner les deux facettes : compléter la documentation cadastrale urbaine en intégrant les informations sur la copropriété verticale (représentation en volume) et ensuite utiliser les informations extraites de la base de données mise à jour. L'objectif de notre travail est de créer une base de données permettant de stocker, mettre à jour, afficher et représenter les informations sur la copropriété verticale. Nous résumons les différentes étapes appliquées à la conception d'une base de données et à la représentation en volume du cadastre 3D : Examiner les différents types d'immeubles en copropriété verticale existe en Algérie et les classer en quatre catégories. Analyse et prétraitement des données cadastrales pour l'extraction'informations sur la opropriété verticale (état descriptif de division (EDD), base de données cadastrale 2D, fiches cadastrales). Créer une base de données dédiée pour le cadastre 3D en PostgreSQL. Création d'un ensemble de triggers pour chaque type afin de vérifier l'intégrité des informations lors du remplissage de cette base de données.

RPL has been designed for constrained devices and networks. Owing to their constrained power, memory, and processing, RPL-based networks are exposed to a wide range of security attacks that mainly include control message tampering. In this paper, we present a new modified Version Number attack, called Decreased Version Number Attack (DVNA), where the idea behind it is that the version number is decreased instead of increased as in the traditional version number attack. The aim of the attack is to initialize continually the trickle timer of the malicious node's neighbors, which leads to unnecessary exchange of control messages, therefore exhausts the resources of the nodes and reduce the network lifetime. The obtained results show an increase of up to 71% in the exchanged control messages and an increase of up to 47.77 % in energy consumption.Item A new design of high-sensitive photonic crystal biosensor based on ring-shape holes for detecting glucose concentration(University of Oum El Bouaghi, 2021) Daas, Assia; Mouetsi, Souheil; Hocini, Abderraouf; Hocini, Abdesselam; Lariouri, FatehIn this work an optical sensors has been designed and studied with different parameters to select the best result of Q factor and sensitivity; for that, we choose a 2D photonic crystal (PhC). The refractive index (RI) sensor is formed by a pointdefect resonant cavity in the quasi-sandwiched waveguide with a hexagonal lattice of air holes. The properties of the sensor are simulated using a couple of two methods finite-difference timedomain method (FDTD) and the plane wave method (PWE). The calculation results show that a change in ambient RI is apparent; the sensitivity of the sensor is achieved. The objective of our research was primarily modeling and optimization geometry of a first coupling path between a waveguide and a ring resonator with base of photonic crystals in order to improve the coupling properties in this structure. It is in this context that we have exploited all the parameters already developed for improve the biodetection properties in a photonic crystal-based structure. The role of our design is to sens small RI changes for detecting glucose concentration using resonant microcavity (RMC).Item A new lightweight approach to mitigate the version number attack in RPL-based IoT networks(University of Oum El Bouaghi, 2021) Belkheir, Mohammed; Rouissat, Mehdi; Belkhira, Hicham Sid AhmedIn the recent few years, the cybersecurity challenge stood out to the research community with the drastic evolution of IoT networks. The present article deals with the version number attack, a major security concern for IoT networks using RPL as routing protocol. Although a number of techniques have been proposed to mitigate this kind of attack, the main challenge of the proposed technique remains to contemplate the limited capabilities of the embedded devices composing the network in terms of computing, storage and energy. This makes decentralized heavy algorithms and cryptographic solutions not suitable to cope with the inherited resources of nodes and the network core routing operations. The main purpose of our present work is to implement a new lightweight approach aiming to reduce the destructive effect of the version number attack, whereby the node takes into consideration only the version number received from its preferred parent and ignores other versions of its neighborhood. This leads to propagate the same version number value of the root node over the entire network and ensures the network integrity, by reducing the repeated global repair process caused by falsified values of the version number. The proposed method is implemented under Contiki 3.0 operating system and simulations are performed using COOJA for different scenarios while changing the intruder node position in the network. The obtained results obviously depict that our proposed method yields better aftermath, where the energy saving is between 10% and 50%, depending on the intruder position, while the control overhead is between 2% and 50%.Item A Study Of Speckle Noise Reduction Filters for SAR Images(University of Oum El Bouaghi, 2021) Tifouti, Issam; Meriane, Brahim; Rahmouni, Salah; Moussaoui, abdelkrimSynthetic Aperture Radar (SAR) imaging systems can provide valuable sources of earth observation data for various applications. Speckle noise can reduce the image quality of synthetic aperture radar (SAR) and complicate image in-terpretation. Reduction of speckle noise is one of the most important processes to increase the quality of the image. Several filters are widely used to enhance the quality of images by despeckling it. This paper compares six different speckle reduction filters such as Lee Filter, Frost Filter, Kuan Filter, Wiener Filter, Median Filter and SRAD (Speckle Reducing Anistrophic Diffusion) Filter that are applied to the SAR image. The statistical measures SNR, PSNR, SIM, MSE, RMSE are compared and the results are tabulated to determine the filter that is well suited for SAR images. Finally the best filter has been pro-posed based on the statistical and experimental results.Item A Survey on Identity-based Key Management Schemes in Mobile Ad hoc networks(University of Oum El Bouaghi, 2021-05-25) Gasmi, Kenza; Bourouis, Abdelhabib; Benaboud, RohallahMobile Ad hoc networks attract more attention over the years, but the security matter of this type of network makes it hard to achieve all of their advantages. Cryptographic key management is the cornerstone for building any robust network security solution. Identity-based cryptography is a promising solution that resists well the key escrow problem which is suitable for Mobile Ad hoc networks. In this paper, we give an overview of the most important identity-based encryption schemes proposed in the last decade; combined with other techniques to enhance it and provide better results for Mobile Ad hoc networks. Hence, we give a comparative analysis to highlight their advantages and weaknesses. This work gives insights into a recent research to point out its interesting features, take advantages of its strength, ovoid its weaknesses and to lay out the future directions in this area.Item Accounting Education: a theoretical overview(University of Oum El Bouaghi, 2021-05-10) Khalfallah, ZakaryaThe main purpose of this paper is to highlight the Accounting Education as a real asset that must continually evolve in order to best prepare future professionals on accounting for the new requirements imposed by technology and globalization. To do this, a descriptive methodological approach has been deployed to present Accounting Education Standards (IESs), which are developed by the International Accounting Education Standards Board (IAESB). These standards are influencing Accounting Education and training worldwide. The goal of the IESs is to ensure that economic decision makers can rely on the competence of professional accountants regardless of the country where the accountants received their education and training. Two major lessons emerge from this study. On the one hand, that the organizational structure, globalization and technology impact the skills needs of the accountancy profession and, on the other hand, there is a gap between the training provided and the needs of the profession. تستهدف هذه الورقة البحثية تسليط الضوء على التعليم المحاسبي كأداة حقيقية يجب أن تتطور باستمرار من أجل إعداد أفضل المهنيين المحاسبين في المستقبل، وذلك بهدف الاستجابة للمتطلبات الجديدة التي تفرضها التكنولوجيا والعولمة؛ وقد اعتمدت الورقة البحثية في تحقيق أهدافها على المنهج الوصفي التحليلي من خلال تقديم والتي تم تطويرها من قبل مجلس معايير تعليم ،(IESs) معايير التعليم المحاسبي حيث تؤثر هذه المعايير على التعليم المحاسبي ، (IAESB) المحاسبة الدولي والتدريب في جميع أنحاء العالم، كما تهدف إلى ضمان أن صناع القرار الاقتصادي يمكنهم الاعتماد على كفاءة المحاسبين بغض النظر عن الدولة التي تلقوا فيها تعليمهم وتدريبهم.Item Acerola fruit as a natural antioxidant ingredient for gluten-free bread for celiac patients(University of Oum El Bouaghi, 2022-10-23) Bourekoua, Hayat; Różyło, RenataItem Achieving food and energy security between the current and hoped-for reality(University of Oum El Bouaghi, 2023-10-03) Mgadmi, Nidhal; Sadraoui, TarekThe purpose of this article is to analyze the interactions between energy and food security, referred to in this study as the energy-food nexus and the impacts of global risks using the Global Risks Report in the current context of successive crises.
