Title of the Paper: Oxidizing Compounds as Inhibitors of Protein Tyrosine Phosphatases Activity
Authors: Alicja Kuban-Jankowska, Magdalena Gorska-Ponikowska, Pawel Niedzialkowski
Pages: 176-179
Abstract: The results of several studies suggest that the production of reactive oxygen species associated with oxidative stress, may cause inactivation of the protein tyrosine phosphatases (PTPs), and reversible oxidation catalytic cysteine was found to be a major mechanism for regulating their activity. The oxidizing compounds may therefore be considered as protein tyrosine phosphatases inhibitors. In the present paper we investigated the effect of reactive oxygen species such as hydrogen peroxide and activated by him fatty acids on enzymatic activity of protein tyrosine phosphatase PTP1B. Here we presented the IC50 values of hydrogen peroxide, peroctanoic acid and ATA against PTP1B phosphatase, showing that the highest level of inactivation were caused by peroctanoic acid, a product of octanoic acid activated by hydrogen peroxide. However this compound is highly reactive and it can be difficult to consider it as a drug. Taking to account IC50 values of tested compounds we suggest that ATA can be potent inhibitor of PTP1B. The spectroscopic studies also confirmed that inhibitory action of ATA is associated with generation of hydrogen peroxide, which allow to conclude that ATA inactivates PTP1B by oxidation.
Title of the Paper: Manufacturing Aerospace Components using Bionic Technology
Authors: C. Sandu, S. Vintilă, M. Sima, F. Zavodnic, T. Tipa, C. Olariu
Pages: 168-175
Abstract: The rule of thumb in aerospace industry is that lighter is better. Light composite materials have been used in aircraft and turbofan manufacturing for decades, due to their high strength and low density carbon fiber epoxy composite ~1.5(g/cm3) compared with the lightest metallic alloy such as magnesium alloys ~1.8(g/cm3). Nowadays, carbon fiber epoxy composites technology reached a top level in manufacturing fan blades for ultra-high bypass turbofans, but there is still room for improvement by reducing average density of composite components. This paper shows that using bionic technology resembling the structure of a bird bone to manufacture very light fan blades, fan vanes and fan housings is possible, having average densities several times smaller than the most advanced composites materials. This manufacturing technology could lead to very light propulsion systems like turbofans or propfans.

Authors: Mihai Rebrisoreanu, Cosmin Rus, Monica Leba, Andreea Ionica
Pages: 164-167
Abstract: In the context of the fact that blockchain is rapidly becoming the symbol of the fourth industrial revolution, 4IR, only the question of the areas where this technology can be used, remains. Thus, after using in the automotive industry, IOT, finance, health, tourism this technology cannot bypass governmental services. The influence of blockchain technology in the public sector will be largely behind the scenes, but technology has the potential to bring security, efficiency and speed to a wide range of services and processes. In this context, a way should be found for governmental agencies to incorporate the blockchain in the way they operate today. Security, efficiency and speed, the benefits of blockchain technology are easily applicable to public sector organizations, and the potential of technology explains why so many government leaders are actively exploring uses in their governments. Blockchain technology in that it is focused on decentralization and in terms of functioning is transparent can help increase the value of a smart city. From its implementation of electricity transactions to natural resource management, this technology can always find its place in the development priorities of new cities based on smart grid systems.

Title of the Paper: Exploring the Possibilities to Integrate AR in Blogs
Authors: Marius Leonard Olar, Ahmad Saad, Andreea Ionica, Monica Leba
Pages: 153-157
Abstract: Augmented Reality (AR) may enable the use of technology in education in a way that has never been possible before. There is evidence from literature that AR has a positive effect on students learning combined with similar positive effects of using blogs. Two proposed approaches are introduced to harness the power of AR and Blogs in an educational setting: the first is using AR, triggered by markers, to solve a problem and upload the solution in a blog (where the blog is used as an electronic portfolio or E-Portfolio) and the second approach is Engine Based Blog. Both may utilize the power of AR to enhance learning, increase motivation, and provide students with 21st century skills. The first approach is simpler to implement. In this paper there is presented the case of an electronics course that uses AR circuits to solve electronics problems without involving any hardware elements. The second approach is a complex one. There are presented the principles of designing an AR engine for blogs based on an example from an anatomy course.
Title of the Paper: 2-Hyroxyethyl Cellulose Doped with Glycolic Acid as Solid Biopolymer Electrolytes for Solid-State Proton Battery
Authors: Mohd Ikmar Nizam Mohamad Isa, Muhamad Amirullah Ramlli, Nur Ain Bashirah Aniskari
Pages: 146-152
Abstract: Cellulose derivatives have high potential for use as solid biopolymer electrolytes in proton batteries because they are biodegradable, affordable, have good mechanical properties and their ionic conductivity can be enhanced with addition of ionic dopant. In this work, we developed a new type of solid biopolymer electrolytes (SBEs) based on 2-hydroxyethyl cellulose (2HEC) doped with glycolic acid (GA) as an ionic dopant. A solution casting technique was used to prepare the SBEs. The ionic conductivity and structural properties of the SBEs were analyzed using Electrical Impedance Spectroscopy (EIS), Fourier Transform Infrared spectroscopy (FTIR) and an X-ray Diffractometer (XRD). The highest ionic conductivity achieved was 3.80 ×10-4 S cm-1 for the sample with 40 wt.% GA content at room temperature. FTIR analysis showed that complexation occurred in the polymer system from the shifting of ʋC-O and ʋsCOO- band of 2HEC and GA. FT-IR deconvolution revealed the increasing pattern of percentage free mobile ions with the addition of GA content, which resulting in the high ionic conductivity of the SBE. All SBEs shows amorphous nature as proven in XRD characterization.

Thus, we put in place an architecture based on the multi-agent systems MAS which can support the integration of new indicators.
Title of the Paper: An Adaptive Multi-Agent System Architecture for the Smart Home
Authors: Serban Radu
Pages: 131-135
Abstract:A multi-agent model is developed for supporting the architecture of a smart home. The model focuses on embedded devices, sensors framework, actuators and learning algorithms used by smart devices. The agents modeling the smart home receive input from sensors and select a suitable action, which is performed by the effectors. Machine learning techniques make better prediction and also adaptation. The employed smart home model discovers patterns of behavior in the user activities and has the ability to learn these patterns. Also, the used system is able to adapt to the changes in the discovered patterns and to update the model accordingly. The proposed framework has high flexibility, learning capabilities and easy integration with smart objects. The model is tested in a simulated scenario for the smart home, and the agents’ capabilities are improved in time using learning algorithms.

Pages: 126-130
Abstract:The objects of cultural and historical heritage are often located in remote and difficult to access places. Occasionally, reaching them can be related to harmfulness and dangers. Also, buildings and facilities often have places that are narrow, difficult to access, or associated with dangers. Under current control or after an accident, inspections are required at such locations for energy losses due to insulation damage, thermal bridges, moisture, etc. The article describes the possibility of using intelligent mobile robots to transfer capturing, scanning, and thermography technique to narrow, difficult to access or dangerous locations. Approaches for use of mobile robots on outdoor terrain or in enclosed spaces are presented. 3D digitization of the received data were discussed, incl. for people with disabilities. Methods for increasing the energy efficiency of buildings and facilities by analyzing thermograms and using new methods and tools have been also discussed.

Abstract: There are many definitions of the robot, which is a universal machine, used to perform some intellectual, human, motor functions. One of the most important robot classes is manipulating robots for manufacturing operations, which include industrial robots. The construction of flexible manufacturing cells and the industrial robot driving system requires the use of certain techniques of artificial intelligence used to construct superior hierarchical levels, advanced predictive control techniques in inferior hierarchical materialization. The goal of this paper is to make a study on the kinematics of the mechanisms involved in robot composition, the theoretical data of the dynamics of industrial robotic systems and the structure of a robotic position system used in manipulation operations in order to optimize and correct the performances.
Title of the Paper: A Polyvalent Coplanar Coupler on the Ferrite Thin Films with Improving the Dimensioning and Performance
Authors: Rahmouna EL Bouslemti, Faouzi Salah-Belkhodja
Pages: 116-120
Abstract: Couplers are widely used as combiner or power dividers. A different form of CPWG coplanar coupler structures is proposed in this work with a wideband performance. The HFSS is used to optimize the device and to check the transmission characteristics at operating frequency. In this analysis, the coupler studied is a co-directional (COD) at a 2.8 GHz and a transdirectional (TRD) at 2 GHz. The proposed couplers demonstrate noval operating characteristics and non-reciprocal of a clasic coupler which have not been demonstrated before. In this operating mode, the operating frequency of the proposed polyvalent coupler can be selected as desired. All coupler ports can be adapted to a load impedance of 50 Ohm. In addition, the best impedance match on all ports is maintained at all center frequencies. The coupler demonstrates a coupling level of 3 dB with a reflection level of 22 dB and a non-reciprocal isolation level as 20 dB. The polyvalent CPWG coupler have compact sizes of 19×23 mm, with impedance Z0 is 49 Ω.

Title of the Paper: Reconfiguration of Distribution Power System Using Evolutionary Algorithm and Branch Exchange Method for Power Loss Reduction
Authors: Messaoud Belazzoug, Karim Sebaa
Pages: 102-112
Abstract: In this paper, we use an Evolutionary Algorithm (EA) and the branch exchange method to solve the optimal reconfiguration in radial distribution systems for power loss reduction that determine the optimal switches. The EA is a relatively powerful intelligence evolution method for solving optimization problems. It is a population based approach that is inspired from natural behaviour of species. In this paper EA is applied to a realistic distribution system (106 buses) located in the Medea city (Algeria). For the comparison purposes, our method is validated with the classical Branch and Bound (BB) method, widely used by the Distribution Companies. The results confirm the superiority of the EA.
Title of the Paper: Texture-Based Classification Approach to Simulate Absolute Permeability in Reservoir Rock Sample
Authors: Mohamed Soufiane Jouini, Ali Al-Sumaiti, Moussa Tembely, Khurshed Rahimov
Pages: 95-101
Abstract: Carbonate reservoirs represent around half hydrocarbon reserves in the world. However, characterizing rock properties in these reservoirs is highly challenging because of rock heterogeneities revealed at several length scales. In the last two decades, a new approach known as Digital Rock Physics (DRP) revealed high potential to better understand rock properties behaviour at pore scale. This approach uses 3D X-ray Micro tomography images to characterize pore network and also simulate rock properties from these images. Even though, DRP is able to predict realistic rock properties results in sandstone reservoirs it is still suffering from a lack of clear workflow in carbonate rocks. The main challenge is the integration of properties simulated at different scales in order to obtain the effective rock property of core plugs. In this paper, we propose to characterize absolute permeability in a carbonate core plug sample using texture analysis. We propose to segment 3D micro-CT image in terms of textures and predict the overall rock permeability by integrating classification result with absolute permeability simulations values computed locally for each texture class. Finally, we discuss and compare our numerical simulation results with experimental measurement from the laboratory.

Authors: Abdelghani Harrag, Abbes Remita, Ahmed Oussama Bouzaher
Pages: 89-94
Abstract: In this paper we investigate two MPPT commands (P&O and IC) for PV systems. The two algorithms were firstly evaluated independently using fixed and variable step size. In second time, a comparaison between the two methods is carried out. For this, the whole system composed of a PV MSX60 module connected to resistive load via a DC-DC boost converter driver using both proposed MPPTs algorithms are implemented under Matlab/Simulink environment. we were interested in the study and modeling of a photovoltaic system. The obtained results using Matlab/Simulink environment show that the accuracy with the P&O method in the case of high irradiation is less than with the IC method; On the other hand, the precision with the IC method for low irradiation is much less than with the P&O method. As for the response time, the IC method exhibits a better convergence time irrespective of the level of irradiation.

Authors: Abdelghani Harrag, Ahmed Oussama Bouzaher, Abbes Remita
Pages: 79-84
Abstract: Li-Fi is transmission of data using visible light by sending data through a LED light bulb that varies in intensity faster than the human eye can follow. If the LED is on, the photo detector registers a binary one; otherwise it’s a binary zero. This paper introduces the visible light communication technology as a solution for the current telecommunication crunch, also deals with the implementation of the most basic Li-Fi based system to transfer data from one computer to another. Also we have demonstrates the working of Li-Fi by simulating and implementing a simple circuit which gave us the required output. Furthermore we managed to achieve transmission data until 1 meter in daily room with an acceptable noise by using a 10mm ordinary LED and without any encryption technique. This work was done by using Matlab/Simulink code as well as Proteus software for the simulation and the emulation.

Authors: A. Saraiva, R. T. Melo, Vitor Filipe, J. V. M. Sousa, N. M. Fonseca Ferreira, Antonio Valente
Pages: 63-68
Abstract: In this paper we considered the problem of mobile multirobot manipulation, with information extracted from a fixed position camera for command inputs that is analyzed by a real time image recognition algorithm. We used 1320 images for training 11 gesture commands, for decision making we used deep learning through a CNN. The proposed method is evaluated using Kappa’s agreement analysis, with overall score (K), of 0.9708, meaning almost perfect agreement between the prediction of the CNN and the result expected. This approach allows multiple robotic agents to perform collaborative tasks in real time using hand gestures.
Title of the Paper: Some Quality Parameters of Mustards from the Romanian Market
Authors: Cristina Damian, Ana Leahu, Sorina Ropciuc, Mircea-Adrian Oroian
Pages: 58-62
Abstract: Five commercial mustards, made by different manufacturers, were studied to examine their physico-chemical properties and to establish relationships between those properties. Physico-chemical analysis revealed distinct differences between the mustards in the dry matter and extract contents and smaller differences in the protein, fat and ash levels. Two of the investigated mustards did not satisfy the requirements of the relevant Romanian standard regarding dry matter content. The properties of the emulsion were correlated with physico-chemical characteristics of the mustard which can influence the formation and the stability of the emulsion, using principal component analysis (PCA). Statistical analysis of the results showed significant linear correlations between the dry matter, fat, protein and ash contents of mustards and some parameters of rheological model [1].
Title of the Paper: Energy Saving Model for Wireless Sensor Networks: Sports Medical Application
Authors: Imen Kouloughli, Hassine Moungla, Hichem Haddou Benderbal
Pages: 45-50
Abstract: The present paper focuses first on small wireless sensor networks in the medical-sports field. A protocol solution is designed and dedicated to dynamic routing and energy saving. This solution called DREEM (Dynamic Routing Energy Efficient Model) consists of: - A standby strategy, which we propose, and which allows extending the service life of the network, - A locating algorithm called CTA (Closer Tracking Algorithm) used to locate the sensors based on the RSSI metric (Received Signal Strength Indication). To adopt this algorithm for our case study, some necessary modifications were carried out in order to determine the position the athlete was in, and based on that, it became possible to choose a topology that helps to apply the third algorithm of a routing protocol called ELQR (Energy and Link Quality Based Routing) - The routing protocol ELQR in which the status of the link is taken into consideration. Note that in the routing tables, there is also one more column that is especially dedicated to the residual energy of neighboring nodes.
Title of the Paper: Healthcare Monitoring System Using Near-Field Communication
Authors: Bilal Hawashin, Ayman M. Mansour
Pages: 39-44
Abstract: In this paper, a new healthcare system has been proposed that will provide patients with a NFC tag. The NFC tag contains patient information. NFC smart tag can be used when patients and Elderly People go to hospitals or emergency units. Instead of carrying many files they can simply carry the smart tag. Such smart tag can be read using a reader either using smart phone or a reader connected to PC in order to retrieve patient information when placed near NFC tag. This tag can be assigned to patient with a unique ID at the time of registration. Every time the health checkup is performed, it will be updated. This improves patient’s identification by eliminating the paper based documentation work by decreasing mistakes in healthcare. Pharmacist can also view medicine prescribed by the doctor. Data log are stored on centralized cloud server NFC can be used also to identify, query, and update patients data form the server. Doctors can view medical records by tapping his Smartphone that is enabled with a NFC reader over the NFC tag. Such system will improve the quality of healthcare sector by reducing clinical errors resulting of lack of medical information and prescriptions.
Title of the Paper: Legendre Polynomials Active Contour Method for Image Segmentation
Authors: Birane Abdelkader, Hamami Latifa
Pages: 35-38
Abstract: In this paper, we present a novel region based active contour method for image segmentation in the presence of intensity inhomogeneity. We formulate our model based on the SBGFRLS model and the Legendre polynomials. Instead of using the average intensity of the region we represent the regions by a linear combination of a set of Legendre basis functions, which lead to deal with intensity inhomogeneities in the segmentation. In addition, to avoid re-initialization keep the level set function smooth in the evolution process we regularize it using Gaussian filtering. Experimental results on synthetic and real-images show that our method is more robust to initialization, faster and more accurate than the well-known piecewise smooth model.
Title of the Paper: Intelligent System for Defect Detection
Authors: Edson Pacheco Paladini
Pages: 28-34
Abstract: This article describes an intelligent system for defect detection in industrial factories. The system makes an image analysis. The study shows a structure to detect, classify and identifies defects in industrial pieces during the processes they are being produced. The paper explains an automatic process control to detect failures on product appearance, it means, in their externals areas. The evaluation processes consider unlimited defects, it means, those defects whose limits are not clearly defined. Because of common characteristics, the defects appear in inaccurate parts of each analyzed piece. The hardware support involves pattern recognition devices and they are used to detect, identify and classify the defects. The structure of image capture and analysis do not need any human operator to reach a decision about the considered pieces. In addition to describing the model, a typical application is discussed. The practical results obtained are detailed and evaluated.
Title of the Paper: Stability of the Zero Solution of Nonlinear Tumor Growth Cancer Model Under the Influence of White Noise
Authors: Kalyan Das, M. N. Srinivas, Nurul Huda Gazi, Sandra Pinelas
Pages: 12-27
Abstract: The article deals with a system of nonlinear differential equations of tumor growth cancer model under the influence of white noise. This system can be used as mathematical tools for analyzing of various real problems of tumor growth associated with cancer. Necessary and sufficient conditions for the asymptotic mean square stability of the zero solution of this system are derived in this article. The article introduces a new approach to studying such problems through construction of a suitable deterministic system with the use of Lyapunov function. Recently we observed that cell-mediated immunity plays a vital role in immune responses against cancer. Cancer cell development and survival is a multifactor process involving genetic mutation of normal cells with physiological changes within both cancer cells and the body's defence mechanisms. In this paper we considered the special impact of tumor-immune interaction along with the two immune components– resting (helper) T-cells which stimulate CTLs and converting them into hunting (active) CTL cells which attack/destroy/ingest the tumor cells. Critically we have examined the existence of the system with local and global stability analysis at different equilibrium points. We have also developed a theoretical framework for understanding the complexity of the tumor growth cell under the influence of white noise. Using various sensitive hypothetical parameter values with different initial densities the numerical simulations shown the dynamical behaviour of the tumor cells along with the resting and hunting cells showing interesting patterns in the evolution of the tumor and immune cell populations.
Title of the Paper: On Stabilizing Fractional Order Time Delay Systems by First Order Controllers
Authors: Karim Saadaoui
Pages: 8-11
Abstract: In this paper, the problem of stabilizing fractional order time delay systems by first order controller is investigated. The proposed solution is based on finding a set of global stability regions in the controller’s parameter space. One of the controller’s parameters is fixed and the stability region in the space of the remaining parameters is determined using the D-decomposition method. An illustrative example is given to show the effectiveness of the proposed approach.
Title of the Paper: Numerical Simulation of Near Field and Far Field Brine Discharge from Desalination Plants (A Case Study in Persian Gulf)
Authors: Ahmad Rezaee Mazyak, Mehdi Shafieefar, Alireza Shafieefar
Pages: 1-7
Abstract: Seawater desalination has gained importance in coastal countries where conventional water sources are insufficient or overexploited. Seawater desalination contributes to mitigate water scarcity. Brine is a sub-product of desalination plants and is usually discharged into seawaters, with potentially negative effects on marine ecosystems. The process of desalination is not per se environmentally friendly and seawater desalination plants also contribute to the wastewater discharges that affect coastal water quality. Therefore, modelling of the brine discharge dispersion is crucial in the design of coastal desalination plants. In this paper, the salinity dispersion pattern of discharged saline water from the outfall pipeline of SAKO desalination facilities is studied to check the possibility of recirculation and fulfilment of environmental criteria. The SAKO desalination plant has a production capacity of 1,000,000m3/day and is located in northern coast of Persian Gulf, Bandar Abbas, Iran. The salinity dispersion process of a brine jet with ambient water includes near and far field regions. In this research, CORMIX II was used to model the near field process and then check the environmental criteria. The environmental criterion indicates that the excess salinity in a 200 meter diameter from the outfall should be less than 10% of the ambient salinity. Near field simulations indicate that salinity increment in 18 meter distance from the outfall will be about 4.17 PSU which is less than the 42 PSU ambient salinity. Hence, the environmental criteria are thoroughly met. The results of the near field model have been used as input data for the far field model (HD model). The far field model covers north of Qeshm Island and is set up to check recirculation criteria. Results of this simulation have been extracted in the intake location and they show that there is no salinity increment trend at the intake. Consequently, recirculation problem will not happen. Also, results show that the optimization of near field dilution of brine discharge plays an extremely important role in checking the possibility of recirculation and environmental criteria.
