MLCM: An efficient image encryption technique for IoT application based on multi-layer chaotic maps | ||
---|---|---|
2022 | International Journal of Nonlinear Analysis and Applications | |
The importance of image encryption has considerably increased especially after the dramatic evolution of the internet of things (IOT) and due to the simplicity of capturing and transferring digital images. Although there are several encryption approaches, chaos-based image encryption is considered the most appropriate approach for image applications because of its sensitivity to initial conditions and control parameters. This research aims at generating an encrypted image free of statistical information to make cryptanalysis infeasible. Therefore, a new method was introduced in this paper called Multi-layer Chaotic Maps (MLCM) based on confusion and diffusion. Basically, the confusion method uses the Sensitive Logistic Map (SLM), Hénon Map, and the additive white Gaussian noise to generate random numbers to be used in the pixel permutation method. However, the diffusion method uses Extended Bernoulli Map (EBM), Tinkerbell, Burgers, and Ricker maps to generate the random matrix. The correlation between adjacent pixels was minimized to have a very small value $(x 10-3)$. Besides, the keyspace was extended to be very large $left(2^{450} ight)$ considering the key sensitivity to hinder brute force attack. Finally, a histogram was idealized to be perfectly equal in all occurrences and the resulted information entropy was equal to the ideal value(8), which means that the resulted encrypted image is free of statistical properties in terms of histogram and information entropy. Based on the findings, the high randomness of the generated random sequences of the proposed confusion and diffusion methods is capable of producing a robust image encryption framework against all types of cryptanalysis attacks. |

2021 | Intelligent Manufacturing and Mechatronics , Springer, Singapore | |
Identifying and harnessing energy sources that offer sustainability and reliability have been and continue to be constant challenges in the search for renewable energy resources. Many remote areas of Iraq have grown in recent years; however, nothing has been done to upgrade the power-producing facilities and distribution networks, because updating the system is highly expensive and beyond the capability of a remote area. Renewable energy resources such as solar and wind energy are clean and can be used extensively. Combining these sources with storage batteries can result in better, cleaner, economical and more reliable results compared to a single source. This paper proposes techno-economically feasible and optimal sizing for each component of a hybrid system to generate electricity to a typical house in Zerbattiya, a village located in southeastern |

MPAES: A Multiple-Privileges Access E-Door System based on Passive RFID Technology | ||
---|---|---|
2017 | 7th Scientific Engineering and 1st International Conference “Recent Trends in Engineering Science and Sustainability” | |
Many techniques have been used in achieving secure door systems, with the development of Internet of Things (IoT) and technologies, Access control systems grow differentially and rapidly. This paper proposes a novel reconfigurable embedded system called multiple-privileges access E-Door system (MPAES). Unlike existing E-Door systems, MPAES is developed in such a way that enables the administrator to set multiple access rules to the users. Moreover, a single e-door can be configured to be accessed by a single person or multiple people identification based on passive Radio Frequency Identification (RFID) technology. In addition, unlike the physical keys, the passive tags (keys) can be used to open or participate in opening multiple e-doors. Furthermore, The administrator could control and monitor the access events. In doing so, this paper gives the hardware and software components selection; the architectural design; and the concrete hardware prototyping and dynamic software implementation of the proposed MPAES. Finally, this paper gives the future direction in developing E-door systems. |

Construction of an online examination with resumption of randomization capabilities | ||
2015 | International Journal of Computing Academic Research | |
Online Examination is an essential ingredient in electronic and interactive learning, however, in educational environment most of examinations are done in the classical paper-based way due to the lack of resumption capability when power/network/physical computer’s component failures. For this reason, adopting and developing an online examination system acts as an active research area in recent years. This paper reviews the state-of-the-art and the-art-of-the-practice for nine general-purpose online examination systems found in the literature, as well as, some dedicated industrial systems based on seven elected intertwined features; namely: secure login, resumption capability, multi-instructor, random question selection, random questions distribution, random choice distribution, and portability implementation method. Even though, the implementation of these systems is promising, however, these systems have some bleeding points. For instance, by practicing the existing examinations system, some challenging features are found and others are missing. Among these features; namely: the resumption capability and the combination of randomization features are missing in the reviewed systems. Fix and build from earlier works, this paper proposes an Online Examination System (OLES) that addresses all the elected features to facilitate adopting online examination. OLES is based on spiral model and TCP-IP client/server networking and implemented using Java programming language and Derby database. Finally, a comparison of the proposed OLES versus other related works to distinguish its unique features, and some recommendations for future work are provided. |

Numerical investigation of nanofluids comprising different metal oxide nanoparticles for cooling concentration photovoltaic thermal CPVT | ||
---|---|---|
2022 | Cleaner Engineering and Technology | |
The impact of utilizing Nanofluids with different metal oxide nanoparticles on heat transfer enhancement and fluid flow for concentration photovoltaic thermal the CPVT collector with Fresnel lens is demonstrated using CFD simulation. With the rising temperature, the electrical efficiency and output power of Multi-Junction Solar Cells drop. Four different types of nanofluids and water are utilized as cooling fluids to disperse heat from Multi-Junction Solar Cells by moving the fluid within the mini-channel beneath the PV Solar Cells. In the current analysis, the Reynolds numbers range from 2000 to 18000. For all forms of cooling fluids, the average Nusselt numbers are augmented by rising Reynolds numbers. The CFD results demonstrated that the Nusselt number of all nanofluid cooling fluids is greater than that of water. When compared to water in a CPVT collector, water-SiO2 nanofluid provides the maximum heat transfer improvement of 12.5%. The silicon dioxide nanoparticles have high thermal conductivity, with the water-SiO2 nanofluid exhibiting the greatest heat transfer increase, followed by water-Al2O3, water-ZnO, water-CuO, and water. The average top surface temperature of the mini-channel for the CPVT collector is reduced by 7% when water-SiO2 nanofluid is used as a cooling fluid and by 3.4% when water is used. The usage of water-SiO2 nanofluid has a significant impact on the heat dissipation with high heat transfer enhancement from Multi-Junction Solar Cells in CPVT collector, leading to an increase in electrical efficiency. |

To achieve precise measurements, a vector network analyzer can compensate for the instrument's systematic flaws, the features of cables, adapters, and test fixtures. To check the vector reflection coefficient of microwave devices, we used a low-cost portable VNA (NanoVNA) analyzer with a frequency range of 50 kHz to 4.4 GHz. VNAs are more versatile than oscilloscopes and may be used to explore a wide range of frequency components based on scattering characteristics, smith charts, phase response, and complex numbers. We did some experimental investigations for reported filters and antenna to evaluate the NanoVNA performance and suitability, especially its nonlinear scattering responses.

2020 | Optik | |
In this work, preparation and characterization of Bi2O3 nanoparticles (Bi2O3NPs) by laser ablation in liquid at various laser energy 200, 400, 600 and 800 mJ. X-ray diffraction (XRD) investigation is appeared broad diffraction peak when the size of the crystal becomes inside nanometer. Scanning electron Microscopy (SEM) study results for porous silicon (PS) showed sponge like structure and Bi2O3NPs nanoparticles appear as bright spots. Observed the reflectivity of Bi2O3NPs on PS is less than Si bulk and PS, however. From Raman result show peaks at 81 cm−1 and 303 cm−1 , are the specific bands of α-Bi2O3. The band at 303 cm−1 , are assumed to be because of Bi–O stretches. The electrical properties such as barrier height (ΦB) and ideality factor (n) of the Al/Bi2O3NPs/PS/Si/Al heterojunction were determined from the current–voltage (I-V) measurements. Finally, the variation of operation temperature of NO2 gas sensors which fabricated from the prepared samples on sensor sensitivity, response time and recover time have been studied, and the maximum sensitivity was about 71 % for Bi2O3NPs ablated by laser energy 600 mJ on PS. |

---|---|---|
2017 | optics and laser technology | |
Nowadays, laser tube bending process has become commonly used in laser material processing and fabrication fields because of its ability to produce such forms and shapes that cannot be achieved by normal mechanical bending tools. The process can avoid and overcome most of bending defects like wall thinning, wrinkling, spring back and ovalization. This investigation focused on the experimental, analytical modeling, and numerical simulation to give more understanding of the process. In this work a high power pulsed Nd-Yag laser of maximum average power laser 300 (W) emitting at 1064 nm and fiber coupled has been used to irradiate stainless steel 304 tubes of diameter 12.7 mm, 0.6 mm thickness and 60 mm in length. An analytical model has been used to determine the bending angle by using Matlab program software. The changes of material specification during the laser tube bending process due to the temperature rise has been studied and the analytical model has been modified and enhanced. Particle Swarm Optimization (PSO) was used to optimize the analytical and experimental results and reduce the mean absolute error. © 2017 Elsevier Ltd | ||

2018 | optics and laser technology | |
Laser forming is a flexible control process that has a wide spectrum of applications; particularly, laser tube bending. It offers the perfect solution for many industrial fields, such as aerospace, engines, heat exchangers, and air conditioners. A high power pulsed Nd-YAG laser with a maximum average power of 300 W emitting at 1064 nm and fiber-coupled is used to irradiate stainless steel 304 (SS304) tubes of 12.7 mm diameter, 0.6 mm thickness and 70 mm length. Moreover, a motorized rotation stage with a computer controller is employed to hold and rotate the tube. In this paper, an experimental investigation is carried out to improve the laser tube bending process by enhancing the absorption coefficient of the material and the mechanical formability using laser softening heat treatment. The material surface is coated with an oxidization layer; hence, the material absorption of laser light is increased and the temperature rapidly rises. The processing speed is enhanced and the output bending angle is increased to 1.9° with an increment of 70% after the laser softening heat treatment. | ||

2024 | مجلة جامعة طرطوس | |
In this research, the technical effects of the photovoltaic generation are studied on distribution networks, where we used the ETAP program to analyze the flow of a load using the Newton Rafson method on the IEEE33 test network before entering the distributor generator and after entering it in different proportions and in several locations, and we studied actual and responsive losses as well as the effort On the lowest pans in all cases. We found that adding the photovoltaic generation distributed over the most loaded Basbar, the most far from the source and by 30% is the condition that achieves the best reduction rate of actual loss, as well as the best high voltage rate on low -voltage basb In addition to studying a realistic network, which is part of the Tartous Governorate distribution network (the director of industry), which mainly contains the generation of photo distributed by 24.7%, and it was noted that the actual power losses decreased by 70%, as well as the loss of custodian power by 76%, and the fact that the industry network has geographically separate loads from each other In addition, it suffers from a significant low level of voltage levels, so the distributing optimum generation should not be concentrated on one pamper but rather distributed on several viability. | ||

Considering the various factors that affect dust storms, the independent variables included a set of six meteorological and climatological indicators: wind speed, atmospheric pressure, dust concentration, temperature, humidity, whereas dependent variable, turbulence intensity, was used to measure how turbulent dust storms are examined. Data regarding all the specified variables was accessed from “Geospatial Interactive Online Visualization and Analysis Infrastructure” for a period of twenty years. The findings suggested that there is a meaningful link between the dependent variable and the independent variables for the long-term associations. All have a significant influence on the atmosphere's predisposition to possess the kinetic energy. The significance of this discovery lies in its disclosure of the intricate nature of atmospheric dynamics and their susceptibility to a broad spectrum of external factors. By addressing these obstacles, atmospheric study will progress, and more inclusive models and policies will be developed.

The packaging of Microwave integrated circuits (MIC) is one of the important and sensitive matters in the manufacture of these circuits, which directly affects the performance of the whole system, as the box acts as a cradle for the circuit, which may turn into a resonant cavity under certain conditions, which leads to disturbance in the circuit’s work and instability, to avoid this effect we use a special materials that absorb excited microwaves and do not allow them to reflect and spread within the cavity. β-MnO2 nanoparticles were prepared by the simple hydrothermal method. β-MnO2 was dispersed successfully in Poly Vinylidene Fluoride (PVDF) to form the absorber system (β-MnO2/PVDF) in various percentage ratios. X-ray diffraction indicates prepared MnO2 has a nano crystallite structure (Tetragonal) in beta phase. The percentage of attenuation in all studied ratios at the peaks of curves were around 90%, and percentage of absorbing was around 72.5%, which strongly indicates that (β-MnO2/PVDF) is an excellent absorber material.

Optimizing of Cellular Networks by adjusting the tilt of Base Stations Antennas – Case study (University of Aleppo Region) Using OPNET | ||
2015 | مجلة بحوث جامعة حلب - سلسلة الهندسة الكهروميكانيكية والمعلوماتية | |
Obviously the demand for higher data rates is increasing, and users are often complaining about Call ending problem or the coverage gaps or even decreasing in data rates while using the Internet. For that, mobile network developers have introduced multiple solutions and on multi levels in order to avoid those problems such as increase the bandwidth or the purchase of more frequencies or use advanced multiplexing techniques and improve FEC algorithms. This article discusses the impact of antenna tilting on the network performance so that we can through an integrated system connected to the core network, decrease/increase the tilt of base station antennas to increase/decrease a coverage area or do a load balancing between overcrowded cells after taking measurements from stations into account. Antenna tilting is considered an effective parameter in mobile network optimization process which specify the service area limitations in the cell and signal propagation which in turn effects on interference and fading within the network. It has become easy to control the antenna radiation pattern tilting for improving the network performance after inventing RET (Remote Electric Tilt) which allows the cell boundaries to be dynamic and controlled remotely, which enables the network to do tilt calibrations by itself. |
