The Influence of Radiation on Unstable MHD Free Convection over a Vertical Plate in Two Dimensions

2023-12-16T12:14:18+00:00

This research studies the case of unsteady heat flux under the influence of two main factors: thermal radiation and magnetic force across a vertical plate. In order to explore the partial differential equations without introducing the dimensions of energy, momentum and continuity, a set of dimensionless nonlinear systems of partial differential equations were solved using the numerical finite difference method. Because of the assumed parameter ramifications of the velocity and temperature problem are also investigated without dependence on dimensions. Temperatures and momentum profiles are derived via finite differences. Following that, a qualitative and visual presentation of the parameter results on the velocity and temperature profiles is made .

2023-02-28T19:01:42+00:00

Photonic crystal fibers in the late period occupied a wide range of studies and research because of the ease of dealing with them in terms of design and installation, as there is a group of parameters used in them that can affect the refractive index of the pulse propagation through it, including the diameter of the air holes, the distance between the air holes and their number, as this study showed in addition to the aforementioned parameters The effect of temperature on the refractive index was also studied. It has been observed that with an increase in the diameter of the air holes, the refractive index increases and, conversely, the increase in the distance between them leads to a decrease in the refractive index. As for the number of air holes, it has no clear effect. As for the temperature, which is proportional to the frequency and intensity, this increase in temperature leads to an increase in the refractive index of the pulse passing through the photonic crystal fiber. Changing the temperature of the photonic crystal fiber is an interesting for dynamics fine refractive index tuning in active refractive index shift compensation system. this paper present a numerical analysis on the effect of photonic crystal fiber temperature on refractive index and modal features. the research depend on regular hexagonal crystal lattice fibers with specific geometric parameters using finite element method.

Secure Communication Scheme Based on a New 3-D Jerk Chaotic System

2023-02-28T19:02:23+00:00

Chaos theory plays a significant role in the engineering fields and especially in the security of data transmission in communication systems. In this paper, a new 3-D jerk chaotic system has been suggested. The fundamental dynamical properties, including the fixed points, chaotic attractors, bifurcation diagrams, and Lyapunov exponents are investigated. In communication systems, data security and the implementation of designed transceivers of secure communication scheme can be considered the main challenge for applying such systems. In this work, a 3-D new jerk chaotic scheme has been proposed to be used in data encryption of communication systems. The proposed jerk chaotic system is used for constructing identical transceivers of communication scheme that are presented by a master (transmitter) and a slave (receiver). In the master end, a useful information beam is encrypted through a chaotic signal. On the other hand, in the slave side, the original information beam is retrieved from the mutual transmitted beam by a chaotic synchronization mechanism. The communication scheme transceivers are synchronized by an adaptive observer synchronization mechanism. Finally, the system is tested and evaluated on a stream of binary information that is encrypted in the transmitter and recovered in the receiver. The results show that our proposal cryptosystem has good performance in term of securing transmitted data.

A comparative study of combining deep learning and homomorphic encryption techniques

2022-03-27T06:03:09+00:00

Deep learning simulation necessitates a considerable amount of internal computational resources and fast training for large amounts of data. The cloud has been delivering software to help with this transition in recent years, posing additional security risks to data breaches. Modern encryption schemes maintain personal secrecy and are the best method for protecting data stored on a server and data sent from an unauthorized third party. However, when data must be stored or analyzed, decryption is needed, and homomorphic encryption was the first symptom of data security issues found with Strong Encryption.It enables an untrustworthy cloud resource to process encrypted data without revealing sensitive information. This paper looks at the fundamental principles of homomorphic encryption, their forms, and how to integrate them with deep learning. Researchers are particularly interested in privacy-preserving Homomorphic encryption schemes for neural networks. Finally, present options, open problems, threats, prospects, and new research paths are identified across networks

Castor (Ricinus communis) and Sesame (Sesamum indicum) Biodiesel Optimization by Alkaline Na+/K+ Catalytic Conversion.

2022-03-27T06:01:14+00:00

For the optimization of refined castor biodiesel (RCB) and refined sesame biodiesel (RSB), the impacts of specified conditions such as catalysts (NaOH and KOH), catalyst concentration (0.3–1.5), speed (500–750 rpm), and time (20–60 min) were investigated. The physicochemical properties of the RCB and RSB were measured using the American Standard for Testing Materials (ASTM) approved protocols for acid, peroxide, iodine, and saponification; density, kinematic viscosity, and refractive index values. Box–Behnken Design's Response Surface Methodology (RSM) was used for optimization. The results for four optimization methods were catalyst concentration (0.300–0.435 percent), speed (500.000–643.242 rpm), and time (20.000–31.386 min). The yield ranged from 81.062 to 102.648 percent, with a desirability range of 0.812 to 0.980 %. These yields were higher when compared to ASTM D 6751 which required a range of 46–55 % in regular biodiesel production. The RSB achieved a maximum yield of 102.649 % while using KOH, compared to 92.017 % in the RCB when using NaOH. The optimum yield of RCB using the KOH catalyst (89.461%) was higher to that of RSB using the NaOH catalyst (81.062%). The catalyst dosage and its nature, were the most essential factor during biodiesel optimization
