Image encryption is a technique to ensure security in information transfers. The current paper presents an evolutionary model on the basis of a hybridization of DNA biomolecule operators and the LS2 Map chaos function for encryption of image. The model proposed here includes three stages. In the initial stage, the MSC (Magic Square Chaotic) algorithm and a secret key are utilized with the SHA-256 algorithm to determine the initiating the LS2 Map function value, which is then employed to manipulate the pixels of the image. Then, DNA biomolecule operators and the chaos function are used for propagation. Additionally, the previous stages process is iterated with the starting population of the genetic algorithm in the third stage. Afterward, the optimization is carried out through genetic algorithm operators. The results indicate that the introduced model is superior to other rivals. Furthermore, as for the high level of entropy obtained, the model exhibits strong resistance to common attacks. پرونده مقاله -

Sensors transfer measurements from the physical part to the control and cyber part and while actuators that play the role of applying control signals to the physical part. The placement of sensors and actuators is an important issue for ensuring system’s observability and controllability. This placement should be done in way that the system remains controllable and observable with fewest number of sensors and actuators.. Minimizing the number of sensors and actuators has a significant effect on cost and energy reduction. In this study, a new approach is introduced based on the existing paths and non-existent paths between the states of a system. In the proposed approach, the non-existent paths are defined as infinite paths. The best nodes are selected as the location of sensors and actuators based on the infinite paths and their numbers. The numerical simulations illustrate that the Infinite Value Algorithm has performed better in the placements in this way that it has consumed the unique solution in less time compared the Genetic Algorithms. پرونده مقاله -

During this formulation, a convergence and strictly passive state-observer is provided to have passive closed-loop system. Some definitions and charts are defined here for time-invariant and time-varying systems in different scenarios. A new interconnection between passivity of subsystems and passivity/stability of the closed-loop system has been introduced from a different point of view. All definitions are organized based on the systematic method called “virtually Euler-Lagrange” form of passivation. Utilizing this form and theses definitions, make the design process simpler and straightforward, while, some conditions of design will be released due to using these definitions. The designed controller/observer has been applied to control the hepatitis B virus infection disease. The reliability of the proposed definitions are examined by using MATLAB/SIMULINK, while, the results demonstrate the ability and power of this novel approach. پرونده مقاله -

RF چکیده کاملIn this paper, a novel technique to improve the input dynamic range and bandwidth of the microwave power detectors (PDs) simultaneously is presented, which utilizes the piecewise linear approximation in conjunction with the distributed structure to achieve the goals. RF to DC conversion is proved for the proposed PD core, including only a MOS transistor that is capable to convert a part of its RF input signal to a DC value, proportional to the RF input power. This is an efficient method that requires less number of active devices and therefore saves more power consumption and active chip area, rather than the previous conventional methods. The analysis of circuit based on the transmission line theory is discussed and the transfer function is extracted mathematically for the proposed model. Moreover, a transistor level design is performed using a 0.15um pHEMT GaAs technology for 24GHz applications. The post layout simulation results are presented. پرونده مقاله

For this purpose, four sandwich beams of GFRP laminateskins and Nomex honeycomb core are considered. The models have been chosen so that they could cover all failure modes according to available experimental failure mode maps. Models are created and analyzed based on standard 3-points bending test, using ASTM standard C393-62. In order to investigate the effect of loading and sandwich panelparameters on failure behavior, finite element analysis has been utilized. The results are verified by comparing experimental and theoretical results. The constructed failure mode map shows dependence of failure mode on the ratio of skin thickness to span length, and honeycomb relative density. To Then, effect of temperature on the failure modes ofsandwich panels, has been investigated. Results show that failure modes haven’t depended on environment temperature and failure load decreases by increasing environmentaltemperature. The slope of reduction is a function of beam geometrical parameters.Depending on the parameters, the failure loads decrease between 10% to 40% byincreasing environmental temperature. پرونده مقاله -

The performance of induction motors is influenced by their supply voltage; thus, such faults as short circuits can lead to their instability. Distributed Generation Units (DGUs), recently applied by electric utilities and consumers with a remarkable growth, can provide the desired ctive power based on a proper control algorithm and configuration of such voltage source converters as parallel, series and hybrid in one hand, and compensate for various power quality and voltage regulation problems, on the other; hence so called Flexible Distributed Generation (FDG). In this paper, a new interface is introduced for onnecting DGUs to the distribution network. The proposed interface is not only able to provide some portion of active power to loads, but also maintains the nominal voltage for a wide range of operational conditions. Hence, it can replace such compensation devices as Distribution Static Compensators (D-STATCOM) or On-Load Tap Changer transformers (OLTC), which have already being used for voltage regulation of distribution networks. Within the interface, a fuzzy controller is used for the voltage control loop. Computer simulation in MATLAB Simulink proves the performance enhancement of the interface. پرونده مقاله -

Using active loads in the first stage and improved recycling structure, the effective trans-conductance of the first stage is increased. Nonlinear current mirror boosts the current of the second stage; Therefore, Slew Rate (SR) is increased. The class-AB technique is achieved without enhancing power dissipation and without unity-gain bandwidth (UGBW) or noise deterioration. The efficiency of the proposed OTA is evaluated by several simulations in a 0.18μm CMOS process with the 1.8 V supply voltage. This technique is very helpful for high amplification, stability, and low power applications. From the simulation results, the two stage amplifier gives better performance compared to other topologies, especially in terms of gain, output swing, slew rate and unity-gain bandwidth. The circuit is able to achieve 95 dB gain, a 3V output swing, a 169 slew rate and a unity-gain bandwidth of 344 MHZ with a power supply voltage of 1.8 V. پرونده مقاله -

As an estimator, both the kernel function and its parameters can significantly affect the prediction precision of CVR. In this paper, a method to improve CVR performance using pre-processing based on data feature extraction and Grid algorithm is proposed to obtain appropriate parameters values of the main formulation and its kernel function. The CVR estimated mean absolute error rate here is the evaluation criterion of the proposed method that should be minimized. In addition, some benchmark datasets out of different databases were used to evaluate the proposed parameter optimization approach. The obtained numerical results show that the proposed method can reduce the CVR error with an acceptable time and space complexity. Therefore, it is able to deal with very large data and real world regression problems. پرونده مقاله
