The nanosensor is embedded in direct nonlinear electrostatic voltage DC, harmonic excitation, structural damping, two piezoelectric layers and nonlinear van der Waals (vdW) force. Hamilton’s principle and Galerkin technique respectively are used to obtain the governing equations and boundary conditions and to solve the equation of motion. For this work, effects of surface/interface energy, size and, material length scale parameters on pull-in voltage VDC\u0000and dimensionless natural frequency (DNF) are consided and nonclassical theories compared with classical theory. It is concluded that ignoring nonclassical effects lead to inaccurate results in vibrational response of the MWPENS.\u0000In all boundary condition, S/I effects lead to increasing of MWPENS stiffness leads to more DC voltage to reach the pull-in instability and other nonclassical effects lead to decreasing of MWPENS stiffness and as a result decreasing of DNF. Also, with ignoring the surface/interface density ρ^I,S and Lame’s constants μ^I,S,\u0000respectively the system will have a maximum and minimum DNF than the other parameters and MWPENS respectively will later and sooner than other parameters reach the pull-in voltage.","PeriodicalId":13929,"journal":{"name":"International Journal of Circuits, Systems and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84644631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the high-speed moving veneer image is collected on the conveyor belt, the image appears blurred, making it difficult to accurately identify the defect type and estimate the defect area. To solve this problem, this study compared three image restoration methods including unnatural L0 sparse representation (L0), multi-scale convolutional neural network (MSCNN), and scale-recurrent convolutional neural network (SRCNN). To perform the comparison analysis, a wood veneer image acquisition system was developed and it provided a wood veneer image dataset with 2,080 groups of blur-clear veneer image pairs. Analysis results showed that the SRCNN method performed better than the other two methods. At four different wood moving speeds, the peak signal to noise ratio (PSNR) of the SRCNN was 4.64%, 14.63%, 18.48%, and 25.79%, higher than the other two methods and structural similarity (SSIM) was less than 2%. The average time for this algorithm to restore a blurred wood veneer image was 13.4 s. The findings of this study can lay the foundation for the industrialized detection of wood veneer defects.","PeriodicalId":13929,"journal":{"name":"International Journal of Circuits, Systems and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77960360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike the existing works that use block codes to hide information using the steganographic process, in this work, we propose the use of convolutional coding theory in steganography to encrypt and decrypt messages methods to decrypt messages. Here, we suggest a steganographic protocol based on convolutional codes in which they are defined as discrete linear dynamical systems with which the properties on controllability and observability characteristic of linear systems theory can be applied, in particular the properties of output observability character which can be easily described using matrix language. The proposed decoding algorithm used for dissimulation is a linear decoding method, which has decreased both the time and space complexity, compared to the Viterbi decoding algorithm, sometimes used in other cases; indeed, we go from 2h.n to 2h=2.n, in memory space (with h: constraint height, and n: length of cover object). Moreover, the time complexity is better, while we can also denote that with the convolutional approach, we intend to take advantage of the time-depending transaction.","PeriodicalId":13929,"journal":{"name":"International Journal of Circuits, Systems and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85376992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two-stage hybrid differential evolution particle swarm optimization algorithm is used to solve the model. In the first stage, differential evolution algorithm is used to produce new individuals, and in the second stage, particle swarm optimization algorithm uses a new speed update formula. In the first stage, in order to ensure that the optimal individual will not be destroyed by crossover and mutation, and to maintain the convergence of differential evolution algorithm, we try to introduce Elitist reservation (ER) strategy into differential evolution algorithm. In the second stage, we use a kind of Particle Swarm Optimization (PSO) algorithm with dynamic inertia weight. Through the dynamic change of inertia weight, the global search and local search ability of the algorithm can be adjusted flexibly. The case verification shows that the hybrid differential evolution particle swarm optimization algorithm can effectively solve the RLPMP model, and then effectively improve the balance of multi-project resources.","PeriodicalId":13929,"journal":{"name":"International Journal of Circuits, Systems and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76861550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary to strictly synchronize the acquisition time of borehole and surface monitoring nodes. However, the synchronization signal transmission through the logging cable will cause a delay. In this paper, a calibration method designed to compensate for the deviation of time synchronization due to long-distance transmission on the logging cable. First, the transmission delay of the pulse per second (PPS) is measured in the delay measurement stage. The delay from the global positioning system (GPS) module to all monitoring nodes can get in sequence. Second, In the delay compensation stage, each monitoring node is delayed for a particular time to ensure that all nodes start working simultaneously. Finally, a high-precision clock source is designed to drive the analog-to-digital converter (ADC) to avoid the crystal oscillator’s accumulated error. To verify the accuracy of the calibration method, the modules were tested separately. The length of the logging cable used is 3000 meters. Through experimental verification, the method in this paper can be used to accurately control the time synchronization of different monitoring nodes in the borehole and on the surface within 1us.","PeriodicalId":13929,"journal":{"name":"International Journal of Circuits, Systems and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83118372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
