The proposed inverter has a relatively simple structure, but it can provide the buck and boost capability within a single-stage operation.

By employing the characteristic of the switched-capacitor cell, the voltage stress of switching devices is also low. The operation of the proposed inverter is simulated in PSIM. Furthermore, a 400W laboratory prototype is performed to confirm the feasibility and emcacy of the proposed inverter.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130347310","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}

Numerous variational models have been proposed in the literature dealing with Rician noise for MRI data. They, however, are first-order variational models, which suffer the staircase effect and smooth out fine structural details. In this paper, we propose a high-order convex variational model for Rician noise reduction. Unlike other works, our model employs the bounded Hessian regularizer to remedy the staircase effect and preserve small structures. The proofs for mathematical properties, including the convexity of the model, the existence and uniqueness of the solution, are provided. A split Bregman algorithm is developed to solve the proposed minimization problem. All subproblems are solved efficiently by either closed-form solutions or Newton’s method. Experimental results on simulated and real MRI data demonstrate the effectiveness of our proposed model compared with some state-of-the-art variational models for Rician noise removal.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131031150","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}

The experimental scheme includes a helical-waveguide gyro-TWT and a saturable absorber which is based on cyclotron resonance interaction with an initially rectilinear electron beam. Saturation of absorption is caused by relativistic dependence of the gyrofrequency on electrons energy. In good agreement with theoretical predictions, periodical trains of 0.4 ns pulses with peak power of 100 kW and repetition period of 2.5 ns were measured. In addition, we present the results of analysis of an alternate scheme of the pulse generator with passive mode-locking which feature using of two parallel electron beams formed by a single cathode and transported in common vacuumized interaction space that should simplify the practical implementation.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123625697","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}

In the considered network, two transceivers simultaneously transmit and receive information with the aid of one IRS. The artificial noises (AN) are injected to protect information from the attack of an unknown eavesdropper. The aim is to minimize the signal transmission power, i.e., maximize the AN signal power, under the signal-to-interference-plus-noise (SINR) threshold constraints and the total transmission power of the transceivers. The alternating optimization and semidefinite relaxation methods are combined to find the two variable groups of beamformers, AN covariance matrices, and IRS phase shifts.

However, the manual karyotyping process is a labor-intensive task. This paper focuses on automatic chromosome image classification, which is a step in karyotyping. We propose a convolutional neural network architecture for efficient type and polarity classification of the chromosome image, namely ETPC, which is leveraged from the EfficientNet family’s development. The ETPC’s classifier with a weighted classification loss function are designed for efficiency in the training process. We perform our experiment with two training scenarios on four clinical datasets. The experiment on a dataset of 28,225 original chromosome images demonstrates that the proposed network achieved comparable results, with an accuracy of 95.3% for the type classification and 99% for the polarity classification, while having a significantly smaller number of parameters than state-of-the-art methods.

On the other hand, unmanned aerial vehicle (UAV) technology has received increasing interest in many applications from the wireless community. In this paper, we study a downlink (DL) communication network, wherein single-antenna users (UEs) are served by a multiple-antenna base station (BS). To assist the communication between UEs and BS under the assumption of no direct link from BS to UEs, we propose to mount the IRS on the UAV platform in order to exploit the advantages of both UAV and IRS technologies. In particular, the BS beamforming, the IRS phase shift and the UAV placement are jointly optimized to maximize the sum rate performance. Owing to the high coupling properties of the optimization variables, particularly the beamforming and IRS phase shift variables, the optimization problem is naturally non-convex. To effectively solve it, we propose an iterative algorithm by utilizing block coordinate and inner approximation methods. Numerical results are used to show that the proposed approach can significantly improve the system sum rate performance.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129805482","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}
