Many existing cross-chain platforms, such as Polkadot and Cosmos, generally adopt a relay-based scheme: A relaychain (relay blockchain) receives and records the state information from every parachain (parallel blockchain), and publish the information on the platform, by which parachains are able to efficiently acquire the state information from one another. In the condition when parachain is consortium blockchain, the cross-chain platform cannot work properly. On the one hand, whether state information is submitted to relaychain is completely decided by the internal decision of parachain. The timeliness of state information cannot be guaranteed. On the other hand, the transfer of state information will be interrupted due to the failure of parachain or relaychain-parachain connection. In this paper, we propose a relay-based blockchain intercommunication framework, called XPull (cross-pulling). Specifically, to ensure the timeliness of state information, we propose a cross-chain state pulling scheme based on cosigned state pulling agreement. To solve the interruption of state transfer, we propose a random scheduling scheme to resume the transfer, or confirm the failure of parachain. The security analysis and experimental results demonstrate that XPull is secure and efficient.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"33 5","pages":"1261-1273"},"PeriodicalIF":1.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10669756","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142159818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Edge nodes become incapable of facing massive tasks due to their own limited computing capabilities, and thus the cloud and edge collaborative environment is produced. In order to complete as many tasks as possible while meeting the deadline constraints, we consider the task scheduling problem in the cloud-edge and edge-edge collaboration scenarios. As the number of tasks on edge nodes increases, the solution space becomes larger. Considering that each edge node has its own communication range, we design an edge node based clustering algorithm (ENCA), which can reduce the feasible region while dividing the edge node set. We transform the edge nodes inside the cluster into a bipartite graph, and then propose a task scheduling algorithm based on maximum matching (SAMM). Our ENCA and SAMM are used to solve the task scheduling problem. Compared with the other benchmark algorithms, experimental results show that our algorithms increase the number of the tasks which can be completed and meet the latest deadline constraints by 32%-47.2% under high load conditions.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"33 5","pages":"1296-1307"},"PeriodicalIF":1.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10669732","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This leads to inconveniences and significant challenges in various image processing fields such as image fusion, denoising, recognition, and segmentation. To enhance the processing ability and recognition accuracy of deformation images, an adaptive algorithm for correcting image deformities is proposed for quadrilaterals and triangles. Firstly, the deformation image undergoes preprocessing, and the contour of the image edge is extracted. Then, discrete points on the image edge are identified to accurately locate the edges. Finally, the deformation of the quadrilateral or triangle is transformed into a standard rectangular or equilateral triangular image using the proposed three-dimensional homography transformation algorithm. This effectively completes the conversion from an irregular image to a regular image in an adaptive manner. Numerous experiments demonstrate that the proposed algorithm surpasses traditional methods like Hough transform and Radon transform. It improves the effectiveness of correcting deformation in images, effectively addresses the issue of geometric deformation, and provides a new technical method for processing deformation images.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"33 5","pages":"1326-1336"},"PeriodicalIF":1.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10669745","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coupled-feed cavity-backed slotted patch antenna is loaded with the ME-dipole. The slotted patch antenna serves as both a radiator and a ground for the ME-dipole. The combination of the ME-dipole antenna and the slotted patch antenna realizes a -10 dB impedance bandwidth covering over 22.86-44.35 GHz (63.9%). The pattern of the antenna element remains stable throughout this bandwidth. The proposed broadband antenna unit not only realizes single linearly polarized (LP) radiation but also can be designed for dual-LP radiation. The dual-polarized radiation can be achieved by changing the slot of the patch antenna to a crossed slot and altering the ME-dipole antenna to a dual-polarization form. A \u0000<tex>$2times 2$</tex>\u0000 dual-polarized array has been designed, fabricated, and tested. A novel dual-polarized feeding network is proposed. To achieve higher isolation, broadband in-phase feed and differential feed are adopted, respectively. A low-loss single to the differential structure is proposed for differential feeding. The simulated isolation of the array is higher than 40 dB.

Specifically, exciting multiple characteristic modes independently achieves pattern reconfigurability and element-reduced multiple-input and multiple-output systems. We furthermore overview a series of works on modes superposition. Various methods have been explored for modal weights decision, and therefore specific patterns are synthesized. The weighted modal combination also fulfills single-element beamforming. A recent study on an antenna design for electrically small unmanned aerial vehicles (UAVs) is summarized, and the desired reconfigurable radiation patterns of the conformal radiator are realized based on CMA. Moreover, a formation-based beamforming technique, which takes advantages of the electromagnetic coupling among conformal radiators and the agility of UAVs, is introduced.","PeriodicalId":50701,"journal":{"name":"Chinese Journal of Electronics","volume":"33 5","pages":"1117-1126"},"PeriodicalIF":1.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10669743","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142159983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
