حفر تونل باعث از بین رفتن حالت اولیه تنش ها در زمین و جابجایی توده سنگ پیرامون تونل می گردد. بدین ترتیب با حفر مقطع جدیدی از تونل و با گذشت زمان، جابجایی دیوارهها و فشار وارده از طرف زمین بر سیستم نگهداری تونل افزایش می یابد، این تغییرشکل در نتیجه پیشروی سینه کار تونل و رفتار وابسته به زمان (رفتار خزشی) توده سنگ اطراف تونل به وجود می آید. در این تحقیق رابطه ای برای تعیین همگرایی دیواره تونل بر ...
The way that information propagates in neural networks is of great importance. In this paper, we propose Path Aggregation Network (PANet) aiming at boosting information flow in proposal-based instance segmentation framework. Specifically, we enhance the entire feature hierarchy with accurate localization signals in lower layers by bottom-up path augmentation, which shortens the information path...

The DNA duplex corresponding to the entire length (126 nucleotides) of the precursor for an Escherichia coli tyrosine tRNA has been synthesized. Duplex [I] (Sekiya, T., Besmer, P., Takeya, T., and Khorana, H. G.(1976) J. Biol. Chem. 251, 634-641), corresponding to the nucleotide sequence 1-26, containing single-stranded ends and carrying one appropriately labeled 5'-phosphate group, was joined ...
Aiming at the problems of large amount model parameters and false missing detections multi-scale drone targets, we present a novel detection method, YOLOv4-MCA, based on lightweight MobileViT Coordinate Attention. The proposed approach is improved according to framework YOLOv4. Firstly, use an as feature extraction backbone network, which can fully extract local global representations object re...
Abstract When detecting aircraft flared tube defect with the YOLOv4 network structure, tiny object defects will be missed, and resulting in a high missed detection rate low mAP (mean Average Precision) value. This paper proposes an improved algorithm of structure. Firstly, order to improve feature extraction capability for defects, convolution operation is added SPP (Spatial Pyramid Pooling) PA...
Vehicle re-identification (Re-ID) aims to retrieve images with the same vehicle ID across different cameras. Current part-level feature learning methods typically detect parts via uniform division, outside tools, or attention modeling. However, such part features often require expensive additional annotations and cause sub-optimal performance in case of unreliable mask predictions. In this pape...
It has been a challenge in systems biology to unravel relationships between structural properties and dynamic behaviors of biological networks. A Cytoscape plugin named NetDS was recently proposed to analyze the robustness-related dynamics and feed-forward/feedback loop structures of biological networks. Despite such a useful function, limitations on the network size that can be analyzed exist ...
In construction, it is important to check whether workers wear safety helmets in real time. We proposed using an unmanned aerial vehicle (UAV) monitor construction As the small target of photography poses challenges safety-helmet-wearing detection, we improved YOLOv4 model detect helmet-wearing condition photography: (1) By increasing dimension effective feature layer backbone network, model's ...
