The results show that, the receptance model is very suitable for local modification and analysis of structures.展开更多

Due to its relatively large gain, the use of parabolic antennas has become very popular over time, because they can easily achieve gains of above 30 dB at microwave and higher frequencies. Today, most systems’ success depends on how well the antennas perform. These antennas are available in different types and sizes. Each antenna’s effective area usually has less than the actual physical area of the antenna surface. This means that the unused area of the antenna is massive, and a waste. The aim of the research is to show that the actual physical aperture of a parabolic antenna can be reduced as much as possible to equal the effective area, as given by the antenna formula, thereby saving manufacturing costs, improve the aesthetics. In other words, the focus of this work is to experimentally show that reflector antenna can be made of smaller sizes but better performance. Measurements were taken from different positions from a parabolic antenna, the signal level measured and compared with signal levels for optimal performance.展开更多

文摘It is generally agreed that many Vitis vinifera L.cultivars are self-fertile,where self-pollination often occurs before capfall in a process called cleistogamy.Therefore,it is difficult to identify the right time to remove stamens before self-pollination during the cross-breeding of grape.For this paper,we observed the process of grape flowering and measured the pollen viability and stigma receptivity of grape flowers of‘Shine Muscat’in order to identify the starting time of self-pollination before capfall and to provide useful information for improving the efficiency of cross-breeding.The results demonstrate that the anther is not cracked during the visible clusters and separated clusters stages.Meanwhile,in the separated floral buds,flowering begins,and full bloom stages,the pollen viability is 60.7%,73.2%and 80.3%,respectively;however,at the berry set stage,pollen viability drops to zero.The top of the mature stigma is composed of a layer of nearly cylindrical papillary cells,and the stigma receptivity for pollen changes with the development of flowers:in particular,no reaction was observed in the visible clusters stage;weak positive reaction at the separated clusters stage;strong positive reaction at the separated floral buds,flowering begins,and full bloom stages;and no reaction at the berry set stage.In the separated floral buds stage,pollen tubes were seen germinating in the style.In the flowering begins stage,more pollen tubes were observed at the entry of the ovary.During the full bloom stage,most pollen tubes elongated into the ovary base and some entered the pearl hole.At the berry set stage,newborn endosperm nucleus could be seen in the ovule.From the above,we can conclude that the initiation time of closed fertilization for‘Shine Muscat’grape can be judged as the separated floral buds stage,and it is best to discard the stamen before the separated floral buds stage when conducting cross-breeding.

文摘Mining more discriminative temporal features to enrich temporal context representation is considered the key to fine-grained action recog-nition.Previous action recognition methods utilize a fixed spatiotemporal window to learn local video representation.However,these methods failed to capture complex motion patterns due to their limited receptive field.To solve the above problems,this paper proposes a lightweight Temporal Pyramid Excitation(TPE)module to capture the short,medium,and long-term temporal context.In this method,Temporal Pyramid(TP)module can effectively expand the temporal receptive field of the network by using the multi-temporal kernel decomposition without significantly increasing the computational cost.In addition,the Multi Excitation module can emphasize temporal importance to enhance the temporal feature representation learning.TPE can be integrated into ResNet50,and building a compact video learning framework-TPENet.Extensive validation experiments on several challenging benchmark(Something-Something V1,Something-Something V2,UCF-101,and HMDB51)datasets demonstrate that our method achieves a preferable balance between computation and accuracy.

文摘In oil and gas exploitation,cluster well technology can significantly reduce costs and improve efficiency.An effective adjacent well detection method can greatly reduce the risk of collision between adjacent wells.This study proposes a method to invert the 3D trajectory of an adjacent well using a scattered P-wave obtained by borehole azimuthal acoustic reflection imaging.After obtaining the scattered P-wave from the raw data of the target well using the wave field separation technology,the waveform data in an imaging profile can be obtained by the downhole acoustic directional reception technology.Migration imaging technology is then used to obtain the image of the formation in the imaging profile.Subsequently,by analyzing the images of the formation in the imaging profile of the different azimuths,the well spacing and azimuth of the target well can be determined.Finally,the 3D trajectory of the target well can be obtained by solving the inversion equation.This method was validated by processing the field data from a deviated well in a deep formation.The comparison of the inversion and actual trajectories of the target well demonstrated that the maximum deviation of the inversion trajectory is 0.9 m in the north-south direction,0.78 m in the east-west direction,1.45 m in the well spacing,and 2.48°in the azimuth.The field data inversion result demonstrated that the method can effectively use the azimuth reflection acoustic data to invert the 3D trajectory of an adjacent well,which indicates that the borehole azimuthal acoustic reflection imaging technology has great potential within the context of adjacent well detection.

文摘With the improvement of image editing technology,the threshold of image tampering technology decreases,which leads to a decrease in the authenticity of image content.This has also driven research on image forgery detection techniques.In this paper,a U-Net with multiple sensory field feature extraction(MSCU-Net)for image forgery detection is proposed.The proposed MSCU-Net is an end-to-end image essential attribute segmentation network that can perform image forgery detection without any pre-processing or post-processing.MSCU-Net replaces the single-scale convolution module in the original network with an improved multiple perceptual field convolution module so that the decoder can synthesize the features of different perceptual fields use residual propagation and residual feedback to recall the input feature information and consolidate the input feature information to make the difference in image attributes between the untampered and tampered regions more obvious,and introduce the channel coordinate confusion attention mechanism(CCCA)in skip-connection to further improve the segmentation accuracy of the network.In this paper,extensive experiments are conducted on various mainstream datasets,and the results verify the effectiveness of the proposed method,which outperforms the state-of-the-art image forgery detection methods.
文摘With the advancement of economic globalization,the flow of commodities from one country to another has become closer and closer.Especially in recent years,the logistics industry has been developing rapidly,overseas purchasing agents and cross-border online shopping have been enormously prevailing,and accordingly more and more British and American cosmetics expect to occupy a place in the huge market of China.Therefore,it is particularly important to explore the Chinese translation strategies for British and American cosmetic brands.Based on the theory of reception aesthetics,this thesis takes the corpus Estee Lauder,La mer,and other famous cosmetics brands.The thesis proposes several methods for translating cosmetic brands:transliteration for proper names like person or geography names;free translation to recreate brand aesthetics;creative translation for new brands;and adapted translation for divergence in language habits.Therefore,this thesis is of theoretical and practical significance as far as the field of cosmetics is concerned.
文摘In recent years,a great majority of excellent foreign children' s literary works have sprung up in the domestic market,so the translation of children' literature are drawn much attention.However,the relevant studies which guide the translation of children literature are quite few.Reception Aesthetics which take readers reception as a goal provides a new prospective for the translation of children s literature and promote its development.
文摘In literary translation,creative treason or translation deviations will surely be a shadow in company with each translated work.A translator is both the reader of the source text and the producer of the target text.Applying much on Reception Theory,the present paper explores the issue of translator's creative treason in literary translation in two aspects:one is the translator's creative treason as reader and the other is the translator's creative treason as producer.
