Rate splitting based robust secure transmission scheme in RIS-assisted satellite-terrestrial integrated network
Published 2023-12-01“…Firstly, considering a reconfigurable intelligent surface (RIS) assisted satellite terrestrial integrated network, the satellite employed the rate splitting multiple access technique to serve multiple earth stations in the presence of multiple eavers-droppers(Eves), while the terrestrial network leveraged multicast technique to serve many ground users with the assist of RIS.Secondly, assuming that only the Eves’ imperfect channel state information could be obtained, a joint optimization problem was formulated to minimize the total transmit power, while ensuring the quality-of-service requirement for all users, and adhering to intercept probabilistic constraints.To tackle this noncom vex problem, the S-procedure and the successive convex approximation approach were employed to convert the intercept probabilistic constraints into solved ones.And then a nuclear norm-based penalty function was employed to propose a robust joint algorithm to obtain the robust beamforming weight vectors and transmit power.Finally, the simulation results demonstrate the effectiveness and superiority of the proposed transmission scheme.…”

Analysis of Spatio-temporal Evolution of Land Use and Landscape Pattern in Liuxi River Basin Driven by Rapid Urbanization
Published 2020-01-01“…Since the implementation of the policy of reform and opening up,the dramatic evolution of land use and landscape pattern in basins has been brought about by the rapid development of urbanization,threatening the health of its natural eco-hydrological environment.Taking Liuxi River basin in Guangzhou as research object,this paper uses the land use transition matrix and landscape pattern indexes to analyze the spatio-temporal evolution of land use types and landscape pattern based on the land use data of different years from 1980 to 2015.The results show that:①The arable land,which is one of the dominant landscape in Liuxi River basin,was greatly converted to construction land and gradually fragmented and homogenized,resulting in the fragmentation and homogenization of landscape pattern in whole basin;②The dramatic changes of land use types and landscape pattern mainly occurred in the middle and lower reaches,especially during the period from 2000 to 2010;③The rapid growth of total population and the increase of proportion of tertiary industry were main urbanization indicators for the conversion of arable land into construction land.…”

Une caractérisation des indicateurs élaborés dans l’activité. Perspectives sémiotiques sur la formation professionnelle
Published 2021-01-01“…Finally, we develop a “method of indicators” through their characterization in five dimensions: relativity, subjectivity, safety, responsibility and convertibility. Each of these dimensions connects the modalities of the interpretative process to aspects of the activity that they are likely to influence (for example, if the safety of the index chain should always be suspected, in reality, it is done only for specific values of the index). …”

A multi-chroma format cascaded coding method for full-chroma image in AVS2
Published 2018-04-01“…In the second generation of audio video coding standard (AVS2),a multi-chroma format cascaded coding method (MCFCC) for full-chroma (4:4:4 sampling format) images coding was proposed.The MCFCC algorithm firstly converts the 4:4:4 sampling format image into 4:2:0 sampling format image,then the 4:2:0 sampling format image was processed by 4:2:0 sampling format intra prediction,transform,quantization,inverse quantization,inverse transform,entropy coding and a weighted 4:4:4 sampling format distortion calculation method in the rate-distortion optimization process,finally 4:4:4 sampling format in-loop filtering and offset algorithms were applied to the 4:4:4 sampling format image after up sampling.The experimental results show that,for full-chroma natural images,the MCFCC algorithm achieves higher coding efficiency at very low additional encoding complexity and very low additional design and implementation cost.…”

Pattern synthesis method for arbitrary arrays with desired mainloble response
Published 2014-09-01“…A pattern synthesis method based on adaptive array theory and convex optimization principle was proposed for arbitrary arrays,especially considering the influence of different orientation on array pattern.Firstly,the array pattern with special sideloble shape is obtained by adaptive array theory method; and then,the mainloble pointing to 0° is taken as reference to determine the pattern mainloble with variant steering angle.Finally,the optimal array pattern synthesis with desired mainloble response is converted to a second-order cone programming problem.The resulting optimization problem is nonconvex and is implemented via iterative algorithms of convex optimization,which can be solved using the second-order cone programming method at each iteration.Taking the method developed can obtain satisfied mainlobe response and less synthesized error in sideloble region.Theoretical analyses and simulation results show that the synthe-sized pattern has the same mainloble performance as the desired mainlabole in different orientation,and also the sideloble can maintain the shape to suppress the dynamic interference.…”
