摘要：We propose a projection-type algorithm for generalized mixed variational in- equality problem in Euclidean space Rn. We establish the convergence theorem for the pro- posed algorithm, provided the multi-valued mapping is continuous and f-pseudomonotone with nonempty compact convex values on dom（f）, where f ： Rn --RU{＋∞} is a proper func- tion. The algorithm presented in this paper generalize and improve some known algorithms in literatures. Preliminary computational experience is also reported.

摘要：This paper extends the results of Matthies, Skrzypacz, and Tubiska for the Oseen problem to the Navier-Stokes problem. For the stationary incompressible Navier- Stokes equations, a local projection stabilized finite element scheme is proposed. The scheme overcomes convection domination and improves the restrictive inf-sup condition. It not only is a two-level approach but also is adaptive for pairs of spaces defined on the same mesh. Using the approximation and projection spaces defined on the same mesh, the scheme leads to much more compact stencils than other two-level approaches. On the same mesh, besides the class of local projection stabilization by enriching the approximation spaces, two new classes of local projection stabilization of the approximation spaces are derived, which do not need to be enriched by bubble functions. Based on a special interpolation, the stability and optimal prior error estimates are shown. Numerical results agree with some benchmark solutions and theoretical analysis very well.

摘要：Aiming at the problem of luminance uniformity for organic lighting-emitting diode (OLED) panels,a new brightness calculating method based on bilinear interpolation is proposed. The irradiance time of each pixel reaching the same lumi-nance is figured out by Matlab. Adopting the 64×32-pixel,single color and passive matrix OLED panel as adjusting luminance uniformity panel,a new circuit compensating scheme based on FPGA is designed. VHDL is used to make each pixel's irradiance time in one frame period written in program. The irradiance brightness is controlled by changing its irradiance time,and finally,luminance compensation of the panel is realized. The simulation result indicates that the design is reasonable.

摘要：基于第一性原理计算,我们通过将客体原子嵌入β-C_(3)N_(2)笼状结构的内在空腔中,预测了机械超硬和可控磁性的共存.以氢掺杂(H@β-C_(3)N_(2))和氟掺杂(F@β-C_(3)N_(2))为例,我们的研究表明两种掺杂构型是稳定的,并发现它们分别属于反铁磁半导体和铁磁半金属.这些有趣的磁相变源于它们在费米能级周围独特的能带结构,并可通过具有半填充占据的3D Hubbard模型和Stoner模型很好地解释.此外,H@β-C_(3)N_(2)和F@β-C_(3)N_(2)的高维氏硬度(49.0和48.2 GPa)表明它们具有笼状超硬材料特征.因此,氢和氟在β-C_(3)N_(2)笼中的掺杂分别产生了一种新型的超硬反铁磁半导体和超硬铁磁半金属,这些材料在极端条件下具有潜在的应用前景.我们的工作为设计具有优异机械性能和磁性的新型高性能多功能材料提供了一种有效的策略,这可能会为超硬材料未来在自旋电子学的应用提供理论依据.

摘要：With the development of sound and light technology, they are increasingly being applied to art exhibitions and creations, and even become an indispensable part of the work of art. Installation art prints are more ornamental interesting, appealing and shocking when being promoted by sound and light technology, but also providing more ideas and methods for creators. The creators but also should pay attention to rational use of sound and light technology to achieve better performance results.

摘要：Environmental awareness is going deeply into the hearts of people in nowadays. Interior environment design of buildings is one of the manifestations of life quality, and furniture is one of the important elements composing interior design. In order to realize using the lowest cost to enjoy the best home life, the paper discusses sustainable design methods from different perspectives, and uses science and technology to integrate art, culture and nature. For the development status of furniture market, the paper researches how to solve the problems faced by furniture market by sustainable design, for achieving continuable, recycle and recoverable objective to control cost and enrich home life of consumer.

摘要：The 4-2-1 family structure has become many old people's choices under market economy circumstance. However,the community service for home care of elderly still has problems such as unsound service system, lack of resources integration, and lack of human resources etc. This paper attempts to construct new mode of cooperative governance of service for home care of elderly in urban community, explore the dynamic mechanism and implementation path for service for cooperative governance of home care of elderly in urban community,point out the power of cooperative governance of community service for home care of elderly,and accomplish institutional innovation such as cultivation of collaborative culture,open power system, flat organizational structure design and group design of public policies etc.
