Generalized projection method for a variational inequality system with different mapping in Banach spaces

The approximate solution of a system for variational inequality with different mapping in Hilbert spaces has been studied, based on the convergence of projection methods. However, little research has been done in Banach space. The primary reason is that projection mapping lacks preferable properties in Banach space. In this paper, we introduce generalized projection methods. By using these methods, the results presented in this paper have extended the main results of Chang et al.’s and Huang and Noor’s recent works [S.S. Chang, H.W. Joseph Lee, C.K. Chan, Generalized system for relaxed cocoercive variational inequalities in Hilbert spaces, Appl. Math. Lett. 20 (2007) 329–334; Zhenyu Huang, Muhammad Aslam Noor, An explicit projection method for a system of nonlinear variational inequalities with different (γ,r)-cocoercive mappings, Appl. Math. Comput. 190 (2007) 356–361] from Hilbert spaces to Banach space.     

Using pore space 3D geometrical modelling to simulate biological activity: Impact of soil structure

This study is the follow-up to a previous one devoted to soil pore space modelling. In the previous study, we proposed algorithms to represent soil pore space by means of optimal piecewise approximation using simple 3D geometrical primitives: balls, cylinders, cones, etc. In the present study, we use the ball-based piecewise approximation to simulate biological activity. The basic idea for modelling pore space consists in representing pore space using a minimal set of maximal balls (Delaunay spheres) recovering the shape skeleton. In this representation, each ball is considered as a maximal local cavity corresponding to the “intuitive” notion of a pore as described in the literature. The space segmentation induced by the network of balls (pores) is then used to spatialise biological dynamics. Organic matter and microbial decomposers are distributed within the balls (pores). A valuated graph representing the pore network, organic matter and microorganism distribution is then defined. Microbial soil organic matter decomposition is simulated by updating this valuated graph. The method has been implemented and tested on real data. As far as we know, this approach is the first one to formally link pore space geometry and biological dynamics. The long-term goal is to define geometrical typologies of pore space shape that can be attached to specific biological dynamic properties. This paper is a first attempt to achieve this goal.

空气涡轮火箭发动机的性能研究

文中进行了ATR（air-turbo-rocket）发动机总体性能研究，以验证其作为近空间飞行器动力系统的可行性。根据ATR的结构特点，建立了发动机性能和特性分析数学模型．编制了计算程序，在设计点计算和分析了燃料／空气比对ATR性能的影响。计算了非设计点性能．对比了不同推进剂的非设计点性能。计算结果表明ATR能够在宽的速度（0-4Ma）、高度（0-11km）范围内工作，单位推力可以达到1200N·s／kg，比冲达到7000N·s／kg。这一结果表明ATR发动机适合作为近空间飞行器的动力系统。     

Entry into imaginary space: Metaphors of transition and variations in the affective quality of potential space in children’s literature.

In this article the authors use the imaginal worlds of three children’s stories to explore variations in the affective quality of potential space. Lewis Carroll’s Alice in Wonderland, C. S. Lewis’ The Lion, the Witch, and the Wardrobe, and Norton Juster’s The Phantom Toolbooth, each contain a metaphor of transition in which the protagonist moves from the real space of the narrative into the imaginary space where the action takes place—the protagonists are altered and alter their own worlds. The authors will use these metaphors as analogues to differing qualities of imaginary space, including the collapse of meaning in schizoid states, the play of meaning in mentalization and the adventurousness of negotiating separation. These metaphors of transitioning into imaginary space may be used to think about disruptions in development as they manifest in clinical process.

The effects of handedness and reachability on perceived distance.

Previous research has suggested that perceived distances are scaled by the action capabilities of the body. The present studies showed that when “reachability” is constrained due to a difficult grasp required to pick up an object, perceived distance to the object increases. Participants estimated the distances to tools with handle orientations that made them either easy or difficult to grasp with their dominant and nondominant hands. Right-handed participants perceived tools that were more difficult to grasp to be farther away than tools that were easier to grasp. However, perceived distance did not differ in left-handed participants. These studies suggest that, when reaching toward a target, the distance to that target is scaled in terms of how far one can effectively reach, given the type of reaching posture that is executed. Furthermore, this effect is modulated by handedness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
