urban green spaces are one of the most important services in modern cities and form a set of urban sustainable development factors which receive considerable attention from urban planners. this paper explains how land use can be optimally allocated to urban public green spaces. in this study, some of the factors influencing urban green spaces in a period from 1373 to 1384 were studied. moreover...

Several recent publications introduce user interface prototypes with non-planar interactive surfaces. Using our own prototype Curve featuring a large vertically curved interactive surface, we want to explore video conferencing and remote collaboration scenarios on non-planar interactive surfaces. We discuss the factors framing, mobility, conception of space and interface compatibility, which mi...

the complex of ce(iii), [ ce (phensc) (h 0) ] (c10 ) , was synthesized using the phensc, a hexadentate ligand,2,9-diformyl-1,lo- phenanthroline bis (semicarbazone), and characterized by x-ray diffraction. the cerium atom has an unusual coordination number of ten involving six donor atoms of the planar ligand in the equatorial plane and four oxygen atoms from four axial water molecules. the comp...

In this paper, an efficient numerical scheme based on uniform Haar wavelets is used to solve the non-planar Burgers equation. The quasilinearization technique is used to conveniently handle the nonlinear terms in the non-planar Burgers equation. The basic idea of Haar wavelet collocation method is to convert the partial differential equation into a system of algebraic equations that involves a ...

A kinematic mapping of planar displacements is used to derive generalized constraint equations having the form of ruled quadric surfaces in the image space. The forward kinematic problem for all three legged, three degree of freedom planar parallel manipulators thus reduces to determining the points of intersection of three of these constraint surfaces, one corresponding to each leg. The invers...
