In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...

Use of balanced cross-section methods, which assume length and area conservation in two dimensions, to quantitatively analyze fold-and-thrust belts is vital structural analyses. However, layer-parallel shortening beyond this assumption thus indescribable by methods. The contribution accommodating has rarely been determined, especially sections hundreds kilometers scale. In study, we conducted a...

traditional persian architects used to employ the facade ornaments to illustrate cultural values and heritage. moreover, their approach for the adaptation of decorations to structural constructional requirements of buildings, called tectonics, could be considered as a cultural-artistic character itself. although these features were omitted when modernism and its independent facade principle pre...

Although BMD measured by DXA is a useful clinical tool for osteoporosis diagnosis, changes resulting from osteoporosis treatment only partially explain the observed reduction in fractures. Several other bone properties that influence its resistance to fractures and explain this discrepancy have been defined as "bone quality". Bone quality is determined by its structural and material properties ...

Triassic strata are widely developed in the eastern part of Sichuan Basin. The Mingyuexia anticline and Huangnitang located structural belt develop Jialingjiang Formation to Xujiahe Formation. middle Leikoupo Badong on both sides synchronous heterogeneous strata. They distinguished regionally according their different sedimentary environments lithologic characteristics, phase transition boundar...

A method of shape generation using shape grammars which take shape as primitive and have shape-specific rules is presented. A formalism for the complete, generative specification of a class of non-representational, geometric paintings or sculptures is defined which has shape grammars as its structural component. Paintings are material representations of two-dimensional shapes gen~rated by shape...

A character recognition scheme based on structural analysis is presented to deal withunconstrained hand-written characters and degraded samples of multi-font machine-printed characters. It is based on building simplified easy-to-construct shape modelsrepresenting character classes. The scheme is based on employing a general variation anddegradation model to match character sampl...

due to the algorithmic simplicity, cellular automata (ca) models are useful and simple methods in structural optimization. in this paper, a cellular-automaton-based algorithm is presented for simultaneous shape and topology optimization of continuum structures, using five-step optimization procedure. two objective functions are considered and the optimization process is converted to the single ...
