契合形态与产品设计

“契合”是形态设计的方式之一,它来源于平面图形的“共线共形”手法,被用于中国的很多传统设计中,契合形态实质上是既对立又统一的整体。在现代社会中,契合形态的产品既满足和扩大了实用功能价值,又具有独特的精神功能,是产品“外形”的契合与“神态”的契合。进行契合形态的设计时,要综合考虑单体形态、整体形态以及单体如何契合成为整体这三者之间的关系,将这三者构成系统来设计。

Structural design sensitivity using boundary elements and polynomial response function

This main issue of this paper is a conjunction of the structural design sensitivity analysis using the Boundary Element Method with the polynomial response function determination. The procedure is so general that it enables sensitivity analysis for potential and elasticity problems within both homogeneous and heterogeneous plane and 3D problems. The essential difference with respect to the previous approaches like the Direct Differentiation Method or the Adjoint Variable Method is in discrete evaluation of the structural response using the response polynomials of some state parameters and design variable as the independent parameter. Such a determination is carried out via the several solutions of the given boundary value problem, where design parameter mean value is regularly perturbed in each of the solutions to cover the closest neighborhood of this mean value. Those few solutions make it possible to recover the polynomial response function from node-to node within the boundary elements, so that further symbolic differentiation using MAPLE returns the sensitivity gradients particular values. The entire procedure is tested here twice—first example deals with the homogeneous cantilever beam, where comparison against pure analytical differentiation is done and, separately, for two-component composite cantilever, where such a comparison is made against the central difference method linked with the same BEM solution.

The SRV constraint for 0/1 topological design

In density-based topological design, 0/1 solutions are often sought, that is, one expects that the final design includes either elements with full material or no material, excluding grey areas. The accepted technique for achieving binary values for the densities is to use a solid isotropic microstructure with penalization (SIMP) material for which Young’s modulus is a polynomial function of the otherwise continuous relative densities. This approach indeed enhances 0/1 solutions in a significant manner and as such it has achieved prominent status in topological design. Nevertheless, this paper proposes a possible alternative to the SIMP methodology for generating 0/1 structures. The design variables are still the densities of the finite elements but Young’s modulus is a linear function of these densities (in some sense, a SIMP material without penalty). In order to drive the solution to a 0/1 layout a new constraint, labeled the sum of the reciprocal variables (SRV), is introduced. The constraint stipulates that the SRV must be larger or equal to its value at a discrete design for a specified amount of material. It is understood that this implies a minimum gage on the design variables, a provision which is also present in the standard fixed-grid formulation to avoid singular stiffness matrices. The technique turned out to be very effective in conjunction with the method of moving asymptotes (MMA) when using topological design methods for finding optimal layouts of patches of piezo-electric (PZT) material in order to minimize the mechanical noise emanating from vibrating surfaces. It also performed satisfactorily in classical structural topological design instances, as can be seen in the numerical examples that illustrate this work.

The User-Oriented Bengali Easy Orthography

A work on user-oriented Bengali orthography has been carried out while teaching Bengali as a Third language. Learning Bengali is difficult because of the presence of innumerable conjunct letters and the absence of a vowel-sign for the first vowel in Bengali orthography. It is extra difficult for foreigners because the working memory in learning a foreign language is quite limited. It is easy to make a computer-key-board with a thousand letters and signs, but it is difficult to use in practice. It is shown in this work that the Bengali conjunct letters not used as initial letters in word-making were redundant in its orthography and could be dissected to their components, if a missing-letter sign for the unborn first Bengali vowel-sign was raised in accordance with Bengali orthographic rule. Only 30 conjunct letters used in Bengali as initial letters in word-making which could be kept intact. Thus only 108 signs on a key-board, including 10 digits and 20 punctuation and other signs were sufficient in case of a user-oriented Bengali orthography. This revised version was published online in July 2006 with corrections to the Cover Date.

General programmes for least pth and near minimax approximation

User-oriented computer programmes in FORTRAN IV for discrete least pth approximation with a single specified function, and more generalized discrete least pth approximation with various specifications, which may also be used for non-linear programming, are presented. Values of p up to 10" can be used successfully in conjunction with efficient gradient minimization algorithms such as the Fletcher-Powell method and a method due to Fletcher. It has been demonstrated how efficiently extremely near minimax results can be achieved on a discrete sot of sample points using this approach and the programmes written verify this. The programmes may be applied to a wide variety of design problems with a wide range of specifications. They are suitable for electrical network and system design and such problems as filter design.
