Models are matched in their entirety, depending on overall topology and geometry information. A currently open challenge is how to perform partial matching. Partial matching is important for finding similarities across part models with different global shape properties and for the segmentation and matching of data acquired from 3D scanners. This paper presents a Scale–Space feature extraction technique based on recursive decomposition of polyhedral surfaces into surface patches. The experimental results presented in this paper suggest that this technique can potentially be used to perform matching based on local model structure. In our previous work, Scale–Space decomposition has been used successfully to extract features from mechanical artifacts. Scale–Space techniques can be parameterized to generate decompositions that correspond to manufacturing, assembly or surface features relevant to mechanical design. One application of these technique is to support matching and content-based retrieval of solid models. This paper shows how a Scale–Space technique can extract features that are invariant with respect to the global structure of the model as well as small perturbations that 3D laser scanning process introduce. In order to accomplish this, we introduce a new distance function defined on triangles instead of points. We believe this technique offers a new way to control the feature decomposition process, which results in the extraction of features that are more meaningful from an engineering viewpoint. The new technique is computationally practical for use in indexing large models. Examples are provided that demonstrate effective feature extraction on 3D laser scanned models. In addition, a simple sub-graph isomorphism algorithm was used to show that the feature adjacency graphs, obtained through feature extraction, are meaningful descriptors of 3D CAD objects.

Shape optimization solves another class of problems involving continuous structural components where the optimum shape (the shape of the boundaries and the surfaces of the components) is determined. This report describes shape optimization of three-dimensional structural components. The finite element method of analysis is used employing the 20-noded isoparametric element. The objective function, mass, is minimized by the direct use of nonlinear mathematical programming, specifically the feasible direction method. Numerical shape representation and the selection of design variables are the most important aspects of the problem. The problem is addressed from a practical standpoint and techniques are presented to minimize the number of desingn variables. Isoparametric representation of the surfaces and the numerical superposition of shapes are discussed. These techniques are compared and demonstrated on simple cantilever beams and their minimum mass designs are obtained. In one example, the optimum shape of a non-uniform cross-sectinal beam is obtained under stress constraint. The final design has a crosssectional shape varying over the length of the beam which could not be predicted using the bending theory of beams. One major difficulty encountered in some problems was that the shape changes during the optimization process may require a change in the finite element mesh because the initial configuration of the finite element mesh may result in very distorted elements for the new shape. The analyis with a mesh containing distorted elements may not be possible at all or the results of the analysis may be inaccurate.", "publicationTitle": "International Journal for Numerical Methods in Engineering", "publisher": "", "place": "", "date": "1982", "volume": "18", "issue": "5", "section": "", "partNumber": "", "partTitle": "", "pages": "661-673", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1002/nme.1620180504", "citationKey": "", "url": "http://dx.doi.org/10.1002/nme.1620180504", "accessDate": "2009-05-26T04:45:53Z", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "Wiley InterScience", "callNumber": "0155", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2009-06-26T05:43:31Z", "dateModified": "2011-06-17T06:05:05Z" } }, { "key": "XR2XVIJ5", "version": 1, "library": { "type": "group", "id": 2330, "name": "Computer Aided Innovation", "links": { "alternate": { "href": "https://www.zotero.org/groups/computer_aided_innovation", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/2330/items/XR2XVIJ5", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/computer_aided_innovation/items/XR2XVIJ5", "type": "text/html" } }, "meta": { "createdByUser": { "id": 7918, "username": "haguayo73", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/haguayo73", "type": "text/html" } } }, "lastModifiedByUser": { "id": 32742, "username": "beloglazov", "name": "Anton Beloglazov", "links": { "alternate": { "href": "https://www.zotero.org/beloglazov", "type": "text/html" } } }, "creatorSummary": "Goldberg", "parsedDate": "2002", "numChildren": 0 }, "data": { "key": "XR2XVIJ5", "version": 1, "itemType": "book", "title": "The Design of Innovation: Lessons from and for Competent Genetic Algorithms", "creators": [ { "creatorType": "author", "firstName": "David Edward", "lastName": "Goldberg" } ], "abstractNote": "", "series": "", "seriesNumber": "", "volume": "", "numberOfVolumes": "", "edition": "", "date": "2002", "publisher": "Springer", "place": "", "originalDate": "", "originalPublisher": "", "originalPlace": "", "format": "", "numPages": "272", "ISBN": "1402070985", "DOI": "", "citationKey": "", "url": "", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "The Design of Innovation", "language": "", "libraryCatalog": "Google Books", "callNumber": "0737", "rights": "", "extra": "", "tags": [ { "tag": "genetic algorithms" } ], "collections": [], "relations": {}, "dateAdded": "2009-06-26T05:43:31Z", "dateModified": "2011-06-17T06:05:04Z" } }, { "key": "XK2EMQK7", "version": 1, "library": { "type": "group", "id": 2330, "name": "Computer Aided Innovation", "links": { "alternate": { "href": "https://www.zotero.org/groups/computer_aided_innovation", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/2330/items/XK2EMQK7", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/computer_aided_innovation/items/XK2EMQK7", "type": "text/html" } }, "meta": { "createdByUser": { "id": 7918, "username": "haguayo73", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/haguayo73", "type": "text/html" } } }, "lastModifiedByUser": { "id": 32742, "username": "beloglazov", "name": "Anton Beloglazov", "links": { "alternate": { "href": "https://www.zotero.org/beloglazov", "type": "text/html" } } }, "creatorSummary": "Khomenko and Guio", "parsedDate": "2007", "numChildren": 0 }, "data": { "key": "XK2EMQK7", "version": 1, "itemType": "conferencePaper", "title": "OTSM Network of Problems for representing and analysing problem situations with computer support", "creators": [ { "creatorType": "author", "firstName": "Nicolai", "lastName": "Khomenko" }, { "creatorType": "author", "firstName": "De", "lastName": "Guio" } ], "abstractNote": "This paper presents a method for increasing the level of formalization of the description of a problem situation and obtaining a “big picture” of the problem situation in order to be solved by TRIZ and OTSM instruments.

Despite its centrality as a cognitive phenomenon, research in emergence currently lacks a comprehensive theoretical foundation. A broadened view of design emergence that adds to the perceptual phenomenon of shape emergence in reflecting the way the design domains are conceptualized is proposed. An expanded theory of emergence in which visual cognition plays an important role is presented. Beginning with an attempt to broaden the perceptual perspectives of shape emergence, the process of cognitive emergence is defined. The duality of related perceptual and cognitive components provides a working basis for conceptualizing visual emergence in design. Antithetical to the idea of accidental emergence, it is proposed that emergence is guided and anticipated. We claim that it is the re-cognition of visual shapes and images in design that enables emergence. This kind of guidance function in emergence is termed ‘anticipated emergence’.

In those cases, the obtained solution is highly sensitive to the weight vector used in the scalarization process and demands that the user have knowledge about the underlying problem. Moreover, in solving multiobjective problems, designers may be interested in a set of Pareto-optimal points, instead of a single point. Since genetic algorithms (GAs) work with a population of points, it seems natural to use GAs in multiobjective optimization problems to capture a number of solutions simultaneously. Although a vector evaluated GA (VEGA) has been implemented by Schaffer and has been tried to solve a number of multiobjective problems, the algorithm seems to have bias toward some regions. In this paper, we investigate Goldberg's notion of nondominated sorting in GAs along with a niche and speciation method to find multiple Pareto-optimal points simultaneously. The proof-of-principle results obtained on three problems used by Schaffer and others suggest that the proposed method can be extended to higher dimensional and more difficult multiobjective problems.

First, a general introduction to evolutionary computation is presented and recent developments in this field are briefly described. Next, the field of evolutionary design is introduced and its relevance to structural design is explained. Further, the issue of creativity/novelty is discussed and possible ways of achieving it during a structural design process are suggested. Current research progress in building engineering systems’ representations, one of the key issues in evolutionary design, is subsequently discussed. Next, recent developments in constraint-handling methods in evolutionary optimization are reported. Further, the rapidly growing field of evolutionary multiobjective optimization is presented and briefly described. An emerging subfield of coevolutionary design is subsequently introduced and its current advancements reported. Next, a comprehensive review of the applications of evolutionary computation in structural design is provided and chronologically classified.

The objectives may be\nconflicting and noncommensurable, and the technique can deal\nwith minimization and maximization problems (or a mixture of\nboth). The optimum, in the min-max sense, gives a solution that\ntreats all the objectives on terms of equal importance, and presents\nthe advantage of being very efficient and easy to implement.\nFurthermore, when the min-max approach is combined with the\nweighting method, we can generate the set of Pareto\n(nondominant) solutions for both convex and nonconvex\nproblems. Taking advantage of the floating point representation\nused for the GA, we could solve design problems that involve a\nmix of continuous, discrete and integer design variables.

With the first the optimal distribution of an assigned mass is found using an approach based on homogenisation theory, that seeks in which elements of a meshed domain it is present mass; with the second the discontinuous boundaries are smoothed. The problem of the optimal topology search has an ON/OFF nature and has suggested the employment of genetic algorithms. Thus in this paper a genetic algorithm has been developed, which uses as design variables, in the topology optimisation, the relative densities (with respect to effective material density) 0 or 1 of each element of the structure and, in the shape one, the coordinates of the keypoints of changeable boundaries constituted by curves. In both the steps the aim is that to find the variable sets producing the maximum stiffness of the structure, respecting an upper limit on the employed mass. The structural evaluations are carried out with a FEM commercial code, linked to the algorithm. Some applications have been performed and results compared with solutions reported in literature.
