Bionic design and verification of high-precision machine tool structures

Abstract: Highly stiff and lightweight machine tool structures are very important for improving machining accuracy. How to reasonably arrange stiffeners is one of the problems that designers must solve to achieve required structural performances. This paper presents a practical approach for stiffener layout design, which is inspired by the adaptive growth phenomenon observed in nature. Firstly, a mathematical model is built to provide theoretical basis for the adaptive growth of stiffeners to the applied load. Then a corresponding algorithm is developed to realize the generation of stiffener layout, during which the growth rates are determined by the generalized heights of stiffeners and the growth directions by branching and degenerating operations. When applying the approach to redesign an actual machine tool bed structure, a simple spring model is introduced, which can greatly reduce computation cost by transforming the 3D stiffener layout design problem into a 2D one. Numerical and experimental results show the stiffness enhancement, and thus, the applicability and validity of the approach are proved.

Building the Design

Abstract: This chapter walks you through the major front end development tasks for building your visual design, including optimizing images, creating CSS, master pages, page layouts, and other techniques to transform the approved visual designs into a functional SharePoint 2010 branded site. Building the design takes place within the development phase after the visual designer has received final approval of the visual design, as shown in step 7 of Figure 6-1. (This 7-step process was first introduced in Chapter 2.)

Two algorithms for automatic document page layout

Abstract: This paper describes two approaches to the problem of automatically placing document items on pages of some output device. Both solutions partition the page into regions where each item is to be placed, but work on different input data according to the application: One approach assumes that previously defined rectangular items are to be placed freely on the page (as in a sales brochure), whereas the second approach places free-form items on pages divided into columns (as in a newspaper). Moreover, both approaches try to preserve the reading order provided by the input and use all available area on the page. The algorithms implementing those approaches and based on recursive page division are presented, as well as test results, possible changes and research directions.

Concurrent cell formation and layout design using scatter search

Abstract: Two key decisions in designing cellular manufacturing systems are cell formation and layout design problems. In the cell formation problem, machine groups and part families are determined while in the facility layout problem the location of each machine in each cell (intra-cell layout) and the location of each cell (inter-cell layout) are decided. Owing to the fact that there are interactions between two problems, cell formation and layout design problem must be tackled concurrently to design a productive manufacturing system. In this research, two problems are investigated concurrently. Some important and realistic factors such as inter-cell layout, intra-cell layout, operations sequence, part demands, batch size, number of cells, cell size, and variable process routings are incorporated in the problem. The problem is formulated as a mathematical model. Three different methods are described to solve the problem: multi-objective scatter search (MOSS), non-dominated genetic algorithm (NSGA-II), and the e-constraint method. The methods are employed to solve nine problems generated and adopted from the literature. Sensitivity analysis is accomplished on the parameters of the problem to investigate the effects of them on objective function values. The results show that the proposed MOSS algorithm performs better than NSGA-II and produces better solutions in comparison to multi-stage approaches.

Automatic article extraction in old newspapers digitized collections

Abstract: We present a complete method for article segmentation in old newspapers, which deals with complex layouts analysis of degraded documents. The designed workflow can process large amounts of documents and generates digital objects in METS/ALTO format in order to facilitate the indexing and the browsing of information in digital libraries. The analysis of the document image is performed by a two stages scheme. Pixels are labeled in a first stage with a Conditional Random Field model in order to intent to label the areas of interest with a low logical level. Then this first logical representation of the document content is analyzed in a second stage to get a higher logical representation including article segmentation and reading order. This top-level structural analysis relies on the generation of an article separation grid applied recursively on the document image, allowing analyzing any type of Manhattan page layout, even for complex structures with multiple columns and overlapping entities. This method which benefits from both a local analysis using a probabilistic model trained using machine learning procedures, and a more global structural analysis using recursive rules, is evaluated on a dataset of daily local press document images covering several time periods and different page layouts, to prove its effectiveness.
