TL;DR: In this article, an automatic approach for characterization and categorization of historical book pages is presented, which is based on the use of texture and graph algorithms to provide a rich and holistic description of the layout and content of the analyzed book pages.
Abstract: Over the last few years, there has been tremendous growth in digitizing collections of cultural heritage documents. Thus, many challenges and open issues have been raised, such as information retrieval in digital libraries or analyzing page content of historical books. Recently, an important need has emerged which consists in designing a computer-aided characterization and categorization tool, able to index or group historical digitized book pages according to several criteria, mainly the layout structure and/or typographic/graphical characteristics of the historical document image content. Thus, the work conducted in this thesis presents an automatic approach for characterization and categorization of historical book pages. The proposed approach is applicable to a large variety of ancient books. In addition, it does not assume a priori knowledge regarding document image layout and content. It is based on the use of texture and graph algorithms to provide a rich and holistic description of the layout and content of the analyzed book pages to characterize and categorize historical book pages. The categorization is based on the characterization of the digitized page content by texture, shape, geometric and topological descriptors. This characterization is represented by a structural signature. More precisely, the signature-based characterization approach consists of two main stages. The first stage is extracting homogeneous regions. Then, the second one is proposing a graph-based page signature which is based on the extracted homogeneous regions, reflecting its layout and content. Afterwards, by comparing the different obtained graph-based signatures using a graph-matching paradigm, the similarities of digitized historical book page layout and/or content can be deduced. Subsequently, book pages with similar layout and/or content can be categorized and grouped, and a table of contents/summary of the analyzed digitized historical book can be provided automatically. As a consequence, numerous signature-based applications (e.g. information retrieval in digital libraries according to several criteria, page categorization) can be implemented for managing effectively a corpus or collections of books. To illustrate the effectiveness of the proposed page signature, a detailed experimental evaluation has been conducted in this work for assessing two possible categorization applications, unsupervised page classification and page stream segmentation. In addition, the different steps of the proposed approach have been evaluated on a large variety of historical document images.

TL;DR: In this article, the authors present a layout-design support apparatus, in which the result of a correction with respect to a layout pattern and the verification result of the correction can be confirmed by the layout pattern designer himself during a designing operation.
Abstract: PROBLEM TO BE SOLVED: To provide a layout-design support apparatus, in which the result of a correction with respect to a layout pattern and the verification result of the correction can be confirmed by a layout pattern designer himself during a designing operation SOLUTION: This design support apparatus which creates a reticle pattern used for a reduction projection exposure is constituted of a layout editor 1 which creates a layout pattern In addition, the apparatus is constituted of an optical proximity-effect correction(OPC) and a verification device 2 which corrects and verifies the layout pattern In addition, the apparatus is constituted of a database 3 or the like, in which the layout pattern and correction and verification data are stored The layout editor 1 can be operated by a designer through a user interface A correction and verification command is added to a menu on a screen, in order to support a function which corrects and verifies the OPC and verification device 2, in addition to a function which creates the layout pattern

TL;DR: In this article, the problem of layout flexibility in an environment affected by stochastic product flows is discussed, where the layout itself must behave efficiently under varying conditions and levels of item production.
Abstract: This paper discusses the problem of the layout flexibility problem. In an environment affected by stochastic product flows, identifying the optimal layout acquires particular relevance, as the layout itself must behave efficiently under varying conditions and levels of item production. This work advocates the need for modifying the parameters usually proposed in literature to optimize the physical location of the workstations on the shopfloor. These parameters will consider not only the average value of the part flows between two generic machines, but also the standard deviation of the flows themselves. With such quantities, it is possible to design layouts which guarantee a more regular performance, in terms of material handling requests when volumes and demand mix change over time (market dynamics). Therefore, this study concerns the formulation of stability layout indices which are based on the flow distributions between each machine pair (i.e. as a function of the route-sheets and the demand distribut...

TL;DR: An evolutionary approach that enables the automatic design of modular residential homes in mass customized production and will allow for future owners to acquire houses fitting their exact needs at affordable prices, improving the quality of living while simultaneously complying with a language of design.
Abstract: This work presents an evolutionary approach that enables the automatic design of modular residential homes in mass customized production. Given a set of modular placement rules for the design, the formal problem can be viewed as a two-dimensional single large object placement problem with fixed dimensions and additional positioning constraints. This formulation results in the search of a floor plan layout constrained by dimensional and positional restrictions over a combinatorial size search space. A genetic algorithm strategy for the automation of floor plan design was implemented and shown to deliver the required design solution layouts. The layouts, when embedded into a proper graphical interface system will allow for future owners to acquire houses fitting their exact needs at affordable prices, improving the quality of living while simultaneously complying with a language of design.

TL;DR: In this paper, the authors consider different criteria in addition to cost to suggest an efficient solution for dynamic layout problem, where the layout design has a significant impact on the performance of a manufacturing or service industry system.
Abstract: The main characteristic of today's manufacturing environments is volatility. Under such a volatile environment some parameters like demand is not stable. To operate efficiently under such environments, the facilities must be adaptive to change production requirements. From a layout point of view, this situation requires the solution of the dynamic layout problem (DLP). Layout design has a significant impact on the performance of a manufacturing or service industry system. So designing an efficient layout considering different criteria is interesting for researchers. But dynamic layout problems usually are solved just considering cost criterion. This paper is to consider different criteria in addition to cost to suggest an efficient solution for dynamic layout problem. To this purpose, at first we use classic models for DLP 1 to
