In this paper we propose an approach for Document Layout Analysis based on local correlation features. We identify and extract illustrations in digitized documents by learning the discriminative patterns of textual and pictorial regions. The proposal has been demonstrated to be effective on historical datasets and to outperform the state-of-the-art in presence of challenging documents with a la...

In this study, solutions for machinery layout with the aim of reducing transportation costs will be discussed. To do this, imperialist competitive algorithm (ICA), which is a very complicated and effective meta-heuristic algorithm is introduced. In the offered algorithm, different kinds of machinery layout are considered in single-row as country and then the best possible layout is developed ba...

This paper presents an interactive system for intelligent generation of artificial flora for graphical environments. The system operates upon simple graphical user interface allowing the user to generate and visualize plant models based on certain input parameters concerning the layout of a plant. Using the formalisms of L-systems and the subapical growth conception a central repository for sub...

Object-based CAD programming is used to take advantage of standardisation to handle the schematic design, sizing, layout and (potentially) pipe-routing for LPHW (Low Pressure Hot Water) plant rooms in buildings. From a simple specification of the plant room geometry, and the heating load in kw, our software proceeds through a number of steps. First the standard number and size of modular boiler...

Six Sigma DMAIC methodology has been applied to systematically apply lean manufacturing concepts and tools in order to improve productivity in a local company specialized in the manufacturing of safety and fire resistance metal doors, windows, and frames. In-depth analysis of the plant processes unfolded different critical processes, specifically foam injection process and sheet metal cutting p...

Sewer system design must be integrated with wastewater treatment plant design when moving towards a more sustainable urban wastewater management. This integration allows an optimization of the design of both systems to achieve a better and more cost-effective wastewater management. Hitherto integrated process design has not been an option because the tools to predict in-sewer wastewater transfo...

We describe a feature-rich conditional random field model for the extraction of conference and workshop information (e.g. name, date, location, deadline) from calls for papers (CFPs). This has applications in the automatic construction of a conference knowledge base from a collection of CFPs. Relevant information in CFPs is often contained in regions that do not contain complete, grammatical se...

This article deals with the qualitative modelling of batch production plants. The approach held is Petri net based. First a definition of a three-level net formalism is presented; the formalism extends the Valk’s approach of nets in nets in which the tokens are other nets; in this extension the lower level net handles symbolic tokens. Then a methodology for the modelling of batch processes is p...
