A common approach to automatic quad layout generation on surfaces is to, in a first stage, decide the positioning of irregular vertices, followed by finding sensible edges connecting these vertices and partitioning surface into quadrilateral patches second stage. While this two-step reduces problem's complexity, separation also limits result quality. In worst case, set fixed stage without consi...

Previous work has demonstrated the existence of keyboard layouts capable of maintaining consistent fingerings across a parameterised family of tunings. This paper describes the general principles underlying layouts that are invariant in both transposition and tuning. Straightforward computational methods for determining appropriate bases for a regular temperament are given in terms of a row-red...

In this paper, we present new solutions for the interactive modeling of city layouts that combine the power of procedural modeling with the flexibility of manual modeling. Procedural modeling enables us to quickly generate large city layouts, while manual modeling allows us to hand-craft every aspect of a city. We introduce transformation and merging operators for both topology preserving and t...

lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. in a more basic term, more value with less work. since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...

This paper describes a knowledge-based system for automatically synthesizing integrated circuit layouts for NMOS cells. The desired cell layouts are specified in terms of their general structural and functional characteristics. From these initial specifications, the system produces correct and CoriJpact cell layouts. The system performs this task by generating plan steps at different levels of ...

With the advent of information systems and the recent developments in computing technology, traditional manufacturing systems are fast becoming obsolete. A new generation of factories is being designed with cellular or linked-cell manufacturing systems. This recent shift from traditional to cellular manufacturing system has necessitated the redesign of the factory and its layout. Traditional pr...

We investigate the new problem of automatic metro map layout. In general, a metro map consists of a set of lines which have intersections or overlaps. We define a set of aesthetic criteria for good metro map layouts and present a method to produce such layouts automatically. Our method uses a variation of the spring algorithm with a suitable preprocessing step. The experimental results with rea...
