This paper presents a novel real-time algorithm to integrate internal and external labels of arbitrary size into 3D visualizations. Moreover, comprehensive dynamic content can be displayed in annotation boxes. Our system employs multiple metrics in order to achieve an effective and aesthetic label layout with adjustable weights. The layout algorithm employs several heuristics to reduce the sear...

An improved genetic algorithm for the dynamic layout problem, based on a paper that was published in this journal, is formulated and tested in this research. Our genetic algorithm differs from the existing implementation in three ways: first, we adopt a different crossover operator, second, we use mutation, and third, we use a new generational replacement strategy to help increase population di...

We propose a heuristic for maintaining dynamic hierarchical graph layouts. The heuristic is an on-line interpretation of the static layout algorithm of Sugiyama, Togawa and Toda. It incorporates topological and geometric information with the objective of making layout animations that are both incrementally stable and readable through long editing sequences. We present measurements of an experim...

The design of automatic layout algorithms for single graphs is a well established field, and some recent studies show how these algorithms affect human understanding. By contrast, layout algorithms for graphs that change over time are relatively immature, and few studies exist to evaluate their effectiveness empirically. This paper presents two new dynamic graph layout algorithms and empirical ...

As networks and their structure have become a major field of research, a strong demand to visualize these networks has emerged. We address this challenge by formalizing the well established spring layout in terms of dynamic equations. We thus opening up the design space for new algorithms. Drawing from the knowledge of systems design, we derive a layout algorithm that remedies several drawbacks...

A dynamic and optimal shop floor design, modelling and implementation is key to achieving successful Fractal Manufacturing System (FrMS). To build adaptive and fault-tolerant fractal layout, attention is paid to issues of shop floor planning, function layout, determination of capacity level, cell composition planning and flow distances of products. A full fledged FrMS. layout is multi-functiona...

This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...
