In this paper, we present a case study of applying visual analytics methods to explore a dynamic social network. The visualization and analysis of this kind of data is challenging because of its relational and temporal nature. We illustrate a method and its prototypical implementation that integrate: the combination of three views based on node-link diagrams, a dynamic layout, the visualization...

Dynamic comparators are used in high speed analog to digital converters. In this paper low voltage, low power dynamic comparators are designed in 130 nm technology and the analysis of the power consumption and delay will be presented. Based on the presented analysis, a new dynamic comparator is proposed. By using power gating technique and adding few transistors, the positive feedback during th...

We adapt multilevel, force-directed graph layout techniques to visualizing dynamic graphs in which vertices and edges are added and removed in an online fashion (i.e., unpredictably). We maintain multiple levels of coarseness using a dynamic, randomized coarsening algorithm. To ensure the vertices follow smooth trajectories, we employ dynamics simulation techniques, treating the vertices as poi...

SUNG-EUI YOON: Interactive Visualization and Collision Detection using Dynamic Simplification and Cache-Coherent Layouts (Under the direction of Dinesh Manocha) Recent advances in model acquisition, computer-aided design, and simulation technologies have resulted in massive databases of complex geometric models consisting of more than tens or hundreds of millions of triangles. In spite of the r...

introduction: the appropriate-use optimization of the limited spaces of the iranian hospitals is believed to be a crucial step towards promoting the efficiency of these healthcare centers. the issue determining the optimization patterns of the layout of units has led to a lot of efforts by researchers as it increases the efficiency of the hospitals through patients’ improvement, changing the lo...

Metal price is one of the most important parameters in the calculation of cut- off grade. The cut- off grade has the main role in determination of mine layout. Mine layout actuates mineable reserve, mine life and economic profitability. Not considering the uncertainty in metal prices can lead to a non-optimal layout. In this paper optimum underground mine layout is determined by expected utilit...
