Sizing the Horizon: The Effects of Chart Size and Layering on the Graphical Perception of Time Series Visualizations
Visualization graphical perception time series line charts, horizon graphs
2016/5/24
We investigate techniques for visualizing time series data
and evaluate their effect in value comparison tasks. We
compare line charts with horizon graphs—a space-efficient
time series visualizatio...
Hierarchical Identity Based Encryption with Constant Size Ciphertext
Constant Size Ciphertext Based Encryption
2015/8/5
We present a Hierarchical Identity Based Encryption (HIBE) system where the ciphertext consists of just three group elements and decryption requires only two bilinear map computations, independent of ...
A traitor tracing system enables a publisher to trace a pirate decryption box to one of the secret keys used to create the box. We present the first traitor tracing system where ciphertext size is "co...
Laid-Back, Touchless Collaboration around Wall-size Displays: Visual Feedback and Affordances
Touchless Gestures Visual Feedback Collaboration Wall-size Displays
2014/12/20
To facilitate interaction and collaboration around ultra-high-resolution, Wall-Size Displays (WSD), post-WIMP interaction modes like touchless and multi-touch have opened up new, unprecedented opportu...
Does Touching a Projection Augmented Model and Interacting with it using a Spatially-Coincident Device, Affect a User's Perception of its Size?
Projection Augmented models haptic Tangible User Interface
2009/12/9
A Projection Augmented model (PA model) is a novel type of display. It consists of a real physical model, onto which a computer image is projected to create a realistic looking object. PA models pro...

异构盘阵中最优Stripe Unit Size选择技术
异构盘阵 性能模型 带宽 条带单元大小
2007/11/1
缓解计算机IO子系统瓶颈的有效手段是采用磁盘阵列.配置时，SUS（Stripe Unit Size）的选择对盘阵性能的影响非常关键，而以往对异构盘阵的SUS的选择研究较少. 该文推导出了确定异构盘阵最优SUS的方程，具体工作如下：首先，该文采用close队列网络模型来描述异构盘阵负载；然后，从该模型推导出系统数据传输率解析表达式.根据该表达式和异构盘阵中设备的特性，可求出使传输率最大的SUS.最后...
