This paper proposes an efficient algorithm to compress the cubes in the progress of the parallel data cube generation. This low overhead compression mechanism provides block-by-block and record-by-record compression by using tuple difference coding techniques, thereby maximizing the compression ratio and minimizing the decompression penalty at run-time. The experimental results demonstrate that...

Space time cube representation is an information visualization technique where spatiotemporal data points are mapped into a cube. Fast and correct analysis of such information is important in for instance geospatial and social visualization applications. Information visualization researchers have previously argued that space time cube representation is beneficial in revealing complex spatiotemp...

We present the generalized space-time cube, a descriptive model for visualizations of temporal data. Visualizations are described as operations on the cube, which transform the cube’s 3D shape into readable 2D visualizations. Operations include: extracting subparts of the cube, flattening it across space or time, or transforming the cube’s geometry and content. We introduce a taxonomy of elemen...

We review a range of temporal data visualization techniques through a new lens, by describing them as series of operations performed on a conceptual space-time cube. These operations include extracting subparts of a space-time cube, flattening it across space or time, or transforming the cube’s geometry or content. We introduce a taxonomy of elementary space-time cube operations, and explain ho...

Squaring the Circle is a famous geometry problem going all way back to ancient Greeks. It great quest of constructing square with same area as circle using compass and straightedge in finite number steps. Since it was proven that ⇡ transcendental 1882, task has been considered impossible. Here, we will show possible Square space-time. not Euclidean space alone, but fully space-time, after live ...
