We propose a new method using a 3D Clifford analytic signal (CAS) approach for breast lesion segmentation of DCE-MRI data. ...
However, the massive and complex 4D spatial-temporal DCE-MRI data make the diagnosis process lengthy and error-prone. ...
We further propose a 3D Clifford temporal image (CTI) construction method by applying the CAS to the 4D spatial-temporal DCE-MRI data, which can automatically combine all the temporal information of DCE-MRI ...

We employ spatio-temporal parallelism, which combines both spatial and temporal parallelism, to provide greater flexibility to possible file access patterns. ...
Using our model, we were able to configure the spatio-temporal parallelism to design optimized read access patterns that resulted in a speedup factor of approximately 400 over traditional file access patterns ...
which obtained far greater I/O performance versus spatial parallelism. Several timing tests showed that the optimized file access patterns resulted in a factor of more than 400 speedup. ...

Community user access of a WebGIS is characterized by intensity and popularity. The requested geospatial data have the characteristics of spatial and temporal locality. ...
This paper proposed an expression for the replacement feature by balancing spatial and temporal locality as well as long-term and short-term popularity in tile access to ensure that the replacement process ...
Thus, this paper analyzed and considered the spatial locality and temporal locality of tile access and proposed a way to express the accessed hotspot popularity and its features of spatial-temporal locality ...
