Low power realization of video applications on embedded cores is described. Code transformations are applied to reduce the data memory power consumption. The transformed code indicates a power efficient data memory architecture while transformations move the main part of memory accesses from larger memories (possibly off-chip) to smaller ones (on-chip). The effect of transformations on performa...

We present a new method for computing temporal aggregation that uses a multi-dimensional index. The novelty of our method lies in mapping the start time and end time of a temporal tuple to a data point in a two-dimensional space to be stored in a two-dimensional index and in calculating the temporal aggregates through a temporal join between the data in the index and the base intervals (defined...

The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...

Software applications are inevitably concerned with data integrity, whether the data is stored in a database, files, or program memory. An integrity guard is code executed before a data update is performed. The guard returns “true” just if the update will preserve data integrity. The problem considered here is how integrity guards can be produced automatically from data integrity constraints. W...
