In this paper the HDWTSVD algorithm to encode monochromatic images is proposed. The algorithm combines DWT and SVD techniques. The input image is divided into tiles of 64x64 pixels. A criterion based on the average standard deviation of 8x8 subblocks is used to choose DWT or SVD. If the tile exhibits a high average standard deviation, it is compressed by using SVD otherwise by DWT. Eigenvalues ...

Media coverage suggested that this riot was a manifestation of the campaign against the opening of a Tesco supermarket in the area. Footage later emerged on YouTube, which appeared to support claims by local residents that the violence was caused by heavy-handed police tactics rather than t...

Input/output (I/O) operations can represent a significant proportion of the run-time when large scientific applications are run in parallel. Although there have been advances in the form of file-format libraries, file system design and I/O hardware, a growing divergence exists between the performance of parallel file systems and compute processing rates. In this paper we utilise RIOT, an input/...

In this paper we describe the development of a decision support system for crowd control. Decision support is provided by suggesting a control strategy needed to control a specific current riot situation. Such control strategies consist of deployment of several police barriers with specific barrier positions and barrier strengths needed to control the riot. The control strategies are derived fo...

For 9 hours on a hot Sunday afternoon in Sydney, Australia, police in riot gear battled 200 Aboriginal youths (Chulov, Warne-Smith, & Colman, 2004). Bricks, bottles, and firecrackers rained down on the police, 40 of whom were injured during the melee.
