After a decade of extensive research on application-specific wireless sensor networks (WSNs), the recent development of information and communication technologies make it practical to realize new WSNs paradigm known as software-defined sensor networks (SDSNs). SDSNs are able to adapt to various application requirements and to fully explore the(More)
The multidimensional diffusion model for computer animation of diffuse ink painting opens up a new dimension in painting. In diffuse painting final image is a result of ink diffusion in absorbent paper. A straightforward diffusion model however is unable to provide very specific features of real diffuse painting. In particular , it can not explain the(More)
PURPOSE Among diabetes mellitus type 2 (DM2) patients, the frequency of cognitive dysfunction is higher and the relative risk of Alzheimer's disease (AD) is approximately twice that of nondiabetics. Cognitive impairment symptoms of AD are induced by limbic system dysfunction, and an early-stage AD brain without dementia has the potential for atrophy in the(More)
We propose a software-defined wireless sensor network system whose behavior can be redefined even after deployment by the injection of sensor node roles by means of wireless network communications. Two main technologies are used to develop this system, role generation and delivery mechanism, and a reconfigurable wireless sensor network with many(More)
This letter introduces a novel method of sequence construction having a zero-correlation zone. The cross-correlation function and the side-lobe of the auto-correlation function of the proposed sequence set is zero for the phase shifts within the zero-correlation zone. The proposed zero-correlation zone sequence set can be generated from an arbitrary perfect(More)
