generally, authentication in vehicular adhoc net-works (VANETs) used Public Key Infrastructure to check the Message integrity and the of message senders. The problems considered in the authentication schemes are the level of security and computational efficiency in verification processes. Most of existing schemes focus mainly on the security and privacy of VANET information. However, these sche...

The hospital experience can be disempowering and disorientating. Patients are deprived of sleep deprivation and exposed to constant noise, frequent interruptions, an unfamiliar environment filled with changing health professionals and ancillary staff, as well as medications often fraught with physical or psychoactive side-effects. These conditions often lead to discomfort and anxiety, and commo...

This paper presents the CAWE framework for the context-aware management of applications based on the composition of Web Services in complex workflows. We introduce a representation of context-dependent activities based on an abstraction hierarchy which supports the specification of synthetic and clear workflows. Moreover, we propose a framework architecture which enriches the capabilities of a ...

The wavelet based denoising has proven its ability to denoise the bearing vibration signals by improving the signal-to-noise ratio (SNR) and reducing the root-mean-square error (RMSE). In this paper seven wavelet based denoising schemes have been evaluated based on the performance of the Artificial Neural Network (ANN) and the Support Vector Machine (SVM), for the bearing condition classificati...

Carotenoids and their metabolites are essential factors for the maintenance of important life processes such as photosynthesis. Animals cannot synthesize carotenoids de novo, they must obtain them via their food. In order to make intensive animal husbandry possible and maintain human and animal health synthetic nature identical carotenoids are presently commercially available at the multi-tonne...
