The widespread applications of mobile ad hoc networks (MANET) and scarce network resources have lead to the development of many protocols in this field. The need of time is to find a protocol which makes efficient use of resources and improves the overall performance of the network. This paper focuses on enhancing the performance of ad hoc on demand(More)
Audio watermarking has been proved as a powerful tool against illegal manipulation of audio products. It is generally used as a multimedia copyright protection tool. In this paper, we propose an audio watermarking algorithm based on two mathematical functions: Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD). These algorithms(More)
In this paper, we present a novel algorithm for robust audio watermarking in image using wavelet transform based on an image texture. The algorithm is based on decomposition of images using Daubechies wavelet basis. The technique proposed in this paper resolves the problem of severe distortion caused by watermarking audio in an image by developing a scaling(More)
Physical attractiveness is an important cue for social interaction. Psychology studies have long shown that physical attractiveness can elicit positive personality attributions as well as positive behaviour towards other people. This effect is explained by the attractiveness stereotype. In this paper, we investigate whether this stereotype apply to the(More)
As interest in applying cognitive load theory (CLT) to the study and design of pedagogic and technological approaches in healthcare simulation grows, suitable measures of cognitive load (CL) are needed. Here, we report a two-phased study investigating the sensitivity of subjective ratings of mental effort (SRME) and secondary-task performance (signal(More)
BACKGROUND Tens of thousands of cardiac and vascular surgeries (CaVS) are performed on seniors in Canada and the United Kingdom each year to improve survival, relieve disease symptoms, and improve health-related quality of life (HRQL). However, chronic postsurgical pain (CPSP), undetected or delayed detection of hemodynamic compromise, complications, and(More)
On December 6, 2013, 23andMe stopped marketing direct-to-consumer (DTC) 1 disease-predictive genetic testing to comply with the FDA's directive (1). Although the FDA's action was intended to protect the American public from questionable disease risk predictions , we believe the agency failed to assess all the benefits of DTC testing. Despite assurances(More)
