Whispers are an important secondary vocal communications mechanism that can be necessary for communicating private information and which are an integral aspect of natural human-to-human dialogue. Furthermore, they may be the primary vocal communications method of those suffering from certain forms of aphonia, such as laryngectomees. This paper considers the(More)
Whispering is a natural, unphonated, secondary aspect of speech communications for most people. However, it is the primary mechanism of communications for some speakers who have impaired voice production mechanisms, such as partial laryngectomees, as well as for those prescribed voice rest, which often follows surgery or damage to the larynx. Unlike most(More)
Geometric distortions are simple and effective attacks rendering many watermarking methods useless. They make detection and extraction of the embedded watermark difficult or even impossible by destroying the synchronization between the watermark reader and the embedded watermark. In this paper, we propose a blind content-based image watermarking scheme(More)
Whispers are a common and necessary secondary vocal communications mechanism for natural human-to-human dialogue. They are also the primary communications mechanism for many suffering from aphonia, such as laryngectomees. For typical speakers, whispering is a predominantly contextual activity, prompted by either the sensitive nature of information being(More)
The design of monitoring and predictive alarm systems is necessary for successful overhead power transmission line icing. Given the characteristics of complexity, nonlinearity, and fitfulness in the line icing process, a model based on a multivariable time series is presented here to predict the icing load of a transmission line. In this model, the time(More)
