Driven by a trend towards renewable forms of generation, in particular wind, the nature of power system operation is changing. With respect to wind power, the uncertainty of the wind becomes an issue which must be considered. Through the use of wind forecasting, this uncertainty may be managed. The error inherent in forecasting will impact system reliability and cost as will inaccuracies in ass...

Error-resilient variable length codes (VLCs) have been proposed to counter bit errors over error-prone channels. In this work we establish a linkage between channel coding and watermarking by observing that watermark bits are, in effect, intentional bit errors. Using a recently introduced resynchronizing VLC, we have developed a compressed-domain watermarking algorithm where the inherent errorr...

One of the remarkable challenges about Wireless Sensor Networks (WSN) is how to transfer the collected data efficiently due to energy limitation of sensor nodes. Network coding will increase network throughput of WSN dramatically due to the broadcast nature of WSN. However, the network coding usually propagates a single original error over the whole network. Due to the special property of error...

Stochastic computing is an old and unconventional computing technique that is finding promising new applications in imageprocessing and the handling of complex error-correcting codes. Stochastic circuits offer an alternative to conventional digital circuits because of their extremely small size and inherent noise tolerance. They are also well-suited to meeting the requirements of emerging nanos...

Head-mounted eye tracking has significant potential for mobile gaze-based interaction with ambient displays but current interfaces lack information about the tracker’s gaze estimation error. Consequently, current interfaces do not exploit the full potential of gaze input as the inherent estimation error can not be dealt with. The error depends on the physical properties of the display and const...

DESPITE THE NUMEROUS procedures available for the determination of uric acid, their clinical use remains subject to considerable error. A simple precise method for routine clinical use is desirable since determination of the level of serum uric acid is an important criterion for the diagnosis of gout. Excellent critical reviews of the available methods have been published (1, 2, 3). The current...
