This document describes the utilization of the nonconventional measurements and advanced features of IEC 61850 standard for substation automation systems, especially how sampled value sending according standard part 9-2 can be used between IEDs in mediumvoltage substation to improve the reliability and functionality of the system. Calculated results indicate improvements on availability, perfor...

This paper focuses on the task of automatic feature detection for computer-assisted fixation of hip fractures. The features of interest are the lateral cortex line, the femoral neck centre and the femoral head centre, the latter being the most challenging of all. A nonconventional “divide-and-conquer” knowledgebased approach produces more reliable and faster results than the standard global ima...

If current population trends continue and treatments that arrest or reverse Alzheimer disease (AD) are not found, the number of patients with AD in the United States is projected to increase to more than 13 million by the year 2050.1 Numbers of persons afflicted with severe cognitive impairment caused by traumatic brain injury and stroke also continue to increase. Developing effective and cost-...

We study the rate of growth of ergodic sums along a sequence (an) of times: SNf(x) = ∑ n≤N f(T nx). We characterize the maximal rate of growth and identify a number of sequences such as an = 2, along which the maximal rate of growth is achieved. We also return to Khintchine’s Strong Uniform Distribution Conjecture that the averages (1/N) ∑ n≤N f(nx mod 1) converge pointwise to ∫ f for integrabl...
