Let be a random sample from a normal distribution with unknown mean and known variance The usual estimator of the mean, i.e., sample mean is the maximum likelihood estimator which under squared error loss function is minimax and admissible estimator. In many practical situations, is known in advance to lie in an interval, say for some In this case, the maximum likelihood estimator...

In this paper, we study the geometry induced by Fisher-Rao metric on parameter space of Dirichlet distributions. We show that is geodesically complete and has everywhere negative sectional curvature. An important consequence curvature for applications Fr{\'e}chet mean a set distributions uniquely defined in geometry.

Multiple antennas arrays combined with high carrier frequencies play a key role in wireless networks for communications but also localization and sensing applications. To understand the fundamental limits of electromagnetically large antenna localization, this paper combines wave propagation theory estimation theory, computes Cramér-Rao Bound (CRB) source position on basis three Cartesian compo...

Acute renal failure can result from many conditions, in which artery stenosis (RAS) or obstruction (RAO) be corrected with appropriate interventional surgical procedures. The directly depicted currently available ultrasound (US) scanners. Therefore, we determine if there is RAS RAO patients poor function using US. However, are few reports about the utility of US excluding obstruction. purpose t...

nature neuroscience • volume 2 no 1 • january 1999 79 Neurons that respond optimally to line segments of a particular length were first reported in early studies of the cat and monkey visual cortex1,2. These neurons, which are especially abundant in cortical layers 2 and 3, have the curious property of endstopping (or end-inhibition): a vigorous response to an optimally oriented line segment is...
