Motivated by channel measurements in different indoor locations we will show that the WLAN indoor MIMO channel is characterized by few dominant transmission paths mainly corresponding to the LOS path and some strong reflections. In the contrary to the common statistical flat Rayleigh fading channel model we will explain that the WLAN channel is widely deterministic and frequency selective. Furt...

one of the most important parameters in evaluating a watermarking algorithm is its capacity. generally, watermarking capacity is expressed by bits per pixel (bpp) unit measure. but this measure does not show what the side effects would be on image quality, watermark robustness and capacity. in this paper we propose a three dimensional measure named capacity surface which shows the effects of ca...

This paper contains a construction for independent sets in the powers of the complements of odd cycles. In particular, we show that α ( C 2 2n+3 ) ≥ 22n + 1. It follows that for n ≥ 0 we have Θ(C2n+3) > 2, where Θ(G) denotes the Shannon capacity of graph G.

The Women's Health Program at the University of Michigan was established in 1993 and has developed into a successful, federally supported program that links clinical research and education activities across the University. It has focused on human resource capacity building, sustainable financial support and infrastructure, and adaptability to change and opportunities. Widely accepted standards,...

Public Health emphasizes the plurality of the determinants of health of individuals, families and communities. Nutrition, as a major determinant of health, is itself influenced by a multitude of determinants that are under the purview of several agencies. Thus, inter-sectoral collaboration among the relevant agencies is imperative for promoting optimal health and nutrition such a partnership is...

Abstract—In this paper we consider the identification (ID) via multiple access channels (MACs). In the general MAC the ID capacity region includes the ordinary transmission (TR) capacity region. In this paper we discuss the converse coding theorem. We estimate two types of error probabilities of identification for rates outside capacity region, deriving some function which serves as a lower bou...
