We consider scheduling policies for maxmin fair allocation of bandwidth in wireless adhoc networks. We formalize the maxmin fair objective under wireless scheduling constraints. We propose a fair scheduling which assigns dynamic weights to the flows such that the weights depend on the congestion in the neighborhood and schedule the flows which constitute a maximum weighted matching. It is possi...

Wireless local area networks (WLAN) are gaining popularity at an unprecedented rate, at home, at work, and in public hot spot locations. As these networks become ubiquitous and an integral part of the infrastructure, they will be increasingly used for multi-media applications. There is limited Quality of Service (QoS) support in WLANs and this will become an impediment in deploying multi-media ...

Firms to Suharto lost substantial market share following his resignation. Industries in which family firms larger during tenure exhibited weak improvements broader ...

The purpose of this study was to establish the validity and reliability of a hydrostatic weighing method using total lung capacity (measuring vital capacity with a respirometer at the time of weighing) the prone position, and a small oblong tank. The validity of the method was established by comparing the TLC prone (tank) method against three hydrostatic weighing methods administered in a pool....

Since the introduction of news-based policy uncertainty measure, a few studies have looked at its impact on trade flows by using panel models and aggregate data. In this paper we consider short-run long-run response 61 2-digit U.S. exporting industries to Korea 49 Korean measures Korea. We find that both effects exports almost one-third in either direction. long run, however, while nine (with s...

The fall of labor’s share of GDP in the United States and many other countries in recent decades is well documented but its causes remain uncertain. Existing empirical assessments of trends in labor’s share typically have relied on industry or macro data, obscuring heterogeneity among firms. In this paper, we analyze micro panel data from the U.S. Economic Census since 1982 and international so...

Nonetheless, at nearly all levels of US society the res...
