— Throughput performance of the IEEE 802.11 Distributed Coordination Function (DCF) is very sensitive to the number n of competing stations. The contribute of this paper is threefold. First, we show that n can be expressed as function of the collision probability encountered on the channel; hence, it can be estimated based on run-time measurements. Second,(More)
BACKGROUND Few studies have attempted to delineate the clinical profile of multiple Sclerosis (MS) among people of Asia. This study sought to identify the characteristics of early-onset Multiple Sclerosis (EOMS) comparison to adult-onset form (AOMS) in Isfahan, IRAN. METHODS This prospective study was conducted on 104 youths with multiple sclerosis(More)
— In this study, we aim to obtain " natural groupings " of 151 local non-government organizations and institutions mentioned in a news archive of 77,000 articles spanning a decade (May 1999 to Jan 2010) from Indonesia. One of our goals is to enhance our understanding of counter-radical movements in critical locations in the Muslim world. We present(More)
In this paper, we utilize feature extraction and model-fitting techniques to process the rhetoric found in the web sites of 23 Indonesian Islamic religious organizations to profile their ideology and activity patterns along a hypothesized radical/counter-radical scale, and present an end-to-end system that is able to help researchers to visualize the data(More)
In this paper we examined the broadband fixed wireless access (BFWA) systems by coherent and non-coherent detection using M-ary PSK with Gray code. A closed form for the exact symbol error rate and bit error rate (BER) of M-ary PSK is presented. We show through analysis the physical limitations of the BFWA channels over different values of M (2,4,8,16,32)(More)

Arterial hypertension is a major risk factor that can lead to complication of peripheral vascular disease due, in part, to endothelial dysfunction. Because sodium nitrite (SN) can be converted to nitric oxide (NO), which counteracts endothelial dysfunction, we explored the effect of nitrite on neovascularization following hind limb ischemia in different(More)

An analytical model for the bit error rate with different values of M-ary quadrature amplitude modulation (M-QAM) for broadband fixed wireless access (BFWA) is presented. The expressions/relations are derived and investigated for different values of M: 4, 8, 16, 32, 64, 128, and 256 to evaluate conditional probability of error, bit error probability and(More)
