An accurate estimation of network performance is critical for the success of optical networks design. Traffic modeling and availability modeling for optical network are at heart of optical network design. Traffic models and availability models need to be accurate and able to capture the statistical characteristics of the actual traffic and the ability of a network to sustain failures. However, ...

conclusions geographic accessibility of pharmacies at night and on holidays has to be addressed by provincial health policymakers. materials and methods the analysis was based on straight-line distance measurements. we considered 150, 300, 450, 600, and 750 m for pedestrians, and 1, 2, and 3 km for driving accessibility as the acceptable distances. we calculated the number and percentage of hou...

Although lymphatic filariasis is known to have been endemic in Haiti since at least the mid 1700s, a national filariasis survey has never been conducted. As a first step in the national program to eliminate filariasis, we collected blood in January-April 2001 from 50-250 school children (6-11 years old) in all 133 communes of the country using an adaptation of the lot quality assurance sampling...

Average consanguinity (alpha) of 20 large regional or national samples derived from Roman Catholic Dispensations or state archives shows a strong negative relationship with latitude (r = -0.738; P less than 0.001) which seems best explained by cultural-historical factors. Isolates show no such pattern and are more variable in their inbreeding levels. Two-way analysis of variance shows the sampl...

In order to address classic questions about democratic representation in countries with winner-take-all electoral districts, it is necessary to understand the distribution of political preferences across districts. Recent formal theory literature has contributed new insights into how parties choose platforms in countries with a continuum of heterogeneous districts. Meanwhile, increases in surve...

We used ecologic niche modeling of outbreaks and sporadic cases of filovirus-associated hemorrhagic fever (HF) to provide a large-scale perspective on the geographic and ecologic distributions of Ebola and Marburg viruses. We predicted that filovirus would occur across the Afrotropics: Ebola HF in the humid rain forests of central and western Africa, and Marburg HF in the drier and more open ar...

There are projected shortages in the supply of dentists in Australia, and these shortages are likely to be more evident in areas outside of capital cities. This report explores the geographic distribution of dentists and the differences in supply of dental services to regions defined by remoteness. Remoteness may be thought as the travel time to obtaining goods and services. Australian Statisti...
