Digital road databases are widely used in many facets of our daily life. Most of these databases come with a nominal quality indication, but often more detailed quality descriptions regarding possible errors, the positional accuracy, and information on the completeness of the vector data are desirable. In this paper an approach for the quality description of road data from the Authoritative Top...

OBJECTIVES The aim of this study is to assess the sleep quality and sleep disorders (prevalence of obstructive sleep apnea and sleepiness) among occupational drivers in Iran and to determine which demographic factors and occupational habits are linked to road traffic accidents. MATERIAL AND METHODS In this analytic cross-sectional study 556 occupational road drivers from Shahroud city (in the...

Descriptive analyses of the magnitude and situation of road safety in general and road accidents in particular is important, but understanding of data quality, factors related with dangerous situations and different interesting patterns in a data is of even greater importance. Under the umbrella of an information architecture research for road safety in developing countries, the objective of th...

in this article, a new method for fusion of high resolution optical and radar data for higher quality road extraction is presented. the proposed methodology consists of two stages of separate road detection from each data and knowledge based fusion of results. neural networks are separately applied on high resolution ikonos and terrasar-x images for road detection, using a variety of texture pa...

The National Road Safety Strategy 2011-2020 outlines plans to reduce the burden of road trauma via improvements and interventions relating to safe roads, safe speeds, safe vehicles, and safe people. It also highlights that a key aspect in achieving these goals is the availability of comprehensive data on the issue. The use of data is essential so that more in-depth epidemiologic studies of risk...

The growing use of clusters in diverse applications, many of which have real-time constraints, requires Quality-of-Service (QoS) support from the underlying cluster interconnect. In this paper, we present an analytical model for a wormhole-switched router with QoS provisioning. In particular, the model captures message blocking due to wormhole switching and bandwidth sharing due to a rate-based...

When multiple ows including continuous media streams are simultaneously sent from a computer, allocation and management of both processor capacity and network bandwidth need to be considered. We propose a framework of Quality of Service (QoS) management inside a sending host that controls execution of sending threads in consideration of utilization of processor capacity and network bandwidth. T...

A s demand for child care in the United States has grown, so have calls for improving its quality. One approach that has been gaining momentum involves developing and implementing quality rating and improvement systems (QRISs): multi-component assessments designed to make child-care quality transparent to child-care providers, parents, and policymakers. QRISs provide simple, independent public ...

hen spring finally comes to New England, it brings with it gaping holes in roads. The larger of these potholes are patched, but the road can never be made smooth again. Smaller potholes, although a daily nuisance, are often not repaired at all. Something similar is happening in the area of information systems: People who need information to accomplish their tasks are finally being provided with...
