without any doubt, road safety (rs) needs a precise planning in road accident prevention. rs effects on different fields of the life. therefore, response to this need in order to promote the rs as well as to save more lives is the most asset in each country. in the recent years, statistics have been shown that the numbers of mortalities due to road crashes decreased. this shows the true motion ...

This paper studies the analysis of reductio ad absurdum by Ibn Sı̄nā (known to the Latin West as Avicenna), who was born in 980 in a village near the Bactrian town of Balkh on the Silk Road, and died in 1037 after a career spent moving around within the present boundaries of Iran. References to Ibn Sı̄nā’s writings are to his Arabic texts listed in the bibliography, and are given in the format pa...

To improve the efficiency of existing emergency response and facility management systems, many utility companies choose to implement the ArcFM GIS. Based on my experience designing and implementing an ArcFM GIS for the Potomac Electric Power Company (PEPCO), Washington D.C., this paper provides a road map through implementation of an enterprise-wide GIS using technologies built-on ArcInfo 8 pla...

Injury Severity describes the severity of the injury to the person involved in the crash. Understanding the factors that influence injury severity can be helpful in designing mechanisms to reduce accident fatalities. Several research studies have examined the relationship between injury severity and the possible factors that can be related to the severity of the injury. These include driver-rel...

—Context-aware mobile computing aims at designing applications that automatically adapt their behaviors to the available location information and the available nearby sensors and devices. This is done in order to fulfill tasks in a way that suits users' current context best. To achieve this, context representation and manipulation are important issues, so as to establish formal context models. ...

Effective highway maintenance depends on several activities, including the understanding of current and the prediction of future pavement conditions and deciding how to best allocate limited resources for maintenance operations. In this paper, a dynamic micro-level simulation model of highway deterioration and renewal processes is presented. This model is calibrated with data from eight road se...

I describe the challenges involved in designing and evaluating high assurance, verifiable voting systems. I describe the Pret a Voter scheme that provides voterverifiablity with minimal trust in officials, software etc. I also describe a number of threats against voting schemes and the extent to which they apply to the basic Pret a Voter scheme. Some enhancements to the scheme designed to count...

The latest generations of road vehicles have seen a tremendous development in onboard electronic systems, which control increasingly large parts of the vehicle's functional-ity. HW/SW codesign techniques seem very useful for designing the nodes of the onboard computer network, and it is tempting also to apply it to the level of the overall electronic architecture. This paper discusses the diffe...
