In this paper, I provide an easy road to nominalism which does not rely on a Field-type nominalization strategy for mathematics (Field 1980). According to this proposal, applications of mathematics to science, and alleged mathematical explanations of physical phenomena, only emerge when suitable physical interpretations of the mathematical formalism are advanced. And since these interpretations...

Road traffic safety is receiving increasing attention. Different real-time safety indicators relying on traffic sensor data can be found in the literature. Some are based on the posterior analysis of crash and traffic data; while others are based on real time traffic risk assessment using microscopic parameters (e.g., short time headways). Other non-traffic related parameters have an impact on ...

To paraphrase Mark Twain, reports of either the recent death or coming dominance of anonymity have been greatly exaggerated. This paper is a beginning effort to lay out some of the conceptual landscape needed to better understand anonymity and identifiability in contemporary life. I suggest 7 types of identity knowledge involving legal name, location, symbols linked and not linked back to these...

This paper investigates the e ect of performance measurement on the optimal e ort allocation by salespeople when rms are concerned about retention of salespeople with higher abilities. It shows that introducing salespeople performance measurement may result in productivity, pro t, and welfare losses when all market participants optimally respond to the expected information provided by the measu...

This paper discusses the concept of a structurally safe traffic system. The crucial question is how potential errors occurring in traffic can be reduced by revising the layout of the road environment. Two considerations play an important role: inherent safety and self-explaining properties. Inherent safety refers to the reduction of potentially dangerous encounters. Traffic systems having self-...

This paper presents a method for hypothesis verification in automatic road extraction based on the topology of road networks. The method includes the generation of topology of road networks, verification of hypothesized road segments and prediction of missing road segments. The topology of road networks is generated using small scale aerial images as they exhibit a global structure of road netw...

Road centerline extraction from imagery constitutes a key element in numerous geospatial applications, which has been addressed through a variety of approaches. However, most of the existing methods are not capable of dealing with challenges such as different road shapes, complex scenes, and variable resolutions. This paper presents a novel method for road centerline extraction from imagery in ...
