A T-dual version of the Gimon-Polchinski orientifold can be described by a configuration of intersecting Dirichlet seven branes and orientifold seven planes in the classical limit. We study modification of this background due to quantum corrections. It is shown that non-perturbative effects split each orientifold plane into a pair of nearly parallel seven branes. Furthermore, a pair of intersec...

In this paper we discuss trends and perspectives of automated data collection for Geographic Information Systems (GIS). We focus on aerial imagery and employ road extraction for the examples. The paper is split into three parts: In the first we present major findings for the (fully) automatic extraction of buildings, roads, and other topographic objects in the form of a model and a strategy. In...

In this paper, we present a cyclically time-expanded network model for simultaneous optimization of traffic assignment and traffic signal parameters, in particular offsets, split times, and phase orders. Since travel times are of great importance for developing realistic solutions for traffic assignment and traffic signal coordination in urban road networks, we perform an extensive analysis of ...

In this paper, we present a review of the recent advances in hybrid vehicle powertrain architectural design. The paper begins with a discussion and categorization of the various types of hybrid vehicles. The current leading technology is the one-mode design of the Toyota Hybrid System and the intent of the state-of-the-art architectures is to improve upon the perceived weakness of the one-mode ...

What Is a Bifurcation? The word bifurcate is commonly used to denote a split, as in “up ahead, the road bifurcates into two parts.” The use of the term in this context implies that a driver traveling on this road can make a realtime choice of being able to take one or the other branch of the road when the bifurcation point is reached. In mathematics, and in its application to neuroscience, the ...

Traffic congestion is becoming a serious environmental threat that must be resolved quickly. Traditionally, travel information systems have been specific to a particular mode of transport. For instance, traffic information (road conditions broadcast) has been directed at drivers. Instead, travel information systems are now being developed which incorporate route guidance systems to divert drive...
