The design of efficient routing algorithms is an important issue in dense ad hoc wireless networks. Previous work has shown that benefits can be achieved through the creation of a set of data “highways” that carry packets across the network, from source(s) to sink(s). Current approaches to the design of these highways however require a–priori knowledge of the global network topology, with conse...

Tolls are a recurring but not continuous feature in major highway financing policy in Spain. User tolls were the model used to finance the first expansion of the highway network, in the 60’s and early 70’s. The second wave of the highway network expansion took place in the late 80’s and early 90’s. The public budget was the usual source of funds used to pay for the highways built in this period...

Der von Christian Funke verfassten Monographie Asthetik, Politik und schiitische Reprasentation im zeitgenossischen Iran liegt seine Dissertation zugrunde, die unter dem Titel »Das Epos Staub Dreck: Die Asthetik der ›Grunen Bewegung‹ Irans Tradition« 2019 DVRW ausgezeichnet wurde. Islam- Religionswissenschaftler hat es sich zur Aufgabe gemacht, aus einer interdisziplinaren Perspektive den Disku...

We consider a variation of Voronoi diagram, or time-based Voronoi diagram, for a set S of points in the presence of transportation lines or highways in the plane. A shortest time-distance path from a query point to any given point in S is a path that takes the least travelling time. The travelling speeds and hence travelling times of the subpaths along the highways and in the plane are differen...

The biphenyl-bridged. chiral zirconocene complex rac-2.2' -biphenyl-bis( 3.4-dimethylcyclopentadienyl I zirconium dichloride catalyzes the reaction of 1.6and 1,7 -dienes with excess dibutyl magnesium to bis( butyl-magnesio-methyl '-substituted cycloalkanederivatives. Analogous reactions occur with butyl magnesium chloride and with heteroatom-t.:Ontaining dienes. The preference of 1.6-dienes for...

This article quantifies the value of U.S. highways. We develop a multisector general equilibrium model with many locations in United States (i.e., counties) and countries. In model, producers choose shipping routes subject to domestic international trade costs, endogenous congestion, port efficiency at transshipment points. Applying we find that removing Interstate Highway System reduces real G...
