Visitor mobility in the city and the effects of travel preparation
Michael Bauder,Tim Freytag +1 more
TL;DR: In this paper, the authors explore the mobility paths of same-day visitors in Freiburg, Germany and show that well-prepared and not well prepared visitors are two distinct types of tourists with specific mobility patterns.
Journal ArticleDOI
Connectivity management in mobile ad hoc networks using particle swarm optimization
TL;DR: In this paper, the authors proposed a dynamic mobile ad hoc network (MANET) management system to improve network connectivity by using controlled network nodes, called agents, which have predefined wireless communication capabilities similar to the other nodes in the MANET, however their movements and thus their locations are dynamically determined to optimize network connectivity.

Three-dimensional dynamic deflections and natural frequencies of a stiff footbridge based on measurements of collocated sensors
Fanis Moschas,Stathis C. Stiros +1 more
TL;DR: In this article, a redundant system of collocated geodetic sensors and an accelerometer were used to measure the displacements of a stiff, 40m-long footbridge excited by essentially vertical synchronized jumps.

High-Precision Vehicle Navigation in Urban Environments Using an MEM's IMU and Single-Frequency GPS Receiver
TL;DR: A real-time sliding-window estimator that tightly integrates differential GPS and an inertial measurement unit to achieve reliable high-precision navigation performance in GPS-challenged urban environments using low-cost single-frequency GPS receivers is presented.
Journal ArticleDOI
A Localization Algorithm Based on V2I Communications and AOA Estimation
TL;DR: A GPS-free localization technique that exploits vehicle-to-infrastructure communications is proposed that provides for a vehicle to opportunistically use the beacon packets received from a roadside unit in order to obtain estimates of their angle of arrival.
