Vehicle routing with stochastic time-dependent travel times
TLDR
The variability in traffic flows is introduced into the model and the risk taking behavior of the planner can be taken into account during optimization, and a powerful objective function is proposed that captures the trade-off between the average travel time and its variance.
A high-resolution sensor based on tri-aural perception
TLDR
A high-resolution sensor composed of three ultrasonic sensors, one transmitter/receiver and two extra receivers, which allows a significant improvement in the information-extraction process and is impervious to measurement variations common to all three receivers.
Vehicle routing with dynamic travel times: A queueing approach
TLDR
The approach developed introduces mainly the traffic congestion component based on queueing theory, an innovative modeling scheme to capture travel times for vehicle routing problems with dynamic travel times due to potential traffic congestion.
One tone, two ears, three dimensions: a robotic investigation of pinnae movements used by rhinolophid and hipposiderid bats.
TLDR
Pinna mobility provides an echolocator with a mechanism for creating dramatic temporal cues for directional sensing which, unlike interaural timing differences, do not degrade with head size.
What Noseleaves Do for FM Bats Depends on Their Degree of Sensorial Specialization
TLDR
It is found that the noseleaf of M. microtis focuses the radiated energy better and yields better control over the emission beam, a capability that can be linked to the different ecological niches occupied by the two species.
A Queueing Framework for Routing Problems with Time-dependent Travel Times
TLDR
The approach developed introduces the traffic congestion component based on queueing theory to capture the stochastic behavior of travel times and generates an analytical expression for the expected travel times as well as for the variance of the travel times.
Evolving Batlike Pinnae for Target Localisation by an Echolocator
TLDR
A genetic algorithm (GA) is developped which in conjunction with an acoustic echo simulator allows to evolve desirable pinna shapes instead of having to design them.

TLDR
The main contribution of this paper lies in the analysis of which features of the proposed model are responsible for its high accuracy in estimating arrival times of overlapping echoes and how the characteristic measurement errors predicted by this analysis can be used to further investigate the accuracy of the SCAT receiver.
Broadband 3-D Sonar System Using a Sparse Array for Indoor Navigation
TLDR
This work constructs a low-cost, yet powerful, in-air sonar system, which is suited for a wide range of robotic applications, and describes an odometry application that estimates egomotion of a mobile robot using acoustic flow.
A realistic evaluation of indoor positioning systems based on Wi-Fi fingerprinting: The 2015 EvAAL-ETRI competition
TLDR
This is the first work in which Wi-Fi fingerprinting algorithm results delivered by several independent and competing teams are fairly compared under the same evaluation conditions, and indicates that the competing systems where complementary.
