Assessment of feedback modalities for wearable visual aids in blind mobility
PLoS ONE, 2017 Sensory substitution devices engage sensory modalities other than vision to communicate information typically obtained through the sense of sight. In this paper, we examine the ability of subjects who are blind to follow simple verbal and vibrotactile ...

Ultrahigh electron mobility in suspended graphene [PDF]
, 2008 We have achieved mobilities in excess of 200,000 cm2 V −1 s−1 at electron densities of ∼2 ×1011 cm−2 by suspending single layer graphene. Suspension ∼150 nm above a Si/SiO2 gate electrode and electrical contacts to the graphene was achieved by a ...

Mobile crowdsensing with mobile agents [PDF]
Autonomous Agents and Multi-Agent Systems, 2015 We introduce mobile agents for mobile crowdsensing. Crowdsensing campaigns are designed through different roles that are implemented as mobile agents. The role-based tasks of mobile agents include collecting data, analyzing data and sharing data in the campaign.

Understanding Immobility: Moving Beyond the Mobility Bias in Migration Studies
International Migration Review, 2020 This article suggests that there is a mobility bias in migration research: by focusing on the “drivers” of migration — the forces that lead to the initiation and perpetuation of migration flows — migration theories neglect the countervailing structural ...
