Characterization of charge collection in photodiodes under mechanical strain: comparison between organic bulk heterojunction and amorphous silicon
Abstract The photo- and dark currents of organic bulk heterojunction and amorphous silicon photodiodes are measured during bending to determine the effects of mechanical strain on electrical properties. Charge collection…

Activity-based advertising: techniques and challenges
In this paper we describe three types of activity-based advertising: 1) inferring general interest categories, 2) adapting advertising to the current context, and 3) using contextual histories to predict the…

Improving location fingerprinting through time-shifted interval labeling
By using an accelerometer to detect whether a device is moving or still, the system can learn from all radio measurements in a stable time interval whenever it was previously…

Assessing Auroral Electric Field Variance with Coherent and Incoherent Scatter Radar
Line-of-sight F region plasma drifts measured with the Poker Flat Incoherent Scatter Radar (PFISR) during the NASA JOULE II experiment period are compared with estimates derived from E region coherent scatter spectra observed with a 30 MHz imaging radar on common…
