Road extraction from GPS trajectories

, 2013
Road extraction methods generally have been conducted on remote sensing images, orthophotos, and LiDAR data sets, acquired using specific and expensive measurement instruments. An alternative data source, GPS vehicle trajectories, have started to be used

Disorientation detection by mining GPS trajectories for cognitively-impaired elders

, 2015
International audienceThe aging population is a major concern of human society in the 21st century. Elders who suffer physical or cognitive impairments often have difficulties in navigational tasks and remembering landmarks. As such, disorientation (i.e.,

Coordinated analysis of age, sex, and education effects on change in MMSE scores [PDF]

, 2013
We describe and compare the expected performance trajectories of older adults on the Mini-Mental Status Examination (MMSE) across six independent studies from four countries in the context of a collaborative network of longitudinal studies of aging.

Beyond Compliance: The Role of Climate Policy Stringency and Financial Institutions in Cleantech Startup Entry

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how environmental regulations can drive technological change, drawing on the innovation systems perspective and the strong Porter hypothesis (SPH). The SPH suggests that well‐designed stringent regulations can foster innovation and enhance firm competitiveness, performance, and survival, yet prior research remains largely ...
