Using a combination of statistical mechanics and finite-element interpolation, we develop a coarse-grained (CG) alternative to molecular dynamics (MD) for crystalline solids at constant temperature. The new approach is significantly more efficient than MD and generalizes earlier work on the quasicontinuum method. The method is validated by recovering(More)
This paper presents an approach to verifying the activities of daily living of older adults at their home. We verify activities, instead of inferring them, because our monitoring approach is driven by routines, initially sketched by users in their environment. Monitoring is supported by a lightweight sensor infrastructure, comprising non-intrusive,(More)
This study examines the process of learning to walk from a functional perspective. To move forward, one must generate and control propulsive forces. To achieve this, it is necessary to create and tune a distance between the centre of mass (CoM) and the centre of pressure (CoP) along the antero-posterior axis. We hypothesize that learning to walk consists of(More)
Aging creates needs for assistive technology to support all activities of daily living (meal preparation, dressing, social participation, stove monitoring, etc.). These needs are mostly addressed by a silo-based approach that requires a new assistive service (e.g., a reminder system, a pill prompter) to be acquired for every activity to be supported. In(More)
There is a growing interest for Assistive Technologies (AT) for aging in place. However, acceptance and adoption of AT in older adults remain problematic. This study investigates the perceived AT needs for three domains (everyday activities, safety and social participation) among 50 community-dwelling older adults and their caregivers. Our results indicate(More)
