The performance of human-robot collaboration tasks can be improved by incorporating predictions of the human collaborator's movement intentions. These predictions allow a collaborative robot to both provide appropriate assistance and plan its own motion so it does not interfere with the human. In the …

The Compassberg Protected Environment (CPE) in South-Africa suffers severely from erosion in the form of gullies. Herbivory, bare soil, little water capture and lack of vegetation are the most important factors that contribute to erosion in the CPE. Grazing lawns are a vegetation type that is only found …

Abstract: Plan adaptation during the course of (chemo)radiotherapy of H&N cancer requires repeat CT scanning to capture anatomy changes such as parotid gland shrinkage. Hydration, applied to prevent nephrotoxicity from cisplatin, could temporarily alter the hydrogen balance and hence the captured anatomy. …

We present a novel hierarchical model for human activity recognition. In contrast with approaches that successively recognize actions and activities, our approach jointly models actions and activities in a unified framework, and their labels are simultaneously predicted. The model is embedded with a …

Using mobile technology to capture behavioural patterns and affective responses within activity-based work environments

Coupling beams between shear walls are one of the key elements for energy dissipation in tall buildings. A representative mathematical model of coupling beam should represent flexure, shear and interface slip/extension mechanisms simultaneously. This goal can be achieved by using either detailed finite …

Introduction: Falling causes long term disability and can even lead to death. Most falls occur during gait. Therefore improving gait stability might be beneficial for people at risk of falling. Recently arm swing has been shown to influence gait stability. However at present it remains unknown which …

Researchers in CSCL have used a wide range of qualitative and quantitative methods to track students' cognitive involvement during collaboration. However, neither individual method suffices the need to capture the dynamic evolvement of students' epistemic engagement in CSCL. We developed Epistemic Synchronization …

Purpose - Peer instruction has been widely adopted as an instructional method in higher education. However, due to students' different preconceptions, the authors argued that peer instruction is not a panacea in international business education when students' prior knowledge extensively varies. The paper …

Exergames provide a challenging opportunity for home-based training and evaluation of postural control in the elderly population, but affordable sensor technology and algorithms for assessment of whole body movement patterns in the home environment are yet to be developed. The aim of the present study …
