Traditionally cognition has been regarded in terms of internal symbolic representations and computational processes, while the environment largely has been reduced to inputs and outputs. More recent situated cognition approaches emphasise the role of environmental resources in cognition, and today it is well known that artefacts affect, not only the individual, but also social interactions. Des...

The cutaneous recording of gastric myoelectrical activity of the stomach known as electrogastrography (EGG) seems to be the promising tool for the non-invasive assessment of gastric motility. Unfortunately the EGG recording is usually severely contaminated both by motion artefacts and endogenous biological noise source. In order to use EGG signals as reliable diagnostic tool it is necessity to ...

The ultimate aim of virtual reality is to present the user with an illusion of reality within a virtual environment. Visual artefacts that appear in a virtual reality system’s computer generated graphics can easily destroy this artificial sense of reality. Therefore in order to maintain an illusion of reality, it is essential to eliminate or hide such visual artefacts from the user. This paper ...

BACKGROUND Artefacts in images related to patient movement decrease image quality, potentially necessitating re-scanning, which leads to an extra radiation dose for the patient. Thus, avoiding patient motion reduces patient exposure to radiation. The aim of this study was to analyse image motion artefacts (MAs) and how they are affected by patient anxiety during cone beam computed tomography (C...

Technology increasingly plays a role in the way that we prepare for, celebrate, and reflect upon major life events. Modern digital artefacts, such as Facebook messages and digital photos, now stand alongside traditional artefacts, such as guest books and heirloom jewellery, as cherished mementos of these occasions. Considering how these physical artefacts are crafted provides a useful lens for ...

Visualization of cell migration during chemotaxis using spectral domain optical coherence tomography (OCT) requires non-standard processing techniques. Stripe artefacts and camera noise floor present in OCT data prevent detailed computer-assisted reconstruction and quantification of cell locomotion. Furthermore, imaging artefacts lead to unreliable results in automated texture based cell analys...
