This paper describes an experimental augmented reality based system for overlaying computer generated information on the real world. Museum artefacts are digitised; 3D models are then created and rendered in an augmented reality environment providing the opportunity for museum visitors to visualise virtual artefacts in the context of real artefacts and other contextual information. Viewing 3D m...

EEG is a record of brain activity from various sites of the brain. Artefacts are unwanted noise signals in an EEG record. Classification of artefacts based on source of its generation like physiological artefacts and external artefacts. Body of the subjects are main source of Physiological artifacts, while external artefacts are from outside the body due to the environment or measuring devices....

I develop in this paper a conception of artefacts based on L. Wittgenstein's idea of family resemblance. My approach peruses the notion of frame, which was invented in cognitive psychology as an operationisable extension of this philosophical idea. Following the metaphor of life-cycle I show how this schematic notion of frame may be filled with the content relevant for artefacts if we consider ...

Paper-based artefacts (e.g., forms, manuals, questionnaires) are used ubiquitously and pervasively to support a wide set of activities. Education and Health Care are major examples of such endeavour. However, given the passiveness of the medium itself, several problems (e.g., communication, adjustment, lack of interactivity) are usually encountered within these activities which hinder human eff...

Elongation is a commonly found feature in artefacts made and used by humans and other animals and can be analysed in comparative study. Whether made for use in hand or beak, the artefacts have some common properties of length, breadth, thickness and balance point, and elongation can be studied as a factor relating to construction or use of a long axis. In human artefacts, elongation can be trac...

Nuclear mitochondrial DNA (mtDNA) segments (NUMTs) were discovered shortly after sequencing the first human genome. They have earlier been considered to represent archaic elements of ancient insertion events, but modern technologies and growing databases mtDNA NUMT sequences confirm that they are abundant some them phylogenetically young. Here, we build upon mtDNA/NUMT review articles published...

Ultrasound is used increasingly for diagnosing large vessel vasculitis (LVV). The application of Doppler in LVV is very different from in arthritic conditions. This paper aims to explain the most important Doppler parameters, including spectral Doppler, and how the settings differ from those used in arthritic conditions and provide recommendations for optimal adjustments. This is addressed thro...

This article is an attempt to initially characterize the oldest phase of LBK in Lublin region, or more precisely – within its eastern part, where all related discoveries are concentrated. The main point reference inventory discovered 2011-2012 Świerszczów (Hrubieszów Basin), which currently largest homogenous collection originating from this early LBK. artefacts described herein, as well stylis...

The accuracy of calculations of both the degree and angle of polarization depend strongly on the noise in the measurements used. The noise in the measurements recorded by both camera based systems and spectrometers can lead to significant artefacts and incorrect conclusions about high degrees of polarization when in fact none exist. Three approaches are taken in this work: Firstly, the absolute...
