The paper describes the architecture of Text Mining services for the Knowledge Practices Laboratory1 (KP-Lab). The Trialogical Learning and Activity Theory, as a new paradigm of e-Learning, stands behind the KP-Lab system. This approach requires active goal-oriented participation of learners, sharing of learning materials (knowledge artefacts), distributed and highly customizable learning envir...

Artefacts are noises introduced to an EEG signal by patient’s movements and sources of electric field outside the patient’s body. The artefacts impede a doctor’s expertise and an automatic analysis of the signal. The most common and characteristic kind of artefacts are blinking artefacts. This paper presents a neural based approach to finding artefacts in the signal. The inputs to the network a...

Parametric ultrasound images visualising a patient’s brain perfusion often suffer from stripe artefacts – a darker, radially oriented image region originating from inhomogeneities in the cranial bone or the dura mater. We present an algorithm for detecting these artifacts with regard to automatic evaluation of parametric images. The algorithm exploits that stripe artefacts by virtue of their or...

To cite: Artul S. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013201379 DESCRIPTION High-resolution tomographic images acquired with a digital X-ray detector are often degraded by the so-called ring artefacts. Ring artefacts are the concentric rings superimposed on tomographic images. Artefacts in general can seriously degrade the quality of multidetector CT ...

In collaborative museum learning contexts, it is problematic that groups of museum visitors are not able able to touch, handle, and pass museum artefacts around during collaborative discussions. This can be due to the fragility of the artefacts themselves or due to the people discussing them being in different locations. Interacting with virtual representations of artefacts is a solution to the...

Mixed reality (MR) is a cutting-edge technology at the forefront of many new applications in tourism and cultural heritage sector. This study aims to reshape museum experience by creating highly engaging immersive for visitors combing real-time visual, audio information computer-generated images with artefacts customer displays. research introduces theoretical framework that assesses potential ...

The region of image compression since it is applicable to various fields of image processing. The key goal of compression is to cut back the space for storage and decrease the transmission cost and maintain the visual quality of image. This paper presents fundamental approach for analysis and evaluating the image compression techniques. This paper describes the many techniques which can be used...

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 ...
