This paper addresses the question if artifacts may be attributed some kind of agency. I take an activity-theoretical and instructional perspective, and argue that artifacts are used to guide actions. In other words, I claim that artifacts have instructional impact. In the introductory part of the paper is given an account of how three kinds of artifacts physical artifacts, linguistic representa...

on the one hand, the vacant position of study about impact of achaemenid empire on eastern states is due to silence by classic authors in dealing with these lands; and on the other hand, it is reffered to shortage of archeological artifacts relating to achaemenids at the given region. in the present essay, by the aid of reminiscent works and economic and administrative evidences obtained from e...

Purpose: The aim of the study is to characterize the ultrasound and Doppler ultrasound artifact patterns of foreign bodies and to define the role of elastography in their detection. Material and method: Two in-vitro environments including a lamb leg and a lamb stomach coated with ultrasound gel, were prepared. Twenty-seven foreign bodies grouped as metallic, organic and inorganic were evaluated...

Abstract Neuronal signals generally represent activation of the neuronal networks and give insights into brain functionalities. They are considered as fingerprints actions their processing across different structures brain. These recordings generate a large volume data that susceptible to noise artifacts. Therefore, review these ensure high quality by automatically detecting removing artifacts ...

Software Product Line Engineering (SPLE) promotes the development and maintenance of artifacts that can be reused in families of related software-intensive systems. As product lines are not necessarily disjoint and the development of product line artifacts is a demanding task, utilization of “related” or “similar” product line artifacts for creating or improving the artifacts of a particular pr...

Artifacts can be defined as any structure in an ultrasound image that does not have a corresponding anatomic tissue structure. Artifacts are a common occurrence in an ultrasound display since they are often the result of the physical properties of ultrasound itself. Recognizing artifacts is essential to proper ultrasound interpretation, as not identifying an artifact as such may lead to unwarra...

Artifacts are a significant problem affecting the accurate display of information during surgery. They are also a source of false alarms. A secondary problem is the inadvertent recording of artifactual and inaccurate information in automated record keeping systems. Though most of the currently available patient monitors use techniques to minimize the effect of artifacts, their success is limite...

ECG signals have been proven a very versatile tool for detection of cardiovascular diseases. But during recording of these signals, the ECG data gets contaminated by various noise signals caused by power line interference, base line wander, electrode movement, muscle movement (EMG) etc. These noise signals are known as artifacts. These artifacts mislead the diagnosis of heart which is not desir...

To understand the state of IS research is, to a large extent, to understand (1) what are considered IT artifacts by IS scholars, and (2) how do IS scholars approach IT artifacts in their studies. This study addresses these two questions by providing a conceptual model of five types of core IT artifacts and a five-facet framework of IS scholars’ approaches to studying IT artifacts. Using a criti...

There has been some debate about the correspondence between typicality gradients and category membership. The present study investigates the relationship between these two measures in the domains of animals and artifacts. Forty-two adults judged the degree of typicality or category membership of 293 animals and artifacts. The subjects' tendency for animals, but not for artifacts, was to make mo...
