Classical notations for service collaborations focus either on the control flow of participating services (interacting models) or the order in which messages are exchanged (interaction models). None of these approaches emphasizes the evolution of data involved in the collaboration. In contrast, artifact-centric models pursue the converse strategy and begin with a specification of data objects. ...

Today, software developers utilize different general-purpose (GPL) and domain-specific languages (DSL) to implement multi-language software applications (MLSA). MLSAs, thus, contain artifacts of different GPLs and DSLs, e.g., sourcecode files and configurations. In a recent study we found that refactoring an artifact can break artifact interaction and that interaction cannot be re-established b...

Estimates of the cardiac field artifact were obtained for each EEG/EOG channel of all-night sleep EEG/ECG recordings by heartbeat-related averaging of the EEG. These estimates – so-called templates – can be used for minimization of the artifact, e. g. by heartbeat-synchronized subtraction of the template. The 3-dimensional nature of the cardiac field artifact is demonstrated by constructing vec...

OBJECTIVE The aim of this study was to compare the degree of artifact reduction in magnetic resonance imaging achieved with slice encoding for metal artifact correction (SEMAC) in combination with view angle tilting (VAT) and multiacquisition variable resonance image combination (MAVRIC) for standard contrast weightings and different metallic materials. METHODS Four identically shaped rods ma...

Diffusion-weighted imaging (DWI) obtained with interleaved echo-planar imaging (EPI) pulse sequence has great potential of characterizing brain tissue properties at high spatial-resolution. However, interleaved EPI based DWI data may be corrupted by various types of aliasing artifacts. First, inconsistencies in k-space data obtained with opposite readout gradient polarities result in Nyquist ar...

image processing applications. In case of image compression, quality of decompressed image is also the criterion for evaluation of given coding scheme. In the process of compression –decompression various artifacts such as blocking artifacts, blur artifact, ringing or edge artifact are observed. However quantification of these artifacts is a difficult task. We propose here novel method to quant...

Artifacts have been proposed as basic building blocks for complex processes that are driven by life-cycle aware data objects. An artifact choreography describes the interplay of several artifacts from which the process “emerges”. By design, an artifact choreography is tightly coupled to the process’ underlying data model which gives rise to complex interactions between artifacts. This paper pre...

Pseudo-Pseudo-Myocardial Infarction To the Editor: Hung and colleagues1 present a very important example of a pseudo-infarction pattern presumably related to pancreatitis, one of several clinical situations in which thrombolytic therapy is either not indicated or contraindicated. I am intrigued by the pattern of the bizarre T waves in the limb leads and wonder if part or all of this phenomenon ...

this research study investigated the development of listening proficiency level by the aid of different media- tional artifacts in systemic theoretical instruction (sti). the study considered whether exposing learners to different types and various numbers of mediating artefacts would increase their awareness towards listen- ing concepts after two months, and consequently promote their listenin...

the purpose of the present research was to investigate the relationships between justice perceptions, employee's misbehavior and cynicism to organization because very few studies have looked at the role of justice and cynicism in the prediction of employee's misbehavior in public organizations. according to the purpose of study, the present research is developmental research. also acc...
