It is widely accepted in the brain computer interface (BCI) research community that neurological phenomena are the only source of control in any BCI system. Artifacts are undesirable signals that can interfere with neurological phenomena. They may change the characteristics of neurological phenomena or even be mistakenly used as the source of control in BCI systems. Electrooculography (EOG) and...

conclusions the type of materials can influence the obtained gsv. different materials cause various amounts of artifacts due to differences in density and atomic number. results according to the mean gsv of the five different materials, the majority of artifacts produced were as follows: tempbond > zoe > mta > gi (chemfil dentsply) > gi (gc, fuji ιx). materials and methods samples of five cemen...

Model-driven development (MDD) for cyber-physical systems leverages sophisticated tool chains to translate models into programming language artifacts. As minuscule model changes can entail severe changes to generated artifacts and their integration with handcrafted artifacts, evolving models can produce unforeseen challenges. Reporting outdated handcrafted artifacts, generated artifacts with mi...

chipped stones, like many other archaeological artifacts, change in their original context. one of the most important changes is breakage. although it is clear that chipped stones which are gathered by archaeologists might have been broken, there have been few discussions made on the estimating the original number of chipped stones before breaking. in this article we have introduced different m...

PURPOSE To evaluate the differences in image quality of carotid computed tomographic angiography (CTA) of patients injected with contrast material in their right arms versus patients injected with contrast material in their left arms. MATERIALS AND METHODS Patients who had cerebrovascular accidents and subsequently underwent CTA were included in the study. Contrast material was injected into ...

During the systems engineering process many heterogeneous artifacts which belong to different engineering disciplines and describe different views upon the product to be developed are produced. In order to integrate these artifacts, to increase the level of reuse, or to evaluate and implement changes, we need semantically rich relations between development artifacts and the parts of the product...

The concept of product semantics and its focus on meaning is used to interpret design research as design. It is argued that we may conceive of design research as design in two realms: The practical and the academic. In doing design research, there is a reciprocal shaping of artifacts: Better artifacts (contributions to practice) through appropriation of knowledge and methods from the academic r...

Coordination Artifacts are first-class software entities that encapsulate an abstract communication pattern either among Agents or between an Agent and its environment. By separating Coordination Artifacts from Agents in a Multi-Agent System (MAS), both implementations are simplified: Coordination Artifacts become an ideal means for dealing with systemic issues, while the remaining Agent code c...
