This article presents the participation of the Center of Informatics and Information Technology group CITI in medical ImageCLEF 2013. This is our first participation and we submitted runs on the modality classification task, the ad-hoc image retrieval task and case retrieval task. We are developing a system to integrate textual and visual retrieval into a framework for multimodal retrieval. Our...

The present study explored the rhetorical representation of authorial identity signaled by interactive/interactional metadiscourse strategies and integral/non-integral citation patterns in international and Iranian local research article discussion sections. The study also explored variation in metadiscourse and citation resources across three subdisciplines of Language Testing, English Languag...

We study, in this paper, curvature inheritance symmetry (CI), £ξR a bcd = 2αR bcd , where α is a scalar function, for string cloud and string fluid in the context of general relativity. Also, we have obtained some result when a proper CI (i.e., α 6= 0) is also a conformal Killing vector.

While current techniques for human-robot interaction modeling are typically limited to restrictive commandcontrol style, traditional dialog modeling approaches are not directly applicable to robotics due to the lack of real-world integration. We present an approach that combines insights from dialog modeling with softwareengineering demands that arise in robotics system research to provide a ge...

We provide precise high-level models for eight fundamental service interaction patterns, together with schemes for their composition into complex service-based business process interconnections and interaction ows, supporting software-engineered business process management in multi-party collaborative environments. The mathematical nature of our models provides a basis for a rigorous execution-...
