Overview of the 2019 open-source IR replicability challenge (OSIRRC 2019)
No full textThe Open-Source IR Replicability Challenge (OSIRRC 2019), organized as a workshop at SIGIR 2019, aims to improve the replicability of ad hoc retrieval experiments in information retrieval by gathering a community of researchers to jointly develop a common Docker specification and build Docker images that encapsulate a diversity of systems and retrieval models. We articulate the goals of this workshop and describe the "jig" that encodes the Docker specification. In total, 13 teams from around the world submitted 17 images, most of which were designed to produce retrieval runs for the TREC 2004 Robust Track test collection. This exercise demonstrates the feasibility of orchestrating large, community-based replication experiments with Docker technology. We envision OSIRRC becoming an ongoing community-wide effort to ensure experimental replicability and sustained progress on standard test collections.Web Information System

Adaptive antenna composed of six dipole elements for wireless LAN - Part 2 -
Get PDFIn this paper, the adaptive antenna composed of six printed dipole elements loaded with the chip capacitor at the feed point instead of the varactor diode is numerically and experimentally analyzed. The operating frequencies of wireless LAN are from 2.4 GHz to 2.4835 GHz. In the numerical analysis, the electromagnetic simulator "WIPL-D" based on the method of moment is used.2009 IEEE Antennas and Propagation Society International Symposium (APSURSI) : North Charleston, SC, USA, 2009.06.1-2009.06.
