International Conference on Applications of Modal Analysis '99: Recent Advances in Modal Analysis Practice
Wireless Sensor Network (WSN) is becoming a more and more popular research area since its emergence. Many WSN researches rely on practical experiments in real wireless networks. However, to setup and conduct such an experiment is always cumbersome and time-consuming. So in this thesis, we design and implement a WSN testbed to solve the problem and help user focus on their researches. Our testbed provides necessary modules and service, such as command dissemination and feedback module, data logging and collection module, network programming module and time synchronization service. Different from other existing testbeds, our testbed removes wire connections and gateways, which are used for transmitting commands, feedbacks and users’ programs, between nodes so that it provides high flexibility in deployment and reduces costs. This testbed...
This paper describes our participation in the INEX 2008 Link the Wiki track. We focused on the file-to-file task and submitted three runs, which were designed to compare the impact of different features on link generation. For outgoing links, we introduce the anchor likelihood ratio as an indicator for anchor detection, and explore two types of evidence for target identification, namely, the title field evidence and the topic article content evidence. We find that the anchor likelihood ratio is a useful indicator for anchor detection, and that in addition to the title field evidence, re-ranking with the topic article content evidence is effective for improving target identification. For incoming links, we use exact match and retrieval method with language modeling approach, and find that the exact match approach works best. On top of t...
The Bc mass and lifetime measurements using the exclusive decay Bc->Jpsi pi at the LHCb experiment were studied. About 310 signal events are expected for a data set which corresponds to an integrated luminosity of 1 fb-1, with a B/S ratio around 2. Based on these data, the Bc mass and lifetime can be measured with expected statistical errors below 2 MeV/c^2 and 30 fs, respectively.
