    • Zebrafish Video Analysis System for High-Throughput Drug Assay

      Rodríguez, Jeffrey J.; Todd, Douglas Wallace; Rodríguez, Jeffrey J.; Powers, Linda S.; Tharp, Hal S. (The University of Arizona., 2016)
      Zebrafish swimming behavior is used in a new, automated drug assay system as a biomarker to measure drug efficiency to prevent or restore hearing loss. This system records video of zebrafish larvae under infrared lighting using Raspberry Pi cameras and measures fish swimming behavior. This automated system significantly reduces the operator time required to process experiments in parallel. Multiple tanks, each consisting of sixteen experiments are operated in parallel. Once a set of experiments starts, all data transfer and processing operations are automatic. A web interface allows the operator to configure, monitor and control the experiments and review reports. Ethernet connects the various hardware components, allowing loose coupling of the distributed software used to schedule and run the experiments. The operator can configure the data processing to be done on the local computer or offloaded to a high-performance computer cluster to achieve even higher throughput. Computationally efficient image processing algorithms provided automated zebrafish detection and motion analysis. Quantitative assessment of error in the position and orientation of the detected fish uses manual data analysis by human observers as the reference. The system error in orientation and position is comparable to human inter-operator error.
    • ZERO-ONE PROGRAMMING ANALYSIS OF MINE PRODUCTION SCHEDULING PROBLEMS.

    • Zhoukoudian: A synthesis of research to date

      Olsen, John W.; Della Croce, Anthony (The University of Arizona., 1995)
      The site of Zhoukoudian has been studied for over 70 years. During this time, a great deal of change has occurred in both analytical methodology and paradigmatic models concerning human prehistory. Zhoukoudian presents an opportunity to study both issues of early hominid behavior and the evolution of palaeoanthropological, geological, dating methodology and palaeoenvironmental research over the last eight decades. Zhoukoudian was the first site to exhibit verifiable evidence for the presence of early hominids in East Asia (more than 45 individuals). The site has been established as containing Middle and Upper Pleistocene components. The majority of these (e.g., Locality 1) fall within a Middle Pleistocene context, while the Upper Cave represents an Upper Pleistocene occupation of the site. Modem studies are suggested in light of the recent reworking of some fundamental concepts at Zhoukoudian. These include evidence for hunting vs. scavenging, fire usage and duration of occupation of the site by early hominids, all of which need reevaluation.
