  • Predicting instrument detection efficiency when scanning small area radiation sources

    Creator:
    Hart, Kevin G.
    Abstract:
    Accurate quantification of radionuclides detected during a scanning survey relies on an appropriately determined scan efficiency calibration factor (SECF). Traditionally, instrument efficiency was determined from a fixed instrument to source geometry. However, as is often the case, the instrument is used in a scanning mode where the source to instrument...

  • Calculation of scanning efficiencies for portable instruments used to detect particulate contamination

    Creator:
    Moss, Stephen Craig
    Abstract:
    Efforts are continually being made in remediation surveys to reduce the time and manpower required to perform work while maintaining the ability to detect low levels of contamination. To this end, organizations are utilizing portable instrumentation in conjunction with global positioning systems (GPS). This combination of technologies allows a surveyor...

  • Passive source tracking from spatially correlated angle-of-arrival data

    Creator:
    Haisch, Hansjoerg
    Abstract:
    This thesis presents a simulation technique for the post-detection of a point-source trajectory in an isotropic, stationary random medium. The two-dimensional source location is estimated from spatially correlated angle-of-arrival data which are collected simultaneously at two sensor positions. We assume that the data are collected at discrete, constant time intervals...

  • Paving the way for terrestrial laser scanning assessment of road quality

    Creator:
    Chin, Abby
    Abstract:
    With the growing trend in use of 3D laser scanning technology for data collection, it is important to study the various potential applications of this revolutionary technology. One such application is the measurement of road roughness at both large and small scales. At larger extents, terrestrial laser scanning (TLS) is...

  • Integrating product design and manufacturing process : a framework and implementation

    Creator:
    Li, Yu-An
    Abstract:
    The importance of integrating design and manufacturing becomes apparent when the increase in the degree of difficulty of change is observed as the product development proceeds from concept to production in a serial engineering process. The greatest opportunity in design for manufacture occurs at the initial design stage before any...

  • Studying the application of learning and growth metrics in healthcare using analytic hierarchy process

    Creator:
    Emami, Samin
    Abstract:
    Performance measurement is a process that begins with a decision on what to measure followed by identifying proper metrics and data sources. While there is substantial literature devoted to measuring the performance of hospitals and clinics in terms of indicators such as health outcomes and finances, it is vital for...

  • Linking GIS and a surface irrigation model to evaluate regional effects of furrow irrigation strategies

    Creator:
    Faux, Russell N.
    Abstract:
    The shallow aquifer in Northeast Malheur County, Oregon is polluted with Nitrates at concentrations exceeding federal drinking water standards. Efforts to solve the groundwater problems in this area have focused on developing farm management practices that will increase groundwater quality while maintaining agricultural production. Furrow irrigation is the dominant practice...

  • Mapping-grade GPS accuracy in second growth Douglas-fir forest

    Creator:
    Frank, Jereme M.
    Abstract:
    The global positioning system (GPS) has come into widespread use for many forestry applications. However, there is still some uncertainty as to how receivers perform in dense forest, where trees interfere with the GPS signal and increase error. These two manuscripts examine GPS accuracy and overall effectiveness within second growth...

  • An evaluation of a water, sanitation, and hygiene (WASH) program for rural communities in northern Afghanistan

    Creator:
    Costello, Denise H.
    Abstract:
    The Water, Sanitation and Hygiene (WASH) sector of international development works to increase access to sustainable, safe water and improved sanitation. Currently, at least 780 million people live without clean drinking water and 2.5 billion without access to improved sanitation (UNICEF & World Health Organization, 2012). Lack of access to...
