  • Six-axis force sensors : a comparative study

    Creator:
    Valdes-Salazar, Juan C.
    Abstract:
    A comparative study of three six-axis force sensors selected after an extensive literature survey is presented. A sensor to measure ground contact force at each foot of a walking machine is recommended. Principles of force sensing are reviewed and characteristics of sensing elements are discussed. Results of simulation of three...

  • Activated carbon for improving diuron selectivity in beans

    Creator:
    Romero M., Carlos Eduardo
    Abstract:
    Activated carbon is effective in protecting beans from herbicide injury. In a field study, diuron [3-(3, 4- dichlorophenyl)- 1- 1- dimethyl urea], linuron [3- ( 3, 4- dichloropheny1)- 1- methoxy- 1- naethylurea], fluometuron [1, 1-dimethyl- 3-(α , α, α -trifluoro- m-toly1) urea], and metobromuron [3, (2- bromophenyI)- 1- 1- rnethoxy-...

  • A Homotopy Strategy for Accelerated Sampling

    Creator:
    Jensen, Andrew D.
    Abstract:
    Markov Chain Monte Carlo methods may be used to determine normalizations and moments of distributions. However, these methods may perform poorly when starting from distributions that have little overlap with the target. We develop a homotopy based iterative process of incremental importance sampling to normalize distributions when observations can only...

  • Information Theoretical Analysis of Self-Similar Trees

    Creator:
    Chunikhina, Evgenia V.
    Abstract:
    Tree-like patterns are ubiquitous in nature. Botanical trees, river networks, and blood systems are the most well-known examples of complex hierarchical systems met in observations. Interestingly, many of such systems exhibit statistical self-similarity. There are two main types of self-similarity: Horton self-similarity and Tokunaga self-similarity. Although there is an increased...

  • On the Dynamic Likelihood Approach to Data Assimilation for Stochastic Hyperbolic Geophysical Processes

    Creator:
    Foster, Dallas A.
    Abstract:
    Many geophysical phenomena exhibit complicated dynamics that, due to a variety of factors, diverge quickly from physical models. The arrival of new observations allows researchers to combine the model estimate with measurements in a statistical process called data assimilation to produce a revised estimate of the phenomenon. This assimilation of...

  • The Ocean Circulation and Carbon Cycle during the Last Glacial Maximum

    Creator:
    Muglia, Juan
    Abstract:
    During the Last Glacial Maximum (LGM, ∼ 21 ky before present) the atmospheric CO2 concentration was about 100 ppm lower than its pre-industrial (PI)value. The missing carbon from the atmosphere must have been stored in thedeep ocean during this period, but the mechanisms driving such re-distribution ofthe carbon cycle are...

  • Wetlands - San Juan County Best Available Science Synthesis, Chapter 2

    Creator:
    Adamus, Paul R. and Fralich, Richard
    Abstract:
    This document partially addresses the Wetlands component of San Juan County’s Critical Areas Ordinance (CAO). Drawing from a foundation in best available science, it describes important functions performed by the County's wetlands, effects of various activities on those functions, and strategies for protecting wetland functions from impacting activities, with an...

    Creator:
    Adamus, Paul R. and Earth Design Consultants, Inc.
    Abstract:
    This document provides definitions and a general overview of streams and lakes of San Juan County (SJC) and then describes impacts to these water bodies and strategies for determining widths of buffers that protect their functions. It similarly provides definitions and a general overview of SJC upland (terrestrial) habitats, describes...

  • Biomarkers of oxidative stress and DNA damage in agricultural workers

    Creator:
    Muniz, Juan Fermin
    Abstract:
    Pesticides are among the most pervasive environmental contaminants and they are an important potential risk for human health. Agricultural workers are constantly exposed to pesticide spray, drift and residues in the soil and foliage. Many agricultural pesticides are readily absorbed by the body, through contact with the skin, the respiratory...
