  • Low loss film bulk acoustic resonator in liquid environments 

    Pottigari, Sai Sumanth (University of Missouri--Columbia, 2008)
    A film bulk acoustic resonator (FBAR) is an acoustic resonator mass sensor using the resonance of longitudinal or shears acoustic waves. There is a significant Q factor loss in liquid medium due to acoustic energy loss. ...
  • Test taking motivation and item performance 

    Huang, Min, 1979- (University of Missouri--Columbia, 2008)
    The effect of test taking motivation on item performance is tested. The study proposes that 1) the item performance difference between high and low motivation groups varies with item difficulty; and 2) aberrant response ...
  • Ex situ variable angle spectroscopic ellipsometry studies on chemical vapor deposited boron-doped diamond films: layered structure and modeling aspects 

    Dudipala, Ajay Prasad Reddy (University of Missouri--Columbia, 2008)
    Diamond possesses several outstanding physical properties (mechanical hardness, thermal conductivity, chemical inertness and high index of refraction) that may qualify it to become an engineering material. However, diamond ...
  • Ensemble methods in large vocabulary continuous speech recognition 

    Chen, Xin, 1983- (University of Missouri--Columbia, 2008)
    Combining a group of classifiers and therefore improving the overall classification performance is a young and promising direction in Large Vocabulary Continuous Speech Recognition (LVCSR). Previous works on acoustic ...
  • Shape reconstruction from volumetric images 

    Heckenberg, Gregory (University of Missouri--Columbia, 2008)
    This thesis presents the research algorithms and techniques applied to three volumetric image problems(1) high quality mesh reconstruction from distance field volumetric data, (2) distance field surface approximation from ...
  • Runtime and jitter of a laser triggered gas switch 

    Hutsel, Brian T. (University of Missouri--Columbia, 2008)
    The University of Missouri has studied parameters affecting the runtime and jitter of a laser triggered gas switch. Experiments tested a variety of switch parameters including percentage of self-break and charge voltage. ...
  • Full similarity-based page ranking 

    Xu, Jingqian (University of Missouri--Columbia, 2008)
    The World Wide Web creates many new challenges to information retrieval.The sheer mass and almost anarchic structure of the Web makes effective search difficult. Some good search engine alleviate the problem to some extent ...
  • Feasibility of the nintendo Ds for teaching problem-based learning in kindergarten through twelfth grade students 

    Lipinski, Michael (University of Missouri--Columbia, 2008)
    Problem-based learning (PBL) is an instructional approach that has been employed successfully since the 1960s and continues to gain mainstream acceptance in many areas of study. PBL is an instructional, and curricular, ...
  • Anti-fog coatings using the super-hydrophobic approach 

    Almeida, Riberet (University of Missouri--Columbia, 2008)
    Surfaces with water contact angles in excess of 150⁰ have been attracting a great deal of attention. The work done here was in the design and development of an anti-fog coating. The hydrophilic as well as the hydrophobic ...
  • Content extraction, analysis, and retrieval for plant visual traits studies 

    Hao, Dayang (University of Missouri--Columbia, 2008)
    In recent years, automatic content extraction, analysis and retrieval for plant visual trait studies play a more important role than ever before, because traditional manual processing suffers two major issues: excessive ...
  • Design and construction of helmholtz coil for biomagnetic studies on soybean 

    Gyawali, Shashi Raj (University of Missouri--Columbia, 2008)
    A Helmholtz coil with a large usable area of uniform field was designed, constructed and characterized, specifically for bioelectric studies. The design and analysis of the coil were carried out through experiments and the ...
  • Modeling the behavior of a homopolar motor 

    Belarde, Gianetta Maria (University of Missouri--Columbia, 2008)
    The design, construction, and operating characteristics of a homopolar motor are described in this thesis using both physical experimentation and simulation software. This type of motor converts electrical energy into ...
  • The study of single phase diode rectifiers with high power factor and low total harmonic distortion 

    Tella, Pranavi Chowdari (University of Missouri--Columbia, 2008)
    The mains current in an ac/dc converter contains periodic current pulses due to the action of rectifier and output filter capacitor. The high current peaks cause harmonic distortion of the supply current and low power ...
  • MSM photodiode as the switching element in a photoswitch-based class E microwave power amplifier 

    Smith, Brady Christopher (University of Missouri--Columbia, 2008)
    A photoswitch is designed for use as the switching element in a 2 GHz class E amplifier. The application of this amplifier is as the final-stage amplifier in the transmit-receive module of a phased-array radar system. The ...
