Noninvasive determination of blood oxygenation in the brain by near-infrared reflectance spectroscopy
(1995)Continuous monitoring of blood oxygenation in brain is of great clinical interest. Hyperoxia and hypoxia, even over a short period of time, can lead to irreversible neurological damage. The recent progress in techniques ... -
Noninvasive tissue assessment
(2008-10-14)Methods and apparatus for non-invasively assessing physiological hard of soft tissue of human and other species are described. In a preferred embodiment, tissue is vibrationally stimulated in vivo through a frequency ... -
Nonjudging facet of mindfulness predicts enhanced smoking cessation in Hispanics
(2015)Although most smokers express interest in quitting, actual quit rates are low. Identifying strategies to enhance smoking cessation is critical, particularly among underserved populations, including Hispanics, for whom many ... -
Nonlinear Aeroelastic Analysis of UAVs: Deterministic and Stochastic Approaches
(2012-09-05)Aeroelastic aspects of unmanned aerial vehicles (UAVs) is analyzed by treatment of a typical section containing geometrical nonlinearities. Equations of motion are derived and numerical integration of these equations subject ... -
Nonlinear Dynamic Theory for Photorefractive Phase Hologram Formation
(1976-01-20)A nonlinar dynamic theory is developed for the formation of photorefractive volume phase holograms. A feedback mechanism existing between the photo-generated field and free electron density, treated explicitly yields the ... -
Nonlinear effects near an explosions
(1969)The purpose of this study is to find the dimensions of the shattered zone produced by the explosion of a spherical charge, in terms of the properties of the medium and the weight of the explosive charge; and then, to ... -
Nonlinear elastic buckling and postbuckling analysis of cylindrical panels
(2015)This paper revisits the buckling analysis of a benchmark cylindrical panel undergoing snap-through when subjected to transverse loads. We show that previous studies either overestimated the buckling load and identified a ... -
Nonlinear Fault Detection for Hydraulic Systems
(2003-01-01)One of the most important areas in the robotics industry is the development of robots capable of working in hazardous environments. As humans cannot safely or cheaply work in these environments, providing a high level ... -
Nonlinear Fault Detection for Hydraulics: Recent Advances in Fault Diagnosis and Fault Tolerance for Mechatronic Systems
(2002-10-01)One of the most important areas in the robotics industry is the development of robots capable of working in hazardous environments. As humans cannot safely or cheaply work in these environments, providing a high level ... -
Nonlinear geometric and material analysis of shell structures with particular emphasis on tubular joints
(1998)Linear and nonlinear analysis of shell structures are performed using finite elements. Shell elements are formulated to capture the linear and nonlinear behavior of shell structures. Although general, the elements are ... -
Nonlinear MDOF System Survival Probability Determination Subject to Evolutionary Stochastic Excitation
(2016)An approximate technique for assessing the reliability of nonlinear multi-degree-of-freedom (MDOF) systems subject to a non-stationary stochastic excitation vector is developed. The proposed technique can be construed as ... -
Nonlinear model of external respiration
(1995)A mathematical model of the external respiratory system is presented which integrates component models of airway mechanics and gas exchange at the pulmonary capillaries. The respiratory system is lumped into: (1) a conducting ... -
Nonlinear model reduction via discrete empirical interpolation
(2012)This thesis proposes a model reduction technique for nonlinear dynamical systems based upon combining Proper Orthogonal Decomposition (POD) and a new method, called the Discrete Empirical Interpolation Method (DEIM). The ... -
Nonlinear multicriteria optimization and robust optimality
(1997)This dissertation attempts to address two important problems in systems engineering, namely, multicriteria optimization and robustness optimization. In fields ranging from engineering to the social sciences designers are ... -
Nonlinear Nanophotonic Systems for Harmonic Generation, Parametric Amplification, Optical Processing and Single-Molecule Detection
(2015-02-19)Metallic nanoparticles support collective oscillations of conduction-band electrons, in response to light incidences. Such phenomenon is called localized surface plasmons, which confine large electromagnetic fields in ... -
Nonlinear neural codes
(2015-12-03)Most natural task-relevant variables are encoded in the early sensory cortex in a form that can only be decoded nonlinearly. Yet despite being a core function of the brain, nonlinear population codes are rarely studied and ... -
Nonlinear Optical Properties of Highly Aligned Carbon Nanotubes
(2012)Through polarization-dependent third hamonic generation experiments done on highly aligned carbon nanotubes on sapphire, the nonzero tensor elements of χ (3) have been extracted. The contribution of the weaker tensor ... -
Nonlinear oscillations in quantized linear discrete-time systems
(1971)This research presents the analysis of limit cycles occurring in the fixed-point implementations of digital filters due to multiplication rounding. The implemented digital filters are referred to as quantized linear ...
