In many dynamic systems large vibration amplitudes occur if the operation frequency is near resonance frequency. Also during passage result. order to reduce amplitude of oscillation a suitable excitation can be applied. The force driven single degree freedom harmonic oscillator used analyse reaction system variable analysis starts with mathematical transformation signal in identify influence di...

Nonlinear optical properties of organic semiconductors (OSCs) have been extensively investigated in the perturbative regime, while strong light induced high-order processes solid-state OSCs are less studied. Here, below-threshold harmonic generation is examined, both experimentally and theoretically, two thin film OSCs, that is, tetraphenylporphyrin zinc tetraphenylporphyrin. Results show π–π* ...

In this article we present results from the simultaneous nonlinear (second harmonic generation and two-photon excitation fluorescence) imaging and voltage clamping of living cells. Specifically, we determine the sensitivity to transmembrane potential of second harmonic generation by ANEP-chromophore styryl dyes as a function of excitation wavelength and dye structure. We have measured second ha...

We developed two techniques to address 3D volume parameterization and deformation mapping problems that arise in medical imaging [1]. The first algorithm finds a harmonic map from a 3-manifold to a 3D solid sphere and the second is a novel sphere carving algorithm which calculates the simplicial decomposition of a complex 3D image volume while preserving its surface topology. In this paper, we ...

Non-contact atomic force microscopy (AFM ) was employed following emersion to examine Au nanoclusters deposited from aqueous mixtures of HF and 10−4 M 2 onto Si(111). As the HF concentration is increased, the growth rates both parallel and perpendicular to the substrate of the approximately oblate Au hemispheroids increase. AFM images were obtained for times at which previously reported in situ...

We describe a theoretical analysis of the nonlinear dynamics of third-harmonic generation →3 via Kerr 3 nonlinearities in a resonant cavity with resonances at both and 3 . Such a doubly resonant cavity greatly reduces the required power for efficient harmonic generation, by a factor of V /Q2, where V is the modal volume and Q is the lifetime, and can even exhibit 100% harmonic conversion effici...

Magnetic resonance electrical impedance tomography (MREIT) is a new medical imaging modality visualizing static conductivity images of electrically conducting subjects. Recently, MREIT has rapidly progressed in its theory, algorithm, and experiment technique and now reached to the stage of in vivo animal experiments. In this paper, we present a software, named CoReHA 2.0 standing for the second...

An experimental study of the response to an impulsive driver in a low beta helium plasma is presented. Field line resonance ~FLR! spectra are recorded and compared to an ideal magnetohydrodynamic ~MHD! theory with finite ion cyclotron frequency corrections. The agreement between observed and predicted values is generally within the frequency resolution of the measurements except for the lowest ...

In this paper a well-known adjoint SISO Repetitive Control algorithm is extended to the multivariable case and its convergence properties are analysed. The new adjoint algorithm is validated using a simulation of an experimental facility consisting of a passive Naval vibration isolation mount that is combined with six active control channels located in a Stewart platform style arrangement. The ...
