More and more solid-state magnetic field sensors such as Hall devices are used in eddy current inspection (EC) to acquire magnetic field signals. This work extends the previous analytical model, i.e. 2D Extended Truncated Region Eigenfunction Expansion (ETREE) of EC, and focuses on establishment of 3D ETREE of multi-frequency eddy current inspection (MFEC) on stratified conductors, while taking...

We investigate the photon efficiency of frequency-domain fluorescence lifetime imaging microscopy, using both theoretical and Monte Carlo methods. Our analysis differs from previous work in that it incorporates the data fitting process used in real experiments, allows for the arbitrary choice of excitation and gain waveforms, and calculates lifetimes as well as associated F-values from higher h...

Competing linear, quasi-linear and non-linear hydraulic mount formulations of fixed and free decoupler types are comparatively evaluated for transient responses. First, features of the realistic excitation conditions are addressed. For instance, the mean load itself may vary with time, and several sinusoidal or transient excitations may be simultaneously present. Second, a multi-staged top cham...

Time of flight mass spectrometry with multi-ion coincidence detection has been used to investigate ionic photofragmentation of formic acid following O 1s excitation and ionization. Multi-ion coincidence spectra (PEPICO and PEPIPICO), branching ratios (BR) and partial ion yields (PIY) are reported. The multi-ion coincidence detection is used to identify the dissociation channels following O 1s e...

In statistical parametric speech synthesis, creaky voice can cause disturbing artifacts. The reason is that standard pitch tracking algorithms tend to erroneously measure F0 in regions of creaky voice. This pattern is learned during training of hidden Markov-models (HMMs). In the synthesis phase, false voiced / unvoiced decision caused by creaky voice results in audible quality degradation. In ...

A novel analytical method for atmospheric polycyclic aromatic hydrocarbons (PAHs) was developed based on laser induced fluorescence (LIF) of samples on quartz multi-channel polydimethylsiloxane traps. A tunable dye laser with a frequency doubling crystal provided the excitation radiation, and a double monochromator with a photomultiplier tube detected emitted fluorescence. The method allowed fo...

Nano-structuring can significantly modify the properties of materials. We demonstrate that size-dependent modification of the spin-wave spectra in magnetic nano-particles can affect not only linear, but also nonlinear magnetic response. The discretization of the spectrum removes the frequency degeneracy between the main excitation mode of a nano-particle and the higher spin-wave modes, having t...

In this paper, a novel method is proposed for multi-information acquisition from the electromagnetic flow meter, using magnetic excitation to measure the fluid velocity and electrochemistry impedance spectroscopy (EIS) for both the fluid quality and the contamination level of the transducer. The impedance spectra of the transducer are measured with an additional electrical stimulus in series wi...

Neuro-inspired implementations have attracted strong interest as a power efficient and robust alternative to the digital model of computation with a broad range of applications. Especially, neuro-mimetic systems able to produce and process spike-encoding schemes can offer merits like high noise-resiliency and increased computational efficiency. Towards this direction, integrated photonics can b...
