Abstract
According to Mickens [R.E. Mickens, Comments on a Generalized Galerkin's method for non-linear **oscillators**, J. Sound Vib. 118 (1987) 563], the general HB (harmonic balance) method is an approximation to the convergent Fourier series representation of the periodic solution of a nonlinear **oscillator** and not an approximation to an expansion in terms of a small parameter. Consequently, for a nonlinear undamped Duffing equation with a driving force B cos ( ω x ) , to find a periodic solutio...

Examples of simulations in the associated articles can be reproduced by adjusting the model parameters in Main.m. An example parameter set resulting in **frequency** lock-in is included....A MATLAB implementation of our model for the simulation of dynamic ice-structure interaction is presented. The model allows for the simulation of the interaction between sea ice and vertically sided offshore structures and to reproduce and predict the development of ice-induced vibrations. This includes the regimes of intermittent crushing, **frequency** lock-in, and continuous brittle crushing.
The code shared here is excludes pre- and post-processing tools, ice buckling, and ice drift modules developed at TU Delft. The structure is represented by a single-degree-of-freedom **oscillator**.
The aim of sharing this code is to facilitate the further development of the model and its use in the design of offshore structures. For any questions related to its application, please contact dr.ir. H. (Hayo) Hendrikse (h.hendrikse@tudelft.nl). ...

Abstract
A method is described for constructing numerical high and low **frequency** filters for the filtration of the trajectories of strongly non-stationary stochastic processes (e.g. with a trend of the type of resonance functions). Measures of function **oscillations** and function variability are introduced, and by making use of them the problem of constructing the above-mentioned filters is formulated in terms of the calculus of variations. A compact algorithm for the numerical implementation of the met...

The aim of the project is to create an optical interferometer which can detect the acoustic analogue of a supernova explosion. The fingerprint of an acoustic wave propagating from a diapason will be measured. A Michelson Morley interferometer1 will be used, whereby analysis of the interference pattern will allow for the calculation of the **frequency** of the diapason....**frequency** 800Hz.txt...In a Michelson interferometer, light from a monochromatic source (S) is divided by a beam splitter (BS), oriented at an angle of 45° to the beam, producing two beams of equal intensity. The transmitted beam (T) travels to mirror M2 where it is reflected back to BS. 50% of the returning beam is then deflected by 90° at the beam splitter and is made to strike the detector (D). The reflected beam travels to mirror M1, where it is reflected. Again, 50% of the beam passes straight through the BS and reaches the detector.
The Laser is a He-Ne laser, having a polarized wavelength of 633nm (red). The wave is coherent and monochromatic; since the beam is coherent, light from other sources will not interfere with the interference pattern.
Mirrors provide a way for the beam to change its direction of travel, if M1 and M2 are misaligned, the recombination of the beams occurs at a different location in the BS, resulting in the formation of two signals on D which do not form an interference pattern.
When working with laser light, a cube beamsplitter (CB) possesses the best combination of optical performance and power handling ,CBs avoid displacing the beam by being perpendicular to the incident beam. To achieve the best possible performance, CBs should be operated with collimated light as convergent or divergent beams will contribute unwanted spherical aberrations to the setup.
A piezoelectric was connected to a signal generator and attached to M2. This acted as a test for the apparatus and allowed the mirror to **oscillate** at various **frequencies**. The distance travelled by M2 due to excitation of the piezoelectric was a secondary investigation inherent in the project.
The detector used allowed the intensity of light hitting it to be recorded. When two or more waves interact with one another an interference pattern is produced. This pattern is a result of the phase difference between the waves. When the waves are in phase constructive interference occurs and the resulting amplitude of the two superimposed waves is a maximum, on a screen, this is seen as a light fringe. When the waves are π out of phase, destructive interference occurs and the resulting amplitude is 0, on a screen this is seen as a dark fringe.

The data were originally collected for the paper "Olfactory Response as a Marker for Alzheimer’s Disease: Evidence from Perception and Frontal **Oscillation** Coherence Deficit" in Ziaeian Hospital, Tehran, Iran. The study was conducted on mild AD and normal participants.
This data includes EEG from 4 channels (Fp1-Fz-Cz-Pz) with A1 earlobe as reference. The sampling **frequency** is 200 Hz. It contains EEG segments during olfaction of two odors (Lemon and Rosewater). Each segment contains 1 second before and 2 seconds after the stimulus onset. Segments corresponding to Lemon odor are indicated by 0 and Rosewater segments are denoted by 1 in a vector inside the dataset. In addition, noisy epoch numbers are included in the dataset. The order of the channels in the dataset is as follows: Fp1 - Fz - Cz - Pz.
The data is preprocessed and eye-blink artifact was removed using FastICA algorithm.
Data on Iran-SIT score as well as participants' MMSE scores can be found in .xlsx file.
