This data shows the simulation results of backstepping control applied to a pair of synaptically coupled Fitzhugh-Nagumo neurons. Many different scenarios are examined for three different purposes. The purposes are to obtain a controller to track a constant and periodic references and also a specific controller which initiate **oscillations** without the need of an external reference signal. The scenarions involve different controller gains, different reference levels, different **frequencies** and other certain parameters. This data is submitted to accompany a paper to be submitted to Elsevier Communications in Nonlinear Science and Numerical Simulations. ...This data shows the simulation results of backstepping control applied to a pair of synaptically coupled Fitzhugh-Nagumo neurons.

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). ...

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.

... Operating measurements from three multi-week test campaigns of the natural circulation FLiBe loop. This system is investigating thermal hydraulic behavior of the molten salt BeF_2 -LiF (33 - 67 mol %). The system behaves in a stable fashion, but shows unusual local transients, such as flow break-down in the riser and thermal jumps at the cooler exit. Heat transfer shows promising trends that FLiBe will behave as a normal heat transfer fluid, as long as salt purity can be maintained. The most recent test shows heat transfer degradation that is likely a result of oxides and impurities. The data archive contains as-built dimensions, Matlab analysis codes, and the raw data files.

... In the present work a model for the correlation between magnetocrystalline anisotropy energy and Barkhausen noise is proposed. The link between the magnetocrystalline anisotropy energy and the magnetic Barkhausen noise is due to the influence of the crystallographic texture on the domain nucleation process which produces the Barkhausen signal in the branch from saturation to remanence. The statistical distributions of magnetic free poles and local fields of nucleation and subsequent growth of reversed domains were obtained for a large number of grain boundaries and used to estimate the number and size of Barkhausen events at each angular position from 0 to 360° in ten degree-steps. The good agreement observed between the modeled magnetocrystalline energy and the prediction of this energy made from X-ray texture and Barkhausen noise measurements corroborates the validity of the proposed model.

... In the article we calculated and discussed the energy cost for performing software updates in LPWAN networks LoRa, SigFox and IEEE-802.15.4g. The energy cost is determined for three different scenario's: 1) a full system update; b) an application update; c) a MAC update. In each scenario, different update methods are considered. The excel file contains the raw input data (first sheet) gathered from datasheets, standard specifications, as well as the transaction sizes in different scenario's using different update method. The transaction sizes were determined by examining the sizes of the object files and firmware in the different update scenario's and for the different update methods. The three other sheets contain the processed data presented and discussed in the article. The excel also contains VB macro's to calculate the energy consumption in the downlink for a particular transaction size (i.e. software update in our case) and technology. They are used in the last three sheets in the excel workbook.
