Mode **frequency**...In this work we have presented an analogy between the coupled vibrations of two classical
**oscillators** and the **oscillations** that take place in a laser cavity. Our aim is to understand classically
the causes that lead to the phase diffusion in a system of coupled classical **oscillators** and to explore
possibilities of any relationship between phase fluctuation and the **frequency** difference. The
equations of motion for the classical **oscillators** have been derived and solved, for different values of
coupling coefficients, to obtain the expressions for the mode frequencies1. The solutions, while plotted
graphically have led us to the conclusion that in classical **oscillators** the mode **frequencies** of the
**oscillators** are far apart if their **oscillation** is heavily coupling dependent and consequently the phase
relationship of the **oscillators** fluctuate vigorously and frequently, which is the converse of what
happens in a laser cavity consisting atomic **oscillators**.

Free vibrating motion can take place in an acoustic media. This motion can be steady hence have constant periodic variations or unsteady and thus experience light damping or heavy damping. We give a modeled analysis of unsteady periodic motion of an **oscillator** in a cylindrical acoustic medium that allow such waves to be transmitted through them. This has been approached by calculating variation within the proposed boundary functions and boundary potentials. Limitations for these calculations have been done depending on the time, and how free **oscillations** are expected to behave in cylinder carrying a suspended mass. This work investigated motion by constructions that interact with their environment with the acoustic media. Since the dynamics considered here were very complex, modeling the system with one grade of free motion and applying different types of constructions whether ground, underground, cylindrical, spherical constructions and containers was considered. This work borrowed heavily on the modeling of seismic and blast waves as modeled with rigid inclusions containing elastically fastened mass interacting continuous solid medium. This study joined motion of any continuous medium with other discrete systems. The results displayed measurement systems for wave processes having interference at their eigen- **frequencies** just like those under seismic wave interactions and this work considered the result as similar to those in discrete systems....**Oscillations** ...

Summary
Raw and reorganised data of the electromechanical impedance of an Macro-Fiber Composite transducer bonded to a 6082 aluminium beam. The experiment was conducted over a range of damage levels (4) and temperatures (5, from 0°C to 40°C). A total of 320 measurements were carried out.
Data was acquired using the Analog Devices AD5933 impedance analyser. Measurements were carried out in an environmental test chamber at the Surrey Space Centre, UK.
Details
This dataset contains raw output as well as aggregated data with the measurement software provided with the Analog Devices AD5933 evaluation board. All data in the dataset is 'tidy' (each variable forms a column, each observation forms a row).
A total of 320 measurements are contained in this dataset - 4 damage levels and 5 temperature values, 16 iterations each.
Multi-point calibration was performed with a 1% tolerance 470 Ohm resistor. A 1% tolerance 470 Ohm resistor was also placed in the Rfb location on the AD5933 evaluation board. The **frequency** sweep start **frequency** was 35 kHz, with delta **frequency** of 64 Hz and 512 increments. The internal **oscillator** of 16.776 MHz was used. The output excitation range was 1 V p-p. DDS settling time cycles was set to X2 (double).
The experiment was conducted in an environmental test chamber, model WIR 12-30 produces by Design Environmental in 2002 for the Surrey Space Centre, UK. The chamber conforms to EN 50081-1 electromagnetic compatibility standards and has received periodic calibrations.
Further information available upon inquiry (and in a forthcoming publication).
Aggregated data
The aggregated data contains the following variables:
damdamage level - factor with 4 levels d0 ... d3
temptemperature in degrees Celsius
iterinteration number
freqfrequency
magmagnitude of complex impedance
argargument (phase) of complex impedance
realreal part of complex impedance (resistance)
imagimaginary part of complex impedance (reactance)
Raw data
Raw data in csv format contains the following variables:
**Frequency**
Impedancemagnitude of complex impedance
Phaseargument of complex impedance, in degrees
Realinternal real register value
Imaginaryinternal imaginary register value
Magnitudemagnitude of complex impedance before multiplying by the gain factor
The filenames contain three metadata fields, separated with a dash:
damage level (factor)
temperature (degrees Celsius)
iteration number
Example: file d3-30-15.csv represents data acquired with damage level d3, at temperature of 30 degrees Celsius, iteration no. 15. ... Summary
