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.

Transonic flow fields are considered where self-excited shock wave oscillation prevails. To control the shock oscillation, a passive technique in the form of an open rectangular cavity is introduced on the upper surface of the airfoil where the shock wave oscillates. Reynolds Averaged Navier-Stokes (RANS) equations have been used to predict the aerodynamic behavior of the baseline airfoil and airfoil with cavity at Mach number of 0.729 and at angle of attack of 5˚. The aerodynamic characteristics of the baseline airfoil are well validated with the available experimental data. It is observed that the introduction of a cavity around the airfoil upper surface can completely stop the self-excited shock wave oscillation and successively improve the aerodynamic characteristics.

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.

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).

... Compression is built into a broad range of technologies like storage systems, databases, operating systems and software applications. It refers to the process of reducing the quantity of data used to represent the content without excessively reducing the quality of the original data. Their main purpose is to reduce the number of bits required to store and/or transmit digital media in a cost effective manner. There are number of data compression techniques used and they can be categorized as Lossless and Lossy compression methods. In this paper, we made an attempted to discuss about some of the general concepts of compression algorithm using Lossless and Lossy methods of compression.

... The Unified Astronomy Thesaurus (UAT) is an open, interoperable and community-supported thesaurus that unifies the existing Astronomy & Astrophysics thesauri into a single, freely-available open thesaurus for astronomical objects and concepts. These files introduce the UAT and describe the unique combination of conditions that lead to its development, as well as the people, organizations and tools involved in its construction. Because astronomy and astrophysics are fast-moving fields (terms such as 'exoplanets' and 'dark energy' were relatively unknown 10 years ago), the poster will also describe the ways tha t the UAT will leverage expertise from astronomers, physicists and librarians to keep the thesaurus both current and accurate. One of the primary drivers behind the creation of the UAT is the wish to support semantic enrichment of astronomy literature and databases. We anticipate it will be used as a common language across publishers and platforms, to connect articles and data sets. We also hope this unified vocabulary will inspire a new range of cross-silo data sharing. The UAT began as a collaboration between the American Institute of Physics (AIP) and Institute of Physics (IOP), which dona ted their collection astronomy of terms to the AAS. SPIE has also donated their astronomy terms towards the effort. Our plans include providing a community-supported mechanism for reviewing, discussing, and evaluating the continuous evolution of terminology in astronomy and astrophysics.
