Abstract: During this paper we target the combination of web accessible physics experiments (VPLabs) combined with the Sun's toolkit for making cooperative 3D virtual worlds. Among such a cooperative setting these tools give the chance for academics and students to figure along as avatars as they control actual instrumentation, visualize natural phenomenon generated by the experiment, and discuss the results. Especially we'll define the steps of integration, future goals, yet because the price of a collaboration area in Wonderland's virtual world.

Abstract: The chemical spray pyrolysis technique (SPT) has been, throughout last 3 decades, one amongst the most important techniques to deposit a large type of materials in thin film kind. The prime requisite for getting sensible quality thin film is that the optimization of propaedeutic conditions viz. substrate temperature, spray rate, concentration of solution etc. However, in recent years a stress has been given to a range of atomization techniques like supersonic nebulisation, improved spray reaction, corona spray transformation, electricity spray transformation and microchip primarily based spray transformation. This is often the foremost crucial parameter because it permits management over the scale of the droplets and their distribution over the preheated substrates. An intensive review of thin film materials ready throughout the last ten years is given to demonstrate the flexibility of the chemical SPT. the assorted conditions to get thin films of metal compound, metallic mineral oxides, binary, ternary and quaternary chalcogenides and superconducting oxides are given. The consequences of precursor, dopants, substrate temperature, post tempering treatments, answer concentration etc., on the physico-chemical properties of those films are given likewise. It's discovered that the properties of thin films rely significantly on the propaedeutic conditions. The properties of the thin film will be simply tailored by adjusting or optimizing these conditions that successively are appropriate for a specific application.

Abstract: (SWH) are becoming increasingly attractive in sustainable development. Hence the Efforts continuously made here is to reduce their costs to make them more affordable. Solar energy has experienced a remarkable development in recent years because of cost reduction due to technological development as well as renewable energy scheme supported by the government. The process of using sun's energy to heat water is not a new technology. (SWH) technology has improved a lot during the past century. The primary method of energy transport in solar energy from sun is electromagnetic radiation .This type of radiation coming from the Sun also depends on temperature. The Sun generates electromagnetic radiation in extensive span of wavelengths. However, most of the radiation is being sent out in the observable range due to its surface temperature. The amount of solar energy received in a particular region depends on the time of the day, the season of the year, the sky's cloudiness, and how closeness of Earth's equator. For modeling we utilized Genetic algorithm and for prediction we employed hybrid ABC and PSO techniques. Genetic algorithm is utilized in order to optimize the modeling technique by using the dataset collected.

Abstract: Many phenomena can be responsible for the attenuation of sound through the suspensions depending on the nature of the particles of the fluid and the frequency range of interest. In particular we can make a distinction between the diffusion mechanisms corresponding to a geometric redirection of the incident wave and the dissipative phenomena, like the thermal and viscous losses. In this work, we are interested in propagation of the ultrasonic waves into suspensions of clay rigid particles with a size between 1 and 50 microns, for which the thermal phenomena and visco-inertial dominate. In this case the dipole diffusion of the wave induced differential motion between the dispersed phase (clay grain) and the continuous phase (distilled water) is coupled to the viscous dissipation in the matching motion of this brake. In this paper, we present the main theories known in calculating the ultrasonic attenuation and velocity coefficient. Such theories permit to take accounts all the orders of interaction, unlike the theoretical of multiple diffusion that remains limited to lower concentrations. Finally, the results calculated by the principal theories will be compared against earlier experimental results obtained from this work.

Keywords: Attenuation measurements, attenuation coefficient, biphasic fluid, theoretical models, calculation of the attenuation and velocity coefficients
