Energy storage is the capture of energy produced at one time for use at a later time. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Common examples of energy storage are the rechargeable battery, which stores chemical energy readily convertible to electricity to operate a mobile phone, the hydroelectric dam, which stores energy in a reservoir as gravitational potential energy, and ice storage tanks, which store ice frozen by cheaper energy at night to meet peak daytime demand for cooling. Fossil fuels such as coal and gasoline store ancient energy derived from sunlight by organisms that later died, became buried and over time were then converted into these fuels. Food (which is made by the same process as fossil fuels) is a form of energy stored in chemical form.

In this thesis, the total fusion cross section sF, the fusion barrier distribution DF and the fusion probability PF, for the reactions 40Ca+44Ca, 40Ar+110Pd, 40Ca+194Pt, 46Ti+46Ti, 48Ti+60Ni, 48Ca+238U, 58Ni+54Fe, 58Ni+58Ni, 81Br+104Ru, 86kr+76Ge, 86kr+100Mo, 124Sn+96Zr, 132Sn+48Ca and 134Te+40Ca has been studied. The semiclassical approach employed in the present study is based on the theory of Alder andWinther (AW) which was originally proposed to treat the Coulomb excitation of nuclei which is called Continuum-Discretized Coupled Channels (CDCC) method. The semiclassical approach uses the Wentzel, Kramers and Brillouin (WKB) approximation to treat the classical fusion probability, whereas that the intrinsic motion is handled as a time-dependent Quantum Mechanics. To sustain our semiclassical calculations and to test its success or shortfall, we had performed full quantum mechanical calculations using the well-known CCFULL code which is used to study the fusion reactions for heavy ions. The calculations for both semiclassical and full quantum mechanical have been performed in the case of no-coupling and in the case of coupling effect included.

Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal proce- ssing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure. As the Electromagnetic and gravi- tational waves are multi-dimensional signals, all the 1-D transformation techniques can be extended for the analysis of these signals as well. Hence this article also discusses multi- dimensional signal processing techniques. In this concern, geophysical survey may use a great variety of sensing instruments, and data may be collected from above or below the Earth's surface or from aerial, orbital, or marine platforms. Geophysical surveys have many applications in geology, archaeology, mineral and energy exploration, oceanography, and engineering. Geophysical surveys are used in industry as well as for academic research. Finally, the sensing instruments such as gravimeter, gravitational wave sensor and magnetometers detect fluctuations in the gravitational and magnetic field.
