Facilities Planning Process is to achieve mission readiness. The Shore Facility Planning Process is a critical part of the Navy’s process of maintaining land and shore facilities. It precedes the facility programming‚ budgeting‚ funding and implementation phases necessary for prudent management of Navy’s facilities. It is a process that analyzes existing facilities and their conditions; the facilities needed to perform assigned mission; existing facilities use; and how to achieve efficient facility utilization

MICROENCAPSULATION Microencapsulation: Definition: It is the process by which individual particles or droplets of solid or liquid material (the core) are surrounded or coated with a continuous film of polymeric material (the shell) to produce capsules in the micrometer to millimetre range‚ known as microcapsules. Microencapsulation (Cont.): Morphology of Microcapsules: The morphology of microcapsules depends mainly on the core material and the deposition process of the shell. 1- Mononuclear

will do very similar as first part‚ but use the different frequency which is 196 Hz and its multiple times to create a music note from sine waves. For the third part‚ we do a sound cancellation experiment. We will understand the importance of phase in sounds by considering the amplitude. The concepts we will used in this experiment are followed: Fourier theorem: any periodic oscillation curve‚ with frequency f‚ can be broken up or analysed ‚ into a set of simple sine curves with frequencies
