The intention is to develop a numerical method to assess the seakeeping characteristics of a surface-effect ship (ses). this would result in a computer program which properly considers the unique complexities of an ses. the complexities include, but are not limited to, the hydrodynamics, the… More

The intention is to investigate the ship motion effects on robot dynamics and equipment life. the on-board robot is equivalent to a stationary robot with base excitation due to ship motion. the excita-tion at the robot base will be monitored either by placing gyroscopes and accelerometers at that… More

Military systems powered by internal combustion engines emit noise from the exhaust system. there are two types of noise, airborne, due to the pressure wave propagating through the exhaust system and exiting at the outlet and structure - borne, radiated from the vibrating components of the exhaust… More

There is an increased emphasis on the acoustic signatures of ground combat vehicles due to the development of new and effective acoustic target acquisition systems. during the design stage of a ground combat vehicle, it is important to reduce the noise, emitted from structural components. therefore,… More

In the proposed work a complete elastic porous material theorywill be used as a basis for developing the first two-dimensionalacoustical finite element model of noise control foams. Althoughfoams are widely used for passive control of aircraft andaut
