Developing a disturbance source characterization technique for small satellite applications
… a framework with which to characterize candidate sources of disturbance for small satellite applications. By characterize we mean estimate disturbance source vibrational frequencies, and by candidate sources we mean sources previously determined with the ability to induce micro-vibrations. This …

Active control of coupled wave propagation in fluid-filled elastic cylindrical shells
… occurs. For various types of harmonic disturbance, this study demonstrates that, whether the propagating energy is predominantly conveyed in the shell or in the fluid, large attenuations of the total power flow may be achieved by using an active control approach. As the shell and fluid …

Factors Driving Recreational Disturbance of Waterbirds on the Texas Coast
… last fifty years. During this time, recreational disturbance to avian species has increased through human development and activities, resulting in a decrease in bird populations. While many recreationists may believe that mortality is the only type of harmful disturbance, direct and indirect …

The effects of human disturbance and climatic conditions on breeding Cassin’s auklets
Human disturbance has been observed to have effects on wildlife. These effects can be either positive or negative, depending on the study species; however, most of the research done to date has demonstrated negative effects that are reflective in the behaviour and reproductive biologyof the …
