Wind effect on long span bridge
… types of reactions of long span bridge under wind load, such as vortex shedding, flutter and buffeting. Since all of these conditions have the chance to damage bridge structure, we calculate the particular wind speed and magnitude that will maximize the reaction. To check if the theory works …

Capsizing of ships : static and dynamic analysis of wind effect and cost implications
… work presented in this thesis investigates the effect of the wind in rolling and finally capsizing a ship. For the purposes of mechanical analysis, realistic hull forms are used and fundamental issues associated with moments and forces imposed by the wind, are applied. The platforms are examined …

An observational and analytical study of marginal ice zone atmospheric jets
… just above. The three strongest jets had maximum wind speeds at elevations near 350 m to 400 m elevation; one of these jets had a secondary maximum wind height at 900 m. Different theories have been suggested as reasons for the existence of MIZ jets, but in all the cases examined it appeared that …

Surface Circulation and Horizontal Diffusion Processes of the Lower Chesapeake Bay
… hours.</p> <p>The surface current, with local wind effect removed, is seen to be rotary, with the direction of rotation clockwise, and tidally dominated. It does not appear to be significantly influenced by, nor an influence on, the bordering channels with their dominant tidally reversing …

Avionics and control system development for mid-air rendezvous of two unmanned aerial vehicles
… miss distance was analyzed with regard to the wind effect and initial conditions. A series of flight tests was performed using two UAVs which were built as a part of the project. It was demonstrated that each individual aircraft can follow a desired flight path within a position accuracy of 2 …

Revision of European Building Code En1991 for Static and Dynamic Roof Loading by Volcanic Ash
… presents a numerical procedure for testing the effects of both static and dynamic loading of volcanic ash deposition on concrete roofs. The study aims to propose changes by adding additional action (i.e., volcanic ash loads) to the building regulations to make existing and future European …

A NOVEL APPROACH TO NEAR-REAL TIME MONITORING OF VENTILATION RATE AND INDOOR AIR QUALITY IN RESIDENTIAL HOUSES
… are constructed from the driving forces of wind and temperature difference across the building enclosure system, both of which cause pressure differences across the enclosure system for infiltration. The models incorporate other major factors like building leakage characteristics, …

Assessment of irrigation use on crop yield and water supplies in the Midwestern U.S.
… hydrological and agricultural simulations, while wind effect has generally been neglected in previous research. Wind speed is, however, an important factor for many physical processes, including evaporation from soil, and transpiration from plants. In order to investigate how climate variability …

Underwater sound propagation and acoustic communication in a time-varying shallow estuarine environment
… acoustic technology offers a series of effective applications and technical supports for real-time monitoring and long-term preservation of the nature environment and ecosystem in these regions. However, estuaries are shallow waters with complicated temporal and spatial environmental …
