This note studies the response of a simple linear baroclinic coastal-upwelling model to fluctuating longshore winds. Correlations between wind stress and velocities are computed explicitly. It is shown that these correlations depend primarily upon the wind-~ spectrum and that. for a realistic spectrum, the wind stress leads the longshore velocity by approximately one day. The computed correlati...

A formal asymptotic analysis of two classes of phase field models for void growth and coarsening in irradiated solids has been performed to assess their sharp-interface kinetics. It was found that the sharp interface limit of type B models, which include only point defect concentrations as order parameters governed by Cahn-Hilliard equations, captures diffusion-controlled kinetics. It was also ...

like other developing countries, iranian cities are growing and expanding physically at a high speed. for about five decades, the only policy of the urban development plans in the field of urban growth management has been definition of the urban growth boundary (u.g.b.) which is still used without any major modifications.despite the slight evidences indicating the ineffectiveness of the current...

The increasing cost of peanut production is a major concern in Iran. Therefore, developing the mechanization of peanut production is a necessity. In this regard, a three-phase Delphi study was conducted to identify the promoting and deterring factors affecting peanut cultivation mechanization in Guilan Province, the main peanut-producing region in Iran. After preliminary studies, 26 experts wer...

The Kraljic matrix has been largely used in many different industries as an efficient tool for developing differentiated purchasing strategies. However, its application on construction industry is unknown, as well as the lack of systematical approach on criteria prioritization which is one of the key issues of the methodology. This paper describes the application of Kraljic matrix on a large co...
