Parameterization of sea surface drag under varying sea state and its dependence on wave age

Kumar, R. Rajesh; Kumar, B. Prasad; Satyanarayana, A.; … - In: Natural Hazards 49 (2009) 2, pp. 187-197

Momentum and energy exchange at air–sea interface through wind stress is very important for air–sea interaction studies, ocean modeling, and climate studies. The accurate representation of wind stress, in terms of drag coefficient, is a key factor in estimating the momentum transfer at the...

Optimal design and operation of a wastewater purification system

Alvarez-Vázquez, Lino J.; Balsa-Canto, Eva; Martínez, … - In: Mathematics and Computers in Simulation (MATCOM) 79 (2008) 3, pp. 668-682

Due to the importance of coastal areas, is of the highest interest to implement purification systems that with minimum cost are able to assure water quality standards in agreement with the regional legislations. This work addresses the optimal design (outfall locations) and optimal operation...

Subjective Beliefs and Schooling Decisions

Belzil, Christian - Institute for the Study of Labor (IZA) - 2007

This paper considers the estimation of sequential schooling decisions made by agents who are endowed with subjective beliefs about their own ability. I use unique Italian panel data which provide information on i) the curvature of the per-period utility function, ii) schooling decisions, iii)...

Genericity analysis of split bifurcations

Kung, Fan-chin - EconWPA - 2004

This paper analyzes the genericity of bifurcations of one-parameter families of smooth (C1) vector fields that are embedded in an underlying multi-dimensional parameter space. Bifurcations with crossing equilibrium loci are called 'split bifurcations.' They include, for example, the pitchfork...
