This paper presents a new methodology to accurately characterize and predict the annual variation of wind conditions. The estimate of the distribution of wind conditions is necessary to quantify the available energy (power density) at a site, and to design optimal wind farm configurations. A...

A new methodology, the Unrestricted Wind Farm Layout Optimization (UWFLO), that addresses critical aspects of optimal wind farm planning is presented in this paper. This methodology simultaneously determines the optimum farm layout and the appropriate selection of turbines (in terms of their...

A Response Surface-Based Wind Farm Cost (RS-WFC) model is developed for the engineering planning of wind farms. The RS-WFC model is developed using Extended Radial Basis Functions (E-RBF) for onshore wind farms in the U.S. This model is then used to explore the influences of different design and...

Particle Image Velocimetry from the centerline of a 3 × 5 scaled down array of wind turbines in a wind tunnel was analyzed to gain further understanding of how turbulent transport brings mean kinetic energy (MKE) into the array from the neutrally stable Atmospheric Boundary Layer (ABL) above....

Objectives To measure the economic burden of cerebral palsy (CP) in China is to provide information on CP's societal impacts to policy-makers.Methods The economic burden of CP includes direct healthcare costs, direct non-healthcare costs, developmental costs and indirect costs such as...

This paper analyzes intergenerational earnings mobility in a model where human capital is produced using schooling and parental time. In steady -states more mobile societies have less inequality, but in the short-run higher mobility may result from an increase in inequality. Starting from the...

In previous studies, taxing income or consumption hinders long-run growth. Incorporating saving and leisure into the non-scale Schumpeterian model of Howitt (1999), we show that the usual growth effects of taxing consumption and labor income do not exist.

This paper examines the problem of optimal tax mix analytically in a two-sector growth model with transitional dynamics. Tax revenue is required to provide a pure public good. The key problems are: over-consumption of leisure under labor income or consumption taxes; and under-investments in...

In this paper we explore the implication of a morbidity risk for the relationship between longevity and annuitization. We divide old-age life into two periods with uncertain survival from the end of the first to the end of the second. We show that a rise in the survival rate causes different...
