Design The feasibility study, focuses on building up knowledge of and experience with the technology of using the "d31-effect" of piezoelectric material to damp the internal vibrations of the system. The investigation starts by specifying the mathematical relations that describes the piezoelectric "d31-effect" and particularising these relations for the actuator and sensor situation. The two vi...

A wide range of nonlinear optical coefficients and various systems of notation have been used to describe optical second-harmonic generation (5MG). To avoid possible confusion, the techniques of optical nonlinear coefficient measurement and the elementary theory of SHG are briefly reviewed. Absolute and relative nonlinear coefficient measurements by phase-matched SHG are described. The followin...

A dynamic microsimulation model of cohort earnings based on the Australian population aged between 20 and 55 years is described. A highly parsimonious modular structure is adopted to facilitate sensitivity analysis and enable additional characteristics to be added, should they be desired. Despite the restrictive specifications used, the model closely reflects the data used for calibration. JEL ...

This research focuses on the synthesis and characterization of a piezoelectric (β-CN)APB/ODPA polyimide. The remanent polarization and piezoelectric d31 and g33 coefficients are reported to assess the effect of synthesis variations. Each of the materials exhibits a level of piezoelectricity which increases with temperature. The remanent polarization is retained at temperatures close to the glas...

We examine the association of income variability both within and across generations based on a heterogeneous growth model of permanent and transitory income in Sweden. Non-parametric regressions reveal that income variability is strongly associated with long-run levels of income, especially for lowand highincome earners, and that it is also strongly associated across generations. JEL Classifica...

The steady rise in income and wealth inequality the last four decades, together with evolution of a vanishing middle class, has raised concerns about potentially pernicious effects these trends on social stability economic growth. This paper evaluates possibility designing tax systems aimed at reducing bipolarization. Using two fundamentally different metrics, we provide unified foundation prog...

We document the intergenerational mobility of Black and White American men from 1880 through 2000 by building new historical datasets for late nineteenth early twentieth century combining them with modern data to cover middle century. find large disparities in mobility, children having far better chances escaping bottom distribution than every generation. This gap was more important proximately...

We note some problems in Alesina and Angeletos (2005) and suggest a way to maintain the key insight of that paper, which is that a demand for fairness could lead to di¤erent economic systems such as those observed in France versus the US (multiple equilibria). JEL classi…cation: D31, E62, H2, P16.
