A wave-splitting based optimization approach to multi-dimensional time-domain electromagnetic inverse problems

Gustafsson, Mats; He, Sailing - In: Mathematics and Computers in Simulation (MATCOM) 50 (1999) 5, pp. 541-551

An optimization approach to a multi-dimensional electromagnetic inverse problem in the time domain is considered. Wave …-splitting is integrated in the optimization algorithm. An analysis based on energy estimates is given to show that the wave … conductivity are reconstructed by minimizing an objective functional. An explicit expression for the gradient of the objective …

Income volatility and health

Halliday, Timothy J. - 2007

We investigate the impact of exogenous income fluctuations on health using twenty years of data from the Panel Study of Income Dynamics using techniques from the literature on the estimation of dynamic panel data models. Contrary to much of the previous literature on health and socio-economic...

Heterogeneity, state dependence and health

Halliday, Timothy J. - 2008

We investigate the evolution of health over the life-cycle. We allow for two sources of persistence: unobserved heterogeneity and state dependence. Estimation indicates that there is a large degree of heterogeneity. For half the population, there are modest degrees of state dependence. For the...

Earnings growth and movements in self-reported health

Halliday, Timothy - 2012

We employ data from the Panel Study of Income Dynamics to investigate income to health causality. To account for unobserved heterogeneity, we focus on the relationship between earnings growth and changes in self-reported health status. Causal claims are predicated upon appropriate moment...
