How Much Do Helioseismological Inferences Depend on the Assumed Reference Model?
We investigate systematic uncertainties in determining the proÐles of the solar sound speed, density, and adiabatic index using helioseismological techniques. We Ðnd that rms uncertainties (averaged over the Sun) of D0.02%È0.04% are contributed to the sound-speed proÐle by each of three sources : (1) the choice of assumed reference model, (2) the width of the inversion kernel, and (3) the measu...
متن کاملHow much do helioseismological inferences depend upon the assumed reference model ?
We investigate systematic uncertainties in determining the profiles of the solar sound speed, density, and adiabatic index by helioseismological techniques. We find that rms uncertainties — averaged over the sun — of ∼ 0.02%− 0.04% are contributed to the sound speed profile by each of three sources: 1) the choice of assumed reference model, 2) the width of the inversion kernel, and 3) the measu...
متن کاملHow much do you believe?
This paper responds to a number of criticisms of Dempster-Shafer theory made by Judea Pearl. He criticises Dempster-Shafer belief for not obeying the laws of Bayesian belief," however, these laws lead to well-known problems in the face of ignorance, and seem unreasonably restrictive. It is argued that it is not reasonable to expect a measure of belief to obey Pearl's sandwich principle. The sta...
متن کاملHow much do Workers Search ?
In this paper, I consider four determinants of wages: productivity, workers’ bargaining power, competition between employers due to on-the-job search, and search intensity by workers. Workers can increase their job offer arrival rate through costly search. Employers take into consideration the search intensity choices of their employees when the two parties jointly set wages. Using a Nash barga...
