Models for Source Structure Corrections
At the milliarcsecond scale, most of the extragalactic radio sources exhibit spatially-extended intrinsic structures which are variable in both time and frequency. Such radio structures set limits on the accuracy of source positions determined with the Very Long Baseline Interferometry (VLBI) technique unless their e ects in the astrometric data can be accounted for. We review the modeling sche...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولPropagational Corrections for Basin Structure : Landers Earthquake
Transfer functions appropriate for correcting for propagational distortion caused by basin structures (2D) given a hard-rock (1D) response are developed. The transfer functions are generated theoretically using a hybrid method where the finite-difference technique is employed only in the basin. This allows for efficient computation and the ability to separate path contributions due to body wave...
متن کاملSmall populations corrections for selection-mutation models
We consider integro-differential models describing the evolution of a population structured by a quantitative trait. Individuals interact competitively, creating a strong selection pressure on the population. On the other hand, mutations are assumed to be small. Following the formalism of [17], this creates concentration phenomena, typically consisting in a sum of Dirac masses slowly evolving i...
متن کاملGauge Threshold Corrections for Local String Models
We study gauge threshold corrections for local brane models embedded in a large compact space. A large bulk volume gives important contributions to the Konishi and super-Weyl anomalies and the effective field theory analysis implies the unification scale should be enhanced in a model-independent way from M s to RM s. For local D3/D3 models this result is supported by the explicit string computa...
