researchers of language teaching believe that teaching method has a lot of impact on the speed and depth of learning. the importance of this is so obvious on teaching some persian language structures which are syntactically and semantically complicated. one of these structures is conditional sentences which has been considered in this study. here we tried to teach conditional sentences via both...

In this paper we investigate the finite sample performance of four estimators that are currently available for additive nonparametric regression models the backfitting B-estimator, the marginal integration M-estimator and two versions of a two stage 2S-estimator, the first proposed by Kim, Linton and Hengartner (1999) and the second which we propose in this paper. We derive the conditional bias...

In this paper we present a 3D semantic outdoor mapping system with multi-label and resolution octree maps based on the OctoMap mapping framework. The semantic labeling of point clouds uses conditional random fields. Speeding up the conditional random field, we use an adaptive graph downsampling method based on voxel grids and the histogram-of-oriented-residuals operator to describe the local po...

This paper provides new evidence on the dynamics of equity risk premia in euro area stock markets across country and industry portfolios. We develop and estimate a conditional intertemporal CAPM where returns on aggregate euro area, country and industry portfolios depend on the market risk as well as on the risk that the investment opportunity set changes over time. Prices of risks are time-var...

There is a large variety of Local Linearization (LL) schemes for the numerical integration of initial value problems, which differ with respect to the algorithm that is used in the numerical implementation of the Local Linear Discretization. However, in contrast with the LL Discretization, the order of convergence of the LL schemes have not been studied. In this paper, a general theorem about t...

Abstract This paper applies a two-stage nonparametric approach to compare companies operating in different business models the global semiconductor industry. Using panel data over 1999–2018 on 470 industry, we explore performance of conditional capital investment and between integrated device manufacturers fabless-foundry model. We find that vertically are constrained heavily by investment. Dis...
