The aim of this study is to investigate the context by which veterinary services may affect technical efficiency (TE) of Iranian dairy farms. A data envelopment analysis (DEA) was applied to a random sample of 840 dairy farms from six provinces across Iran to estimate regional frontier and metafrontier production functions and also to calculate corresponding TE of these farms. The relationship ...

We consider the high order moments estimator of the frontier of a random pair, introduced by Girard, S., Guillou, A., Stupfler, G. (2013). Frontier estimation with kernel regression on high order moments. In the present paper, we show that this estimator is strongly uniformly consistent on compact sets and its rate of convergence is given when the conditional cumulative distribution function be...

this paper is concerned with the estimation of frontier production function to measure the technical efficiency for iranian textile companies during 1995. the objective of this estimation is to investigate if there are any differences in the technical efficiency between the private and public firms as well as the relationship between technical efficiency and size of textile companies in iran. a...

A stochastic cost equation was estimated for US dairy farms using national data from the production year 2000 to determine how farmers might reduce their cost of production. Cost of producing a unit of milk was estimated into separate frontier (efficient) and inefficiency components, with both components estimated as a function of management and causation variables. Variables were entered as im...

There arises situations where an autonomous robot needs to navigate to a target location and no information is available about the terrain. Frontier based navigation is one of the most efficient methods of exploration and navigation for such situations. In a frontier based strategy, the robot navigates to the target location by detecting intermediate frontier regions, which are points lying on ...

The paper introduces an exclusion/inclusion fuzzy classification neural network. The network is based on our GFMM [3] and it allows for two distinct types of hyperboxes to be created: inclusion hyperboxes that correspond directly to those considered in GFMM, and exclusion hyperboxes that represent contentious areas of the pattern space. The subtraction of the exclusion hyperboxes from the inclu...
