bootstrapping the dea is one of the current methods of measuring robust efficiency by constructing a confidence interval and measuring the noise (bias) in production. in this study, two estimators: the conventional data envelopment analysis (dea) and bootstrap simulation with 2,000 bootstrap iterations were applied on a cross sectional data of 296 broiler farms in peninsular malaysia. the objec...
Organic agriculture addresses the public demand to diminish environmental pollution of agricultural production. Until now, however, only few studies tried to determine the integrated environmental impact of conventional versus organic production using life cycle assessment (LCA). The aim of this article was to review prospects and constraints of LCA as a tool to assess the integrated environmen...
One of the basic components of future distribution networks are renewable energy resources (RER). The uncertainty in power production of renewable resources such as wind and solar as well as load is another characteristic of such networks. Conventional power flow methods as a basic tool for power system studies may not be suitable for active distribution networks such as microgrids. In this pap...
To study the effects of tillage system, planting method and of nitrogen fertilizer rate on the agronomic characteristics and seed yield of rapeseed (Brassica napus L.) Dalgan oilseed rape cultivar, as the second crop after rice, a split factorial experiment in complete randomized block design with three replications was carried out in two cropping seasons (2016-2018) at paddy fields of Rice Res...
background: conventional health, safety and environment (hse) are a widely used approach to enhance availability and efficiency of complex systems. the integrated hsee system is defined however as integration of conventional hse with ergonomics approach. the presented hsee system introduces a unique, effective and systemic mechanism, which integrates the structure of the human and organizationa...
The island of Sicily has a long standing tradition in citrus growing. We evaluated the sustainability of orange and lemon orchards, under organic and conventional farming, using an energy, environmental and economic analysis of the whole production cycle by using a life cycle assessment approach. These orchard systems differ only in terms of a few of the inputs used and the duration of the vari...
