We revisit the differential energy distribution of steady-state dynamical models. It has been shown that spherical models does not vary strongly with anisotropy profile, and it is hence mainly determined by density model. explore this similarity in more detail. Through a worked example simple proof, we show mean binding per unit mass ⟨ℰ⟩, or equivalently total integrated B tot = M independent o...
In current research, energy efficiency and technical efficiency of wheat farmers were calculated in Mazandaran province. To estimate technical efficiency the Stochastic Nonparametric Envelopment of Data (StoNED) was used. The model incorporating nonparametric data envelopment analysis model which contain the smoothness and concavity constraints with stochastic frontier analysis model. The requi...
Train braking energy regeneration in urban electrical rail transportation systems can reduce energy consumption and operational cost of the system. In this paper, optimal design of an onboard energy storage system (OESS) with volume constraint is presented for urban electrical rail transportation systems (ERTS). Onboard super-capacitors are considered as the storage system. The objective functi...
the objectives of this study were to determine the energy use efficiency and economical potential of sugar beet production in miandoab city, west azerbaijan province in 2011-12. fields were classified into three groups as group i (less than 1 ha), group ii (1-2 ha), and group iii (more than 2 ha). inputs and outputs data were collected from growers using questionnaire and interview methods. res...
Introduction: In radionuclide imaging, object scatter is one of the major factors leading to image quality degradation. Therefore, the correction of scattered photons might have a great impact on improving the image quality. Regarding this, the present study aimed to determine the main and sub-energy windows for triple energy window (TEW) scatter correction method usin...
Today, energy is known as one of the main factors for the formation and development of industrial societies And the availability of countries to various energy sources represents their potential for political and economic progress. Therefore, the main objective of this study was to investigate the effect of technology factors on the intensity of energy in 29 provinces of Iran (except for Alborz...
