Optimization of energy required and greenhouse gas emissions analysis for orange producers using data envelopment analysis approach
TLDR
In this paper, the authors used data envelopment analysis for measuring the efficiency of orchardists, discriminate efficient and inefficient produce from inefficient ones and identify wasteful uses of energy using data envelope analysis for orange production in Guilan province of Iran.About:

Greenhouse gas emissions from different plant production system in China
TL;DR: For the environmental efficiency assessment of the plant nursery production system, the total CO2 eq emissions of 18 nurseries in China was calculated using the LCA "from cradle to gate" approach.

Data envelopment analysis based optimization for improving net ecosystem carbon and energy budget in cotton (Gossypium hirsutum L.) cultivation: methods and a case study of north-western India
TL;DR: In this article, the authors attempted to quantify and optimize C footprints and energy flow in cotton cultivation using integrated Life Cycle Assessment and Data Envelopment Analysis approach to frame policy to reduce C and energy footprints, while enhancing net ecosystem C budget and C sequestration in soils.
Journal Article
Investigation of energy inputs and CO2 emission for almond production using sensitivity analysis in Iran
TL;DR: In this paper, the authors presented a comprehensive picture of the current status of energy consumption and some energy indices like energy use efficiency, energy productivity, specific energy, and net energy gain.
Journal ArticleDOI
A new method for green forage production: Energy use efficiency and environmental sustainability
TL;DR: In this paper , the authors evaluated energy and water use and environmental indicators for hydroponic fodder production in central region of Iran and showed that despite the many benefits of hydroponics on livestock nutrition, its greenhouse cultivation imposes many adverse effects on the environment.

Coefficient alpha and the internal structure of tests.
TL;DR: In this paper, a general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of a test, therefore an estimate of the correlation between two random samples of items from a universe of items like those in the test.

Measuring the efficiency of decision making units
TL;DR: A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs and methods for objectively determining weights by reference to the observational data for the multiple outputs and multiple inputs that characterize such programs.

Some Models for Estimating Technical and Scale Inefficiencies in Data Envelopment Analysis
TL;DR: The CCR ratio form introduced by Charnes, Cooper and Rhodes, as part of their Data Envelopment Analysis approach, comprehends both technical and scale inefficiencies via the optimal value of the ratio form, as obtained directly from the data without requiring a priori specification of weights and/or explicit delineation of assumed functional forms of relations between inputs and outputs as mentioned in this paper.

Data Envelopment Analysis: A Comprehensive Text with Models, Applications, References and DEA-Solver Software
TL;DR: In this article, the basic CCR model and DEA models with restricted multipliers are discussed. But they do not consider the effect of non-discretionary and categorical variables.

Carbon emission from farm operations
TL;DR: The available information on energy use in farm operations, and its conversion into carbon equivalent (CE) is a synthesis of the available information and shows that an output/input ratio, expressed either as gross or net output of C, must be >1 and has an increasing trend over time.
