تحسين الإنتاج الزراعي باعتبارات اجتماعية واقتصادية: دراسة حالة من فلسطين, Fathi Annaya
Palestine Technical University Research Journal
Agriculture is not only the main source of income to most Palestinian families; it is also the link to connect them to their valuable land and water resources. Farmers seek assistance from agronomists and decision makers to cultivatethe proper products. In this study, the best selection of agricultural crops is addressed in the multiple-objective context. The study deals with three conflicting objective functions: net benefit, agricultural production, and labor employment. Four-stageprocedure is adopted combining multiple-objective optimization, simple valuation methods, cluster analysis, and multiple criteria decisions making (MCDM) methods. Pareto optimal curves are used to evaluate the marginal prices of both …
An Evaluation Of Tractors Tested At The Nebraska Tractor Test Lab And The Effect Of Epa Emission Standards Based Upon Average Pto Horsepower And Fuel Efficiency, Dalton Erickson
Honors Theses
Newly released tractor models are tested to ensure they meet advertising claims. This thesis utilizes tractor test data to analyze performance trends in tractors based upon their power take off (PTO) horsepower and fuel efficiency and it evaluates how the average fuel efficiency of tractors was affected by the introduction of emission standards by the United States Environmental Protection Agencies. In conclusion, tractors have shown continuous improvement and growth in both fuel efficiency and PTO horsepower, and emission standards have had a small, positive effect on tractors’ average fuel efficiency.
