Research ArticleOpen accessIn the keywordsOptimal Subsurface Appraisal: A Key Link to the Success of Development Projects-Few ExamplesVirendra Singh, Ivan Yemez, Elena Izaguirre, Alvaro RaceroDuring exploration and production phases, the life of a hydrocarbon field can be distinguished by five main stages: Exploration, appraisal, development, production and abandonment. Of particular interest is the appraisal stage, where billions of dollars are spent across the oil and gas industry on data gathering activities with a view to reducing subsurface uncertainties towards optimizing reservoir development and management. … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 13 Jan 2017 · 8,516 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Hydroponic Production of Vegetables and Ornamental Pot-Plants in a Heated Greenhouse in Western Macedonia, GreeceIoannis I. Papadopoulos, Fotis Chatzitheodoridis, Christos Papadopoulos et al.In this research an evaluation-in terms of investments-of hydroponics greenhouses is carried out, as well as the possibility of the development of greenhouse crops cultivations, such as vegetables and flowers, in them is explored in Western Macedonia. The survey was realized between the years 2002-2006, in a model greenhouse, which was installed by the Public Power Corporation S.A., in soils … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Use of Real Options Methodology to Pasturelands EvaluationA. Michailidis, F. Chatzitheodoridis, I. Mountousis, K. PapanikolaouThis study demonstrates the utility of the real options approach to pasturelands investment analysis. The main objectives are to discuss the real options theory and show how it can be adopted to model uncertainty and managerial flexibility in pasture management (enlargement plan) and investment. Secondly, we show how to calculate the option values of selected options that may be available … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 6,763 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Biogas Plants by the Application of an Internal Rate of Return and Debt Service Coverage ApproachGiuseppe Bonazzi, Mattia IottiEnergy production using renewable energy has an effect on environmental sustainability and on public expenditure. In fact, this industry is heavily assisted by public support from the European Union and the Italian State. Developing and applying a method to evaluate the return on investment for companies operating in the field of renewable energy allows them to quantify their efficient use … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 6 Apr 2015 · 7,632 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstablishing an Adaptive Production-Procurement System with Markov Chain Approach Associated with 3C TheoryChun-Ta LinProblem statement: In this study, we classify the imperfect situations that the unreliability of production and the defective products might be incurred from production process into eight independently recurrent categories. Approach: With the property of recurrence of Markov chain, the limiting probability of each imperfect production category can be calculated through the transition probabilities matrix generated from these imperfect production … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,352 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstimating the Optimal Farm Size under Uncertainty: an Application of Real Options MethodologyAnastasios Ch. Michailidis, Konstadinos A. MattasFarm structure and optimal farm size have always attracted the interest of research as they constitute some of the intense problems of farm efficiency and farm income. Although several approached have been employed to handle with this problem a real options approach can significantly contribute on this matter. This article provides an empirical example of applying real options approach in … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 7,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Evaluation of Standalone Hybrid PV–H2 with Storage SystemAdeyinka Victor Adebayo, Samuel Oladeji, Hussein Kehinde Adebayo, Ismaheel Oyeyemi OladejoThis study evaluates the economic performance of a standalone hybrid PV-H2 system with battery storage for small-scale electricity demand. The methodology involves comparing various configurations of standalone PV, storage, and hybrid PV-H2 systems under different discount rates and evaluation periods. Economic indicators such as Net Present Value (NPV), Payback Period, and Discounted Annualized Return (AAR) determine financial viability. Results indicate … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 4 Mar 2025 · 7,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Postoperative Brain MRI Segmentation with Automated Skull Removal and Resection Cavity AnalysisSobha Xavier P., Sathish P. K., Raju G.Brain tumors present a significant medical challenge, often necessitating surgical intervention for treatment. In the context of postoperative brain MRI, the primary focus is on the resection cavity, the void that remains in the brain following tumor removal surgery. Precise segmentation of this resection cavity is crucial for a comprehensive assessment of surgical efficacy, aiding healthcare professionals in evaluating the … …Journal of Computer Science, Vol. 20, Issue 5 · 19 Mar 2024 · 5,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractProductive and Economic Performances of Magelang Duck Fed on Fermented Kariba WeedAgus Setiadi, Siswanto Imam Santoso, Edjeng Suprijatna et al.The duck farming business faces the high feeding costs problem. Kariba Weed (KW) is an alternative feed that has been widely used as a source of ducks' feeding materials. However, a problem exists because KW contains high crude fibre. Fermented KW that contains microbes will reduce the crude fibre content, leading to a good quality of duck meat. This study … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 21 Nov 2021 · 6,561 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganic Fertilizers: An Agroecological and Commercial Bet On Smallholders in the Sumapaz RegionElizabeth Ann Escobar Cazal, Taha Ahmadi, Diego Fabián Bejarano Morales et al.The feasibility of an agroecological project is supported, among other factors, by the cost-benefit relationship, which tends to shift profitability paradigms on organic fertilizers within the context of long-term finances. For this purpose, the objective of this paper is to carry out a financial study to market organic fertilizers (compost and vermicompost) in the Sumapaz region. An initial analysis of … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 29 Jul 2020 · 6,991 accessesView PDFCite
