The need for Zero Emission and clean energy vessels has been a major importance in the recent years. The aim of the paper is to design and size the battery system for Luxury yachts and Ferries using the Li-ion battery technology. The evolution of the battery technology in the last decade made the yacht / ferry owners to implement the battery technology to the electric vessels. This paper discusses the step by step approach for the battery system arrangement, sizing of the battery racks, selection of the cooling systems for batteries, effect on stability, cost, safety and design life of the batteries. In this paper it summarizes the cost benefit analysis of the battery system for the electric yacht / ferry when compared to a conventional diesel / hybrid propulsion system.

This paper was written to guide educators in the selection of computer systems for instructional applications. Four systems representing different cost categories are compared via a set of twenty-five parameters. Besides the PLATO system, the other three computer systems are different capability microcomputers. The approach of this study was to compare computer systems by enumerating the costs and benefits. Problems associated with the cost-benefit analysis are also discussed.

Due to the high organic fraction in municipal solid waste (MSW) composition in Mexico City, anaerobic digestion (AD) is considered as a viable treatment method for organics in this study. The most feasible way refers to the waste from the wholesale market Central de Abasto, which is predominantly organics. This work aims to perform a business plan and discuss the barriers for AD technology in Mexico. In this case study, the cost-benefit analysis (CBA) approach is applied to estimate the profitability of the project. The net present value of this project is positive, and the model resulted in a payback period of 7 years. Identified barriers to feasibility of energy generation through biogas of MSW in Mexico include the need for large investment, low profitability through sales of electricity, and no use for generated heat. An attractive panorama for clean energy in Mexico was not evidenced, even though the Energy Reform took place in 2013. However, the environmental analysis also demonstrates a positive environmental impact of 730 kg CO2 per 1 Mg of MSW. Therefore, support incentives are needed to promote the use of other by-products of the AD process, such as heat and digestate.

This article analyzes definitions and the role of hostile takeovers at the Russian and European markets for corporate control. It develops the methodology of assessing the efficiency of anti-takeover defenses adapted to the conditions of the Russian market. The paper uses the cost-benefit analysis, where the costs and benefits of the pre-bid and post-bid defenses are compared.

Many countries are investing in measures to improve surface water quality, but the investment programmes for so doing are increasingly becoming subject to cost-benefit analysis. Whilst the cost of control measures can usually be determined for individual improvement schemes, there are currently no established procedures for valuing the benefits attributable to improved surface water quality. The paper describes a methodology that has been derived that now makes this possible.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

In 1985, Boehlert (Fish. Bull. 83: 103–117) suggested that fish age could be estimated from otolith measurements. Since that time, a number of inferential techniques have been proposed and tested in a range of species. A review of these techniques shows that all are subject to at least one of four types of bias. In addition, they all focus on assigning ages to individual fish, whereas the estimation of population parameters (particularly proportions at age) is usually the goal. We propose a new flexible method of inference based on mixture analysis, which avoids these biases and makes better use of the data. We argue that the most appropriate technique for evaluating the performance of these methods is a cost–benefit analysis that compares the cost of the estimated ages with that of the traditional annulus count method. A simulation experiment is used to illustrate both the new method and the cost–benefit analysis.
