Brazil has one of the most extensive public program for organ transplantation in the world, and the Brazilian National Health System (SUS) provides full coverage procedures related to organ donation, transplants, and post-transplant. Despite the relevance of the subject and the existence of long...

This paper attempts to find the optimal formation of three midfielders and three forward football players on ground, using the classic Quadratic Assignment Problem or Facility Layout problem. Players are treated as “machines”, their positions as locations, and the flow of materials between...

A cake is a metaphor for a heterogeneous, divisible good. When two players divide such a good, there is always a perfect division—one that is efficient (Pareto-optimal), envy-free, and equitable—which can be effected with a finite number of cuts under certain mild conditions; this is not...

A cake is a metaphor for a heterogeneous, divisible good, such as land. A perfect division of cake is efficient (also called Pareto-optimal), envy-free, and equitable. We give an example of a cake in which it is impossible to divide it among three players such that these three properties are...

In this study we evaluate the profitability of nutrient abatement measures in eutrophied coastal areas exposed to a risk of frequent oil spills. The case studied is the Gulf of Finland, which forms part of the Baltic Sea.We present a dynamic model that integrates land loads of nitrogen and...

Increasing shares of wind and solar generation serve to decarbonize electricity generation; however, their temporal and spatial variability poses challenges in grid operation. While grid expansion is restricted in the medium term, storage technologies can potentially increase the power systems'...

Environmental cost-benefit analysis (ECBA) refers to social evaluation of investment projects and policies that involve significant environmental impacts. Valuation of the environmental impacts in monetary terms forms one of the critical steps in ECBA. We propose a new approach for environmental...

The study analyzed the growth of agricultural activity in the Amazon region and the consequent increase in deforestation. In addition, it was investigated whether the difference in land productivity observed in agriculture in the region of the Legal Amazon can be justified by low efficiency and,...

Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...

In this article we analyze the remuneration mechanism for the reduction of energy losses, through a dynamic principal-agent model in continuous time. The agent represents the power distribution company, which makes investments, or in other words, makes an effort to reduce energy losses. The...
