The Limits of political compromise: debt ceilings and political competition
(2015)
We study the desirability of limits on the public debt and of political competition in an economy where political parties alternate in office. Due to rent-seeking motives, incumbents have an incentive to set public ...
Co-limitation and stoichiometry capture the interacting effects of nitrogen and sulfur on maize yield and nutrient use efficiency
(Elsevier Science, 2020-02)
Nitrogen (N) and sulfur (S) deficiencies, individually and in combination, produce gaps between actual and potential yields in maize (Zea mays L.). Our objectives were to evaluate the effect of N and S status and their ...
Constrained efficiency without commitment
(Elsevier Science Sa, 2015-12)
We consider an infinite horizon economy where agents share income risks by trading a complete set of contingent claims but cannot commit to their promises. Allocations are restricted to be self-enforcing relative to autarchic ...
Magnetically-driven quantum heat engines: the quasi-static limit of their efficiency
(2016)
The concept of a quantum heat engine (QHEN) has been discussed in the literature, not only due to its intrinsic scientific interest, but also as an alternative to efficiently recover, on a nanoscale device, thermal energy ...
Water use, water limitation, and water use efficiency in a Eucalyptus plantation

An efficient implementation of tabu search in feeder reconfiguration of distribution systems
(2012-12-11)
This paper presents an efficient tabu search algorithm (TSA) to solve the problem of feeder reconfiguration of distribution systems. The main characteristics that make the proposed TSA particularly efficient are a) the way ...
Efficiency Measurements in Induction Motors: Comparison of Standards
(Institute Of Electrical And Electronics Engineers, 2015-08)
Recently, given the need to reduce the emission of greenhouse effect gases and limiting the steady increase in energy demand, were have proposed new standards of efficiency levels of electric motors. From them have been ...
