Advanced Energy and Sustainability Research, EarlyView.Less metal, more distance! The ReOx‐Pd/CeO2 catalyst, an active heterogeneous catalyst for the consecutive deoxydehydration and hydrogenation of vicinal diol, suffers a gradual loss of activity throughout its use due to the polymerization of monomeric ReOx active species.

Why we like the ECI+ algorithm [PDF]
arXiv, 2017 Recently a measure for Economic Complexity named ECI+ has been proposed by Albeaik et al. We like the ECI+ algorithm because it is mathematically identical to the Fitness algorithm, the measure for Economic Complexity we introduced in 2012. We demonstrate that the mathematical structure of ECI+ is strictly equivalent to that of Fitness (up to ...

Mathematical modelling and economic evaluation
Mathematical Modelling, 1987 AbstractIn small developing countries many significant agroindustrial projects are not marginal. Therefore a model is proposed that includes all the main components of the sector. This model can be used to evaluate new projects, policies, to test the prevailing degree of market imperfection in the sector and in general to provide a better understanding

Incerteza e não ergodicidade: crítica aos neoclássicos
Brazilian Journal of Political Economy, 2014 The starting point of this essay is to show that, in our view, the problem of the traditional economics is not in the deductive method nor the mathematical methods used, but to attribute to economic agents "power" on the future and prescribe the ...

Mathematical Models and Economic Forecasting: Some Uses and Mis-Uses of Mathematics in Economics [PDF]
, 2012 We consider three cases studies of the uses and mis-uses of mathematics in 8 economics and econometrics. The first concerns economic forecasting, where a 9 mathematical analysis is essential, and is independent of the specific forecast- 10 ing model and how the process being forecast behaves.

Advanced Energy and Sustainability Research, EarlyView.The study discusses synthesis strategies of metal‐free heteroatom‐doped nanocarbon materials from biomass for use in rechargeable zinc–air batteries. It also covers the significance of these materials as electrocatalysts and electrodes for improving the oxygen reduction and evolution reactionsin.

Computation in Economics [PDF]
This is an attempt at a succinct survey, from methodological and epistemological perspectives, of the burgeoning, apparently unstructured, field of what is often – misleadingly – referred to as computational economics.
