Abstract BENOPT, an optimal material and energy allocation model is presented, which used to assess cost-optimal and/or greenhouse gas abatement of renewable carriers across power, heat transport sectors. A high level detail on the processes from source end service enables detailed life-cycle cost assessments. Pareto analyses can be performed, as well thorough sensitivity analyses. The...

PREMISE OF STUDY Functional trait comparisons provide a framework with which to assess invasion and invasion resistance. However, recent studies have found evidence for both trait convergence and divergence among coexisting dominant native and invasive species. Few studies have assessed how multiple stresses constrain trait values and plasticity, and no study has included direct measurements of...

In this paper, a fuzzy modeling method using genetic algorithms (GAs) with a conciseness measure is presented. This paper introduces De Luca and Termini's fuzzy entropy to evaluate the shape of a membership function, and proposes another measure to evaluate the deviation of a membership function from symmetry. A combined measure is then derived from these two measures, and a new conciseness mea...

A new method for selecting controlled variables (c) as linear combination of measurements (y) is proposed based on the idea of self-optimizing control. The objective is to find controlled variables, such that a constant setpoint policy leads to near optimal operation in the presence of low frequency disturbances (d). We propose to combine as many measurements as there are unconstrained degrees ...

In the Brazilian Amazon, where the forest sector plays a particularly important role in the economy [1], a better understanding of stem volume distribution is necessary to support those who manage forests for wood production during strategic planning, resource allocation and operational decisions. In addition, international agreements are underway for developing global observation systems to as...

In retrospect, it is inevitable that the business world will take notice of experimental economics. Laboratory experiments have become an increasing important tool in economics to study behavior, test policies and provide information to design better mechanisms. On one hand, pioneers such as Vernon Smith and Charles Plott have provided the link between economics theory and actual economics beha...

In the classical maximal flow problem, the objective is to maximize the supply to a single sink in a capacitated network. In this paper we consider general capacitated networks with multiple sinks: the objective is to optimize a general "concave" preference relation on the set of feasible supply vectors. We show that an optimal solution can be obtained by a marginal allocation procedure. An eff...

Though building an AMESim physical model of vehicle three-way catalytic converter (TWC), this article aims to study the light-off characteristics of TWC. By solving the energy and mass conservation equations of gas-solid two phase of the model, this article obtains the emissions conversion rate, such as CO, unburned hydrocarbons (CaHb) and nitrogen oxides (NOx) under different parameters. The r...
