In this paper, a multi-objective power dispatching problem that uses Plug-in Electric Vehicle (PEV) as storage units is considered. The problem involves several PEVs and a microgrid community, composed of small houses, residential areas, and different Renewable Energy Resources. Three different objectives are considered: microgrid total costs; usage of PEV batteries and maximum grid peak load. In order to find sets of non-dominated solutions, a matheuristic black box solves several Mixed Integer Linear programming (MILP) subproblems. We improve a previously developed MILP model and design a new multi-objective matheuristic including new problem initialization mechanisms.
In this work we study the role of fluorine for the selective suppression of porous silicon in localized SOI applications. The formation of porous silicon can be done selectively by controlling the Fermi level in areas...

The FALCON development environment was designed around three basic data representations: scalars, vectors, and dense matrices. Utilizing the FALCON interactive restructuring system, the environment has been enhanced to allow the identification of structures within sparse matrices, such as diagonal matrices or symmetric matrices, and the use of this information for improving performance of the generated code. In addition, the environment supports the modification of the representation of the data. Such modifications have been shown to provide significant performance improvements.

This paper provides an evaluation of the effects of using the Kumon method for supplementing the teaching of mathematics in the inner-urban school district of Pontiac, Michigan. Michigan Educational Assessment program (MEAP) test scores are cited for Herrington, Owen, and Crofoot elementary schools, which used the Kumon program during part of their ninety minutes of daily mathematics instruction, and demographically matched Emerson Elementary School, which did not use the Kumon program during its ninety minutes of daily mathematics instruction. In 2003, Emerson had 4.5% of its students exceed Michigan standards. In 2004 that number was 8.6%. At Herrington Elementary School, however, the MEAP scores rose from 39.7% to 89.1% of students exceeding state standards during the same single year period. Crofoot went from 0.0% of students exceeding Michigan state standards in 2003, to a remarkable 58.1% exceeding standards in 2004. Owen also showed substantive improvements. The research project, a joint effort between Oakland University's School of engineering and the School District of Pontiac, reveals that supplementation with the Kumon method as a partial replacement for a traditional mathematics program appears to result in significant improvements in statewide Michigan Educational Assessment program test scores for mathematics.
Implicit discourse relation recognition is a challenging task due to the absence of the nec-essary informative clue from explicit connec-tives. The prediction of relations requires a deep understanding of the semantic...

Ultrasonic backscatter can provide information on the density of scatterers within biological media, and is therefore an important tool in tissue characterization. In this paper, a novel neural network approach to estimate scatterer density from generalized entropy is proposed. Neural estimation compares favorably with nonlinear least-squares models.

We consider the optical properties of finite systems composed of a series of graphene sheets separated by thin dielectric layers. Because these systems respond as conductors to electric fields in the plane of the graphene sheets and as insulators to perpendicular electric fields, they can be expected to have properties similar to those of hyperbolic metamaterials. We show that under typical experimental conditions graphene/dielectric multilayers have enhanced Purcell factors, and enhanced photonic densities of states in both the terahertz (THz) and midinfrared (mid-IR) frequency range. These behaviors can be traced to the coupled plasmon modes of the multilayer graphene system. We show that these results can be obtained with just a few layers of graphene.
