Everything should be made as simple as possible, but not simpler.

The paper presents a novel approach for accurate polygonization of implicit surfaces with sharp features. The approach is based on mesh evolution towards a given implicit surface with simultaneous control of the mesh vertex positions and mesh normals.

Quantified Boolean formulas (QBF) provide a powerful framework for encoding problems from various application domains, not least because efficient QBF solvers are available. Despite sophisticated evaluation techniques, the performance of such a solver usually depends on the way a problem is represented. However, the translation to processable QBF encodings is in general not unique and may eithe...

In this paper, we examine the problem of "blocked online bipartite matching". This problem is similar to the online matching problem except that the vertices arrive in blocks instead of one at a time. Previously studied problems exist as special cases of this problem; the case where each block contains only a single vertex is the standard online matching problem studied by Karp et al. (1990), a...

This paper presents a systematic study on the properties of blocked linear systems that have resulted from blocking discrete-time linear time invariant systems. The main idea is to explore the relationship between the blocked and the unblocked systems. Existing results are reviewed and a number of important new results are derived. Focus is given particularly on the zero properties of the block...

Bacteria and plant derived volatile organic compounds have been reported as the chemical triggers that elicit induced resistance in plants. Previously, volatile organic compounds (VOCs), including acetoin and 2,3-butanediol, were found to be emitted from plant growth-promoting rhizobacteria (PGPR) Bacillus subtilis GB03, which had been shown to elicit ISR and plant growth promotion. More recent...

we introduce an implicit method for nding a common element of the set of solutions of systems of equilibrium problems and the set of common xed points of a sequence of nonexpansive mappings and a representation of nonexpansive mappings. then we prove the strong convergence of the proposed implicit schemes to the unique solution of a variational inequality, which is the optimality condition fo...

in this paper, two new cascaded inverters are proposed, by using the series connection of new submultilevel inverters. each of the proposed submultilevel inverters consists of three batteries and eight power switches. four algorithms are presented to determine the voltages of these batteries for each of the proposed structures. in this study the comparison between the proposed structures with c...

according to interactions in multiple grade classes, the present study aims to compare different class compositions in three different groups of fourth-grade multiple grade students in implicit learning and academic achievement. statistical population consists of all fourth grade public elementary school students in piranshahr. 3 groups of students including 8 girls and 8 boys were randomly sel...
