Motion planning in a plane using generalized Voronoi diagrams

Abstract: An algorithm for planning a collision-free path for a rectangle in a planar workspace populated with polygonal obstacles is presented. Heuristic techniques are used to plan the motion along a nominal path obtained from a generalized Voronoi diagram (GVD). The algorithm was demonstrated to be quite fast with execution times comparable to, or exceeding, those of the freeway method. Unlike the freeway method, the GVD technique can be successfully applied to difficult problems which arise in cluttered workspaces. The planned paths stay well away from the obstacles when possible and are somewhat shorter than the freeway paths due to parabolic arcs around corners. Furthermore, motion along the paths is smooth in the sense that rotations are performed during translation, not just at isolated points in the workspace. >

New Product Quality and Product Development Teams

Abstract: New product quality has been found to have a major influence on the market success and profitability of a new product. Firms are increasingly using cross-functional teams for product development in hopes of improving product quality, yet researchers know little about how such teams affect quality. The author proposes and tests a series of hypotheses regarding how new product quality is affected by team characteristics (functional diversity and information integration) and contextual influences (time pressure, product innovativeness from the firm’s perspective, customers’ influence on the product development process, and quality orientation in the firm). The findings reveal that quality is positively related to information integration in the team, customers’ influence on the product development process, and quality orientation in the firm. New product quality is negatively influenced by the innovativeness of the new product from the firm’s perspective. However, information integration mitigates th...

Atmospheric aerosol over Vermont: chemical composition and sources.

Abstract: Aerosol chemical composition data for PM2.5 samples collected during the period from 1988 to 1995 at Underhill, VT, were analyzed. Sulfur and black carbon mass concentrations ranged from 0.01 to 6.5 μg m-3 and from 0.05 to 2.2 μg m-3, respectively, while the total fine aerosol mass concentration ranged from 0.2 to 51.1 μg m-3. Seasonal variations with maxima during the summer and minima in winter/spring were observed for sulfur and the fine mass concentrations. No annual pattern was observed for black carbon. Seasonal variations for most of the other anthropogenic species had maxima in winter and spring and minima in the summer. A factor analysis method, positive matrix factorization (PMF), utilizing error estimates of the data to provide optimum data point scaling was used to obtain information about possible sources of the aerosol. An 11-factor solution was obtained. The six sources representing wood burning, coal and oil combustion, coal combustion emissions plus photochemical sulfate production, metal...

Chemical Self-assembly for Electronic Applications

Abstract: The current state of spontaneous formation of self-assembled monolayers (SAMs) on different substrates as well as on nanoparticles (referred to as monolayer-protected clusters, MPCs) is surveyed. Attention is then focused onto the assembly and self-assembly of nanoparticles (including MPCs), polymers, and polyelectrolytes into two-dimensional (2D) arrays and three-dimensional (3D) networks. Examples are given for the potential electronic applications of SAMs, MPCs, and the 2D and 3D structures fabricated from them and from polymers and polyelectrolytes. These examples include the formation of junctions, heterojunctions, and single-electron-transfer devices.
