We present three competing predictions of the organizational gender diversityperformance relationship: a positive linear prediction, a negative linear prediction, and an inverted U-shaped curvilinear prediction. The paper also proposes a moderating effect of industry type (services vs. manufacturing). The predictions were tested using archival quantitative data with a longitudinal design. The r...

A high order accurate discontinuous galerkin method based curvedelement implementation in OpenFOAM is presented in this work. The degree of freedom points on origin straight side mesh are mapped to curvilinear edges by finding nearest points on boundary. Then the deformation are transported to the inner points by blended method. Based on the run-time dynamic code of OpenFOAM, we design a conven...

Mesh generation is a useful tool for obtaining discrete descriptors of biological objects represented by images. The generation of meshes with straight sided elements has been fairly well understood. However, in order to match curved shapes that are ubiquitous in nature, meshes with high-order elements are required. Moreover, for the processing of large data sets, automatic meshing procedures a...

We give a partial “quasi-stratification” of the secant varieties of the order d Veronese variety Xm,d of P. It covers the set σt(Xm,d) † of all points lying on the linear span of curvilinear subschemes of Xm,d, but two “quasi-strata” may overlap. For low border rank two different “quasi-strata” are disjoint and we compute the symmetric rank of their elements. Our tool is the Hilbert schemes of ...

We discuss the generation of curvilinear composite overlapping grids and the numerical solution of partial differential equations on them. A composite overlapping grid consists of a set of curvilinear component grids that cover a region and overlap where they meet. Continuity conditions (interpolation) are imposed at the overlapping boundaries. The principal advantage of composite grids is in t...

This paper describes the design, fabrication and characterization of Polyvinylidene Fluoride (PVDF) based piezoelectric energy harvester that scavenges energy from the movement of human limbs. It investigates the effect of a piezolaminated curvilinear shell structure on the power density of a wearable energy harvester through Finite Element Method (FEM) and experimental results. Curvilinear She...

A large portion of image contours is characterized by local properties such as sharp variations of the image intensity across the contour. The integration of local image descriptors estimated by using these local properties into curvilinear descriptors is a difficult problem from a theoretical viewpoint because of the combinatorially large number of possible curvilinear descriptors. To deal wit...

Abstract Health monitoring of structures and people requires the integration sensors devices on various 3D curvilinear, hierarchically structured, even dynamically changing surfaces. Therefore, it is highly desirable to explore conformal manufacturing techniques fabricate integrate soft deformable complex curvilinear Although planar fabrication methods are not directly suitable manufacture surf...

This paper addresses the problem of updating a rough, odometric estimate of the pose of mobile robot, by means of a single range measure. The linearization errors, typical in curvilinear environments, often make the Extended Kalman (EK) estimate unreliable. Therefore, a second-order method is proposed, in which the measurement result is approximated in terms of a two-degree function of the pose...

Satellite imagery provides an effective aid to city planning. From a high-resolution spatial image, useful information such as road networks may be extracted readily. In this work we study a method to automate the extraction of curvilinear objects such as roads and canals from the very-high resolution multi-spectral IKONOS satellite imageries. Curvilinear feature extraction is composed of two s...
