In this paper, we compare how two different types of political regimes—direct versus representative democracy—redistribute income towards the relatively poor segments of society after the introduction of universal and equal suffrage. Swedish local governments are used as a testing ground since this setting offers a number of attractive features for a credible impact evaluation. Most importantly...

At 1 AU there is a distinct boundary (the stream interface) at the leading edge of a stream in the solar wind, characterized by an abrupt drop in density, a similar increase in temperature and a small increase in speed. In some cases this is a tangential discontinuity; in others it is probably evolving into a tangential discontinuity. It is suggested that stream interfaces form in the interplan...

In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...

The quest for the ideal flow visualization reveals two major challenges: interactivity and accuracy. Interactivity stands for explorative capabilities and real-time control. Accuracy is a prerequisite for every professional visualization in order to provide a reliable base for analysis of a data set. Geometric flow visualization has a long tradition and comes in very different flavors. Among th...

We present a method for image-based visualization of flow fields on unstructured grids. For interactive exploration of flow data from CFD simulations, we combine GPU-accelerated surface extraction methods and line integral convolution (LIC) in a multi-pass algorithm. In contrast to other highly efficient methods, computation of stream lines is performed directly on the unstructured grid, where ...

As the demand for electricity continues to grow, coverage of transmission lines is getting larger. Despite continuous improvement grid system, are still vulnerable various natural disasters. At same time, many installed in areas with harsh environments and other places that difficult operation maintenance personnel reach, which brings huge challenges lines. Therefore, how effectively detect sta...

We present a novel algorithm for the geometric extraction of stream volume segmentation for visualization of grid-less flow simulation. Our goal is the segmentation of different paths through a mixing tube where the flow is represented by scattered point sets approximated with moving least squares. The key challenges are the watertight construction of boundary representations from separatrices....

In this paper, we have used a control volume method to investigate the problem of a fully coupled fluid flow with heat transfer in a rectangular domain with slip wall boundary conditions. We have used this method to solve the governing equations and thereby to compute the convective and diffusive fluxes at the cell faces of the control volumes considered around the grid points of computational ...

The treatment of stream lines path lines and streak lines is a powerful method for visualizing the behavior of unsteady i e time dependent ow elds Although a closed parametric form of these lines does not exist we show how to compute their curvatures The visualiza tion of the curvatures of these curves shows several aspects of the ow such as location and movement of turbulent areas The techniqu...
