Motivation The motivation for Rectangular Partitioning comes from my work. The application I help create has forms that can be designed by third parties, and it also has a layout engine that makes it easy to change the layout of a form based on the size of the form and its contents. The layout engine takes as it’s input a table of cells and their contents, along with attributes specifying how a...

a. Witness Professor Reyntjens (PW77) asked permission to address the Chamber. First, he advised the Chamber that he had made an error in an answer he had given yesterday and offered further explanations. Second, he advised the Chamber that he had been given documents yesterday by Counsel for Bagosora (Mr. Constant), some of which were stamped “confidential” and which he recognized as being doc...

In this paper, a novel hybrid FEM and Peridynamic modeling approach proposed in Ni et al. (2020) is used to predict the dynamic solution of hydro-mechanical coupled problems. A modified staggered algorithm adopted solve system. one-dimensional consolidation problem solved first validate approach, both δ-convergence mr-convergence studies are carried out determine appropriate discretization para...

This work considers the confining and scattering phenomena of electrons in a Lieb lattice subjected to influence rectangular electrostatic barrier. In this setup, hopping amplitudes between nearest neighbors orthogonal directions are considered different, next-nearest neighbor interaction describes spin-orbit coupling. makes it possible confine generate bound states, exact number which is exact...

Recently pianokey weirs become important in hydraulic structures. In this paper effect of the number of cycles on the flow of pianokey sideweir has been investigated experimentally. 45 experiments on single, two, four, six cycles pianokey and sharp crest linear weir on different heads (H/P = 0.3, 0.5, 0.65, 0.85 and 1) has been conducted. The input flow rate to the main channel was applied in s...

an efficient and simple method for the preparation of si-imidazole-hso4 functionalized magnetic fe3o4 nanoparticles (si-im-hso4 mnps) and used as an efficient and reusable magnetic catalysts for the regioselective ring opening of epoxides under green conditions in water. this catalyst was used for the ring opening of epoxide corresponding to the thiocyanohydrins and azidohydrines. compared to t...

We report here several particle membrane filters (8 × 8 mm) with circular, hexagonal and rectangular through holes. By varying hole dimensions from 6 to 12 μm, opening factors from 4 to 45 % are achieved. In order to improve the filter robustness, a composite silicon nitride/Parylene membrane technology is developed. More importantly, fluid dynamic performance of the filters is also studied by ...

In this paper, a class of extended lower and upper levelings is investigated. Here, some conditions are imposed to the criteria for building extended lower and upper levelings in order to generate openings and closings with reconstruction criteria. The idea of building these new openings and closings comes from the notions of morphological filters by reconstruction and levelings. The main goal ...

This paper analyzes the impact of international trade on the quality of institutions, such as contract enforcement, property rights, or investor protection. It presents a model in which institutional differences play two roles: they create rents for some parties within the economy, and they are a source of comparative advantage in trade. Institutional quality is determined as an equilibrium of ...
