Impact of Lump Sum Expense Rates on Public Revenue

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015
Lump sum expense has special role within the Czech tax system. As the percentages of the lump sum expense used in the Czech Republic are high compared to other EU countries, they are often criticized as distortive and government searches for ways to ...

A Study on Lump and Interaction Solutions to a (3 + 1)-Dimensional Soliton Equation

open access: yesComplexity, 2019
Based on bilinear formulation of a (3 + 1)-dimensional soliton equation, lump solution and related interaction solutions are investigated. The lump solutions of the soliton equation are classified into three cases with nonsingularity conditions being ...

Observation of Lump Solitons

open access: yesPhysical Review Letters
Solitons are the cornerstone of nonlinear physics. The integrability of nonlinear equations is the basis of this universal concept. However, most multidimensional systems lack integrability, a fundamental limitation that challenges the existence of solitons in high dimensions. A remarkable exception would be the lump soliton, a two-

PENGARUH KADAR LUMPUR PADA AGREGAT HALUS DALAM MUTU BETON

open access: yesTeknik, 2012
Clay lumps on the aggregate levels is one of the factors that may cause disruption of the binding process andhardening of concrete. Clay lump can not blend with cement so that blocking a merger between the cement withaggregates which eventually led to ...

Design of lump coal transshipping anti-fracturing system based on PLC

open access: yesGong-kuang zidonghua, 2016
For a problem that lump coal fractures easily because of large drop of transshipping point during lump coal transport in coal preparation plant, a lump coal transshipping anti-fracturing system based on PLC was proposed.
