I describe how SBDS can be utilised to break the symmetry in the Peaceably Coexisting Armies of Queens problem. Including how SBDS can be combined with other CSP techniques to produce improved performance.
In this paper, a number of symmetry-breaking (SB) constraints are considered to improve the performance and decrease computational effort needed in the solution of Process Plant Layout (PPL) Problems. The PPL problems are formulated as mixed-integer linear (MILP) models. In order to determine the efficiency of the symmetry-breaking formulations, test runs are carried out on three different prob...
For spontaneous breaking of global or gauge symmetry, it is superfluous to assume that the vacuum expectation value of the scalar field manifesting the symmetry is nonvanishing. The vacuum with spontaneous symmetry breaking simply corresponds to the nonzero number of particles of one or more components of the real scalar field.
Breaking bad news is an unavoidable part of the medical profession, and doctors and patients stand at the two sides of this function. There are different views about how to break bad news in different cultures and societies. In this study we assessed the viewpoints of hospitalized patients on how to break bad news. This cross sectional study was performed in 2011 at the Jahrom University of Me...
In this article, a numerical meshless method called Weakly Compressible Smoothed Particle Hydrodynamic (WCSPH) is used to simulate the solitary wave breaking process on the beach. The present model is a two dimensional model that considers the fluid weakly compressibility. This model solves the viscous fluid equations to obtain velocity field and density and solves the equation of state to obta...
In order to investigate different treatment effects on germination in Gundelia tournefortii, three factorial experiments were carried out in the completely randomized design with three replications. The first factor was stratification at 4oC in three levels including 0, 3 and 6 weeks, the second factor was mechanical scarification in two levels including seeds with/without scarification and the...
An in vitro study on the role of intracellular calcium ions in healing of excisional wound in rabbit was undertaken. We employed two drugs namely, glibenclamide and nitroglycerin that are topically applied in vivo to modulate the activity of intracellular calcium. Our model consisted of a 15 ´ 15 mm excisional wound. Seven groups of New Zealand rabbits were used. The first three groups served a...
The propagation of secondary surges can lead to unexpected interaction events with navigation ships and downstream hydraulic structures; hence, they may cause accidents structural damage. In the present study, physical experiments were performed in a long water wave tank study evolution breaking undular advancing still water. Both free-surface velocity measurements conducted. It was observed th...
We calculate the exact tree-level scalar mass matrices resulting from symmetry breaking using the most general gauge-invariant scalar potential of the 331 model, both with and without the condition that lepton number is conserved. Physical masses are also obtained in some cases, as well as couplings to standard and exotic gauge bosons.
