Evolution of initial discontinuities in the Riemann problem for the Kaup-Boussinesq equation with positive dispersion. [PDF]
We consider the space-time evolution of initial discontinuities of depth and flow velocity for an integrable version of the shallow water Boussinesq system introduced by Kaup.

No more walls! A tale of modularity, symmetry, and wall crossing for 1/4 BPS dyons [PDF]
We determine the generating functions of 1/4 BPS dyons in a class of 4d N $$ \mathcal{N} $$ = 4 string vacua arising as CHL orbifolds of K3 × T 2, a classification of which has been recently completed. We show that all such generating functions obey some

The automated inspection of weld beads is of great importance for many industrial processes. Failures may cause a loss of mechanical resistance of the weld bead and compromise the manufactured part. Several methods have been proposed in the literature to

Geological structures and discontinuities in the rock are weak areas and groundwater infiltration pathways. The existence of geological structures and discontinuities will reduce the level of rock shear strength and the main implication is to increase ...

Learning non-stationary and discontinuous functions using clustering, classification and Gaussian process modelling [PDF]
Surrogate models have shown to be an extremely efficient aid in solving engineering problems that require repeated evaluations of an expensive computational model. They are built by sparsely evaluating the costly original model and have provided a way to

TRENDS IN THE DEVELOPMENT OF DETONATION ENGINES FOR HIGH-SPEED AEROSPACE AIRCRAFTS AND THE PROBLEM OF TRIPLE CONFIGURATIONS OF SHOCK WAVES. Part II - Research of counterpropagating shock waves and triple shock wave configurations [PDF]
The paper deals with current issues of the interference theory development of gas-dynamic discontinuities as applied to a problem of propulsion refinement for the air-spacecrafts, designed for hypersonic flight speeds.

Geo-Engineering Analysis and Evaluation of Unstable Rocky Slopes near Shaqlawa, NE Iraq
Engineering Geological study of rock slope stability was conducted in two stations along the Shaqlawa region route. Rock slopes and discontinuities were thoroughly investigated at each site, and the linkages between failures were identified. The

Humiria balsamifera is an infraspecific complex of high phenotypic variation and widely distributed in northern South America. Leaf traits are traditionally considered the most relevant taxonomic characters for varietal level delimitation in the group ...
