In natural language processing up to now mainly rule-based systems have been used. The rulebased approach has been successful for limited domains, where the manual construction of the rules is feasible. In recent studies, however, a need for automatic generation of the rules has been seen. On the other hand, when children learn their mother tongue no explicit rules seem to be needed. Therefore,...

We develop a multiscale Eulerian–Lagrangian localized adjoint method for transient linear advection– diffusion equations with oscillatory coefficients, which arise in mathematical models for describing flow and transport through heterogeneous porous media, composite material design, and other applications.

Landslides are one of the main natural threats for both people and infrastructure in mountainousregions. In most cases, landslides are triggered by the loss of cohesion in a soil due to the increasingwater saturation level after long or intense rainfalls. Only little is known on the triggering of failuresat the microscopic scale due to the limited experimental accessibility and ...

The chemicals used for the NPs synthesis are TetraEthylOrthoSilicate (TEOS), l-Arginine, chloride acid 0.1M and ethanol. They were supplied by Aldrich and used as received. High-purity deionized water (18.2 M.cm) was produced using Millipore Milli-Q Gradient system. The synthesis follows the same protocol as in our previous work [1]. It is performed in a 2000 ml reactor thermostated with hot wa...

A data model for library material usage in city libraries is proposed. The data model was designed with the aim of supporting all evidenced information requirements for the library material usage. The proposed data model is used in the development of the fourth version of the BISIS library software system. AMS Mathematics Subject Classification (2000): 68U35

We study experimentally the fracture mechanisms of a model cohesive granular medium consisting of glass beads held together by solidified polymer bridges. The elastic response of this material can be controlled by changing the cross-linking of the polymer phase, for example. Here we show that its fracture toughness can be tuned over an order of magnitude by adjusting the stiffness and size of t...
