Detecting, modeling and managing relationships between models are central tasks within model-driven engineering. By taking a simple view on software development, we distinguish in a vertical dimension between domain-specific models, core models, and executable models. A typical example for a vertical relationship is the refinement relationship beween a core model and an executable model. In the...

Although horizontal ground forces are only approximately 15% of vertical forces, they account for 47% and 33% of the metabolic cost in walking and running. To explain these disproportionately high metabolic costs, we hypothesized that low horizontal ground forces generate relatively high torques on body segments during locomotion and this is mediated by long moment arms. We compared external fo...

PURPOSE Research has shown that the orientation of the exiting wire from a scleral search coil (nasal in the original coil, inferior in the modified coil) influences the pattern of torsion associated with blinks, presumably due to the upper eyelid touching the wire. The present study was conducted to investigate whether coil wire orientation also influences the pattern of torsion during fixatio...

Introduction: The aim of this paper is to review integration experience in general dentistry curriculum in the world universities in the twenty-first century and advantage of it to review the same curriculum in Iran. Method: In this study, a qualitative method is used. First, by library research and the analysis and interpretation of data, integration of the dental curriculum were some prestig...

Consider a nearest neighbor random walk on the two-dimensional integer lattice, where each vertex is initially labeled either `H' or `V', uniformly and independently. At discrete time step, walker resamples label at its current location (changing to `V' with probability $q$). Then, it takes mean zero horizontal step if new `H', vertical `V'. This model randomized version of deterministic rotor ...

Liquid sloshing is a common phenomenon in the transporting of liquid tanks. Liquid waves lead to fluctuating forces on the tank wall. If these fluctuations are not predicted or controlled, they can lead to large forces and momentum. Baffles can control liquid sloshing fluctuations. One numerical method, widely used to model the liquid sloshing phenomena is Smoothed Particle Hydrodynamics (SPH)....

Most of the Earth's crust contains fluids, and fractures are common throughout the upper part. They exist at a wide range of scales from micro-fractures within grains to major faults and shear zones that traverse the crust. In this paper, the stress-dependent permeability in fractured rock masses have been investigated considering the effects of nonlinear normal deformation and shear dilation o...

Introdouction: The aim of this study was to determine the associations between commonly found pathologic conditions and angulation of the lower third molar teeth. Materials and methods: In this retrospective study, 370 panoramic radiographs consisting of 724 lower third molars were evaluated for any pathologies according to their angulation(mesioangular, distoangular, vertical, or horizontal...
