We present a method for a structural simulation of destructible 3-dimensional metal frame buildings at interactive frame rates. Beams, floor slabs, and wall sections are simulated as rigid bodies and joined together by rigid constraints. Each constraint is given a set of breaking thresholds for the force and torque around each axis, allowing them to fail if the structure is overloaded or damage...

Aquatic vegetation in rivers often modifies hydraulic resistance and can enhance seasonally occurring flooding. To which extent a plant constitutes an obstacle in the flow is strongly influenced by its biomechanical traits which determine the ability of plants to reconfigure in the flow, i.e. to adopt a shape that minimizes drag forces and hence to smooth the flow dynamics in and around submerg...

Abstract: We propose a spontaneous A4 flavour symmetry breaking scheme to understand the observed pattern of quark and neutrino mixing. The fermion mass eigenvalues are arbitrary, but the mixing angles are constrained in such a way that the overall patterns are explained while also leaving sufficient freedom to fit the detailed features of the observed values, including CP-violating phases. The...

A unified treatment of the cohesive and conducting properties of metallic nanostructures in terms of the electronic scattering matrix is developed. A simple picture of metallic nanocohesion in which conductance channels act as delocalized chemical bonds is derived in the jellium approximation. Universal force oscillations of order ́FylF are predicted when a metallic quantum wire is stretched to ...

A self-consistent particle-phonon coupling model is used to investigate the properties of the isobaric analog resonance in 208Bi. It is shown that quantitative agreement with experimental data for the energy and the width can be obtained if the effects of isospin-breaking nuclear forces are included, in addition to the Coulomb force effects. A connection between microscopic model predictions an...

Abstract For a drill bit, the cutter is most important part to break rock. In oilwell drilling, polycrystalline diamond compact (PDC) bit widely used shear rock formation. this paper, finite element model with including axe-shaped PDC and formation developed study breaking behaviours. Results show that effect of on better than planar cutter. The front rake angle face angel play significant role...

Forces between fully hydroxalated silica surfaces were measured using an atomic force microscope. The measurements were conducted in Nanopure water and in solutions containing various organic solutes such as methanol, ethanol, trifluoroethanol (TFE), and pyridine. The results obtained in Nanopure water showed a strong short-range repulsive force at distances below 15 nm. This non-DLVO force can...

The objective of this study was to determine the influence housing system on physical, morphological, and mechanical properties Japanese quail (Coturnix coturnix japonica) eggs. A total 240 eggs were collected from quails kept in two different systems: cage aviary (120 each system). Eggs significantly (P<0.05) heavier than (11.85 g vs. 10.93 g), also longer, wider had larger geometric mean diam...

Wave height as well as water depth at the breaking point are two basic parameters which are necessary for studying coastal processes. In this study, the application of soft computing-based methods such as artificial neural network (ANN), fuzzy inference system (FIS), adaptive neuro fuzzy inference system (ANFIS) and semi-empirical models for prediction of these parameters are investigated. Th...
