Mathematical models in the form of differential equations can often not be solved analytically, but need to be simulated by means of a numerical method. Particle methods are mesh-free schemes that use independent or pairwise interacting particles to represent the physical properties of a system. This allows for natural adaptivity in complex or deforming geometries. The Lagrangian frame of refer...

let be a locally compact non?abelian group and be a compact subgroup of also let be a ?invariant measure on the homogeneous space . in this article, we extend the linear operator as a bounded surjective linear operator for all ?spaces with . as an application of this extension, we show that each frame for determines a frame for and each frame for arises from a frame in via the linear operator .

Inertial effects can affect several properties of physical systems. In particular, in the context quantum mechanics, such has been studied diverse contexts. this paper, starting from Schrödinger equation for a rotating frame, we propose toy model to describe influence noninertial on one-dimensional ring presence uniform magnetic field. We first study how electronic states are affected by rotati...

Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

the combination of flexural frame and shear wall is one of the suitable systems to apply in reinforced concrete buildings. the deflections of flexural frame become limited due to the high stiffness of wall and the interaction of these systems. tall buildings even higher than fifty stories can be designed by using frame- wall systems. with respect to special behavior of flexural frame or shear w...

We present an algorithm for interactive display of trimmed NURBS surfaces. The algorithm converts the NURBS surfaces to B ezier surfaces and NURBS trimming curves into B ezier curves. It tessellates each trimmed B ezier surface into triangles and renders them using the triangle rendering capabilities common in current graphics systems. It makes use of tight bounds for uniform tessel-lation of B...

In multimedia communications, different characteristics of wireless channel error models lead to different effects on the delivered video quality level. In this paper, we analyze the effects of wireless channel errors on the quality of MPEG video stream. First, we use an analytical model to derive an application-level evaluation metric, the Decodable Frame Rate (Q). This is more sufficient for ...

The present paper focuses on the Lagrange mechanics-based description of small oscillations of a spherical pendulum with a uniformly rotating suspension center. The analytical solution of the natural frequencies' problem has been derived for the case of uniform rotation of a crane boom. The payload paths have been found in the inertial reference frame fixed on earth and in the noninertial refer...

We describe a nonscanning, fiber bundle endomicroscope that performs optically sectioned fluorescence imaging with fast frame rates and real-time processing. Our sectioning technique is based on HiLo imaging, wherein two widefield images are acquired under uniform and structured illumination and numerically processed to reject out-of-focus background. This work is an improvement upon an earlier...
