This paper presents a novel computational framework based on dynamic spherical volumetric simplex splines for simulation of genuszero real-world objects. In this framework, we first develop an accurate and efficient algorithm to reconstruct the high-fidelity digital model of a real-world object with spherical volumetric simplex splines which can represent with accuracy geometric, material, and ...

exchange rate prediction, as one of the main variables in macroeconomics, has been one of the aims of the economic research for a long time. for modeling and predicting exchange rate we apply stochastic differential equation, specifically we use geometric brownian motion (gbm) and jump-diffusion process (mjdp) attributed to merton. we show that the result of simulation based on gbm and mjdp out...

In the permanent magnet linear synchronous motor (PMLSM), force ripple is harmful, useless and disturbing. The force ripple is basically composed of two components: detent force and mutual force ripple. This force is influenced by the geometric parameters of the permanent magnet (PM) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stato...

Finding new families of distributions has become a popular tool in statistical research. In this article, we introduce a new flexible four-parameter discrete model based on the Marshall-Olkin approach, namely, the discrete Kumaraswamy Marshall-Olkin exponential distribution. The proposed distribution can be viewed as another generalization of the geometric distribution and enfolds some importan...

Performing fast and accurate collision detection between geometric models is still most open problems in modeling, robotics, manufacturing and computer-simulated environments. Most of previous method seems to have their own specification and restricted to a specific geometric models. For example, convex polytopes tend to solve accuracy problems but left behind the speed of collision detection. ...

In this paper a new model for communication in MANETs will be presented: Instead of omnidirectional transmissions, as assumed in most papers and all existing systems, the members are allowed to submit data in a fixed number of different directions (sector subdivision) and to adjust the transmission power in each sector separately. A simulation environment (Simulation Environment for Ad Hoc Netw...

Acoustic design is a difficult problem, because the human perception of sound depends on such things as decibel level, direction of propagation, and attenuation over time, none of which are tangible or visible. The advent of computer simulation and visualization techniques for acoustic design and analysis has yielded a variety of approaches for modeling acoustic performance. However, current co...

The objective of this paper is to present an Automated Geometric defect Diagnosis methodology for EEPROM cell (AGDE). This method focuses on speeding up the diagnosis process of geometric defect. It is based on a mathematical model generated with a “Design Of Simulation” (DOS) technique. The DOS technique takes as input, simulations results of a floating gate transistor with different given geo...

Conventional holonomic or nonholonomic constraints are defined as geometric constraints in this paper. If the total energy of a dynamic system can be computed from the initial energy plus the time integral of the energy input rate due to external or internal forces, then the total energy can be artificially treated as a constraint. The violation of the total energy constraint due to numerical e...

We develop a tractable model for elucidating the assembly pathways by which an icosahedral viral shell forms from 60 identical constituent protein monomers. This poorly understood process a remarkable example of macromolecular self-assembly occuring in nature and possesses many features that are desirable while engineering self-assembly at the nanoscale. The model uses static geometric constrai...
