In this paper a novel algorithm for estimating the parametric form of the camera motion is proposed. A novel stochastic vector field model is presented which can handle smooth motion patterns derived from long periods of stable camera movement and also can cope with rapid motion changes and periods where camera remains still. A set of rules for robust and online updating of the model parameters...

In this paper, two different kinds of hoppers were proposed. order to investigate particle behavior in hoppers, the discrete element method (DEM) was introduced and soybeans chosen as test material Particle four samples simulated under flow rate. Results reveal that deflection cone greatly affected behavior. After adding hopper, trajectory can be restrained dust diffusion reduced.different dist...

1. Introduction Diffusion, i.e. the irregular movement of molecules, is quantified by measuring the rate of molecular fluxes in the direction of falling concentration. In contrast to intuition, considering methanol diffusion in a novel type of nanoporous material (MOF ZIF-8) this rate has now been found to be enhanced rather than slowed down by an opposing flux of labelled molecules [1,2]. In t...

The demand for the solutions to different complex numerical optimization problems has long outstripped the ability of engineers to supply them. Since the numerical optimization is a static problem that is naturally similar to the movement of particulates with particle-wave duality in potential field, it can be simulated by the assistance of cooperative searching agents with social information s...

In this paper we present a particle-based method for large scale long time progressive simulation of terrain erosion containing wet granular particles. The wetting process and the propagation through granular material is based on defining the wetness value for each particle representing the amount of water absorbed by granular particles and stored between them, as was originally proposed by Run...

Plant viruses move through plasmodesmata (PD) either as nucleoprotein complexes (NPCs) or as tubule-guided encapsidated particles with the help of movement proteins (MPs). To explore how and why MPs specialize in one mechanism or the other, we tested the exchangeability of MPs encoded by DNA and RNA virus genomes by means of an engineered alfalfa mosaic virus (AMV) system. We show that Caulimov...

We present a quantitative model of word order and movement constraints that enables a simple and uniform treatment of a seemingly heterogeneous collection of linear order phenomena in English, Dutch and German complement constructions (Wh-extraction, clause union, extraposition, verb clustering, particle movement, etc.). Underlying the scheme are central assumptions of the psycholinguistically ...

the gravitational search algorithm (gsa) is a novel optimization methodbased on the law of gravity and mass interactions. it has good ability to search forthe global optimum, but its searching speed is really slow in the last iterations. sothe hybridization of particle swarm optimization (pso) and gsa can resolve theaforementioned problem. in this paper, a modified pso, which the movement ofpar...
