The pulsed laser welding technique involves complex physical mechanisms, which demand a multiphysics welding simulation for reliable computational analysis. Although the multi-physics simulation provides high accuracy in detailed welding information, it is difficult to apply in practice, as it requires vast computational resources for systematic analysis. We propose a highly efficient and relia...

We present an efficient and accurate grid method for solving the time-dependent Schrodinger equation for an atomic system interacting with an intense laser pulse. Instead of the usual finite difference (FD) method, the radial coordinate is discretized using the discrete variable representation (DVR) constructed from Coulomb wave functions. For an accurate description of the ionization dynamics ...

A three-dimensional numerical model is used to compute the water flow field in a straight flume with a cobble bed. The geometry of the numerical model is a replication of a physical model experiment where the largest cobbles were approximately 10 cm long. Detailed information on the digital terrain model of the bed was available from a laser scan of the bed. In the experiments, flow velocity pr...

background: based on contradictory findings concerning the use of lasers for enamel etching, the purpose of this study was to investigate the shear bond strength of teeth prepared for bonding with er-yag laser etching and compare them with phosphoric acid etching. materials and methods: in this in vitro study forty – eight premolars, extracted for orthodontic purposes were randomly divided in t...

In this paper, we present a Workflow-based grId portal for problem Solving Environment(WISE) which has been developed by integrating workflow, Grid and web technology to provide an enhanced powerful approach for problem solving environment. Workflow technology supports coordinated execution of multiple application tasks on Grid resources by enabling users to describe a workflow by composing man...

We experienced a case of retinopathy of prematurity that was successfully treated with pattern scan laser. Pattern scan laser treatment should be considered as one treatment option for Retinopathy of Prematurity.

In recent years, the emerging theory of grid classes has led to some of the major structural and enumerative developments in the study of permutation patterns. Particular highlights include the characterisation of all possible “small” growth rates (Huczynska and Vatter, 2006; Kaiser and Klazar, 2003; Vatter, 2011) and the subsequent result that all classes with these growth rates have rational ...

Although fuzzy operators have deserved a large attention in the Euclidean case, almost nothing exists concerning the geodesic case. In this paper, we address this question, by de"ning fuzzy geodesic distances between points in a fuzzy set, and geodesic balls in a fuzzy set (based on the comparison of fuzzy numbers), from which we derive fuzzy geodesic mathematical morphology operators. The prop...

This paper provides an explanation for an important institutional feature of staggered time-dependent adjustment rules assumed in a number of macroeconomic models. It identifies strategic complementarity as the crucial factor leading to nonsynchronized decisions in a game-theoretic framework. The paper first shows that nonsynchronization is the equilibrium outcome in an infinite-horizon game in...
