Abstract. In Sussman, Smereka, and Osher [J. Comp. Phys., 94 (1994), pp. 146–159], a numerical scheme was presented for computing incompressible air–water flows using the level set method. Crucial to the above method was a new iteration method for maintaining the level set function as the signed distance from the zero level set. In this paper we implement a “constraint” along with higher order ...

In this paper we develop results based on geometric mechanics to study the controllability of a class of controlled under-actuated left invariant mechanical systems on Lie groups. We exploit the invariance of the controlled nonlinear dynamics to the group action (symmetry) to derive a set of reduced dynamics for the system. We 3rst present su4cient conditions for the controllability of the redu...

W designing supply chains, firms are often faced with the competing demands of improved customer service and reduced cost. We extend a cost-based location-inventory model (Shen et al. 2003) to include a customer service element and develop practical methods for quick and meaningful evaluation of cost/service trade-offs. Service is measured by the fraction of all demands that are located within ...

Finland’s community pharmacy system provides an example of a privately-owned regulated being proactively developed by the profession and its stakeholders. Community pharmacists have legal duty to promote safe rational medicine use in outpatient care. The development professionally oriented practice has been nationally coordinated since 1990s with support national steering group consisting profe...

Introduction Laser is being used in apparel industry from ninenteenth century. Recently the use of laser in apparel industry is increasing in cutting garment patterns, patterning designer neckties, 3D body scanning, denim fading and engraving leather (Nayak and Khandual 2010; Istook and Hwang 2001; Simmons and Istook 2003; Ortiz-Morales et al. 2003; Ozguney 2007; Bahtiyari 2011). The major reas...

This article describes a class of reconfigurable computing system called online architectures. These architectures use an online algorithm to make run-time reconfiguration decisions that continually adapt the underlying architecture to match the application’s current computational demand. Online architectures have several potential advantages, including better resource utilization (reduced cost...

We present an automated system for detecting visual changes on tunnel linings. By registering new images to a three-dimensional tunnel surface model, recovered using Structure and Motion techniques, we are able to detect and localise changes accurately in order to assist visual inspection by a human expert. We formulate the problem of detecting changes probabilistically and exploit different fe...

We study the dissipative quantum dynamics and the asymptotic behavior of a particle in a bistable potential interacting with a sub-Ohmic broadband environment. The reduced dynamics, in the intermediate to strong dissipation regime, is obtained beyond the two-level system approximation by using a real-time path integral approach. We find a crossover dynamic regime with damped intra-well oscillat...
