The implicit convex feasibility problem attempts to find a point in the intersection of a finite family of convex sets, some of which are not explicitly determined but may vary. We develop simultaneous and sequential projection methods capable of handling such problems and demonstrate their applicability to image denoising in a specific medical imaging situation. By allowing the variable sets t...

It is often held that although explicit learning declines in the course of normal aging, implicit learning is relatively preserved. Here we summarize research from our group which leads us to argue that some forms of implicit learning do decline with adult age. In particular, we propose that there are age-related declines in implicit learning of probabilistic sequential relationships that occur...

The serial reaction time (SRT) task was used to compare learning of a complex sequence by action (participants responded to sequential stimuli), by observation (participants watched but did not respond to sequential stimuli), and by action-observation (participants watched an expert model responding to sequential stimuli). Each of these groups was compared with an untrained control group. Exper...

Diffusion model is increasingly employed to simulate diffusion of biological compounds including nutrient, oxygen and chemoattractants in the agent-based model (ABM). However, it takes long compute time to employ conventional numerical methods such as alternating direction implicit (ADI) method to approximate the exact solution of the diffusion processed by sequential computing algorithm. To ov...

In this paper, we consider a reduced computational model of methane hydrate formation in variable salinity conditions, and give details on the discretization and phase equilibria implementation. We describe three time-stepping variants: Implicit, Semi-implicit, and Sequential, and we compare the accuracy and efficiency of these variants depending on the spatial and temporal discretization param...

Test pattern storage is an important problem aaect-ing all Design for Testability (DfT) techniques based on scan-path. Built-In Self Test (BIST) methodologies are used in conjunction to scan-path techniques for reducing the amount of test patterns that must be stored. This paper analyzes two SCAN/BIST approaches and identiies conditions which guarantee that such techniques require shorter test ...

we introduce an implicit method for nding a common element of the set of solutions of systems of equilibrium problems and the set of common xed points of a sequence of nonexpansive mappings and a representation of nonexpansive mappings. then we prove the strong convergence of the proposed implicit schemes to the unique solution of a variational inequality, which is the optimality condition fo...

This paper introduces an approach to level-set topology optimization that can handle multiple constraints and simultaneously optimize non-level-set design variables. The key features of the new method are discretized boundary integrals to estimate function changes and the formulation of an optimization sub-problem to attain the velocity function. The sub-problem is solved using sequential linea...

Networked unix workstations as well as workstations running Windows 95 or Windows NT are fast becoming the standard computing environments at many universities and research sites. Researchers and educators seek simple methods to harness the potential for parallelism implicit in these computing networks. This paper investigates the ease and efficiency of Java sockets, Java remote method invocati...
