Details of parallel-sparse Domain Decomposition (DD) with multi-point constraints (MPC) formulation are explained. Major computational components of the DD formulation are identified. Critical roles of parallel (direct) sparse and iterative solvers with MPC are discussed within t
Recognizing Retro-Reflectors with an Obliquely-Oriented Multi-Point Sonar and Acoustic Flow
This paper applies acoustic principles and a novel scanning method motivated by acoustic flow to recognize retro-reflectors directly from sonar echoes while performing drive-by scanning. Right-angle corners and cylinders form specular retro-reflectors that produce strong echoes w
Order Barriers for Symplectic Multi-value Methods
We study the question whether multistep methods or general multi-value methods can be symplectic. Already a precise understanding of symplecticity of such methods is a nontrivial task, because they advance the numerical solution in a higher dimensional space (in contrast to one-s
Reference Point Methods in Vector Optimization and Decision Support
This paper presents a summary of reference point methodology in vector optimization and decision support. The methodology was developed at IIASA since 1980 and applied in numerous projects, both in IIASA and elsewhere. The paper presents methodological foundations, basic concepts
Convergence of Multi-point Flux Approximations on General Grids and Media
The analysis of the Multi Point Flux Approximation (MPFA) method has so far relied on the possibility of seeing it as a mixed finite element method for which the convergence is then established. This type of analysis has been successfully applied to triangles and quadrilaterals,
Convergence of Multi Point Flux Approximations on Quadrilateral Grids
This paper presents a convergence analysis of the multi point flux approximation control volume method, MPFA, in two space dimensions. The MPFA version discussed here is the so–called O–method on general quadrilateral grids. The discretization is based on local mappings onto a re
Link adaptation for energy-efficient uplink coordinated multi-point receptions
We investigate link adaptation methods for energy-efficient uplink coordinated multi-point receptions. A system model for practical cellular networks is introduced, in which only a subset of base stations participates in cooperative link adaptation and cooperative decoding for up
Multi-Point Special Boundary-Value Problems and Applications to Fluid Flow Through Porous Media
In this paper we propose a numerical scheme based on finite differences for the numerical solution of nonlinear multi-point boundary value problems over adjacent domains. In each subdomain the solution is governed by different equation. The solutions are required to be smooth acr
Experimental Study on Battery-Less Sensor Network Activated by Multi-Point Wireless Energy Transmission
Wireless Sensor Networks (WSNs) employ numerous sensors deployed in target environments to gather sensing data via wireless links. In the conventional WSNs, installation placement of sensor nodes operated by electrical plug are restricted by limited placements of the plugs. Emplo
Multi-Point Contact Models for Dynamic Self-Righting of a Hexapod
In this paper, we report on the design of a model-based controller that can achieve dynamical self-righting of a hexapod robot. Extending on our earlier work in this domain, we introduce a tractable multi-point contact model with Coulomb friction. We contrast the singularities in
