A linear complementarity problem with an n by 2n “P”-matrix
1978The problem considered in this paper is given by the conditions: w=q+Mv+Nx, w≧0, v≧0, x≧0, v≦r, w T v=0 and (r−v) T x=0. Here q, r are n-vectors with r>0 and M, N are n by n matrices. We say that an n by 2n matrix (M, N) has the P-property if all of its “principal” minors are positive.

Development of Fe-P Matrix Composites Containing Embedded Solid Lubricants
Materials Science Forum, 2014In this work the processing of composites containing graphite or hexagonal boron nitride dispersed in a ferrous matrix alloyed with phosphorous was addressed, with the goal of developing self-lubricating sintered materials with high mechanical resistance. Phosphorous is an alloy element characteristic in powder metallurgy for promoting the formation of

Extended p-matrix model to calculate imbalance characteristics of CRF filters
IEEE Ultrasonics Symposium, 2004, 2005An extended P-matrix model is introduced that includes additional electrical ports to take into account particular electrode polarities. The transduction efficiency and static capacitance of any particular electrode are calculated using the model of reflecting grating and electrostatic charge distribution in the total electrode structure.

Off-shell two-particle scattering amplitude in the P-matrix approach
Theoretical and Mathematical Physics, 1988A generalization of the P-matrix approach which makes it possible to describe the interaction of two particles off the energy shell is proposed. Explicit separation in the wave function of a part corresponding to free motion yields a compact expression for the off-shell scattering amplitude and gives directly a method for separable expansion of the ...

Study on a novel SAW sensor in TPMS based on the P-matrix model
2008 3rd IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2008Tire pressure monitoring system (TPMS) is an electronic system monitoring the air pressure in a pneumatic tire at real time. The goal of this paper is to analyze and optimize the design of a novel wireless passive SAW sensor used in TPMS, via theoretical derivation and simulations.

A nonlinear P matrix model to simulate intermodulation products in SAW devices
2012 IEEE International Ultrasonics Symposium, 2012Nonlinear intermodulation distortion inside duplexers is a limitation for the sensitivity of mobile devices receivers. A perturbation approach for non linear harmonic acoustic generation along the propagation of surface acoustic wave is derived. It is used to extend the P matrix model to non linear generation of harmonics and mixing products. Interface

A Simple P-Matrix Linear Complementarity Problem for Discounted Games
2008The values of a two-player zero-sum binary discounted game are characterized by a P-matrix linear complementarity problem (LCP). Simple formulas are given to describe the data of the LCP in terms of the game graph, discount factor, and rewards. Hence it is shown that the unique sink orientation (USO) associated with this LCP coincides with the strategy

Fast calculation of the gradient and the difference vector of IDT's p matrix [PDF]
IEEE Ultrasonics Symposium, 2004, 2005 The transduction. and reflection coefficients of SPUDTs are usually determined by optimization methods. Some methods need gradients or the difference vectors of IDT's P matrix in order to calculate the corresponding quantities of the error function.

Simple Stochastic Games and P-Matrix Generalized Linear Complementarity Problems
2005We show that the problem of finding optimal strategies for both players in a simple stochastic game reduces to the generalized linear complementarity problem (GLCP) with a P-matrix, a well-studied problem whose hardness would imply NP = co–NP. This makes the rich GLCP theory and numerous existing algorithms available for simple stochastic games.
