This paper describes a few mild design constraints which permit rapid adaptation of modeling code for linear wave propagation to imaging/inversion or design optimization applications, retaining parallelism and other performance enhancements of the underlying simulator. It also describes an abstract software framework preserving the modularity of both optimization and modeling software in buildi...

Novel biosensors, based on immobilized creatininase, creatinase and urease are developed, using ISFETs with weak inversion at pH 6-8 and 37.0C. The ISFETs with circuitry, demonstrate a linear relationship of urea and creatinine at the range of 0-200 mM and 0-20 mM, respectively. Preliminary results show that biosensors operating in weak inversion mode can eliminate many of the disadvantages of ...

We derive a branch-and-bound algorithm to find an optimal inversion median of three signed permutations. The algorithm prunes to manageable size an extremely large search tree using simple geometric properties of the problem and a newly available linear-time routine for inversion distance. Our experiments on simulated data sets indicate that the algorithm finds optimal medians in reasonable tim...

Block-banded matrices generalize banded matrices. We study the properties of positive definite full matrices whose inverses are -block-banded. We show that, for such matrices, the blocks in the -block band of completely determine ; namely, all blocks of outside its -block band are computed from the blocks in the -block band of . We derive fast inversion algorithms for and its inverse that, when...

Mitochondrial (mt) nucleoids were isolated with a high degree of purity from the yeast Pichia judinii, in which the mitochondrial DNA (mtDNA) is linear. Field-inversion gel electrophoresis (FIGE) reyealed that significant amounts of mtDNA could be isolated intact, as linear molecules of 41 kbp, from the isolated mt-nucleoids. Fifteen different proteins were detected in the mt-nucleoid fraction ...

Migration velocity analysis (MVA) is an approach to solve a partially linearized variant of the waveform inversion problem, i.e. linear in short scales, nonlinear in long scales. The linear inversion part is often approximated by migration in practice, which is only adjoint of linearized Born modeling operator. In this abstract, we derive the gradient formulas for short scales and long scales s...

The pKZ1 mouse chromosomal inversion assay is the only assay that has detected modulation of a mutagenic endpoint after single whole body X-irradiation with doses lower than 1 mGy. A non-linear dose response for chromosomal inversion has been observed in spleen and prostate between 0.001 mGy and 10 mGy, with doses between 0.005-0.01 mGy causing an increase in inversions and doses between 1-10 m...

Models in the form of characteristic diagrams or more specifically, in the form of engine operating maps are mostly used in the automobile industry. This yields a large amount of measurements and involves the use of advanced instrumentations. This paper shows a developed software environment, namely a toolbox for the program Matlab/Simulink developed by company Mathworks. The name of the toolbo...

This paper deals with the observer design for max-plus linear systems. The approach is based on the residuation theory which is suitable to deal with linear mapping inversion in idempotent semiring. An illustrative example allows to discuss about a practical implementation.
