Points, lines and diamonds: a two-sorted modal logic for projective planes
1999
Journal of Logic and Computation
We introduce a modal language for talking about projective planes. This language is two-sorted, containing formulas to be evaluated at points and at lines, respectively. ...
The language has two diamonds whose intended accessibility relations are the two directions of the incidence relation between points and lines. ...
The modal logic of projective planes In this section we introduce projective planes and our two-sorted modal logic MLG 2 for talking about them. ...

MGL2 has two sorts of variables, one sort for points and one sort for lines, and two diamonds for treating the two directions (accessibilities) of the incidence relation between points and lines. ...
Sensitivity Optimization for NV-Diamond Magnetometry
[article]
2019
arXiv
pre-print
Our analysis of sensitivity optimization establishes a foundation to stimulate development of new techniques for enhancing solid-state sensor performance. ...
Improvements to the spin dephasing time, the readout fidelity, and the host diamond material properties are identified as the most promising avenues and are investigated extensively. ...
Nitrogen was found to be the most common impurity occurring in natural diamonds, which made its presence or absence a logical basis for diamond classification. ...

Sensitivity optimization for NV-diamond magnetometry

We note that for the idealized case of a purely Lorentzian line shape p ¼ 1 and for a purely Gaussian line shape p ¼ 2. ...
Nitrogen was found to be the most common impurity occurring in natural diamonds, which made its presence or absence a logical basis for diamond classification. ...
For example, a product of two FID decays, one with p ¼ 1 and one with p ¼ 2, corresponds to a Voigt profile line shape. ...

The modal logic of affine planes is not finitely axiomatisable
2008
Journal of Symbolic Logic (JSL)
We consider a modal language for affine planes, with two sorts of formulas (for points and lines) and three modal boxes. ...
To evaluate formulas, we regard an affine plane as a Kripke frame with two sorts (points and lines) and three modal accessibility relations, namely the point-line and line-point incidence relations and ...
In [13] , Venema viewed projective planes in a somewhat more straightforward way, as Kripke frames with two sorts (points and lines), and two modal accessibility relations (incidence between points and ...

A robust evolutionary framework for multi-objective optimization
2008
Proceedings of the 10th annual conference on Genetic and evolutionary computation - GECCO '08
We argue that such a functionally decomposed and modular implementation of NSGA-II is probably the reason for it's popularity and robustness in solving various types of multi-objective optimization problems ...
NSGA-II follows three independent principles -domination principle, diversity preservation principle and elite preserving principle -which make NSGA-II a flexible and robust EMO procedure in the sense ...
As a result, for a solution in a region of the Pareto-optimal front more or less parallel to the projected plane (such as solution 'a'), the original crowded distance da and projected crowding distance ...

On probability of surf-riding in irregular seas with a split-time formulation

An approximate metric for the likelihood of surf-riding in irregular waves has been proposed as the distance, in the phase plane, between the instantaneous position of a ship and the stable surfriding ...
Further work includes studying the properties of the surfriding phase plane in irregular waves and statistics of surf-riding occurrences. ...
