Reliable Bounding Zones and Inconsistency Measures for GPS Positioning using Geometrical Constraints

Hani Dbouk, Steffen Schön
2020 Acta Cybernetica  
We show that the relative volume between the polytopes and the zonotope is an inconsistency measures. Small polytope volume indicates bad consistency of the observations.  ...  We explain how the shape and the volume of the polytope are related to the positioning geometry. We show that this assignment has to be interpreted with care.  ...  The volume of the polytope indicates the inconsistency of the observations, i.e. if the volume of the polytope is small, the observations are inconsistent.  ...

Backprojection Reconstruction Algorithm Using Order Statistic Filters In Breast Tomosynthesis

László Csernetics
2009 Acta Cybernetica  
Using the projections produced by the above mentioned way, it is possible to reconstruct the 3D dataset of the imaged volume.  ...  Thus: i∈κ R i (x) ≈ i∈κ S i (x). (12) Rewriting (11) we get: i / ∈κ R i (x) ≈ N · P n (x) − 1 N · i∈κ S i (x) , (13) the approximate sum of the reconstructed values to which also the x pixel from the projection  ...

A Geometric Method for Accelerated Sphere Tracing of Implicit Surfaces

Csaba Bálint, Mátyás Kiglics
2021 Acta Cybernetica  
For this reason, we generalize the unbounding sphere and separating plane approach to unbounding quadrics [12] for any SDF. Our method consists of two steps.  ...  First, the unbounding volumes had to be compactly stored, efficiently computed, queried, and intersected with, for which revolutions of conic sections were designed with specific coefficient functions.  ...

Interval Predictors for a Class of Uncertain Discrete-Time Systems

Nacim Meslem, John Martinez
2020 Acta Cybernetica  
according to the discrete-time dynamics (13) , the initial box of the state variables e.g., [x 0 ] = ([−0.5, 0.5], [3.5, 4] ) T rotates at every iteration with an angle, say θ = π 4 , and preserves its volume  ...  For this reason, almost all approaches proposed in the literature [3, 9, 10, 11, 12, 14] attempt to compute a tight outer approximation of this reachable set.  ...
