Geodetic Domination Integrity of Thorny Graphs

open access: yesJournal of New Theory
The concept of geodetic domination integrity is a crucial parameter when examining the potential damage to a network. It has been observed that the removal of a geodetic set from the network can increase its vulnerability.

Analytic-graphic testing of deformities at the waterworks Pod Bukovcom [PDF]

open access: yesActa Montanistica Slovaca, 2001
The paper presents some geodetic measurement results in a frame of deformity survey of the bulk dam at the waterworks Pod Bukovcom nearby Košice. Periodic geodetic position and levelling measurement are realized on the dam since 1999.

Estimation of variance components from the measurement in a geodetic network [PDF]

open access: yesActa Montanistica Slovaca, 2005
The precision of geodetic instruments used for precise measurements in geodetic networks is described by the dispersion σ2 or the standard deviation σ. Some of geodetic instruments, like electro optic range-finder and its accuracy are characteristized by
