THE PAST, PRESENT AND FUTURE OF PRECISION OPTICAL LEVELS [PDF]
Geodetski Glasnik, 2012 The development of digital levels in the past two decades has progressed rapidly. Although technically inferior, optical levels are not only survived in the modern age but continue to be produced and improved.

Precise levelling data processing near terraced landforms
Geodesy and Cartography, 2014 Precise levelling results are affected by the Earth’s gravity field, especially in areas of abrupt changes of landscape, such as terraced landforms. To eliminate the effect of the gravity field gradient, corrections need to be used in precise levelling ...

Roman Aqueduct Flow Estimation Using Geomatic Measurement
ISPRS International Journal of Geo-Information, 2021 The aqueducts built by the ancient Romans are among the most impressive evidence of their engineering skills. The water inside the aqueducts was transported for kilometers, exploiting only the slight but constant differences in altitude throughout the ...

Journal of Medical Toxicology, 2010 A “level” is a carpenter’s tool which simply and elegantly compares the orientation of an object to the horizon. The correct term for a measurable quantity of a substance in a specified volume or mass of a specimen is “concentration.” It is common in colloquial speech to discuss the level of an analyte in a specimen (e.g., “Let’s check the ...

Ars Mathematica Contemporanea, 2015 Bargraphs are lattice paths in N_0^2, which start at the origin and terminate immediately upon return to the x-axis. The allowed steps are the up step (0,1), the down step (0,-1) and the horizontal step (1,0). The first step is an up step and the horizontal steps must all lie above the x-axis. An up step cannot follow a down step and vice versa.

Sensors, 2023 It is acknowledged that a classical definition of the geoid-to-quasigeoid separation as a function of the simple planar Bouguer gravity anomaly is compatible with Helmert’s definition of orthometric heights.

Notre Dame Journal of Formal Logic, 2019 We introduce a hierarchy of degree structures between the Medvedev and Muchnik lattices which allow varying amounts of non-uniformity. We use these structures to introduce the notion of the uniformity of a Muchnik reduction, which expresses how uniform a reduction is.
