A Method to Construct Depth Datum Geodesic Height Model for GNSS Bathymetric Survey
Journal of Marine Science and Engineering, 2022 Water depth measurement requires the establishment of one or more tidal stations in the survey area for synchronous water level observation, and finally the water depth is estimated to the depth datum.

Abstract Hodge decomposition and minimal models for cyclic algebras [PDF]
, 2008 We show that an algebra over a cyclic operad supplied with an additional linear algebra datum called Hodge decomposition admits a minimal model whose structure maps are given in terms of summation over trees.

Non-orthogonal geometric realizations of Coxeter groups [PDF]
, 2012 We define in an axiomatic fashion a \emph{Coxeter datum} for an arbitrary Coxeter group $W$. This Coxeter datum will specify a pair of reflection representations of $W$ in two vector spaces linked only by a bilinear paring without any integrality and non-

IET Networks, EarlyView., 2022 Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.

Social impacts of corruption upon community resilience and poverty
Jàmbá, 2017 Corruption at all levels of all societies is a behavioural consequence of power and greed. With no rulebook, corruption is covert, opportunistic, repetitive and powerful, reliant upon dominance, fear and unspoken codes: a significant component of the ...

DEVELOPMENT OF A TIME-DEPENDENT 3-PARAMETER HELMERT DATUM TRANSFORMATION MODEL: A CASE STUDY FOR MALAYSIA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 This paper aims to develop a time-dependent 3-parameter Helmert datum transformation model for Malaysia as a proposed solution to the current non-geocentric issue of the Geocentric Datum of Malaysia 2000 (GDM2000).

Estimation of Geopotential Value W0 for the Geoid and Local Vertical Datum Parameters
Remote Sensing, 2023 Unification of the global vertical datum has been a key problem to be solved for geodesy over a long period, and the main challenge for unifying the global vertical datum system is to determine the geopotential value W0 of the geoid and to calculate the ...

Heat-flow monotonicity of Strichartz norms [PDF]
, 2008 Most notably we prove that for $d=1,2$ the classical Strichartz norm $$\|e^{i s\Delta}f\|_{L^{2+4/d}_{s,x}(\mathbb{R}\times\mathbb{R}^d)}$$ associated to the free Schr\"{o}dinger equation is nondecreasing as the initial datum $f$ evolves under a certain ...

TOWARDS THE IMPLEMENTATION OF SEMI-DYNAMIC DATUM FOR MALAYSIA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 A semi-dynamic datum provides positions with respect to time while taking into account the secular and non-secular deformations, making it the best approach to adapt with the dynamic processes of the earth. Malaysia, as yet, employs a static datum, i.e.,
