Towards a new South African geodetic datum
… to examine various criteria for choosing such a datum and thereby make a suitable datum selection. There are various ways of processing observations to the TRANSIT satellites; these techniques along with the rest of the Doppler system are described in chapter 3. Chapter 4, which contains the bulk …

Towards a geoid consistent vertical datum in South Africa
Traditionally, vertical datums have been realised through mean sea level (MSL) data, at one or more tide gauge station(s), followed by a precise levelling procedure to establish a network of benchmarks. Most countries around the world are still using mean sea level based vertical datums, and South …

Augmenting Datum Flow Chain method to support the top-down design process for mechanical assemblies
… of single parts. This thesis uses the Datum Flow Chain (DFC) for symbolic representation of mechanical assemblies and screw theory for representation of constraints between two parts. DFC captures the design intent by recording location scheme of assemblies. Screw theory can represent …

Recreational facility
… has neither order nor scale to its presence. A Datum refers to a line, plane, or volume of reference to which other elements in a composition can relate. It organizes a random pattern of elements through its regularity, continuity, and constant presence. For example, the lines of a musical staff …

Characterization of precipitation events on different space-time scales
… unseen instrument, to value the good estimate of datum,it's fundamental the metrological valuation:we have made it weighting datum uncertainties.Comparing to the traditional instruments,Pludix has presented lower relative errors.Moreover,it's effective because it measures on the ground. So it's …

Fourier Analysis of Wave Equations
… for the solution. In the classical case, the datum involved is required to have up to C2 smoothness; my results treat the low regularity case and only require Hs smoothness with fractional order s. The main tools include Fourier transform, Duhamel principle, and the method of energy estimates. …

A comparison of the least squares collocation and the fast Fourier transform methods for gravimetric geoid determination
… geoid computation. The Land Levelling Datum (LLD) is the South African vertical datum based on more than 100 years old tide gauge measurements of mean sea level (MSL). The LLD is poorly defined so an alternative is required. The SAGEOID10 (Merry, 2009) hybrid geoid model was computed …

Towards a volumetric city
… the opportunity to reinvent a new ground - a datum - which reorganizes the commercial value distribution, reinvents generic typologies and at the same time liberates the natural ground. New cityscapes can be designed above and below the new datum which permit the architecture and architect to …

The p-adic local langlands conjecture
… described up to k- isomorphism by a based root datum alone, but other groups, called rational forms of the split group, involve an action of the Galois group of k. The Galois action on the based root datum is shared by members of an inner class of k-groups, in which one k--isomorphism class is …

Linking CAD and Metrology to Explain, Demonstrate, and Teach Geometric Dimensioning and Tolerancing
… also modeled. Once the inspection data is taken, datum features on the perfect part are used to form the boundaries of the geometric tolerance zones. Through this process, students interactively learn the meaning of datum references, as well as how the various tolerances create di erent zones. …

On some partial differential equation models in socio-economic contexts - analysis and numerical simulations
… the possibility of reconstructing the initial datum given a number of observations, regarding the price and the transaction rate, is considered. Using a variational approach, the problem can be expressed as a non-linear constrained minimization problem. We show that the initial datum is …
