Abstract:
The Surveying and Mapping community now has the benefit of 3-dimensional coordinates at the centimeter level, through the Global Positioning System (GPS). The reference frame for GPS, World Geodetic System of 1984 (WGS84), within which a user ascertains these coordinates is essentially geocentric. All coordinated data and mapping in Nepal are based on a non-geocentric coordinate system known as the Everest Datum of 1830. This paper tries to present a practical approach to define transformation parameters between the two coordinate systems for Nepal.

Abstract:
Questa tesi si propone di verificare l'esistenza di coordinate isoterme su una superficie. Le coordinate isoterme danno localmente una mappa conforme da una varietà riemanniana bidimensionale al piano Euclideo. Se la superficie è orientabile, allora si può dare un atlante di carte isoterme, cioè le cui coordinate associate siano isoterme. Queste coordinate esistono a patto che vengano soddisfatte certe condizioni. Il risultato nelle classi di Holder è dovuto a Korn e Lichtensten.

I propose a planar model to account for the longstanding problems of coordination.

I claim that a coordinate sentence, unlike a simple one, is too expansive a domain for the Principles of Universal Grammar (UG) to hold.

Abstract A minimal formulation using relative coordinates is presented for variational solid modeling. Computational methods developed for the kinematic modeling of mechanical systems are used to derive a minimal problem formulation.

This is done by modeling the problem as a graph, which is then analyzed to identify open loops and decoupled loops. The third method used to reduce the size of the variational problem is to tran
