Carbonari, Giulia. "Coordinate isoterme." Bachelor's thesis, Alma Mater Studiorum - Università di Bologna, 2016. http://amslaurea.unibo.it/10116/.

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. Chern ha notevolmente semplificato la loro dimostrazione.

Abstract:

This thesis investigates the three-dimensional (3D) coordinate transformation from a globalgeocentric coordinate system to a national terrestrial coordinate system. Numerical studies arecarried out using the Swedish geodetic data SWEREF 93 and RT90/RH70. Based on theHelmert transformation model with 7-parameters, two new models have been studied: firstly ageneral 3D affine transformation model has been developed using 9-parameters (threetranslations, three rotations and three scale factors) and secondly the model with 8-parameters(three translations, three rotations and two scale factors) has

Abstract:

In this dissertation, I pursue the idea suggested in Chomsky (1982) that coordination should be treated as an object with three dimensions. I propose a planar model to account for the longstanding problems of coordination. The types of phenomena studied here are related to Phrasal Coordinations, Gapping, Verb Phrase Deletion, and Right-Node Raising. I claim that a coordinate sentence, unlike a simple one, is too expansive a domain for the Principles of Universal Grammar (UG) to hold. The relevant domain for the application of UG principles is each separate "component part" of the coordinate se

Abstract:

Si considera il classico problema della coordinatizzazione, nell'ambito dei piani affini: dato un piano affine sintetico sotto quali ipotesi sintetiche possiamo costruire un piano affine su un corpo, ad esso isomorfo? Abbiamo presentato un'esposizione di tale problema ed una sua soluzione, seguendo l'impostazione data da R. Lingenberg e A. Bauer. Abbiamo esposto le ipotesi sotto forma di validità di teoremi di chiusura, sotto forma di esistenza di particolari collineazioni o di alcune loro specifiche proprietà ed abbiamo esplicitato l'equivalenza tra queste ipotesi.

This thesis is a study of the properties and relationships between isothermal, harmonic and characteristic coordinate systems. The proof of the existence of isothermal and characteristic coordinates on a manifold which is a graph is given using the Uniformization theorem.

It is also proven that the map from a domain parameterized by characteristic coordinates to the domain parameterized by isothermal coordinates is quasiconformal.<br>Thesis (M.S

The realm of aircraft flight dynamics analysis reaches from local static stability to global dynamic behavior. It includes aircraft performance issues as well as structural concerns.

The main contribution of this coordinate system is that one can easily visualize how the instantaneous velocity vector relates to the instantaneous rotation vector, the angular rate vect

Una teoria coerente della gravità quantistica deve tenere conto dell'invarianza sotto trasformazioni di coordinate della teoria classica della Relatività Generale. Questa invarianza è principalmente considerata nella teoria linearizzata intorno a un dato background e, di conseguenza, le trasformazioni che vengono prese in considerazione sono deformazioni regolari dell'identità (diffeomorfismi). Tuttavia, le soluzioni delle equazioni di Einstein sono invarianti sotto trasformazioni più generali che dipendono dalle soluzioni stesse e non possono quindi essere ricondotte all'identità.

The development of the 'high accuracy fiducial GPS technique', as described in this thesis, has produced results comparable with mobile VLBI and SLR systems, but in shorter observational periods and at lower costs.

In this thesis, the measurement uncertainty of Coordinate Measuring Machine (CMM) is analysed and software is designed to simulate this.

In other words, systematic part of geometric, kinematic and thermal errors are compensated with error modelling. Kinematic and geometric error model is specific for the structure of CMM under inspection. Also, a common

Free-form surfaces are increasingly used in optical and mechanical devices due to their superior optical and aerodynamic properties. The form quality plays an essential role in the characteristics of a free-form component.

This thesis focuses on investigating and developing appropriate fitting (matching) algorithms for different kinds of free-form surfaces.
