Explicit multiplicative relations between Gauss sums
… that all multiplicative relations between Gauss sums essentially follow from the Davenport-Hasse product formula and the norm relation for Gauss sums. While this is known to be false, very few counterexamples, now known as sign ambiguities, have been given. Here, we provide an explicit …

Accelerating Gauss-Newton filters on FPGA's
… algorithms such as the original nonrecursive Gauss-Newton filter on which the Kalman filter is based. This dissertation investigates the acceleration of such a filter using FPGA technology, making use of custom, reduced-precision number formats.

Gauss-type formulas for linear functionals
… by solving a nonlinear system of equations, for Gauss harmonic interpolation formulas which are useful for approximating, the solution of the Dirichlet problem. We also discuss approximations for integrals of the form I(f) = (1/2πi) ∫<sub>L</sub> (f(z)/(z-α)) dz. Our approximations shall be of …

Concentrated Gauss Curvature in Shape-Programmed Shells
… Our focus will be on novel ways to program Gauss curvature, motivated by its deep mechanical consequences - principally it imparts strength, since Gauss-curved shells cannot be flattened without expensive stretch. Concentrated Gauss curvature will be of particular interest, offering …

Parallel Gauss-Newton method for CP decomposition
In this thesis, we formulate the Gauss-Newton algorithm to make it viable for running on distributed memory architectures and comparative to Alternating least squares algorithm for CP decomposition. Alternating least squares may exhibit slow or no convergence, especially when high accuracy is …

A Gauss pseudospectral transcription for optimal control
… to the dynamic equations at a set of Gauss collocation points. The optimality conditions of the NLP have been found to be equivalent to the discretized optimality conditions of the continuous control problem, which is not true of other pseudospectral methods. This result indicates that …

Gauss-newton Based Learning For Fully Recurrent Neural Networks
… of RTRL is presented, that is based on the Gauss-Newton method. The method itself is an approximate Newton's method tailored to the specific optimization problem, (non-linear least squares), which aims to speed up the process of FRNN training. The new approach stands as a robust and …

On improving the performance of the Gauss-Newton filter
The Gauss-Newton filter is a tracking filter developed by Norman Morrison around the same time as the celebrated Kalman filter. It received little attention, primarily due to the computation requirements at the time. Today computers have vast processing capacity and computation is no-longer an …

Four-wave mixing with hermite-gauss modes in rubidium vapor
… incident beams, more specifically of the Hermite-Gauss (HG) modes, is transferred to the generated signal in this nonlinear process. For the experiment, we used a continuous wave diode laser to excite a sample of Rubidium atoms, on the ⁸⁵Rb D2 line, tuned to the frequency of the 5²S_(1/2) (𝐹 = 3) …

The polyhedral Gauss map and discrete curvature measures in geometric modelling.
… the TAC is measured by means of the Polyhedral Gauss Map (PGM) of vertices. This is a representation of the curvature of a vertex as an area on the surface of a sphere. Positive and negative components of the curvature of a vertex are distinguished as spherical polygons on the PGM. Core …

Desarrollo de nuevos algoritmos para el cálculo de la proyección Gauss-Krüger
… projection of the ellipsoid was derived by Gauss as a special case of his general theory of conformal representation, and was introduced by him into the Survey of Hanover between 1820 and 1830. A method for the full development of the formulae, using a symbolic calculus program is developed, …

Gravitational wave cosmology in general relativity and Einstein-scalar-Gauss-Bonnet gravity.
… General Relativity (GR) and Einstein-scalar-Gauss-Bonnet (EsGB) gravity. We first investigate the spacetime singularities of plane GWs in GR and find that only few of them are free of spacetime singularities. In particular, we show explicitly that in the BJR coordinates the singularity can be …

Large-Scale Circuit Simulation (Vlsi, Spice, Premos, Analysis, Sequencing, Nonlinear, Iteration, Gauss-Seidel)
The simulation of VLSI circuits falls beyond the capabilities of conventional circuit simulators like SPICE. On the other hand, conventional logic simulators can only give the results of logic levels "1" and "0" with the attendant loss of detail in the waveforms. The aim of developing large-scale …

The Geodesic Gauss Map and Ruh-Vilms theorem for a Hypersurface in S^{n}
… The Ruh-Vilms theorem is a statement about the Gauss map for a submanifold of R^{n+1} . Our aim is to prove, an isometrically immersed hypersurface f : M −→ S^{n} has constant mean curvature if and only if the Gauss map of γ is harmonic. Here we provide a proof of the Ruh-Vilms result using …

OVERCONVERGENT MODULAR AND DE RHAM SHEAVES AND P-ADIC ITERATION OF THE GAUSS-MANIN CONNECTION
We construct p-adic iteration of the Gauss-Manin connection on overconvergent sheaves of de Rham classes on Hilbert modular varieties in the case p is unramified in the totally real field. This is a generalization of the work of Andreatta-Iovita in the case of elliptic curves, using a technique …
