Iterative Connections and Abhyankar's Conjecture
… part, I introduce a new theory of modules with iterative connection. This theory unifies the theory of modules with connection in characteristic zero as given by N. Katz and the theory of iterative differential modules in positive characteristic as given by B. H. Matzat und M. van der Put. The …

Investigation into iterative feedback control
The Iterative Feedback Tuning (IFT) method is investigated in this dissertation, starting with the history and origin of this algorithm. The objective of this thesis was to apply the IFT algorithm to a physical system and the system chosen was a DC motor configured for speed control. The inertia of …

Near-capacity MIMOs using iterative detection
… performance gains, the DSTS system invokes iterative detection, where the outer code is constituted by a Recursive Systematic Convolutional (RSC) code, while the inner code is a SP demapper in one of the prototype systems investigated, while the other scheme employs a Unity Rate Code (URC) …

Iterative cross-coupling with MIDA boronates
… approach to small molecule making based on the iterative cross-coupling (ICC) of bifunctional haloboronic acid building blocks. Realizing a general ICC approach in the context of small molecule synthesis required the discovery of a ligand with the capacity to attenuate the reactivity of boronic …

VLSI Architectures for Iterative Channel Decoders
Decoder architectures for LDPC codes introduce another complexity dimension related to the on-chip interconnect bottleneck of LDPC decoders. A new parameterized-core-based design methodology targeted for scalable and programmable LDPC decoders is proposed. The methodology solves the problems of …

Two problems in iterative nonlinear maps
This thesis consists of two parts. In the first part we study the dynamics and the boundaries between basins of attraction of a logistic map defined in real 2 x 2 matrices. We show how these boundaries are of a mixed type, combining fractal and smooth regions. We find in these boundaries a very …

Iterative Monte Carlo for quantum dynamics
… This method combines the concepts of iterative propagation with the features of Monte Carlo sampling. The stepwise evaluation of the path integral circumvents the growth of statistical error with time and the use of importance sampling leads to a favorable scaling of required grid …

Integrated Photonic Iterative Processors for Computing
… the amount of computation per data I/O. Photonic iterative processors (PIPs) with optical loopback for matrix inversion and related applications happen to be one of such examples towards a more practical optical processor. By enabling direct loopback in the optical domain across different …

Iterative algorithms for lossy source coding
This thesis explores the problems of lossy source coding and information embedding. For lossy source coding, we analyze low density parity check (LDPC) codes and low density generator matrix (LDGM) codes for quantization under a Hamming distortion. We prove that LDPC codes can achieve the …

An illuminated workspace for iterative design
… digital representations in order to support the iterative design process. The illuminated workspace provides a self-contained design environment in which a number of physical, computational, statistical, and visual representations can be combined in a single creative space. This thesis describes …

Multi-heuristic theory assessment with iterative selection
Modern day machine learning is not without its shortcomings. To start with, the heuristic accuracy, which is the standard assessment criteria for machine learning, is not always the best heuristic to gauge the performance of machine learners. Also machine learners many times produce theories that …

The robust stability of iterative learning control
… the notion of the long term robust stability of iterative learning control (ILC) systems engaged in trajectory tracking, using a robust stability theorem based on a biased version of the nonlinear gap metric. This is achieved through two main results: <br/><br/>The first concerns the …
