Code-Based Digital Signature Schemes: Construction, Cryptanalysis and Theoretical Foundations
In recent decades, numerous code-based digital signature schemes following the hash&sign paradigm have been proposed, often turning out to be insecure and demonstrating that the cryptographic community still seems far from a satisfactory solution in this area. The first major question we pose in …

G-Code Based Toolpath Simulation for Predicting CNC Energy Consumption
… rate is variable. This thesis develops a G-code based simulation that uses a voxel mesh to virtually recreate material removal, approximating the material removal rate at discretized points in the machining process. Using an energy consumption model and machine power data, material removal …

CodeScoping: A source code based tool to software product lines scoping
Engenharia de Linhas de Produto de Software (ELPS) emergiu rapidamente como uma importante abordagem de desenvolvimento de software durantes os últimos anos. ELPS foca-se na identificação e gerenciamento dos pontos em comum (commonalities) e dos pontos de variação (variabilities) de um conjunto de …

A New Approach For Geocoding Postal Code-Based Data in Health Related Studies
… studying the spatial distribution of populations based on a certain health outcome. To conduct any form of geocoding, health researchers generally require the use of address based data (e.g. street addresses) that are commonly obtained through survey questionnaires or hospital registries. Due to …

Multiple Description Video Coding and Digital Walkthrough Compression Using Coset Codes
… The most prominent class of causal source codes used in this context are codes based on differential predictive coding. Differential predictive coding is ill-suited, however, for coding scenarios characterized by encoder uncertainty regarding decoder reconstructions. In this thesis we …

Graph-based and algebraic codes for error-correction and erasure recovery
Expander codes are sparse graph-based codes with good decoding algorithms. We present a linear-time decoding algorithm for (C,D, alpha, gamma) expander codes based on graphs with any expansion factor given that the minimum distances of the inner codes are bounded below. We also design graph-based …

Fault-tolerant quantum computer architectures using hierarchies of quantum error-correcting codes
… some use of so-called fault-tolerant components. Code-based fault-tolerance using quantum error-correcting codes is one of the most promising and versatile of the known routes for fault-tolerant quantum computation. This dissertation presents three main, new results about code-based fault-tolerant …

Optimum Damping of Beam Vibrations Using Piezoceramic Transducers
… parameters for vibration damping. A numerical code based upon Galerkin weighted-residual method is developed and the complete piezo-electro-mechanical system is designed, realized and finally tested by a standard modal testing technique. Comparisons between different shunting configurations of …

An investigation into the effects of early propping removal on the deflection of reinforced concrete beams
… a structural failure or collapse. The SANS 2001 code provides recommended propping times for beams and slabs, which can be used as a guideline by building contractors and structural designers. These propping times present a universal approach, which does not consider all the factors that affect …

Numerical study of two-dimensional smart structures
In this thesis we use a new numerical code, based upon a mixed FEM-Runge-Kutta method, for the analysis and the design of plane 2-dimensional smart structures. We applied the developed code to the study of arbitrarily shaped piezo-electromechanical (PEM) plates. This code is based on a weak …

Communicating With Graphic User Interfaces: A Comparison of Menu Selection and Menu Bypass Techniques
… relating to command bar menu and bypass code-based techniques for interacting with computers. Forty eight subjects participated. In the first phase of the experiment, mouse-, chorded key-, and function key-based menu selection techniques were compared. It was found that menus were …

On a moderate rotation theory for anisotropic shells
… finite elements are implemented in a computer code. In order to compare the results, two other theories are implemented: a refined von Karman type shell theory and a shell theory proposed by Librescu. A finite element computer code based on a degenerate 2-D shell theory is also used. A set of …

Mobile design semantics
… data created during this process, we learned code-based patterns to detect components, and trained a convolutional neural network which distinguishes between 99 icon classes with 94% accuracy. With this automated approach, we computed semantic annotations for the 72k unique UIs comprising the …
