Resumen
Two novel methods to reduce the number of random test patterns required to fully test a circuit are proposed in this thesis. In the concept of correlated random patterns, reductions in a circuit's random pattern test length are achieved by taking advantage of correlations measured between values applied at different input positions in a complete deterministic test set. Instead of being generated independently, correlated inputs have their random values generated from a common source with each input's value then individually biased at a rate necessary to match the measured correlation.

Approved for public release; distribution is unlimited<br>Multilevel military communications security can be implemented with the notion of masterkeys. Naval message traffic is transmitted with restricted character set and optionally files are compressed. Both character translation and data compression can be used as add-on data encryption. A masterkey is constructed from a set of service keys from which masterkey is allowed to access. This thesis presents the principles of multilevel security with restricted character translation, data compression, and masterkey implementation.

Resumen
This thesis studies the generalization behavior of algorithms in Sample Compression Settings. It extends the study of the Sample Compression framework to derive data-dependent bounds that give tighter guarantees to the algorithms where data-independent bounds such as the VC bounds are not applicable. It also studies the interplay between sparsity and the separating margin, of the classifier and shows how new compression based data-dependent bounds can be obtained that can exploit these two quantities explicitly. These bounds not only provide tight generalization guarantees but by themselves pr

Resumen
With rapid development in semiconductor technology, today's large and complex integrated circuits require a large amount of test data to achieve desired test coverage. Test cost, which is proportional to the size of the test set, can be reduced by generating a small number of highly effective test patterns. Automatic Test Pattern Generators (ATPGs) generate effective deterministic test patterns for different fault models and can achieve high test coverage. To reduce ATPG-produced test set size, design for test (DFT) methods can be used to further improve the ATPG process and apply generated te

Resumen
Densification is a well-known method for improving the mechanical properties of wood. In the present study, unmodified and furfurylated wood samples were densified and submitted to cyclic water storage tests and cyclic alternating climate tests. Swelling coefficients and spring-back data were determined for the evaluation of the quality of densification. The study shows that results depend on the test method applied. Simple water storage tests do not reflect the behavior of densified wood in the high humidity range. The spring-back data of unmodified samples are more influenced by the testing

Resumen
A finalidade deste estudo foi verificar a resistência ao deslocamento de restaurações de Classe IV, ressaltando a sua capacidade de retenção com e sem a associação de pino(s) dentinários, bem como a comparação entre dentes humanos e bovinos, visando este último como possível substrato a dentes humanos em testes laboratoriais. Foram realizadas 60 cavidades de Classe IV com 6mm no sentido incisocervical e 3mm no sentido mesiodistal, tanto em dentes humanos como bovinos, com um bisel de 1mm de extensão, as quais foram divididas nos seguintes grupos: · G1- restaurações sem pino, sem condicionament

Resumen
Este trabalho tem como objetivo investigar o comportamento pós-pico de pilares com concretos de alta resistência confinados com e sem adição de fibras metálicas, submetidos à flexo-compressão. Para tanto, realizou-se inicialmente uma extensa revisão bibliográfica sobre o tema, na qual, elencaram-se os principais fatores que influenciam o comportamento pós-pico desses elementos estruturais. Em seguida, desenvolveram-se estudos paramétricos com o intuito de estabelecer os modos de influência de cada fator. Com base nesses estudos preliminares, um programa experimental, dividido em duas fases, fo

Resumen
Antarctic ice shelves control the ice flux from the continent to the ocean. As such, they play a major role in the stability of the ice sheet and its potential contribution to sea level rise, especially in the context of global change. Below some of these ice shelves, marine ice can be found which is a product of the Deep Thermohaline Circulation. Due to its specific genetic process, marine ice has intrinsic physical (grain size, ice fabric, bubble content, ) and chemical (impurities, water stable isotopes) properties, that differ from those of 'meteoric ice' formed on the continent through sn

Resumen
Understanding the interaction of sea ice with offshore structures is of primary importance for the development of technology in cold climate regions. The rheological properties of sea ice (strength, creep, viscosity) as well as the roughness of the contact surface are the main factors influencing the type of interaction with a structure. A device was developed and designed and small scale laboratory experiments were carried out to study sea ice frictional interaction with steel material by means of a uniaxial compression rig. Sea-ice was artificially grown between a stainless steel piston (o

Les matériaux composites utilisés actuellement en mer sont presque tous fabriqués avec des résines thermodurcissables (polyester, époxy). Il existe aujourd’hui une alternative aux matrices thermodurcissables: les matrices thermoplastiques (PP, PA, PPS, PEEK…). Celles-ci offrent la possibilité d’une mise en forme par chauffage local associée à des propriétés mécaniques très intéressantes et un recyclage possible en fin de vie. Les raisons pour l’adaptation lente de ces matériaux est qu’ils nécessitent une mise en œuvre complètement différente du fait de leur microstructure particulière et du ma
